WF24LTYAJMNG0 is a 2.4-inch IPS TFT-LCD display module with a projected capacitive touch panel and a resolution of 240 x 320 (RGB) dots. The module is equipped with the ST7785MA driver IC, supporting a 1-lane MIPI interface. While it primarily uses a 1-lane MIPI interface for the TFT, there's also an option to support MCU or SPI interfaces.
The IPS panel provides wider viewing angles, with typical values of 80° (left), 80° (right), 80° (up), and 80° (down). IPS technology offers faster response times, higher transmittance, improved color performance, and precise imaging, making it ideal for applications requiring superior visual quality.
The projected capacitive touch panel of the WF24LTYAJMNG0 incorporates the CF1124 IC, supporting an I2C interface and a 1-point touch function.
This 2.4-inch TFT-LCD operates in portrait mode, featuring a contrast ratio of 800:1 (typ.) and a brightness of 400 nits (typ.). It is designed to function within a temperature range of -20°C to +70°C, with storage temperatures from -30°C to +80°C.
The versatile display is suitable for a wide range of applications, including air quality testing, blood glucose measurement, MP3 players, and home appliances. It is also well-suited for specialized applications such as speedometers, safety monitoring systems, handheld devices, and dash cameras in compact industrial equipment.
