Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a control method for a display device, a display device, and a storage medium. Background Technology

[0002] Most mainstream displays on the market today are rectangular. In order to bring customers a different viewing experience, in addition to the conventional full-screen display, a technical solution for achieving rounded corner display on a rectangular screen has also emerged.

[0003] In related technologies, there are two main types of techniques for achieving rounded corner displays, each with its own drawbacks. One is the black matrix masking scheme, which uses a fixed black matrix to block light from the diagonal areas. However, this scheme can only output a fixed rounded corner image and cannot switch to full-screen display, resulting in a relatively limited display mode. The other is using algorithms to calculate the rounded corners. While this scheme supports free switching between full-screen and rounded corner display modes, it relies on directly extinguishing edge pixels to form rounded corners. However, due to the discrete arrangement of pixels, the rounded corners can only be formed by alternating bright and black pixels to create an arc-shaped jagged outline. Furthermore, because the inner part of the rounded corner is usually bright, there is a significant brightness jump between it and the outer black area, making the rounded corners clearly visible to the human eye as arc-shaped jagged bright lines, resulting in a poor visual experience. Summary of the Invention

[0004] The main objective of this application is to provide a control method for a display device, a display device, and a storage medium that can reduce the visual impact of jagged bright lines at the edges of the screen when switching to a first display mode, thereby optimizing the user's visual experience.

[0005] In a first aspect, this application provides a control method for a display device, the display device comprising: a display screen, the display screen comprising: a first display area and a plurality of second display areas located in corner areas of the display screen, the corners of the first display area being provided with transition areas, and the second display areas being disposed adjacent to the transition areas; the control method comprising: acquiring a display mode of the display device; if the display mode is a first display mode, controlling the first display area to display a preset image and controlling the second display areas to display a black image, and adjusting the driving differential pressure value of the second display areas to a first differential pressure value; The image data corresponding to the preset screen is acquired, and the brightness information of the transition area is determined based on the image data; based on the brightness information of the transition area, a target display area is determined from a plurality of second display areas; the target pressure difference value corresponding to the brightness information is determined, and the driving pressure difference value of the target display area is adjusted from the first pressure difference value to the target pressure difference value, so as to adjust the screen brightness corresponding to the target display area.

[0006] Secondly, this application provides a display device, the display device comprising: a display screen and a control module; the display screen comprising: a first display area and a plurality of second display areas located in corner areas of the display screen, the corners of the first display area being provided with transition areas, and the second display areas being adjacent to the transition areas; the control module being connected to the display screen, the control module being used to execute the control method as described above.

[0007] Thirdly, this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the control method described above.

[0008] This application provides a control method for a display device, a display device, and a storage medium. First, the display mode of the display device is acquired. If the display mode is a first display mode, a preset image is displayed in a first display area, and a black image is displayed in a second display area. The driving voltage difference value of the second display area is adjusted to the first voltage difference value. Second, image data corresponding to the preset image is acquired, and brightness information of the transition area is determined based on the image data. Next, based on the brightness information of the transition area, it is confirmed whether a transition area in the first display area is in a bright state, and a target display area is determined from multiple second display areas. Further, the control method is determined... The target voltage difference value corresponding to the brightness information is adjusted, and the driving voltage difference value of the target display area is adjusted from the first voltage difference value to the target voltage difference value. This causes a slight deflection of the liquid crystal molecules in the pixel unit within the target display area, allowing a small amount of backlight to penetrate the liquid crystal layer. This, in turn, increases the brightness of the screen corresponding to the target display area, thereby reducing the brightness difference between the target display area and the adjacent transition area that is in a high-brightness state. This further reduces the contrast difference between the two areas, weakening the visual impact of the originally prominent arc-shaped jagged bright lines at the edge of the screen (i.e., the transition area). This improves the unpleasant visual perception of the arc-shaped jagged bright lines and optimizes the user's visual experience. Attached Figure Description

Detailed Implementation

[0011] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0012] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0013] Based on this, embodiments of this application provide a control method for a display device, a display device, and a storage medium, which can reduce the visual impact of jagged bright lines at the edges of the screen when switching to a first display mode, thereby optimizing the user's visual experience.

[0014] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0015] Please refer to Figure 1 , Figure 2 In a first aspect, the present application provides a control method for a display device. The display device includes a display screen, which includes a first display area 100 and a plurality of second display areas 200 located at the corners of the display screen. A transition area 110 is provided at the corner of the first display area 100, and the second display areas 200 are adjacent to the transition areas 110.

[0016] For example, the display screen is square, and the first display area 100 has four corners. Each corner is provided with a transition area 110, which is arc-shaped and sawtooth-like. Figure 1 As shown, the corners of the first display area 100 are rounded. If the first display area 100 is controlled to display a preset image and the second display area 200 displays a black image, the display screen can present a rounded corner display effect. If both the first display area 100 and the second display area 200 are controlled to display the preset image, the display screen can present a right-angle display effect.

[0017] The control method for the display device includes steps S100-S500: S100: Obtain the display mode of the display device; It should be noted that the display modes include: a first display mode and a second display mode. The first display mode corresponds to a non-full-screen display mode, for example, a rounded corner display mode. The second display mode corresponds to a full-screen display mode, for example, a right-angle display mode.

[0018] S200: If the display mode is the first display mode, control the first display area 100 to display the preset screen and control the second display area 200 to display the black screen, and adjust the driving differential pressure value of the second display area 200 to the first differential pressure value Vop1; It should be noted that when the currently running display mode is identified as the first display mode, the image data corresponding to the preset screen is transmitted to the pixel unit array corresponding to the first display area 100 so that the first display area 100 displays the preset screen, and the image data corresponding to the black screen is transmitted to the pixel unit array corresponding to the second display area 200 so that the second display area 200 displays the black screen.

[0019] For example, the driving voltage difference value of the second display area 200 is the voltage difference between the source voltage Vsource and the electrode layer voltage Vcom corresponding to the pixel unit in the second display area 200. Adjusting the driving voltage difference value of the second display area 200 to a first voltage difference value Vop1 includes: determining a preset electrode layer voltage based on the first voltage difference value Vop1; controlling the source voltage Vsource corresponding to the pixel unit in the second display area 200 to remain unchanged, and adjusting the electrode layer voltage Vcom corresponding to the pixel unit in the second display area 200 to the preset electrode layer voltage, so as to adjust the driving voltage difference value of the second display area 200 to the first voltage difference value Vop1.

[0020] S300: Obtain image data corresponding to the preset screen and determine the brightness information of the transition area 110 based on the image data; It should be noted that when any transition area 110 in the first display area 100 is in a bright state, the second display area 200 adjacent to the transition area 110 is a black screen. The contrast difference between the two areas is large, so the transition area 110 appears as a distinct jagged arc bright line in the image of the first display area 100, with a strong visual sense of disjointness, which reduces the visual experience of the image.

[0021] It is understandable that the image data corresponding to the preset screen is obtained, and the brightness information of the transition area 110 is determined based on the image data, so as to provide data for subsequent judgment on whether there is a transition area 110 in a bright state.

[0022] S400: Determine the target display area from multiple second display areas 200 based on the brightness information of the transition area 110; For example, based on the brightness information of the transition area 110, it is confirmed whether there is a transition area 110 in the first display area 100 that is presented as a bright state. If there is a transition area 110 that is presented as a bright state, then the target display area is further determined from the plurality of second display areas 200 (that is, the second display area 200 that is adjacent to the transition area 110 that is presented as a bright state is determined as the target display area).

[0023] S500: Determine the target differential pressure value corresponding to the brightness information, and adjust the driving differential pressure value of the target display area from the first differential pressure value Vop1 to the target differential pressure value, so as to adjust the screen brightness corresponding to the target display area.

[0024] It should be noted that the target voltage difference is less than the first voltage difference Vop1. The driving voltage difference of the target display area is the voltage difference between the source voltage Vsource and the electrode layer voltage Vcom of the pixel unit in the target display area. If the display device is a liquid crystal display device, by adjusting the driving voltage difference of the target display area from the first voltage difference Vop1 to the target voltage difference, the liquid crystal molecules in the pixel unit in the target display area will be slightly deflected, and the backlight can penetrate the liquid crystal layer in a small amount. The brightness of the screen corresponding to the target display area is increased, so that the background color of the screen displayed in the target display area transitions smoothly from dark black to low brightness light gray (light black). This reduces the brightness difference between the target display area and the adjacent transition area 110, which is in a high-brightness state, and further reduces the contrast difference between the two areas. This weakens the visual impact of the originally prominent arc-shaped sawtooth bright lines in the edge of the screen (i.e., the transition area 110), thereby improving the unpleasant visual perception of the arc-shaped sawtooth bright lines and optimizing the user's visual experience.

[0025] It should be noted that if the preset screen displayed in the first display area 100 changes, the image data corresponding to the new preset screen is acquired accordingly, and the brightness information of the transition area 110 is determined based on the image data corresponding to the new preset screen. Then, a new target display area is determined from the multiple second display areas 200, and the driving voltage difference value of the new target display area is adjusted.

[0026] In some embodiments, after controlling the first display area 100 to display a preset image, the method further includes: adjusting the driving differential pressure value of the first display area 100 to a first differential pressure value Vop1.

[0027] For example, the driving voltage difference value of the first display area 100 is the voltage difference between the source voltage Vsource and the electrode layer voltage Vcom corresponding to the pixel unit in the first display area 100. Adjusting the driving voltage difference value of the first display area 100 to a first voltage difference value Vop1 includes: determining a preset electrode layer voltage based on the first voltage difference value Vop1; controlling the source voltage Vsource corresponding to the pixel unit in the first display area 100 to remain unchanged, and adjusting the electrode layer voltage Vcom corresponding to the pixel unit in the first display area 100 to the preset electrode layer voltage, so as to adjust the driving voltage difference value of the first display area 100 to the first voltage difference value Vop1.

[0028] Understandably, maintaining the driving voltage difference value of the first display area 100 at the first voltage difference value Vop1 during the operation of the first display mode ensures that the image clarity of the first display area 100 is not affected. Furthermore, adjusting the driving voltage difference value of the second display area 200 to the first voltage difference value Vop1 before further adjusting it based on the brightness information of the transition area 110 helps to keep the driving voltage difference values ​​of the second display area 200 and the first display area 100 consistent, thus ensuring that the base brightness of the second display area 200 and the first display area 100 is essentially the same.

[0029] In some embodiments, if the target display area includes a first target display area and a second target display area, determining the target differential pressure value corresponding to the brightness information and adjusting the driving differential pressure value of the target display area from the first differential pressure value Vop1 to the target differential pressure value to adjust the screen brightness corresponding to the target display area includes: determining the first target differential pressure value corresponding to the brightness information of the transition area 110 adjacent to the first target display area, and adjusting the driving differential pressure value of the first target display area from the first differential pressure value Vop1 to the first target differential pressure value to adjust the screen brightness corresponding to the first target display area; determining the second target differential pressure value corresponding to the brightness information of the transition area 110 adjacent to the second target display area, and adjusting the driving differential pressure value of the second target display area from the first differential pressure value Vop1 to the second target differential pressure value to adjust the screen brightness corresponding to the second target display area.

[0030] It is understandable that if the first display area 100 has two transition areas 110 that are in a bright state, then the second display area 200 adjacent to these two transition areas 110 is determined as the first target display area and the second target display area. The image brightness of the transition areas 110 at different positions may not be consistent, and the brightness and contrast formed with the corresponding adjacent target display areas may be different. By matching different target driving voltage difference values ​​to the first target display area and the second target display area according to the brightness information of the corresponding transition areas 110, the screen brightness of the first target display area and the second target display area can be adjusted more accurately.

[0031] It should be noted that the brighter the transition region 110, the smaller the driving voltage difference value of the corresponding target display area. This can significantly enhance the brightness of the displayed black screen, thereby reducing the brightness difference between the target display area and the adjacent transition region 110, decreasing the contrast difference between the two areas, and weakening the originally prominent jagged arc-shaped bright lines of the corresponding transition region 110, thus optimizing the user's visual experience. Therefore, if the brightness of the transition region 110 adjacent to the first target display area is higher than the brightness of the transition region 110 adjacent to the second target display area, the corresponding first target voltage difference value is less than the second target voltage difference value, allowing different transition regions 110 to achieve an appropriate jagged bright line weakening effect.

[0032] In some embodiments, if the target display area further includes a third target display area; after adjusting the driving differential pressure value of the second target display area from the first differential pressure value Vop1 to the second target differential pressure value, the method further includes: determining the third target differential pressure value corresponding to the brightness information of the transition area 110 adjacent to the third target display area, and adjusting the driving differential pressure value of the third target display area from the first differential pressure value Vop1 to the third target differential pressure value, so as to adjust the screen brightness corresponding to the third target display area.

[0033] In some embodiments, if the target display area further includes: a fourth target display area; after adjusting the driving differential pressure value of the third target display area from the first differential pressure value Vop1 to the third target differential pressure value, the method further includes: determining the fourth target differential pressure value corresponding to the brightness information of the transition area 110 adjacent to the fourth target display area, and adjusting the driving differential pressure value of the fourth target display area from the first differential pressure value Vop1 to the fourth target differential pressure value, so as to adjust the screen brightness corresponding to the fourth target display area.

[0034] In some embodiments, brightness information includes: the percentage of bright pixels, as referenced. Figure 3 Step S300 involves determining the brightness information of the transition region 110 based on the image data, including steps S310-S330: S310: Determine the grayscale value of each pixel in the first display area 100 based on the image data; For example, determining the grayscale value of each pixel in the first display area 100 based on image data includes: performing pixel-by-pixel traversal parsing on the image data to obtain the RGB grayscale value of each pixel in the first display area 100.

[0035] S320: Filter the grayscale values ​​of each pixel in the first display area 100 to obtain the grayscale values ​​of each pixel in the transition area 110. For example, filtering the grayscale values ​​corresponding to the first display area 100 to obtain the grayscale values ​​corresponding to the transition area 110 includes: obtaining the coordinate information of each transition area 110; filtering the RGB grayscale values ​​of each pixel in the first display area 100 based on the coordinate information of each transition area 110; extracting the grayscale values ​​of the pixels belonging to each transition area 110 and storing them to obtain the grayscale values ​​of each pixel in each transition area 110.

[0036] S330: Determine the proportion of bright pixels in the transition region 110 based on the grayscale values ​​of each pixel in the transition region 110.

[0037] For example, the grayscale value of each pixel can be converted into a luminance component, and then the proportion of bright pixels in the transition region 110 can be determined based on the luminance components of each pixel in the transition region 110. Furthermore, the higher the proportion of bright pixels, the more bright pixels there are in the transition region 110, the greater the brightness difference between it and the adjacent second display area 200, and the greater the contrast difference between the two areas, making the jagged bright lines of the transition region 110 appear more prominent in the image of the first display area 100.

[0038] In some embodiments, refer to Figure 4 In step S330, the proportion of bright pixels in the transition region 110 is determined based on the grayscale values ​​of each pixel in the transition region 110, including steps S331-S333: S331: Obtain the luminance component of each pixel in the transition region 110 based on the grayscale value of each pixel in the transition region 110. It should be noted that the brightness component of each pixel in the transition region 110 can be obtained through the brightness conversion formula and the RGB grayscale value of each pixel in the transition region 110.

[0039] S332: Based on the luminance components of each pixel in the transition region 110 and the preset luminance components, determine the bright pixels from the pixels in the transition region 110 and count the number of bright pixels. For example, determining a bright pixel from the pixels in the transition region 110 based on the luminance component of each pixel in the transition region 110 and a preset luminance component includes: comparing the luminance component of each pixel in the transition region 110 with the preset luminance component one by one, and determining the pixels in the transition region 110 whose luminance component is higher than the preset luminance component as bright pixels.

[0040] S333: The proportion of bright pixels in the transition region 110 is obtained based on the number of bright pixels.

[0041] For example, calculating the proportion of bright pixels in the transition region 110 based on the number of bright pixels includes: obtaining the total number of pixels in the transition region 110; and obtaining the proportion of bright pixels in the transition region 110 based on the ratio of the number of bright pixels to the total number of pixels.

[0042] In some embodiments, step S400 involves determining a target display area from among a plurality of second display areas 200 based on the brightness information of the transition area 110, including steps S410-S420: S410: Determine whether the transition region 110 is a target transition region based on the brightness information of the transition region 110. The target transition region is used to characterize the transition region 110 in a high-brightness state. For example, the brightness information includes: the proportion of bright pixels. Determining whether the transition region 110 is a target transition region based on the brightness information of the transition region 110 includes steps S411-S412: S411: If the proportion of bright pixels in the transition region 110 is greater than or equal to the preset proportion, then the transition region 110 is determined as the target transition region. Understandably, if transition area 110 is identified as the target transition area, it indicates that the number of bright pixels in transition area 110 is too high, the corresponding image of the target transition area is too bright, and the brightness difference and contrast difference between the target transition area and the adjacent second display area 200 are relatively large, making the jagged outline of the target transition area clearly recognizable by the human eye, resulting in a poor image quality. It is necessary to further adjust the driving voltage difference value of the second display area 200 adjacent to the transition area 110 to improve the poor visual perception of the arc-shaped jagged bright lines displayed in the target transition area.

[0043] For example, the preset percentage is 70%, and the preset percentage can be adaptively adjusted within the range of 50% to 95%. In this application, the preset percentage is not limited in too much.

[0044] S412: If the proportion of bright pixels in the transition area 110 is less than the preset proportion, the driving voltage difference value of the second display area 200 adjacent to the transition area 110 will be maintained at the first voltage difference value Vop1.

[0045] Understandably, if the proportion of bright pixels in the transition area 110 is less than the preset proportion, it indicates that the number of bright pixels in the transition area 110 is relatively small, the overall image of the transition area 110 is relatively dark, the brightness difference and contrast difference between it and the adjacent second display area 200 are small, the visual recognition of the arc-shaped jagged outline of the transition area 110 by the human eye is low, and the image quality is good. Therefore, there is no need to further set the second display area 200, which is not adjacent to the target transition area, as the target display area. It is sufficient to maintain the original driving voltage difference value, which can effectively reduce the computational burden of the driving chip used to adjust the driving voltage difference value, thereby improving the service life of the display device.

[0046] S420: The second display area 200 adjacent to the target transition area is determined as the target display area.

[0047] It should be noted that the second display area 200 adjacent to the target transition area is defined as the target display area. Subsequently, it is only necessary to adjust the driving voltage difference value of the target display area to moderately increase the brightness of the screen corresponding to the target display area, reduce the brightness difference between the target transition area and the target display area, reduce the human eye's ability to distinguish the arc-shaped jagged bright lines presented in the target transition area, and make the objectively existing arc-shaped jagged bright lines appear to fade in visual perception.

[0048] In some embodiments, determining the target pressure difference value corresponding to the brightness information in step S500 includes steps S510-S520: S510: Obtain a preset mapping table, which is used to characterize the mapping relationship between brightness information and driving pressure difference value; For example, a large number of display screens are lit up in the early stage, and historical brightness data and historical pressure difference data are collected during the experiment. Then, a preset mapping table is constructed by fitting the historical brightness data and historical pressure difference data. In the preset mapping table, a corresponding mapping relationship is established between the brightness information of the transition area 110 (e.g., the proportion of high-brightness pixels) and the driving pressure difference value of each level.

[0049] S520: Based on a preset mapping table, determine the target pressure difference value according to the brightness information.

[0050] Understandably, the driving voltage difference value matching the brightness information is searched in a preset mapping table, and the found driving voltage difference value is determined as the target voltage difference value. Then, by gradually adjusting the driving voltage difference value of the target display area from the first voltage difference value Vop1 to the target voltage difference value, the light transmittance of the liquid crystal layer in the target display area is gradually changed, thereby gradually increasing the brightness of the corresponding screen in the target display area. This causes the background color of the screen displayed in the target display area to smoothly transition from deep black to low-brightness light gray (light black). By controlling the brightness change of the corresponding screen in the target display area, the brightness difference between the target display area and the adjacent transition area 110 can be reduced, weakening the visual contrast between the two areas. This completes the contrast calibration and edge grayscale compensation to adapt to the current screen condition of the transition area 110, thereby reducing the visual impact of the originally prominent arc-shaped sawtooth bright lines in the edge of the screen (i.e., the transition area 110), and improving the unpleasant visual perception of the arc-shaped sawtooth bright lines.

[0051] In some embodiments, the driving voltage difference value of the target display area is the voltage difference between the source voltage Vsource and the electrode layer voltage Vcom corresponding to the pixel unit in the target display area. Step S500, adjusting the driving voltage difference value of the target display area from the first voltage difference value Vop1 to the target voltage difference value, includes: determining the target electrode layer voltage based on the target voltage difference value; keeping the source voltage Vsource corresponding to the pixel unit in the target display area unchanged, and adjusting the electrode layer voltage Vcom corresponding to the pixel unit in the target display area from the preset electrode layer voltage to the target electrode layer voltage, so as to adjust the driving voltage difference value of the target display area from the first voltage difference value Vop1 to the target voltage difference value.

[0052] It should be noted that the voltage of the electrode layer corresponding to the first differential voltage Vop1 driving voltage of the target display area is the preset electrode layer voltage.

[0053] For example, controlling the source voltage Vsource corresponding to the pixel unit in the target display area to remain unchanged, and adjusting the electrode layer voltage Vcom corresponding to the pixel unit in the target display area from the preset electrode layer voltage to the target electrode layer voltage, includes: controlling the source voltage Vsource corresponding to the pixel unit in the target display area to remain unchanged, and adjusting the electrode layer voltage Vcom corresponding to the pixel unit in the target display area from the preset electrode layer voltage to the target electrode layer voltage based on a preset segmented adjustment mode within a single frame image period.

[0054] Furthermore, within a single frame image period, the electrode layer voltage Vcom corresponding to the pixel unit in the target display area is adjusted from the preset electrode layer voltage to the target electrode layer voltage based on a preset segmented adjustment mode. This includes: dividing the single frame image period into multiple consecutive time intervals, each time interval corresponding to an electrode layer voltage Vcom; sequentially switching the electrode layer voltage Vcom corresponding to each time interval along the time sequence to adjust the electrode layer voltage Vcom corresponding to the pixel unit in the target display area from the preset electrode layer voltage to the target electrode layer voltage, thereby adjusting the driving voltage difference value of the target display area from the first voltage difference value Vop1 to the target voltage difference value.

[0055] For example, refer to Figure 5 The single-frame image period is divided into six consecutive time intervals. In the first time interval, the electrode layer voltage Vcom corresponds to the first voltage (i.e., the preset electrode layer voltage), and the driving voltage difference value of the first time interval corresponds to the first voltage difference value Vop1. In the second time interval, the electrode layer voltage Vcom corresponds to the second voltage, and the driving voltage difference value of the second time interval corresponds to the second voltage difference value Vop2. In the third time interval, the electrode layer voltage Vcom corresponds to the third voltage, and the driving voltage difference value of the third time interval corresponds to the third voltage difference value Vop3. In the fourth time interval, the electrode layer voltage Vcom corresponds to the fourth voltage, and the driving voltage difference value of the fourth time interval corresponds to the fourth voltage difference value Vop4. In the fifth time interval, the electrode layer voltage Vcom corresponds to the fifth voltage, and the driving voltage difference value of the fifth time interval corresponds to the fifth voltage difference value Vop5. In the sixth time interval, the electrode layer voltage Vcom corresponds to the sixth voltage (i.e., the target electrode layer voltage), and the driving voltage difference value of the sixth time interval corresponds to the sixth voltage difference value Vop6 (i.e., the target voltage difference value).

[0056] It is understandable that by switching the electrode layer voltage Vcom corresponding to the pixel unit in the target display area multiple times within a single frame image cycle, the driving voltage difference value of the target display area is changed multiple times, so that the driving voltage difference value of the target display area gradually approaches the target voltage difference value. Each change in the driving voltage difference value corresponds to a change in the brightness of the screen corresponding to the target display area. With the multiple switching of the driving voltage difference value, the brightness difference between the target display area and the adjacent transition area 110, which is in a high-brightness state, is gradually reduced, and the contrast difference between the two areas is weakened. At the same time, by utilizing the persistence of vision effect of the human eye, the jagged edges caused by the discrete arrangement characteristics of pixels are blurred in the time dimension, so that the screen displayed by the target display area and the first display area 100 transitions naturally.

[0057] In some embodiments, the display mode further includes: a second display mode; if the display mode is the second display mode, both the first display area 100 and the second display area 200 are controlled to display a preset image, and the driving pressure difference value of the first display area 100 and the second display area 200 is adjusted to a first pressure difference value Vop1, such as Figure 6 As shown.

[0058] It should be noted that the second display mode corresponds to the full-screen display mode, for example, the second display mode is the right-angle display mode.

[0059] Understandably, if the display mode is switched to the second display mode (i.e., full-screen display), the second display area 200 no longer acts as a black screen area, and can work in conjunction with the first display area 100 to output the preset screen content. Furthermore, by uniformly adjusting the driving voltage difference values ​​of the first display area 100 and the second display area 200 to the first voltage difference value Vop1, the light transmission characteristics of the liquid crystal layer in the first display area 100 and the second display area 200 are kept consistent. This reduces the differences in brightness and grayscale among the display areas, making the displayed image more complete and continuous, allowing for natural transitions between display areas and reducing visual disjointedness.

[0060] Secondly, embodiments of this application provide a display device, which includes a display screen and a control module; the display screen includes a first display area 100 and a plurality of second display areas 200 located in the corner areas of the display screen, the corner of the first display area 100 is provided with a transition area 110, and the second display areas 200 are adjacent to the transition areas 110; the control module is connected to the display screen and is used to execute the control method as described in any of the above embodiments.

[0061] For example, the display screen is square, and the first display area 100 has four corners. Each corner is provided with a transition area 110, which is arc-shaped and sawtooth-shaped, so that the corners of the first display area 100 are rounded.

[0062] It should be noted that the display screen is divided into a first display area 100 and multiple second display areas 200 located at the corners of the display screen. By adjusting the images displayed in the first display area 100 and the second display areas 200, multiple display modes can be switched on the display screen. Specifically: if the control module controls the first display area 100 to display a preset image and the second display area 200 to display a black image, the display screen can present a rounded corner display effect. If the rounded corner edge of the first display area 100 (i.e., the transition area 110) presents as an arc-shaped sawtooth bright line, it can also be controlled by... The module adjusts the driving voltage difference value of the second display area 200 adjacent to the transition area 110 to the target driving voltage difference value, so as to improve the brightness of the screen corresponding to the second display area 200, reduce the brightness difference between the second display area 200 and the adjacent transition area 110, weaken the contrast between the two areas, and reduce the human eye's perception of the originally prominent jagged arc bright line of the transition area 110, so as to optimize the user's visual experience; if the control module controls both the first display area 100 and the second display area 200 to display the preset image, the display screen can present a right-angle display effect.

[0063] Thirdly, embodiments of this application provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the control method as described in any of the above embodiments.

[0064] For details on the implementation of each of the above operations, please refer to the previous examples, which will not be repeated here.

[0065] According to the control method, display device, and storage medium of the display device provided in the embodiments of this application, firstly, the display mode of the display device is obtained. If the display mode is a first display mode, the first display area 100 is controlled to display a preset image and the second display area 200 is controlled to display a black image, and the driving voltage difference value of the second display area 200 is adjusted to the first voltage difference value Vop1. Secondly, the image data corresponding to the preset image is obtained, and the brightness information of the transition area 110 is determined according to the image data. Then, according to the brightness information of the transition area 110, it is confirmed whether there is a transition area 110 in the first display area 100 that is in a high-brightness state, and a target is determined from multiple second display areas 200. The display area is further defined by determining the target differential pressure value corresponding to the brightness information and adjusting the driving differential pressure value of the target display area from the first differential pressure value Vop1 to the target differential pressure value. This causes the liquid crystal molecules in the pixel unit of the target display area to undergo a slight deflection, allowing a small amount of backlight to penetrate the liquid crystal layer. This, in turn, increases the brightness of the screen corresponding to the target display area, thereby reducing the brightness difference between the target display area and the adjacent transition area 110, which is in a high-brightness state. This further reduces the contrast difference between the two areas, thereby weakening the visual impact of the originally prominent arc-shaped sawtooth bright lines at the edge of the screen (i.e., the transition area 110), thus improving the unpleasant visual experience of the arc-shaped sawtooth bright lines and optimizing the user's visual experience.
