[0066] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0068] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.

[0069] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0070] The display compensation method for display modules provided in this application can compensate for the unevenness of display caused by the textured outer surface of the display module, thereby improving the display uniformity of the display module and enhancing the display effect of the display module.

[0071] In one embodiment, such as Figure 1 As shown, a display compensation method for a display module is provided, wherein the outer surface of the display area of ​​the display module has a texture. The method includes steps S100 and S110.

[0072] Step S100: Obtain the appearance image information of the outer surface of the display area when the display module is not lit.

[0073] The display module's display area features a textured outer surface. This outer surface can be understood as the light-emitting side. The tactile feel of the display module's outer surface can be leather, wood grain, fabric, glass, or plastic, among others. The surface can be diffuse matte or reflective glossy, allowing it to blend seamlessly with its surroundings when not illuminated. For example, it can appear as a unified black, brown, or gray color. When unlit, it's impossible to detect as a display module with the naked eye, enhancing the harmony, sophistication, design, and aesthetics of the entire environment. This contributes to a smart living experience. For those seeking high-quality displays, it also restores the original appearance of the environment by using technology to conceal the display. This allows the display module to maintain its display quality during use and, when not in use, restores the original appearance of the environment (car, furniture, etc.). This creates a seamless environment, significantly improving its aesthetics and overall unity.

[0074] For example, a display module includes a display module, which includes a display area. The display area includes a textured outer surface, wherein the display module is used for display, and the texture is a feature inherent to the display module itself. In another example, a display module includes a display module and a membrane material. The membrane material is located on the light-emitting side of the display area of ​​the display module. The membrane material is transparent and textured, and the texture is a feature inherent to the membrane material itself. For example, an environmentally integrated surface membrane material can be used to replace the original glass cover. The membrane material can be made of wood, silicone, leather, plastic, etc. The membrane material has a certain light transmittance, for example, a transmittance range of 20% to 55%. The light transmittance of the membrane material is related to its material and is not limited further here.

[0075] When the display module is not lit, the appearance image information of the outer surface of the display area of ​​the display module can be obtained through devices such as charge coupled device (CCD) cameras and optical probes.

[0076] When acquiring the appearance image information of the outer surface of the display area of ​​the display module, it is necessary to ensure that the illuminance of the environment in which the display module is located is at a preset brightness. That is, the appearance image information is acquired under the preset brightness of the environment in which the display module is located, thereby ensuring that the appearance image information of the outer surface can be clearly captured. This appearance image information can clearly present information such as the depth and position of the surface texture. In some embodiments, the preset brightness range is 100lx to 300lx, for example, it can be 100lx, 150lx, 200lx, 250lx or 300lx, or any suitable value between 100lx and 300lx, which is not limited here.

[0077] Step S110: Based on the appearance image information, determine the first compensation data of the display area of ​​the display module, wherein the first compensation data is used to perform display compensation on the display module.

[0078] After capturing the exterior image information, information such as the depth and location of the surface texture can be obtained from it. When the display module is lit, the surface texture interferes with the display effect; darker areas of the texture reduce the display brightness. Therefore, after collecting the distribution of the surface texture, pre-compensation settings can be made on the display module based on this distribution. This involves using first compensation data to compensate the display module. For example, for areas with deeper textures on the exterior surface, the driving electrical signal at those areas is relatively increased to improve the brightness of those areas, thus compensating for the reduced brightness caused by the deeper textures.

[0079] In this embodiment, the method is applied to a display module whose outer surface of the display area has a texture. The method first acquires the appearance image information of the outer surface of the display area when the display module is not lit, thus facilitating subsequent analysis of the texture distribution of the outer surface of the display module based on the appearance image information. Based on the appearance image information, first compensation data for the display area of ​​the display module is determined. Since the first compensation data can be used to perform display compensation on the display module, it can offset the impact of the texture of the outer surface of the display module on the display effect, thereby improving the uniformity of the displayed image and ultimately improving the display effect.

[0080] In one embodiment, such as Figure 2 As shown, step S110 involves determining the first compensation data for the display area of ​​the display module based on the appearance image information. This includes steps S200-S210.

[0081] Step S200: Obtain the inverted color image information of the appearance image information by performing color inversion processing on the appearance image information.

[0082] The maximum gray value of the appearance image information is obtained by adding the gray values ​​of each sub-pixel of the inverted color image information to the gray values ​​of each sub-pixel of the appearance image information.

[0083] After obtaining the appearance image information, the image information is converted to a grayscale image, where the display data of each sub-pixel is represented by a grayscale value. Then, the appearance image information is inverted to obtain the inverted color image information. The grayscale value of each sub-pixel is less than the maximum grayscale value.

[0084] For example, taking a maximum grayscale value of 255 as an example, the inversion process is represented by the following formula:

[0085] I mage =255-I mage

[0086] Among them, I mage 'I' is the grayscale value of a sub-pixel of the inverted color image information. mage This represents the grayscale value of the corresponding sub-pixel of the appearance image information, with 255 being the maximum grayscale value. For example, the grayscale value I of a sub-pixel of the appearance image information. mage =50, the grayscale value I of the sub-pixel corresponding to the inverted color image information. mage =205.

[0087] Another example, taking a maximum grayscale value of 0 as an example, is the inversion process represented by the following formula:

[0088] I mage '=0-I mage

[0089] Among them, I mage 'I' is the grayscale value of a sub-pixel of the inverted color image information. mage This represents the grayscale value of the corresponding sub-pixel of the appearance image information, with 0 being the maximum grayscale value. For example, the grayscale value I of a sub-pixel of the appearance image information. mage =32, the grayscale value I of the sub-pixel corresponding to the inverted color image information. mage = -32.

[0090] In practical applications, the maximum grayscale value can be preset and set according to the specific scenario; no limitation is made here.

[0091] Step S210: Use the inverted color image information as the first compensation data.

[0092] The appearance image information and its corresponding inverted color image information are complementary in grayscale value, and their sum equals the maximum grayscale value. Therefore, when the display module displays the inverted color image information, it perfectly cancels out the texture on the outer surface, achieving a white image and preventing the display module from being affected by the texture when displaying subsequent images. The displayed inverted color image information is then recorded as the first compensation data. Alternatively, without activating the display module, a lookup table can be used to directly obtain the driving electrical signal corresponding to the grayscale value of each sub-pixel when the display module displays the inverted color image information, based on the gamma curve built into the display module. This signal is then recorded as the first compensation data.

[0093] In this embodiment, by inverting the color of the appearance image information, first compensation data is obtained, which can offset the texture on the outer surface, so that the display module is not affected by the texture when displaying the image.

[0094] In one embodiment, such as Figure 3 As shown, step S200 involves inverting the appearance image information to obtain the inverted color image information. This includes steps S300-S320.

[0095] Step S300: Based on the appearance image information, determine the grayscale value of each sub-pixel in the display area at the preset grayscale level.

[0096] After obtaining the appearance image information, preprocessing such as filtering and noise reduction can be performed. Then, the appearance image information is converted into a grayscale image, where the display data of each sub-pixel is represented by a grayscale value. The preset grayscale level can be 256 grayscale levels or other grayscale levels.

[0097] Step S310: Based on the maximum gray value under the gray level, the gray values ​​corresponding to each sub-pixel of the appearance image information are inverted to determine the inverted gray value corresponding to each sub-pixel to obtain the inverted color image information.

[0098] In this context, the grayscale values ​​of each sub-pixel in the inverted color image information are the inverted grayscale values ​​of the corresponding sub-pixels in the appearance image information. By inverting the grayscale value of each sub-pixel in the appearance image information, the inverted grayscale value of each sub-pixel can be obtained, and the grayscale value of the sub-pixel corresponding to the inverted color image information is thus the inverted grayscale value of the sub-pixel corresponding to the appearance image information. Specifically, this can be achieved by adjusting the chroma and brightness of the appearance image information to invert the grayscale values ​​of the sub-pixels.

[0099] For example, the grayscale value of each sub-pixel of the inverted color image information, which is the inverted grayscale value of the corresponding sub-pixel of the appearance image information, is determined by the following formula:

[0100] I mage =255-I mage

[0101] Among them, I mage 'I' is the grayscale value of a sub-pixel of the inverted color image information (the inverted grayscale value of the corresponding sub-pixel of the appearance image information). mage This represents the grayscale value of the corresponding sub-pixel of the appearance image information, with 255 being the maximum grayscale value.

[0102] In one embodiment, please refer to... Figure 3The display compensation method for the display module may further include step S320, correcting the grayscale value of each sub-pixel in the inverted color image information so that the grayscale value of each sub-pixel in the inverted color image information is kept within a preset range defined by the grayscale level.

[0103] After obtaining the inverted color image information, it is also necessary to perform correction and verification on the grayscale values ​​of each sub-pixel of the inverted color image information. This is because the adjustment of brightness and chroma may result in overcompensation, so it is necessary to correct it so that the grayscale values ​​of each sub-pixel in the inverted color image information are kept within a preset range. The preset range is a predefined normal range of grayscale values.

[0104] After obtaining the grayscale values ​​of each sub-pixel of the inverted color image information, each sub-pixel's grayscale value can be represented as a data code with a physical address. This code is then programmed into the driver chip of the display module. When the display module displays an image, sub-pixels at different positions use the programmed electrical signals for display compensation, thus ensuring that the displayed image is not affected by texture. The correspondence between each sub-pixel and its corresponding surface compensation electrical signal can be recorded and stored.

[0105] In this embodiment, a method for inverting the color of appearance image information is provided, which can obtain the inverted color image information of appearance image information, thereby facilitating the compensation of uneven display caused by the surface texture of the exterior surface and ensuring that the displayed image is not affected by the texture.

[0106] In one embodiment, such as Figure 4 As shown, the display compensation method for the display module may further include the following steps S400 and S410.

[0107] Step S400: Determine the sub-compensation data corresponding to each sub-pixel in the display area based on the first compensation data.

[0108] Sub-compensation data refers to the compensation data corresponding to sub-pixels in the display area. For example, compensation data can be understood as voltage values. For instance, if the sub-compensation data includes surface compensation electrical signals corresponding to sub-pixels, then the first compensation data can be used as the surface compensation electrical signals corresponding to each sub-pixel in the display area. For example, surface compensation electrical signals can be understood as voltage signals.

[0109] Step S410: The sub-compensation data corresponding to each sub-pixel is used to compensate the driving electrical signal of each sub-pixel in the display area, so as to drive the display area to display through the compensated driving electrical signal.

[0110] In this system, after determining the sub-compensation data corresponding to each sub-pixel, targeted and differentiated compensation can be performed on each sub-pixel when the display module is lit. Specifically, for areas with deep texture, the driving electrical signal can be increased accordingly, and for areas with shallow texture, the driving electrical signal can be decreased accordingly, so that areas with deep texture and areas with shallow texture present the same display effect, eliminating the influence of the outer surface texture on the display effect of the display module.

[0111] In this embodiment, the method is applied to a display module whose outer surface of the display area has a texture. First, with the display module off-light, the method acquires an image of the outer surface of the display area, facilitating subsequent analysis of the texture distribution of the outer surface. Based on the image, first compensation data for the display area is determined, and sub-compensation data corresponding to each sub-pixel in the display area is determined based on this first compensation data. This allows for the determination of the compensation adjustment electrical signal based on the texture distribution of the outer surface, facilitating subsequent texture compensation. By using the sub-compensation data corresponding to each sub-pixel to compensate the driving electrical signals of each sub-pixel in the display module, the influence of the texture of the outer surface on the display effect can be offset, improving the uniformity of the displayed image and enhancing the overall display effect.

[0112] In one embodiment, please refer to... Figure 4 As shown, after step S410, the compensation method of the display module further includes steps S420-S430, after the sub-compensation data corresponding to each sub-pixel is used to compensate the driving electrical signal of each sub-pixel in the display area.

[0113] Step S420: Based on the compensated driving electrical signal, obtain the display parameters when the display module displays the image.

[0114] The process can take place in a dark room, where the display module is illuminated. The dark room can be an environment with an illuminance of 200 lx, which helps to highlight the display parameters of the module and reduces interference from ambient brightness. During illumination, sub-pixels of the three colors (R, G, and B) can be illuminated separately at different gray levels, such as 0-255 gray levels. Data on the display parameters of each color sub-pixel at each gray level is collected to facilitate subsequent gamma adjustment of the display module. It is understood that the current display module has already compensated its driving electrical signals based on the first compensation data using the method described in the above embodiment. Therefore, the display module has pre-set surface compensation electrical signals for each sub-pixel, and subsequent gamma adjustments are made based on these surface compensation electrical signals. For example, if the display module needs to display a red image, it needs to receive the driving electrical signal for the red image (denoted as the red driving electrical signal). When displaying a red image, the actual driving electrical signal for each sub-pixel is the corresponding red driving electrical signal plus the surface compensation electrical signal.

[0115] Step S430: If the display parameters do not match the preset target display parameters, determine the drive compensation signal based on the current drive electrical signal of the display module, the display parameters, and the target display parameters.

[0116] The current driving signal is the compensated driving signal. The driving compensation signal is used to adjust the current driving signal of the display module so that the display parameters of the display module match the target display parameters.

[0117] The mismatch between the display parameters and the preset target display parameters can be understood as the display parameters such as brightness when the display module displays the image not being within the range of the corresponding target display parameters. Therefore, it is necessary to adjust the drive electrical signal until the display parameters of the display module match the target display parameters. The total adjustment amount in this process is the drive compensation signal.

[0118] In this embodiment, the display data of the display module when displaying an image is first obtained, i.e., the actual display data of the display module before gamma adjustment. This display data is then used as reference data for subsequent gamma adjustment of the display module. Next, it is determined whether the display data of the display module matches the target display data. If the display data does not match the target display data, it means that the display module needs gamma adjustment to achieve a better display effect. Therefore, a drive compensation signal is determined based on the current drive electrical signal of the display module, the display parameters, and the target display parameters. Adjusting the current drive electrical signal of the display module using the drive compensation signal ensures that the display parameters of the display module match the target display parameters, thus completing the gamma adjustment of the display module.

[0119] In one embodiment, step S420 involves determining a drive compensation signal based on the current drive electrical signal of the display module, the display parameters, and the target display parameters when the display parameters do not match the preset target display parameters. Specifically, this includes:

[0120] The first color driving compensation signal is determined based on the display parameters, the first color driving electrical signal, and the target display parameters. The second color driving compensation signal is determined based on the display parameters, the second color driving electrical signal, and the target display parameters. The third color driving compensation signal is determined based on the display parameters, the third color driving electrical signal, and the target display parameters.

[0121] The current driving electrical signals of the display module include a first color driving electrical signal, a second color driving electrical signal, and a third color driving electrical signal. The driving electrical signal of the same color is used to provide to the corresponding color pixel to drive the corresponding color sub-pixel to emit light.

[0122] The display module includes multiple sub-pixels of different colors. By adjusting the driving electrical signals provided to the sub-pixels of different colors, the display parameters of the sub-pixels of different colors can be adjusted independently, ensuring that the display parameters of each sub-pixel of different colors can match the corresponding target display parameters.

[0123] The driving compensation signal includes a first color driving compensation electrical signal, a second color driving compensation electrical signal, and a third color driving compensation electrical signal. The first color driving compensation electrical signal is used to adjust the first color driving electrical signal, the second color driving compensation electrical signal is used to adjust the second color driving electrical signal, and the third color driving compensation electrical signal is used to adjust the third color driving electrical signal.

[0124] For example, at the current grayscale, the first color sub-pixel is illuminated using an initial first color driving electrical signal, the second color sub-pixel is illuminated using an initial second color driving electrical signal, and the third color sub-pixel is illuminated using an initial third color driving electrical signal. Then, the display data of the current display module is acquired, and the first, second, and third color driving electrical signals are adjusted respectively. The display data of the current display module is acquired in real time until the display data of the current display module matches the target display data. The change between the first color driving electrical signal when the display data of the current display module matches the target display data and the initial first color driving electrical signal is used as the first color driving compensation electrical signal. The change between the second color driving electrical signal when the display data of the current display module matches the target display data and the initial second color driving electrical signal is used as the second color driving compensation electrical signal. The change between the third color driving electrical signal when the display data of the current display module matches the target display data and the initial third color driving electrical signal is used as the third color driving compensation electrical signal.

[0125] In order to ensure that the overall display data of the display module reaches the corresponding target display data, sub-pixels of different colors may have different driving electrical signals at the same grayscale; sub-pixels of the same color may have the same driving electrical signal at the same grayscale; however, sub-pixels of the same color may have different driving electrical signals at different grayscales; and sub-pixels of different colors may have the same driving electrical signal at different grayscales. Therefore, it is necessary to independently adjust the driving electrical signals of sub-pixels of each color at each grayscale.

[0126] In this embodiment, the color calibration of the display module is completed by independently adjusting the sub-pixels of the three colors respectively.

[0127] In one embodiment, such as Figure 5 As shown, the drive compensation signal is determined based on the current drive electrical signal of the display module, the display parameters, and the target display parameters, including steps S500-S530.

[0128] Step S500: Obtain the display parameters of the sub-pixels of the target color when the display module displays the image under the grayscale binding points to be debugged.

[0129] The target color is one of the first color, the second color, and the third color.

[0130] In the gamma adjustment process, multiple grayscale binding points are usually obtained, and then gamma correction is performed on multiple grayscale binding points. After the gamma correction of multiple grayscale binding points is completed, the voltage corresponding to other grayscale levels is calculated by linear interpolation, thus completing the gamma adjustment.

[0131] For example, if the display module includes 256 gray levels, a gray level binding point can be selected every 15 gray levels, resulting in 17 gray level binding points. After performing gamma adjustment on the gray level binding points to obtain the voltages corresponding to these 17 gray level binding points, linear interpolation is performed on every two adjacent gray level binding points. This process is repeated multiple times to obtain the voltages corresponding to the remaining 239 gray levels. Thus, gamma adjustment of each gray level of the display module can be quickly completed by performing gamma adjustment on only a small number of gray level binding points, making gamma adjustment faster and simpler.

[0132] Step S510: Determine the target display parameters corresponding to the grayscale binding points based on the grayscale binding points and the preset gamma curve.

[0133] The gamma curve represents the relationship between grayscale and output brightness. In this embodiment, the preset gamma curve can be a standard gamma curve, specifically a curve showing the relationship between grayscale and brightness when the gamma value is 2.2. At this value, the grayscale images appear most natural to the human eye. It should be noted that, generally speaking, the relationship between the brightness perceived by the human eye and the actual display brightness of the display panel is not linear. In low-brightness environments, the human eye is more sensitive to changes in brightness, while in high-brightness environments, the opposite is true. Due to the non-linear perception of brightness by the human eye, if we need to obtain a uniformly varying brightness perception, the brightness displayed by the display panel needs to vary non-uniformly to adapt to the gamma characteristics of the human eye. The non-linear parameter between the brightness and grayscale level of the display panel can be called the gamma value, and the brightness and grayscale curve plotted based on the gamma value is called the gamma curve. The gamma value characterizes the non-linear relationship between brightness and grayscale. Extensive experiments have shown that a gamma curve with a gamma value of 2.2 presents the best display effect.

[0134] By substituting the grayscale binding points into the preset gamma curve, the target brightness data corresponding to each grayscale binding point can be obtained directly.

[0135] Step S520: Adjust the initial driving electrical signal of the target color sub-pixel at the grayscale binding point to be debugged until the display parameters of the target color sub-pixel in response to the adjusted driving electrical signal match the target display parameters.

[0136] The display parameters of the display module are measured. By comparing the display parameters of the display module measured at the bound grayscale with the target display parameters, it can be determined whether the display parameters match the target display parameters.

[0137] Step S530: Based on the difference between the adjusted driving electrical signal and the initial driving electrical signal of the target color sub-pixel at the grayscale binding point to be adjusted, determine the driving compensation signal corresponding to the grayscale binding point to be adjusted.

[0138] The adjusted driving signal, which is the driving signal when the display parameters match the target display parameters, is compared with the initial driving signal before debugging. The difference between them is the total adjustment amount, which is the driving compensation signal corresponding to the grayscale binding point of the target color sub-pixel in the grayscale binding point to be debugged.

[0139] After completing the gamma adjustment, the correspondence between grayscale binding points and the compensation driving electrical signals of the corresponding target color sub-pixels can be recorded and stored.

[0140] In this embodiment, by comparing the display parameters under grayscale binding points when the display module displays an image with the target display parameters, and then adjusting the driving electrical signals of the sub-pixels of different colors of the display module at the grayscale binding points to be adjusted, the driving compensation signal corresponding to the sub-pixels of the target color at the grayscale binding points to be adjusted is determined, thus completing the gamma adjustment action.

[0141] It should be understood that, although Figures 1-5 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figures 1-5 At least some of the steps in the process may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the steps or stages in other steps.

[0142] Based on the same inventive concept, this application also provides a driving method for a display module. This driving method can be applied to a driving device for the display module, such as a driver chip, and can drive the display module to display, improving the display uniformity of the display module and thus enhancing the display effect. The outer surface of the display area of ​​the display module has a texture; such as... Figure 6 As shown, the driving method of the display module includes the following steps S600 and S610.

[0143] S600: Obtain first compensation data, wherein the first compensation data is determined by obtaining the appearance image information of the outer surface of the display area when the display module is not lit, and based on the appearance image information. The first compensation data is used to perform display compensation on the display module. For details, please refer to the aforementioned related introduction, which will not be repeated here.

[0144] S610: Drives the display module to display based on the first compensation data.

[0145] In this embodiment, the method is applied to a display module whose outer surface of the display area has a texture. The method obtains first compensation data and drives the display module to display based on the first compensation data. Since the first compensation data is obtained by obtaining the appearance image information of the outer surface of the display area when the display module is not lit, and determined based on the appearance image information, and since the appearance image information includes the texture distribution of the outer surface of the display module, the first compensation data of the display area of ​​the display module can be used to perform display compensation on the display module. Therefore, driving the display module to display based on the first compensation data can offset the influence of the texture of the outer surface of the display module on the display effect, improve the uniformity of the display screen of the display module, and thus improve the display effect.

[0146] In one embodiment, the first compensation data is the inverted image information obtained by inverting the appearance image information.

[0147] In one embodiment, the appearance image information is obtained when the display module is at a preset brightness.

[0148] In one embodiment, the preset brightness range is 100xl-300xl.

[0149] In one embodiment, the display module includes a display module, the display module includes a display area, and the display area includes a textured exterior surface.

[0150] In one embodiment, the display panel includes a display module and a film material located on the light-emitting side of the display area of ​​the display module. The film material is transparent and has a texture.

[0151] In one embodiment, the inverted color image information is obtained by determining the grayscale value of each sub-pixel in the display area at a preset grayscale level based on the appearance image information, and inverting the grayscale value corresponding to each sub-pixel of the appearance image information according to the maximum grayscale value at the grayscale level, and by determining the inverted grayscale value corresponding to each sub-pixel.

[0152] In one embodiment, the first compensation data is used to determine the sub-compensation data corresponding to each sub-pixel in the display area, and the driving electrical signal of each sub-pixel in the display area is compensated using the sub-compensation data corresponding to each sub-pixel. Step 610, driving the display module based on the first compensation data, includes: driving the display area using the compensated driving electrical signal.

[0153] In one embodiment, such as Figure 7 As shown, a display module is provided. The outer surface of the display area of ​​the display module has a texture. The display module includes a driving unit 10 and a light-emitting unit 20. The light-emitting element 20 is located in the display area. The light-emitting unit 20 includes a plurality of pixels 210, and the driving unit 10 is used to perform display compensation on each pixel 210 in the light-emitting unit 20 based on first compensation data.

[0154] The first compensation data is determined through the following steps:

[0155] The system acquires an image of the exterior surface of the display area when the display module is not lit; based on the image, it determines first compensation data for the display area of ​​the display module; wherein the first compensation data is used to perform display compensation on the display module.

[0156] For example, the appearance image information of the exterior surface can be captured by a camera, and then the camera is connected to a computer to transmit the appearance image information to the computer. The computer then performs the above steps to determine the first compensation data, and then burns the first compensation data into the display driver IC (DDIC) of the display module.

[0157] For example, a display driver chip may contain a resistor string. By adjusting the number of resistors between two gray levels, the display driver chip can adjust the voltage corresponding to each gray level. This is one specific method for implementing gamma tuning in a display driver chip. The display driver chip may have built-in drive codes corresponding to different gray levels. For example, code 0000-4095 corresponds to a voltage of 0.2-6.8V, or code 0000-4095 corresponds to a voltage of 3.5-6.8V. For instance, before gamma tuning, code 0000-4095 corresponds to a voltage of 0.2-6.8V, and after gamma tuning, code 0000-4095 corresponds to a voltage of 3.5-6.8V, thus adjusting the voltage range and achieving the effect of gamma tuning.

[0158] In this embodiment, the display module includes a driving unit 10 and a light-emitting unit 20. The driving unit 20 is used to perform display compensation on each pixel 210 in the light-emitting unit 20 based on the first compensation data. The first compensation data can offset the influence of the texture of the outer surface of the display module on the display effect, improve the uniformity of the display screen of the display module, and improve the display effect.
