The in-cell touch display demo makes it easy for engineers to
experiment with the latest technologies for touch-sensitive
passive LCD.
The demo highlights the features of the NXP Chip-on-Glass (COG)
LCD driver PCF8576E and the capacitive sensor PCF8885. The
PCF8576E requires no external components to generate the drive
signals for the LCD, and supports up to four backplanes and
40 segment drivers. The PCF8885, which offers adjustable
response times and continuous auto-calibration, provides dynamic
touch sensing with eight sensor channels. Both devices use the
I²C bus for serial communications. The NXP technology allows
avoiding any interference between the LCD driving signals and the
cap sensor signals, thus enabling the in-cell touch technology with
no need for expensive and complicated solutions.
