Flat Panel TV Classification Is year 3? 15 International Consumer Rights Day, the recent consumer appliances, especially
TV , Refrigerator, air conditioning and other "large" household appliances even more concerned about the quality. Of course, as businesses have the responsibility to clarify its obligation to the consumer what to sell products with features and characteristics. However, as a wise consumer, if he can have some basic knowledge of home appliances, be able to buy explicit, not JS .
The highest prevalence of large color TV, as home appliances, has been ranked first in all kinds of attention from household appliances. Therefore, we must first look at the concept of flat-panel TVs brief. The so-called flat-panel TV FPD (FlatPanelDisplay), that were flat screen TV, it is relative to the large body of traditional CRT TV to compare in terms of a class of television. Traditional
CRT (Cathode ray tube) television, compared with the thin, light, low power, low radiation, no flicker, enabling health and so on. In recent years, flat-panel television has gradually replaced the CRT to become the first choice for consumers to buy color TV sets.
Flat-panel TVs are classified according to technical system includes the following: LCD
LCD (Liquid Crystal Display), Plasma Display PDP (Plasma DisplayPanel), electroluminescence display O
LED (Organic Light Emitting Display), surface conduction
Electronic Emission Display SED (Surface-conduction Electron-emitterDisplay) and so on. Currently OLED, SED and other technology still remain in the laboratory stage, the current mainstream flat-panel TV market is mainly two types of LCD and plasma.
So, what is LCD TV And plasma TV, what features they have, the following on to answer this question.
LCD TV Used in LCD TV LCD (LiquidCrystal) material is a range of organic compounds between solid and liquid, regular molecular arrangement of features. In the heating mode will show the transparent liquid state, cooling will be presented after the solid state crystal turbidity particles.
LCD TV is a tube through the rear light, and then through a lens and the backlight module Link will be sent to the front of the light source evenly, according to the received video signal, pixel LCD glass layer of liquid crystal molecules will be compared corresponding order, to decide which deflection of light is required or barrier, to form images.
LCD TV through the display electrodes to achieve the state of LC molecules display purposes, to increase and not increase the thickness of the screen, so thin and light portable LCD TV to provide consumers with a wall of the installation, save space. And can provide higher resolution, such as commonly used now on the market for high-definition resolution of 1366 × 768 and 1
920 × 1080 full HD resolution, to meet consumer demand for viewing high-definition video.
Health and environmental protection. LCD TV radiation is small, only a small amount of electromagnetic waves from the driver circuit, as long as the shell can be strictly ruled out electromagnetic waves leaking seal. LCD TV screen flicker does not exist, not easy to cause visual fatigue. In addition, more than the same size LCD TV CRT TV and other technology to lower power consumption of television, and have the advantage of long life.
, Of course, but also see the shortcomings of LCD TVs. As the rotation of liquid crystal molecules take time, that is, response time, thus in a dynamic picture of the performance, there is ghosting. However, in recent years to enhance LCD TV manufacturers to use a refresh rate, etc. to improve this problem.
LCD TV viewing angle, another problem is the limited viewing from the side of the screen image will appear gray, color distortion. However, with advances in LCD technology, this gap is gradually reduced. Currently there are vendors with IPS panels, etc. to enhance viewing angle.
