[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0052] Please see Figure 1 , Figure 1 This is a schematic flowchart of a first embodiment of the display method provided in this application. This application provides a display method applied to a display device, which includes a display panel, a 2D backlight, and a 3D backlight. The 2D backlight includes multiple backlight areas. In this embodiment, the display device includes, but is not limited to, mobile phones, tablets, televisions, etc. In this document, a television is used as an example for illustration.

[0053] In 101, if both 2D and 3D signals are received, a first area for displaying the 2D signal and a second area for displaying the 3D signal are determined within the display panel.

[0054] With the development of display technology, 3D display has become a trend. Compared with 2D display, 3D display can bring users an immersive and realistic feeling. At the same time, people still need to display a lot of 2D content. 2D display can conveniently and intuitively display various videos, images, and text information. Therefore, how to present 3D content and 2D content on the same display screen at the same time has become an urgent problem to be solved.

[0055] Display devices, such as televisions, can include multiple input channels, such as HDMI, DP, USB, and streaming media input channels. Different input channels can input different 2D or 3D signals. If any one of the channels receives a 3D signal while another channel receives a 2D signal, then the display device can be considered to be receiving both 2D and 3D signals simultaneously.

[0056] If the display device receives both 2D and 3D signals simultaneously, it is necessary to determine a first area A for displaying 2D signals and a second area B for displaying 3D signals within the display panel.

[0057] In one implementation, this embodiment can preset multiple different display modes, with different arrangements of the first and second regions in each mode. Please refer to... Figures 2 to 4 , Figure 2 This is a schematic diagram illustrating a first display method provided in an embodiment of this application. Figure 3This is a schematic diagram illustrating a second display method provided in an embodiment of this application. Figure 4 This is a schematic diagram illustrating a third display method provided in an embodiment of this application. It should be noted that this embodiment does not limit the arrangement of the first region A and the second region B; for example, they can be arranged horizontally, vertically, or in a picture-in-picture manner. The sizes of the first region A and the second region B can be the same or different.

[0058] For example, a user can select any display mode according to display needs. The display area includes a first area A and a second area B. The display mode can be pre-set so that the first area A is used to display 2D signals and the second area B is used to display 3D signals. Then, when the display device receives both 2D and 3D signals simultaneously, the first area A on the display panel is designated for displaying 2D signals, and the second area B for displaying 3D signals. In another example, the display device can also automatically match a suitable display mode based on parameters such as the format, type, or size of the received 2D and 3D signals. Furthermore, the display device can automatically match suitable areas for displaying 2D and 3D signals respectively, so that the 2D and 3D signals can achieve the best display effect, resulting in a clearer and more complete display with reduced black borders.

[0059] In 102, the 3D backlight is turned on, and at least one backlight area corresponding to the first region in the 2D backlight is turned on, and all backlight areas corresponding to the second region are turned off.

[0060] In 103, the first area is controlled to display 2D signals, and the second area is controlled to display 3D signals.

[0061] For example, the display device may include a display panel, a 2D backlight, and a 3D backlight. The 3D backlight includes a collimated light source and a light guide film. The light guide film includes multiple 3D micro / nano structures with different orientations. The collimated light source can be a side-lit light source located on both sides of the light guide film, capable of providing collimated light to support 3D display. The light emitted by the collimated light source can form light rays in different directions through the 3D micro / nano structures with different orientations.

[0062] The light guide film is located between the display panel and the 2D backlight. The light guide film has a high light transmittance and can transmit the light emitted by the 2D backlight to support the 2D display, so that 2D signals can be displayed in any display area of ​​the display panel.

[0063] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of a 2D backlight provided in an embodiment of this application. In this embodiment, the 2D backlight includes multiple backlight areas, for example, such as... Figure 5As shown, 2D backlighting can adopt local dimming, dividing the 2D backlight into M horizontal blocks and N vertical blocks, for a total of M*N blocks. Each block is a backlight area, and each backlight area can be turned on and off independently, and its brightness can be controlled individually.

[0064] In this embodiment, the display device simultaneously displays 2D and 3D signals, with the first region A used to display the 2D signal. At least one backlight region corresponding to the first region A in the 2D backlight is controlled to be turned on, allowing the turned-on backlight region to emit uniformly diffused light to display the 2D signal. It should be noted that when simultaneously displaying 2D and 3D signals, the 3D backlight needs to be turned on so that the light emitted from the 2D backlight can pass through the light guide film of the 3D backlight. It should also be noted that all backlight regions in the first region A can be turned on, or only partially turned on. For example, if the display area of ​​the first region A is large, but the 2D signal only needs to be displayed in a portion of the area due to parameters such as format, type, or size, then the backlight region of the corresponding area in the first region A can be turned on, thereby saving power consumption of the display device.

[0065] The second area B is used to display 3D signals. Because the light emitted from the collimated light source in the 3D backlight has collimation characteristics, if the 3D backlight and 2D backlight corresponding to the second area B are lit simultaneously, the diffused light emitted from the 2D backlight will disrupt the collimated light emitted from the 3D backlight. Therefore, all backlight areas corresponding to the second area B need to be turned off so that the second area B can display 3D signals normally. Since the backlight area of ​​the 2D backlight can be flexibly turned off and on, this embodiment can also achieve the display of 3D signals in any display area of ​​the display panel.

[0066] The display device also includes a camera that can acquire facial position information, identify and track facial position information in real time, and control the second area B to display 3D signals based on the facial position. Specifically, the display device includes a processor, which may include a CPU, GPU, etc. The processor receives 2D and 3D signals input from different input channels, controls at least one backlight area of ​​the first area A of the display area to turn on for displaying 2D signals; controls the 3D backlight to turn on, and turns off all backlight areas corresponding to the second area B; and controls the second area B to display 3D signals using integrated imaging light field or naked-eye 3D display technology based on the real-time facial position information acquired by the camera.

[0067] Specifically, when using integrated imaging plaza technology to display 3D signals, the light emitted by the collimated light source is formed into light rays in different directions through 3D micro-nano structures with different orientations. Based on the face position information, the pixels of the display panel at the corresponding position are lit up to restore the received 3D signal into a 3D stereoscopic image in front of the face position.

[0068] When naked-eye 3D technology is used to display 3D signals, each frame of the 3D signal includes a left-eye image and a right-eye image. The light emitted by the collimated light source is formed into light rays in different directions through 3D micro-nano structures with different orientations. The position information of the face acquired by the camera also includes the position information of the pupils of the left and right eyes. Based on the position information of the pupils of the left and right eyes, the pixels of the display panel at the corresponding positions are lit up so that the user's left eye sees the left-eye image and the right eye sees the right-eye image. Then, the 3D stereoscopic image is synthesized in the user's brain.

[0069] Because the 2D backlight of the display device includes multiple backlight areas that can be independently turned on and off, all backlight areas in the second area B used for displaying 3D signals can be flexibly turned off according to the display requirements of 3D signals. This ensures that the direction of the collimated light emitted by the 3D backlight is not disrupted by the diffused light emitted by the 2D backlight. This allows for flexible control of the first area A displaying 2D signals and the second area B displaying 3D signals, enabling users to simultaneously view 2D and 3D signals on the same screen. For example, users can watch 3D movies or play 3D games while interacting with 2D content, without interference between the different areas. Furthermore, the diverse ways in which the first area A and the second area B can be divided result in diverse presentation methods for 2D and 3D signals on the same screen, enriching the expressiveness of the display. Users can choose the appropriate presentation method according to different usage scenarios, greatly enhancing the user experience.

[0070] Please refer to Figure 6 , Figure 6 This is a second flowchart illustrating the display method provided in an embodiment of this application.

[0071] In step 201, the first signal of the first input channel and the second signal of the second input channel are acquired.

[0072] In 202, if one of the first signal and the second signal is a 2D signal and the other is a 3D signal, then it is determined that the 2D signal and the 3D signal have been received.

[0073] Display devices, such as televisions, can include multiple input channels, such as HDMI, DP, USB, and streaming media input channels. Different input channels can input different 2D or 3D signals. For example, if one channel inputs a 3D signal and another channel inputs a 2D signal, then the display device can receive both 2D and 3D signals simultaneously.

[0074] It should be noted that at the same time, the display device can simultaneously receive a 2D signal from one input channel and a 3D signal from another input channel, or the display device can simultaneously receive 2D signals from multiple different input channels and a 3D signal from another input channel, or the display device can simultaneously receive 2D signals from multiple different input channels and 3D signals from other different input channels, or the display device can simultaneously receive a 2D signal from one input channel and 3D signals from other different input channels. All of the above situations can be considered as the display device simultaneously receiving 2D and 3D signals.

[0075] In step 203, obtain control commands;

[0076] In step 204, in response to a control command, a first area for displaying 2D signals and a second area for displaying 3D signals are determined within the display panel.

[0077] In one embodiment, multiple different display modes are preset, and the arrangement of the first area A and the second area B is different in the different display modes; in response to a control command, any one of the display modes is determined, and the first area A for displaying 2D signals and the second area B for displaying 3D signals are determined in the display panel according to the display mode.

[0078] For example, users can pre-set different display methods according to different usage scenarios. In different display methods, the arrangement of the first area A and the second area B is different. For example, the first area A and the second area B can be arranged horizontally, vertically, or in a picture-in-picture manner. Therefore, the division of the first area A and the second area B is diversified, giving users more choices.

[0079] The display device can acquire control commands input by the user. These control commands can be used to switch the display device to a common display mode for 2D and 3D signals. The control commands can also be used to determine a first area A for displaying 2D signals and a second area B for displaying 3D signals on the display panel. In other words, the control commands can also be used to select one of the multiple display modes that meets the current display requirements.

[0080] For example, users can input control commands through the user interface displayed on the display panel, or through voice or gestures. Alternatively, if the display device includes a remote control, users can input control commands through the remote control. For instance, users can use preset buttons or shortcut keys on the remote control to control the display device into a shared display mode, displaying multiple display mode options on the user interface. Users can then select one display mode via voice, gestures, or the remote control. Alternatively, users can directly control the display device's user interface to display multiple display mode options via voice, allowing them to select the display mode for a specific area. Furthermore, if the display device detects simultaneous reception of 2D and 3D signals, it can automatically display a prompt asking the user if they want to switch to a shared display mode. If the user selects "yes," the device can automatically match a suitable display mode based on parameters such as the quantity, format, type, and size of the 2D and 3D signals. Of course, users can change to other display modes as needed to achieve a satisfactory display effect.

[0081] In 205, the 3D backlight is turned on, and at least one backlight area corresponding to the first region in the 2D backlight is turned on, and all backlight areas corresponding to the second region are turned off.

[0082] In 206, the first area is controlled to display 2D signals, and the second area is controlled to display 3D signals.

[0083] For example, the display device may include a display panel, a 2D backlight, and a 3D backlight. The 3D backlight includes a collimated light source and a light guide film. The light guide film includes multiple 3D micro / nano structures with different orientations. The collimated light source can be a side-lit light source located on both sides of the light guide film, capable of providing collimated light to support 3D display. The light emitted by the collimated light source can form light rays in different directions through the 3D micro / nano structures with different orientations.

[0084] The light guide film is located between the display panel and the 2D backlight. The light guide film has a high light transmittance and can transmit the light emitted by the 2D backlight to support the 2D display, so that 2D signals can be displayed in any display area of ​​the display panel.

[0085] Please refer to Figure 5 In this embodiment, the 2D backlight includes multiple backlight areas. For example, as shown in the figure, the 2D backlight can adopt the local dimming method, dividing the 2D backlight into M horizontal blocks and N vertical blocks, for a total of M*N blocks. Each block is a backlight area, and each backlight area can be turned on and off independently, and the brightness can be controlled individually.

[0086] In this embodiment, the display device simultaneously displays 2D and 3D signals, with the first region A used to display the 2D signal. At least one backlight region corresponding to the first region A in the 2D backlight is controlled to be turned on, allowing the turned-on backlight region to emit uniformly diffused light to display the 2D signal. It should be noted that when simultaneously displaying 2D and 3D signals, the 3D backlight needs to be turned on so that the light emitted from the 2D backlight can pass through the light guide film of the 3D backlight. It should also be noted that all backlight regions in the first region A can be turned on, or only partially turned on. For example, if the display area of ​​the first region A is large, but the 2D signal only needs to be displayed in a portion of the area due to parameters such as format, type, or size, then the backlight region of the corresponding area in the first region A can be turned on, thereby saving power consumption of the display device.

[0087] The second area B is used to display 3D signals. Because the light emitted from the collimated light source in the 3D backlight has collimation characteristics, if the 3D backlight and 2D backlight corresponding to the second area B are lit simultaneously, the diffused light emitted from the 2D backlight will disrupt the collimated light emitted from the 3D backlight. Therefore, all backlight areas corresponding to the second area B need to be turned off so that the second area B can display 3D signals normally. Since the backlight area of ​​the 2D backlight can be flexibly turned off and on, this embodiment can also achieve the display of 3D signals in any display area of ​​the display panel.

[0088] The display device also includes a camera that can acquire facial position information, identify and track facial position information in real time, and control the second area B to display 3D signals based on the facial position. Specifically, the display device includes a processor, which may include a CPU, GPU, etc. The processor receives 2D and 3D signals input from different input channels, controls at least one backlight area of ​​the first area A of the display area to turn on for displaying 2D signals; controls the 3D backlight to turn on, and turns off all backlight areas corresponding to the second area B; and controls the second area B to display 3D signals using integrated imaging light field or naked-eye 3D display technology based on the real-time facial position information acquired by the camera.

[0089] Specifically, when using integrated imaging plaza technology to display 3D signals, the light emitted by the collimated light source is formed into light rays in different directions through 3D micro-nano structures with different orientations. Based on the face position information, the pixels of the display panel at the corresponding position are lit up to restore the received 3D signal into a 3D stereoscopic image in front of the face position.

[0090] When naked-eye 3D technology is used to display 3D signals, each frame of the 3D signal includes a left-eye image and a right-eye image. The light emitted by the collimated light source is formed into light rays in different directions through 3D micro-nano structures with different orientations. The position information of the face acquired by the camera also includes the position information of the pupils of the left and right eyes. Based on the position information of the pupils of the left and right eyes, the pixels of the display panel at the corresponding positions are lit up so that the user's left eye sees the left-eye image and the right eye sees the right-eye image. Then, the 3D stereoscopic image is synthesized in the user's brain.

[0091] In one embodiment, the first region A includes one or more first sub-regions A1, and / or the second region B includes one or more second sub-regions B1. If the display device receives multiple different 2D signals and one 3D signal, it controls the multiple first sub-regions A1 to display different 2D signals and the second sub-region B1 to display a 3D signal; if multiple different 2D signals and multiple different 3D signals are received, it controls the multiple first sub-regions A1 to display different 2D signals and the multiple second sub-regions B1 to display different 3D signals; if one 2D signal and multiple different 3D signals are received, it controls one first region A to display a 2D signal and the multiple second sub-regions B1 to display different 3D signals.

[0092] That is, in different display methods, the first area A used to display 2D signals may include one or more first sub-areas A1, each of which can display different 2D signals, and the second area B used to display 3D signals may include one or more second sub-areas B1, each of which can display different 3D signals.

[0093] Please refer to Figures 7 to 9 , Figure 7 This is a fourth schematic diagram illustrating the display method provided in the embodiments of this application. Figure 8 This is a fifth schematic diagram illustrating the display method provided in the embodiments of this application. Figure 9 This is a sixth schematic diagram illustrating the display method provided in the embodiments of this application. It should be noted that this embodiment does not limit the number, size, or arrangement of the multiple first sub-regions A1 in the first region A or the multiple second sub-regions B1 in the second region B. The multiple first sub-regions A1 can be adjacent to each other or separated from each other; the multiple second sub-regions B1 can also be adjacent to each other or separated from each other. Therefore, the display methods of one or more first sub-regions A1 and one or more second sub-regions B1 can be diverse and rich, and different sub-regions do not interfere with each other.

[0094] The display device includes multiple input channels. If, simultaneously, the display device receives a 2D signal from one input channel and a 3D signal from another input channel, the display area only needs to display two different signals. Therefore, the selectable display method can be that the display area includes only one first sub-region A1 and one second sub-region B1. Alternatively, if the display device simultaneously receives 2D signals from multiple input channels and a 3D signal from another input channel, the selectable display method can be that the display area includes multiple first sub-regions A1 and one second sub-region B1. Finally, if the display device simultaneously receives 2D signals from multiple input channels and 3D signals from other multiple input channels, the selectable display method can be that the display area includes multiple first sub-regions A1 and multiple second sub-regions B1. At the same time, if the display device receives a 2D signal from one input channel and 3D signals from multiple other input channels, the corresponding display mode can be selected. The display area includes a first sub-region A1 and multiple second sub-regions B1. That is, the user can select a suitable display mode from multiple display modes based on the number of received 2D signals and the number of received 3D signals. Moreover, the distribution of the first sub-region A1 and the second sub-region B1 in each display mode is different, and the user can further select or automatically match a suitable display mode based on the parameters of the display signal.

[0095] It should be noted that the display device may receive only one or more 2D signals at the same time, or only one or more 3D signals at the same time. The display device may also control one or more first sub-regions A1 to display 2D signals, or control one or more second sub-regions B1 to display 3D signals.

[0096] Because the 2D backlight of the display device includes multiple backlight areas that can be independently turned on and off, all backlight areas within the second area B used to display 3D signals can be flexibly turned off according to the display requirements of 3D signals. This ensures that the direction of the collimated light emitted by the 3D backlight is not disrupted by the diffused light emitted by the 2D backlight. As a result, users can simultaneously view two or more different 2D and 3D signals on the same display screen.
