What is tft capacitive touchscreen:

TFT capacitive touch screen means the tft lcd screen attached with projected capacitive touch screen. we also call it tft with CTP or TFT with PCAP, the projected capacitive touch panel can be stuck on the tft lcd screen with optical bonding and frame bonding. to the TN tft lcd display, the capacitive touch attached way would be frame bonding, if for IPS TFT lcd screen, the PCAP can be attached by optical bonding way, the optical bonding capacitive touch can be higher transparencty ratio and less light scattering than frame bonding capacitive touch panel.

The projected capacitive touch screen can be in USB interface and I2C interface, it is easy to connect to the LCD controller board.
