Description
WF28JTYAJDNF0 is a 2.8-inch portrait-mode TFT display module with a resolution of 240x320 pixels, a brightness of 400 cd/m2, and a contrast ratio of 800:1. This LCD module features a projected capacitive touch panel and is equipped with the ILI9341V IC, supporting MCU or SPI interfaces. The module has dimensions of 50.5 x 69.7 mm, with an active area of 43.2 x 57.6 mm. The supply voltage ranges from 1.65V to 3.3V. The projected capacitive touch panel is integrated with the FT6336G IC, supporting the I2C interface and a single detect point. The module can operate within a temperature range of -20°C to +70°C, with storage temperatures ranging from -30°C to +80°C.
WF28JTYAJDNF0 utilizes IPS technology, providing a wide viewing angle of Left: 80 / Right: 80 / Up: 80 / Down: 80 degrees (typical value). IPS panels in TFT displays offer broader viewing angles, accurate and consistent color reproduction, superior image quality, precise touchscreen performance, and consistent color temperature. The versatility of IPS TFT-LCD displays makes them suitable for various applications, including consumer electronics, medical displays, and industrial control panels.
