This discharge operation is performed simultaneously for all output pins. (2) Timing of output discharge and video signal sampling The output discharge period (period “H” of the internal discharge signal DIS) is after3 cycles of clock CK from the “H” period of start pulse SPD.

Therefore it is necessary to input the suitable voltage to Vbl pin and Vb2 pin. Set the voltage value to an optimum value in the range of Vcc to GND as shown in the diagram below, fully evaluating the current consumption, picture quality, etc. (Example of biascircuit) t----r> Vbl, Vb2 Set the resistance to Rl +R2=50 kfI (2) Setting of Input pins Since 6 pins of SP, CK, CTR, MODE, Vbl , and Vb2 of the input pins are not pulled up or pulled down in the LSI, never use these 6 pins in the “OPEN” condition. Since VA, VB, and VC pins are for inputting video signals, necessary video signals must be input always. Except VA, VB, VC, Vbl , Vb2, SP, CK, CTR, and MODE, all other input pins are pulled up or pulled down in the LSI. However,because of preventing malfunction due to noise, etc., avoid using the “OPEN” condition whenever possible, and set to “H” level or “L”level. (3) Input video signals Input video signalsare target for analog signals (continuous signals). The input band of video signals is applicable up to the maximumof 10 MHz. (4) Bypass capacitor lfthe noise of alogicsystem is superposed on analog circuits such as the sample and hold circuits, analog characteristics (such as output voltage deviation and dynamic range,etc.) may deteriorate. Forthis reason, insert bypass capacits or of about 1 pF between VCC and GND. Fully evaluate and determine the value of bypass capacits orwith actually mounted on the LCD panel.
