Overview of Adaptive Addressing
"Adaptive Addressing" for enhanced low
temperature operation.
Cold temperature LCD operation:
There are basically three factors that cause a problem at
low temperatures. Each of these problems will be discussed
briefly, and then we will give an overview of how Adaptive
Addressing overcomes these limitations:
- High Multiplex Rates - The higher the
multiplex rate, the worse the performance at low
temperatures.
- Fluid Threshold Drive Voltage - As the
temperature changes, the voltage threshold of
the liquid crystal fluid changes.
- Response Time - As the temperature changes,
the response time of any display get longer.
If you want a high resolution graphics display,
item 1 above becomes a problem. Items 2 and 3 are
closely related, and are a function of the fluid
used to make the display. Because of this, they are
totally out of your control.
