Title: Driving circuit for display device
Inventor: TANAKA MANABU
IPC: G09G3/00
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the deterioration of the liquid crystal material of an active matrix type liquid crystal display device by halting the generation of scanning pulses for a prescribed period of time after the input of a power source. CONSTITUTION:The output signal of a power source circuit is raised to a high level by input of the power source. A control circuit 45 generates a control signal LOWQ of a high level when the output signal rises to the high level. The signal LOWQ resets a shift register 42. The output of the register 42 falls to a low level and the scanning pulses fall to the low level as well in the reset state. Then, the switching elements connected to line electrodes OG 1 to OG n for scanning turn off and voltages are not impressed to display picture elements even if the outputs are emitted from a row electrode driving circuit 46. The circuit 45 turns the signal LOWQ to the low level and the register 42 generates the scanning signal of the high level in response with a start pulse SPS and a clock signal CLS upon lapse of the prescribed period of time. The switching elements connected to the line electrodes OG 1 are thus successively turned on.
