Computer Screen Components – Computer screens, specifically LCD screens, work through light blocking technology.

Lcd screens consist of two pieces of polarized glass called the substrate. The liquid crystalline material is present between these two glass pieces, creating a rear light that is a foundation and background of the leading light, passing through the substrate.

The screen is a type (CRT), another type of screen consisting of several minimal elements called pixels that form the image.

Whenever these units are smaller, the more precise and accurate the picture, the general and straightforward components of computer screens. Still, there are many other details of components for each type of screen, with details:

LCD Components

Thinner and lighter than CRT screens contain a layer of crystals specially made for these screens installed on an electrical grid.

When small charges reach the screen, they spread in different directions.

Each of these charges interacts with other crystals to change the color of each crystal according to interaction with them and contains a small fluorescent lamp or LED along the long edge of the screen to light up.

CRT Components

Researchers estimate that they contain a glass tube lined with a large amount of lead up to 4 pounds in quantity and weight and include a cadmium element or metal. Which are somewhat chemical. till this metal is highly

Chemical LCD Components

These screens are advances compares to their predecessors, containing chemicals such as crt but safer. Yet, they still have small amounts of lead and mercury, specifically in fluorescent light models and nitrogen trifluoride, which it uses in the process of manufacturing liquid crystals.

This chemical is famous for its impact on global warming, more than 17,000 times the second carbon monoxide effect.

How does the computer screen work? The computer screen, specifically the LCD screen, works through the technology of light blocking.

It contains two pieces of polarized glass and liquid material between them, as electrical currents pass along the crystal particles to allow the passage of different levels of light for the second screen, to show the colors and images seen by the computer user, i.e., most computer screens use active-matrix technology, they contain thin transistor pieces arranged with small capacitors.

And are regularly stakes on the screen glass to process pixels after an electric current passes through a particular row of transistor pieces. An electrical charge is sent down a specific column of fragments in the matrix, and at the same time. It stops operating all the other rows that intersect with this column. The condenser retains the electrical charge to show colors and images as the process continues.

Another type of LCD technology is called the passive matrix. Using a network of conductive metal to charge all pixels, is a low-cost production technique compared to its counterparts. Still, it is rare to use because the response time is slow. And inaccurately controls the voltage compared to the active matrix.

Tips for Keeping your Computer Screen Permanent

Here are the top tips for maintaining and increasing the durability of your computer screen. Use a condom to protect the screen from high power that may damage it. Keeping the vents on the net or their sides open and not covering them.

Covering these openings causes them to overheat, damaging their internal components and shortening their lives. A clean drawing brush or vacuum brush can be used to remove dust accumulating on the screen vents.

Leaving the screen turned on when frequently used during the day and not turning it off and restarting too much moves components from cold. Uncharted to warm and electrified, increasing the likelihood of damage.


The computer’s screen consists of a set of parts that help it show clear images and colors, and each type of computer screen has specific components different from the other. This also makes it further in the principle of its work. As computer screens vary between CRT screens consisting of cathode ray tubes, LCD screens, and crystal screens.

These screens vary by the type of lamps used in them, where they are placed, in addition to their thickness. The shape of the computer screen from the inside and the computer screen must be kept from the knowledge. While following many of the instructions provided by the manufacturer to protect it from damage
