Advantage and disadvantage compare to CRT display
Time Frame: 1990-1994
1. LCD was 4 to 5 times more
expansive than CRT display.
2. LCD has narrow viewing angle
3. Low Contrast ratio and Brightness
4. The LCD power consumption
is less than CRT.
5. The LCD radiation is much
less than CRT.
6. Driver PCB is Extremely High
Level Developing Know How. Only few well-known big
are capable to developing this circuit.
The above reasons make the LCD display silent for quite
a long period of time.
Time Frame: 1995-1997
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
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
easy installation make manufactures in different field
easily replaced CRT screens by LCD Display.
Time Frame: 1998-20XX
The LCD Market scale was ten times growth for the passed
three years form 1994 - 1997,
and Experts predict a hundred times growth for coming
