LP154WP4

Liquid Crystal Display

Product Specification

1. General Description

The LP154WP4 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 15.4 inches diagonally measured active display area with WXGA+ resolution(1440 horizontal by 900 vertical 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 determined with a 6-bit gray scale signal for each dot, thus, presenting a palette of more than 262,144 colors.

The LP154WP4 has been designed to apply the interface method that enables low power, high speed, low EMI.

The LP154WP4 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 LP154WP4 characteristics provide an excellent flat display for office automation products such as Notebook PC.

Note)

1. The specified 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 inrush current is measured under a maximum or minimum Vcc in black pattern.

4. The typical operating current is for the typical surface luminance (LWH) in optical characteristics.

I

is the current of each LEDs’ string, LED backlight has 6 strings on it.

5. The LED power consumption shown above does not include power of external LED driver circuit for typical current condition.

6. The life time is determined as the time at which brightness of LED is 50% compare to that of initial value at the typical LED current.
