Specific Embodiments

[0041] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the drawings.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more unless otherwise specifically defined.

[0043] First, the nouns appearing in this text are explained as follows:

[0044] Mini-LED: Sub-millimeter Light Emitting Diode. Mini-LED backlight display technology provides fine pixel control through a small-sized LED chip array, thereby achieving higher contrast and clearer image display. As Figure 1 shown, the Mini-LED display system mainly includes an SoC chip 101, a display control device 102, a backlight control device 103, a liquid crystal screen 104, and a backlight unit 105. Among them:

[0045] SoC chip 101: System-on-Chip, a system-level chip, is the core processing unit of the system, responsible for running the operating system, processing graphics rendering, generating video signals, and transmitting the processed image data to the display control device 102 through transmission protocols such as VBO (V-by-One) or eDP (Embedded DisplayPort). Some SoC chips 101 may also integrate a Display Controller to directly manage the display timing and signal output.

[0046] Display control device 102: Receives the video signal from the SoC chip 101 and converts it into a driving signal (such as row / column scanning signals) that the liquid crystal screen 104 can recognize. The TCON (Timing Controller) is a key component used to parse images, generate driving timing, and analyze the light and dark distribution. TCON synchronous control: Refreshes the deflection of liquid crystal molecules (to display images) through the source / gate driver IC. Sends backlight zone data to the backlight control device 103 via I2C to light up the backlight unit 105.

[0047] Backlight control device 103: Includes a backlight control chip and a backlight driver chip. The backlight control chip receives the backlight zone data from the TCON, runs a dimming algorithm, and outputs a PWM or analog voltage signal to adjust the backlight brightness; The backlight driver chip: Converts the control signal into a constant current output to directly drive the LED beads. Usually, at least one backlight control chip is required for each screen, which acts like a "main control switch" to control the backlight source. The backlight driver chip can be divided into types such as single-channel, 4-channel, 8-channel, 16-channel, etc. One channel corresponds to one backlight zone, and one backlight zone can cover multiple LED beads. The backlight control chip achieves zonal control and fine adjustment of the backlight source by precisely controlling the state of the backlight driver chip.

[0048] Liquid crystal screen 104: Receives the signal from the TCON through the source / gate driver IC, controls the deflection of liquid crystal molecules to modulate the light transmittance, and forms an image.

[0049] Backlight unit 105: Emits light under the control of the backlight control device 103.

[0050] In a Mini-LED backlight system, the phenomenon that light signals or light rays leak or interfere with adjacent areas unexpectedly during transmission is called optical crosstalk. Optical crosstalk can lead to uneven display, color distortion, or a decrease in contrast. Currently, physical isolation or increasing the driving frequency is used to alleviate color bleeding, but there are problems such as high power consumption, complex hardware, and increased costs.

[0051] Based on the above technical problems, an embodiment of the present application provides a display control method, which can be applied to Figure 1 the application scenario shown. Taking the application of this method to Figure 1 the application scenario shown as an example, the display of the Mini-LED display system in Figure 1 is controlled. The display control method provided by the embodiment of the present application can be applied to the display control device 102 in the Mini-LED display system, and can also be applied to other electronic devices outside the Mini-LED display system to control the display control of the Mini-LED display system. The execution subject of the display control method provided by the embodiment of the present application can obtain the display data of each frame of the display screen to execute the display control method.

[0052] In one embodiment, as shown in Figure 2 , a display control method is provided. Taking the application of this method to the display control device 102 in Figure 1 as an example, the method includes the following steps:

[0053] Step 202, determine a target adjustment area located in the color boundary area of the display screen according to the display screen;

[0054] Step 204, determine the backlight adjustment coefficient and the display compensation coefficient of the target adjustment area according to the actual brightness value of the target adjustment area;

[0055] Step 206, determine the backlight compensation brightness of the target area according to the backlight adjustment coefficient and the display compensation coefficient, and determine the display compensation voltage of the target adjustment area according to the display compensation coefficient;

[0056] Step 208, display the display screen according to the backlight compensation brightness and the display compensation voltage.

[0057] The display screen refers to the screen that the Mini-LED display system is about to display. The display screen in the embodiment of the present application includes the corresponding display data of the display screen. In the Mini-LED display system, the SoC chip 101 processes the received external video signal and generates a video signal to send to the display control device 102. The TCON in the display control device 102 generates a driving timing and analyzes the light and dark distribution, and sends signals to the backlight control device 103 and the liquid crystal screen 104 to jointly realize the display of the screen.

[0058] Among them, the video signal includes the display data of each frame of the display screen. The display data of the display screen includes various information such as color and brightness. Among them, the color data determines the color performance of each pixel point, usually including the intensity values of three primary colors: red (R), green (G), and blue (B). These values together determine the final color of the pixel point. The brightness data represents the brightness level of each pixel point, which affects the overall brightness and contrast of the image. In addition to color and brightness data, the display data may also include other auxiliary information, such as synchronization signals, image resolution, refresh rate, etc. These information help the display screen correctly interpret and display the image.

[0059] Specifically, the display control device 102 is mainly responsible for controlling how the pixel points on the display screen display colors. Therefore, the data it receives are mainly color data and some auxiliary data (such as synchronization signals, image resolution, etc.). These data directly determine the color and position of each pixel point on the screen. The backlight control device 103 is responsible for controlling the light emission of the Mini-LED backlight source. The data it receives are mainly brightness data and related control signals. These brightness data are used to guide the backlight control chip how to adjust the brightness of each Mini-LED to achieve more refined zoned backlight control and higher contrast. In addition, the backlight control device 103 may also receive some instructions from the SoC chip 101 or other control chips to adjust the overall brightness or mode of the backlight.

[0060] In step 202, the display control device 102 identifies the display data of each frame of the received display screen and determines the target adjustment area in each frame of the display screen.

[0061] Among them, the target adjustment area refers to the area where optical crosstalk exists, that is, the area located at the color junction. Optical crosstalk refers to the phenomenon in the display screen that due to various factors (such as light scattering, reflection, refraction, etc.), the light between adjacent pixels or regions interferes with each other, thus affecting the image quality and clarity. As a result, the target adjustment area includes the affected and the influencing areas. Usually, the target adjustment areas appear in pairs. For example, red is a highly sensitive color, and the red area and other areas adjacent to the red area can both be target adjustment areas. Correspondingly, for the target adjustment area, its display parameters can be adjusted positively or negatively.

[0062] The actual brightness value refers to the display brightness of the initial control included in the display data of each frame of the display screen. The actual brightness value is sent from the display control device 102 to the backlight control device 103. The actual brightness value of the target adjustment area refers to the actual brightness values of all backlight partitions involved in the target adjustment area. It can be understood that since the target adjustment area refers to the area where optical crosstalk may exist, and the determination of this area is related to the actual content displayed in the display screen, therefore, it is very likely that the target adjustment area will not completely coincide with a single backlight partition. Unless the target adjustment area is completely within a backlight partition, otherwise, it will correspond to multiple backlight partitions. When adjusting the target adjustment area, it includes adjusting the brightness or other parameters of all the backlight partitions involved to ensure the complete presentation of the picture.

[0063] The backlight adjustment coefficient refers to the coefficient for adjusting the backlight parameters of the corresponding backlight partition to avoid optical crosstalk; the display compensation coefficient refers to the coefficient for compensating the display of the display screen to make up for the impact brought by the backlight adjustment after the backlight adjustment. It can be known from the technical background that in the Mini-LED display system, the display of each frame of the picture is jointly determined by the backlight controlled by the backlight control device 103 and the liquid crystal molecules in the liquid crystal screen 104. Therefore, in this embodiment, in order to alleviate the optical crosstalk between adjacent LEDs, the control parameters of both the backlight unit and the liquid crystal molecules are adjusted.

[0064] Specifically, by analyzing each frame of the display screen, the target adjustment area to be adjusted in the display screen is determined. For example, in the color boundary area (such as the junction of red and white), the brightness of the edge partition of the highly sensitive color (such as red) is multiplied by the first backlight adjustment coefficient g to reduce its brightness overflow; the brightness of the adjacent partition (such as white) is multiplied by the second backlight adjustment coefficient k, where 0 < g < 1 and k > g, to balance the visual perception difference. Correspondingly, the LCD display voltage of the display screen is synchronously adjusted. The red edge voltage data is multiplied by the first display compensation coefficient a, and the white edge is multiplied by the second display compensation coefficient b, where b < a and 0 < b < 1. The liquid crystal deflection angle is updated through the determined display compensation voltage, and the respective gray levels of the display screen at the red and white color edges are changed to suppress the color bleeding effect.

[0065] The display control method provided by the above embodiments determines a target adjustment area located in the color boundary area of the display screen according to the display screen; determines a backlight adjustment coefficient and a display compensation coefficient for the target adjustment area according to the actual brightness value of the target adjustment area; determines the backlight compensation brightness of the target area according to the backlight adjustment coefficient, and determines the display compensation voltage of the target adjustment area according to the display compensation coefficient; and displays the display screen according to the backlight compensation brightness and the display compensation voltage. By analyzing the colors of the display screen, the target adjustment area with optical crosstalk in the display screen is determined, and the display of the target adjustment area is adjusted according to its actual display brightness to avoid affecting adjacent areas or reducing the influence of adjacent areas on it, thereby effectively reducing optical crosstalk.

[0066] In one of the embodiments, as Figure 3 shown, determining the target adjustment area located in the color boundary area of the display screen according to the display data includes:

[0067] Step 302, identifying the color data of each pixel point in the display screen;

[0068] Step 304, determining the target adjustment area according to the color data of each pixel point and the color data of the reference pixel points adjacent to each pixel point.

[0069] Among them, the color data of the pixel point is a parameter associated with optical crosstalk. The display data of the pixel point is generated by the SoC chip 101 and sent to the display control device 102 after processing. The TCON in the display control device 102 converts it into a driving signal for the liquid crystal screen 104 and the backlight control device 103. By identifying and comparing the color data of each pixel point in each frame of the screen, the target adjustment area in the display screen is determined.

[0070] Specifically, the color data of each pixel point is compared with the color data of its adjacent reference pixel points to determine whether optical crosstalk will occur, so as to determine the area where optical crosstalk will occur. Each pixel point has at least 2 reference pixel points. For example, the shape of the display screen is rectangular, and the LEDs in the backlight and the liquid crystal cells in the display screen are both arranged in a matrix. For the pixel points at the four corners of the display screen, there are 2 reference pixel points, the reference pixel points of the edge pixel points are 3, and the reference pixel points of other pixel points are 4. By comparing the color data of each pixel point with the color data in the reference pixel points, it can be judged whether optical crosstalk will occur.

[0071] In the method provided by the above embodiments, by judging the color data of each pixel point and combining the position coordinates of each pixel point, the target adjustment area can be quickly determined.

[0072] In one embodiment, the number of reference pixel points is multiple. According to the color data of each pixel point and the color data of the reference pixel points adjacent to each pixel point, determining the target adjustment area includes:

[0073] Traverse each pixel point in the display screen. For the traversed pixel point, when it is determined that there is at least one reference pixel point with the same color as the pixel point according to the color data of the pixel point and the color data of the corresponding reference pixel point, determine the pixel point as a target pixel point;

[0074] After completing the traversal of each pixel point in the display screen, determine multiple target pixel points;

[0075] Determine the target adjustment area according to the multiple target pixel points.

[0076] In the display screen, traverse each pixel point. By comparing the color data of the pixel point with the color data of its corresponding reference pixel point, it can be determined whether the colors between the pixel point and its corresponding reference pixel point are the same, so as to determine whether there is optical crosstalk.

[0077] When comparing the color data of two pixel points, an appropriate comparison method can be selected according to the format of the color data. If the color space of the display screen is RGB, judge by calculating the Euclidean distance between two pixel points (R1, G1, B1) and (R2, G2, B2). Specifically, when the Euclidean distance is greater than the preset distance, it is considered that the colors are different. If the color space of the display screen is HSV, directly judge whether the colors are the same according to whether the difference between the color data H1 and H2 of the two pixel points is greater than the preset difference.

[0078] Therefore, when performing an overall analysis of the screen content of the display screen, the analysis of each pixel point can be associated with the analysis results of its adjacent reference pixel points, without analyzing each adjacent pixel point of each pixel point.

[0079] For example, start analyzing from the first pixel point in the upper left corner of the display screen. When analyzing subsequent pixel points, only need to analyze the adjacent pixel points on the right and below as reference pixel points to obtain the analysis results of the entire screen.

[0080] After the traversal is completed, multiple target pixel points in the display screen can be obtained. According to the coordinates of the multiple target pixel points, the target adjustment area can be determined. Since the colors between the target pixel points are also different, correspondingly, the adjustments for different colors are also different. Therefore, in one embodiment, determining the target adjustment area according to the multiple target pixel points includes:

[0081] Target pixel points with the same and adjacent color data are determined as a target adjustment area.

[0082] In this embodiment, a target adjustment area is a closed area, and within this area, the backlight adjustment coefficients of all pixel points are the same, and the display compensation coefficients are the same. For example, if a target adjustment area is determined to be a red area at the junction of red and white in the display screen, then the pixel points within the entire area can be adjusted in the same way.

[0083] In another embodiment, if a target adjustment area is a closed area, and within this area, the backlight adjustment coefficients of all pixel points are the same, and the display compensation coefficients are the same, but the colors of the adjacent pixel points of two pixel points in this area are different. That is to say, relatively speaking, the degree or effect of optical crosstalk at the two pixel points will be different. Therefore, when determining the target adjustment area based on all target pixel points, the colors of the adjacent pixel points when determining the target pixel points will also be considered. For example, target pixel points with red color data, some are at the junction of red and white, and are regarded as one target adjustment area; others are at the junction of red and yellow, and are regarded as another target adjustment area. Therefore, there are usually multiple target adjustment areas in the embodiments of the present application.

[0084] In the method provided in the above embodiments, the target adjustment area is determined through color data, the display of the display screen is analyzed in detail, and precise adjustment is performed for each target adjustment area, which can better eliminate optical crosstalk.

[0085] In one of the embodiments, as Figure 4 shown, determining the backlight adjustment coefficient and the display compensation coefficient of the target adjustment area according to the actual brightness value of the target adjustment area includes:

[0086] Step 402, determining the backlight adjustment coefficient of each backlight partition according to the actual brightness value of each backlight partition corresponding to the target adjustment area;

[0087] Step 404, determining the corresponding display compensation coefficient of each backlight partition according to the backlight adjustment coefficient of each backlight partition.

[0088] The target adjustment area in the display screen corresponds to at least one backlight partition in the backlight source. According to the actual brightness value of each backlight partition and the color of each pixel point in the target adjustment area, the backlight adjustment coefficient of each corresponding backlight partition is determined. The backlight adjustment coefficients for different colors are different, and the backlight adjustment coefficients at different brightness levels are also different. Therefore, the backlight adjustment coefficient corresponding to each backlight partition can be determined by means of a look-up table, where the look-up table can be determined by historical display data and can also be determined by simulated display data.

[0089] In one embodiment, determining a display compensation coefficient corresponding to each backlight partition according to the backlight adjustment coefficient of each backlight partition includes:

[0090] Based on the target mapping relationship and the backlight adjustment coefficient of each backlight partition, determining the display compensation coefficient corresponding to each backlight partition; the target mapping relationship includes: the mapping relationship between the backlight adjustment coefficient and the display compensation coefficient.

[0091] It should be understood that although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps has no strict order limit, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least a part of other steps or steps or stages in other steps.
