The Micro LED has the advantages of good stability, small size, power saving, wide color gamut, long service life and the like, and meanwhile inherits the advantages of low power, high color saturation, high reaction speed, strong contrast and the like of the LED. At present, a method for Gamma debugging a Micro LED product often can only be adjusted by manually adjusting a register of a driver Integrated Circuit (IC), which not only reduces the display efficiency of the product, but also prevents a user from obtaining a better visual experience.
Based on this, the present application hopes to provide a solution that can solve the above technical problem, and can implement automatic Gamma debugging on the Micro LED product, thereby effectively improving the efficiency of Gamma debugging on the Micro LED product, and the details thereof will be explained in the following embodiments.
The scheme of the application elaborates the related circuit structure of the Gamma debugging equipment and the specific flow of the related Gamma debugging method.
Please refer to fig. 1, which is a schematic structural diagram of a Gamma debugging device according to an embodiment of the present disclosure. As shown in fig. 1, the present application provides a Gamma debugging apparatus 100, which includes a brightness adjusting module 110 and a chromaticity adjusting module 120 electrically connected to the brightness adjusting module 110. The brightness adjustment module 110 is configured to adjust the display brightness of the display panel to a preset brightness, and the chromaticity adjustment module 120 is configured to adjust the display chromaticity of the display panel. It is understood that, in some embodiments, the display panel may be a Micro LED display panel, which is not limited thereto.
Please refer to fig. 2, which is a schematic structural diagram of the brightness adjusting module 110 of the Gamma debugging apparatus shown in fig. 1. As shown in fig. 2, the brightness adjustment module 110 includes a brightness determination unit 111, a brightness calculation unit 112, and a brightness debugging unit 113. The brightness determining unit 111 is electrically connected to the brightness calculating unit 112, and the brightness calculating unit 112 is electrically connected to the brightness debugging unit 113, that is, the brightness calculating unit 112 is electrically connected to the brightness determining unit 111 and the brightness debugging unit 113, respectively.
In this embodiment, the brightness determining unit 111 is configured to determine the maximum brightness of the white picture of the Gamma debugging apparatus 100, ensure that the white picture meets the preset brightness, and transmit the determined maximum brightness to the brightness calculating unit 112.
The brightness calculating unit 112 is configured to calculate and obtain target brightness values corresponding to different gray scales. Specifically, the brightness calculating unit 112 calculates target brightness values corresponding to different gray scales according to the gray scale, the Gamma value, the relational formula between the Gamma value and the gray scale, and the maximum brightness determined by the brightness determining unit 111. Wherein, the calculation formula of the target brightness value (i.e. the relational formula between Gamma value and gray scale) is:
Figure BDA0002984656990000061
wherein, L is the target brightness value, lmax is the maximum brightness, x is the gray scale, and r is the Gamma value. In practical applications, the display brightness is usually divided into 0 to 255 gray levels, and after the maximum brightness is determined, the black frame with the minimum brightness is calculated according to the brightness 0.

Specifically, in order to accurately determine which color has a large influence on the white coordinate, the color coordinate may be divided into three regions: the white color image comprises a blue area, a red area and a green area, wherein when the color coordinate is x less than 0.32 and y less than 0.32, the white color image is judged to be the blue area, and the white color coordinate is mainly influenced by blue color; when the color coordinate is x is more than 0.32 and y is less than 0.55, the color coordinate is judged to be a red area, and the white coordinate is mainly influenced by red; when the color coordinate is x < 0.32 and y > 0.32, it is judged as a green region, and the white coordinate is mainly affected by green. For example, when the white coordinates are (0.282 ), the white coordinates are mainly affected by blue as shown in fig. 4.
The chrominance debugging unit 124 is configured to adjust chrominance corresponding to the gray scale. Specifically, the chromaticity debugging unit 124 is configured to adjust the brightness value of the color in the white picture according to the color affecting the white coordinate obtained by the chromaticity calculating unit 123, and change the ratio of the color in RGB. For convenience of understanding and explanation, the adjustment of the blue brightness value of the white screen is specifically described as an example, when in adjustment, firstly, the adjustment is performed with 1% of the Gamma register as the precision, the blue value with a large influence on the white coordinate in the Gamma register corresponding to the gray scale is adjusted, and then the blue brightness value is gradually decreased until the difference between the actually measured color coordinate (x, y) and the set color coordinate of the white screen of the Gamma debugging device 100 is within ± 0.01; when the difference between the actually measured color coordinates (x, y) and the set color coordinates of the white picture of the Gamma debugging device 100 is less than 1 percent, the adjustment with the precision of 1 percent is stopped, and the adjustment with the precision of 1/1000 is carried out until the error is within +/-0.003.

wherein, L is the target brightness value, lmax is the maximum brightness, x is the gray scale, and r is the Gamma value. In practical applications, the display brightness is usually divided into 0 to 255 gray levels, and after the maximum brightness is determined, the black picture with the minimum brightness is calculated according to the brightness 0.
