Display screens are used in all aspects of our lives, such as cell phones, home TVs, home appliances, calculators, computers, etc. we use every day. There are many types of screens, and there are many types of optical LCD screens, plus the new OLED flexible screens, min-led screens, and microLED screens. So what kinds of displays are there? How are they defined?
Today, i am going to introduce 7 types of LCD panel displays to all of your guys:
1.Segment code LCD screen
Segment code LCD screens were developed in Japan in the early stage and introduced to China in the 1980s. They mainly replaced LED digital tubes (consisting of 7 pen segments, used to display numbers 0-9), such as calculators, clocks, etc., and the display content is all numbers. , It is also relatively simple.
There are also many different names, such as pen-segment LCD screens, small-size LCD screens, 8-character screens, and patterned LCD screens.
2. Dot-matrix screen
Dot-matrix screens are divided into LCD dot matrix and LED dot matrix screen. Simply put, there are many dots in a range and are called pixels. Dot-matrix LCD pixels are composed of fixed-size dots. These dots are arrayed. Arrangement; for example, 12864 is composed of 64 points in the horizontal direction 128X and the vertical direction.
3. TFT color screen
TFT is a classification of LCD, and it is the prototype of all current LCD screen improvements. Like the screen used on older mobile phones, it also belongs to the dot-matrix type. It pays attention to pixels, and the color in it is the concept of the color scale.
Color gradation is an index standard that indicates the intensity of the brightness of the liquid crystal display, which is commonly referred to as the color index. There are generally three-color qualities commonly seen on the market: 256 colors, 4096 colors, and 64K (ie 65536) colors or even higher 260,000 colors. The display effect of different color quality is different.
The display is divided into three categories: ordinary text, simple images (images like cartoons, mainly menu charts and drawn standby screens), and photo images. As for users who have higher requirements for photo quality, 64K color is of course a better choice.
4. LED screen
The LED screen is simple. It is a screen made up of many LED lights. The signboards in Dajiexiaogang are all of this kind.
5. OLED screen
The OLED screen displays images through the self-luminescence of pixels. From this perspective, OLED screens are more advanced in technology than LCD screens. In addition, the OLED screen can be made thinner in thickness, which is conducive to the thickness control of the whole machine.
On the whole, they can be classified as LCD and OLED on a large scale. The two types of screens are essentially different in terms of luminescence. One is illuminated by an external light source, and the other is self-luminous. Judging from the current development situation, these two camps will continue to be used to meet the needs of different users for color performance.
6. MiniLED screen
Mini LEDs, also known as “sub-millimeter light-emitting diodes”, are LEDs with a size of about 100 microns first proposed by Epistar. Mini LED is a transition technology between traditional LED and micro-LED and is an improved version of a traditional LED backlight.
7. MicroLED screen
The microLED screen is a new generation of display technology with a matrix of miniaturized LEDs. In short, LED backlights are thinner, more compact, and LED units are smaller than 100 microns. Like OLED, each pixel is individually addressed and driven to emit light (self-luminescence).

Thank you Nora for sharing your knowledge of display panel technology.
Hi Grant, i am glad that my article is work for you:)
If there is any projects relate to the LCD/OLED displays, welcome to reach me at nora.wong@toppoplcd.com for more details.
