Detailed ways

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

An electronic device, such as a mobile phone or a tablet computer, generally installs a light sensor to detect the light intensity of the environment where the electronic device is located to automatically adjust the brightness of the screen. Taking a mobile phone as an example, a light sensor is provided on the upper area of the mobile phone. When the user is in the sun or in a dark environment, the light sensor feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions, such as increasing or decreasing the light brightness of the display screen component. In the related art, installing a light sensor on an electronic device requires opening a corresponding hole on the casing to receive an optical signal. However, with the development of electronic devices, people have more and more requirements for the appearance and operation experience of mobile phones high. Mobile phones have been developing in the direction of full-screen, and full-screen mobile phones form an ultra-narrow bezel between the casing and the display component. Because the width of the ultra-narrow bezel is too small, there may not be enough space to open holes, and even opening holes will cause The strength of the frame as a whole is reduced, thereby lowering the reliability of the electronic device.

Please refer to FIG. 1 , an electronic device 100 according to an embodiment of the present invention may be a mobile phone or a tablet computer or the like. The electronic device 100 in the embodiment of the present invention is described by taking a mobile phone as an example. Of course, the specific form of the electronic device 100 may also be other, which is not limited here.

Referring to FIG. 2A , FIG. 2B , FIGS. 3A to 3C and FIGS. 4A to 4C , the electronic device 100 includes a light-transmitting display screen 13 , a light-transmitting cover 11 , a light sensor 16 and a light uniform film 15 .

Wherein, the light-transmitting display screen 13 includes an upper surface 131 and a lower surface 132 , the upper surface 131 and the lower surface 132 are disposed opposite to each other, and the light-transmitting display screen 13 is used for displaying light through the upper surface 131 . The light-transmitting cover plate 11 includes a flat portion 111 and a curved portion 112 extending horizontally and/or vertically along the flat portion 111 and bent. An accommodation space 14 is formed. The light sensor 16 is disposed in the accommodation space 14 , and the light sensor 16 receives visible light through the curved surface 112 . The light uniform film 15 is arranged on the lower surface of the curved portion 112 and covers the light sensor 16 , and the light uniform film 14 is used to increase the angle at which the light sensor 16 receives visible light.

The curved surface 11 of the light-transmitting cover plate 11 extends and bends laterally and/or vertically along the flat plate portion 111. It can be understood that the curved surface 11 of the light-transmitting cover plate 11 can extend transversely and bend along the flat plate portion 111. The light-transmitting cover The curved portion 112 of the board 11 may also extend longitudinally along the flat portion 111 and be bent, and the curved portion 112 of the light-transmitting cover plate 11 may also extend transversely and longitudinally along the flat portion 111 and bend.

When the light sensor 16 receives light of different intensities, it will generate currents of different strengths, thereby sensing the brightness of the ambient light. For example, when the user is under the sun and the ambient light is strong, the light sensor 16 feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to increase the brightness of the display screen to adapt to the light intensity of the current environment. Users watch the content of the screen more clearly. When the user is in a darker environment and the ambient light is weak, the light sensor 16 feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to reduce the brightness of the display screen to adapt to the light intensity of the current environment. The user provides a better visual experience, and saves the power of the mobile phone and can further extend the battery life. Further, when the user is using the camera function, the light sensor 16 can also be used to adjust the white balance. In this way, the light sensor generates detection information from incident light from the outside and transmits it to the processor, and the processor outputs corresponding instructions for control according to the detection information, such as adjusting the brightness of the screen backlight to complete an input and output process.

The light sensor 16 is arranged in the accommodation space 14 formed by the curved surface 112 of the light-transmitting cover plate 11 and the light-transmitting display screen 13, that is, the light sensor 16 can be placed in the accommodation space 14 on the left side of the electronic device 100 or on the side of the electronic device 100. The accommodating space 14 on the right is either located in the accommodating space 14 at the top of the electronic device 100 or in the accommodating space 14 at the bottom of the electronic device 100 .

Further, since the electronic device 100 adopts a curved screen, the light sensor 16 disposed in the accommodating space 14 cannot be completely close to the light-transmitting cover plate 11 and there is a large gap, so that the angle of visible light received by the light sensor 16 is limited. . The homogenizing film 15 contains homogenizing particles, and the homogenizing particles can receive light incident from different directions. Covering the light sensor 16 with the light homogenizing film 15 can increase the angle at which the photo sensor 16 receives visible light.

Please refer to FIG. 1 , the housing 20 is used to accommodate the electronic device 100 to protect the electronic device 100 . By arranging the electronic device 100 in the casing 20 and enclosing the electronic device 100 , it is avoided that external factors cause direct damage to the internal components of the electronic device 100 .

To sum up, the electronic device 100 and the electronic device 100 according to the embodiment of the present invention can arrange the light sensor 16 in the accommodation space 14 formed by the light-transmitting display screen 13 and the light-transmitting cover plate 11 under the condition of realizing a full screen, And through the uniform film 15, the angle at which the light sensor 16 receives ambient light is increased, which not only avoids the traditional hole opening operation, but also ensures the overall strength of the frame area of the electronic device 100 and the good viewing of the external structure, and further improves the electronic device 100. The screen-to-body ratio of the device 100 .

Referring to FIG. 2A and FIG. 3A , in some embodiments, the curved surface 112 includes a window area 1121 , and the light sensor 16 is disposed opposite to the window area 1121 .

Specifically, the light sensor 16 is used to receive visible light. In order to ensure the normal operation of the light sensor 16, it is necessary to set a window area 1121 capable of passing through the visible light on the curved surface 112. The area of the light receiving surface is slightly larger, approximately the same, or smaller.

In such an embodiment, further, the uniform film 15 is attached on the window area 1121 .

Specifically, the light sensor 16 receives external light through the window area 1121 , and the window area 1121 pasted with the uniform film 15 can make the light sensor 16 increase the range of receiving visible light. When performing the attaching process of the light uniform film 15 , the area of the light uniform film 15 may just cover the area of the window area 1121 , or may be larger than the area of the window area 1121 .

Please refer to FIG. 5 and FIG. 3A , further, in such an embodiment, the electronic device 100 further includes a coating layer 19 , and the coating layer 19 is coated on the lower surface of the curved portion 112 and avoids the window area 1121 .

Specifically, the coating layer 19 is used to block visible light, so that other components and metal circuits located under the curved portion 112 of the light-transmitting cover plate 11 are invisible. Since the light sensor 16 is located under the window 1320 of the transparent cover 11 , in order to ensure the normal operation of the light sensor 16 , the window area 1121 is avoided during the process of coating the coating layer 19 . The coating layer 19 can use IR ink, and the transmittance of the IR ink to visible light is less than 6%. Therefore, when the electronic device 100 is viewed from the outside, it cannot be arranged under the curved surface 112 of the light-transmitting cover plate 11 based on the visual observation of the human eye. components and metal lines. The coating layer 19 can also use ordinary black ink, whose light transmittance to visible light is less than 3%, and the shielding effect is more prominent.

In some embodiments, the visible light transmittance of the uniform film 15 is negatively correlated with the increase of the angle at which visible light is received.

Specifically, when a certain amount of homogenizing particles are added to the homogenizing film, these homogenizing particles can refract incident light from different directions multiple times and finally pass through the homogenizing film. Can be received by the light sensor. However, when an excessive amount of homogenizing particles is added to the homogenizing film, the density of the homogenizing particles will be too high, and visible light will not pass through.

In such an embodiment, further, the visible light transmittance of the uniform film 15 is 30%-60%.

Specifically, the light sensor 16 detects by receiving visible light, so it must be ensured that the light sensor 16 can sense the visible light after passing through the light uniform film 15 . On the other hand, the function of the uniform film 15 is to expand the angle at which the light sensor 16 receives visible light. If the light transmittance of the light homogenizing film 15 is set too low for visible light, although the angle at which the light sensor 16 receives visible light is correspondingly increased, the light sensor 16 may not be able to sense the visible light because the intensity of visible light passing through the light homogenizing film 15 is too low. Visible light and cannot maintain normal work. If the light transmittance of the uniform film 15 to visible light is too high, although it is beneficial to the normal operation of the light sensor 16, but because the angle at which the light sensor 16 receives visible light is limited, the light intensity of the current environment cannot be fully judged, resulting in excessive errors. . Therefore, in order to balance the light transmittance and the angle at which the light sensor 16 receives visible light, the visible light transmittance of the uniform film 15 is set to 30%-60%.

Specifically, when no uniform film is provided, the angles at which the light sensor receives light in the negative direction of the X axis and light in the positive direction of the X axis are 50 degrees and 35 degrees respectively, and the angles at which the light sensor receives light in the negative direction of the Y axis and light in the positive direction of the Y axis are 50 degrees and 35 degrees respectively. The angles are 45 degrees and 30 degrees, respectively. In the state of no uniform light film, the light sensor receives light from different angles as a control for comparison.

When the light transmittance of the homogeneous film is set to 25%, the angles at which the light sensor receives the light in the negative direction of the X axis and the light in the positive direction of the X axis are 78 degrees and 65 degrees respectively, and the light sensor receives the light in the negative direction of the Y axis and the light in the positive direction of the Y axis. The angles of the directional rays are 60 and 65 degrees, respectively.

When the light transmittance of the homogeneous film is set to 30%, the angles at which the light sensor receives the light in the negative direction of the X axis and the light in the positive direction of the X axis are 80 degrees and 60 degrees respectively, and the light sensor receives the light in the negative direction of the Y axis and the light in the positive direction of the Y axis. The angles of the directional rays are 60 degrees and 60 degrees, respectively.

When the light transmittance of the homogeneous film is set to 50%, the angles at which the light sensor receives the light in the negative direction of the X axis and the light in the positive direction of the X axis are 65 degrees and 30 degrees respectively, and the light sensor receives the light in the negative direction of the Y axis and the light in the positive direction of the Y axis. The angles of the directional rays are 55 degrees and 50 degrees, respectively.

When the light transmittance of the homogeneous film is set to 75%, the angles at which the light sensor receives the light in the negative direction of the X axis and the light in the positive direction of the X axis are 55 degrees and 35 degrees respectively, and the light sensor receives the light in the negative direction of the Y axis and the light in the positive direction of the Y axis. The angles of the directional rays are 43 degrees and 35 degrees, respectively.

Please refer to FIG. 4A to FIG. 4C , in some embodiments, the light-transmitting display screen 13 includes a display panel portion 1312 .

Specifically, the display panel portion 1312 is used to display content effects, and this area may be straight.

Please refer to FIG. 5 , in some embodiments, the light-transmitting display screen 13 includes a display flat portion 1312 and a display curved portion 1313 extending horizontally and/or vertically along the display flat portion 1312 , and the upper surface of the display flat portion 1312 and the display curved surface The upper surfaces of the portions 1313 jointly constitute the upper surface 131 of the light-transmitting display screen 13 , and the lateral dimension of the light-transmitting cover plate 11 is larger than that of the light-transmitting display screen 13 .

Specifically, by setting the display curved surface 1313 extending horizontally and/or vertically on the light-transmitting display screen 13, the shape of the light-transmitting display screen 13 and the light-transmitting cover 11 can be more matched, which is beneficial to the shape of the light-transmitting display screen 13 and the light-transmitting cover. The fit of the board 11 is tighter. That is, when the curved surface 112 of the light-transmitting cover 11 extends laterally along the flat portion 111 and bends, the display area surface 1313 of the light-transmitting display 13 extends laterally along the display flat portion 1312 . When the curved surface 112 of the light-transmitting cover 11 extends longitudinally along the flat portion 111 and bends, the display area surface 1313 of the light-transmitting display 13 extends longitudinally along the display flat portion 1312 . When the curved surface 112 of the light-transmitting cover 11 extends horizontally and vertically along the flat portion 111 and is bent, the display area surface 1313 of the light-transmitting display 13 extends horizontally and vertically along the display flat portion 1312 . Setting the translucent cover 11 to have a lateral dimension larger than that of the translucent display 13 can effectively protect the translucent display 13 and its internal structure, and avoid direct damage to the translucent display 13 by external forces.

Please refer to FIG. 6 , in some embodiments, the light-transmissive display screen 13 includes an OLED display screen.

Specifically, an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display screen has good light transmittance and can transmit visible light. Therefore, the OLED display does not affect the light received by the light sensor when displaying content effects. The OELD display screen has the property of being bendable, so it can be made into a curved screen, so as to provide users with better visual effects, that is to say, the light-transmitting display screen 13 can be a curved screen. The light-transmitting display screen 13 may also adopt a Micro LED display screen, and the Micro LED display screen also has a good light transmittance to visible light. Of course, these display screens are only exemplary and the embodiments of the present invention are not limited thereto.

Please refer to FIG. 7 , in some embodiments, the electronic device 100 further includes a light-transmitting touch panel 12 . The light-transmitting touch panel 12 is arranged on the light-transmitting display screen 13, the upper surface 131 of the light-transmitting display screen 13 faces the light-transmitting touch panel 12, and the light transmittance of the light-transmitting touch panel 12 and the light-transmitting cover plate 11 to visible light Greater than 90%.

Specifically, the light-transmitting touch panel 12 is mainly used to receive the input signal generated when the user touches the light-transmitting touch panel 12 and transmit it to the circuit board for data processing, so as to obtain the specific information of the user touching the light-transmitting touch panel 12. Location. Wherein, the light-transmitting touch panel 12 and the light-transmitting display screen 13 can be bonded by using In-Cell or On-Cell bonding technology, which can effectively reduce the weight of the display screen and reduce the overall thickness of the display screen. In addition, the light-transmitting cover plate 11 is arranged on the light-transmitting touch panel 12, which can effectively protect the light-transmitting touch panel 12 and its internal structure, and avoid external force from affecting the light-transmitting touch panel 12 and the light-transmitting display screen. 13 damage. The light transmittance of the light-transmitting cover plate 11 and the light-transmitting touch panel 12 to visible light is greater than 90%, which is conducive to the light-transmitting display screen 13 to better display the content effect, and can also ensure that the light sensor 16 can normally receive light. .

Please refer to FIG. 4 and FIG. 7 , in some embodiments, the upper surface 131 includes a display area 1311 , and the light-transmitting display screen 13 is used to display light through the display area 1311 . The ratio is greater than 90%.

Specifically, by setting the ratio of the display area 1311 to the light-transmitting cover 11, after the light-transmitting display screen 13 is pasted by the light-transmitting cover 11, the display area 1311 can display the content effect with a larger size area, which not only improves This not only ensures a good user experience, but also effectively increases the screen-to-body ratio of the electronic device 100 to achieve a full-screen effect. The area of the upper surface 131 other than the display area 1311 can also be used to cover other components and metal circuits located under the light-transmitting display screen 13, so that the appearance of the product remains consistent. The areas other than the display area 1311 can be printed with ink to enhance the optical density of the light-transmitting display screen 13 , which can create a good visual effect while ensuring the light-shielding effect.

In some embodiments, the light sensor 16 includes an ambient light sensor, and the ambient light sensor is used to sense ambient brightness to adjust the brightness of the light-transmitting display screen 13 .

Specifically, when the user is in the sun and the ambient light is strong, the ambient light receiver feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to increase the brightness of the display screen to adapt to the light intensity of the current environment. , so that users can see the content of the screen more clearly. When the user is in a dark environment and the surrounding light is weak, the ambient light receiver will feed back the light intensity of the current environment to the processor, and the processor will execute corresponding instructions to reduce the brightness of the display screen to adapt to the light intensity of the current environment. Provide users with a better visual experience. In this way, it is not only beneficial to protect the eyesight of the user, but also saves the power of the mobile phone and can further achieve the effect of prolonging the battery life.

The buffer layer 17 can be made of foam or foam plastic or rubber or other soft materials. Of course, these cushioning materials are only exemplary and the embodiments of the present invention are not limited thereto. Further, in order to prevent the buffer layer 17 from blocking the optical signal path between the light uniform film 15 and the light sensor 16, the light uniform film 15 and the light sensor 16 are avoided during the process of setting the buffer layer 17, so as to prevent the light sensor 16 from receiving visible light. affected.
