AI Technical Summary

Technical Problem

Existing Gamma adjustment methods have large detection accuracy errors at low gray levels and low brightness, which can easily lead to gray level transition discontinuity.

Method used

By dividing the grayscale of the first binding point into a high-precision detection brightness range and the grayscale of the second binding point outside the range, optical detection matching is used to obtain the data voltage value of the grayscale of the first binding point, and logical calculation is used to obtain the data voltage value of the grayscale of the second binding point, thus avoiding errors caused by insufficient optical detection precision.

Benefits of technology

It improves the detection accuracy under low brightness and low grayscale conditions, avoids grayscale transition discontinuity, and ensures the accuracy of data voltage values.

Abstract

This application discloses a gamma adjustment method, apparatus, device, and storage medium. The method includes: determining multiple first binding point gray levels and multiple second binding point gray levels based on the target brightness values ​​corresponding to each binding point gray level and the detection brightness range of the optical device; adjusting the data voltage value to match the actual brightness value with the target brightness values ​​corresponding to each first binding point gray level when displaying a monochrome image on the display panel; determining a step voltage value based on the data voltage values ​​corresponding to some of the first binding point gray levels; and calculating the data voltage value corresponding to each second binding point gray level based on the gray level difference between any first binding point gray level and each of the second binding point gray levels and the step voltage value. According to the embodiments of this application, the data voltage values ​​of some binding point gray levels can be obtained using a non-optical detection matching method, avoiding the impact of acquisition accuracy on the accuracy of the data voltage values ​​and improving the gray level transition discontinuity phenomenon under low brightness and low gray levels.
