1 LHQ. ENEAL DESCIPTION The LHQ is a Color Active Matrix with Light Emission Diode(LED) backlight system. The matrix employs asi Thin Film Transistor as the active element. It is transmissive type display operating in the normally white mode. This TFTLCD has. inch diagonally measured active display area with (**) resolution. Each pixel is divided into ed, reen and lue subpixels or dots which are arranged in vertical stripes. lock Diagram Mipi D+ Mipi D Mipi CLK+ User Connector ( Pin) Mipi CLK DD(.), EE(.8), ND() ESET _SYNC TFTLCD Panel ( ) Driver IC ( Chip) LED_ANODE LED_CATHODE Fig. lock Diagram of TFTLCD Module with LED acklight Unit eneral Features Item Specification Active Screen Size Outline Dimension Pixel Pitch Pixel Format Color Depth Interface Power Consumption Luminance iewing Direction. diagonal.8 (H) x.
