Description

WF70A2SIAGDNGA is a high-brightness TFT LCD module with a projected capacitive touch panel (PCAP), featuring a resolution of WVGA 800x480 pixels and a diagonal size of 7 inches. This TFT model is equipped with the ST-5623 and ST-5091 driver ICs, offering a high brightness of 700 nits (typical value). The WF70A2 TFT model supports an RGB interface, and the PCAP touch screen IC is the ILI2130, which supports an I2C interface and 5-point touch.

The supply voltage for logic (VCC) of the WF70A2SIAGDNGA ranges from 3.0V to 3.6V, with a typical value of 3.3V. It features a glare surface panel, a viewing direction of 12 o'clock, gray scale inversion at 6 o'clock, and an aspect ratio of 16:9. The contrast ratio is 800:1 (typical value). It operates at temperatures from -20℃ to +70℃ and has a storage temperature range from -30℃ to +80℃. The WF70A2SIAGDNGA is highly suitable for outdoor applications, such as outdoor measuring equipment and GPS navigation systems.
