1, General description
L2M18 is a control board of Color Active Matrix Liquid Crystal Display, It is designed to be applied to LVDS Low Voltage Differential Signaling as the interface method to enable a simple and low-cost implementation in both board and panel.
L2M18 is intended to support YPbPr&HDMI input and up to 1920x1080 FHD panel.
L2M18 also provides other very important functions, It supports PAL or SECAM color TV system for Europe, Moreover. it can achieve Analog RGB input signal up to SXGA 1024 vertical /1280 horizontal pixel resolution. it also supports DVD(Option)/YPbPr /HDMI input.
L2M18 includes an audio amplifier which can support 2×3W(or 2x5W) audio power output. it supports NICAM/A2 stereo input and selects audio channels according to the input signal detection. OSD pictures are smooth and manual operating is very simple.
