3.2.1 Power circuit 

The input power of controller board is 18V. The power circuit uses voltage 
regulators to provide15V, 5V and 3.3V for other components. The 13.5V is got 
from 15V after the voltage drop of two diodes – 1N4148 . The LED backlight 
require a 13.6V--19mA power source. Constant current will keep constant 
lightness. The adjustable regulator – LD1117 can fulfil this requirement and 
another NPN transistor – 2N3904 are used to switch ON/OFF the backlight. 

3.2.2 CPU and serial EPROM 

This controller board uses a 80-series CPU with 4KB on-chip FLASH EPROM 
to do central control -- including initial setting of LCD driver IC, LED backlight 
control, button-pushed sensing and communication with main board. The 
serial EPROM stores setting data of LCD which is got from the calibration 
process. CPU will read the serial EPROM and complete the initial setting for 
LCD after power on.
