Gray-scale voltage generating circuit and a liquid crystal display device using the same to reduce the crosstalk

摘要

This invention provides a thin film transistor liquid crystal display (TFT LCD: thin film transistor liquid crystal display) it relates to a, generating a reference voltage proportional to the distortion level of the common electrode voltage is distorted by the panel load, and the reference voltage and a direct current it is possible to eliminate the occurrence of crosstalk due to the distortion of the common electrode voltage by generating a gray level voltage using the power source.
