Product Specification
1. General Description
The LP156WF1 is a Color Active Matrix Liquid Crystal Displa y with an integral Light Emitting Diode (LED) backlight system. The matrix employs a-Si Thin Film Transistor as the active ele ment. 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 horizon tal 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 dete rmined w ith a 6-bi t gray s cale s ignal for each dot, thus, presenting a palette of more than 262,144 colors.
The LP156WF1 has been designed to apply the interface method that enables low power, high speed, low EMI.
The LP156WF1 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 LP156WF1 characteristics provide an excellent flat display for office automation p roducts such as Notebook PC.

3. Electrical Specifications 3-1. Electrical Characteristics
The LP156WF1 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. This impedance value is needed to proper display and measured form LVDS Tx to the mating connector.
3. The specified LED current and power consumption are under the Vled = 12.0V , 25℃, Dimming of Max
luminance whereas White pattern is displayed and fv is the frame frequency.
4. The operation of LED Driver below minimum dimming ratio may cause flickering or reliability issue.
5. 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.
6. The life time is determined as the sum of the continuous operation time at which brightness of LCD at the typical LED current is 50% compare to that of minimum value specified in table 9 under general user condition.
