[0006] Acquire image data of the content to be displayed, and output the image data to the image display control module;

[0007] In response to an instruction to enter the first display mode, the instruction to enter the first display mode is synchronized to the image display control module;

[0008] The image display control module is configured as follows:

[0009] In response to the instruction to enter the first display mode, first preset data for determining the brightness of the display screen is obtained, and the display screen is controlled to display the content to be displayed based on the first preset data and the image data;

[0010] Wherein, the brightness of the target grayscale in the image data determined based on the first preset data is greater than the brightness of the target grayscale in the image data determined based on the second preset data; the second preset data is the preset data used by the image display control module to control the display screen to display when responding to the instruction to enter the second display mode, for determining the brightness of the display screen.

[0011] In some embodiments, the first preset data includes: a first mapping relationship between grayscale and voltage; the second preset data includes: a second mapping relationship between grayscale and voltage; the voltage corresponding to the target grayscale in the first mapping relationship is greater than the voltage corresponding to the target grayscale in the second mapping relationship.

[0012] In some embodiments, the target gray level is any gray level; or, the target gray level is any gray level smaller than a preset gray level.

[0013] In some embodiments, 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 is further configured to:

[0014] In response to a user's instruction to open the function settings interface, control the display screen to show the function settings interface;

[0015] The function settings interface receives the user's instruction to enter the first display mode.

[0016] In some embodiments, the display device further includes: a target interface; an electronic device can be connected to the display device via the target interface; 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 is further configured to:

[0017] When it is detected that the display device is connected to the electronic device through the target interface, the display screen is controlled to display a prompt message to prompt the user whether to enable the first display mode;

[0018] Receive the user's instruction to enter the first display mode based on the prompt information.

[0019] In some embodiments, 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 is further configured to:

[0020] Obtain the brightness values ​​corresponding to the content to be displayed in multiple frames;

[0021] The brightness change frequency of the display screen is determined based on the brightness values ​​corresponding to the content to be displayed in multiple frames.

[0022] When the brightness change frequency is greater than or equal to a preset frequency, the instruction to enter the first display mode is generated.

[0023] In some embodiments, the processing module is further configured to:

[0024] In response to the power-on command, a preset image is acquired; the preset image does not include any gray level smaller than a preset gray level;

[0025] Control the display screen to show the preset image.

[0026] Secondly, this application provides a display control method, the method comprising:

[0027] The processing module of the display device acquires image data of the content to be displayed and outputs the image data to the image display control module of the display device; and, in response to an instruction to enter a first display mode, the instruction to enter the first display mode is synchronized to the image display control module.

[0032] The display device, display control method, storage medium, and program product provided in this application allow the display device to respond to an instruction to enter a first display mode via a processing module, and control the display screen to display images based on first preset data. Because the brightness of the target grayscale in the image data determined based on the first preset data is greater than the brightness of the target grayscale in the image data determined based on second preset data, the brightness of the black level displayed by the display device can also be increased in the first display mode. This expands the viewing angle range for normal color display without color cast, thereby reducing black level color cast when viewed from the side. Through the above method, while reducing black level color cast when viewed from the side, it is not necessary to turn off the backlight of the display device. Therefore, the timing requirements for implementing the function of reducing black level color cast when viewed from the side are reduced, and the efficiency of reducing black level color cast when viewed from the side is improved. This enables the display device to reduce black level color cast when the screen content changes rapidly and the brightness switches rapidly, improving the display accuracy and user experience of the display device.

[0042] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

[0043] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0044] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.

[0045] Figure 1 This is a schematic diagram of the architecture of a display device based on backlight display technology. Figure 1 As 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] The aforementioned processing module acquires the video stream to be displayed, processes the video stream, and then divides the processed video stream into image data and backlight data. This processing module can output the image data to the image display control module, enabling the image display control module to illuminate the display screen based on the image data; the processing module can also output the backlight data to the backlight control module, enabling the backlight control module to illuminate the backlight panel based on the backlight data.

[0047] In some embodiments, the image display control module may be, for example, a timing controller (TCON), and the backlight control module may be, for example, a backlight controller (BCON). The processing module may house the chassis of the display device. This chassis may be, for example, a system-on-a-chip (SOC).

[0048] The aforementioned display screen may include a liquid crystal display panel. With the development of liquid crystal display technology, different types of liquid crystal display panels are gradually increasing. Currently, common liquid crystal display panels include, for example, vertical alignment (VA) liquid crystal display panels, in-plane switching (IPS) liquid crystal display panels, and twisted nematic (TN) liquid crystal display panels. For example, Figure 2 This is a schematic diagram of an IPS liquid crystal display panel. Figure 2 The IPS LCD panel shown is also known as a hard screen. IPS LCD panels offer wide viewing angles but suffer from lower contrast. For example... Figure 2 As shown, the liquid crystal molecules 100 and the glass substrate (such as...) of the IPS liquid crystal display panel Figure 2 The electrodes 200 shown are parallel.

[0049] Figure 3 This is a schematic diagram of a VA-type liquid crystal display panel. Figure 3 The VA-type liquid crystal display panel shown is also known as a soft screen. Figure 3 As shown, VA-type liquid crystal panels can employ a vertical alignment method using negative liquid crystals. When no electric field is applied, the liquid crystal molecules 100 are perpendicular to the glass substrate (e.g., Figure 3 The electrode 200 shown is "standing upright." When viewed directly, its birefringence Δn is 0, meaning no birefringence occurs. Therefore, light leakage in the dark field depends only on the orthogonality of the upper and lower polarizers. For example, at a direct viewing angle, the orthogonality of the upper and lower polarizers is good, resulting in minimal light leakage and a dark state. Figure 2 and Figure 3 As shown, an electric field can be formed between electrodes 200 when a voltage is applied (e.g., ... Figure 2 and Figure 3 As shown in the diagram, when a voltage is applied, the liquid crystal molecule 100 is in an "on" state, and when no voltage is applied, the liquid crystal molecule 100 is in a "off" state.

[0050] As the viewing angle increases, the effective orthogonality of the upper and lower polarizers decreases in the non-axial viewing direction, resulting in light leakage. Furthermore, in the side viewing direction, Δn is no longer zero. The presence of birefringence at this point causes the outgoing light to be elliptically polarized. After passing through the filter layer and polarizer, light along the absorption axis is absorbed, while the component along the transmission axis passes through the polarizer, causing light leakage. Moreover, as the viewing angle gradually increases, Δn gradually increases, the degree of birefringence gradually increases, and light leakage in the dark state becomes more pronounced. Therefore, while VA-type LCD panels can provide good contrast, they suffer from a narrow viewing angle.

[0051] VA-type panels primarily utilize quantum dot backlighting to enhance color gamut and achieve anti-glare, low-reflective (AGLR) properties, thereby improving contrast, reducing haze, and lowering reflectivity. However, the wavelength of quantum dot red light is relatively long. Therefore, when using a quantum dot backlight with an AGLR VA panel, both the low-reflective (LR) polarizer and the panel itself alter the backlight phase difference, resulting in a severe reddish-purple tint when viewed from the side. Furthermore, as the light source passes through the color filter (CF) layer, variations in CF film thickness and different liquid crystal tilt angles lead to color shift when viewed from the side, with the shifted color appearing differently at different angles. In other words, currently, when VA panels are paired with backlighting, due to limitations in panel manufacturing uniformity and light leakage issues at side viewing angles, black level color shift or black level color spots often occur when viewed from the side. These problems are amplified when using high color gamut backlighting, resulting in severe color shift and noticeable color spots at black levels. Therefore, existing VA-type LCD panels suffer from color shift issues when viewed from the side at black levels.

[0052] Currently, the main method to reduce side-view color cast at black levels is to turn off the backlight of the display device during black levels to avoid side-view color cast at black levels.

[0053] However, when using the existing method, there are timing requirements for controlling the backlight's transition from being off to being on again. In scenarios with rapid changes in screen content and quick brightness switching (such as game interfaces), the existing method cannot be used due to the time constraints of the timing control.

[0054] In view of the aforementioned problems of existing display devices, this application proposes a method that can reduce side-view color shift in black levels and reduce timing control time, so as to improve the display accuracy and user experience of display devices.

[0055] It should be understood that this application does not limit the application scenario of the display control method. This display control method can be applied to display devices using VA-type liquid crystal displays, or to display devices including other types of displays; this application does not limit its application in this regard. This application also does not limit the type of display device. For example, the display device may be a television, monitor, touch panel, smart electronic panel, mobile phone, etc.

[0056] The technical solution of this application will be described in detail below using a display device including a processing module, an image display control module, and a display screen as an example, in conjunction with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0057] Figure 4 This is a flowchart illustrating a display control method provided in this application. Figure 4 As 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 chassis of a display device. The chassis may be, for example, a system-on-chip (SOC). Optionally, this application does not limit the content to be displayed. For example, the content to be displayed may be any displayable content such as video, video stream, or image. The implementation method of the processing module obtaining image data of the content to be displayed can refer to any existing method for determining image data of the content to be displayed, and will not be elaborated here.

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

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

[0062] For example, the first display mode may be a wide viewing angle mode. Optionally, the instruction for the first display mode may be triggered by the user, or it may be automatically generated by the processing module based on factors such as the speed of change of the content to be displayed on the display device.

[0063] S103, The image display control module responds to the instruction to enter the first display mode and obtains the first preset data used to determine the brightness of the display screen.

[0064] For example, the first preset data may be pre-stored in the image display control module. For example, the first preset data for display brightness may be a grayscale-voltage mapping relationship. Because the brightness of the display is positively correlated with the voltage intensity applied to the display, the brightness of the display can be determined through this grayscale-voltage mapping relationship.

[0065] For example, taking the first display mode as a wide viewing angle mode, the instruction to enter the first display mode indicates that the display screen needs to provide a wide viewing angle. Therefore, in the first display mode, it is necessary to reduce the black field side view color distortion. Therefore, the image display control module can respond to the instruction to enter the first display mode, obtain the first preset data for image display, so that the probability of black field color distortion can be reduced when the display is viewed from the side at a wide viewing angle, thereby improving the user experience.

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

[0067] The brightness of the target grayscale in the image data, determined based on the first preset data, is greater than the brightness of the target grayscale in the image data, determined based on the second preset data. The second preset data is the preset data used by the image display control module to determine the display screen brightness when responding to an instruction to enter the second display mode.

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

[0069] For example, the second display mode described above may be a non-wide viewing angle mode. In some embodiments, the second display mode may be a default display mode preset by the display device.

[0070] Because the brightness of the target grayscale in the image data determined based on the first preset data is greater than the brightness of the target grayscale in the image data determined based on the second preset data, the display control is performed using the first preset data, so that the brightness of the display device when displaying a black field is also higher than the brightness when display control is performed based on the second preset data. Therefore, the existence of a black field is avoided, thereby reducing the side-view color shift of the black field.

[0071] Optionally, after acquiring the aforementioned image data, the image display control module can determine the various gray levels included in the image data. Then, based on the various gray levels included in the image data and the first preset data, the image display control module can determine the voltage required to display the content to be displayed. Then, based on the voltage, the image display control module can control the display screen to display the image. It should be understood that the specific implementation of the image display control module controlling the display screen to display based on the first preset data and the aforementioned image data can refer to any existing image display method, and will not be elaborated further in this application.

[0072] In this embodiment, the display device can respond to the instruction to enter the first display mode through the processing module and control the display screen to display images through the first preset data. Because the brightness of the target grayscale in the image data determined based on the first preset data is greater than the brightness of the target grayscale in the image data determined based on the second preset data, the brightness of the black field displayed by the display device can also be increased in the first display mode. This expands the viewing angle range for normal color display without color cast, thereby reducing the black field color cast when viewed from the side. Through the above method, while reducing the black field color cast when viewed from the side, it is not necessary to turn off the backlight of the display device. Therefore, the timing requirements for implementing the function of reducing the black field color cast when viewed from the side are reduced, and the efficiency of reducing the black field color cast when viewed from the side is improved. This enables the display device to reduce the black field color cast when the screen content changes rapidly and the brightness switches rapidly, thereby improving the display accuracy and user experience of the display device.

[0073] As one possible implementation, the first preset data may include, for example, a first mapping relationship between grayscale and voltage. The second preset data may include, for example, a second mapping relationship between grayscale and voltage. Wherein, the voltage corresponding to the target grayscale in the first mapping relationship is greater than the voltage corresponding to the target grayscale in the second mapping relationship.

[0074] For example, the target gray level can be any gray level. Alternatively, the target gray level can also be any gray level smaller than a preset gray level.

[0075] Taking any gray level as an example, for any gray level in the first mapping relationship, the voltage corresponding to that gray level can be greater than the voltage corresponding to that gray level in the second mapping relationship. In some embodiments, this voltage can also be called gamma voltage. Using the above method, the overall display brightness of the display device can be adjusted in the first display mode, making the overall brightness of the display device in the first display mode higher than that in the second display mode. This improves the smoothness of brightness changes in the image displayed by the display device in the first display mode, further enhancing the user experience.

[0076] Taking any gray level smaller than a preset gray level as an example, it should be understood that this application does not limit the size of the preset gray level. For example, if the preset gray level can be a 2% gray level, the target gray level smaller than the preset gray level can be any gray level between 0% and 2%. Generally, the display effect corresponding to a gray level between 0% and 2% can be considered a black level. That is to say, for any target gray level smaller than the preset gray level, it means that the display effect of the display device corresponding to the target gray level is a black level. In other words, when the display device displays the target gray level, a side-view color shift problem will occur. Because the magnitude of the voltage corresponding to the gray level is positively correlated with the display brightness, by "any target gray level smaller than the preset gray level in the first mapping relationship, the voltage corresponding to the target gray level is greater than the voltage corresponding to the gray level in the second mapping relationship", the brightness of the display device when displaying a black level based on the first mapping relationship is increased compared to the brightness when displaying a black level based on the second mapping relationship, thus avoiding the existence of a black level and thereby reducing the side-view color shift of the black level.

[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 that gray level may be the same as or different from the voltage corresponding to that gray level in the second mapping relationship described above, and this application does not impose any limitation on this. Alternatively, for any gray level greater than or equal to the preset gray level in the first mapping relationship, the voltage corresponding to that gray level may refer to any existing gray level and voltage mapping relationship, and this application does not impose any limitation on this.

[0078] In some embodiments, the voltage corresponding to any target gray level smaller than a preset gray level in the first mapping relationship can be equal to the voltage corresponding to the preset gray level. 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 either the second or first mapping relationship, the gray level size can be positively correlated with 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 voltage corresponding to any target gray level smaller than the preset gray level in the first mapping relationship is greater than the voltage corresponding to any target gray level smaller than the preset gray level in the second mapping relationship. This method ensures that the voltage corresponding to any target gray level smaller than the preset gray level in the first mapping relationship is greater than the voltage corresponding to that target gray level in the second mapping relationship.

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

[0080] The following is a detailed explanation of how the processing module obtains the instruction to enter the first display mode:

[0081] As one possible implementation, the display device can receive the user's 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, the processing module can also respond to the user's instruction to open the function settings interface and control the display screen to show the function settings interface. Then, the processing module can receive the user's instruction to enter the first display mode through this function settings interface.

[0082] For example, Figure 5 This is a schematic diagram of a display interface provided in this application. (For example...) Figure 5 As shown, the processing module can respond to the user's command to open the function settings interface and display the function settings interface.

[0083] It should be understood that this application does not limit how the processing module receives the user's instruction to open the aforementioned function settings interface. For example, the processing module may determine that the user has triggered the instruction to open the aforementioned function settings interface through a touch signal triggered by a touch object (such as a finger or stylus). Alternatively, the processing module may also determine that the user has triggered the instruction to open the aforementioned function settings interface by receiving a remote control signal triggered by a remote control device (such as a remote control). Furthermore, the user may also trigger the instruction to open the aforementioned function settings interface through voice control or other means.

[0084] For example, with Figure 5 For example, the processing module can respond when the user clicks on a control that enters the first display mode (e.g., ...). Figure 5 Click "Yes" to confirm that the user's instruction to enter the first display mode has been received.

[0085] Optionally, the processing module can further receive a user-input command to turn off the first display mode through the function settings interface. In response to this command, the processing module can obtain the aforementioned second preset data and, based on this second preset data, control the display screen to display an image.

[0086] In this embodiment, the processing module can receive a user's command to enter the first display mode through the function settings interface. That is, the user can enable the first display mode of the display device in its settings, so that subsequent display settings will continue to use the aforementioned first preset data for image display until the display device receives a command to disable the first display mode. This method reduces the operational difficulty of reducing side-view black level color cast in the display device, improves the flexibility of the display device, and enhances the user experience.

[0087] As another possible implementation, the display device may also include, for example, a target interface. Electronic devices other than the display device can connect to the display device through the target interface.

[0088] It should be understood that this application does not limit the type of the aforementioned electronic device. For example, the electronic device may be any type of electronic device capable of outputting display signals, such as a gaming device or a computer. For example, the target interface may be, for example, a High Definition Multimedia Interface (HDMI).

[0089] In this implementation, before synchronizing the command to enter the first display mode to the image display control module, the processing module can also control the display screen to display a prompt message asking the user whether to enable the first display mode when it detects that the display device is connected to the aforementioned electronic device through the target interface. Then, the processing module can receive the user's command to enter the first display mode based on the prompt message.

[0090] For example, the processing module can determine that the target interface is connected to the aforementioned electronic device by changing the interface voltage to a preset voltage value.

[0091] For example, taking the aforementioned electronic device as a gaming device, Figure 6 A schematic diagram illustrating another display interface provided in this application. For example... Figure 6 As shown, the processing module can display the above prompt information when the target interface of the display device is connected to the game device. If the user clicks "Yes", the processing module can determine that it has received an instruction to enter the first display mode.

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

[0093] In this embodiment, after an external electronic device is connected to the display device, the display device can display the above-mentioned "prompt information for prompting the user whether to enable the first display mode", so that the user can choose whether the display device enters the first display mode after connecting the electronic device, thereby expanding the application scenarios of the wide 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 aforementioned command to enter the first display mode. For example, before synchronizing the command to enter the first display mode to the image display control module in response to the command, the processing module can also acquire 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 based on the brightness values ​​corresponding to the multiple frames of content to be displayed.

[0095] For example, the processing module may pre-store the mapping relationship between image grayscale and brightness. The processing module may determine the brightness value corresponding to the content to be displayed based on the grayscale of the content to be displayed and the mapping relationship between the grayscale and brightness.

[0096] Optionally, the processing module may 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 frequency of brightness change.

[0097] If the brightness change frequency is greater than or equal to the preset frequency, it indicates that the brightness of the content displayed on the display device changes rapidly. Therefore, the time required for the backlight brightness change is shorter. In this case, the existing method of avoiding side-view color distortion in black fields by turning off the backlight is no longer applicable. The processing module can then generate and respond to the instruction to enter the first display mode, and control the display screen to display images through the first preset data.

[0098] If the brightness change frequency is less than the preset frequency, it indicates that the brightness change of the displayed content is slow. Therefore, the backlight brightness change speed is required to be low. Optionally, the processing module can enter the first display mode and control the display screen to display images based on the first preset data. Alternatively, the processing module can continue to control the display screen to display images based on the second preset data.

[0099] In this embodiment, the display device can switch to the first display mode in a timely manner when the brightness of the displayed content changes rapidly. By controlling the display screen to display images through the first preset data, the display device can improve the timeliness of reducing side-view color distortion in black levels, and further improve the accuracy of display and user experience.

[0100] As one possible implementation, the processing module can also respond to the power-on command, obtain a preset image that "does not include any gray level smaller than the preset gray level", and control the display screen to display the preset image.

[0101] For example, the preset grayscale can refer to the preset grayscale described in any of the foregoing embodiments, and will not be repeated here.

[0102] Optionally, the preset image may be, for example, pre-stored in the processing module. The processing module may, for example, respond to a user's operation of triggering the power-on control of the display device, respond to a power-on command, and obtain the aforementioned preset image.

[0103] Because the preset image does not include any gray level smaller than the preset gray level, that is, the preset image does not include any gray level that would cause the display screen to show a black field, the problem of black field side-view color distortion during the power-on process of the display device is avoided, thus improving the accuracy of color display and user experience during the power-on process of the display device.

[0104] Optionally, the display device can control the display screen to display the preset image in any existing way that displays images during the power-on process, which will not be described in detail here.

[0105] In this embodiment, considering that the display device may exhibit black field side-view color distortion due to reasons such as the first preset data not being loaded during the power-on process, the problem of black field side-view color distortion during the power-on process is avoided by displaying the aforementioned preset image "excluding any gray level smaller than the preset gray level" during the power-on process, thereby further improving the accuracy of color display and user experience during the power-on process.

[0106] Taking the aforementioned electronic devices as gaming devices as an example, Figure 7 A schematic diagram of the architecture of another display device provided in this application. For example... Figure 7 As shown, the display device's mechanism 706 can determine the input to switch game modes (i.e., switch to the first display) when a game device is connected. For example... Figure 7 As shown, the main board 707 and the TCON board 703, as well as the TCON board 703 and the Source board 702 (also known as the LCD panel source driver board), can be connected via a high-speed signal line 705. The display screen may include an LCD panel 701.

[0107] Based on such Figure 7 The display device shown, Figure 8 A flowchart illustrating another display control method provided in this application. Figure 8 As shown, taking a television as an example, the television's core 706 can determine whether it is in game mode. If so, the core 706 can send a pop-up signal and software selection function, causing the display interface to display a pop-up window with operation options, allowing the user to choose whether to operate at a wide viewing angle. For example, the user can select the "yes" option in the pop-up window using a remote control.

[0108] If the user selects to enable the first display mode via a pop-up window, the mechanism 706 can send a signal to the display TCON IC704 to enable the first display mode. The TCON IC704 can then invoke the abnormal drive signal (i.e., the aforementioned first mapping relationship), and the panel can receive the TCON voltage signal to display specific grayscale levels. Specifically, the TCON IC704 can perform special voltage drive processing on all grayscale levels from 0-2% after recognizing the signal. This processing method could be achieved by pre-configuring a new grayscale adjustment voltage table (ACC table) for the TCON IC704, which corresponds to the aforementioned first mapping relationship. Unlike the normal table (i.e., the aforementioned second mapping relationship), the new ACC table allows the voltage to be set to 2% for all grayscale levels from 0-2%, enabling the TCON IC704 to directly invoke this table and complete the special voltage adjustment scheme. Alternatively, it can be improved using another set of Gamma voltages; for example, the voltage corresponding to any grayscale level in the aforementioned first mapping relationship can be greater than the voltage corresponding to that grayscale level in the second mapping relationship.

[0109] By actively converting all grayscale values ​​from 0-2% to 2%, taking a VA-type panel as an example, the liquid crystal partially deflects. This increases the component of birefringence in the frontal viewing direction and decreases the component in the transmission axis direction when viewed from the side. The color saturation decreases with the viewing angle ratio, thus mitigating color cast issues. The inventors' research revealed that black level light leakage in VA-type panels is generally maintained at 0.1 nits or less. When the grayscale is set at 2%-3%, the frontal light leakage is between 0.25-0.35 nits, a level of light leakage still lower than that of normal IPS panels, having minimal impact on user experience.

[0110] If the user selects not to enable the first display mode via a pop-up window, such as Figure 8 As shown, the mechanism 706 can transmit a signal indicating that the first display mode is not enabled to the TCON, so that the TCON can call the normal driving voltage (i.e., the aforementioned second mapping relationship). Alternatively, if the mechanism 706 determines that it is not in game mode, the mechanism 706 can transmit a signal indicating that it is not in game mode to the TCON, so that the TCON can call the normal driving voltage. The panel can receive the TCON voltage signal and display normally.

[0111] In some embodiments, the boot screen of the display device can be a built-in graphics card. This graphics card can be a 2% black grayscale graphics card.

[0112] In this embodiment, by displaying images based on the aforementioned first mapping relationship, compared to existing VA-type liquid crystal displays, this application improves the color shift of the VA panel under black levels and reduces the subjective color shift problem when viewed from the side in certain modes. This invention improves the side-view color shift problem of the VA panel under black levels by adding software functions, thereby enhancing the user experience.
