Description

MAXEN MX-H121HL20-IW01 is a color active matrix thin film transistor (TFT) liquid crystal display (LCD) that uses amorphous silicon TFT as a switching device. The 12.1 inch LCD Screen model is composed of a TFT LCD panel, a driving circuit and a backlight system. This TFT LCD has a 12.1 inch diagonally measured active display area with XGA (1024 horizontal by 768 vertical pixel) resolution and it supports LVDS interface. MX-H121HL20-IW01 is adopted IPS panel which is having the advantage of wider view angle of 85/85/85/85, contrast ratio 900:1 (typical value), brightness 600 nits (typical value), anti-glare surface panel, aspect ratio 4:3. MX-H121HL20-IW01 model is also available in projected capacitive touch screen (PCAP) and resistive touch screen (RTP).

The supply voltage(VDD) of MX-H121HL20-IW01 is from 3.0V to 3.6V, the typical value of 3.3V. It can be operating at temperatures from -30℃ to+ 80℃ and storage temperatures from -30℃ to +80℃. It is a wide temperature LCD Screen which is suitable for use in industrial and extreme environments.
