Product Specification

1. General Description

The LP150X08 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 15.0 inches
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 LP150X08 has been designed to apply the interface method that enables low power, high speed,
low EMI.
The LP150X08 is intended to support applications where thin thickness, low power are critical factors
and graphic display are important. In combination with the vertical arrangement of the sub-pixels, the
LP150X08 characteristics provide an excellent flat display for office automation products such as
Notebook PC.

3. Electrical Specifications
3-1. Electrical Characteristics

The LP150X08 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.

Operating Frequency
Discharge Stabilization Time
Power Consumption
Life Time

Note : The design of the inverter must have specifications for the lamp in LCD Assembly.

The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced by

the characteristics of the DC-AC inverter. So all the parameters of an inverter should be carefully
designed so as not to produce too much leakage current from high-voltage output of the inverter.

When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of

the lamp and the inverter(no lighting, flicker, etc) never occurs. When you confirm it, the LCD–

Assembly should be operated in the same condition as installed in you instrument.

1. The specified current and power consumption are under the VCC=3.3V, 25C, 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 from LVDS TX to the mating

connector.

3. The variance of the voltage is  10%.

4. The voltage above VS should be applied to the lamps for more than 1 second for start-up.

Otherwise, the lamps may not be turned on. The used lamp current is the lamp typical current.

5. The output of the inverter must have symmetrical(negative and positive) voltage waveform and
symmetrical current waveform.(Unsymmetrical ratio is less than 10%) Please do not use the inverter
which has unsymmetrical voltage and unsymmetrical current and spike wave.
Lamp frequency may produce interface with horizontal synchronous frequency and as a result this may
cause beat on the display. Therefore lamp frequency shall be as away possible from the horizontal

synchronous frequency and from its harmonics in order to prevent interference.

6. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.
TS is the time required for the brightness of the center of the lamp to be not less than 95%.

7. The lamp power consumption shown above does not include loss of external inverter.
The used lamp current is 6.0mA

8. The life is determined as the time at which brightness of the lamp is 50% compared to that of initial
value at 6.0mA

9. Requirements for a system inverter design, which is intended to have a better display performance, a
better power efficiency and a more reliable lamp, are following.
It shall help increase the lamp lifetime and reduce leakage current.
a. The asymmetry rate of the inverter waveform should be less than 10%.
b. The distortion rate of the waveform should be within 2  10%.
* Inverter output waveform had better be more similar to ideal sine wave.

※ Do not attach a conducting tape to lamp connecting wire.

If the lamp wire attach to a conducting tape, TFT-LCD Module has a low luminance and the inverter

has abnormal action. Because leakage current is occurred between lamp wire and conducting tape.

3-2. Interface Connections

The interface connections are compatible with ISP (Industry Standard Panels) 15.0” Mounting and Top
Level Interface Requirements (Version2, June,2000) defined by SPWG (Standard Panels Working
Group). This LCD employs two interface connections, a 30 pin connector is used for the module electronics

and the other connector is used for the integral backlight system.
The electronics interface connector is a model IS100-C30R-C15 manufactured by UJU. The pin
configuration for the connector is shown in the table below.
