LP097X02
Liquid Crystal Display
Product Specification
1. General Description
The LP097X02 is a Color Active Matrix Liquid Crystal Display with an integral 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 Black mode. This TFT-LCD has 9.7 inches diagonally measured active display area with XGA
resolution(1024 horizontal by 768 vertical pixel array). Each pixel is divided into Red, Green and Blue subpixels 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 more than 262,144 colors.
The LP097X02 has been designed to apply the interface method that enables low power, high speed, low EMI.
The LP097X02 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 LP097X02
characteristics provide an excellent flat display for office automation products such as Notebook PC.

Note)
1. The specified current and power consumption are under the Vcc = 3.3V , 25℃, fv = 60Hz condition
whereas Mosaic pattern is displayed and fv is the frame frequency.
2. This impedance value is needed to proper display and measured form LVDS Tx to the mating connector.
3. LED input voltage must be input below than 12V to operate normally for LED Driver.
4. The typical operating current is for the typical surface luminance (LWH) in optical characteristics.
5. The LED power consumption shown above does not include power of external LED driver circuit
for typical current condition.
6. The life time is determined as the time at which brightness of lamp is 50% compare to that of initial value
at the typical lamp current.
