Embodiment Construction
[0050] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0051] The main solution of the embodiment of the present invention is: the adjustment device determines the target binding point in the display lookup table of the gamma voltage corresponding to the display screen, and obtains the initial register value corresponding to the target binding point and the target spectral tristimulus value, so The gray scale of the preset gray scale value in the display lookup table is a binding point, and the number of the binding points is less than the number of gray scales, and the register value includes the red register value, the green register value and the blue register value; determine the The predicted value corresponding to the initial register value, and adjust the initial register value according to the predicted value to obtain the first register value; determine the first ...

The invention discloses a method for adjusting the gamma voltage and white balance of a display screen, comprising: an adjustment device determines a target binding point in a display lookup table of the gamma voltage corresponding to the display screen, and obtains an initial register corresponding to the target binding point value and the target spectral tristimulus value; determine the predicted value corresponding to the initial register value, and adjust the initial register value according to the predicted value to obtain the first register value; determine the first register value according to the first register value and the target spectral tristimulus value to meet the convergence condition, save the first register value as the register value after the adjustment of the target binding point; save the first register value as the register value after the adjustment of the target binding point; Re-determine the target binding point in the adjusted binding point, and return to the step of obtaining the initial register value corresponding to the target binding and the target spectral tristimulus value. The invention also discloses a regulating device and a medium. The adjustment efficiency of the gamma voltage and the white balance of the display screen of the invention is high.
Description
technical field [0001] The invention relates to the technical field of display screens, in particular to an adjustment device, a method and a medium for adjusting gamma voltage and white balance of a display screen. Background technique [0002] In the production process of display screens, gamma voltage and white balance correction are very critical process links, which can ensure that the display screen has a good visual perception. The commonly used gamma voltage adjustment methods include linear interpolation and coefficient matrix method. The accuracy of these two methods is very different between the high gray scale interval and the low gray scale interval, which leads to very low gamma voltage adjustment efficiency. Contents of the invention [0003] The main purpose of the present invention is to provide an adjustment device, a method and a medium for adjusting gamma voltage and white balance of a display screen, aiming at solving the problem of low gamma voltage a...
