How to clean an LCD screen

No matter where an LCD screen is located, we will always have the need to clean it. Clean an LCD screen can seem like a difficult task, but there are some simple ways to clean it them without damaging or marking the surface.

There are many cleaning solutions for LCD displays in stores. However, these can be a bit expensive and sometimes useless. It is for this reason that in this article we show you how to clean an LCD screen with available materials, and easily.

How to clean screen

Alcohol solution

We recommend using a simple alcohol solution to clean an LCD screen. This solution is composed of 1 part distilled water and 1 part 50% isopropyl alcohol. Be careful that isopropyl alcohol is flammable.

The Isopropyl alcohol 50% is common. But if you find a 70%, 91%, or 99% isopropyl alcohol, adjust the formula to use less alcohol and distilled water.

By mixing these two components in a bottle, will produce a real solution cleaning LCD screens. Remember not to use tap water, distilled water only.

How to clean screen

NEVER use tissues (Kleenex type) to clean the screen. That is so inefficient, that once it happens, it will leave parts around the screen. Try to find microfibre cloth to clean the screen. Cloths that come with glasses are usually a good choice.

Never spray any liquid directly on the LCD screen. Gently wipe the screen up and down and wait for it to dry.

Be careful not to let the liquid drops the sides of the monitor.

In addition make sure not to press hard on the LCD screen. You can permanently damage an LCD screen by pressing on it too hard.

How to clean screen

Dust

If you only have dust on the screen, no need to completely clean. To remove all dust, what to do is clean it away with a microfiber cloth. Simply clean the screen very gently tip the tip with the cloth.

How we could see, cleaning a screen should not be an expensive or complicated task to perform, just only a little patience, cloth, alcohol and water to make a screen look bright as day one.

Input and Output Peripherals

The I/O (input and output) peripheral are used primarily for communication between the computer and the external environment. They provide the ability to enter commands to the PC, and vice versa, i.e. send commands to outside to perform some task on a given device.

In addition, they also have the peculiarity of manage their own transfer rates, without the computer having to deal with the balance of the transmission speed. Among these components we can mention keyboard, monitor and printer.

Computer peripherals

CD/DVD Drive (Input and Output): Its function is to rotate an optical disk at a constant speed to transfer programs or data from this disk to the computer or vice versa. This operation is performed through a recording and reading head which moves back and forth on the disc surface. The data recorded on the disc can be read and used as a reference in a future operations.

Computer peripherals

Hard Disk or HD (Input and Output): This types of storage units are characterized by greater storage capacity and faster operation.

It consists of a series of discs of rigid material, grouped in a single axis, each disc having a head. The heads float on the surface of the disc supported on a cushion of air, which means they must be kept in sealed boxes to avoid problems caused by dust and other foreign matter.

Computer peripherals

Monitor (output device): This is the device that is used to allow the user to view the data and graphics elements needed to perform its task. Without the monitor, it would be virtually impossible to operate a computer. This screen is connected to the computer through the port of the video card.

Computer peripherals

Mouse (input device): The mouse is placed on any flat surface, and when it moves, it also moves the cursor on the screen with extreme agility. Thus, the user can move to any part of the screen, press the button and select the desired operation and perform all possible actions.

Computer peripherals

Joystick (Input device): The joystick has the particularity of being able to move in many directions and axles, smoothly and a very agile way, which makes especially useful for all sorts of games and other implementations. This device is moved similarly to the mouse, ie, the movements the user makes with the joystick are repeated on the screen.

Computer peripherals

Printer (Output device): This peripherical is used to print data on paper. Currently, there are three main types of printers: dot matrix, ink jet and laser.

Computer peripherals

Modem (Input and output): The modem is a signal conversion device, which is capable of transmitting data over phone lines. The MODEM term is derived from the MOdulation and DEModulation words. Used for internet connection.

Computer peripherals

Keyboard (input device): The most important means of data entry, which establishes a direct relationship between the user and the computer.

Computer peripherals

Scanner (Input device): An image scanner is an input device that allows scan pages or pictures from printed material such as magazines, newspapers and posters, and convert them to digital data so they can be used by programs such as Photoshop, OCR applications and other software designed to work with images.

Computer peripherals

Scanned images can be modified and reproduced again by suitable printing equipment. In this way we can make posters or any other type of work using photographs.
