Description

The WF35QTIBCDBT0 is a 3.5-inch resistive touch screen TFT LCD display module with a resolution of 320x240 pixels and an aspect ratio of 4:3. This TFT module includes an SSD1963 controller board and a 36-pin connector on board. The model features an 8-bit or 16-bit option, with pins 33 to 36 already defined for backlight supply, eliminating the need for an extra backlight circuit. The module includes frame through holes for easy mounting and usage. This model uses an RTP resistive touch panel, and the 4-line signals (X1, Y1, X2, Y2) can be input through the 36-pin connector, reducing the difficulty for customers in wiring.

The operating temperature ranges from -20℃ to +70℃, and the storage temperature ranges from -30℃ to +80℃. The LCM power supply voltage is 3.0V to 3.3V, with a typical value of 3.1V. The brightness of the module is 300 nits, and the contrast ratio is 350:1 (typical value).
