WF70A8TYAHLNN0 is a landscape 7-inch IPS TFT module with a resolution of 1024x600 pixels. The WF70A8 model is built in with ST5021 and ST5651 driver ICs, supports an LVDS interface, and has a contrast ratio of 800:1 (typical value), brightness of 600 cd/m² (typical value), aspect ratio of 16:9, an anti-glare surface glass, and a normally black, transmissive LCD type.
The IPS (In-Plane Switching) technology offers superior color reproduction and better viewing angles compared to traditional TN (Twisted Nematic) displays. It provides vibrant, consistent colors and sharp image clarity from nearly any viewing angle, making it ideal for applications requiring precise and accurate visual output. The viewing angle of this 7" IPS TFT is Left:85 / Right:85 / Up:85 / Down:85 degrees (typical value), ensuring that the display remains clear and readable from different perspectives.
The LVDS interface is widely used in TFT displays requiring high-speed data transmission. It offers a high data rate with low power consumption, better noise immunity, and reliable signal transmission, making it ideal for stable and efficient performance in industrial and commercial applications.
The supply voltage (VDD) of WF70A8TYAHLNN0 ranges from 3.0V to 3.6V, with a typical value of 3.3V. It operates in temperatures from -20℃ to +70℃ and can be stored in temperatures from -30℃ to +80℃. We also offer Resistive Touch Panel (RTP) and Projected Capacitive Touch Panel (PCAP) options for the WF70A8 model.
