CM2225 LITEMAX, CM2225 Datasheet - Page 11

• Manufacturer Part Number: CM2225
• Description: WXGA LCD Display
• Manufacturer: LITEMAX

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.
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.
