Is there any hardware needed to make a PC touch screen?
One would have a difficult time building their own touch screen.There are a few different touch screen technologies out there. The first (and usually most rugged) is an infrared "grid" that covers the screen. Touching the screen breaks the beams, and that is translated into x and y coordinates.The more common method is a resistive film that covers the screen. The film has microscopic wires going through it, and when you touch the screen, the wires are shorted together, once again giving x and y coordinates.A third type (used in the iPhone) is a capacitive touch screen. These are very rugged, however they can't be activated with, say, a pencil eraser like the resistive film.In the capacitive system, a layer that stores an electrical charge is placed on the glass panel of the monitor. When a user touches the monitor with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases.
How do touch screen monitor controllers work?
A basic touchscreen has three main components: a touch sensor, a controller, and a software driver. The touchscreen is an input device, so it needs to be combined with a display and a PC or other device to make a complete touch input system. Our website http://www.HomeTouchSystems.com will explain the difference between all types of touch screen and USB and 232 controllers. This is a link to our USB controller page http://www.hometouchsystems.com/TouchScreen/touch-screen-controllers.aspThis is my best description of a resistive touch screen: The 4-Wire resistive touch screen is the preferred solution for low cost applications. It consists of a conductive bottom layer (ITO Glass or Film) and a conductive top layer (ITO Film). The two layers are suspended by many very small spacer dots. When a certain point is touched, the top layer contacts the bottom layer and a voltage charged by the controller is applied to the bottom layer's electrodes. The coordinate X axis of the touch point can be detected by measuring the voltage value thru the top ITO layer and the coordinate Y axis of the touch point can be detected in the same way by changing voltage input to the top layer's electrodes. All of the above and more can be found at our web site http://www.HomeTouchSystems.com
Is a Thin Film Transistor used as a touch screen?
Yes TFT LDC is used in many TSDs
What is the difference between capacitive and resistant touch screens?
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.
What is the difference between polyester film and bopp film?
Polyester is a polymer chain of Ester monomer and BOPP is a Polymer chain of Propylene monomer. Harit Singhvi
What is the Smart board?
A smart board is an interactive whiteboard that can control your computer like a touch screen monitor, it also does a bunch of other cool things.
