[0042] To make the objectives, embodiments, and advantages of this application clearer, the following will clearly and completely describe the exemplary embodiments of this application in conjunction with the accompanying drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only a part of the embodiments of this application, rather than all of the embodiments.

[0043] It should be noted that the brief description of the terms in this application is only for the convenience of understanding the embodiments described next, rather than intending to limit the embodiments of this application. Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0044] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover but not exclude inclusion. For example, a product or device comprising a series of components does not necessarily have to be limited to those components clearly listed, but may include other components not clearly listed or inherent to these products or devices.

[0045] Figure 1 It is a schematic diagram of the architecture of a display device based on backlight display technology. As Figure 1 shown, the display device may include: a processing module, an image display control module, a backlight control module, a display screen, and a backlight panel.

[0046] Among them, the above-mentioned processing module is used to obtain the video stream to be displayed, process the video stream, and then divide the processed video stream into image data and backlight data. The processing module can output the image data to the image display control module so that the image display control module can light up the display screen according to the image data; the processing module can output the backlight data to the backlight control module so that the backlight control module can light up the backlight panel according to the backlight data.

[0047] In some embodiments, the above-mentioned image display control module may be, for example, a Timing Controller (TCON), and the above-mentioned backlight control module may be, for example, a Backlight Controller (BCON). The above-mentioned processing module may be deployed with the core of the display device. The core may be, for example, a System on Chip (SOC).

[0048] The above display screen may include a liquid crystal display panel. With the development of liquid crystal display technology, different types of liquid crystal display panels have gradually increased. Currently, common liquid crystal display panels include, for example: Vertical Alignment (VA) liquid crystal display panels, In-Plane Switching (IPS) liquid crystal display panels, Twisted Nematic (TN) liquid crystal display panels, etc. Exemplarily, Figure 2 is a schematic diagram of an IPS liquid crystal display panel. As Figure 2 shown in the IPS liquid crystal display panel, the IPS liquid crystal display panel can also be called a hard screen. The IPS liquid crystal display panel can provide a wide viewing angle, but there is a problem of low contrast. As Figure 2 shown, the liquid crystal molecules 100 of the IPS liquid crystal display panel are parallel to the glass substrate (such as Figure 2 the electrode 200 shown in).

[0049] Figure 3 is a schematic diagram of a VA type liquid crystal display panel. As Figure 3 shown in the VA type liquid crystal display panel shown in, the VA type liquid crystal display panel can also be called a soft screen. As Figure 3 shown, the VA type liquid crystal panel can adopt the vertical alignment mode of negative liquid crystal. When no electric field is applied, the liquid crystal molecules 100 are "standing" perpendicular to the glass substrate (such as Figure 3 the electrode 200 shown in). When viewed straight on, the birefringence Δn is 0, and there is no birefringence at this time. Therefore, the dark field light leakage at this time only depends on the orthogonality of the upper and lower polarizers. For example, at a positive viewing angle, the orthogonality of the upper and lower polarizers is better, and the light leakage is the smallest, showing a dark state. As Figure 2 and Figure 3 shown, when a voltage is applied, an electric field can be formed between the electrodes 200 (such as Figure 2 and Figure 3 the E shown in. When a voltage is applied, the state of the liquid crystal molecules 100 is on, and when no voltage is applied, the state of the liquid crystal molecules 100 is off).

[0050] As the viewing angle increases, in the non-axial viewing angle direction, the effective orthogonality of the upper and lower polarizers decreases, so light leakage occurs, and Δn is no longer 0 in the side viewing angle direction. At this time, the existence of birefringence makes the outgoing light an elliptically polarized light. After passing through the filter layer and the polarizer, the light in the absorption axis direction is absorbed, and the component in the transmission axis direction passes through the polarizer, resulting in a light leakage phenomenon. And as the viewing angle gradually increases, Δn gradually increases, the degree of birefringence gradually increases, and the dark state light leakage becomes more obvious. Therefore, the VA type liquid crystal display panel can provide better contrast, but there is a problem of narrow viewing angle.

[0051] VA type panels are mainly VA type liquid crystal panels that use quantum dot backlight to improve color gamut, anti-glare, low reflective (AGLR) type to improve contrast, higher haze and lower reflectivity. However, the wavelength of quantum dot red light is relatively long, so when the quantum dot backlight is matched with the VA type panel of AGLR, the polarizer and panel containing low reflection (LR) will change the backlight phase difference, and serious red and purple phenomena will occur when viewed from the side. And when the light source is through the color filter (CF) layer, due to the step difference in CF film thickness and different liquid crystal tilting angles, there will be color shift when viewed from the side, and the color of the color shift will have different performances at different angles. In other words, at present, when the VA panel is matched with the backlight, due to the uniformity limitation of the panel process and the side viewing angle light leakage of the VA panel. There are often problems of black field color cast or black field color spots when viewed from the side. These problems will be magnified when using a high color gamut backlight, that is, there will be serious color cast and obvious color spots under black field. Therefore, the existing VA type LCD panel has the problem of black field side view color cast.

[0052] Currently, the existing method for reducing the side color cast when viewing a black field is mainly to turn off the backlight of the display device during a black field to avoid the side color cast when viewing a black field.

[0053] However, when using this existing method, there is a control timing requirement for the backlight to be turned off and then turned on. In scenes where the screen content changes quickly and the brightness switches quickly (such as the game interface), the existing method cannot be used due to the limitation of the timing control time.

[0054] In view of the above-mentioned problems existing in the existing display devices, the present application proposes a method that can reduce the black field side view color cast and reduce the timing control time, so as to improve the display accuracy and user experience of the display device.

[0055] It should be understood that the present application does not limit the application scenario of the display control method. The display control method can be applied to a display device using a display screen of a VA-type liquid crystal display, and can also be applied to a display device including other types of display screens, and the present application does not limit this. The present application does not limit the type of the display device. Exemplarily, the display device can be, for example, a television, a monitor, a touch panel, an intelligent electronic panel, a mobile phone, etc.

[0056] The following takes a display device including a processing module, an image display control module, and a display screen as an example, and describes the technical solution of the present application in detail in combination with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0057] Figure 4 A flowchart of a display control method provided for this application. As Figure 4 shown, the method may include the following steps:

[0058] S101. The processing module acquires the image data of the content to be displayed and outputs the image data to the image display control module of the display device.

[0059] In some embodiments, the processing module may be, for example, the core of the display device. The core may be, for example, a System on Chip (SOC). Optionally, this application does not limit the above-mentioned content to be displayed. For example, the content to be displayed may be any one of a video, a video stream, an image, etc. The implementation manner of the processing module acquiring the image data of the content to be displayed may refer to any existing method for determining the image data of the content to be displayed, which will not be elaborated here.

[0060] As mentioned above, the image display control module may be, for example, the TCON board of the display device.

[0061] S102. The processing module synchronizes the instruction to enter the first display mode to the image display control module in response to the instruction to enter the first display mode.

[0062] Exemplarily, the first display mode may be, for example, a large viewing angle mode. Optionally, the instruction for the first display mode may be triggered by the user, or may be automatically generated by the processing module according to the change speed of the content to be displayed on the display device, etc.

[0063] S103. The image display control module acquires the first preset data for determining the brightness of the display screen in response to the instruction to enter the first display mode.

[0064] Exemplarily, the first preset data may be, for example, pre-stored in the image display control module. Exemplarily, the first preset data for the brightness of the display screen may be, for example, the mapping relationship between the gray scale and the voltage. Since the brightness of the display screen is positively correlated with the voltage intensity applied to the display screen, the brightness of the display screen can be determined through the mapping relationship between the gray scale and the voltage.

[0065] Exemplarily, taking the first display mode as the large viewing angle mode as an example, the instruction to enter the first display mode indicates that the display screen is required to provide a wide viewing angle. Therefore, in the first display mode, it is necessary to reduce the color cast of the black field in the side view. Therefore, the image display control module can respond to the instruction to enter the first display mode, acquire the first preset data for image display, so that the probability of color cast of the black field can be reduced when viewing from a large viewing angle (side view), thereby improving the user experience.

[0066] S104. The image display control module controls the display screen to display the content to be displayed according to the first preset data and the above image data.

[0067] Among them, the brightness of the "target gray level in the image data" determined based on the first preset data is greater than the brightness of the "target gray level in the image data" determined based on the second preset data. The second preset data is the preset data used to determine the brightness of the display screen when the image display control module responds to the instruction to enter the second display mode and controls the display screen to display.

[0068] Optionally, the above second preset data can be, for example, pre-stored in the image display control module. In addition, it should be understood that this application does not limit when the display device responds to the above instruction to enter the second display mode and controls the display screen to display based on the second preset data.

[0069] Exemplarily, the above second display mode can be, for example, a non-large viewing angle mode. In some embodiments, the second display mode can be, for example, the default display mode preset by the display device.

[0070] Because the brightness of the "target gray level in the image data" determined based on the first preset data is greater than the brightness of the "target gray level in the image data" determined based on the second preset data, so the display control by the first preset data makes the brightness of the display device during black field display also higher than that during display control based on the second preset data. Therefore, the existence of the black field is avoided, and further the black field side view color cast is reduced.

[0071] Optionally, the image display control module can determine each gray level included in the image data after obtaining the above image data. Then, the image display control module can determine the voltage required to display the content to be displayed based on each gray level included in the image data and the first preset data. Then, the image display control module can control the display screen to perform image display based on the voltage. It should be understood that the specific implementation manner of the image display control module to control the display screen to display according to the first preset data and the above image data can refer to any existing image display method, and this application will not elaborate here.

[0072] In this embodiment, the display device can respond to an instruction to enter the first display mode through a processing module, and control the display screen to display an image through first preset data. Since the brightness of the target gray level in the image data determined based on the first preset data is greater than the brightness of the target gray level in the image data determined based on the second preset data, in the first display mode, the brightness of the black field displayed by the display device can also be increased, expanding the viewing angle range in which the display device can display colors normally without color cast, and thus reducing the black field color cast in the case of side viewing. Through the above method, while reducing the black field color cast in side viewing, the backlight of the display device does not need to be turned off, so the timing requirements for implementing the function of reducing the black field color cast in side viewing are reduced, the efficiency of implementing the function of reducing the black field color cast in side viewing is improved, and further, the display device can reduce the black field color cast in scenarios such as rapid change of the screen content and rapid switching of the brightness, improving the display accuracy and user experience of the display device.

[0073] As a possible implementation manner, the above first preset data may include, for example, a first mapping relationship between gray levels and voltages. The above second preset data may include, for example, a second mapping relationship between gray levels and voltages. Among them, the voltage corresponding to the target gray level in the first mapping relationship is greater than the voltage corresponding to the target gray level in the second mapping relationship.

[0074] Exemplarily, the above target gray level may be any gray level. Or, the target gray level may also be any gray level less than a preset gray level.

[0075] Taking the above target gray level as any gray level as an example, for any gray level in the first mapping relationship, the voltage corresponding to this gray level is greater than the voltage corresponding to this gray level in the second mapping relationship. In some embodiments, this voltage may also be referred to as the gamma voltage. Through the above method, in the first display mode, the overall display brightness of the display device can be adjusted, so that the overall brightness of the display device in the first display mode is higher than the overall brightness of the display device in the second display mode, improving the smoothness of the change in the brightness of the image displayed by the display device in the first display mode and further improving the user experience.

[0076] Taking any gray level less than the preset gray level as the target gray level, it should be understood that the present application does not limit the size of the above-mentioned preset gray level. Exemplarily, taking the preset gray level as the gray level of 2%, any gray level between 0-2% can be the target gray level less than the preset gray level. Generally, the display effect corresponding to the gray level of 0-2% can be regarded as the black field. That is to say, for any target gray level less than the preset gray level, it indicates that the display effect of the display device corresponding to this target gray level is the black field. That is to say, when the display device displays this target gray level, the problem of side-view color cast will occur. Since the magnitude of the voltage corresponding to the gray level is positively correlated with the display brightness, therefore, through "any target gray level less than the preset gray level in the first mapping relationship, the voltage corresponding to this target gray level is greater than the voltage corresponding to this gray level in the second mapping relationship", the brightness of the display device when performing black field display based on this first mapping relationship is higher than that when performing black field display based on this second mapping relationship. Therefore, the existence of the black field is avoided, and thus the side-view color cast of the black field is reduced.

[0077] It should be understood that for any gray level greater than or equal to the preset gray level in the first mapping relationship, the voltage corresponding to this gray level can be the same as or different from the voltage corresponding to this gray level in the second mapping relationship, and the present application does not limit this. Or, for any gray level greater than or equal to the preset gray level in the first mapping relationship, the voltage corresponding to this gray level can refer to any existing mapping relationship between the gray level and the voltage, and the present application does not limit this.

[0078] In some embodiments, the voltages corresponding to any target gray level less than the preset gray level in the first mapping relationship can all be equal to the voltage corresponding to the preset gray level. Among them, the voltage corresponding to the preset gray level in the second mapping relationship can be equal to the voltage corresponding to the preset gray level in the first mapping relationship. For any one of the second mapping relationship and the first mapping relationship, the magnitude of the gray level in this mapping relationship can be positively correlated with the magnitude of the voltage value. Therefore, when the voltage corresponding to the preset gray level in the second mapping relationship is equal to the voltage corresponding to the preset gray level in the first mapping relationship, the voltages corresponding to the target gray levels less than the preset gray level in the first mapping relationship all satisfy being greater than the voltages corresponding to the target gray levels less than the preset gray level in the second mapping relationship. Through the above method, it is ensured that the voltage corresponding to any target gray level less than the preset gray level in the first mapping relationship is greater than the voltage corresponding to this target gray level in the second mapping relationship.

[0079] In some embodiments, the above-mentioned first preset data or second preset data may also include other data for determining the brightness of the display screen, and the present application does not limit this.

[0080] The following will detail how the processing module obtains the above-mentioned instruction to enter the first display mode:

[0081] As a possible implementation, the display device can receive the above instruction for entering the first display mode input by the user. For example, before the processing module synchronizes the instruction for entering the first display mode to the image display control module in response to the instruction for entering the first display mode, it can also respond to the instruction for the user to open the function setting interface and control the display screen to display the function setting interface. Then, the processing module can receive the instruction for entering the first display mode input by the user through this function setting interface.

[0082] Exemplarily, Figure 5 is a schematic diagram of a display interface provided by the present application. As Figure 5 shown, the processing module can respond to the instruction for the user to trigger and open this function setting interface and display the function setting interface.

[0083] It should be understood that the present application does not limit how the processing module receives the instruction for the user to trigger and open the above function setting interface. Exemplarily, for example, the processing module can determine that the user has triggered the above instruction for opening the function setting interface through the touch signal triggered by the user through a touch object (such as a finger or a stylus, etc.). Or, the processing module can also receive the remote control signal triggered by the user through a remote control device (such as a remote controller, etc.) and determine that the user has triggered the above instruction for opening the function setting interface. Or, for another example, the user can also trigger the above instruction for opening the function setting interface through voice control or the like.

[0084] Exemplarily, taking Figure 5 as an example, the processing module can determine that it has received the instruction for the user to enter the first display mode when the user clicks on the control for entering the first display mode (such as Figure 5 clicking "Yes" in ).

[0085] Optionally, further, the processing module can, for example, also receive the instruction for the user to close the first display mode through this function setting interface. The processing module can respond to this instruction for closing the first display mode, obtain the above second preset data, and based on this second preset data, control the display screen to perform image display.

[0086] In this embodiment, the processing module can receive the instruction for the user to enter the first display mode through the function setting interface. That is, the user can, in the settings of the display device, turn on the first display mode of the display device so that subsequent display settings continue to use the above first preset data for image display until the display device receives the instruction for closing the first display mode. Through the above method, the operation difficulty for the display device to achieve reducing the side-view black field color cast is reduced, the flexibility of the display device is improved, and the user experience is improved.

[0087] As another possible implementation, the display device may further include, for example: a target interface. An electronic device other than the display device may be connected to the display device through the target interface.

[0088] It should be understood that the type of the above-mentioned electronic device is not limited in this application. Exemplarily, the electronic device may be, for example, any electronic device capable of outputting a display signal, such as a game device, a computer, etc. Exemplarily, the above-mentioned target interface may be, for example, a High Definition Multimedia Interface (HDMI), etc.

[0089] In this implementation, before the processing module synchronizes the instruction to enter the first display mode to the image display control module in response to the instruction to enter the first display mode, it may also control the display screen to display a prompt message for prompting the user whether to enable the first display mode when it detects that the display device is connected to the above-mentioned electronic device through the target interface. Then, the processing module may receive the above-mentioned instruction to enter the first display mode input by the user based on the prompt message.

[0090] Exemplarily, the processing module may determine that it detects the connection of the target interface to the above-mentioned electronic device by changing the interface voltage to a preset voltage value.

[0091] Exemplarily, taking the above-mentioned electronic device as a game device as an example, Figure 6 is a schematic diagram of another display interface provided by this application. As Figure 6 shown, the processing module may display the above-mentioned prompt message when the target interface of the display device is connected to the game device. If the user clicks "Yes", the processing module may determine that it receives the instruction to enter the first display mode.

[0092] Alternatively, if the processing module receives the instruction from the user not to enter the first display mode based on the prompt message, the processing module may, for example, continue to control the display screen to perform image display based on the second preset data.

[0093] In this embodiment, the display device may display the above-mentioned "prompt message for prompting the user whether to enable the first display mode" after the external electronic device is connected to the display device, so that the user can select whether the display device enters the first display mode after connecting the electronic device, expanding the application scenario of the large viewing angle display mode and further improving the user experience.

[0094] As another possible implementation, the processing module can also automatically generate and respond to the above instruction to enter the first display mode. For example, before synchronizing the instruction to enter the first display mode to the image display control module in response to the instruction to enter the first display mode, the processing module can obtain the brightness values corresponding to multiple frames of content to be displayed. Then, the processing module can determine the brightness change frequency of the display screen according to the brightness values corresponding to the multiple frames of content to be displayed.

[0095] Exemplarily, a mapping relationship between image gray levels and brightness can be pre-stored in the processing module. For example, the processing module can determine the brightness value corresponding to the content to be displayed based on the gray level of the content to be displayed and the mapping relationship between the gray level and brightness.

[0096] Optionally, the processing module can first determine whether there is a change in brightness value between two adjacent frames of content to be displayed, and when it is determined that there is a change in brightness value, determine the brightness change frequency.

[0097] If the above brightness change frequency is greater than or equal to the preset frequency, it indicates that the brightness of the content displayed by the display device changes rapidly, so the required time for the brightness of the backlight to change is short. Then, the existing method of avoiding color cast on the black field side view by turning off the backlight is no longer applicable, and the processing module can generate and respond to the instruction to enter the first display mode to control the display screen to perform image display through the first preset data.

[0098] If the above brightness change frequency is less than the above preset frequency, it indicates that the brightness of the content displayed by the display device changes slowly, so the required speed for the brightness of the backlight to change is low. Optionally, the processing module can enter the first display mode and control the display screen to perform image display through the first preset data. Or, the processing module can also continue to control the display screen to perform image display according to the second preset data.

[0099] In this embodiment, when the brightness of the display content changes rapidly, the display device can promptly switch to the first display mode and control the display screen to perform image display through the first preset data, improving the timeliness of the display device to reduce color cast on the black field side view, and further improving the display accuracy and user experience.

[0100] As a possible implementation, the processing module can also respond to the power-on instruction, obtain a preset image of "any gray level not including less than the preset gray level", and control the display screen to display the preset image.

[0101] Exemplarily, the preset gray level can refer to the preset gray level described in any of the foregoing embodiments, which will not be elaborated here.

[0102] Optionally, the preset image can be, for example, pre-stored in the processing module. The processing module can, for example, respond to the operation of the user triggering the power-on control of the display device, respond to the power-on instruction, and obtain the above preset image.

[0103] Since the above preset image does not include any gray level less than the preset gray level, that is, the preset image does not include the gray level that will cause the display screen to display a black field, the problem of black field side-view color deviation during the startup process of the display device is avoided, and the color rendering accuracy and user experience during the startup process of the display device are improved.

[0104] Optionally, the method for the display device to control the display screen to display the preset image can refer to any existing method for image display during the startup process, which will not be elaborated here.

[0105] In this embodiment, considering that the display device may have the situation of black field side-view color deviation during the startup process due to reasons such as the first preset data not being loaded yet, etc., therefore, by displaying the above preset image of "not including any gray level less than the preset gray level" during the startup process, the problem of black field side-view color deviation during the startup process of the display device is avoided, and the color rendering accuracy and user experience during the startup process of the display device are further improved.

[0106] Taking the above electronic device as a game device as an example, Figure 7 This is a schematic diagram of the architecture of another display device provided by the present application. As Figure 7 shown, when the game device is connected, the movement 706 of the display device can determine to switch to the game mode (i.e., switch to the first display) input. As Figure 7 shown, between the main board 707 and the TCON board 703, and between the TCON board 703 and the Source board 702 (which can also be called the liquid crystal panel source driver board), they can be connected through high-speed signal lines 705. The display screen can include a liquid crystal screen panel 701.

[0107] Based on the display device as Figure 7 shown, Figure 8 This is a schematic flowchart of another display control method provided by the present application. As Figure 8 shown, taking this display device as a TV as an example, the movement 706 of the TV can determine whether it is in the game mode. If so, the movement 706 can send a display pop-up window signal and a software selection function, so that an operation selection can pop up on the display interface, enabling the user to select whether to operate at a large viewing angle. For example, the user can select the yes / no option in the pop-up window through the remote control.

[0108] If the user selects to enable the first display mode through a pop-up window, the movement 706 can send a signal to enable the first display mode to the display TCON IC704. The TCON IC704 can call the abnormal drive signal (i.e., the aforementioned first mapping relationship), and then the panel can receive the TCON voltage signal and perform a specific gray-scale display. Among them, the TCON IC704 can perform special voltage drive processing on the 0-2% gray scale in all pictures after identifying the signal. For example, this processing method can be to pre-configure a new voltage table for adjusting the gray scale (referred to as the ACC table) for the TCON IC704, that is, the aforementioned first mapping relationship. Different from the normal table (i.e., the aforementioned second mapping relationship), the voltage of the new ACC Table at 0-2% can be set to the voltage of 2%. In this way, the TCON IC704 can directly call this table to complete the special voltage adjustment scheme. It can also be improved by another set of Gamma voltages. For example, for any gray scale in the aforementioned first mapping relationship, the voltage corresponding to this gray scale can be greater than the voltage corresponding to this gray scale in the second mapping relationship.

[0109] By actively changing the 0-2% gray scale to 2% gray scale, taking the VA panel as an example, the liquid crystal deflects partially, the component of birefringence in the front view direction increases, and when viewed from the side, the component in the direction of the transmission axis decreases, the chromaticity change with the viewing angle ratio shrinks, and the color cast problem weakens. The inventor found through research that the black field light leakage of the VA panel basically remains at 0.1nits or below. When the gray scale is set at 2%-3%, the front view light leakage will be between 0.25-0.35nits. This degree of light leakage is still lower than that of a normal IPS panel and has little impact on user use.

[0110] If the user selects not to enable the first display mode through a pop-up window, as Figure 8 shown, the movement 706 can transmit the signal of not enabling the first display mode to the TCON, so that the TCON can call the normal drive voltage (i.e., the aforementioned second mapping relationship). Or, if the movement 706 determines that it is not in the game mode, the movement 706 can transmit the signal of not being in the game mode to the TCON, so that the TCON can call the normal drive voltage. The panel can receive the TCON voltage signal and display normally.

[0111] In some embodiments, the boot interface of the display device can be a graphics card built into the software. This graphics card can be a 2% black gray scale graphics card.

[0112] In this embodiment, by performing image display based on the above first mapping relationship, compared with the existing VA liquid crystal display, the present application improves the color cast of the VA panel under the black field and reduces the subjective color cast problem in the side view in some modes. Through the increase of software functions, the present invention improves the side view color cast problem of the VA panel under the black field and enhances the user experience.

[0113] The present application also provides a computer-readable storage medium, which may include: various media that can store program codes, such as USB flash drives, mobile hard disks, read-only memories (ROMs), random access memories (RAMs), magnetic disks, or optical discs.
