WF0299ATYAC2MNR0 is a portrait mode 2.99-inch stretched bar type TFT LCD with a resolution of 268×800 pixels and an On-Cell touch panel (capacitive touch). On-Cell technology involves embedding the touch sensor into the LCD module, either on the color filter substrate or between the polarizers. One of the main advantages of On-Cell touch technology is the reduced thickness, as the touch layer is directly integrated into the display panel, eliminating the need for an additional touch layer and thereby reducing the overall thickness of the display.
The module comes with an On-Cell capacitive touch screen with a CST328 driver IC, supporting I2C interface and 2-point touch functionality. This integration enhances the user experience by enabling precise and responsive touch input, while the I2C interface facilitates easy communication with the device’s control system.
This On-Cell touch TFT display uses IPS technology, providing wider viewing angles of 80 degrees to the left, right, up, and down. It has a typical brightness of 530 nits and a contrast ratio of 1200:1. The TFT module integrates the GC9503 driver IC, which supports the MIPI DSI serial interface (2 lanes). The MIPI DSI interface offers advantages such as low power consumption, high transmission rates, support for multiple data-encoding formats, and reduced noise and interference.
The module operates in temperatures ranging from -20℃ to +70℃, and can be stored in temperatures from -30℃ to +80℃. This bar type TFT module is ideal for use in electronic door locks, massage chair control panels, and other devices that require a stretched display screen.
