LP156WF2
Liquid Crystal Display
Product Specification
1. General Description
The LP156WF2 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(1080 vertical by 1920 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 LP156WF2 has been designed to apply the interface method that enables low power, high speed, low
EMI.
The LP156WF2 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
LP156WF2 characteristics provide an excellent flat display for office automation products such as Notebook
PC.

3-1. Electrical Characteristics
The LP156WF2 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.

1. The measuring position is the connector of LCM and the test conditions are under 25℃, fv = 60Hz.
2. The specified Icc current and power consumption are under the Vcc = 3.3V , 25℃, fv = 60Hz condition.
whereas Mosaic Pattern is displayed andd fv is the frame frequency

4. This impedance value is needed for proper display and measured from eDP Tx to the mating connector.
5. The measuring position is the connector of LCM and the test conditions are under 25℃.
6. The current and power consumption with LED Driver are under the Vled = 12.0V , 25℃, Dimming of
Max luminance and White pattern with the normal frame frequency operated(60Hz).
7. The below figures are the measuring Vled condition
and the Vled control block LGD used.
VLED control block is same with Vcc control block.
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 induce 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 brightness of LCD is 50% compare to that of minimum
value specified in table 7. under general user condition.
