2. To stabilize the supply voltage, please be sure to insert a 0.1 F bypass capacitor between

converter, insertion of a bypass capacitor of about 0.01 F is also advised between the -

driver IC's temperature for the Junction Temperature. So, it should be considered to use the
suitable mechanical design for the heat spreading and use the LPC function and the output
reset function for the power reduction. Especially, it is recommended to measure the
temperature of the driver IC surface.

Input the -corrected power supplies from outside by using operational amplifier.
Make sure to maintain the following relationships. During the gray scale voltage
output, be sure to keep the gray scale level power supply at a constant level.
