TFT (Thin Film Transistor) is a type of LCD display and is not related to touchscreen technology in any way; a better question would be, "What is the difference between resistive touchscreens and capacitive touchscreens?"
Resistive screens are an older design, in which two electrically conductive layers are separated by an insulating gap. When pressure is applied, the resistance between the layers changes at that point. While cheap and reasonably durable, they require styluses, don't support multi-touch and can reduce the quality of the displayed image.
Resistive screens were used in the original Palm Pilot and later Palm devices, in some portable games like the Nintendo DS, and in some current applications where their low price outweighs their limitations.
Capacitive touchscreens use newer technology that also relies on electrical conduction, but senses changes in capacitance rather than resistance. Since human skin conducts electricity, moving a finger near the electrostatic field of a capacitive touchscreen will change the field, and the change can be measured and interpreted as a touch. Although they can be triggered by metallic objects, cloth, and other materials and are more expensive than resistive sensors, capacitive screens don't require syluses, support multi-touch, and can be made perfectly transparent.
Capacitive screens are used in many new smartphones and tablets, including the iPhone, iPad, the Droid Incredible, Blackberry Storm, etc. The iPod trackwheel is an example of this technology used without a display.
Aluminum screens are more durable and resistant to corrosion, while fiberglass screens are more flexible and easier to install. Aluminum screens are also more expensive than fiberglass screens.
Fiberglass screens are lighter, more flexible, and less expensive than aluminum screens. Aluminum screens are stronger, more durable, and resistant to corrosion. Fiberglass screens are easier to install and repair, while aluminum screens provide better visibility and are more suitable for high-traffic areas.
The thin layer technology of the capacitive touch screen allows for a sharper picture than other touch screens. Also, since the capacitive touch screen is responsive to human touch but not most other objects, accidental touches are less of a problem.
They dpon't make LED screens yet just LCD and plasma screens.
The different types of window screens available in the market include fiberglass screens, aluminum screens, solar screens, and pet-resistant screens. Each type has its own unique features and benefits, catering to different needs and preferences.
It is capacitive, so not heat or resistive, so not pressure. Capacitive screens use your body's natural electrostatic field (in this case, the field around your finger). A Google search will help you learn more.
A resistive touchscreen panel is composed of several layers. The most important are two thin metallic electrically conductive and resistive layers separated by thin space. When some object touches this kind of touch panel, the layers are connected at a certain point; the panel then electrically acts similar to two voltage dividers with connected outputs. This causes a change in the electrical current which is registered as a touch event and sent to the controller for processing.
PSP's are better. They have PSStore and better screens and graphics. And they are sony, not Nintendo, which have lousy games(mario, pokemon).
CRT monitors are the old traditional fat monitors that look like TVs, and TFT are flat screens.
The best types of screens for screen doors are typically made of fiberglass or aluminum mesh. These materials are durable, resistant to tearing, and provide good visibility and airflow.
CRT screens can work with an input signal with varying refresh rates while TFT displays have a manufacturer-set refresh rate. TFT screens however produce clearer images than CRT.
LCD's (liquid crystal display) tend to have a higher resolution, are lighter, and use less power than plasma screens. However, plasma screens allow for better viewing angles.
