With the development of display devices towards large size and ultra-high definition, RGB three-dimensional color control liquid crystal display technology has emerged, which can further improve the color gamut. However, in some picture scenes with multiple colors, the display device has some color bleeding problems when displaying such pictures. SUMMARY

[0005] a display panel;

[0006] a backlight assembly; the backlight assembly comprises a plurality of backlight sources;

[0007] a controller coupled to the display panel and the backlight assembly respectively, and configured to:

[0008] generate, based on color distribution information of a single frame of a to-be-displayed picture, continuous at least two frames of backlight signals of the backlight assembly and continuous at least two frames of display panel signals of the display panel; the to-be-displayed picture comprises a first picture region and a second picture region adjacent in position, and a first color corresponding to the first picture region is different from a second color corresponding to the second picture region; the continuous at least two frames of backlight signals comprise a target frame backlight signal and a non-target frame backlight signal; the continuous at least two frames of display panel signals comprise a target frame display panel signal and a non-target frame display panel signal;

[0009] when the target frame arrives, control the backlight assembly according to the target frame backlight signal to make the backlight color of the first picture region and the second picture region be the first color, and control the display panel according to the target frame display panel signal to make the display color of the first picture region and the second picture region be the first color;

[0010] at a time of arrival of a non-target frame, controlling the backlight assembly according to a non-target frame backlight signal to make the backlight color of the first picture area and the second picture area white, and controlling the display panel according to a non-target frame display panel signal to make the display color of the first picture area the first color and the display color of the second picture area a target color; the target color is a color that combines with the first color to form a second color.

[0011] In a second aspect, some embodiments provide a display processing method, the method is applied to a controller of a display device; the display device includes a display panel and a backlight assembly; the backlight assembly includes a plurality of backlight sources; the controller is coupled with the display panel and the backlight assembly respectively;

[0012] The method includes:

[0013] generating, based on color distribution information of a to-be-displayed picture, continuous at least two frames of backlight signals of the backlight assembly and continuous at least two frames of display panel signals of the display panel; the to-be-displayed picture includes a first picture area and a second picture area that are adjacent in position, and a first color corresponding to the first picture area is different from a second color corresponding to the second picture area; the continuous at least two frames of backlight signals include a target frame backlight signal and a non-target frame backlight signal; the continuous at least two frames of display panel signals include a target frame display panel signal and a non-target frame display panel signal;

[0014] at a time of arrival of a target frame, controlling the backlight assembly according to the target frame backlight signal to make the backlight color of the first picture area and the second picture area the first color, and controlling the display panel according to the target frame display panel signal to make the display color of the first picture area and the second picture area the first color;

[0015] at a time of arrival of a non-target frame, controlling the backlight assembly according to the non-target frame backlight signal to make the backlight color of the first picture area and the second picture area white, and controlling the display panel according to a non-target frame display panel signal to make the display color of the first picture area the first color and the display color of the second picture area a target color; the target color is a color that combines with the first color to form a second color.

[0016] The above technical solutions have the following beneficial effects:

[0017] For a frame with at least two colors of to-be-displayed picture, the frame to-be-displayed picture is split into at least two consecutive frames of backlight signals and at least two consecutive frames of display panel signals; wherein, the target frame backlight signal can make the backlight source corresponding to the first picture area and the second picture area both produce the first color, and at the same time, the target frame display panel signal matched with the target frame backlight information can make the first color produced by the backlight source corresponding to the first picture area and the second picture area be transmitted, so as to enhance the color gamut. However, if only the target frame backlight signal and the target frame display panel signal are provided, the first picture area and the second picture area are both the first color, which does not conform to the to-be-displayed picture, because in the to-be-displayed picture, the first picture area is the first color and the second picture area is the second color. In order to make the user perceive that the second picture area is the second color, the present application also displays a target color in the second picture area, and the target color and the first color can form the second color in combination, so that when the screen refresh rate is sufficient, for the user, the second picture area displays the second color (also the superimposed display effect of the target color and the first color). Therefore, the present application increases the non-target frame backlight signal and the corresponding non-target frame display panel signal, the non-target frame backlight signal can make the backlight source corresponding to the first picture area and the second picture area both produce white light, and the corresponding non-target frame display panel signal can make the light of the first color in the white light produced by the backlight source corresponding to the first picture area be transmitted, and the light of the target color in the white light produced by the backlight source corresponding to the second picture area be transmitted, so that for the user, the second picture area visually displays the second color, which not only alleviates the problem of crosstalk, but also ensures that the picture perceived by the user conforms to the to-be-displayed picture.

Figure 3 As shown, the control device 100 may include: a controller 110, a communication interface 130, a user input / output interface, a memory, and a power supply.

[0056] The control device 100 is configured to control the display device 200, and can receive the input operation instructions of the user, and convert the operation instructions into instructions that the display device 200 can recognize and respond to, and play the role of an intermediary between the user and the display device 200 in the interaction.

[0057] In some embodiments, the control device 100 can be a smart device. For example, the control device 100 can install various applications for controlling the display device 200 according to the user's needs.

[0058] In some embodiments, as shown in FIG. 3, the mobile terminal 300 or other smart electronic devices can play a similar function of the control device 100 after installing the application for controlling the display device 200. Figure 1

[0059] The controller 110 includes a processor 112 and a RAM 113 and a ROM 114, a communication interface 130, and a communication bus. The controller 110 is used to control the operation and operation of the control device 100, and the communication and cooperation between the internal components, and the data processing functions of the external and internal.

[0063] The storage 190 is used to store various running programs, data and applications for driving and controlling the control device 100 under the control of the controller. The storage 190 can store various control signal instructions input by the user.

[0064] The power supply 180 is used to provide operating power support for each element of the control device 100 under the control of the controller.

[0065] ​To perform user interactions, in some embodiments, the display device 200 can run an operating system. The operating system is a computer program for managing and controlling hardware resources and software resources in the display device 200. The operating system can provide a user interface to allow a user to interact with the display device 200 and support running various application programs.

[0066] It should be noted that the operating system can be a native operating system based on a specific operating platform, a third-party operating system deeply customized based on a specific operating platform, or an independent operating system specially developed for the display device.

[0067] The operating system can be divided into different modules or levels according to the implemented functions, for example, as shown in FIG. 1, in some embodiments, the system is divided into four layers, from top to bottom, the Applications layer (referred to as the “application layer”), the Application Framework layer (referred to as the “framework layer”), the system library layer, and the kernel layer. Figure 4

[0068] In some embodiments, the application layer is used to provide services and interfaces for application programs, so that the display device 200 can run application programs and interact with users based on the application programs. At least one application program can run in the application layer, which can be a window (Window) program, a system setting program, or a clock program provided by the operating system, or an application program developed by a third-party developer. In specific implementation, the application programs in the application layer are not limited to the above examples.

[0069] The framework layer provides application programming interfaces (APIs) and programming frameworks for application programs. The application framework layer includes some pre-defined functions. The application framework layer is equivalent to a processing center that decides which application program in the application layer to act. The application program can access the resources in the system and obtain the services of the system through the API interface during execution.

[0070] As shown in FIG. 1, in some embodiments, the system library layer includes a system library, which is a collection of pre-written code that provides common functionality for use by applications. The system library layer is equivalent to a library that provides a set of functions that can be called from an application program. The system library layer provides a set of functions that can be called from an application program. Figure 4 ​As shown, in the embodiment of the present application, the application framework layer includes a view system, managers, content providers, etc., wherein the view system can design and implement the interface and interaction of the application, and the view system includes lists, grids, text boxes, buttons, etc. The manager includes at least one of the following modules: an activity manager for interacting with all activities running in the system; a location manager for providing system services or applications with access to the system location service; a package manager for retrieving various information related to the application packages currently installed on the device; a notification manager for controlling the display and clearing of notification messages; and a window manager for managing icons, windows, toolbars, wallpapers, and desktop widgets on the user interface.

[0071] In some embodiments, the activity manager is used to manage the lifecycle of each application and common navigation back functions, such as controlling application exit, opening, and back. The window manager is used to manage all window programs, such as obtaining the display screen size, determining whether there is a status bar, locking the screen, taking screenshots, and controlling changes in display windows, such as shrinking, shaking, or distorting the display window.

[0072] In some embodiments, the system runtime layer can provide support for the framework layer. When the framework layer is used, the operating system will run the instruction library contained in the system runtime layer, such as the C / C++ instruction library, to implement the functions to be implemented by the framework layer.

[0073] In some embodiments, the kernel layer is a functional layer between the hardware and software of the display device 200. The kernel layer can implement functions such as hardware abstraction, multitasking, and memory management. Figure 4 As shown, the kernel layer can be configured with hardware drivers, and the drivers included in the kernel layer can be at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

[0074] It should be noted that the above examples are only a simple division of the operating system function, and do not constitute a limitation on the specific operating system form of the display device 200 in the embodiments of the present application. According to the function of the display device, the type of the operating system, and other factors, the number and specific type of the levels contained in the operating system can be in other forms.

[0075] The display device includes a backlight assembly and a display panel. The backlight assembly includes a plurality of backlight sources, which can emit light when working. The backlight sources include R-type backlight sources, G-type backlight sources, and B-type backlight sources. In some scenarios, one R-type backlight source, one G-type backlight source, and one B-type backlight source can be regarded as a group of backlight sources, and a group of backlight sources corresponds to one pixel position. When the R-type backlight source, the G-type backlight source, and the B-type backlight source of a certain group emit light in equal amounts, the group of backlight sources is regarded as generating white light (which can be referred to as white light for short).

[0076] The display panel can include an OC assembly, and the English full name of OC is open cell, which can be translated into Chinese as open cell. The display panel mainly selectively transmits or blocks the light emitted by the backlight assembly. For example, after each group of backlight sources of the backlight assembly emits white light, the selective transmission or blocking of the display panel can make the red light in the white light transmit and the green light and the blue light in the white light be blocked. For another example, after each group of backlight sources of the backlight assembly emits white light, the selective transmission or blocking of the display panel can adjust the transmission amounts of the red light, the green light, and the blue light in the white light. The backlight assembly provides light, and the display panel controls the transmission amount and the color of the light, so that a corresponding picture can be presented on the screen.

[0077] When the display device displays some pictures including multiple colors, color bleeding may occur. The color bleeding problem is introduced by taking a white frame picture with a red background as an example.

[0078] For example, the picture to be displayed is Figure 5 The red frame picture shown in the figure has a red color in the picture area 501 and a white color in the picture area 502. However, the actually displayed picture is as shown in Figure 6 The white color exceeds its corresponding picture area, and color bleeding occurs. For the color bleeding problem shown in Figure 6 The color bleeding problem can be alleviated by adjusting the backlight assembly to turn on all three types of backlight sources to generate white light. However, this method can greatly reduce the color gamut of the display device, and loses the significance and value of the RGB three-dimensional color control liquid crystal display technology. Specifically, if a picture with a white frame and a red background is to be displayed, Figure 5In the picture shown, in the backlight assembly, each group of backlight sources corresponding to picture areas 501 and 502 generates white light (that is, the three types of backlight sources R, G, and B in each group of backlight sources emit equal amounts of light). The display panel allows the red light in the white light generated by the backlight source corresponding to picture area 501 to pass through, while the green and blue light are blocked. The display panel also allows the white light generated by the backlight source corresponding to picture area 501 to pass through. As a result, a red background and white frame picture can be presented on the screen, alleviating the cross-color phenomenon. However, this method significantly reduces the color gamut because the backlight sources corresponding to picture area 501 all generate white light.

[0079] For another example, the picture to be displayed is Figure 7 In the green background and white frame picture shown, the color of the picture area 701 is green and the color of the picture area 702 is white; however, the actual displayed picture is as follows Figure 8 As shown in the figure, white exceeds its corresponding screen area and color bleeding occurs. Figure 8 The color cross-talk problem shown can be solved by adjusting the backlight components and turning on all three types of backlight sources to produce white light. However, although this method can alleviate the color cross-talk problem, the color gamut of the display device is greatly reduced, and the significance and value of RGB three-dimensional color control liquid crystal display technology is lost. Specifically, if you want to display Figure 7 In the picture shown, in the backlight assembly, each backlight group corresponding to the picture areas 701 and 702 generates white light (that is, the three types of backlight sources R, G, and B in each backlight group emit equal amounts of light). The display panel allows the green light in the white light generated by the backlight source corresponding to the picture area 701 to pass through, while the red and blue light are blocked. The display panel also allows the white light generated by the backlight source corresponding to the picture area 701 to pass through. As a result, a green background with a white frame can be presented on the screen, alleviating the cross-color phenomenon. However, this method significantly reduces the color gamut because the backlight sources corresponding to the picture area 501 all generate white light.

[0080] For another example, the picture to be displayed is Figure 9 In the blue background and white frame picture shown, the color of the picture area 901 is blue and the color of the picture area 902 is white; however, the actual displayed picture is as follows Figure 10 As shown in the figure, white exceeds its corresponding screen area and color bleeding occurs. Figure 10 The color cross-talk problem shown can be solved by adjusting the backlight components and turning on all three types of backlight sources to produce white light. However, although this method can alleviate the color cross-talk problem, the color gamut of the display device is greatly reduced, and the significance and value of RGB three-dimensional color control liquid crystal display technology is lost. Specifically, if you want to display Figure 9As shown in the picture, in the backlight assembly, each group of backlight sources corresponding to the picture areas 901 and 902 generates white light (that is, each group of backlight sources emits light in equal amounts of R, G, and B backlight sources), the display panel allows the blue light in the white light generated by the backlight sources corresponding to the picture area 901 to pass through, and the red light and the green light are blocked. The display panel also allows the white light generated by the backlight sources corresponding to the picture area 701 to pass through. Thus, a blue and white frame picture can be presented on the screen, and the color bleeding phenomenon is alleviated. However, this way causes a significant reduction in the color gamut because the backlight sources corresponding to the picture area 501 all generate white light.

[0081] In addition, under the terminal picture of solid color and white text, the user experience is also greatly reduced, and the RGB three-dimensional color control liquid crystal display technology is not fully utilized. For the above problems, even if the algorithm optimization is increased, it is difficult to achieve smooth transition at the junction, which will cause the entire display picture to be layered, the color performance to be excessively uneven, and the color performance to be relatively inconsistent, as shown in Figure 11 、 Figure 12 and Figure 13 .

[0082] Therefore, the present application provides a display device. The display device includes a display panel, a backlight assembly, and a controller. The backlight assembly includes a plurality of backlight sources; the controller is coupled to the display panel and the backlight assembly, respectively. The controller is configured to perform steps S1401-S1403 shown in FIG. 14(a).

[0083] Step S1401, based on the color distribution information of the single frame of the to-be-displayed picture, generating at least two consecutive frames of backlight signals of the backlight assembly and at least two consecutive frames of display panel signals of the display panel.

[0084] The to-be-displayed picture includes a first picture area and a second picture area adjacent in position, and a first color corresponding to the first picture area is different from a second color corresponding to the second picture area; the at least two consecutive frames of backlight signals include a target frame of backlight signals and a non-target frame of backlight signals; and the at least two consecutive frames of display panel signals include a target frame of display panel signals and a non-target frame of display panel signals.

[0085] The controller can analyze the to-be-displayed picture after obtaining the to-be-displayed picture of a single frame, to obtain color distribution information, and determine picture areas of various colors according to the color distribution information. In the to-be-displayed picture, a picture area of a certain color is supposed to display the color, but when actually displayed in a traditional manner, a part of the picture area close to a picture area of another color displays the other color, that is, the other color exceeds its corresponding picture area. The certain color can be referred to as a first color, and the other color can be referred to as a second color. The picture area of the first color is referred to as a first picture area, and the picture area of the second color is referred to as a second picture area. The first picture area and the second picture area are adjacent in position and have a connection relationship, and at the connection position of the two, a side close to the first picture area is supposed to display the first color, but when displayed in a traditional manner, the second color is displayed, and color bleeding occurs.

[0086] After the first color, the second color, the first picture area, and the second picture area are determined, the application generates at least two consecutive frames of backlight signals and at least two consecutive frames of display panel signals. The at least two consecutive frames of backlight signals include a target frame of backlight signals, and the at least two consecutive frames of display panel signals include a target frame of display panel signals. The target frame of backlight signals and the target frame of display panel signals correspond to the same time point.

[0087] The target frame of backlight signals provided by the application can make the backlight sources corresponding to the first picture area and the second picture area generate the first color. Meanwhile, the application increases a target frame of display panel signal matched with the target frame of backlight information. The target frame of display panel signal can make the first color generated by the backlight sources corresponding to the first picture area and the second picture area be transmitted, thereby enhancing the color gamut.

[0088] After receiving the input to-be-displayed picture, the controller can extract the to-be-displayed picture. Through SOC signal processing, at least two consecutive frames of backlight signals are obtained. Through SOC signal processing and in combination with Tcon signal input, at least two consecutive frames of display panel signals can be obtained, as shown in FIG. 14(b). The full name of SOC in English is System on Chip, which can be translated into Chinese as System on Chip. The full name of Tcon in English is Timing Controller, which can be translated into Chinese as Timing Controller.

[0089] Step S1402, when the time point of the target frame arrives, the backlight assembly is controlled according to the target frame of backlight signals, and the display panel is controlled according to the target frame of display panel signals.

[0090] After obtaining the at least two consecutive frames of backlight signals and the at least two consecutive frames of display panel signals, each frame has a corresponding time point. Referring to FIG. 14(c), when the controller monitors that the time point of the target frame arrives, the backlight assembly can be controlled according to the target frame of backlight signals, and the display panel can be controlled according to the target frame of display panel signals.

[0091] The controller controls the backlight assembly according to the target frame backlight signal, so that the backlight color of the first picture area and the second picture area is the first color, that is, the backlight source corresponding to the first picture area and the second picture area generates the first color.

[0092] The controller controls the display panel according to the target frame display panel signal, so that the display color of the first picture area and the second picture area is the first color, that is, the first color generated by the backlight source corresponding to the first picture area and the second picture area is transmitted.

[0093] By generating the first color by the backlight source corresponding to the first picture area and the second picture area, and transmitting the first color generated by the backlight source corresponding to the first picture area and the second picture area, the color gamut can be increased.

[0094] At step S1403, when the time of the non-target frame arrives, the backlight assembly is controlled according to the non-target frame backlight signal, and the display panel is controlled according to the non-target frame display panel signal.

[0095] However, if only the target frame backlight signal and the target frame display panel signal are provided, the first picture area and the second picture area are both the first color, which does not match the to-be-displayed picture, because in the to-be-displayed picture, the first picture area is the first color, and the second picture area is the second color.

[0096] In order to make the user perceive that the second picture area is the second color, the present application also displays a target color in the second picture area, and the target color and the first color can form the second color in combination, so that when the screen refresh rate is sufficient, the user perceives that the second picture area displays the second color (also the superimposed display effect of the target color and the first color). Therefore, the present application increases the non-target frame backlight signal and the corresponding non-target frame display panel signal. The non-target frame backlight signal can make the backlight color corresponding to the first picture area and the second picture area be white, and the corresponding non-target frame display panel signal can make the light of the first color in the white light generated by the backlight source corresponding to the first picture area be transmitted, and the light of the target color in the white light generated by the backlight source corresponding to the second picture area be transmitted. In this way, the user visually perceives that the second picture area displays the second color, which not only alleviates the problem of color crosstalk, but also ensures that the picture perceived by the user matches the to-be-displayed picture.

[0097] It can be understood that the target color and the first color can form the second color in combination, that is, the target color is a color that forms the second color in combination with the first color.

[0098] Referring to Fig. 14(c), when the time of the non-target frame arrives, the controller controls the backlight assembly according to the non-target frame backlight signal and controls the display panel according to the non-target frame display panel signal.

[0099] Specifically, the controller controls the backlight assembly according to the non-target frame backlight signal so that the backlight color of the first picture area and the second picture area is white, i.e., the backlight source corresponding to the first picture area and the second picture area can generate white light.

[0100] The controller controls the display panel according to the non-target frame display panel signal so that the display color of the first picture area is the first color and the display color of the second picture area is the target color, i.e., the light of the first color in the white light generated by the backlight source corresponding to the first picture area is transmitted and the light of the target color in the white light generated by the backlight source corresponding to the second picture area is transmitted, so that the second picture area visually displays the second color for the user, which not only alleviates the problem of color bleeding but also ensures that the picture perceived by the user conforms to the picture to be displayed.

[0101] The picture to be displayed is Figure 5 Taking the red-bottom white-frame picture shown as an example, when the picture is displayed according to the conventional technology, the color bleeding is mainly because the white color exceeds the corresponding picture area, which is specifically shown as follows: for the junction of the picture area 502 and the picture area 501, white color appears on the side of the picture area 501 in the junction.

[0102] The present application adds the target frame backlight signal, which can make the backlight source corresponding to the picture area 501 and the picture area 502 generate red light and can not generate green light and blue light, and adds the target frame display panel signal matched with the target frame backlight signal, which can make the red light generated by the backlight source corresponding to the picture area 501 and the picture area 502 be transmitted, thereby enhancing the color gamut and making the advantage of the RGB three-dimensional color control technology can be effectively exerted. However, if only the target frame backlight signal and the target frame display panel signal are provided, the picture area 501 and 502 are both red, which does not conform to the red-bottom white-frame picture. Figure 5 Figure 5 ​The red frame with white border is shown. The picture area 501 is red, and the picture area 502 is white. In order to make the user perceive that the picture area 502 is white, the green and blue (or the mixture of green and blue) also need to be displayed in the picture area 502. Thus, when the screen refresh rate is sufficient, the picture area 502 displays white (i.e., the superposition effect of red, green and blue) to the user. Therefore, the application increases the non-target frame backlight signal and the corresponding non-target frame display panel signal. The non-target frame backlight signal can make the backlight source corresponding to the picture area 501 and the picture area 502 generate white light. The corresponding non-target frame display panel signal can make the red light in the white light generated by the backlight source corresponding to the picture area 501 be transmitted, and the green and blue light in the white light generated by the backlight source corresponding to the picture area 502 be transmitted. Thus, the picture area 502 displays white in the vision of the user, which not only alleviates the problem of color bleeding, but also ensures that the picture perceived by the user is consistent with Figure 5 The picture shown is consistent.

[0103] The picture to be displayed is Figure 7 Taking the red frame with white border as an example, when the picture is displayed according to the traditional technology, the color bleeding is mainly because the white color exceeds the corresponding picture area. Specifically, for the junction of the picture area 702 and the picture area 701, the white color appears on the side of the picture area 701 in the junction.

[0104] The application increases the target frame backlight signal, which can make the backlight source corresponding to the picture area 701 and the picture area 702 generate green light, and can not generate red light and blue light. At the same time, the target frame display panel signal matched with the target frame backlight information is increased. The target frame display panel signal can make the green light generated by the backlight source corresponding to the picture area 701 and the picture area 702 be transmitted, thereby enhancing the color gamut, so that the advantages of the RGB three-dimensional color control technology can be effectively exerted. However, if only the target frame backlight signal and the target frame display panel signal are used, the picture area 701 and 702 are both green, which is inconsistent with Figure 7 the green frame with white border, because in the picture area 702 Figure 7In the illustrated green bottom white frame picture, picture area 701 is green, and picture area 702 is white; in order to make the user perceive that picture area 702 is white, red and blue (or a mixture of red and blue) also need to be displayed in picture area 702; thus, when the screen refresh rate is sufficient, picture area 702 displays white (i.e., the superposition effect of red, green and blue) to the user; therefore, the present application increases the non-target frame backlight signal and the corresponding non-target frame display panel signal; the non-target frame backlight signal can make the backlight source corresponding to picture area 701 and picture area 702 generate white light; the corresponding non-target frame display panel signal can make the green light in the white light generated by the backlight source corresponding to picture area 701 be transmitted, and the red light and blue light in the white light generated by the backlight source corresponding to picture area 702 be transmitted; thus, picture area 702 displays white in the vision of the user, which not only alleviates the problem of crosstalk, but also ensures that the picture perceived by the user is consistent with the picture displayed on the screen. Figure 7 The illustrated picture is consistent.

[0105] In the above embodiment, for a frame of display picture with at least two colors, the frame of display picture is split into at least two consecutive frames of backlight signals and at least two consecutive frames of display panel signals; wherein the target frame of backlight signal can make the backlight source corresponding to the first picture area and the second picture area generate the first color, and the target frame of display panel signal matched with the target frame of backlight information can make the first color generated by the backlight source corresponding to the first picture area and the second picture area be transmitted, thereby enhancing the color gamut, so that the advantages of RGB three-dimensional color control technology can be effectively exerted. However, if only the target frame of backlight signal and the target frame of display panel signal are provided, the first picture area and the second picture area are both the first color, which does not conform to the display picture, because in the display picture, the first picture area is the first color and the second picture area is the second color. In order to make the user perceive that the second picture area is the second color, the present application further displays a target color in the second picture area, and the target color and the first color can form the second color in combination, so that when the screen refresh rate is sufficient, the second picture area displays the second color (also the superimposed display effect of the target color and the first color) for the user. Therefore, the present application increases the non-target frame of backlight signal and the corresponding non-target frame of display panel signal, the non-target frame of backlight signal can make the backlight color corresponding to the first picture area and the second picture area be white, and the corresponding non-target frame of display panel signal can make the light of the first color in the white light generated by the backlight source corresponding to the first picture area be transmitted, and the light of the target color in the white light generated by the backlight source corresponding to the second picture area be transmitted, so that the second picture area visually displays the second color for the user, which not only relieves the problem of color bleeding, but also ensures that the picture perceived by the user conforms to the display picture. Through the adjustment of the signal matching of the backlight assembly and the display panel, the user's visual experience can be improved without changing the cost, and the application of RGB three-dimensional color control technology can be further improved.

[0106] In one embodiment, the controller is further configured to: when the number of non-target frames is two, obtain a first sub-target color and a second sub-target color according to the color required to combine the first color to form the second color; wherein the first sub-target color and the second sub-target color belong to the target color.

[0107] According to the non-target frame display panel signal, the display panel is controlled to make the display color of the first picture area be the first color and the display color of the second picture area be the target color, including: when the time of one of the non-target frames arrives, according to the non-target frame display panel signal, the display panel is controlled to make the display color of the first picture area be the first color and the second picture area be a first sub-target color; when the time of another non-target frame arrives, according to the non-target frame display panel signal, the display panel is controlled to make the display color of the first picture area be the first color and the second picture area be a second sub-target color.

[0108] In the example shown in the figure, the first color is red and the second color is white. Figure 5 In the example shown in the figure, the first color is red and the second color is white.

[0109] The target frame backlight signal can make the backlight sources corresponding to the picture area 501 and the picture area 502 all produce red light, and can not produce green light and blue light; the target frame display panel signal matched with the target frame backlight information can make the red light produced by the backlight sources corresponding to the picture area 501 and the picture area 502 be transmitted, thereby enhancing the color gamut.

[0110] Red, green and blue can form white, so the colors required to form white in combination with red include green and blue; the controller can take green as the first sub-target color and take blue as the second sub-target color. Green and blue belong to the target color.

[0111] When the number of non-target frames is two, the controller can generate two non-target frame backlight signals, which can make the backlight sources corresponding to the picture area 501 and the picture area 502 all produce white light.

[0112] The controller can also generate two non-target frame display panel signals according to the first sub-target color and the second sub-target color. One of the non-target frame display panel signals can make the red light in the white light produced by the backlight source corresponding to the picture area 501 be transmitted and the green light produced by the backlight source corresponding to the picture area 502 be transmitted; the other non-target frame display panel signal can make the red light in the white light produced by the backlight source corresponding to the picture area 501 be transmitted and the blue light produced by the backlight source corresponding to the picture area 502 be transmitted.

[0113] The controller can control the backlight assembly and the display panel after obtaining the continuous three frame backlight signals and the continuous three frame display panel signals. The continuous three frame backlight signals include the target frame backlight signal and the two non-target frame backlight signals, and the continuous three frame display panel signals include the target frame display panel signal and the two non-target frame display panel signals.

[0114] The target frame backlight signal and the target frame display panel signal both belong to the target frame, and the target frame backlight signal and the target frame display panel signal are regarded as a group of signals (hereinafter referred to as group A signals). Since the two non-target frame backlight signals are the same, one non-target frame backlight signal can be randomly selected to be matched with one non-target frame display panel signal to form a group of signals (hereinafter referred to as group B signals); the other non-target frame backlight signal is matched with the other non-target frame display panel signal to form another group of signals (hereinafter referred to as group C signals). After determining the three groups of signals, the display order of the three groups of signals can be determined, and the sorting manner can be random; in the display order from first to last, for example, it is {group A signals, group B signals, group C signals}, for example, it is {group B signals, group A signals, group C signals}, for example, it is {group B signals, group C signals, group A signals}, for example, it is {group C signals, group B signals, group A signals}.

[0115] The control process is introduced taking the display order of {group A signals, group B signals, group C signals} as an example:

[0116] The controller controls the backlight assembly according to the target frame backlight signal in the group A signals, and controls the display panel according to the target frame display panel signal in the group A signals; in this way, the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly all produce red light, and the red light produced by the backlight sources corresponding to the picture area 501 and the picture area 502 is transmitted.

[0117] Then, the controller controls the backlight assembly according to the non-target frame backlight signal in the group B signals, and controls the display panel according to the non-target frame display panel signal in the group B signals; in this way, the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly all produce white light, and the red light in the white light produced by the backlight sources corresponding to the picture area 501 is transmitted, and if the non-target frame display panel signal in the group B signals is generated according to green, the green light produced by the backlight sources corresponding to the picture area 502 is transmitted.

[0118] Then, the controller controls the backlight assembly according to the non-target frame backlight signal in the group C signals, and controls the display panel according to the non-target frame display panel signal in the group C signals; in this way, the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly all produce white light, and the red light in the white light produced by the backlight sources corresponding to the picture area 501 is transmitted, and if the non-target frame display panel signal in the group B signals is generated according to blue, the blue light produced by the backlight sources corresponding to the picture area 502 is transmitted.

[0119] Thus, for the user, the picture area 501 is visually displayed in red, and the picture area is visually displayed in white, which ensures that the picture perceived by the user is consistent with the picture displayed on the display panel. Figure 5While the displayed image is consistent with the original, it can also alleviate the problem of cross-color and enhance the color gamut.

[0120] In one embodiment, the controller is further configured to: when the number of non-target frames is one frame, obtain multiple color component values ​​of the second color and multiple color component values ​​of the first color; subtract each color component value of the second color from the corresponding color component value of the first color to obtain multiple color component difference values ​​to determine the target color.

[0121] by Figure 5 Taking the red background and white frame image as an example, in this example, the first color is red and the second color is white. The target frame backlight signal can cause the backlight sources corresponding to image area 501 and image area 502 to both generate red light, while omitting green and blue light. The target frame display panel signal matching the target frame backlight information can transmit the red light generated by the backlight sources corresponding to image area 501 and image area 502, thereby enhancing the color gamut.

[0122] Red, green, and blue combine to form white, so the colors required to combine with red to form white include green and blue; the controller can use green as the first sub-target color and blue as the second sub-target color.

[0123] When the number of non-target frames is one, the controller can obtain the three color component values ​​of white (255, 255, 255) and the three color component values ​​of red (255, 0, 0); subtract the R color component value of white from the R color component value of red, subtract the G color component value of white from the G color component value of red, and subtract the B color component value of white from the B color component value of red, and the three color component values ​​obtained are (0, 255, 255), which represent the target color. The controller can generate a non-target frame display panel signal based on the target color. The non-target frame display panel signal can allow the red light in the white light generated by the backlight source corresponding to the screen area 501 to be transmitted, and the green light and blue light in the white light generated by the backlight source corresponding to the screen area 502 to be transmitted.

[0124] After receiving two consecutive frames of backlight signals and two consecutive frames of display panel signals, the controller can control the backlight assembly and the display panel. The two consecutive frames of backlight signals include the target frame backlight signal and the non-target frame backlight signal, and the two consecutive frames of display panel signals include the target frame display panel signal and the non-target frame display panel signal.

[0125] The target frame backlight signal and the target frame display panel signal both belong to the target frame, and the target frame backlight signal and the target frame display panel signal are regarded as a group of signals (hereinafter referred to as group A signals). The non-target frame backlight signal and the non-target frame display panel signal both belong to the non-target frame, and the non-target frame backlight signal and the non-target frame display panel signal are regarded as a group of signals (hereinafter referred to as group B signals).

[0126] After determining the two groups of signals, the display order of the two groups of signals can be determined, and the sorting manner can be random; in the display order from first to last, for example, it is {group A signals, group B signals}, for example, it is {group B signals, group A signals}. Taking the display order of {group A signals, group B signals} as an example, the control process is introduced as follows:

[0127] Table 1

[0128] Group A gray scale Group B gray scale Backlight signal Red light White light Display panel signal - picture area 502 (255，0，0) (0，255，255) Display panel signal - picture area 501 (255，0，0) (255，0，0)

[0129] Referring to Table 1, the gray scale of the target frame backlight signal in group A signals in the picture area 501 and 502 can be set to the gray scale value corresponding to red light, such as (255, 0, 0); the gray scale of the target frame display panel signal in group A signals in the picture area 502 can be set to (255, 0, 0), and the gray scale in the picture area 501 is set to (255, 0, 0). Thus, the target frame backlight signal in group A signals can make the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly produce red light, and the target frame display panel signal in group A signals can make the red light produced by the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly be transmitted, as shown in FIG. 1. Figure 15

[0130] The gray scale of the non-target frame backlight signal in group B signals in the picture area 501 and 502 can be set to the gray scale value corresponding to white light, such as (255, 255, 255); the gray scale of the non-target frame display panel signal in group B signals in the picture area 502 can be set to (0, 255, 255), and the gray scale in the picture area 501 is set to (255, 0, 0). Thus, the non-target frame backlight signal in group B signals can make the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly produce white light, and the non-target frame display panel signal in group B signals can make the green light and blue light in the white light produced by the backlight sources corresponding to the picture area 502 in the backlight assembly be transmitted, as shown in FIG. 2. Figure 15

[0131] ​​The controller controls the backlight assembly according to the target frame backlight signal in the A group signal, and controls the display panel according to the target frame display panel signal in the A group signal; thus, the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly all generate red light, and the red light generated by the backlight sources corresponding to the picture area 501 and the picture area 502 is transmitted.

[0132] Then, the controller controls the backlight assembly according to the non-target frame backlight signal in the B group signal, and controls the display panel according to the non-target frame display panel signal in the B group signal; thus, the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly all generate white light, and the red light in the white light generated by the backlight sources corresponding to the picture area 501 is transmitted, and the green light and the blue light in the white light generated by the backlight sources corresponding to the picture area 502 are transmitted.

[0133] Thus, for the user, the picture area 501 visually displays red color, and the picture area 502 visually displays white color, which guarantees the picture perceived by the user to be consistent with the picture shown, and at the same time, can relieve the color bleeding problem and enhance the color gamut. Figure 5

[0134] The green color and the white color are combined to form a white color, and thus the controller can take the green color as the first target color and take the white color as the second target color. Figure 7 The green color and the white color are combined to form a white color, and thus the controller can take the green color as the first target color and take the white color as the second target color.

[0135] The target frame backlight signal can make the backlight sources corresponding to the picture area 701 and the picture area 702 all generate green light, and can not generate red light and blue light; the target frame display panel signal matched with the target frame backlight information can make the green light generated by the backlight sources corresponding to the picture area 701 and the picture area 702 be transmitted, thereby enhancing the color gamut.

[0136] The red color, the green color and the blue color are combined to form a white color, and thus the colors required to form the white color with the green color include the red color and the blue color; the controller can take the red color as the first sub-target color and take the blue color as the second sub-target color.

[0137] ​When the number of non-target frames is one frame, the controller can obtain three color component values of white (255, 255, 255) and three color component values of green (0, 255, 0); subtract the R color component value of white from the R color component value of green, subtract the G color component value of white from the G color component value of green, and subtract the B color component value of white from the B color component value of green, to obtain three color component values (255, 0, 255), which represent the target color. The controller can generate a non-target frame display panel signal according to the target color. The non-target frame display panel signal can cause the green light in the white light generated by the backlight source corresponding to the picture area 701 to be transmitted, and the red light and blue light in the white light generated by the backlight source corresponding to the picture area 702 to be transmitted.

[0138] The controller can control the backlight assembly and the display panel after obtaining two consecutive frames of backlight signals and two consecutive frames of display panel signals. The two consecutive frames of backlight signals include a target frame backlight signal and a non-target frame backlight signal, and the two consecutive frames of display panel signals include a target frame display panel signal and a non-target frame display panel signal.

[0139] The target frame backlight signal and the target frame display panel signal both belong to the target frame, and the target frame backlight signal and the target frame display panel signal are regarded as a group of signals (hereinafter referred to as D group of signals). The non-target frame backlight signal and the non-target frame display panel signal both belong to the non-target frame, and the non-target frame backlight signal and the non-target frame display panel signal are regarded as a group of signals (hereinafter referred to as E group of signals).

[0140] After determining the two groups of signals, the display order of the two groups of signals can be determined, and the sorting method can be random; in the display order from first to last, for example, it is {D group of signals, E group of signals}, for example, it is {E group of signals, D group of signals}. Taking the display order of {D group of signals, E group of signals} as an example to introduce the control process:

[0141] Table 2

[0142] Group D gray scale Group E gray scale Backlight signal Green light White light Display panel signal - picture area 702 (0，255，0) (255，0，255) Display panel signal - picture area 701 (0，255，0) (0，255，0)

[0143] Referring to Table 2, the target frame backlight signal in the D group of signals can set the gray scale of the picture area 701 and 702 to the corresponding gray scale value of green light, such as (0, 255, 0); the target frame display panel signal in the D group of signals can set the gray scale of the picture area 702 to (0, 255, 0), and the gray scale of the picture area 501 to (0, 255, 0). Therefore, the target frame backlight signal in the D group of signals can cause the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly to generate green light, and the target frame display panel signal in the D group of signals can cause the green light generated by the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly to be transmitted,Figure 16 shown.

[0144] The non-target frame backlight signal in the E group of signals can be set to a grayscale value corresponding to white light in the picture areas 701 and 702, such as (255, 255, 255); the non-target frame display panel signal in the E group of signals can be set to a grayscale value corresponding to white light in the picture area 702, and to a grayscale value corresponding to the picture area 501, such as (0, 255, 0). As a result, the non-target frame backlight signal in the E group of signals can make the backlight sources corresponding to the picture areas 701 and 702 in the backlight assembly generate white light, and the non-target frame display panel signal in the E group of signals can make the red light and blue light in the white light generated by the backlight source corresponding to the picture area 502 in the backlight assembly be transmitted, such as Figure 16 shown.

[0145] The controller controls the backlight assembly according to the target frame backlight signal in the D group signal, and controls the display panel according to the target frame display panel signal in the D group signal; in this way, the backlight sources corresponding to the picture area 701 and the picture area 702 in the backlight assembly both generate green light, and the green light generated by the backlight sources corresponding to the picture area 701 and the picture area 702 is transmitted.

[0146] Next, the controller controls the backlight assembly according to the non-target frame backlight signal in the E group signal, and controls the display panel according to the non-target frame display panel signal in the E group signal; in this way, the backlight sources corresponding to the picture area 701 and the picture area 702 in the backlight assembly both generate white light, the green light in the white light generated by the backlight source corresponding to the picture area 701 is transmitted, and the red light and blue light in the white light generated by the backlight source corresponding to the picture area 702 are transmitted.

[0147] Therefore, for the user, the screen area 701 is visually displayed in green, and the screen area 502 is visually displayed in white, ensuring that the screen perceived by the user is consistent with the Figure 7 While the displayed image is consistent with the original, it can also alleviate the problem of cross-color and enhance the color gamut.

[0148] by Figure 9 Take the blue background and white frame picture as an example. In this example, the first color is blue and the second color is white.

[0149] The target frame backlight signal can make the backlight sources of the corresponding picture area 901 and the picture area 902 produce blue light, and not produce red light and green light; the target frame display panel signal that matches the target frame backlight information can make the blue light generated by the backlight sources of the corresponding picture area 901 and the picture area 902 pass through, thereby enhancing the color gamut.

[0150] The red, green and blue colors can be combined to form white color, and thus the colors required to form white color in combination with blue color include red and green color; the controller can take the red color as the first sub-target color and the green color as the second sub-target color.

[0151] When the number of non-target frames is one frame, the controller can obtain three color component values of white color (255, 255, 255) and three color component values of blue color (0, 0, 255); subtract the R color component value of blue color from the R color component value of white color, subtract the G color component value of blue color from the G color component value of white color, and subtract the B color component value of blue color from the B color component value of white color, to obtain three color component values (255, 255, 0), which represent the target color. The controller can generate a non-target frame display panel signal according to the target color. The non-target frame display panel signal can cause the blue light in the white light generated by the backlight source corresponding to the picture area 901 to be transmitted, and the red light and green light in the white light generated by the backlight source corresponding to the picture area 902 to be transmitted.

[0152] The controller can control the backlight assembly and the display panel after obtaining two consecutive frame backlight signals and two consecutive frame display panel signals. The two consecutive frame backlight signals include a target frame backlight signal and a non-target frame backlight signal, and the two consecutive frame display panel signals include a target frame display panel signal and a non-target frame display panel signal.

[0153] The target frame backlight signal and the target frame display panel signal both belong to the target frame, and the target frame backlight signal and the target frame display panel signal are regarded as a group of signals (hereinafter referred to as F group signal). The non-target frame backlight signal and the non-target frame display panel signal both belong to the non-target frame, and the non-target frame backlight signal and the non-target frame display panel signal are regarded as a group of signals (hereinafter referred to as G group signal).

[0154] After determining the two groups of signals, the display order of the two groups of signals can be determined, and the sorting manner can be random; in the display order from first to last, for example, it is {F group signal, G group signal}, for example, it is {G group signal, F group signal}. Taking the display order of {F group signal, G group signal} as an example to introduce the control process:

[0155] Table 3

[0156] Group F gray scale Group G gray scale Backlight signal Blue light White light Display panel signal - picture area 902 (0，0，255) (255，255，0) Display panel signal - picture area 901 (0，0，255) (0，0，255)

[0157] Referring to Table 3, the target frame backlight signal in the F group signal can set the gray scale of the picture area 901 and 902 to the gray scale value of blue light, such as (0, 0, 255); the target frame display panel signal in the F group signal can set the gray scale of the picture area 902 to (0, 0, 255) and the gray scale of the picture area 501 to (0, 0, 255). Thus, the target frame backlight signal in the F group signal can make the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly generate blue light, and the target frame display panel signal in the F group signal can make the blue light generated by the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly be transmitted, as shown in FIG. 5. Figure 17

[0158] The non-target frame backlight signal in the G group signal can set the gray scale of the picture area 901 and 902 to the gray scale value of white light, such as (255, 255, 255); the non-target frame display panel signal in the G group signal can set the gray scale of the picture area 902 to (255, 255, 0) and the gray scale of the picture area 501 to (0, 0, 255). Thus, the non-target frame backlight signal in the G group signal can make the backlight sources corresponding to the picture area 901 and the picture area 902 in the backlight assembly generate white light, and the non-target frame display panel signal in the G group signal can make the red light and the green light in the white light generated by the backlight source corresponding to the picture area 502 in the backlight assembly be transmitted, as shown in FIG. 6. Figure 17

[0159] The controller controls the backlight assembly according to the target frame backlight signal in the F group signal and controls the display panel according to the target frame display panel signal in the F group signal; thus, the backlight sources corresponding to the picture area 901 and the picture area 902 in the backlight assembly generate blue light, and the blue light generated by the backlight sources corresponding to the picture area 901 and the picture area 902 is transmitted.

[0160] Then, the controller controls the backlight assembly according to the non-target frame backlight signal in the G group signal and controls the display panel according to the non-target frame display panel signal in the G group signal; thus, the backlight sources corresponding to the picture area 901 and the picture area 902 in the backlight assembly generate white light, the blue light in the white light generated by the backlight source corresponding to the picture area 901 is transmitted, and the red light and the green light in the white light generated by the backlight source corresponding to the picture area 902 are transmitted.

[0161] Thus, for the user, the picture area 901 visually displays blue color, and the picture area 502 visually displays white color, which can not only ensure that the picture perceived by the user conforms to the picture shown in FIG. 5, but also can relieve the color cast problem and enhance the color gamut. Figure 9

[0162] ​​​In an embodiment, the display order of the target frame is the first display order in the at least two continuous frames.

[0163] Taking the two groups of signals as an example, the display order from the first to the last is, for example, {the group A signal, the group B signal}, or for example, {the group B signal, the group A signal}.

[0164] In the display order of {the group A signal, the group B signal}, the target frame is the first display order in the two continuous frames; in the display order of {the group B signal, the group A signal}, the target frame is the second display order in the two continuous frames.

[0165] In the display order of {the group A signal, the group B signal}, the group A signal is executed first, and the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly all generate red light, and the red light generated by the backlight sources corresponding to the picture area 501 and the picture area 502 is transmitted; at this time, the backlight sources all generate red light, and for the user, the red color is relatively prominent, and even if the user perceives that the picture area 502 is white later, because the red color is relatively prominent at the beginning, the user will feel that the color mixing phenomenon is not particularly obvious.

[0166] In the display order of {the group B signal, the group A signal}, the group B signal is executed first, and the backlight sources corresponding to the picture area 501 and the picture area 502 in the backlight assembly all generate white light, and the red light in the white light generated by the backlight source corresponding to the picture area 501 is transmitted, and the green light and the blue light in the white light generated by the backlight source corresponding to the picture area 502 are transmitted; at this time, the backlight sources all generate white light, and for the user, the red color is not particularly prominent, and the white color is relatively prominent, and even if the user perceives that the picture area 502 is white later, because the white color is relatively prominent at the beginning, the user will feel that the color mixing phenomenon is relatively particularly obvious.

[0167] Therefore, the display order of the target frame is the first display order in the at least two continuous frames, which is beneficial to alleviate the color mixing phenomenon perceived by the user.

[0168] In an embodiment, the controller is further configured to: determine the screen refresh rate according to the frame number of the backlight signal or the display panel signal; the frame number is positively correlated with the screen refresh rate; determine the time interval between adjacent two frames according to the screen refresh rate; and determine the time of the target frame or the time of the non-target frame according to the time interval between adjacent two frames.

[0169] Because the frame number of the backlight signal is consistent with the frame number of the display panel signal, the controller can determine the screen refresh rate according to the frame number of the backlight signal or the display panel signal; the frame number is positively correlated with the screen refresh rate, that is, the more the frame number, the higher the screen refresh rate. For example, the screen refresh rate corresponding to two frames is lower than the screen refresh rate corresponding to three frames.

[0170] The controller obtains the screen refresh rate after obtaining the screen refresh rate, which refers to the number of screen refreshes per second. Therefore, the interval duration between two adjacent frames can be determined according to the screen refresh rate. After determining the interval duration between two adjacent frames, the time point of the target frame or the time point of the non-target frame can be determined according to the interval duration between two adjacent frames. The difference between the time point of the target frame and the time point of the non-target frame is consistent with the interval duration between two adjacent frames.

[0171] Since the single-frame to-be-displayed picture is split into at least two continuous backlight signals and display panel signals in the present application, the screen refresh rate is determined according to the number of frames of the backlight signal or the display panel signal. The larger the number of frames, the higher the screen refresh rate, thereby avoiding the user's feeling of a broken picture and ensuring that the picture the user feels is consistent with the single-frame to-be-displayed picture.

[0172] In an embodiment, the time point of the target frame or the time point of the non-target frame is determined according to the interval duration between two adjacent frames, including: if the target frame is earlier than the non-target frame, the time point of the target frame is determined, and then the time point of the non-target frame is obtained according to the time point of the target frame and the interval duration between two adjacent frames; if the non-target frame is earlier than the target frame, the time point of the non-target frame is determined, and then the time point of the target frame is obtained according to the time point of the non-target frame and the interval duration between two adjacent frames.

[0173] Taking the two groups of signals described above as an example:

[0174] The display order from the first to the last is {A group of signals, B group of signals}, that is, the display order of the target frame is earlier than that of the non-target frame. In this scenario, after the time point of the target frame is determined, the time point of the target frame is added to the interval duration between two adjacent frames, and the result is taken as the time point of the non-target frame.

[0175] The display order from the first to the last is {B group of signals, A group of signals}, that is, the display order of the non-target frame is earlier than that of the target frame. In this scenario, after the time point of the non-target frame is determined, the time point of the non-target frame is added to the interval duration between two adjacent frames, and the result is taken as the time point of the target frame.

[0176] In the present embodiment, the time point of the target frame or the time point of the non-target frame can be more accurately determined according to the display order of the target frame and the non-target frame in combination with the interval duration between two adjacent frames.

[0177] In an embodiment, the controller is further configured to: obtain a first picture area brightness target value and a second picture area brightness target value associated with the to-be-displayed picture; perform brightness adjustment on a first picture area of the to-be-displayed picture according to the first picture area brightness target value; and perform brightness adjustment on a second picture area of the to-be-displayed picture according to the second picture area brightness target value.

[0178] For example,Figure 5 For example, for the red-white frame picture shown, the picture area 501 displays red in vision and the picture area 502 displays white in vision for the user according to the solution provided by the foregoing embodiments, which guarantees the picture perceived by the user to be consistent with the picture displayed by the display device and Figure 5 The picture shown is consistent, and the color bleeding problem is also alleviated, the color gamut is enhanced, the advantages of the RGB three-dimensional color control technology can be effectively exerted, and the displayed picture color is relatively uniform, and the level problem caused by uneven color transition after algorithm compensation can be effectively avoided. However, the luminance is reduced to some extent, and part of the luminance is sacrificed.

[0179] The first picture area luminance target value and the second picture area luminance target value associated with various pictures can be stored through a luminance recording table. The controller can determine a picture matched with the to-be-displayed picture in the luminance recording table, so as to obtain the first picture area luminance target value and the second picture area luminance target value associated with the to-be-displayed picture. The controller can send a corresponding signal to a component related to adjusting the first picture area luminance according to the first picture area luminance target value, so as to adjust the luminance of the first picture area of the to-be-displayed picture. The controller can send a corresponding signal to a component related to adjusting the second picture area luminance according to the second picture area luminance target value, so as to adjust the luminance of the second picture area of the to-be-displayed picture, so that the luminance of the to-be-displayed picture meets the requirements.

[0180] In addition, the controller can also combine HDR and other technologies to compensate for the luminance of the to-be-displayed picture, to make up for the sacrificed luminance. The English full name of HDR is High Dynamic Range, and the Chinese name is high dynamic range.

[0181] The luminance recording table can be generated in the following manner:

[0182] For a certain picture (such as a red-white frame picture), the picture can be displayed in the manner of the foregoing embodiments provided by the present application, and the picture can also be displayed in a traditional manner. The picture displayed in the manner of the foregoing embodiments provided by the present application can be referred to as a first display picture, and the picture displayed in the traditional manner can be referred to as a second display picture.

[0183] If the tester determines that the luminance of the first display picture does not reach the luminance of the second display picture, the tester can issue a first luminance enhancement instruction through the test control device. After receiving the first luminance enhancement instruction, the controller can perform luminance enhancement processing on the first picture area and the second picture area of the first display picture.

[0184] When the tester determines that the luminance of the first display picture reaches the luminance of the second display picture, the tester can send a luminance enhancement stop command through the test control device. After receiving the luminance enhancement stop command, the controller can stop the luminance enhancement processing of the first picture area and the second picture area of the first display picture, so that the luminance of the picture displayed in the manner of the above-mentioned embodiments of the present application is compensated. However, after the compensation, the color cast problem of the first display picture can become more obvious.

[0185] When the tester determines that the first display picture has color cast, the color cast is mainly caused by the second color of the second picture area exceeding the picture area thereof. At this time, the tester can send a second luminance reduction command through the test control device. After receiving the second luminance reduction command, the controller can perform luminance reduction processing on the second picture area of the first display picture, further visually relieve the color cast problem, and avoid the second color from being excessively diffused due to the excessively high luminance of the second picture area.

[0186] After the luminance reduction processing, if the tester determines that the first display picture will not have color cast, the tester can send a luminance reduction stop command through the test control device. After receiving the luminance reduction stop command, the controller stops the luminance reduction processing of the second picture area of the first display picture.

[0187] The controller obtains a single set of luminance test target values according to the current luminance value of the first picture area and the current luminance value of the second picture area of the first display picture.

[0188] The above-mentioned process can be repeated to obtain multiple sets of luminance test target values. The controller can process the multiple sets of luminance test target values by averaging to obtain the first picture area luminance target value and the second picture area luminance target value, and associate the first picture area luminance target value and the second picture area luminance target value to the picture.

[0189] For other pictures, the above-mentioned process can be performed to obtain the first picture area luminance target value and the second picture area luminance target value associated with the other pictures. The first picture area luminance target value and the second picture area luminance target value associated with each picture are stored in a table to form a luminance record table.

[0190] In the embodiment, the first picture area luminance target value and the second picture area luminance target value associated with the to-be-displayed picture can be obtained through the pre-configured luminance record table, so that the luminance of the to-be-displayed picture is adjusted to compensate for the sacrificed luminance.

Unless otherwise specified herein, the execution of the steps is not strictly limited in sequence, and the steps can be executed in other orders. Moreover, at least some of the steps in the flowcharts involved in the above embodiments can include multiple steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of the steps or stages is not necessarily sequential, but can be alternately or alternately executed with at least part of other steps or steps or stages in other steps.
