With a 100-year head start over more modern screen technologies, the CRT is still a formidable technology. It’s based on universally understood principles and employs commonly available materials. The result is cheap-to-make monitors capable of excellent performance, producing stable images in true colour at high display resolutions. But in the world of miniaturization, Cathode ray tubes (CRT) are giant dinosaurs waiting for extinction. A CRT uses a single-point hot electron source that is scanned across the screen to produce an image.

Introduction

A type of display screen that has a touch-sensitive transparent panel covering the screen. Instead of using a pointing device such as a mouse or light pen, you can use your finger to point directly to objects on the screen.
Although touch screens provide a natural interface for computer novices, they are unsatisfactory for most applications because the finger is such a relatively large object. It is impossible to point accurately to small areas of the screen. In addition, most users find touch screens tiring to the arms after ....etc

Capacitive Touch-Screens
How it’s Made
A capacitive touch screen is an all glass touch screen with a transparent metallic conductive coating.
The LCD display is found beneath the glass and conductive layers.
How it Works
There is a low voltage charge that is generated from the corners of the screen and distributed throughout the conductive layer.
When a finger touches the screen it draws a minute amount of current, creating a drop in voltage.
The devic ....etc
