Description

Bidirectional display module, electronic device, and method of using the electronic device

The present invention relates to an electronic device, and in particular to a two-way display module, an electronic device and a method for using the electronic device.

With the change of hybrid working mode, two-in-one and form-changing electronic devices (such as laptops) that take into account the convenience of use and flexible task execution are becoming popular again. However, traditional laptops require greater movement and force to flip the screen to change its usage mode. Or, a more complex hinge structure is required to achieve a simpler form change. Even worse, it is necessary to pay more cost to directly import the display screen into two different screens in front and back. However, using the above method, no matter designing the structure or operating it, it is necessary to pay a considerable cost.

The present invention provides a bidirectional display module, an electronic device and a method for using the electronic device, which can switch the display direction according to needs or situations to achieve the effect of using a single screen to provide a bidirectional display, thereby obtaining a good display experience.

The bidirectional display module includes a first dimming plate, a first light guide plate, a second dimming plate, a display panel, a third dimming plate, a second light guide plate and a fourth dimming plate in sequence from the first side to the second side. The first light guide plate is arranged on the first transmission path of the illumination light beam to guide the illumination light beam to be transmitted toward the first side and the second side. The second light guide plate is arranged on the second transmission path of the illumination light beam to guide the illumination light beam to be transmitted toward the first side and the second side. The display panel is used to convert the illumination light beam into a display light beam.

In order to make the above features and advantages of the present invention more clearly understood, embodiments are specifically cited below and described in detail with reference to the accompanying drawings.

FIG1 is a schematic diagram of a two-way display module of an embodiment of the present invention. FIG2 is a schematic diagram of a usage scenario of an electronic device of an embodiment of the present invention. FIG3 is a schematic diagram of another usage scenario of an electronic device of an embodiment of the present invention. Please refer to FIG1 to FIG3. The present embodiment provides an electronic device 10, including a hinge structure 20, a first body 30 and a second body 40. Among them, the first body 30 and the second body 40 are both pivotally connected to the hinge structure 20. The electronic device 10 is, for example, a notebook computer, and the first body 30 and the second body 40 are, for example, a display end configured with a screen and a logical end configured with an input interface (such as a keyboard, a sensing area), respectively, but the present invention does not limit the detailed types and methods of component configuration in the first body 30 and the second body 40. The first body 30 includes a two-way display module 100. In addition to executing the general one-way display application, it can also be used to selectively switch between two-way display or full transparent display to apply different direction display technology, different area display technology or augmented reality (AR) technology.

Please continue to refer to FIG. 1. In this embodiment, the bidirectional display module 100 is used to provide a display light beam L2 containing display screen information to at least one of the first side A1 and the second side A2 to switch the display state. The bidirectional display module 100 includes a first dimming plate 110, a first light guide plate 120, a second dimming plate 130, a display panel 140, a third dimming plate 150, a second light guide plate 160 and a fourth dimming plate 170 in sequence from the first side A1 to the second side A2.

The first light guide plate 120 and the second light guide plate 160 with the same function are, for example, light guide plates, respectively disposed on the first transmission path P1 and the second transmission path P2 of the illumination light beam L1. The first light guide plate 120 is used to guide the illumination light beam L1 of the first transmission path P1 to the first side A1 and the second side A2, and the second light guide plate 160 is used to guide the illumination light beam L1 of the second transmission path P2 to the first side A1 and the second side A2. The display panel 140 is, for example, a liquid crystal display panel (LCD Panel), used to convert the illumination light beam L1 into a display light beam L2. When the display state is to provide the display light beam L2 toward the second side A2, the illumination light beam L1 is transmitted along the first transmission path P1 to the first light guide plate 120, and when the display state is to provide the display light beam L2 toward the first side A1, the illumination light beam L1 is transmitted along the second transmission path P2 to the second light guide plate 160. However, the present invention does not limit the type or form of the first light guide plate 120, the second light guide plate 160 and the display panel 140 in the bidirectional display module 100, and the detailed structure and implementation method thereof can be sufficiently taught, suggested and implemented by the common knowledge in the relevant technical field, and therefore will not be described in detail.

The first dimming plate 110, the second dimming plate 130, the third dimming plate 150 and the fourth dimming plate 170 are, for example, polymer-dispersed liquid crystal (PDLC), used as an electrically controlled light valve, which can allow the light beam to pass completely, partially or not pass at all according to the power-on state. For example, in this embodiment, when the first dimming plate 110, the second dimming plate 130, the third dimming plate 150 or the fourth dimming plate 170 is powered on (i.e. activated), it presents a transparent state or an atomized state, and when the first dimming plate 110, the second dimming plate 130, the third dimming plate 150 or the fourth dimming plate 170 is not powered on (i.e. closed), it presents a light-shielding state. The transparent state is used to allow the light beam to pass through, the atomized state is used to allow the light beam to obtain a uniform effect, and the shading state can be used to block the light beam or reflect the light beam. However, the present invention does not limit the materials of the first dimming plate 110 to the fourth dimming plate 170 or the method of changing the optical state. Specifically, in this embodiment, the first dimming plate 110 and the fourth dimming plate 170 are switched to the light-transmitting state or the light-shielding state according to the display state, and the second dimming plate 130 and the third dimming plate 150 are switched to the light-transmitting state or the atomized state according to the display state.

FIG. 4 and FIG. 5 are exploded schematic diagrams of a bidirectional display module of an embodiment of the present invention in different display states. Please refer to FIG. 4 first. The bidirectional display module 100 can be switched to different display states according to needs or situations. For example, in this embodiment, when the display state is to provide a display light beam L2 toward the second side A2 (i.e., the illumination light beam L1 is transmitted to the first light guide plate 120 along the first transmission path P1), the first dimming plate 110 is in a light-shielding state, the second dimming plate 130 is in an atomized state, and the third dimming plate 150 and the fourth dimming plate 170 are both in a light-transmitting state. Next, please refer to FIG. 5. When the display state is to provide the display light beam L2 toward the first side A1 (i.e., the illumination light beam L1 is transmitted to the second light guide plate 160 along the second transmission path P2), the first dimming plate 110 and the second dimming plate 130 are both in a light-transmitting state, the third dimming plate 150 is in an atomized state, and the fourth dimming plate 170 is in a light-shielding state. Therefore, the bidirectional display module 100 can switch the display direction according to needs or situations to achieve the effect of providing bidirectional display using a single screen, thereby obtaining a good display experience. In another display state, the first dimming plate 110 and the fourth dimming plate 170 can be further adjusted to a light-transmitting state to form a fully transparent screen or a semi-transparent screen, so as to be applied to the augmented reality technology shown in FIG. 3.

FIG6 is an exploded schematic diagram of a plurality of display areas spliced together using the bidirectional display module of FIG1. Please refer to FIG6. Different from the embodiments of FIG4 and FIG5 described above, the bidirectional display module 100 may include a plurality of display areas spliced together, and the display state of at least one of the plurality of display areas is different from the display state of at least another of the plurality of display areas. For example, in the present embodiment, the bidirectional display module 100 includes a first display area D1 and a second display area D2 that are symmetrical on the left and right, and the first display area D1 provides a display light beam L2 toward the first side A1, and the second display area D2 provides a display light beam L2 toward the second side A2. In the first display area D1, the first dimming plate 110 and the second dimming plate 130 are both in a light-transmitting state, the third dimming plate 150 is in an atomized state, and the fourth dimming plate 170 is in a light-shielding state. In the second display area D2, the first dimming plate 110 is in the light-shielding state, the second dimming plate 130 is in the atomized state, and the third dimming plate 150 and the fourth dimming plate 170 are both in the light-transmitting state. Therefore, the effect of simultaneously partitioning and bidirectionally displaying on a single screen can be further achieved.

Fig. 7A to Fig. 7F are front view schematic diagrams of multiple display areas displayed in zones. Fig. 8A to Fig. 8F are another front view schematic diagrams of multiple display areas displayed in zones. Fig. 9 is another front view schematic diagram of multiple display areas displayed in zones. Please refer to Fig. 1 and Fig. 7A to Fig. 7F. In some embodiments, the bidirectional display module 100 may include nine display areas D spliced together, arranged in an array, and the illumination light beam L1 may be selectively transmitted from one to two of the three columns of display areas D in the first light guide plate 120 or the second light guide plate 160 into the light guide plate, so that the bidirectional display module 100 generates a display light beam from at least one column of display areas D corresponding to the transmission of the illumination light beam L1. Please refer to Fig. 1 and Fig. 8A to Fig. 8F. Similarly, in some other embodiments, the illumination light beam L1 may also be selectively transmitted from one to two rows of the three rows of display areas D in the first light guide plate 120 or the second light guide plate 160 to enter the light guide plate, so that the bidirectional display module 100 generates a display light beam from at least one row of the display area D corresponding to the transmission of the illumination light beam L1. Please refer to Figures 1 and 9. In another embodiment, the illumination light beam L1 may be selectively transmitted from one to two rows of the three columns of display areas D in the first light guide plate 120 or the second light guide plate 160 and one to two rows of the three rows of display areas D to enter the light guide plate, so that the bidirectional display module 100 generates a display light beam from the display area D of a special shape (for example, a cross shape is shown in Figure 9) corresponding to the transmission of the illumination light beam L1.

Figures 10A to 10E are front views of multiple display areas for automatic adjustment of partitioned display. Please refer to Figure 1 and Figures 10A to 10E. In application, in a two-way display module 100 having multiple display areas D, in the corresponding display area D, the user interface (UI) pattern U presented can be automatically adjusted according to the shape of the display area D. For example, when the display area D being displayed is in a vertical direction, the user interface pattern U presented can be automatically adjusted to a vertical distribution, and when the display area D being displayed is in a horizontal direction, the user interface pattern U presented can be automatically adjusted to a horizontal distribution. Therefore, the experience effect can be improved.

FIG. 11A to FIG. 11C are schematic diagrams of a bidirectional display module including a light source module in different display states according to an embodiment of the present invention. Please refer to FIG. 11A to FIG. 11C. The bidirectional display module 100A of the present embodiment is similar to the bidirectional display module 100 shown in FIG. 1. The difference between the two is that, in the present embodiment, the bidirectional display module 100A also includes a light source module 200, and the light source module 200 includes a light-emitting element 202 for providing an illumination beam L1 to the first light guide plate 120 or the second light guide plate 160. However, the present invention does not limit the type of the light-emitting element 202. In addition, in some embodiments, the light-emitting element 202 can be used in conjunction with an optical lens to facilitate transmission, which will not be described in detail in the subsequent description, and the present invention is not limited thereto. In this embodiment, the light source module 200 further includes a slide rail 204, and the light-emitting element 202 is disposed on the slide rail 204, for example, a combination of a permanent magnet rail and electromagnets disposed at both ends, but not limited thereto. The position of the light-emitting element 202 corresponds to the first light guide plate 120 or the second light guide plate 160 through the movement of the slide rail 204, so as to switch different display directions. When the display state is to provide the display beam L2 toward the second side A2, the light-emitting element 202 moves corresponding to the first light guide plate 120, and when the display state is to provide the display beam L2 toward the first side A1, the light-emitting element 202 moves corresponding to the second light guide plate 160. For example, in this embodiment, the light source module 200 further includes a first power source 206 and a second power source 208, which are electrically connected to activate the light-emitting element 202 to emit light. In other words, when the light-emitting element 202 corresponds to the position of the first light guide plate 120 through the action of the slide rail 204, the first power source 206 is electrically connected to the light-emitting element 202, so that the light-emitting element 202 is activated to provide the illumination beam L1. When the light-emitting element 202 corresponds to the second light guide plate 160 through the action of the slide rail 204, the second power source 208 is electrically connected to the light-emitting element 202, so that the light-emitting element 202 is activated to provide the illumination beam L1.

FIG. 12A and FIG. 12B are schematic diagrams of a bidirectional display module of an embodiment of the present invention including another light source module in different display states. Please refer to FIG. 12A and FIG. 12B. The bidirectional display module 100B of this embodiment is similar to the bidirectional display module 100 shown in FIG. 1. The difference between the two is that in this embodiment, the bidirectional display module 100B also includes a light source module 210, and the light source module 210 includes a light emitting element 202 similar to the embodiment of FIG. 11A, a first light valve element 214 configured on the first transmission path P1, and a second light valve element 216 configured on the second transmission path P2. The first light valve element 214 and the second light valve element 216 are used to control the blocking of the light beam or the passing of the light beam by electrical changes. Specifically, the light source module 210 further includes two reflectors 218 respectively arranged on the first transmission path P1 and the second transmission path P2. When the display state is to provide the display light beam L2 toward the second side A2, the first light valve element 214 is used to allow the illumination light beam L1 to pass through and the second light valve element 216 is used to block the illumination light beam L1 from passing through. When the display state is to provide the display light beam L2 toward the first side A1, the second light valve element 216 is used to allow the illumination light beam L1 to pass through and the first light valve element 214 is used to block the illumination light beam L1 from passing through. In this embodiment, the first shutter element 214 and the second shutter element 216 are, for example, black and white liquid crystal layers. When the light beam needs to be switched between the two sides, one side is energized to make it transparent, thereby allowing the single-side light beam to pass through to achieve the effect of switching sides for display.

FIG. 13A and FIG. 13B are schematic diagrams of a bidirectional display module of an embodiment of the present invention including another light source module in different display states. Please refer to FIG. 13A and FIG. 13B. The bidirectional display module 100C of this embodiment is similar to the bidirectional display module 100 shown in FIG. 1. The difference between the two is that in this embodiment, the bidirectional display module 100C further includes a light source module 220, and the light source module 220 includes a light-emitting element 222 and a rotatable reflector 224. When the display state is to provide a display light beam L2 toward the second side A2, the rotatable reflector 224 rotates to reflect the illumination light beam L1 and transmit it along the first transmission path P1. When the display state is to provide the display beam L2 toward the first side A1, the rotating reflector 224 rotates to reflect the illumination beam L1 and transmits it along the second transmission path P2. Therefore, the illumination beam L1 is adjusted to irradiate with the rotating reflector 224, thereby forming a directional light source, which can be irradiated in different directions. A strong magnetic material that can be controlled by an electromagnet is configured at the end of the rotating reflector 224, and the rotating reflector 224 is rotated to switch the direction.

FIG. 14A and FIG. 14B are schematic diagrams of a bidirectional display module of an embodiment of the present invention including another light source module in different display states. Please refer to FIG. 14A and FIG. 14B. The bidirectional display module 100D of this embodiment is similar to the bidirectional display module 100 shown in FIG. 1. The difference between the two is that in this embodiment, the bidirectional display module 100D further includes a light source module 230, and the light source module 230 includes a light emitting element 232 and a driving element 234, and the light emitting element 232 is arranged on the driving element 234. The driving element 234 is, for example, a micro motor, which is used to match the light beam to adjust the angle of illumination, thereby forming a directional light source, and different directions (for example, 90 degrees apart) can be selected for illumination. The driving element 234 can be controlled by a program to change the direction of illumination, but the present invention is not limited thereto. When the display state is to provide the display beam L2 toward the second side A2, the driving element 234 rotates to drive the light-emitting element 232 to provide the illumination beam L1 along the first transmission path P1. When the display state is to provide the display beam L2 toward the first side A1, the driving element 234 rotates to drive the light-emitting element 232 to provide the illumination beam L1 along the second transmission path P2.

The electronic device 10A of the present embodiment is similar to the electronic device 10 shown in FIG. 2 . The difference between the two is that, in the present embodiment, the light source module 200 is disposed at the second body 40 at the logical end. The light source module 200 includes a light emitting element 202 for providing an illumination beam L1 to the bidirectional display module 100. In addition, in the present embodiment, the electronic device 10A further includes a first light guide element 50 connected to the first body 30 and the second body 40 for guiding the illumination beam L1 to the bidirectional display module 100. The first light guide element 50 is, for example, an optical fiber having soft material properties, but the present invention is not limited thereto. It is also worth mentioning that the second body 40 of the present embodiment is provided with a buffer space E1, so when the electronic device 10A is in an unfolded state (as shown in FIG. 15B ), the first light guide element 50 located in the buffer space E1 can be stretched in the space.

FIG. 16A and FIG. 16B are schematic diagrams of an electronic device in another embodiment of the present invention in different states. The electronic device 10B of the present embodiment is similar to the electronic device 10 shown in FIG. 2 . The difference between the two is that, in the present embodiment, the light source module 200 is disposed on the second body 40. The light source module 200 includes a light emitting element 202 for providing an illumination beam L1 to the bidirectional display module 100. In addition, in the present embodiment, the electronic device 10B further includes a second light guide element 60, which is disposed on the first body 30 and connected to the bidirectional display module 100. The second light guide element 60 includes a first light inlet 62 and a second light inlet 64. When the electronic device 10B is in a closed state (as shown in FIG. 16A ), the illumination light beam L1 from the light-emitting element 202 is transmitted from the first light inlet 62 to the two-way display module 100, and when the electronic device 10B is in an open state (as shown in FIG. 16B ), the illumination light beam L1 from the light-emitting element 202 is transmitted from the second light inlet 64 to the two-way display module 100. Specifically, in this embodiment, a reflector 66 is disposed inside the second light-guiding element 60, which is used to rotate to a specific angle according to a mechanical structure (not shown) inside the electronic device 10B, thereby reflecting the illumination light beam L1 and continuing to transmit it from the light inlet to the two-way display module 100.

FIG. 17A and FIG. 17B are schematic diagrams of an electronic device in another embodiment of the present invention in different states.

The difference between the two is that in this embodiment, the second light guide element 60A is configured with a plurality of fixed reflective plates 66A to reflect the illumination beam L1 and make the interior of the second light guide element 60A present a total reflection state, thereby the reflected illumination beam L1 is further transmitted from the light inlet to the bidirectional display module 100.

FIG. 18A and FIG. 18B are schematic diagrams of an electronic device in another embodiment of the present invention in different states. In this embodiment, the light source module 200 is disposed in the rotating shaft structure 20, wherein FIG. 18A and FIG. 18B respectively show the corresponding position schematic diagram of the rotating shaft structure 20 and the corresponding position schematic diagram of the light source module 200. The electronic device 10D of this embodiment is similar to the electronic device 10 shown in FIG. 2, and the difference between the two is that in this embodiment, the light source module 200 is configured in the rotating shaft structure 20. The light source module 200 includes a light-emitting element 202 for providing an illumination beam L1 to the bidirectional display module 100. In this embodiment, the light-emitting element 202 includes a first sub-light-emitting element 202A and a second sub-light-emitting element 202B, which are respectively configured to provide an illumination beam L1 in different directions. For example, when the electronic device 10D is in a closed state, the first sub-light emitting element 202A is activated to provide the illumination beam L1 to the two-way display module 100. When the electronic device 10D is in an open state, the second sub-light emitting element 202B is activated to provide the illumination beam L1 to the two-way display module 100. When the electronic device 10D switches between the closed state and the open state, the light emitting direction of the light source module 200 can be confirmed by the touch sensor element 22, but the present invention is not limited thereto.

FIG. 19A and FIG. 19B are schematic diagrams of an electronic device in another embodiment of the present invention in different states. The electronic device 10E of this embodiment is similar to the electronic device 10D shown in FIG. 18A. The difference between the two is that in this embodiment, when the electronic device 10D switches between the closed state and the unfolded state, the light source module 200 rotates with the shaft structure 20. Specifically, the light-emitting element 202 can be fixed on the shaft structure 20, and the shaft structure 20 also includes a light-transmitting shell 24, which is arranged at the angle of the shaft structure 20 corresponding to the rotatable angle of the first body 30. Therefore, when the first body 30 is opened, the rotating shaft structure 20 drives the light emitting element 202 to rotate to provide an illumination light beam L1 to be sequentially transmitted to the light-transmitting housing 24 and the two-way display module 100 .

FIG. 20A and FIG. 20B are schematic diagrams of an electronic device in another embodiment of the present invention in different states. In the electronic device 10F of the present embodiment, the light source module 200 can be disposed at the logic end of the second body 40 and directly provide the illumination beam L1 to the bidirectional display module 100, and the first body 30 also includes a display end light source module 32 (such as the light source module of FIG. 11A to FIG. 14B), so the display end illumination beam (not shown) can also be provided from the first body 30 to the bidirectional display module 100. Specifically, when the electronic device 10F is in a closed state (as shown in FIG. 20A ), the light source module 200 provides the illumination beam L1 to the two-way display module 100 , and when the electronic device 10F is in an unfolded state (as shown in FIG. 20B ), the display end light source module 32 provides the display end illumination beam to the two-way display module 100 .

Furthermore, in this embodiment, the above-mentioned implementation method can also be applied in different scenarios. In one scenario, the electronic device 10F is in operation, and the first body 30 is opened and closed relative to the second body 40 without executing the shutdown step. When the first body 30 is about to touch the second body 40 (for example, the angle θ between the first body 30 and the second body 40 is less than a specific angle), the display-side light source module 32 will be turned off and switched to the light source module 200 at the logic end. On the contrary, when the first body 30 is far away from the second body 40 (for example, the angle θ between the first body 30 and the second body 40 is greater than a specific angle), the light source module 200 will be turned off and switched to the display-side light source module 32. In another scenario, when the electronic device 10F is directly turned on in a closed state, the light source module 200 located in the second body 40 will be activated once the system is running. When the light source module 200 determines that this is a closed state (for example, the angle θ between the first body 30 and the second body 40 is less than a specific angle), it will be activated and provide the illumination beam L1.

FIG. 21A to FIG. 21E are schematic diagrams of an electronic device in another embodiment of the present invention in different states. The electronic device 10G of this embodiment is similar to the electronic device 10F shown in FIG. 20A . The difference between the two is that, in this embodiment, the second body 40 further includes a light-guiding element 42, which is arranged on the transmission path of the illumination light beam L1 from the light source module 200, so as to guide the illumination light beam L1 to emit light from a specific display area D3 (see FIG. 21D ). Specifically, in this embodiment, the light source module 200 can be arranged on the second body 40, and the light-guiding element 42 is used to make the illumination light beam L1 provided by the light source module 200 uniformly guided into the light-guiding material, so that the specific display area D3 corresponding to the distribution position of the light-guiding element 42 in the first body 30 emits light, while other undistributed areas do not emit light. In this embodiment, the light guide element 42 is disposed at a position where the palm rest is located, for example. Therefore, when the first body 30 is unfolded upward, the illumination light beam L1 from the second body 40 can pass through the light guide element 42 to illuminate the area where the palm rest is located, thereby enhancing a good experience effect. When the first body 30 is covered downward, the illumination light beam L1 from the second body 40 can pass through the bidirectional display module 100 of the first body 30 to illuminate, thereby making the area where the palm rest of the second body 40 is located become a clearer area on the bidirectional display module 100.

FIG. 22A to FIG. 22E are schematic diagrams of an electronic device in another embodiment of the present invention in different states. Please refer to FIG. 22A to FIG. 22E.

The difference between the two is that in this embodiment, the position distribution where the light guide element 42 is configured is, for example, the area where the keyboard is located. Therefore, when the first body 30 is unfolded upward, the illumination light beam L1 from the second body 40 can pass through the light guide element 42 to make the area where the keyboard is located illuminated, thereby enhancing the good experience effect. When the first body 30 is covered downward, the illumination light beam L1 from the second body 40 can pass through the two-way display module 100 of the first body 30 , thereby making the area where the keyboard of the second body 40 is located become a clearer area on the two-way display module 100 .

The difference between the two is that, in this embodiment, the light guide element 42 is configured at a location where, for example, the touch panel is located. Therefore, when the first body 30 is unfolded upward, the illumination light beam L1 from the second body 40 can pass through the light guide element 42 to illuminate the area where the touch panel is located, thereby enhancing a good experience effect. When the first body 30 is covered downward, the illumination light beam L1 from the second body 40 can pass through the bidirectional display module 100 of the first body 30 to illuminate, thereby making the area where the touch panel of the second body 40 is located become a clearer area on the bidirectional display module 100.

FIG. 24 and FIG. 25 are schematic diagrams of an electronic device in another embodiment of the present invention in different states. Please refer to FIG. 24 and FIG. 25. In some scenarios, when the electronic device 10J is in a closed state, the display state of the electronic device 10J may be to provide a display beam L2 toward a side away from the second body 40 (as shown on the right side of FIG. 25), and when the electronic device 10J is in an unfolded state, the display state of the electronic device 10J is to provide a display beam L2 toward a side of the second body 40 (as shown on the left side of FIG. 25). The electronic device 10J of this embodiment is similar to the electronic device 10 shown in FIG. 2. The difference between the two is that in this embodiment, the second body 40 is further configured with a sensing element 44, such as a combination of an infrared transmitter, an infrared sensor and a spring structure, for sending a signal to switch the display direction of the bidirectional display module 100 when the electronic device 10J switches between the closed state and the unfolded state.

FIG26 is a schematic diagram of an electronic device in another embodiment of the present invention in different states. The electronic device 10K of this embodiment is similar to the electronic device 10 shown in FIG2 . The difference between the two is that in this embodiment, when the electronic device 10K is in the unfolded state, the display state of the electronic device 10K is to provide a display light beam L2 toward a side away from the second body 40, so as to facilitate the application of augmented reality technology. Specifically, in this embodiment, when the angle θ between the first body 30 and the second body 40 is less than 180 degrees, for example, the placement direction of the electronic device 10K can be detected through the pressure sensor additionally configured in the first body 30 and the second body 40 and the gyroscope additionally configured in the shaft structure 20, and it can be evaluated that the tent mode is in effect at this time (as shown on the right side of FIG. 26 ). Then, the two-way display module 100 configured in the first body 30 automatically switches to provide the display light beam L2 toward the side away from the second body 40, and can be used as an information center or a home entertainment center.

FIG27 is a flow chart of the steps of the method for using the electronic device of an embodiment of the present invention. Please refer to FIG27. The step flow of the method for using the electronic device shown in this embodiment can be applied to at least the electronic device 10 shown in FIG1, so the following description takes the electronic device 10 applied to FIG1 as an example, but the present invention is not limited thereto. In the method for using the electronic device 10 of this embodiment, step S300 is first performed to provide an illumination light beam L1 to at least one of the first light guide plate 120 and the second light guide plate 160 of the bidirectional display module 100. That is, in different display states, the illumination light beam L1 can be provided to the first light guide plate 120 or the second light guide plate 160, or provided to both the first light guide plate 120 and the second light guide plate 160 for light guiding. Then, after the above steps, step S301 is executed to switch the first dimming plate 110 and the fourth dimming plate 170 of the bidirectional display module 100 to the light-transmitting state or the light-shielding state according to the display state. And step S302 is executed to switch the second dimming plate 130 and the third dimming plate 160 of the bidirectional display module 100 to the light-transmitting state or the atomized state according to the display state. For example, when the display state of the electronic device 10 is to provide the display light beam L2 toward the second side A2, the first dimming plate 110 to the fourth dimming plate 170 will be switched to the light-shielding state, the atomized state, the light-transmitting state and the light-transmitting state respectively in sequence. When the display state of the electronic device 10 is to provide the display light beam L2 toward the first side A1, the first dimming plate 110 to the fourth dimming plate 170 will be switched to the light-transmitting state, the light-transmitting state, the atomized state and the light-shielding state in sequence. Therefore, the two-way display module 100 can switch the display direction according to the needs or situations to achieve the effect of providing two-way display using a single screen, thereby obtaining a good display experience. In another display state, the first dimming plate 110 and the fourth dimming plate 170 can be further adjusted to the light-transmitting state to form a fully transparent screen or a semi-transparent screen, so as to be applied to augmented reality technology.

In summary, in the bidirectional display module, electronic device, and method for using the electronic device of the present invention, the bidirectional display module is used to provide a display light beam toward at least one of the first side and the second side to switch the display state. The first dimming plate and the fourth dimming plate are used to switch to a light-transmitting state or a light-shielding state according to the display state, and the second dimming plate and the third dimming plate are used to switch to a light-transmitting state or an atomized state according to the display state. Therefore, the bidirectional display module can switch the display direction according to needs or situations to achieve the effect of providing bidirectional display using a single screen, thereby obtaining a good display experience.
