LP150U1
Liquid Crystal Display
Product Specification
1. General Description
The LP150U1-A2 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) back light 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. This TFT-LCD has a 15.0 inch diagonally
measured active display area with UXGA resolution(1200 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 6-bit gray scale signal for each dot, thus, presenting a
palette of 262,144 colors.
The LP150U1-A2 has been designed to apply the interface method that enables low power, high speed low
EMI. Flat Link must be used as a LVDS(Low Voltage Differential Signaling) chip.
The LP150U1-A2 is intended to support applications where thin thickness, low power are critical factors and
graphic displays are important. In combination with the vertical arrangement of the sub-pixels, the LP150U1-A2
characteristics provide an excellent flat panel display for office automation products such as Notebook PC.

2. Electrical Specifications
2-1. Electrical Characteristics
The LP150U1-A2 requires two power inputs. One is employed to power the LCD electronics and to drive the
TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an inverter.
The inverter is an external unit to the LCD.
