LP150U1

Liquid Crystal Display

Product Specification

1. General Description

The LP150U1-A2 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent

Lamp(CCFL) 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 15.0 inch diagonally

measured active display area with UXGA resolution(1200 vertical by 1600 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 262,144 colors.

The LP150U1-A2 has been designed to apply the interface method that enables low power, high speed low

EMI. Flat Link must be used as a LVDS(Low Voltage Differential Signaling) chip.

The LP150U1-A2 is intended to support applications where thin thickness, low power are critical factors and

graphic displays are important. In combination with the vertical arrangement of the sub-pixels, the LP150U1-A2

characteristics provide an excellent flat panel display for office automation products such as Notebook PC.

2. Electrical Specifications

2-1. Electrical Characteristics

The LP150U1-A2 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.

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 your instrument.

Notes: 1. The specified current and power consumption are under the Vcc = 3.3V , 25°C, 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 voltage above Vs should be applied to the lamps for more than 1second for start -up.

Otherwise, the lamps may not be turned on.

4. 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 interference with horizontal synchronous frequency and as a result

this may cause beat on the display. Therefore lamp frequency shall be as away as possible from

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

5.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%.

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

7. The life time is determined as the time at which brightness of lamp is 50% compared to that of

initial value at the typical lamp current on condition of continuous operating at 25± 2°C.

2-2. Interface Connections

Interface IC must be LVDS compatible, part No. THC63LVDF83A made by Thine, or use the compatible interface ICs made by either TI or NS. 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 FI-XB30S-HF10 manufactured by JAE. The pin configuration for the connector is shown in the table below.
