LM200WD1
Liquid Crystal Display
Product Specification
1. General description
LM200WD1-TLD2 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. It is a transmissive type display operating in the normally white mode. It has a
20.0 inch diagonally measured active display area with HD+ resolution (900 vertical by 1600
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 LM200WD1-TLD2 characteristics
provide an excellent flat panel display for office automation products such as monitors.

3. Electrical specifications
3-1. Electrical characteristics
It requires two power inputs. One is employed to power the LCD electronics and to drive the
TFT array and liquid crystal. The second input power for the CCFL/Backlight, is typically
generated by an inverter. The inverter is an external unit to the LCDs.
