What are the advantages of TFT LCD screen? --TFT LCD screen manufacturer
TFT LCD screen has a semiconductor switch for each pixel, and its processing technology is similar to that of LSI. Because each pixel can be directly controlled by a point pulse, each node is relatively independent and can be controlled continuously. This design not only improves the reaction speed of the display screen, but also can accurately control the gray level of the display, so the color of TFT liquid crystal is more realistic. So what are the advantages of TFT LCD?
乐发II500I. High display quality
乐发II500Because each point of TFT LCD always keeps that color and brightness after receiving the signal, and emits constant light, unlike the cathode ray tube display (CRT), it needs to refresh the highlights constantly. Therefore, the TFT LCD screen has high quality and does not flicker, which reduces eye fatigue to a very low level.
乐发II500II. Large visible area
For the same size display screen, the visual area of TFT LCD screen is larger. The visual area of TFT LCD screen is the same as its diagonal size. The front panel of the CRT display screen is surrounded by an inch or so of frame, which cannot be used for display.
乐发II5003. Wide range of applications
乐发II500Initial LCD screens were usually used in electronic watches and calculators because they could not display delicate characters. With the continuous development and progress of liquid crystal display technology, character display began to be delicate, but also to support the basic color display, and gradually used in liquid crystal television, camera LCD.
乐发II500Then DSTN and TFT were widely used as LCD devices in computers. DSTN LCD screens were used in early notebook computers. TFT was used in both notebook computers (most notebook computers now use TFT screens) and mainstream desktop displays.
4. No electromagnetic radiation
The display material of traditional display screen is phosphor. It is shown by the impact of electron beam on phosphor that the strong electromagnetic radiation will be produced when the electron beam hits the phosphor. Although many display screen products have dealt with the radiation problem effectively and reduced the radiation to a very low level as far as possible, it is difficult to eliminate it completely. Relatively speaking, TFT LCD displays have innate advantages in preventing radiation, because there is no radiation at all.
乐发II500In the aspect of electromagnetic wave prevention, TFT LCD screen also has its own unique advantages. It uses strict sealing technology to enclose a small amount of electromagnetic wave from driving circuit in the display. In order to radiate heat, ordinary display must contact the internal circuit with air as much as possible, so that the electromagnetic wave generated by the internal circuit will leak out in large quantities.
V. Digital Interface
TFT LCD screens are digital, unlike the analog interface used in CRT color display. That is to say, using TFT LCD screen, graphics cards no longer need to convert digital signals into analog signals and output them as usual. In theory, this will make the color more accurate and perfect.
乐发II5006. "Body" is symmetrical and compact
乐发II500Traditional cathode ray tube displays always have a bulky ray tube behind them. TFT LCD screen breaks through this limitation and gives people a new feeling. The traditional display screen transmits electron beams to the screen, so the neck of the picture tube can not be made very short. When the screen increases, it will inevitably increase the volume of the whole display.
The TFT LCD screen controls the state of liquid crystal molecules through the electrodes on the display screen. Even if the screen is enlarged, its volume will not increase proportionally, and its weight is much lighter than that of the traditional display with the same display area.
乐发II5007. Good picture effect
Compared with the traditional display screen, TFT LCD screen uses pure flat glass plate at the beginning. Its display effect is flat right angle, which makes people have a refreshing feeling. It is also easier for LCD to achieve high resolution on small screen. For example, 17 inch LCD can achieve 1280 *1024 resolution very well, but the effect of using 1280 *1024 resolution on 18 inch CRT color display is not completely satisfactory.
乐发II5008. Low Power Consumption
The traditional display screen is composed of many circuits. These circuits drive the CRT to work. They need to consume a lot of power. And with the increasing volume, the power consumed by the internal circuit will certainly increase. In contrast, the power consumption of TFT LCD is mainly consumed by its internal electrodes and driving IC, so the power consumption is much less than that of traditional displays.
