LIQUID CRYSTAL DISPLAY CONTROL CIRCUIT

摘要

PROBLEM TO BE SOLVED: To suppress the generation of a display unevenness due to fluctuations of data enable signals. SOLUTION: A liquid crystal display control circuit 1 inputs a data enable signal DE being in synchronization with display data of a line unit from a computer 3 to control a liquid crystal display device 2. A gate driving signal to be outputted by a gate driver 23 is operated by a vertical clock signal VCK being in synchronization with the rising of the DE and a gate enable signal generating circuit 10 is provided in the liquid crystal display control circuit 1 in order to prevent fluctuations of charging periods of pixel electrodes due to the delay of the timing of the rising of the DE and the delay of the VCK after the last line to prohibit the outputting of the prolonged portion of the pulse of the gate driving signal due to the delay.
