HLR-1920 LCD Controller

The HLR-1920 LCD controller is an enhanced version of the ALR-1920 to make it more suitable for use in harsher environments re temperature, humidity and vibration. Higher temperature rated components, conformal coating and connector changes are amongst the modifications.

The HLR-1920 combines three of the most popular input formats, HDMI, Analog RGB (VGA) and DisplayPort in a compact general purpose solution for LCD panels up to 1920x1200 resolution. One of the key features of this highly reliable controller is the low signal latency from input signal to panel output signal.
