Liquid Crystal Display

Product Specification

1. General Description

The LM151X4-A3 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) 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 a 15.1 inchs diagonally
measured active display area with XGA resolution(768 vertical by 1024 horizontal 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 LM151X4-A3 has been designed to apply the TTL interface method.
The LM151X4-A3 LCD is intended to support applications where high brightness, wide viewing angle, high
color saturation, and high color depth are very important. In combination with the vertical arrangement of
the sub-pixels, the LM151X4-A3 characteristics provide an excellent flat panel display for office automation
products such as monitors.

3. Electrical Specifications
3-1. Electrical Characteristics

The LM151X4-A3 requires two power inputs. One is employed to power the LCD electronics and to drive the
TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an inverter.
The inverter is an external unit to the LCD.

Notes: 1. The specified current and power consumption are under the Vcc = 3.3V , 25 , fv =
60Hz condition Power supply input current and Typ. Power consumption is measured
while 64 gray pattern is displayed
The max. power consumption is measured while full black pattern is displayed.

2. The variance of the voltage is

±10%.

3. The transformer output voltage in the inverter must be high considering to the loss of
the ballast capacitor in the inverter.

4. The lamp power consumption shown above does not include loss of external inverter.

5. The life time is determined as the time at which brightness of lamp is 50% compare to
that of initial value at the typical lamp current on condition of continuous operating
at 25º

±2º.
