1. General Description

The LP154W01 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

’

2. Absolute Maximum Ratings

The following are maximum values which, if exceeded, may cause faulty operation or damage to the unit.

3. Electrical Specifications 3-1. Electrical Characteristics

The LP154W01(TLA2)requires two power inputs. One is employed to power the LC D electronics and to

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

8. 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.

9. The lamp power consumption shown above does not include loss of external inverter.The applied lamp current is a typical one.

Note)

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%.

3-2. Interface Connections

This LCD employs two interface connections, a 30 pin connector is used for the module electronics interface and the other connector is used for the integral backlight system.

The electronics interface connector is a model IS100-C30R-C15 manufactured by UJU.

3-3. Signal Timing Specifications

This is the signal timing required at the input of the User connector. All of the interface signal timing should be satisfied with the following specifications and specifications of LVDS Tx/Rx for its proper operation.

3-5. Color Input Data Reference

The brightness of each primary color (red,green and blue) is based on the 6-bit gray scale data input for the

3-6. Power Sequence

2. When the interface signal is invalid, be sure to pull down the power supply for LCD VCC to 0V.

3. Lamp power must be turn on after power supply for LCD and interface signal are valid.
