What is the Difference Between a Color TFT Display Screen and a Monochrome TFT Display Screen?

With the continuous innovation of display technology, there are more and more types of display screens, and different types of display products are also used in different industry terminals. What are the most fundamental differences between TFT color monitors and monochrome screens? Today LEADTEK is going to tell you about it.

1. TFT color monitor and monochrome TFT display work differently

(1) Monochrome TFT display screen

The working reasons of the color TFT display screen and the monochrome screen are completely different. The monochrome screen is composed of 7 pen segments, and there are many points in a range called pixels. The monochrome screen is composed of fixed size. Point composition These points are arranged in an array; for example, 12864 is composed of horizontal 128 X vertical 64 points. There are many names for monochrome screens, such as pen segment LCD screen, pattern LCD screen, dot matrix screen, broken code screen and so on.

(2) Color TFT display screen

The TFT color monitor fills the liquid crystal material between two parallel plates, and changes the arrangement of the molecules inside the liquid crystal material by voltage, so as to achieve the purpose of shading and transmitting light to display images of different shades and scattered patterns, and as long as a filter layer of three primary colors is added between the two flat plates, a color image can be displayed. Therefore, the working principle of color TFT display screen and monochrome screen is completely different.

2. The application products of TFT color monitor and monochrome TFT display are different

Monochrome TFT display screens are generally used in calculators, watches, remote controls, telephones, etc., while TFT color screens are widely used in handheld terminals, high-end mobile phones, smart homes, Internet of Things equipment, health care, artificial intelligence, video phones, walkie-talkies, etc., and more and more terminal products will be more inclined to choose color TFT display screens as display devices for terminal products.

3. The price of TFT color monitor and monochrome TFT display is different

The TFT color screen is more expensive than the monochrome TFT display screen, because the raw materials and production processes are different, and the color TFT display screen has higher requirements for raw materials, and the processing technology is also very complicated, the cost is higher, and the performance of the product and It is also more popular among people. Monochromatic TFT display screens generally have the problem of high MOQ. Because of their low price, monochrome TFT display screen manufacturers generally increase the MOQ.

Color TFT display screen and monochrome screen are currently the two most common types of display screens on the market. There is no one better, only which type of display is more suitable. Both TFT color monitors and monochrome screens have their own advantages and disadvantages. It is good for everyone to be rational in the selection of models.
