Re: On a TFT, how many transistors does each pixel have?
0 to 4. Zero if it is passive and 1 to 4 if active. The more transistors, the sharper the image/contrast, but also the higher the cost.

Re: Is an active matrix LCD also called a TFT?
Yes. TFTs can be active (1 to 4 transistors per pixel) or passive where the screen is refreshed. The more transistors, the higher the cost.

Re: What is better a TFT or IPS
IPS is a TFT. It is a display where there is one or more transistors attached to each pixel. A TFT can also be passive which means there is no transistors, but the screen is refreshed.

Re: What has a longer life span? AMOLEDs or TFTS
TFTs do, although the life span of half-life of OLEDs is getting longer.

Re: Can TFTs be made round
Yes, it is possible to make a round TFT,
This would be a custom LCD and the cost is very expensive and has a high MOQ

Re: Does the LED backlight create noise?
No, LEDs are DC (Direct Current) and do not create noise that can be seen on CCFL and EL backlights that are AC driven

Re: Chat is a COB Character LCD?
I think you mean what is a COB LCD?
COB stands for Chip on Board. That means there is a Printed circuit board attached.

Re: How can I warm up a LCD in cold winter time?
The lowest cost method to add heat to a display is to add several resistors around the glass.
