WFN0286A2S0WADNA000 is a 2.86-inch bar type TFT LCD module with a resolution of 376x960 pixels. This color active matrix display uses amorphous silicon TFT as the switching device and has a 2.86-inch diagonally measured active area. The module is suitable for applications requiring a compact narrow-format display.
This module features a projected capacitive touch panel (PCAP) with optical bonding and supports 2-point touch. The touch panel uses an ST1633i driver IC or equivalent and supports the I2C interface. The optical bonding structure integrates the display and touch panel more closely.
The display adopts IPS technology and provides wide viewing angles of 85 degrees in all directions. It has a typical brightness of 900 cd/m². The module is driven by the ST7701P IC or equivalent and supports a 3-wire SPI + RGB 24-bit interface.
WFN0286A2S0WADNA000 is a normally black, transmissive TFT LCD module with a glare surface and an aspect ratio of 1:2.5. The operating temperature range is -30℃ to +85℃, and the storage temperature range is also -30℃ to +85℃. This module is suitable for applications requiring a compact bar type TFT display with projected capacitive touch.
Other options in this series include the high brightness version without touch, WFN0286A2S0WADNN000, and the standard brightness version without touch, WFN0286A2T0WADNN000, allowing you to choose the most suitable model based on different application requirements.
