Liquid Crystal Display
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. FOS, and reliability test condition is at 6.0mA
5. 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 the maximum lamp current (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 the maximum lamp current(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
