Description
The Touchscreen TFT LCD model WF35QTIBCDBG0 is our 3.5 inch WF35L extended model TFT LCD display with SSD1963 controller board plus a 36 pin-out connector. This model is with Projected capacitive touch screen (PCAP), it's available in 8 bit or 16 bit option and already defined pin no. 33 ~ 36 as backlight supply on this SSD1963 LCD controller board, therefore, there is no need to design extra backlight circuit. The TFT Q Series Modules provide the following innovative advantages to offer outstanding performance for colorful displays:
- Q Series integrated a 36 pin-out connector on SSD1963 controller board and all connectors are the same direction.
- Q Series modules are available in 8 bit and 16 bit parallel interface options.
- The pin no. 33 ~ 36 already pre-defined as backlight supply.
- Built in backlight driver IC, Q series TFT displays can be drive by 5.0V (3.5" and 4.3" also support 3.3V). The customers do not have to change the backlight driver circuits while change the TFT module sizes.
- The 5.7", 7.0", 8.0"and 10.2" Q Series are allowed to design “Sleep Mode” to close BIAS(VGH, VGL, AVDD) low power consumption mode.
- Capacitive Touchscreen TFT options are available for all Q Series display, and the I2C read/write protocol can be input from 36pin connector.
