Description

WF70A8SYAHMNN0 is a 7 inch MIPI DSI interface High Brightness 1024 x 600 IPS TFT-LCD module. This TFT-LCD is featured with IPS technology which is having the advantages of wider viewing angle of Left:85 / Right:85 / Up:85 / Down:85 degree (typical) and high brightness of 1100 nits (typical value). If customers don’t require high brightness, you can choose our WF70A8TYAHMNN0. This WF70A8 model is available in projected capacitive touch panel (PCAP) module number WF70A8SYAHMNGB and resistive touch screen option WF70A8SYAHMNT0.

WF70A8SYAHMNN0 module is built-in with EK7900 and EK7321 driver IC; it supports 4-Lanes MIPI interface (Mobile Industry Processor Interface) DSI (Display Serial Interface). The MIPI DSI interface becomes more popular because of the characteristics of High Speed Data Transmission and High Speed Clock Transmission. This TFT display module featured with anit-glare surface panel; aspect ratio 16:9, it can be operated at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃.
