Display screen is applied in every aspect of our lives, our daily use of mobile phones, the family TV sets, household appliances, calculators, computers, etc., commercial use vending machine, coffee machine display screen, ATM, arcade games, etc., hospitals and beauty institutions with the various needs of medical cosmetology instrument human-computer interaction, HMI in the field of all kinds of industrial big machines, etc.

There are many types of display screens, and there are many kinds of optical LCD display screens. In addition, the newly released OLED flexible display screen, mini LED display screen, micro LED display screen and so on. So what are the types of display screens ? How are they defined? 

Here are 7 common types of displays screens :

1. segment code LCD display screen

Segment code LCD screen was developed in Japan in the early stage and introduced into China in the 1980s. It is mainly used to replace LED digital tubes (composed of 7 pen segments, used to display Numbers 0-9), such as calculators and clocks. The display contents are all Numbers and relatively simple.

There are a lot of ways to call it, such as pen segment LCD, small size LCD, 8-character screen, pattern LCD, and so on.

2. Dot matrix display screen

Dot matrix screen can be divided into LCD dot matrix and LED dot matrix screen. In simple terms, there are many dots in a range and they are called pixels.For example, 12864 is made up of 128X horizontal and 64 vertical points.

3. TFT color display screen

TFT, a classification of LCD, is the prototype of all the current LCD screen improvements. Like the screen used in old mobile phones in the past, TFT is also a lattice type, which pays attention to pixels, and the color is the concept of color levels.Level is the index standard that expresses liquid crystal display screen brightness intensity, namely the color index that says commonly.Now the market generally see three color quality: 256 color, 4096 color and 64K(namely 65536) color and even higher 260,000 color. The display effect of different color quality is different.Displays are divided into three categories: plain text, simple images (like cartoons, mostly menu charts and drawn standby) and photo images.For users with higher photo quality requirements, 64K color is certainly a better choice.

4. LED display screen

LED screen is simple, is a lot of LED lights composed of a screen, the street signs are small harbor.

5. OLED display screen

OLED screens display images by emitting light from pixels.In this respect, OLED screens are more technologically advanced than LCD screens. In addition, the thickness of OLED screen can be made thinner, which is conducive to the thickness control of the whole machine.

On the whole, they can be classified as LCD and OLED in a wide range. The two kinds of screens are essentially different from each other in terms of luminescence, one is illuminated by external light sources, the other is self-emitting light. Look from current development situation, these two big camp still will continue to follow use go down, satisfy different user to colorific expression demand.
