LP116WH1

Liquid Crystal Display

Product Specification

1. General Description

The LP116WH1 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 10.1inches 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 determined with a 6-bit gray scale signal for each dot, thus, presenting a palette of more than 262,144 colors.

The LP116WH1 has been designed to apply the interface method that enables low power, high speed, low

EMI.

The LP116WH1 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 LP116WH1 characteristics provide an excellent flat display for office automation products such as Notebook PC.

2. The specified Icc current and power consumption are under the Vcc = 3.3V , 25℃, fv = 60Hz condition and Mosaic pattern.

3. The below figures are the measuring Vcc condition and the Vcc control block LGD used.

The Vcc condition is same as the minimum of T1 at Power on sequence.

4. This impedance value is needed for proper display and measured form LVDS 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).

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

9. 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.

10. 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.
