Description
WF39DTLFSDHG0 is a 3.9-inch bar-shaped HDMI TFT display. It features a projected capacitive touch panel (PCAP) with 5-point multi-touch. The built-in GT911 IC of the PCAP comes with USB interfaces. The module boasts a resolution of 480x128 pixels, a brightness of 400 cd/m2, a contrast ratio of 500:1, 6 o'clock viewing direction (looking up), 12 o'clock grayscale reversed direction, and a glare glass surface. WF39DTLFSDHG0 adopts TFP401 controller IC, supporting HDMI interfaces (DVI signal) compatible with Raspberry Pi.
The power supply voltage of the module is set as 5V (typical value), its operation temperature range is from -20°C to +70°C, and its storage temperature range covers from -30°C to +80°C. This HDMI TFT LCD is suitable for applications in electronic devices, catering equipment, medical measuring instruments, etc.
