Liquid Crystal Display

Product Specification

1. General Description

The LP156WF6 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 FHD
resolution (1920 horizontal by 1080 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 LP156WF6 has been designed to apply the interface method that enables low power, high
speed, low EMI. The LP156WF6 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 sub­pixels, the LP156WF6 characteristics provide an excellent flat display for office automation products such as
Notebook PC.

4. The operation of LED Driver below minimum dimming ratio may cause flickering or reliability issue.

5. If Jitter of PWM is bigger than maximum, it may induce flickering.

6. 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.

7. 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.

Note)

1. HPD IRQ : Sink device wants to notify the Source device that Sink’s status has changed so it toggles HPD line,
forcing the Source device to read its Link / Sink Receiver DPCD field via the AUX-CH

2. HPD Unplug : The Sink device is no longer attached to the Source device and the Source device may then disable its
Main Link as a power saving mode

3. Plug / Re-plug : The Sink device is now attached to the Source device, forcing the Source device to read its Receiver
capabilities and Link / Sink status Receiver DPCD fields via the AUX-CH
