The above reasons make the LCD display silent for quite a long period of time.

Time Frame: 1995-1997
Generation III

1.Constant Production method improvement sharply reduce production cost ,

such as the evolution of Glass substrate size technology ,

low deffect ratio technology and etc, consequent effects a low cost LCD.

2.Advanced wide viewing angle technology was well developed.

3.Contrast Ratio, brightness and performance were highly improved.

4.Lee-Ming commercialized this device as handy components, integrate the LCD Panel

and Driver Board together as module piece, simply 12V DC and Video signal input.

5.The compact dimension, high quality picture, low electricity consumption and

easy installation make manufactures in different field easily replaced CRT screens by LCD Display.


Time Frame: 1998-20XX
