At present in the market, LCD screen has been widely used in all walks of life, such as mobile phones, TV sets, small household appliances, calculators, air conditioning thermostat and so on, screen is also all kinds of, let a person difficult to distinguish. According to my understanding, there are many kinds of LCD screen, in my understanding there are: segment code LCD screen, dot matrix screen, TFT color screen, OLED, LED, IPS and so on. So what’s the difference? 1, segment code LCD screen was early developed in Japan, introduced in China in the 1980s, mainly to replace LED digital tube (composed of 7 pen segments, used to display numbers 0~9), such as calculators, clocks, etc., the display content is digital, also relatively simple. There are many kinds of name, such as pen segment LCD screen, small size LCD screen, figure 8 screen, pattern LCD screen.
2, lattice screen lattice screen is divided into LCD lattice, LED lattice screen is simply said to be in a range of a lot of points composed of called pixels, lattice LCD pixels are composed of fixed size points, these points are arranged in the way of array; For example, 12864 is made up of 128 points horizontally X 64 points vertically
3, TFT color screen TFT is a classification of LCD, is the prototype of all the current LCD screen improvement, like the older mobile phone is used in the previous screen, also belongs to the lattice class, pay attention to pixels, where the color is the concept of color level. Color level is the index standard that indicates the brightness intensity of LCD screen, also known as the color index. Now commonly seen on the market generally have three color quality: 256 color, 4096 color and 64K (that is 65536) color or higher 260,000 color. The display effect varies with color quality. The display is divided into three categories: plain text, simple images (images like cartoons, mainly menu charts and drawn standby screens), and photo images. As for the photo quality requirements of higher users, 64K color is of course a better choice.
4, LED screen LED screen is simple, is composed of a lot of LED lights of a screen, street small port signs are this
5. OLED screens display images by self-lighting pixels. In this sense, OLED screens are more advanced than LCD screens. In addition, the OLED screen can be thinner, which is conducive to the thickness control of the whole machine. TFT LCD Module.
As a whole, they can be classified as LCD and OLED on a large scale. The two screens are fundamentally different in terms of luminescence, one is illuminated by external light sources, the other is self-luminous. From the current development situation, these two camps will continue to follow the use of color to meet the needs of different users.
