Description

WF35LTZACDNN0 is a 3.5-inch Thin Film Transistor (TFT) LCD module with wide viewing angles. It features a resolution of 320 x 240 dots and a 4:3 aspect ratio. This TFT display incorporates O-Film technology to broaden its viewing angles. The module’s dimensions are 76.84 × 63.84 mm, with an active area size of 70.08 × 52.56 mm. The WF35LTZACDNN0 TFT display utilizes the HX8238 driver IC, supporting 24-bit RGB interfaces. It comes with an anti-glare surface.

While TN-LCD panels dominate the market in most industrial applications, TN technology suffers from a phenomenon called gray scale inversion. This means that on one viewing side, the color of the image suddenly changes after exceeding a specified viewing angle. Consequently, the standard TFT models we offer have limited viewing angles. Winstar offers an O-Film TFT solution to enhance TN glass viewing angles and overcome gray scale inversion.

This module is characterized by a brightness of 300 cd/m² (typical value) and a contrast ratio (typical value) of 350:1. The supply voltage ranges for LCM from 3.3V to 3.0V, with a typical value of 3.3V. It can operate at temperatures ranging from -20°C to +70°C, with storage temperatures ranging from -30°C to +80°C.
