What is the LCD screen, the display screen

A monitor is an IO device of a computer, i.e., an input and output device. A monitor is a device that displays an operation screen on a computer.

It is a kind of display wheel that displays a certain electronic file on the screen through a specific transmission device. It can be divided into cathode ray tube display (CRT), plasma display PDP, liquid crystal display LCD. The monitor is only an output device of the host, which has no impact on the computing performance and grade of the computer, but the monitor is an absolutely indispensable output device.

Without it, we would have no way to know the computer's travel status, and we wouldn't be able to do anything with the computer. On the other hand, the monitor can directly display the commands entered by the keyboard, or the track of mouse activity, and is also the most important auxiliary device that helps us control the computer.

Display composition

1. LCD module.

Glass substrate: Inside are liquid crystals and grid-like printed circuits. Timing control:

It is used to generate the timing and voltage required for the deflection of liquid crystal molecules in a controlled talking bench. Lamp: Produces a white light source.

Backlight: Reflects the light generated by the lamp onto the LCD screen.

2. a control panel.

The control board plays the role of signal conversion. Converts signals from various input formats into signals with fixed output formats. For example, the input signal to the screen of 1024 x768 can be 768, etc., and finally converted into the output format 1024 768.

3. Inverter.

High pressure is generated and is used to light the tube.

It is not difficult to understand the display screen from the literal meaning. But from the product structure and type and use: Roughly divided into several types 1Computer Monitor2Control panel display display rebate 4LCD splicing screen 5LCD TV.

LCD display**.

AOCI2369V,This display is oriented to the low-price market,As a twenty-three inches,Using the same IPS material as the Apple mobile phone display,With 1920X1080 resolution display,Its market price is about 900 yuan。 According to the feedback of netizens, this monitor can be described as a value-for-money product, with a delicate display effect and a narrow bezel design, which is very fashionable in foreign countries.

LCD display structure.

The LCD screens we see have glass substrates. The glass substrate is extremely demanding, must be produced using float glass, and the surface must be very flat, but also very thin. The surface of this glass substrate must be coated with a conductive layer of indium oxide or tin oxide, and it must be transparent, which is the ITO coating in LCD liquid crystal displays.

The outer leads of the glass substrate are welded by a special welding method, using conductive rubber strips or conductive tapes, which is significantly different from what we know about soldering with tin. The glass substrate is a very precise and good bending component, and as long as it causes a little damage, it will lead to the scrapping of the glass substrate.

LCD liquid crystal display principle.

The LCD display uses the color display of the glass panel light transmission technology to make the bottom panel glow as a whole, achieving a true flat surface. LCD LCD displays are composed of multiple layers of structure, which include two layers of glass panels, liquid crystal material in the middle of the glass panel, a backlit panel, a reflective film, and the light source tube around them.
