Description
The model no. WF35QTIBCDBT0 is Winstar WF35Q module with Resistive Touch Screen TFT. It supports 8 bit or 16 bit option and pre-defined pin no. 33 ~ 36 as backlight supply; therefore, the customers 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.
- Resistive Touch Screen options are available for all Q Series TFT display, and 4-Line signal (X1, Y1, X2, Y2) can be input from 36pin connector.
