10. SUPPLY VOLTAGE SEQUENCE
(1) Supply voltage sequence and backlight control sequence
Note1:
Remark1: Logic signals (synchronous signals and control signals) should be "0" voltage (V), when VDD is
Remark2: When the power supply voltage (VDD) fluctuates less than 4V, the LCD module may not be
Remark3: Turn on the backlight should be controlled while logic signals are supplied. The backlight power
Remark4: 12V for backlight should be started up within 800ms, otherwise, the protection circuit makes the
Remark5: The backlight is turned off with safety circuit, when “L” period of BRTP signal is input more than
Remark6: Do not input “H” PWSEL, when VDDB is 0V or BRTC is “L”.
