1.1 Scope:
LCD BM185WH2-T2BB
LM185WH2-T2BB is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)
backlight system. The matrix employs a-Si Thin Film Transistor as the active element. It is a transmissive type
display operating in the normally white mode. It has a 18.5 inch diagonally measured active display area with HD
resolution (768 vertical by 1366 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
a 8-bit gray scale signal for each dot, thus, presenting a palette of more than 16,7M colors with
Advanced-FRC(Frame Rate Control). It has been designed to apply the interface method that enables low power,
high speed, low EMI. FPD Link or compatible must be used as a LVDS(Low Voltage Differential Signaling) chip. It is
intended to support applications where thin thickness, wide viewing angle, low power are critical factors and graphic
displays are important. In combination with the vertical arrangement of the sub-pixels, the LM185WH2-T2BB
characteristics provide an excellent flat panel display for office automation products such as monitors
