The WF70A8TYAHLNGC is a 7-inch TFT LCD module with a resolution of 1024 × 600 pixels and an aspect ratio of 16:9. This TFT module is equipped with a projected capacitive touch screen and adopts IPS display technology, providing wider viewing angles of 85 degrees in all directions (left, right, up, and down). It features built-in ST5021 and ST5651 driver ICs and supports an LVDS interface. The LVDS interface is becoming increasingly popular for TFT displays requiring high-speed data transmission. It provides a high data transmission rate with low power consumption, offering advantages such as compatibility with lower voltage power supply and noise, higher noise suppression ability, and more reliable signal transmission.
The module's dimensions are 202 × 135.5 mm, with an active area size of 154.2144 × 85.92 mm. It includes a projected capacitive touch panel (PCAP) with a GT911 driver IC, supporting I2C interface and 5-point touch functionality. The power supply voltage ranges from 3.0V to 3.6V, with a typical value of 3.3V.
The operating temperature of the module ranges from -20℃ to +70℃, and the storage temperature range covers from -30℃ to +80℃. It has a contrast ratio of 800:1 (typical value) and a brightness of 450 nits (typical value).
The 7-inch display module is suitable for use in control panels for testing equipment, industrial control systems, audio equipment, and smart home control systems. Compared to the WF70A8TYAHLNGB model, the WF70A8TYAHLNGC has a larger cover glass (CG), offering easier installation flexibility for various applications.
