GAMMA CORRECTION METHOD FOR A DISPLAY DEVICE: abstract simplified (18096536)

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

Simplified Explanation

This abstract describes a method for adjusting the gamma correction of a display device. Gamma correction is a technique used to ensure accurate color representation on a display. The method involves determining voltage codes for different grayscale values based on a target gamma value and color coordinates at reference and correction measurement points. These voltage codes are then used to generate a lookup table for gamma correction. Additionally, a color position correction value is calculated based on the voltage codes, and this value is used along with the lookup table to perform gamma correction.

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.
