G141I1-L01 Datasheet, PDF (10/26 Pages) AZ Displays – TFT LCD Tentative Specification

Issued Date: Jun. 18, 2008
Model No.: G141I1 - L01
Tentative
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.
Requirements for a system inverter design, which is intended to have a better display
performance, a better power efficiency and a more reliable lamp. It shall help increase the lamp
lifetime and reduce its leakage current.
a. The asymmetry rate of the inverter waveform should be 10% below.
b. The distortion rate of the waveform should be within 2 ± 10%.
c. The ideal sine wave form shall be symmetric in positive and negative polarities.
* Asymmetry rate:
Ip
| I _p – I _–p | / I_rms * 100%
I -p
* Distortion rate
I _p (or I _–p) / I_rms
