The Advantage of LCD AD DisplayTime:October 10th, 2013
1. Not blink, do not hurt the eyes
Because the LCD each point on a received signal has maintained that the color and brightness, constant light, rather than as a cathode ray tube display (CRT) as the need to constantly refresh the highlights. Therefore, lcd ad display high quality and absolutely not blink, to minimize eyestrain.
2. No electromagnetic radiation
Conventional monitor display material is phosphor, the phosphor by electron beam strikes the display, the electron beam on an instant hit phosphors will produce a strong electromagnetic radiation, although there are many display products in dealing with the issue of radiation were compared effective treatment, as much as possible to minimize the amount of the radiation, it is difficult to completely eliminate. Relatively speaking, LCDs in preventing radiation has inherent advantages, because it simply does not exist radiation. Preventive aspects of electromagnetic waves, LCD monitors also have their own unique advantages, it uses a strict sealing technology will come from a small amount of electromagnetic drive circuit enclosed in the display, while the ordinary display needs to dissipate heat must be possible to make internal circuit contact with air, so that the internal circuit of the electromagnetic wave generated will be a large number of outwardly outwardly "leak."
3. Visual area
For the same size display, the LCD viewing area to be larger. LCD display diagonal viewing area is saying the same size. CRT cathode ray tube display front panel is surrounded by a border of an inch or so can not be used for display. The initial application of a wide range of LCD monitors can not display as delicate character, usually used in electronic watches, calculators. With LCD technology continues to evolve and progress, character display starts up fine, but also supports basic color display, and gradually for LCD TVs, LCD monitors cameras, handheld game consoles. And the subsequent emergence of DSTN and TFT were widely made ??into a computer LCD device, DSTN LCD screen for early laptops ; TFT is applied both on a laptop ( most laptops now use TFT display ), but also for mainstream desktop monitor. Screen effect compared with conventional displays, liquid crystal displays outset use plain flat glass, the display is a plane at right angles, people have a refreshing feeling. And LCD monitor is easier to achieve in a small area of ??the screen resolution, for example, 17-inch LCD monitor will be able to achieve a good 1280 × 1024 resolution, and are usually 18 inches CRT color monitor used on more than 1280 × 1024 resolution screen effect is not completely satisfactory
4. Digital interfaces can be used directly
Liquid crystal displays are digital, not analog color display cathode ray tube interface. In other words, the use of LCD monitors, graphics cards may not need as usual the digital signal into an analog signal is output again.
5. "Body" proportioned compact
Conventional cathode ray tube display, always dragged behind a bulky ray tube. LCD monitors exceeded this limit, giving a new feeling. Traditional monitors by emitting an electron beam electron gun to the screen, so the picture tube neck can not do very short, when the screen is also bound to increase the volume of the entire display increases. The LCD display on the display screen of the liquid crystal molecules in the state of electrode control as to display the object, even if the screen to increase, its volume does not increase in proportion to, and in weight lighter than the conventional displays.
6. Small power consumption
Traditional monitors the internal circuit by a number of these circuits driving the cathode ray tube operation, the need to consume a lot of power, and with the constant increase of the volume, power consumption of its internal circuitry will definitely increases. In contrast, the liquid crystal display in its internal power consumption of the main electrode and a driver IC, and therefore also much less power than conventional displays.
