GAMMA CORRECTION METHOD FOR A DISPLAY DEVICE - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18096536 Titled 'GAMMA CORRECTION METHOD FOR A DISPLAY DEVICE'

Simplified Explanation

This abstract describes a method for adjusting the gamma (brightness) of a display device. The method involves determining voltage codes for different grayscale values based on a desired gamma value and color coordinate. These voltage codes are then used to create a lookup table. The method also involves determining a different set of voltage codes for the same grayscale values based on a correction measurement point. A color position correction value is calculated using these voltage codes, and gamma correction is performed using this value and the lookup table.


Original Abstract Submitted

A gamma correction method for a display device determines a first voltage code for a first color corresponding to each of grayscale values based on a target gamma value and a target color coordinate at a reference measurement point, generates a first lookup table including the first voltage code for the first color, determines a second voltage code for the first color corresponding to each of the grayscale values based on the target gamma value and the target color coordinate at a correction measurement point, generates a first color position correction value based on the first voltage code for the first color and the second voltage code for the first color, and performs gamma correction using the first color position correction value and the first lookup table.
