Lcd and led TV that good
LCD liquid crystal display is the abbreviation of Liquid Crystal Display. The structure of the LCD is to place liquid crystals in two parallel glasses. There are many vertical and horizontal small wires in the middle of the two glasses, and the rod crystal molecules are controlled through energization or not. Change direction and refract light to create a picture.
LED is the abbreviation of English light emitting diode (LED), its basic structure is an electroluminescent semiconductor material, placed on a leaded shelf, and then sealed with epoxy resin around to protect the internal core Role, so the LED's seismic performance is good. The difference between the LED liquid crystal and the ordinary liquid crystal is that the light source of the backlight is different. It is said that the life span of the LED is much longer than that of the ordinary fluorescent tube, and the brightness is also much uniform and the price is much more expensive. Compared to common cold cathode fluorescent lamp backlight TFT-LCD liquid crystal, LED backlight is a little good.
1, the uniformity of the backlight is better, there will be no black uneven situation
2, better contrast, led can be turned off under the full black screen backlight, so as to achieve better dynamic contrast
3, the color performance is better, because you can use three-color led backlight, color temperature can be effectively controlled, resulting in more realistic colors and a wider color gamut
4. Since the LED is driven by low voltage, the boost circuit of the cold cathode backlight is omitted and it can be made thinner.
5, if the dynamic led backlight, (the principle is to use two image drivers, one to drive the LCD screen, and the other to the outdoor large-screen led display wall drive led, drive resolution does not need to be too high), 47-inch Led backlight LCD TV can achieve dynamic power consumption, the lowest power consumption can be 10 watts, the maximum brightness is also below 200 watts, while the contrast can exceed 100,000:1, brightness can reach 1000 nits, color gamut 132% NTSC, and then will Pdp is far behind (except for slower response speeds). The difference between led and lcd TV: just the principle of backlight is not the same. The LCD uses a lamp and the LED uses a light emitting diode. It is better to use LED. LED backlight LCD TVs use LED light-emitting diodes as backlight sources, which have five advantages over cold-cathode fluorescent tube backlights:
One, ultra-wide color gamut, can reach 105% NTSE color gamut, so the color is more vivid.
Second, ultra-thin appearance, the thinnest to 1.99 cm, more stylish.
Third, energy conservation and environmental protection, energy consumption 52% lower than the cold cathode backlight, and there is no mercury contamination of the cold cathode tube.
Fourth, long life, reaching nearly 100,000 hours, open 10 hours a day, then you can use 27 years.
Fifth, can achieve ultra-high contrast ratio of 100000:1, higher definition.
