Detailed ways

In order to make the above objects, features and advantages of the present invention more comprehensible, a preferred embodiment will be described in detail below together with the accompanying drawings.

FIG. 1A is a functional block diagram showing a display system according to an embodiment of the invention. FIG. 1B is a schematic diagram showing images formed by the light passing through the display panel in the eyes of the user according to an embodiment of the present invention. As shown in FIG. 1A , the display system 100 includes a display panel 110 and a video processing unit 120 , wherein the display panel 110 is composed of a white organic light emitting diode (WOLED) array, for example. In one embodiment, the display panel 110 includes a color filter layer 111 , a lens layer 112 , a white organic light emitting diode array (WOLED Array) 113 and a driving circuit 114 . The color filter layer 111 is the uppermost layer of the display panel 110 , which means it is closest to the user, and is used to form colors, such as RGB or RGBW. In other words, the light passing through the lens layer 112 passes through the color filter layer 112 and enters the user's eyes. The lens layer 112 is used to direct light from different light groups in the white OLED array 113 to different directions (details will be described later), as shown in FIG. 1B . The white organic light emitting diode array 113 includes a plurality of white light diode groups regularly arranged, and with the design of the lens layer, a corresponding light group arrangement will be generated, wherein the brightness and darkness of each white light diode can be adjusted. For example, the light groups are vertical strips or oblique straight strips, and there must be a plurality of light groups (for example, at least 2 groups) in a periodic and symmetrical arrangement. It should be noted that, in the embodiments of the present invention, for ease of description, the number of light groups is taken as 4 groups, 6 groups or 8 groups as an example. Those skilled in the field of the present invention should understand that the number of light groups in the present invention is not limited thereto. The driving circuit 114 is used to control the light emission of each white light diode (including sub-pixels such as R/G/B/W) in the white light organic light emitting diode array 113 .

The video processing unit 120 is used for receiving a complex video signal (for example, a multi-view video signal) or a video signal generally having only a single frame, and converting the video signal into a complex video signal. Next, the video processing unit 120 also converts the complex image signal into a corresponding light group control signal. The light group control signal can control the corresponding groups in the white organic light emitting diode array to emit light (that is, to emit rays).

In FIG. 1B, each pixel has a corresponding color (for example, R/G/B/W) in the color filter layer 111, which is composed of color filters of different colors, such as red A filter 1111 , a green filter 1112 , a blue filter 1113 , and a white filter 1114 . For example, each set of red filters 1111 , green filters 1112 , blue filters 1113 , and white filters 1114 arranged in sequence can be called a “pixel filter set”. It should be noted that each color has a corresponding light group in the white OLED array 113 , and the positions marked with 1, 2, 3, and 4 indicate the number of the light group to which the sub-pixel belongs. When the video processor 121 controls a certain light group to display, for example, light group 1, the sub-pixels representing light group number 1 will emit light in sequence, and the emitted light will be refracted by the lens layer to pass through the color filter layer Filters of the corresponding color and reach the user's eyes for imaging.

FIG. 2A is a schematic diagram showing distribution of light to different viewing angles by a display system according to an embodiment of the present invention. As shown in FIG. 2A, the white organic light emitting diode array 113 has four different light groups 1-4, and the video processing unit 120 will convert the received video signal into a corresponding complex image signal, and generate corresponding four light groups. group control signal. FIG. 2B and FIG. 2C are schematic diagrams showing the matching of the lens layer and the white OLED array according to an embodiment of the present invention. As shown in FIG. 2B , taking RGB imaging as an example, each pixel of a white LED in the white OLED array 113 is composed of red, green and blue sub-pixels, for example, FIG. 2B and FIG. 2C The sub-pixels 202, 204 and 206 in . When the lens layer 212 is in the shape of vertical stripes, it means that light enters from a direction completely perpendicular to the lens layer 212 , and at this time the sub-pixels 202 - 206 can be aligned, as shown in FIG. 2B . When the lens layer 212 is in the shape of oblique stripes, it means that light enters from a direction that forms a fixed angle with the lens layer 212. At this time, the arrangement of the sub-pixels 202-206 also needs to be consistent with the angle of the lens layer 212, as shown in FIG. 2C Show. Furthermore, the aforementioned four light group control signals are to control the white light organic light emitting diodes with corresponding numbers (that is, the light group) in FIG. 2B or FIG. 2C to emit light.

FIG. 3A is a schematic diagram showing the connection relationship between the white OLED array 113 and the driving circuit 114 according to an embodiment of the present invention. In one embodiment, the driving circuit 114 includes a source driver circuit (source driver) 1141 and a gate driver circuit (gate driver) 1142 . The brightness and darkness of each sub-pixel in the white OLED array 113 can be controlled by the source driving circuit 1141 and the gate driving circuit 1142 . For example, the voltages VDD and GND are supplied to the source driving circuit 1141 and the gate driving circuit 1142, and the source driving circuit 1141 and the gate driving circuit 1142 are used to receive the optical group control signal and The corresponding video signal is converted into a selection signal for each of the white OLEDs in the white OLED array 113 to further control the brightness of each of the white OLEDs.

FIG. 3B is a circuit diagram showing a sub-pixel according to an embodiment of the invention. FIG. 3C is a schematic diagram showing a source driving circuit according to an embodiment of the invention. As shown in FIG. 3C , each sub-pixel (eg, R/G/B) has a corresponding light group. When the source driving circuit 1141 receives the photogroup signal, the source driver circuit 1141 converts the photogroup signal into a corresponding photogroup control signal of the white OLED. For example, if the video processing unit 120 is only set to view light groups 1 and 3, the source driver circuit 1141 will still be able to drive the first pixel of the first line in the white organic light emitting diode array 113. According to the order of sequential scanning (for example, the sub-pixels of light group 1 are turned on first, and then the sub-pixels of light group 3 are turned on) to control the lightness and darkness of the white OLEDs. It should be noted that the light group signal sent by the video processing unit 120 can designate a pixel to be completely black or a certain specific light group to be completely black, or the source driving circuit 1141 and the gate driving circuit 1142 will turn on the light when it is time to When grouping, no opening voltage is given. Furthermore, when driving the first pixel of the first line in the white organic light emitting diode array 113, the light group signals sent by the video processing unit 120 can control the light groups 1, 2, 3, and 4 in sequence. glowing. If a certain light group is not turned on, the corresponding sub-pixel of the light group is controlled to be off (that is, completely black), wherein the sub-pixel circuit 300 is shown in FIG. 3B . In FIG. 3B , the transistors M1 , M2 and the OLED L1 in the sub-pixel circuit 300 are controlled by the video signal line from the source driver circuit 1141 and the gate and selection lines from the gate driver circuit. Those skilled in the art of the present invention should be able to understand the operation of known sub-pixel circuits, so the details will not be repeated here.

FIG. 4A is a functional block diagram showing a source driving circuit according to an embodiment of the invention. In one embodiment, the design of the source driving circuit 1141 allows the sub-pixels in different light groups to be independently controlled, that is, each group's shift register, sampler (sampling unit), data latch A data latch and a buffer can correspond to multiple sub-pixels (such as R/G/B sub-pixels) of the same optical group, wherein the storage/reading unit receives a clock signal. It should be noted that the source driver circuit 1141 still sequentially controls the light groups and their sub-pixels in each pixel along a horizontal scanning line in a sequential scanning order (that is, from left to right, from top to bottom) .

FIG. 4B is a functional block diagram showing a source driving circuit according to another embodiment of the present invention. In another embodiment, the difference between FIG. 4B and FIG. 4A is that when the source driver circuit 1141 outputs to the white light organic light emitting diode array 113, it first passes through a one-to-two decoder (De-multiplexer), and then is controlled into right pixel. It should be noted that the above-mentioned decoder is located between the source driving circuit 1141 and the white OLED array 113 . Furthermore, the group control signal for controlling the white OLED array 113 can be implemented inside the source driving circuit 1141 (as shown in FIG. 4A ) or externally (as shown in FIG. 4B ).

It should be noted that each light group in the white OLED array 113 can not only support a general two-dimensional image, but also support a stereoscopic image/three-dimensional image. Utilizing the light group design of the present invention, the light can be effectively used, and the light also has directionality, and the light group at an angle that is not used does not need to emit light, which can save power. In addition, the directional light source can also be used for anti-peeping, or provide the same or different stereoscopic images to one or more users in different positions.

FIG. 5A is a functional block diagram showing the video processing unit 120 according to an embodiment of the invention. In one embodiment, the video processing unit 120 includes a video processor 121 and a memory unit 122 , as shown in FIG. 5A . The video processor 121 is, for example, a central processing unit (CPU) or a digital signal processor (DSP), and the memory unit 122 is, for example, a random access memory (such as SRAM or DRAM, etc.). The video processor 121 receives a video signal and stores the video signal in the memory unit 122, wherein the video signal can be a two-dimensional image from a general single viewing angle, a stereoscopic image (left-eye image and corresponding right-eye image), Or a video signal composed of multi-view images (which may be two-dimensional images or stereoscopic images). When the received video signal is to be played on the display system 100, the video processor 121 first analyzes the image format of the video signal, and according to at least one display setting of the display system 100 (for example, at which angles to watch, whether it is Stereo image or multi-view image, etc.) to adjust the output light group signal. Furthermore, the video processor 121 marks a view tag (viewtag) on the corresponding light group according to the display setting of the display system 100 . Therefore, when the video processor 121 reads the frames of the video signal from the memory unit 122 , it can decide to output those frames to the corresponding light group according to the ornamental tag of the light group.

FIG. 5B is a schematic diagram showing light groups and their corresponding viewing angle labels in different display modes according to an embodiment of the invention. For example, in one embodiment, if the video signal received by the display system 100 is only composed of general two-dimensional images I, the video processor 121 can give corresponding The light group-viewing label, and then activate (activate) the corresponding light group and transmit the corresponding picture in the video signal to the corresponding light group for playing. For example, in the center first-light group 4 mode, only the white OLEDs in the light group 4 are turned on, which is marked as A in FIG. 5B . In the max view mode, light groups 1 to 4 will be marked with corresponding viewing labels, for example, "Al" means to turn on the left eye image, "Ar" means to turn on the right eye image, and "off" means to turn on the right eye image. Indicates that the light group is turned off. In other words, in the maximum viewing area mode, light groups 1-4 are all turned on.

In another embodiment, if the video signal received by the display system 100 is a stereoscopic video, it is composed of a plurality of left-eye images and right-eye images. However, each light group in the white OLED array 113 can only display a single two-dimensional image. Therefore, if the white OLED array 113 is to be used to display a stereoscopic image, at least two adjacent light groups need to be used. For example, as shown in Figure 5B, in the center priority-light group 2/3 mode, both light group 2 and light group 3 will be marked with ornamental tags, wherein light group 2 is used to display the image for the left eye, and light group 3 is used to display the image for the right eye, while light group 1 and light group 4 are both turned off. Please refer to FIG. 2A again. It should be noted that the user needs to be at the junction of the light ranges of light group 2 and light group 3 (such as positions 210 and 220) to correctly view the stereoscopic image, which means that the left eye image needs to be projected to The user's left and right eye images need to be projected to the user's right eye. In the maximum viewing area mode, light groups 1 to 4 will be turned on, of which light groups 1 and 3 are used to display images for the right eye, and light groups 2 and 4 are used to display images for the right eye. It should be noted that when the display system 100 plays a stereoscopic video, the range angle of the light emitted by each light group is limited, and the left eye/right eye image must be correctly projected to the user's left eye/right eye, so The user needs to select a specific angle to view the stereoscopic video correctly. In addition, in FIG. 5B , each viewing mode under the same video signal can be switched arbitrarily, and the video processor 121 can independently control whether each light group is turned on and the image to be played when turned on.

Furthermore, when the received video signal is to be played on the display system 100, the video processor 121 first analyzes the format of the received video signal, and adjusts the output video signal according to the display setting of the display system 100. light group signal. In one embodiment, if the video signal is composed of two-dimensional images with a single viewing angle, the video processor 121 can decide whether to copy the video signal to the light groups to be displayed according to the display settings of the display system 100 . For example, if the display setting of the display system 100 is to turn on light group 2 and light group 4, when the video processor 121 determines that the received video signal is composed of a two-dimensional image with a single viewing angle, the video processor 121 can set the The video signal is transmitted to light group 2 and light group 4 at the same time. If the display is set to the maximum viewing area mode, the video processor 121 can transmit the video signal to the light groups 1-4 at the same time.

In another embodiment, when the video processor 121 determines that the received video signal is composed of multi-view images (that is, the image frames of different viewing angles are independent), the video processor 121 can display the video signal according to the display settings. The images of different viewing angles in the signal are delivered to the specified light group. For example, if the video signal includes a plurality of first-view images, second-view images, and third-view images, the video processor 121 may transmit the first-view images, second-view images, and third-view images to the optical Group 2, Light Group 3 and Light Group 4. The video processor 121 may also transmit the first perspective image and the second perspective image to the light group 3 and the light group 2 respectively. In other words, the video processor 121 can designate light groups to display images of different viewing angles in the video signal, and can also control whether to display each viewing angle in the video signal of the multi-view image.

FIG. 6A is a functional block diagram showing a display system according to another embodiment of the present invention. FIG. 6B is a schematic diagram showing the corresponding relationship between a user's position and the visible area of the light group to display a two-dimensional image according to an embodiment of the present invention. In another embodiment, as shown in FIG. 6A , the display system 100 can also include an image extraction unit 150 for extracting the user's face image, and the video processor 121 can also analyze the image extracted by the image extraction unit 150. The face image is used to detect the position of the user's eyes, and then according to the detected position of the user's eyes, it is judged that the user is in the visible area to which light groups belong. This method can also be called user visual position detection. Therefore, the video processor 121 can transmit the corresponding light group control signal (for example, the light group control signal to turn on only the light group 4) to the white organic light emitting diode array 113 according to the user's position (such as the position L1 in FIG. 6B ). , so as to turn on the corresponding light groups in the white OLED array 113 . Furthermore, when the user moves the location, the video processor 121 can detect the location where the user moves from the extracted face image (for example, moving from location L1 to location L2 in Figure 6C), and then based on the detected The position of the user determines the light group to which he belongs (such as light group 4), and then generates a corresponding light group control signal (such as a light group control signal that only turns on light group 4) to the white light organic light emitting diode array 113 to control the corresponding light group to display.

6C is a schematic diagram showing the corresponding relationship between the position of a single user and the visible area of the light group to display a two-dimensional image according to another embodiment of the present invention. In one embodiment, the display system 100 can use the image extraction unit 150 to extract the face image of the user, and the video processor 121 can also analyze the face image extracted by the image extraction unit 150 to detect whether the position of the user's eyes is Move, and determine that the position moved by the user's eyes is in the visible area to which those light groups belong. When detecting the visible area of the light group moved by the user's eyes (for example, position L1 in FIG. 6C moves to position L2), the video processor 121 can generate a corresponding light group control signal (such as light group 1), meaning That is, only light group 1 of the white OLED array 113 is turned on to display images.

FIG. 6D is a schematic diagram showing a stereoscopic image displayed by detecting the corresponding relationship between the positions of multiple users and the visible areas of the light groups according to another embodiment of the present invention. As shown in FIG. 6D , when the display system 100 detects that the position of user A is in the visible area of light group 4, and the position of user B is in the visible area of light group 2, the video processor 121 will generate corresponding light The group control signal is sent to the white OLED array 113 to turn on the light group 4 and the light group 2 . It should be noted that the images played by the light group 4 and the light group 2 may be different, and the display settings and user settings of the display system 100 shall prevail. If the input video signal is only a single picture, light group 4 and light group 2 can play the same picture. If the input video signal is a multi-view image, the light group 4 and the light group 2 can choose to play the same or different view images. It should be noted that whether the other light groups except the light group 4 and the light group 2 are turned on or not depends on the display setting of the display system 100 or the user setting.

FIG. 6E is a schematic diagram showing the corresponding relationship between the positions of multiple users and the visible areas of the light groups to display a stereoscopic image according to another embodiment of the present invention. In another embodiment, if the user wants to view a stereoscopic image on the display system 100 , his left eye and right eye need to receive the correct left-eye image and right-eye image respectively to form a correct stereoscopic image. The display system 100 can also use the face image extracted by the image extraction unit 150 to detect that the position of the user's eyes is in the visible area of which light group, and then generate corresponding light group control signals to different light groups, so as to play Left eye image or right eye image. For example, as shown in FIG. 6E , the display system 100 detects that the left eye and the right eye of user A are in the visible areas of light group 2 and light group 1 respectively, and the input video signal is a stereoscopic image, so the video The processor 121 generates corresponding light group control signals to the white organic light emitting diode array 113, so as to control the light group 2 to play the left-eye image (marked as L in the corresponding light group 2), and control the light group 1 to play the right-eye image ( Indicated as R in the corresponding light group 1). It should be noted that whether the other light groups except the light group 2 and the light group 1 are turned on depends on the display setting of the display system 100 or the user setting.

FIG. 6F is a schematic diagram showing the corresponding relationship between the positions of multiple users and the visible areas of the light groups according to yet another embodiment of the present invention. In yet another embodiment, the display system 100 can also detect the position moved by the user, and determine that the positions moved by the user's eyes are respectively in the visible area of which light group. As shown in Figure 6F, the user is originally at position L5. If the user moves to position L6, the display system 100 can detect that when the user is at position L6, the left and right eyes of the user are located in light group 3 and light group respectively. 2, the video processor 121 generates a corresponding light group control signal to the white organic light emitting diode array 113, so as to control the light group 3 to play the image for the left eye, and control the light group 2 to play the image for the right eye. If the user moves to the position L7, then the display system 100 can detect that when the user is at the position L7, the left eye and the right eye of the user are also respectively located in the visible areas of the light group 3 and the light group 2, so the video processor 121 A corresponding light group control signal is generated to the white OLED array 113 to control the light group 3 to play the left-eye image, and control the light group 2 to play the right-eye image. It should be noted that when the user moves to the position L6 or L7, whether other light groups except the light group 3 and the light group 2 are turned on depends on the display setting of the display system 100 or the user setting.

FIG. 6G is a schematic diagram showing the corresponding relationship between the detected positions of multiple users and the visible areas of the light groups according to yet another embodiment of the present invention. In yet another embodiment, the display system 100 can also detect the positions of the eyes of multiple users, and determine that the left and right eyes of the users are respectively located in the visible areas of those light groups. For example, as shown in FIG. 6G , the display system 100 detects that the left eye and right eye of user A are located in the visible areas of light group 2 and light group 1 respectively, and the left eye and right eye of user B are respectively Located in the visible area of light group 4 and light group 3. The video processor 121 generates corresponding light group control signals to the white OLED array 113 to control light groups 2 and 4 to play left-eye images, and control light groups 1 and 3 to play right-eye images. It should be noted that if the input video signal is a multi-view stereoscopic image, user A and user B can be set to view stereoscopic images of the same viewing angle or different viewing angles. This depends on the display settings of the display system 100 and User settings prevail. In addition, if the light groups where the eyes of different users are located will cause conflicts when displaying stereoscopic images, the user needs to fine-tune their positions so that the display system can detect the user's moving position and then adjust the corresponding light groups Control signal, at this time the user can watch the correct stereoscopic image.

FIG. 7 is a flow chart showing an image display method according to an embodiment of the invention. In step S710, the display system 100 receives a video signal. In step S720, the video processor 121 analyzes an image format of the video signal. It should be noted that the video signal can be a single-view 2D image or a stereoscopic image, or a multi-view 2D image or a stereoscopic image.
