You can not get to the LCD without taking the device apart first. LCD screen is the panel that is inside the device, which displays the image. It is the part that you can touch without disassembling the device.
Touchscreen (AKA digitizer) is the thin transparent layer of plastic, which reads the signal from the touch and transports it to the processing unit. What many users fail to take into the consideration, is that the touchscreen and the actual LCD screen are two independent parts. Most households will have at least one device with a touchscreen, and our customers are no exception.Īs a result of the wide popularity, these screens brake on an occasion. Nowadays, touchscreen devices have established themselves as an industry standard for most smartphones, tablets and a large fraction of laptops. Later, in 1985, the University of Toronto group including Bill Buxton developed a multi-touch tablet that used capacitance rather than bulky camera-based optical sensing systems. It was using a glass panel with a camera placed behind the glass. Multi-touch technology development began in 1982, when the University of Toronto’s Input Research Group introduced the first human-input multi-touch system. The touchscreen prototype was developed in 1977 by Ben Stumpe, a Danish electronics engineer. Some touchscreens can be controlled by fingers others may require the use of gloves with a particular type of coating, or the use of a special stylus pen. The touchscreen enables the user to interact directly with what is being displayed, rather than using a mouse, touchpad, or any other intermediate device. A touchscreen is an electronic input device that the user can control with single or multi-touch gestures.
