LP133WH2

Liquid Crystal Display

Product Specification

1. General Description

The LP133WH2 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 13.3 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
determined with a 6-bit gray scale signal for each dot, thus, presenting a palette of more than 262,144
colors.
The LP133WH2 has been designed to apply the interface method that enables low power, high speed, low
EMI.
The LP133WH2 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
LP133WH2 characteristics provide an excellent flat display for office automation products such as Notebook
PC.

3. Electrical Specifications
3-1. Electrical Characteristics

The LP33WH2 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.

Note)

1. 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.

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 flikering or relaibility 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 time at which brightness of LCD is 50% compare to that of minimum

value at Table 7. These LED backlight has 6 strings on it and the typical current of LED’s
string is base on Table 2.
