WF28JSYAJDNN0 is a 2.8-inch IPS TFT LCD module with a wider viewing angle and a resolution of 240x320 pixels. The WF28J module is designed in portrait mode as an IPS TFT-LCD, incorporating the ILI9341 controller IC. It supports MCU 8-bit/16-bit or SPI interfaces, providing a contrast ratio of 800:1 (typical value). WF28JSYAJDNN0 is a high-brightness version with a brightness of 1000 nits (typical value).
The supply voltage for the interface logic (IOVCC) of the WF28JSYAJDNN0 model ranges from 1.65V to 3.3V, while the supply for the analog circuit is from 2.5V to 3.3V. It is a normally black, transmissive LCD type with an aspect ratio of 3:4 and a glare surface glass. The operating temperature ranges from -20°C to +70°C, and storage temperatures range from -30°C to +80°C.
This 2.8-inch IPS TFT provides a wider viewing angle than TN TFT, with angles 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.
