The WF43VSZAEDNGA is a 4.3-inch TFT LCD module with Projected Capacitive Touch Panel (PCAP) designed for industrial applications, offering high brightness of 600 cd/m² and a resolution of 480x272 pixels. This module incorporates O-Film technology, providing wide viewing angles, making it ideal for use in environments where visibility is crucial.
Built-in with the ST7282-G4-1L driver IC, the WF43VSZAEDNGA 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. The Projected Capacitive Touch Panel (PCAP) is equipped with an ILI2130 driver IC, supporting an I2C interface and providing 5-point touch functionality.
Currently, TFT displays with wide viewing angles 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, impacting image clarity. The O-Film TFT module used in the WF43VSZAEDNGA 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.
