A-2: OP 1500 LCD
The standard display used for the OP 1500 is either an LG.Phillips LM150X08-TL03 or an AUO
M150XN07 or its equivalent. LM150X08-TL03 is a color active matrix liquid crystal display with an
integral cold cathode fluorescent lamp (CCFL) backlight system. The matrix employs a-Si thin film
transistor as the active element.
A-2-1: 15” LG.Phillips LM150X08-TL03
It is a transmissive type display operating in the normally white mode. It has a 15” diagonally
measured active display area with XGA resolution (768 vertical by 1024 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the brightness of the sub-pixel color is determined with an 8-bit gray scale signal for
each dot, thus, presenting a palette of more than 16M colors. It has been designed to apply the 8-bit
1 port LVDS interface.
