[0002] In actual applications of display devices, the display area can be divided into multiple independent display sub-areas, and the signals of one or more connected data sources can be distributed to different display sub-areas, so that each display sub-area can independently display different data source content. It has been widely used in situations such as security monitoring, education, office scenes, game entertainment or financial transactions, etc., which require the simultaneous display of multiple information sources or applications.

The embodiments of the present application are described below in conjunction with the drawings. It is known to those of ordinary skill in the art that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application.

[0053] In order to solve the above problems, an embodiment of the present application provides a display device. The display device of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0054] Reference Figure 1 , is a schematic diagram of the structure of a display device provided in Embodiment 1 of the present application, such as Figure 1 As shown, the display device can be a laptop, a tablet computer, a monitor or a desktop computer, etc. Figure 1 As shown, the display device may include: a communication port 110, a display device 120 and a processing device 130, wherein:

[0055] The communication port 110 can be used to obtain display data to be output, such as image data, text data, video data, etc. The display data can come from a local storage device, or a server or other terminal device, etc., and can be determined according to the display data source in the actual application scenario. In addition, the display data to be output can come from a display data source, and the display data in the data display format supported by the display device is obtained by parsing the transmission signal of the display data source; it can also come from different display data sources, and the display data in the data display format supported by the display device is obtained by processing the transmission signals of each display data source. This application does not limit the source of the display data to be output and the data display format.

[0056] In actual applications, the communication port 110 can be implemented through one or more wireless communication methods such as WiFi (wireless fidelity), Bluetooth, near field communication, GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), Long Term Evolution (LTE), email, short messaging service (SMS), etc.

[0057] The communication port 110 may also include a general-purpose input / output (GPIO) interface, a USB interface, a universal asynchronous receiver / transmitter (UART) interface, DP (DisplayPort, a digital video interface standard developed by a PC and chip manufacturer alliance and standardized by the Video Electronics Standards Association), HDMI: High Definition Multimedia Interface, which is a fully digital video and sound transmission interface that can send uncompressed audio and video signals, a PCIe (peripheral component interconnect express, a high-speed serial computer expansion bus standard) interface or other serial / parallel ports and other one or more wired communication methods to connect to the corresponding display data source, receive signals sent by the display data source or display data to be output, etc. The present application does not limit the number and type of the communication port 110.

[0058] Exemplarily, the communication port 110 can be connected to an electronic device such as a data cable or any of the above-mentioned wireless communication methods, obtain an image signal that can be continuously output on the display device from the graphics card or display interface of the electronic device, and process the image signal to generate image data that can be output in the display area of ​​the display device, that is, the image data to be output. The processing process is not described in detail in this application.

[0059] The display device 120 may be configured to output different display data in the at least two display sub-regions respectively when the display region is divided into at least two display sub-regions.

[0060] In the embodiment of the present application, the display area of ​​the display device 120 is divided into at least two display sub-areas, which can represent a true split screen mode, that is, a screen display function implemented by hardware equipment or technology, so that each display sub-area can output different display data, which can be different display data from the same display data source, such as processing the signal from the display data source, splitting the obtained one-way display data into multiple-way display data, and controlling them to be displayed in different display sub-areas. Of course, the display data output by different display sub-areas can also come from different display data sources. The present application does not limit the source of the different display data output by each display sub-area itself and the processing and acquisition method thereof, which can be determined according to the actual scene requirements.

[0061] Among them, the present application divides the display area (global display area) of the display device 120 into at least two display sub-areas. It does not divide the display area of ​​the display device 120 (such as a display screen) into various display sub-areas in hardware, but simulates corresponding multiple displays inside the display device 120, so that each of the divided display sub-areas can be recognized as a plurality of independent displays by the electronic device connected to the display device, and can be distinguished and identified by each display sub-area having a unique display identifier, so that the display data sent to the display device that needs to be output independently by each display sub-area can be independently controlled without affecting each other.

[0062] Moreover, since each display sub-area of ​​the present application is equivalent to a display simulated by a display device, in a scenario where split-screen display is required, data processing can be performed according to the pre-configured processing logic and the configuration information provided by the display device. No software driver is required on the electronic device side, and no special requirements are required for the operation of the electronic device. This makes the present application not restricted by the application program, and there are no compatibility issues. It has strong applicability and is more convenient to use.

[0063] In actual applications, for the trigger control method of the above-mentioned hard split-screen method, a corresponding split-screen instruction can be generated by pressing a physical button deployed in the display device, or by inputting a matching voice command, or by detecting the current working state or display mode of the display device, etc., to instruct the display area of ​​the display device 120 to be divided into at least two display sub-areas. The size of each display sub-area, as well as the size ratio and position relationship between them, can be customized or dynamically adjusted according to the actual scene requirements, and the implementation process is not described in detail in this application.

[0064] Based on this, before the display device turns on the hard split screen mode, its display area is still a complete display area. The display data to be output obtained by the communication port 110 can be directly output in the display area. In this case, if the display device is connected to two or more electronic devices, that is, multiple display data sources are connected, the display data to be output of each of the multiple display data sources can be merged, and the merged display data can be output in the display area.

[0065] In an embodiment of the present application, the display device 120 may include one or more display screens. The display area of ​​each display screen may be divided into multiple display sub-areas according to the method proposed in the present application, so as to implement the processing method proposed in the present application.

[0066] The processing device 130 can be used to obtain a display mode control instruction, determine a target display sub-area in the at least two display sub-areas that matches the display mode control instruction, control the target display sub-area to be in a first display mode so that the display data output by the target display sub-area presents a first display effect, and control the non-target display sub-area in the at least two display sub-areas to be in a second display mode so that the display data output by the non-target display sub-area presents a second display effect.

[0067] The display mode control instruction may be used to indicate that at least one target display sub-area among the multiple display sub-areas obtained by segmentation is in a first display mode, and the first display mode may be a pre-specified display mode, such as a display mode that can achieve a specified color display effect / eye protection function / energy saving, or a display mode designed for a specified application, etc. For example, an e-book mode (E-book mode) specially designed for reading with a black and white display effect, etc.

[0068] Based on this, the present application can predefine the trigger control method of the first display mode. In practical applications, if the detection information meets any trigger control method, a display mode control instruction can be generated, and the processing device can know that it is currently necessary to control at least one display sub-area to enter the first display mode to meet the current user's demand for display data reading. For this, it can be pre-configured under what circumstances, which display sub-area needs to enter the first display mode, such as the display sub-area at a specified position needs to enter the first display mode, etc., and the matching display mode control instruction can be obtained accordingly to select the target display sub-area that matches the display mode control instruction from all display sub-areas, and determine the display sub-area that does not match the display mode control instruction as a non-target display sub-area.

[0069] Afterwards, the display data to be output is obtained and distributed to each corresponding display sub-area. At the same time, for each target display sub-area, its color parameters can be adjusted independently so that its adjusted color parameters are different from the color parameters before the adjustment, so that the display data output in the target display sub-area presents the first display effect; at the same time, for each non-target display sub-area, the current display mode can be retained as the second display mode, or adjusted to a different color residual value to enter the second display mode, etc., so that the display data output by the non-target display sub-area presents the second display effect, and the second display effect is different from the first display effect.

[0070] Exemplarily, if the first display mode is an e-book mode, and the second display mode is a color mode, such as a commonly used color mode determined according to an application scenario, suitable for viewing pictures, video clips, and other scenes that require bright colors, or a movie mode or a game mode, etc., the color parameters corresponding to different color modes are different, and the second display effect achieved by outputting the same display data is different. This application does not limit the size and content of the color parameters corresponding to each display mode, and can be pre-configured and stored as appropriate. In actual applications, after determining the target / non-target display sub-area, read the stored content to determine what color parameters each display sub-area should be adjusted to, and independently adjust the color parameters of each display sub-area accordingly, so that different display sub-areas can present different display effects.

[0071] In this way, Figure 2 As shown (it only shows an example of a scenario in which the global display area is divided into two display sub-areas. It can also be divided into more display sub-areas according to actual needs, and the size, position, etc. of different display sub-areas can be dynamically adjusted. The implementation process is not described in detail in this application). According to the above method, the target display sub-area is determined, and it is required to enter the e-book mode. The display effect of the e-book mode can be achieved by adjusting the color saturation and the gain value of RGB, such as reducing the brightness and reducing the gain value of blue light, such as black and white display, reducing screen reflection and glare, making reading more comfortable, reducing the blue light emitted by the screen, reducing stimulation to the eyes, and realizing eye protection function. For non-target display sub-areas entering the color mode, the best visual effect can be presented, which can better meet the application requirements such as games, watching movies or pictures, and improve the user experience.

[0072] It should be noted that the types of the first display mode and the second display mode of the present application can be pre-configured according to actual scene requirements, including but not limited to the e-book mode and color mode listed above. The embodiment of the present application is only described as an example.

[0073] It can be seen from this that, combined with the above description, refer to Figure 3 The flowchart of a display control method proposed in the first embodiment of the present application is shown in FIG. Figure 3 As shown, the display control method may include:

[0074] Step S31, controlling a display area of ​​a display device to be divided into at least two display sub-areas; the at least two display sub-areas are used to output different display data;

[0075] Step S32, obtaining a display mode control instruction;

[0076] Step S33, determining a target display sub-region matching the display mode control instruction from the at least two display sub-regions;

[0077] Step S34, controlling the target display sub-area to be in a first display mode, so that the display data output by the target display sub-area presents a first display effect, and controlling the non-target display sub-area in at least two display sub-areas to be in a second display mode, so that the display data output by the non-target display sub-area presents a second display effect; wherein the first display effect and the second display effect are different color display effects, which are achieved by adjusting the color parameters of the corresponding display sub-areas.

[0078] In combination with the above description of the structural embodiment of the display device, the present application divides the display area of ​​the display device into at least two display sub-areas. In the process of outputting display data through each display sub-area, independent adjustment of the color parameters of different display sub-areas can be achieved, so that the display data output by the target display sub-area and the non-target display sub-area respectively present different display effects, better meet the display requirements of application scenarios where different display sub-areas output display data, improve the flexibility and diversity of display control, and improve user experience.

[0079] In some embodiments, Figure 4 As shown, the display device may further include: a data collector 140, for collecting facial sensing data of a display data viewer; the facial sensing data indicates the positional relationship of the viewer relative to the display area, thereby determining which display sub-area the current viewer is focusing on, which may be a target display sub-area, so as to control the display sub-area to enter a first display mode according to a pre-configured processing logic, so that rapid adaptive adjustment of the display mode of the target display sub-area can be achieved based on the facial sensing data without manual operation by the user.

[0080] It should be understood that, depending on the different pre-configured processing logics, after determining the target display sub-area that the current viewer is paying attention to according to the method described above, the target display sub-area can be flexibly configured and adjusted according to the actual scene requirements to enter which display mode, including but not limited to the e-book mode, and in scenes such as gaming or watching movies, it can also be a color mode. It can be seen that the contents of the first display mode and the second display mode of the present application can be determined based on the pre-configured information for the display area.

[0081] Based on the above analysis, the above-mentioned processing device 130 may include a first processing unit 131 and a second processing unit 132, wherein the first processing unit 131 can be used to receive the facial sensing data sent by the data collector 140, and obtain the display mode control instruction based on the facial sensing data and then output it; the second processing unit 132 can be used to receive the display mode control instruction, determine the target display sub-area that matches the display mode control instruction among the at least two display sub-areas, control the target display sub-area to be in the first display mode, and the non-target display sub-area among the at least two display sub-areas to be in the second display mode. The implementation process of the embodiment of the present application will not be repeated here.

[0082] It can be seen that this embodiment can use a processor with different processing functions to execute the display control method proposed in this application according to the method described above, and timely and accurately select the target display sub-area and the non-target display sub-area. By independently adjusting the color parameters of each of these two types of display sub-areas, the display data output by each of them presents different color display effects, thereby better meeting the display requirements of different application scenarios, without the need for users to manually switch and adjust, thereby improving the user experience.

[0083] In a possible implementation, the present application can determine which display sub-area the current viewer is focusing on, i.e., the display sub-area viewed in the facial deflection direction, by analyzing the viewer's facial deflection direction, and automatically switch the display mode of the display sub-area to a pre-configured first display mode to change the color display effect presented by the display sub-area. In this regard, the present application can select a suitable artificial intelligence algorithm, such as a facial recognition algorithm, to analyze the facial sensing data and obtain the facial deflection direction. The implementation process is not described in detail in the present application.

[0084] Based on this, Figure 5As shown, the data collector 140 can be an image collector, such as one or more cameras installed on the surface where the display area of ​​the display device is located, and the facial sensing data collected by it is facial image data. In this case, the first processing unit 131 can be an image processor, such as ISP (Image Signal Processing), which is used to analyze the facial image data, obtain the facial deflection direction of the current viewer relative to the display area (the global display area of ​​the display device), and determine the control signal for the first display mode of the display area, which is transmitted to the second processing unit 132, i.e., the display processor, such as the Scaler chip, to switch the target display sub-area in the facial deflection direction to the first display mode (if it is already the first display mode before switching, it remains unchanged here), and at this time, the non-target display sub-area can also be switched to the second display mode. The control process of the display mode of the display sub-area can refer to the description of the corresponding part of the above embodiment, and this embodiment will not be repeated here.

[0085] In order to further reduce the amount of calculation for analyzing the facial deflection direction, reduce power consumption, and improve display control efficiency, as shown in the following example: Figure 6 As shown, the present application can also use a time-of-flight (TOF) sensor to collect facial sensing data. In this case, the first processing unit 131 can use an MCU microprocessor, and the second processing unit 132 is still a display processor, such as a Scaler chip (i.e., a display main control chip), to transmit the facial sensing data to the microprocessor. The microprocessor can use a suitable artificial intelligence AI algorithm to analyze the facial sensing data, and transmit the analysis result as a display mode control instruction to the Scaler chip, so that the Scaler chip can dynamically adjust the display mode of the corresponding target display sub-area in a timely manner, such as adjusting the display sub-area that the user is concerned about to the e-book mode in a timely manner.

[0086] According to the above analysis, refer to Figure 7 The flowchart of the display control method provided in the second embodiment of the present application is shown in FIG. Figure 6 The structure of the display device shown is implemented as Figure 7 As shown, the display control method executed by the microprocessor and the display processor respectively may include but is not limited to the following steps:

[0087] Step S71, the microprocessor obtains facial sensing data of a viewer of the displayed content; the facial sensing data indicates a positional relationship of the viewer relative to a display area of ​​the display device;

[0088] Step S72, the microprocessor inputs the facial sensing data into the face recognition model to perform facial region recognition, and obtains a first number of left face regions and a second number of right face regions sensed by the time-of-flight sensor;

[0089] Step S72, the microprocessor determines the facial deflection direction of the current viewer relative to the display area according to the first number and the second number, as a display mode control instruction for the first display mode of the display area;

[0090] Since the TOF sensor is a method of facial posture estimation that can overcome the limitations of traditional two-dimensional image methods by utilizing depth information, and can achieve high-precision, high-adaptability and real-time performance. A depth map can be generated by measuring the time from the emission to the return of the light signal, thereby providing information about the distance and spatial position of the object. Therefore, in the application of facial deflection direction using the TOF sensor, by classifying and distinguishing the data of the light signal emitted to the face and the data of the light signal reflected from the face, a large amount of data simulation and analysis can be performed on the faces of different groups of people (i.e., different groups with different facial features) in advance in this process, and the corresponding left face area and right face area receive and return data for various groups of people under different facial deflection directions (i.e., different facial deflection angles), thereby indicating which side of the left and right faces deflects more and which side of the face deflects less. Based on this, the analysis and determination of the facial deflection direction of the viewer is achieved.

[0091] Exemplarily, in combination with the above analysis, the present application can divide the entire face into 64 recognition areas, with 32 recognition areas in the left and right areas, namely 32 right face areas and 32 left face areas. On this basis, by analyzing the facial sensing data, the number of recognition areas of the reflected data is determined. If the user's face is deflected to the right, the left face is closer to the display area than the right face, and the 32 left face areas distributed on the left face will basically return data, while the 32 right face areas will be blocked because the right face is partially blocked, resulting in the emission of light signals that cannot reach this part of the right face area, and thus cannot return data, making the number of received right face areas less than 32. In this way, the present application can determine the direction of facial deflection by comparing the first number of left face areas and the second number of right face areas.

[0092] It can be seen that if the first number is greater than the second number, the face is deflected to the right, and the target display sub-area in the direction of facial deflection is the display sub-area on the right side of the display device; conversely, if the first number is less than the second number, the face is deflected to the left, and the target display sub-area in the direction of facial deflection is the display sub-area on the left side of the display device; the first number is equal to the second number, indicating that the face is not deflected at this time, and the original display mode can be maintained, or the display mode of each display sub-area can be switched to the first display mode, or the split screen can be ended, and the display device will output display data in the form of a global display area. At this time, the display data can be an e-book mode to achieve the effect of reducing power consumption, but is not limited to the several implementation methods described in this embodiment.

[0093] Optionally, the present application may also detect facial feature points, locate the facial center, and then calculate the facial deflection direction, such as by analyzing the depth change of the facial feature points and inferring the facial deflection direction. For example, if the depth of the facial feature points on one side is significantly greater than that on the other side, it means that the face is deflected to the side with a shallower depth. In addition, the depth data of the face can be fitted by constructing a three-dimensional geometric model, and the facial deflection direction can be determined by the rotation and translation parameters of the model. The present application does not limit the method for calculating the facial deflection direction.

[0094] According to the above description of the calculation method of the facial deflection direction, in order to ensure the reliability and accuracy of the calculated facial deflection direction, the TOF sensor can be installed at the center or near the center of the front of the display device (i.e., the surface where the display area is located), so that the user can obtain as much and complete facial sensing data as possible at different positions in front of the display device. This application does not limit its installation position.

[0095] Step S73, the microprocessor transmits the display mode control instruction to the display processor;

[0096] Step S74, the display processor selects, from the at least two display sub-areas into which the display area of ​​the display device is divided, a display sub-area located in the facial deflection direction as a target display sub-area, and a display sub-area not located in the facial deflection direction as a non-target display sub-area;

[0097] Step S75, the display processor controls the target display sub-area to be in the first display mode, so that the display data output by the target display sub-area presents a first display effect, and controls the non-target display sub-area of ​​at least two display sub-areas to be in the second display mode, so that the display data output by the non-target display sub-area presents a second display effect.

[0098] In practical applications, the microprocessor and the display processor can communicate via SPI (Serial Peripheral Interface) or GPIO (General Purpose Input Output), but are not limited to these two communication methods. The microprocessor sends the analysis result of the facial deflection direction (which may be facial deflection direction description information or its representation information) to the display processor as a display mode control instruction, so that the display processor learns the first display mode adjustment behavior (such as rotating the facial deflection direction) performed by the viewer, and according to the pre-configured processing logic, automatically adjusts the target display sub-area that the user focuses on in the facial deflection direction to the first display mode, and at this time, the display mode of other non-target display sub-areas can be adjusted to the second display mode or the original display mode can be maintained unchanged.

[0099] Optionally, during the process of adjusting the display modes of different display sub-areas by the facial deflection direction, the display processor can first determine whether the current display mode of the target display sub-area located in the facial deflection direction is the first display mode. If not, the target display sub-area is controlled to switch to the first display mode. If so, no further display mode adjustment is required. Similarly, the display mode adjustment process for non-target display sub-areas is similar, and it can also be determined whether it complies with the pre-configured processing logic. If not, the display mode of the corresponding display sub-area is controlled according to the processing logic. The implementation process is not described in detail in this application.

[0100] It should be understood that, in the case where the display area is divided into a plurality of display sub-areas, after completing the control of the display mode of each display sub-area once by the facial deflection direction according to the method described above, if the user changes the facial deflection direction so that the target display sub-area changes, the processing device 130 of the display device can also readjust the display mode of each display sub-area according to the method described above. Figure 8 The flowchart of the display control method provided in the third embodiment of the present application is shown, and the display control method executed by the processing device may also include:

[0101] Step S81, determining that the facial deflection direction of the viewer relative to the display area switches from a first direction to a second direction, determining the display sub-area located in the second direction as a new target display sub-area, and determining the display sub-area located in the first direction as a new non-target display sub-area;

[0102] Step S82, controlling the second color parameter currently possessed by the new target display sub-area to be updated to the first color parameter, so as to switch from the second display mode to the first display mode;

[0103] Step S83: Control the first color parameter currently possessed by the new non-target display sub-area to be updated to the second color parameter, so as to switch from the first display mode to the second display mode.

[0104] In an embodiment of the present application, the first color parameter is different from the second color parameter, and each may include one or more of color saturation and color gain value. The numerical values ​​of these two color parameters in the present application are not limited and can be determined by the color display effect required to be achieved by the corresponding display mode.

[0105] It can be seen that in actual applications, when the deflection direction of the face changes, the AI ​​adaptive algorithm can be used to adjust the display mode of the new target display sub-area of ​​interest so that it is in the e-book mode, and the non-target display sub-area is switched to the color mode or can be kept in the e-book mode to achieve the effect of reducing power consumption. In other words, step S83 can also be to control the first color parameter currently possessed by the new non-target display sub-area to remain unchanged so as to maintain the first display mode.

[0106] It should be noted that the display processor of the present application can only control the first display mode of the target display sub-area that the user is concerned about by identifying the facial deflection direction when it is determined that the adaptive adjustment function for the first display mode of the display device is in the on state. If the adaptive adjustment function for the first display mode of the display device is in the off state, even after the facial deflection direction is determined according to the method described above, the display processor will not determine the target display sub-area based on it and control its display mode. At this time, according to the display mode configuration information for the at least two display sub-areas divided into the display area, the at least two display sub-areas can be controlled to be in different display modes respectively. The control process is similar to the control process described above and is not described in detail in the present application.

[0107] Of course, if it is determined that the adaptive adjustment function for the first display mode of the display device is in the on state, and before the display mode control instruction is obtained, that is, the display processor has not yet obtained the facial deflection direction, but the display area has been controlled to be divided into at least two display sub-areas, the at least two display sub-areas can still be controlled to be in different display modes according to the display mode configuration information for the at least two display sub-areas divided into the display area. The display area of ​​the display device is divided into a first display sub-area and a second display sub-area.

[0108] In one possible implementation, the above-mentioned display mode configuration information for the display area being divided into at least two display sub-areas can be manually set on a split-screen management interface, such as an OSD (on-screen display) interface. In this case, the display device 120 can also be used to output the split-screen management interface in the display area, and the user can directly operate it. In this process, the processing device 130 can also be used to respond to the split-screen operation of the split-screen management interface, divide the display area into at least two display sub-areas according to the configured split-screen ratio, and determine the display modes of the at least two display sub-areas respectively.

[0109] For example, Figure 2 As shown, during the process of setting the display mode configuration information, after turning on hard split screen in the OSD interface, you can set how many display sub-areas the display area is divided into under hard split screen, and what position distribution relationship is used (how the positions of the display sub-areas are related to each other). Figure 2 The left-right distribution relationship shown in the figure may also be an up-down distribution relationship or other distribution relationship) and the size relationship (such as the relationship between the display sub-areas Figure 2 The 1:1 shown in the figure, and 2:1, 3:4, 16:9, etc. can also be used. The input device can also be used to drag the display sub-area border to customize the size of each display sub-area, etc., and the present application does not impose any restrictions on this), as well as which display sub-area needs to be in the first display mode, which display sub-area needs to process the second display mode, etc., and then, the "Confirm" button can be clicked to obtain the corresponding display mode configuration information, so as to realize the segmentation of the display area and the control of the display mode of each display sub-area after the segmentation in the display control method proposed in the present application.

[0110] by Figure 2 Taking the division of the display area into the first display sub-area and the second display sub-area as an example, the first display sub-area on the left side of the display device can be preset to be in the first display mode (such as the e-book mode), and the second display sub-area on the right side of the display device can be preset to be in the second display mode (such as the color mode). In this way, when the display area is divided into these two display sub-areas, if the facial sensing data is successfully obtained, or it is determined that the adaptive adjustment function is in the off state, the first display sub-area can be controlled to be in the e-book mode, and the second display sub-area can be controlled to be in the color mode. The control processes of these two display modes are independent of each other and do not interfere with each other, thereby improving the diversity of display control.

[0111] It should be understood that if the global display area needs to be divided into more display sub-areas, the position distribution relationship and size relationship (such as proportion) of the multiple display sub-areas can be determined according to actual needs, thereby realizing the division of the global display area. This is equivalent to simulating multiple independent displays inside the display device. This process does not require the display device or the electronic device connected to it to install a driver, has no special requirements for the operating system of the electronic device, is not restricted by the application program, and has strong applicability.

[0112] In addition, regarding the method of turning on the hard split screen mode, it can be realized by a specific physical button or a corresponding function button of the OSD interface, or it can be triggered by the event that the display area enters the first display mode, that is, it is determined that the display area enters the first display mode, and the display area is divided into at least two display sub-areas according to the configured split screen ratio. If the display area is controlled to enter the e-book mode, the display processor will be automatically triggered to turn on the hard split screen, and the display area will be divided, so as to adjust the display mode of each display sub-area according to the methods described above, such as the adjustment method based on the facial deflection direction and the adjustment method based on the display mode configuration information.

[0113] In actual applications, if the hard split screen mode of the display device is not turned on, in order to reduce power consumption, the display processor can control the display area to be in e-book mode. After the hard split screen mode is turned on, the display area is controlled to be divided into at least two display sub-areas. If the adaptive adjustment function is in the off state, the target display sub-area indicated by it can be controlled to be in e-book mode and the non-target display sub-area to be in color mode according to the display mode configuration information. If the adaptive adjustment function is turned on, according to the method described above, based on the facial deflection direction, the corresponding target display sub-area is dynamically controlled to be in e-book mode and the non-target display sub-area is in color mode, etc., but it is not limited to this.

[0114] In some embodiments, for the adjustment of the display modes of different display sub-areas, in addition to the facial deflection direction and display mode configuration information described above, if the communication port 110 obtains multiple display data from different display data sources, and the different display data sources respectively correspond to different display sub-areas into which the display area is divided, so that the display sub-areas output corresponding display data, in this case, the processing device 130 can also select a target display data source from the different display data sources, such as a display data source that meets the current application requirements or belongs to a specified application scenario as the target display data source, and then the display sub-area that outputs the display data from the target display data source can be determined as the target display sub-area that matches the display mode control instruction, and controlled to be in the first display mode.

[0115] In the implementation process of the display device and the display control method thereof described in the above embodiments, the present application can also dynamically adjust the display parameters of the display area, such as by a physical button in the display device or a connected input device, etc., to perform a display parameter adjustment operation on it. In this case, the processing device 130 can also be used to respond to the display parameter adjustment instruction input to the display area, adjust the display parameters of the non-target display sub-area, and do not adjust the display parameters of the target display sub-area. The display parameters include at least one of a color parameter and a performance parameter.

[0116] It can be seen that when different display data are output through different display sub-areas, the user manually adjusts the display parameters of the display device, and the display parameters of all display sub-areas are not adjusted synchronously. Only the display parameters of the non-target display sub-areas in the color mode are adjusted, such as one or more of the resolution, contrast, brightness, color saturation, and color gain, which can be determined according to actual needs. However, the display parameters of the target display sub-area currently in the e-book mode remain unchanged. In this way, in the different color modes listed above, the display parameters of the corresponding non-target display sub-areas need to be adjusted accordingly, and the traditional display parameter adjustment method can still be used to adjust the movie mode to the game mode or other color mode by adjusting the display parameters.

In actual applications, the display device may include more or fewer components than those shown in the accompanying drawings, or combine certain components, such as microphones, speakers, other sensors, power modules, RF components, external ports and other input / output components, etc., which can be determined based on the product form of the display device.
