Product General Specification
LM151X1
LiquidCrystal Display
1. General Description
The LM151X1 LCD is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode
Fluorescent Tube(CCFT) back light 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 inch 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 8-bit gray scale signal for each dot, thus, presenting a palette
of more than 16,777,216 colors.
LM151X1 has been designed to apply the interface method that enables low power, high
speed low EMI. Panellink must be used as a LVDS(Low Voltage Differential Signaling) chip.
The LM151X1 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 LM151X1-D2MN characteristics provide an
excellent flat panel display for office automation products such as monitors.

Product General Specification
2. Electrical Specifications
LM151X1
LiquidCrystal Display
The LM151X1 requires three power inputs. Two inputs are employed to power the LCD
electronics and to drive the voltages to drive the TFT array and liquid crystal. And the third
input which powers the backlight CCFL, is typically generated by an inverter. The inverter is an
external unit to the LCD.

Notes: 1. VDD input is the analog power supply for the TFT array and liquid crystal, and VCC
input is the digital logic power supply for the LCD electronics.
2. The input current shall be measured at VDD of 5.0Vdc at 25 , refresh rate of 60Hz,
and clock frequency of 65MHz under 9 gray pattern.
3. Power supply kick off current means power supply input current at the moment of
LCM power on. This current is higher then the current at the normal operating
condition and it lasts for 50~100ms.
4. The backlight input current shall be measured at the ground cable and does not
include loss of external inverter.
5. Voltages at both ends of the lamp.
6. Voltages at secondary side of transformer using the balancing capacitor, 22pF in
inverter. These voltages can be changed with customers own design of inverter.
7. The life time is defined 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 25 2 .
