With the continuous innovation of display technology, there are more and more types of display screens. Different types of display products are also used in various industry terminals. What are the fundamental differences between the TFT color screen and the monochrome screen? Here KINGTECH will introduce it to you.
1. Monochrome TFT display screen
The working reasons for the TFT color screen and monochrome screen are completely different. A monochrome screen is composed of 7 pen segments, which are called pixels because there are many points in a range. Monochrome screen is composed of fixed size points, which are arranged in an array. For example, 12864 is composed of 128 horizontal x 64 vertical points. There are many kinds of monochrome screens, such as pen Segment LCD, pattern LCD, dot matrix screen, broken code screen, and so on.
2. TFT colour screen
TFT color screen is filled with liquid crystal material between two parallel plates, and the arrangement of molecules in the liquid crystal material is changed by voltage, to achieve the purpose of shading and light transmission to display images with different depths and scattered patterns. As long as a ternary color filter layer is added between the two plates, the color image can be displayed. Therefore, the working principle of the TFT color screen and the monochrome screen is completely different.
Monochrome TFT display screens are generally used in calculators, watches, remote controls, telephones, etc., while TFT color screens are much more widely used, such as handheld terminals, high-end mobile phones, smart homes, Internet of things devices, health care, artificial intelligence, videophones, walkie talkies, etc. And more and more terminal products will prefer to choose the color TFT screen as the display device of terminal products.
TFT color screen is more expensive than a monochrome TFT display screen because the raw materials and production processes are different. TFT color screen has higher requirements for raw materials, complex processing technology, higher cost, and wider product performance and its popularity is also much higher. Monochrome TFT display screen generally has the problem of high order quantity. Because of its low price, manufacturers of monochrome TFT display screens generally increase the MOQ.
Both TFT color screens and monochrome screens are currently the two most common types of display screens on the market. There is not the best screen, but the one more suitable for the application. There are advantages and disadvantages for both TFT color screens and monochrome screens, so it is better to select them rationally.
