LP156WH2
Liquid Crystal Display
Product Specification
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.

1. The measuring position is the connector of LCM and the test conditions are under 25, fv = 60Hz,
Black pattern.
2. The specified Icc current and power consumption are under
the Vcc = 3.3V , 25, fv = 60Hz condition and Mosaic pattern.
3. This Spec. is the max load condition for the cable impedance designing.
4. The below figures are the measuring Vcc condition and the Vcc control block LGD used.
The Vcc condition is same the minimum of T1 at Power on sequence.

6. The measuring position is the connector of LCM and the test conditions are under 25.
7. The current and power consumption with LED Driver are under the Vled = 12.0V , 25, Dimming of

9. In case of duty ratio 1% ~ 5%, there is no functional problem but Flicker can be seen.
10. If Jitter of PWM is bigger than maximum. It may cause flickering.
11. 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.
12. The life time is determined as the time at which brightness of LED is 50% compare to that of minimum
value specified in table 9.
