4-2. Backlight driving
CN3 (Inverter control)
*0 : Low level voltage(0V)
*For overlapping temperatures (such as 5℃,10℃,15℃,20℃,25℃, 30℃,35℃) select the optimum parameter,
【Note 1】 V
【Note 2】 V
Measuring the correlation between detected temperature by the sensor on PWB in users side and actual surface
temperature of panel at center , convert the temperature detected by the sensor to the surface temperature of
panel to enter the 3 bit temperature data.
judging from the actual picture image.
Pin no.
According as the surface temperature of the panel, enter the optimum 3 bit signal into pin No.4,5,6.
*Shield case on the back surface of module doesn't contact to GND of internal circuit．
Pin No.
