For TFT products, there is an increasing demand for wide viewing angle functionality. Winstar introduces the TFT O-Film product series to meet customers’ application requirements in the industrial field. Currently, TFT displays with wide viewing angle functionality in the market include MVA (Multi-domain Vertical Alignment), IPS (In-Plane Switching), and O-Film TFT technologies. Compared to MVA and IPS TFT, O-Film TFT offers competitive pricing for wide viewing angle TFT products, making it one of the best choices for industrial applications.
Most of the TFT-LCD glass used in industrial applications is TN-LCD. However, TN-LCD has a significant grayscale inversion phenomenon, where lower grayscales may appear brighter than higher ones at certain wide angles. The O-Film TFT module products introduced by Winstar can increase the viewing angle and improve the grayscale inversion phenomenon, making them ideal for industrial applications.
WF43VTZAEDNN0 is a 4.3-inch O-Film TFT Panel LCD Module with a resolution of 480 x 272 pixels and a 16:9 aspect ratio. It utilizes O-Film technology for wider viewing angles and overcoming grayscale inversion. The display employs the ST7282 driver IC, supporting 24-bit RGB interfaces and featuring an anti-glare surface.
This module has a typical brightness of 400 cd/m² and a contrast ratio of 500:1. The supply voltage ranges from 3.1V to 3.5V, with a typical value of 3.3V. It can operate at temperatures from -20°C to +70°C, with storage temperatures ranging from -30°C to +80°C.
