The WF43VSZAEDNN0 is a 4.3-inch TFT LCD module designed for industrial applications, offering high brightness of 800 cd/m² and a resolution of 480x272 pixels. This module incorporates O-Film technology, providing wide viewing angles and an anti-glare surface, making it ideal for use in environments where visibility is crucial.
Built-in with the ST7282 driver IC, the WF43VSZAEDNN0 supports 24-bit RGB interfaces, ensuring compatibility with a variety of systems. It operates at a supply voltage for logic (VCC) ranging from 3.1V to 3.5V, with a typical value of 3.3V, and supports a 16:9 aspect ratio for optimized display content.
The module is designed to withstand operating temperatures from -20℃ to +70℃, and storage temperatures from -30℃ to +80℃, offering reliable performance in a wide range of industrial environments.
Currently, TFT displays with wide viewing angle functionality include MVA (Multi-domain Vertical Alignment), IPS (In-Plane Switching), and O-Film technologies. Compared to MVA and IPS, O-Film TFT offers a more cost-effective solution for achieving wide viewing angles, making it one of the best choices for industrial applications.
Most industrial TFT-LCD modules use TN-LCD panels, which suffer from significant grayscale inversion at wide angles. In these panels, lower grayscales can appear brighter than higher ones, affecting image clarity. The O-Film TFT module used in the WF43VSZAEDNN0 addresses this issue by enhancing the viewing angle and improving grayscale consistency, making it ideal for industrial applications where display clarity and visibility are paramount.
The WF43VSZAEDNN0 serves as an alternative to the WF43HSZAEDNNB, which used the CPT (Chunghwa Picture Tubes Ltd) EOL TFT panel. With O-Film technology and improved viewing angles, the WF43VSZAEDNN0 ensures superior performance and is a reliable solution for new industrial designs.
