LP156WH2
Liquid Crystal Display
Product Specification
1. General Description
The LP156WH2 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 white mode. This TFT-LCD has 15.6 inches diagonally measured active display area with HD
resolution (1366 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 de
termined 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 LP1
56WH2 characteristics provide an excellent flat display for office automation products such as Notebook PC
.

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.

2. The specified Icc 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.
(Max current pattern is Black, measured by Multi-Meter=EVEN)
3. This Spec. is the max load condition for the cable impedance designing. (Measured by Multi-Meter = EVEN)

9. The operation of LED Driver below minimum dimming ratio may cause flickering or reliability issue.
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 7. under general user condition.
