Product Specification
1. General Description
The LP133WH1 is a Color Active Matrix Liquid C rystal Disp lay with an integra l LED backlight system. The matrix employs a-Si Thin Film Tran s istor as the active element. It is a trans missi ve type d isplay operating in the normally white mode. This TFT-LCD has 13.3 inches diagonally measured active display area with WHD resolution(1366 horizontal by 768 ver tical pixe l ar ray). Each pixel is divided into Red, Green and Blue sub-pixels or dots which are a rranged in vertica l stripes. Gra y 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 LP133WH1 has been designed to apply the in terface method that enables low power, high speed, low EMI.
The LP133WH1 is intended to support applications where thin th ickness, low power are critica l factor s and graphic displays are important. In combination with the vertical arrangement of the sub-pixels, the LP133WH1 characteristics provide an excellen t fla t display for office automation products such as Notebook PC.

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. There may be a flickering or some reliability issues when LED driver is operated by under condition of minimum.
5. The PWM Frequency has 0Hz, DC level for dimming ratio 100%. The PWM Frequency should be fixed and continue for stable luminance levels what you want.
6. The life time is determined as the time at which brightness of LCD is 50% compare to that of initial value at the typical LED current. These LED backlight has 6 strings on it and the typical current of LED’s string is base on 20mA.
