The P12347-01CT can be used to adjust the display image quality, perform touchscreen on/off control, indicate incoming calls and also functions as an illuminance sensor; this feature enables image quality to be adjusted in fine detail. The proximity sensor also detects when a face draws near and automatically turns off the touchscreen function and LCD backlight.
The small package size of only 5.5×1.7×1.0mm enables the P12347-01CT to be incorporated into small electronic devices like smartphones and only requires a small supply voltage for operation, leading to very low current consumption.
