WF28JTYAJDNG0 is a 2.8-inch TFT LCD module with a resolution of 240x320 pixels and a 3:4 aspect ratio. This module is designed for portrait mode and features IPS technology with a wide viewing angle of 80/80/80/80 (typical). It has a typical brightness of 400 cd/m² and contrast ratio of 800:1.
The display is integrated with an ILI9341V or equivalent controller IC and supports MCU and SPI interfaces. The module outline dimensions are 50.5 x 69.7 mm, with an active area of 43.2 x 57.6 mm. The panel structure is TFT, Normally Black, Transmissive.
WF28JTYAJDNG0 includes a projected capacitive touch panel (CTP) with I2C interface and 1-point touch support. The touch panel uses a CF1124 or equivalent IC. For power supply, the digital voltage (IOVCC) ranges from 1.65V to 3.3V, the analog voltage (VCI) ranges from 2.5V to 3.3V, and the touch logic supply (VDDT) is 3.0V to 3.6V.
This module operates within a temperature range of -20°C to +70°C, with a storage temperature range of -30°C to +80°C. It is suitable for industrial control panels, portable devices, and medical equipment.
