Abstract
An apparatus comprises an LCD with a gamma correction circuit which compensates for the non-linear characteristics of gamma. The gamma correction circuit includes a memory device for storing programmed data. The programmed data is used to make gamma constant and to make the light transmissivity vary linearly with the input image data. The memory device may be a ROM (Read Only Memory) or a RAM (Random Access Memory). The programmed data may be changed according to the characteristics of the liquid crystal being driven.
