Product Specification
1. General Description
The LG Electronics model LM151X1-G LCD is a Color Active Matrix Liquid Crystal Display with
an integral Cold Cathode Fluorescent Tube(CCFT) back light system. The matrix employs aSi 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 16,581,375 colors.
LM151X1-G 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-G 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-G characteristics provide an
excellent flat panel display for office automation products such as monitors.

Note: 1. The Relative Humidity must not exceed 95% non-condensing at temperatures of 40¡É or less.
At temperatures greater than 40¡É, the wet bulb temperature must not exceed 39¡É.
3. Electrical Specifications
The LM151X1-G 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 V
input is the digital logic power supply for the LCD electronics.
2. The input current shall be measured at V
DD
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 customer’s 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.

4. Optical Specifications
Optical characteristics are determined after the unit has been ‘ON’ and stable for
approximately 30 minutes in a dark environment at 25C. The values specified are at an
approximate distance 50cm from the LCD surface at a viewing angle of Φ and θ equal to 0°
and aperture 1 degree. The test equipment is PhotoResearch Prichard SpectroRadiometer
Model 1980B-SC or equivalent. The input signal voltage and timing specification are V
5.0Vdc, AVDD of 3.3Vdc and VESA XGA @60Hz respectively. The input current of backlight is
8mA(FBL = 50KHz) at the ground terminals.

Notes 1. Contrast Ratio (CR) is defined mathematically as:
(Surface Brightness with all white pixels)
(Surface Brightness with all black pixels)
Contrast ratio shall be measured at the center of the display (Location 1).
2. Average Brightness is the average of brightness value at location 1 to 5 with all
pixels displaying white.
B1 + B2 + B3 + B4 + B5
B(AVE) =
5
3. The variation in surface brightness, SBV is defined as :
Maximum (B1, B2, ....B13) - Minimum (B1, B2, ....B13)
Average (B1, B2, .... B5)
Where B1 to B13 are the brightness with all pixels displaying white at 13 locations.
