The WF39QTIBSDBG0 is an extended model of the 3.9-inch WF39B Bar TFT-LCD display, integrated with an SSD1963 controller board and a 36-pin connector, part of the WINSTAR Q series Family. This model features a resolution of 480x128 pixels and a projected capacitive touch screen (PCAP). It supports an 8-bit/16-bit digital 8080-series MPU interface (MCU interface). The PCAP uses a CYTMA568 touch controller IC or its equivalent. Pins 33 to 36 are designated for the backlight power supply on the SSD1963 controller board, eliminating the need for an additional backlight circuit.
The WF39Q is a color TFT module with PCAP, offering a brightness of 400 nits and a contrast ratio of 500:1. It serves as an ideal upgrade from the monochrome STN WH1602L1 to a color TFT display with touch functionality, as both modules share a similar PCB outline of 122.0 x 44.0 mm.
