1. General Description
The LP156WH2 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. This TFT-LCD has 15.6 inches 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 6-bit gray scale signal for each dot, thus, presenting a palette of
more than 262,144 colors. The LP156WH2 has been designed to apply the interface method that enables
low power, high speed, low EMI. The LP156WH2 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 LP156WH2 characteristics provide an excellent flat display for office
automation products such as Notebook PC.

3. Electrical Specifications
3-1. Electrical Characteristics
The LP156WH2 requires two power inputs. The first logic is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. The second backlight is the input about LED BL.with LED Driver.

8. The operation of LED Driver below minimum dimming ratio may cause flickering or reliability issue.
9. If Jitter of PWM is bigger than maximum. It may cause flickering.
10. This Spec. is not effective at 100% dimming ratio as an exception because it has DC level equivalent
to 0Hz. In spite of acceptable range as defined, the PWM Frequency should be fixed and stable for
more consistent brightness control at any specific level desired.
11. The life time is determined as the time at which the typical brightness of LCD is 50% compare to that of
initial value at the typical LED current. These LED backlight has 4 strings on it and the typical current
of LED’s string is base on 21mA.
