Description
Winstar's O Film TFT technology is tailored to meet the demands of applications requiring wider viewing angles and superior performance.
Traditionally, industrial TFT-LCD glasses have relied on TN-LCD technology, which unfortunately suffers from gray scale inversion, limiting the viewing angles of standard TFT models. However, Winstar addresses this issue with our TFT O-Film solution, providing a cost-effective alternative to technologies like MVA or IPS.
Our WF43VTZAEDNGA model exemplifies this advancement, featuring a standard 4.3-inch O Film TFT LCD Capacitive Touchscreen Display with a resolution of 480 x 272 pixels and a 16:9 aspect ratio.
Utilizing O-Film technology, this display offers wider viewing angles while effectively overcoming gray scale inversion, enhancing the overall viewing experience. The integration of the ST7282 driver IC supports 24-bit RGB interfaces and features a glare surface.
The module comes with a projected capacitive touch panel (PCAP) with ILI2130 driver IC, supporting I2C interfaces and a 5-point touch function, allowing for intuitive interaction with your applications.
With a typical brightness of 300 cd/m² and a contrast ratio of 500:1, this display ensures crisp and vivid imagery. Operating within a voltage range of 3.1V to 3.5V, with typical values of 3.3V, it offers efficient power consumption. This module can operate at temperatures ranging from -20°C to +70°C, with storage temperatures from -30°C to +80°C, ensuring reliability and durability.
