Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically to a method and apparatus for adjusting the brightness uniformity of a mini-LED display. Background Technology

[0002] Traditional LCD screens consist of layers including a backlight panel, a diffuser panel, a liquid crystal panel (LCD), color filters, and polarizers. The backlight panel provides the light source for the display. The LCD controls the transmittance of the light source at each pixel location based on the pixel value of the displayed image. After passing through the color filters and polarizers, the screen can display different colors to show the content the user wants to view. The monitor needs to ensure uniform brightness to guarantee its standard display effect. Traditional LCD screens have evenly distributed LED beads on the backlight panel to provide the light source. Because the brightness control of all LED beads is uniform—they can only be on and off simultaneously—the brightness uniformity of traditional LCD monitors is usually adjusted by adjusting the liquid crystal at each position on the LCD panel. However, this method limits the control range of the liquid crystal to some extent, reducing the color gamut area of ​​the monitor.

[0003] With the continuous development and advancement of modern electronic component technology, mini-LED displays are gradually entering the public eye. Compared to traditional LCD displays, the biggest difference in mini-LED displays is that their backlight panels are evenly divided into hundreds or thousands of rectangular backlight areas, and the brightness of each area can be independently controlled. Therefore, the brightness uniformity adjustment of mini-LED displays differs from that of traditional LCD displays. Even with default adjustment, mini-LED displays still exhibit uneven brightness across their backlight areas. Therefore, how to quickly adjust the brightness of each backlight area of ​​the display to a basically consistent level is a problem that urgently needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method and apparatus for adjusting the brightness uniformity of a mini-led display, which aims to increase the color gamut of the mini-led display, improve the brightness uniformity of the display, and thus enable the display to have higher display capabilities.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention provides a method for adjusting the brightness uniformity of a mini-LED display, wherein the backlight panel of the mini-LED display is uniformly divided into several backlight areas, and the backlight value of each backlight area is adjustable, including:

[0010] Under the set default backlight value, obtain the default brightness value for each backlight area;

[0011] Calculate the average brightness of each backlight area based on the default brightness value of each backlight area;

[0012] The target backlight value is calculated based on the average brightness of each backlight area and the maximum brightness of the backlight area.

[0013] Set the backlight value of all backlit areas to the target backlight value.

[0014] The further technical solution is: the set default backlight value is less than the set maximum backlight value.

[0015] The further technical solution is: the default backlight value is set to be half of the maximum backlight value.

[0016] The further technical solution is as follows: the formula for calculating the average brightness of each backlight area is:

[0017] Among them, Y k Let m' represent the average brightness of the k-th backlight region, where m' = M / m and n' = N / n. M and N represent the number of rows and columns of brightness data, m and n represent the number of rows and columns of the backlight region, m' represents the number of brightness data points per row in each backlight region, and n' represents the number of brightness data points per column in each backlight region. ij This represents the brightness data in the i-th row and j-th column of the k-th backlight area.

[0018] The further technical solution is as follows: The formula for calculating the target backlight value is:

[0019] Among them, dstL k K represents the target backlight value for each backlight area, K = m * n represents the total number of backlight areas, and S represents the maximum backlight value.

[0020] Secondly, the present invention also provides a brightness uniformity adjustment device for a mini-led display, wherein the backlight panel of the mini-led display is uniformly divided into several backlight areas, and the backlight value of each backlight area is adjustable, including a first adjustment unit, a first acquisition unit, a second adjustment unit, a second acquisition unit, a first calculation unit, a second calculation unit, and a setting unit;

[0023] The second adjustment unit is used to adjust the backlight value of all backlight areas of the display to the default backlight value;

[0024] The second acquisition unit is used to acquire the default brightness value of each backlight area under the set default backlight value conditions;

[0025] The first calculation unit is used to calculate the average brightness of each backlight area based on the default brightness value of each backlight area;

[0026] The second calculation unit is used to calculate the target backlight value based on the average brightness of each backlight area and the maximum brightness of the backlight area;

[0028] Thirdly, the present invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the above-described method for adjusting the brightness uniformity of a mini-led display.

[0029] Fourthly, the present invention also provides a computer-readable storage medium storing a computer program, the computer program including program instructions, which, when executed by a processor, cause the processor to perform the above-described method for adjusting the brightness uniformity of a mini-led display.

By obtaining the maximum brightness of the backlight area of ​​the display and the default brightness of each backlight area, the average brightness of each backlight area of ​​the display is calculated based on the default brightness of the display. Using the average brightness as the target, the target backlight value of each backlight area is calculated, and the backlight of each area is adjusted so that the brightness value of each backlight area is adjusted to the target backlight value, so as to achieve brightness consistency of each area of ​​the mini-LED display. This method can remove the limitation of the control range of the liquid crystal in traditional LCD displays to maintain the brightness uniformity of the screen, thereby increasing the color gamut of the display and improving the display capability.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0040] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0041] like Figure 1 As shown, this embodiment of the invention provides a method for adjusting the brightness uniformity of a mini-led display. The backlight panel of the mini-led display is uniformly divided into several backlight areas, and the backlight value of each backlight area is adjustable. The method includes the following steps: S10-S70.

[0042] S10. Adjust the backlight value of all backlight areas of the monitor to the maximum backlight value.

[0043] Since the backlight values ​​of each backlight area on the monitor's backlight panel are adjustable, the backlight values ​​of each area can be adjusted to the maximum value through either hardware or software control. For hardware control, the backlight brightness can be changed by adjusting the voltage or current of the backlight controller. Increasing the voltage or current maximizes the backlight brightness, thus adjusting the backlight values ​​of all backlight areas to the maximum. For software control, the backlight values ​​can be adjusted through the monitor's control interface or using the monitor's control software. Selecting the maximum backlight value in the settings or adjusting the brightness slider to the maximum position will adjust the backlight values ​​of all backlight areas to the maximum.

[0044] S20. Under the condition of the set maximum backlight value, obtain the maximum brightness of the backlight area.

[0045] A two-dimensional color analyzer is generally used to obtain brightness data for the backlight area.

[0046] It should be noted that the maximum brightness of the backlight area obtained here refers to the maximum brightness of a specific backlight area among all backlight areas. Since each backlight area is at its maximum brightness under the set maximum backlight value, the maximum brightness of the backlight area can be obtained by comparison.

[0047] S30. Adjust the backlight value of all backlight areas of the monitor to the default backlight value.

[0048] The default backlight value is set to be less than the maximum backlight value. In this embodiment, the default backlight value is set to be half of the maximum backlight value. Of course, in other embodiments, the default backlight value is set to be one-third or one-quarter of the maximum backlight value, etc.

[0049] S40. Under the set default backlight value, obtain the default brightness value of each backlight area.

[0050] A two-dimensional color analyzer is generally used to obtain brightness data for the backlight area.

[0051] It should be noted that obtaining the default brightness of each backlight area here refers to the default brightness of each backlight area in all backlight areas.

[0052] S50. Calculate the average brightness of each backlight area based on the default brightness value of each backlight area.

[0053] In mini-LED displays, each backlight area is typically illuminated by multiple backlight sources. Since the backlight sources in different backlight areas may vary, their brightness may differ. For calculation purposes, the brightness distribution can be divided into corresponding regions according to the distribution of the backlight areas (for example, if there are m rows and n columns, with a total of K backlight areas, the brightness distribution of the display is divided into m*n regions). The average brightness of each backlight area is calculated as follows:

[0054] Among them, Y k Let m' represent the average brightness of the k-th backlight area, where m' = M / m and n' = N / n. M and N represent the number of rows and columns of brightness data, m and n represent the number of rows and columns of the backlight area, m' represents the number of brightness data points per row in each backlight area, and n' represents the number of brightness data points per column in each backlight area (i.e., the backlight format). ij This represents the brightness data in the i-th row and j-th column of the k-th backlight area.

[0055] S60. Calculate the target backlight value based on the average brightness of each backlight area and the maximum brightness of the backlight area.

[0056] The average brightness of the backlight area refers to the average brightness value of all backlight areas, reflecting the average brightness level of each area. The maximum brightness of the backlight area, on the other hand, represents the area with the highest brightness among all backlight areas. By analyzing these parameters, such as the average and maximum brightness, we can gain an understanding of the current backlight status of the display. A low average brightness may mean that the overall screen brightness is too low, while a low maximum brightness indicates that some areas of the backlight are insufficiently bright. Based on this information, a target backlight value can be calculated, meaning the appropriate brightness level that each backlight area can achieve, to ensure brightness consistency across all backlight areas of the mini-LED display.

[0057] The formula for calculating the target backlight value is as follows:

[0058] Among them, dstL k K represents the target backlight value for each backlight area, K = m * n represents the total number of backlight areas, and S represents the maximum backlight value.

[0059] S70, Set the backlight value of all backlight areas to the target backlight value.

[0060] When the backlight value of all backlight areas is set to the target backlight value, the brightness uniformity adjustment of the mini-LED is completed, and the brightness consistency of each area of ​​the mini-LED display is achieved. This method can remove the limitation on the control range of the liquid crystal in traditional LCD displays to maintain the brightness uniformity of the screen, thereby increasing the color gamut of the display and improving the display capability.

[0061] like Figure 4 As shown, Figure 4 This is a comparison image showing the brightness uniformity before and after adjustment. The left image is the image before brightness uniformity adjustment, and the right image is the image after brightness uniformity adjustment. Figure 4 It can be seen that after brightness uniformity adjustment, the brightness of the display area of ​​the monitor is uniformly distributed overall.

[0062] Corresponding to the above-described method for adjusting the brightness uniformity of a mini-led display, this embodiment of the invention also provides a device for adjusting the brightness uniformity of a mini-led display.

[0063] like Figure 2As shown, the mini-LED display brightness uniformity adjustment device 100 includes a first adjustment unit 110, a first acquisition unit 120, a second adjustment unit 130, a second acquisition unit 140, a first calculation unit 150, a second calculation unit 160, and a setting unit 170.

[0064] The first adjustment unit 110 is used to adjust the backlight value of all backlight areas of the display to the maximum backlight value.

[0065] Since the backlight values ​​of each backlight area on the monitor's backlight panel are adjustable, the backlight values ​​of each area can be adjusted to the maximum value through either hardware or software control. For hardware control, the backlight brightness can be changed by adjusting the voltage or current of the backlight controller. Increasing the voltage or current maximizes the backlight brightness, thus adjusting the backlight values ​​of all backlight areas to the maximum. For software control, the backlight values ​​can be adjusted through the monitor's control interface or using the monitor's control software. Selecting the maximum backlight value in the settings or adjusting the brightness slider to the maximum position will adjust the backlight values ​​of all backlight areas to the maximum.

[0066] The first acquisition unit 120 is used to acquire the maximum brightness of the backlight area under the condition of a set maximum backlight value.

[0067] A two-dimensional color analyzer is generally used to obtain brightness data for the backlight area.

[0068] It should be noted that the maximum brightness of the backlight area obtained here refers to the maximum brightness of a specific backlight area among all backlight areas. Since each backlight area is at its maximum brightness under the set maximum backlight value, the maximum brightness of the backlight area can be obtained by comparison.

[0069] The second adjustment unit 130 is used to adjust the backlight value of all backlight areas of the display to the default backlight value.

[0070] The default backlight value is set to be less than the maximum backlight value. In this embodiment, the default backlight value is set to be half of the maximum backlight value. Of course, in other embodiments, the default backlight value is set to be one-third or one-quarter of the maximum backlight value, etc.

[0071] The second acquisition unit 140 is used to acquire the default brightness value of each backlight area under the set default backlight value.

[0072] A two-dimensional color analyzer is generally used to obtain brightness data for the backlight area.

[0073] It should be noted that obtaining the default brightness of each backlight area here refers to the default brightness of each backlight area in all backlight areas.

[0074] The first calculation unit 150 is used to calculate the average brightness of each backlight area based on the default brightness value of each backlight area.

[0075] In mini-LED displays, each backlight area is typically illuminated by multiple backlight sources. Since the backlight sources in different backlight areas may vary, their brightness may differ. For calculation purposes, the brightness distribution can be divided into corresponding regions according to the distribution of the backlight areas (for example, if there are m rows and n columns, with a total of K backlight areas, the brightness distribution of the display is divided into m*n regions). The average brightness of each backlight area is calculated as follows:

[0076] Among them, Y k Let m' represent the average brightness of the k-th backlight area, where m' = M / m and n' = N / n. M and N represent the number of rows and columns of brightness data, m and n represent the number of rows and columns of the backlight area, m' represents the number of brightness data points per row in each backlight area, and n' represents the number of brightness data points per column in each backlight area (i.e., the backlight format). ij This represents the brightness data in the i-th row and j-th column of the k-th backlight area.

[0077] The second calculation unit 160 is used to calculate the target backlight value based on the average brightness of each backlight area and the maximum brightness of the backlight area.

[0078] The average brightness of the backlight area refers to the average brightness value of all backlight areas, reflecting the average brightness level of each area. The maximum brightness of the backlight area, on the other hand, represents the area with the highest brightness among all backlight areas. By analyzing these parameters, such as the average and maximum brightness, we can gain an understanding of the current backlight status of the display. A low average brightness may mean that the overall screen brightness is too low, while a low maximum brightness indicates that some areas of the backlight are insufficiently bright. Based on this information, a target backlight value can be calculated, meaning the appropriate brightness level that each backlight area can achieve, to ensure brightness consistency across all backlight areas of the mini-LED display.

[0079] The formula for calculating the target backlight value is as follows:

[0080] Among them, dstL k K represents the target backlight value for each backlight area, K = m * n represents the total number of backlight areas, and S represents the maximum backlight value.

[0081] Setting unit 170 is used to set the backlight value of all backlight areas to the target backlight value.

[0082] When the backlight value of all backlight areas is set to the target backlight value, the brightness uniformity adjustment of the mini-LED is completed, and the brightness consistency of each area of ​​the mini-LED display is achieved. This method can remove the limitation on the control range of the liquid crystal in traditional LCD displays to maintain the brightness uniformity of the screen, thereby increasing the color gamut of the display and improving the display capability.

[0083] like Figure 4 As shown, Figure 4 This is a comparison image showing the brightness uniformity before and after adjustment. The left image is the image before brightness uniformity adjustment, and the right image is the image after brightness uniformity adjustment. Figure 4 It can be seen that after brightness uniformity adjustment, the brightness of the display area of ​​the monitor is uniformly distributed overall.
