FIELD: electrical engineering.
SUBSTANCE: invention relates to a liquid crystal display. Gamma voltage generation module for supplying a gamma voltage to a liquid crystal panel including a plurality of pixel blocks, each of the pixel blocks includes a main pixel region M and an additional pixel region S, reference voltage block, the first row of the resistive divider, and the second row of the resistive divider. Reference voltage unit supplies the reference voltages to the lines of the resistive divider. First line of the resistive divider is connected by a reference voltage block for dividing the reference voltages to form gamma voltages, corresponding to the gray levels from 0 to 255, and supplying gamma voltages to the main area of the pixels M. Second row of the resistive divider is connected to the reference voltage unit to divide the reference voltages to form gamma voltages corresponding to the gray levels from 0 to 255, and applying gamma voltages to the additional area of the pixels S. In the first and second rows of the resistive divider, the gamma voltage generation points at the gray levels 0, Gx, Gx + 1 and 255 are connected to the reference voltages.
EFFECT: technical result is to improve the quality of the display when the color shift is reduced.
