The WF39ESWASDNG0 is a high brightness 3.9-inch Bar Type IPS TFT-LCD display with a resolution of 480x128 pixels, featuring a Projected Capacitive Touch Panel (PCAP). This module is equipped with the SC7283 driver IC and supports a 24-bit RGB interface. The touch panel is built with a GT911 IC and supports I2C interface with 5-point touch functionality.
The WF39ESWASDNG0 uses an IPS panel, offering the advantage of a wider viewing angle (Left: 80 / Right: 80 / Up: 80 / Down: 80 degrees, typical), a contrast ratio of 800:1 (typical value), and high brightness of 800 nits (typical value). The supply voltage for the LCM is between 3V and 3.6V. It is a wide temperature range TFT module, operating from -30°C to +85°C, with storage temperatures ranging from -30°C to +85°C.
This panorama widescreen 3.9-inch WF39E Bar TFT-LCD display offers high-quality, colorful images. It is especially suitable for server systems, audio equipment, advertising displays, automotive/aviation/marine equipment, security systems, industrial equipment, outdoor intercom systems and control panels, medical devices, and drone controls.
The WF39E series also offers a Resistive Touch Panel (RTP) option. For more details, please visit the WF39ESWASDNT0 product page on our website. If a touch panel is not needed, customers can opt for the WF39ESWASDNN0 (high brightness version) or the WF39ETWASDNN0 (standard brightness version) module.
