How does a computer screen work?

Answer 1

It uses binary to create pixels. There are three parts to a pixel; the X coordinate, the Y coordinate, and the color. There is a sort of grid system. The X and Y coordinates tell the monitor where to place the pixel, while the color tells it what color to change it to. The combination of all the millions of pixels creates a picture on-screen.

Answer 2

Each monitor is attached to Watermark sensors, which consist of cylindrical gypsum blocks (plaster of Paris) covered by a metal mesh. The sensors dry out and wet up with the soil throughout the course of the irrigation season. Each sensor has two wires that connect to ports in the Hansen AM400 data logger. Essentially, the logger measures electrical resistance in the sensor and converts that to usable information. Each 6"x8"x2" logger can monitor up to two different sites, with each site containing three sensors buried in one hole at different depths, usually 8", 18", and 30" for shallow rooted crops and 12", 24", and 48" for deep rooted crops. Sensors can be located up to 1000' away from the logger and connected by telephone cable. Each sensor represents a foot or foot and a half section of the soil profile, so the sum of the readings from the three sensors gives the total moisture content of the soil profile.

Answer 3

I will explain how a monochrome (black-and-white) display works. A color display has the same basic mechanism, but with each pixel replaced by a triple of independent elements that produce varying amounts of red, green, and blue. Older CRT monitors (distinguished by their greater depth) work by bombarding a phosphor material with a beam of electrons. The phosphor material is a coating on the inside of the glass that forms the front of the monitor. The strength of the electron beam is changed as it sweeps across the screen, resulting in different amounts of light emitted at different points. This forms an image. Newer LCD monitors use a chemical that can change from being transparent to opaque when an electric field is applied. The monitor has a bright white back light, and each pixel is an electrically controlled screen that allows a specified amount of this light to escape.

Answer 4

Computer Monitors are the things you look at. They now mostly are LCD, or liquid crystal display; or they can be cathode ray tube (CRT). CRT's are much larger, showing up in older computers.

The resolution of a computer is referring on the number of pixels on a screen.

The monitor receives codes from the CPU to put into crystal display.

Answer 5

well basically if you are very clever and scientific then you will be able to use a monior if not then you are screwed basically it takes so much time and effort to set up a monitor i think its got under 3 wires!! and also the power button this is hard for those fat lazy people that dont move all day and dont care about life....

Answer 6

A monitor brings up information stored in servers around the world as words, pictures, and numbers.

Answer 7

There is a little man behind the monitor who draws pictures really fast.

Answer 8

Turn it on. =)
