Title: Lcd module liquid crystal driving power circuit
Inventor: HAKE AKEMI
IPC: G09G3/36
Filed: 1993-04-01
Abstract: PURPOSE:To obtain a liquid crystal driving power source which is stable even if any influence of a noise is exerted upon a reference voltage to a boosting IC and to improve the distortion of a liquid crystal driving waveform due to variation in voltage by composing a smoothing circuit of a resistance and a capacitor. CONSTITUTION:The boosting IC is a DC-DC converter, R is a resistance, and C is a capacitor; and R and C constitute an R-C series circuit. A terminal RV1 of the IC is connected to a reference voltage in a module and a terminal RV2 is supplied with an external reference voltage. Thus, the R-C series circuit is inserted and sufficient noise removal is performed even if the electric conductor is long, so the boosting circuit reference voltage which is stable can be supplied even when the arrangement of the boosting IC is not limited specially. Consequently, sufficient level smoothing is performed even by inserting the resistance for the liquid crystal driving voltage outputted by the boosting IC with the reference voltage when the capacity of the smoothing capacitor is small, the mount area is reduced by decreasing the capacity, and the stable liquid crystal driving waveform can be supplied.
