TFT LCD vertical scan rate


New member

I would like to know if it is possible to increase the vertical scan rate of a TFT LCD to 200Hz or more.

As I notice Sony TFT LCDs have the highest vertical scan rate (85Hz) among the other LCD manufacturers. Yet sony did not produce the lcds. They just buy the lcds from LG & Philips.

Why don't they make it higher?

Is it just the manufacturers think that 85Hz is enought for the market or there is a limitation in the hardware part( like the response rate of the liquid crystal)???

I believe that the biggest reason is that your eye can not perceive anything near 200Hz.

Why have a faster refresh when you can't see it?
