[0043] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0044] The multi-view display control method provided by this application can be applied to Figure 1In the application environment shown, the display device includes a display panel 102, a controller 104, and at least two cameras 106, wherein the controller 104 is connected to the display panel 102 and each camera 106. The camera can be used to detect image data of the current environment. The controller can be used to receive image data transmitted by the camera and process the image data to obtain corresponding human eye information. The controller 104 can also be used to output a normal view angle signal to the display panel when at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is greater than or equal to a preset threshold, so that the display panel displays a normal view angle image; when at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is less than a preset threshold, output a dual view angle signal to the display panel so that the display panel displays a dual view angle image; when only one camera detects human eye information, detect the camera's position information, and output a corresponding directional view angle signal corresponding to the position information to the display panel based on the position information, so that the display panel displays a corresponding directional view angle image corresponding to the corresponding directional view angle signal. The display panel 102 may be, but is not limited to, an AMOLED display panel, an AM Micro LED display panel, an AM Mini LED display panel, or an LCD display panel.
[0045] In one embodiment, Figure 2 As shown, a multi-view display control method is provided, which is applied to Figure 1 The controller 104 in FIG. 1 is used as an example to illustrate the invention, including:
[0046] Step S210: When at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is greater than or equal to a preset threshold, output a normal viewing angle signal to the display panel so that the display panel displays a normal viewing angle picture.
[0047] Among them, the camera can be used to detect image data of the current environment. The camera can be set in the non-display area above the display panel. For example, at least two cameras can be set at intervals in the non-display area above the display panel. Exemplarily, when the number of cameras is 2 (a first camera and a second camera), the first camera is set in the non-display area above the display panel and is set close to the left side of the upper non-display area, and the second camera is set in the non-display area above the display panel and is set close to the right side of the upper non-display area. The display panel is divided into a central display area, a left display area, and a right display area. The camera angle range of the first camera can cover the current environment corresponding to the left display area and the central display area, and then the first camera can be used to detect the current environment image data corresponding to the left display area and the central display area; the camera angle range of the second camera can cover the current environment corresponding to the right display area and the central display area, and then the second camera can be used to detect the current environment image data corresponding to the right display area and the central display area, and then the first camera and the second camera can simultaneously monitor the current environment corresponding to the central display area.
[0048] For example, based on the camera's location and detection range, each camera installed on the display panel can monitor image data of the current environment in real time. Each camera can transmit the detected image data to a controller. The controller can process the received image data and, based on the processing results, determine that the corresponding camera has detected human eye information when the image data contains human eye information. The controller then determines whether at least two cameras have detected human eye information in the same time period. If at least two cameras have detected human eye information in the same time period, the controller extracts features from the person information detected by each camera and compares the extracted features for similarity, thereby obtaining a corresponding feature similarity. The controller can compare the feature similarity with a preset threshold. If the feature similarity of the human eye information detected by each camera is greater than or equal to the preset threshold, the controller determines that a user is currently in the central display area of the corresponding display panel, and that the user's eyes are looking directly at the display panel, while no user is in the left or right display areas. The controller then outputs a front-facing viewing angle signal to the display panel. The display panel is driven by the front-facing viewing angle signal to display a front-facing viewing angle image. This allows the display viewing angle to be switched based on the user's actual location, improving switching flexibility and saving power.
[0049] It should be noted that when the display panel receives the normal viewing angle signal to drive the display, the dual viewing angle display is turned off.
[0050] Step S220 : When at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is less than a preset threshold, a dual-view angle signal is output to the display panel so that the display panel displays a dual-view angle image.
[0051] For example, based on the camera's location and detection range, each camera installed on the display panel can monitor image data of the current environment in real time. Each camera can transmit the detected image data to a controller. The controller can process the received image data and, based on the processing results, determine that the corresponding camera has detected human eye information when the image data contains human eye information. The controller then determines whether at least two cameras have detected human eye information in the same time period. If at least two cameras have detected human eye information in the same time period, the controller extracts features from the person information detected by each camera and compares the extracted features for similarity, thereby obtaining a corresponding feature similarity. The controller can compare the feature similarity with a preset threshold. If the feature similarity of the human eye information detected by each camera is less than the preset threshold, the controller determines that a user is currently in the left display area of the corresponding display panel and that the user's eyes are looking directly at the display panel. Alternatively, if a user is currently in the right display area of the corresponding display panel and that the user's eyes are looking directly at the display panel, the controller outputs a dual-viewing angle signal to the display panel. The display panel is driven by the dual-viewing angle signal to display a dual-viewing angle image. This allows the display angle to be switched based on the user's actual location, improving switching flexibility and saving power.
[0052] It should be noted that when the display panel receives the dual-viewing angle signal to drive the display, the normal-viewing angle display is turned off.
[0053] Step S230, when only one camera detects human eye information, detects the position information of the camera, and outputs a corresponding directional viewing angle signal corresponding to the position information to the display panel based on the position information, so that the display panel displays the corresponding directional viewing angle picture corresponding to the corresponding directional viewing angle signal.
[0054] Exemplarily, based on the camera's setting position and detection range, each camera set on the display panel can monitor the image data of the current environment in real time. Each camera can transmit the detected image data to the controller. The controller can process the received image data and, based on the processing result, determine that the corresponding camera has detected human eye information when the image data contains human eye information. The controller determines whether at least two cameras have detected human eye information in the same time period. If only one camera has detected human eye information in the same time period, the identity information of the camera is extracted, and the location information of the camera is detected. The controller can output a corresponding directional viewing angle signal corresponding to the location information to the display panel based on the location information, so that the display panel displays the corresponding directional viewing angle picture corresponding to the corresponding directional viewing angle signal.
[0055] In one example, the corresponding directional perspective signal includes a left unilateral perspective signal or a right unilateral perspective signal; the corresponding directional perspective picture includes a left unilateral perspective picture corresponding to the left unilateral perspective signal, or a right unilateral perspective picture corresponding to the left unilateral perspective signal.
[0056] For example, if the controller detects human eye information only from the camera located on the left side of the display panel, i.e., this camera is used to detect current environmental image data corresponding to the left and middle display areas, then the controller determines that a user is present in the current environment of the left display area of the display panel. The controller then outputs a left unilateral viewing angle signal to the display panel, causing the display panel to display the left unilateral viewing angle image corresponding to the left unilateral viewing angle signal. It should be noted that when the display panel receives the left unilateral viewing angle signal for driving display, the right unilateral viewing angle display is turned off.
[0057] In another example, if the controller detects human eye information only from the camera located on the right side of the display panel, i.e., this camera is used to detect current environmental image data corresponding to the right and central display areas, then it determines that a user is present in the current environment of the right display area of the display panel. The controller then outputs a right unilateral viewing angle signal to the display panel, causing the display panel to display the right unilateral viewing angle image corresponding to the right unilateral viewing angle signal. It should be noted that when the display panel receives the right unilateral viewing angle signal to drive the display, the left unilateral viewing angle is turned off. This automatically turns off the output signal for a particular side when no one is viewing that side, saving power. Furthermore, the display angle can be automatically switched based on the human eye's perspective, simplifying operation.
[0058] In the above embodiment, when at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is greater than or equal to a preset threshold, a normal view angle signal is output to the display panel so that the display panel displays a normal view angle image; when at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is less than a preset threshold, a dual view angle signal is output to the display panel so that the display panel displays a dual view angle image; when only one camera detects human eye information, the camera's position information is detected and, based on the position information, a corresponding directional view angle signal corresponding to the position information is output to the display panel so that the display panel displays a corresponding directional view angle image corresponding to the corresponding directional view angle signal. This improves the intelligence level of display control, simplifies the display angle switching operation, and reduces power consumption. The present application can automatically switch the display angle according to human eye information. When the human eye is viewing both sides, the output signals of the images on both sides are always on; when no one is viewing a certain side, the output signal of that side is automatically turned off, saving power consumption. The display angle can also be automatically switched according to the human eye's perspective, making operation simpler.
[0059] In one embodiment, Figure 3As shown in Figure 2, the steps for processing human eye information include:
[0060] Step S310: receiving image data transmitted by a camera.
[0061] Among them, the camera can detect the image data of the current environment in real time and transmit the detected image data to the controller.
[0062] Step S320 : performing eye recognition processing on the image data based on an eye tracking algorithm to obtain information about each eye.
[0063] The eye tracking algorithm is pre-loaded into the controller. Based on the eye tracking algorithm, the controller can perform eye recognition processing on the received image data to obtain individual eye information, thereby determining whether the corresponding camera has detected the eye information.
[0064] In one embodiment, Figure 4 As shown, the processing steps of feature similarity include:
[0065] Step S410: Based on the iris recognition algorithm, feature recognition processing is performed on each person's eye information to obtain each feature information.
[0066] The iris recognition algorithm is an algorithm program pre-loaded in the controller. Based on the iris recognition algorithm, the controller can perform feature recognition processing on the processed eye information to obtain feature information, thereby extracting the eye features.
[0067] Step S420: performing comparison processing on each feature information to obtain feature similarity.
[0068] The controller can compare and process each feature information to obtain the feature relativity, and the feature relativity can be used to determine whether the human eye information detected by each camera is the human eye information of the same user.
[0069] In one embodiment, Figure 5 As shown, a multi-view display control method is provided, which is applied to Figure 1 The controller 104 in FIG. 1 is used as an example to illustrate the invention, including:
[0070] Step S510: When at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is greater than or equal to a preset threshold, output a normal viewing angle signal to the display panel so that the display panel displays a normal viewing angle picture.
[0071] Step S520 : When at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is less than a preset threshold, a dual-view angle signal is output to the display panel so that the display panel displays a dual-view angle image.
[0072] Step S530, when only one camera detects human eye information, detects the position information of the camera, and outputs a corresponding directional viewing angle signal corresponding to the position information to the display panel based on the position information, so that the display panel displays the corresponding directional viewing angle picture corresponding to the corresponding directional viewing angle signal.
[0073] Among them, the specific content and process of the above steps S510, S520 and S530 can be referred to the above content and will not be repeated here.
[0074] Step S540 , when no image data transmitted by any camera is received within a preset time, the display screen of the display panel is turned off.
[0075] The controller can monitor in real time whether the cameras are transmitting image data. For example, the controller can include a timing unit that measures the time between the receipt of image data transmitted by the current camera and the next receipt of image data transmitted by the camera. If the controller does not receive image data transmitted by any camera within a preset time, it determines that there is no user in the current environment of the corresponding display panel and turns off the display screen of the display panel, thereby saving power.
[0076] In the above embodiment, the display viewing angle can be automatically switched according to human eye information. When there is a user only in the middle display area of the corresponding display screen, only the front viewing angle screen is turned on; when there are users in the left and right display areas of the corresponding display screen, the output signals of the screens on both sides are always turned on, thereby displaying a dual-viewing angle screen; when no one is watching a certain side, the output signal of the side is automatically turned off, and a single-side viewing angle screen is displayed; when it is detected that there is no user in the current environment of the display panel, all display screens of the display panel are turned off, thereby saving power consumption, and the display viewing angle can be automatically switched according to the human eye viewing angle, and the operation is simpler.
[0077] In one embodiment, Figure 6 As shown, a multi-view display control method is provided, which is applied to Figure 1 The controller 104 in FIG. 1 is used as an example to illustrate the invention, including:
[0078] Step S610: When at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is greater than or equal to a preset threshold, output a normal viewing angle signal to the display panel so that the display panel displays a normal viewing angle picture.
[0079] Step S620 : When at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is less than a preset threshold, a dual-view angle signal is output to the display panel so that the display panel displays a dual-view angle image.
[0080] Step S630, when only one camera detects human eye information, detects the position information of the camera, and outputs a corresponding directional viewing angle signal corresponding to the position information to the display panel based on the position information, so that the display panel displays the corresponding directional viewing angle picture corresponding to the corresponding directional viewing angle signal.
[0081] Among them, the specific content and process of the above steps S610, S620 and S630 can be referred to the above content and will not be repeated here.
[0082] Step S640 , when the image data received within the preset time does not contain the corresponding human eye information, the display screen of the display panel is turned off.
[0083] Among them, the controller can perform human eye recognition processing on the image data transmitted by the camera. When the image data received by the controller within a preset time does not contain corresponding human eye information, it determines that there is no user in the current environment of the corresponding display panel, and then turns off the display screen of the display panel, thereby saving power consumption.
[0084] In the above embodiment, the display viewing angle can be automatically switched according to human eye information. When there is a user only in the middle display area of the corresponding display screen, only the front viewing angle screen is turned on; when there are users in the left and right display areas of the corresponding display screen, the output signals of the screens on both sides are always turned on, thereby displaying a dual-viewing angle screen; when no one is watching a certain side, the output signal of the side is automatically turned off, and a single-side viewing angle screen is displayed; when it is detected that there is no user in the current environment of the display panel, all display screens of the display panel are turned off, thereby saving power consumption, and the display viewing angle can be automatically switched according to the human eye viewing angle, and the operation is simpler.
[0085] It should be understood that although Figure 2-6 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figure 2-6 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.
[0086] In one embodiment, Figure 7 As shown, a multi-viewing angle display control device is provided, comprising:
[0087] The normal viewing angle display unit 710 is configured to output a normal viewing angle signal to the display panel when at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is greater than or equal to a preset threshold, so that the display panel displays a normal viewing angle image;
[0088] The dual-view display unit 720 is configured to output a dual-view signal to the display panel when at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is less than a preset threshold, so that the display panel displays a dual-view image;
[0089] The single-view display unit 730 is used to detect the position information of the camera when only one camera detects human eye information, and output a corresponding directional perspective signal corresponding to the position information to the display panel based on the position information, so that the display panel displays the corresponding directional perspective picture corresponding to the corresponding directional perspective signal.
[0090] For the specific definition of the multi-view display control device, please refer to the definition of the multi-view display control method above, which will not be repeated here. The various modules in the above-mentioned multi-view display control device can be implemented in whole or in part by software, hardware, or a combination thereof. The above-mentioned modules can be embedded in or independent of the controller in the display device in the form of hardware, or can be stored in the memory of the display device in the form of software, so that the controller can call and execute the operations corresponding to the above modules.
[0091] In one embodiment, Figure 8 As shown, a display device is also provided, comprising a display panel 810, at least two cameras 820, and a controller 830; the controller 830 is connected to the display panel 810 and each camera 820. The controller 830 is configured to execute any of the steps of the multi-view display control method described above.
[0092] For example, the controller 830 can be used to perform the following steps: when at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is greater than or equal to a preset threshold, output a normal view angle signal to the display panel so that the display panel displays a normal view angle picture; when at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is less than a preset threshold, output a dual view angle signal to the display panel so that the display panel displays a dual view angle picture; when only one camera detects human eye information, detects the position information of the camera, and outputs a corresponding direction angle signal corresponding to the position information to the display panel based on the position information, so that the display panel displays the corresponding direction angle picture corresponding to the corresponding direction angle signal.
[0093] In one example, the display panel 810 may be, but is not limited to, various AMOLED display panels, AM MicroLED display panels, AM Mini LED display panels, or LCD display panels.
[0094] For example, Figure 9 As shown, when there are two cameras (a first camera and a second camera), the first camera is set in the non-display area above the display panel and is close to the left side of the upper non-display area. The second camera is set in the non-display area above the display panel and is close to the right side of the upper non-display area. The display panel is divided into a central display area, a left display area, and a right display area. The camera angle range of the first camera can cover the current environment corresponding to the left display area and the central display area, and thus the first camera can be used to detect the current environment image data corresponding to the left display area and the central display area; the camera angle range of the second camera can cover the current environment corresponding to the right display area and the central display area, and thus the second camera can be used to detect the current environment image data corresponding to the right display area and the central display area, and thus the first camera and the second camera can simultaneously monitor the current environment corresponding to the central display area.
[0095] In the above embodiment, at least two cameras can be spaced apart in a non-display area above the display panel, and a controller is connected to the display panel and each camera. When at least two cameras detect eye information and the feature similarity of the eye information detected by each camera is greater than or equal to a preset threshold, the controller outputs a normal view angle signal to the display panel, causing the display panel to display a normal view image. When at least two cameras detect eye information and the feature similarity of the eye information detected by each camera is less than a preset threshold, the controller outputs a dual view angle signal to the display panel, causing the display panel to display a dual view image. When only one camera detects eye information, the controller detects the camera's position information and, based on the position information, outputs a corresponding directional view angle signal to the display panel, causing the display panel to display a corresponding directional view angle image corresponding to the corresponding directional view angle signal. This improves the intelligence of display control, simplifies display angle switching operations, and reduces power consumption. The present application can automatically switch the display angle according to eye information. When the user is viewing both sides, the output signals for both sides remain on; when no one is viewing a particular side, the output signal for that side is automatically turned off, saving power. Furthermore, the automatic switching of the display angle according to the user's eye perspective makes operation simpler.
[0096] Those skilled in the art will understand that Figure 8The structure shown in the figure is only a block diagram of a part of the structure related to the scheme of the present application, and does not constitute a limitation on the display device to which the scheme of the present application is applied. The specific display device may include more or fewer components than shown in the figure, or combine certain components, or have a different component arrangement.
[0097] In one example, the display panel includes a first pixel unit and a second pixel unit respectively connected to the controller; when both the first pixel unit and the second pixel unit are lit, a dual-perspective image is displayed; when the first pixel unit or the second pixel unit is lit, a corresponding direction perspective image is displayed.
[0098] For example, when the first pixel unit is lit, the left side single-view picture is displayed; when the second pixel unit is lit, the right side single-view picture is displayed.
[0099] The first pixel unit may include a plurality of sub-pixels arranged in an array; the second pixel unit may include a plurality of sub-pixels arranged in an array. Based on the first pixel unit and the second pixel unit connected to the controller respectively,
[0100] When at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is less than a preset threshold, a dual-view angle signal is output to the display panel, causing the first pixel unit and the second pixel unit to light up respectively, thereby displaying a dual-view image on the display panel. When only one camera detects human eye information, the camera's position information is detected. Based on the position information, if it is determined that the camera located on the left side of the display panel has detected human eye information, a left unilateral view angle signal is output to the display panel, controlling the first pixel unit to light up, so that the display panel displays the left unilateral view image corresponding to the left unilateral view angle signal. If it is determined that the camera located on the right side of the display panel has detected human eye information, a right unilateral view angle signal is output to the display panel, controlling the second pixel unit to light up, so that the display panel displays the right unilateral view image corresponding to the right unilateral view angle signal. This improves the intelligent level of display control, simplifies the display angle switching operation, and reduces power consumption. The present application can automatically switch the display angle according to human eye information. When the human eye is viewing both sides, the output signals of the two images are always on; when no one is viewing a certain side, the output signal of that side is automatically turned off, saving power consumption. The display angle can also be automatically switched according to the human eye's perspective, making operation more simple.
[0101] In one example, when at least two cameras detect human eye information and the feature similarity of the human eye information detected by each camera is greater than or equal to a preset threshold, the controller outputs a normal view angle signal to the display panel, so that the first pixel unit and the second pixel unit are respectively lit up and the display panel displays the normal view angle picture.
[0102] In one example, if Figure 10 As shown, the first pixel unit includes a first sub-pixel, a second sub-pixel, and a third sub-pixel arranged in sequence; the second pixel unit includes a fourth sub-pixel, a fifth sub-pixel, and a sixth sub-pixel arranged in sequence; the luminous color of the first sub-pixel is the same as the luminous color of the fourth sub-pixel, the luminous color of the second sub-pixel is the same as the luminous color of the fifth sub-pixel, and the luminous color of the third sub-pixel is the same as the luminous color of the sixth sub-pixel; the fourth sub-pixel is located between the first sub-pixel and the second pixel, the fifth sub-pixel is located between the second sub-pixel and the third sub-pixel, and the sixth sub-pixel is located between the third sub-pixel and the fourth sub-pixel.
[0103] For example, Figure 10 As shown, the first subpixel may be a red subpixel (R1), the second subpixel may be a green subpixel (G1), the third subpixel may be a blue subpixel (B1), the fourth subpixel may be a red subpixel (R2), the fifth subpixel may be a green subpixel (G2), and the sixth subpixel may be a blue subpixel (B2).
[0104] In the above embodiment, by using the above sub-pixel arrangement rule of the first pixel unit and the second pixel unit, the user can avoid observing black lines when viewing a single-view display, thereby improving the display effect.
[0105] In order to further illustrate the logic control process of the controller, the controller can automatically switch the display angle according to the human eye information, and realize flexible switching of multi-angle display. In an example, Figure 11 As shown, a simulation schematic diagram of a logic control circuit for multi-view display control is provided. The logic control circuit includes a D flip-flop (U12A), a first AND gate device (U1A), a second AND gate device (U4A), a third AND gate device (U11A), a fourth AND gate device (U13A), a first NOT gate device (U1A), a first NOR gate device (U2A), a first switch (S1), a second switch (S2), a third switch (S3), a fourth switch (S4), and a fifth switch (S5).
[0106] Among them, when the left side of the corresponding display panel is unattended and the right side is unattended, the corresponding node a is 0 and the node b is 0; when the left side of the corresponding display panel is watched by someone and the right side is unattended, the corresponding node a is 1 and the node b is 0; when the left side of the corresponding display panel is unattended and the right side is watched by someone, the corresponding node a is 0 and the node b is 1; when the left side of the corresponding display panel is watched by someone and the right side is watched by someone, the corresponding node a is 1 and the node b is 1.
[0107] like Figure 11In the example, when node a is 0 and point b is 0, node A' is 0, node B is 0, and node C is 0; when node a is 0 and point b is 1, node A' is 0, node B is 0, and node C is 1; when node a is 1 and point b is 0, node A' is 1, node B is 0, and node C is 0; when node a is 1 and point b is 1, node A' is 0, node B is 1, and node C is 0.
[0108] The input signal (source) is divided into two by a D flip-flop, and the divided output is ANDed with the original signal to extract the odd and even outputs (VOUT). Figure 12 In the waveform diagram shown, S1 is the original waveform; S2 is when node a is 1 and node b is 0, odd numbers are output and even numbers have no output; S3 is when node a is 0 and point b is 1, even numbers are output and odd numbers have no output; S4 is when node a is 1 and point b is 1, full output.
[0109] By using the above-mentioned logic control circuit, the controller can realize automatic switching of three viewing angles according to the information of the human eye. When the human eye is looking at both sides, the output signals of the pictures on both sides are always on; when no one is looking at a certain side, the output signal of that side is automatically turned off, saving power consumption, and being able to automatically switch the display viewing angle according to the human eye's viewing angle, making operation simpler.
