New bar technology tells you the fundamental difference between LED display and LCD screen

Now people are in pursuit of a kind of enjoyment, whether it is the spirit or material, television, computer and other indispensable equipment is important for people, dazzling products in the market, often confusing, such as the common LCD and led differences , people feel very confused, Today I will explain to you the difference between LCD and led and their respective characteristics .

(On the left is the LCD display, the right is the LED display)

The principle of LCD and LED

LCD is the abbreviation of Liquidcrystaldisplay, its structure is mainly in two parallel glass in the liquid crystal, in the middle of the parallel two pieces of glass there are many vertical and horizontal small electrical lines , through the power or not to control rod The crystal molecule changes direction, and the light is refracted out to produce a picture.

LED is the abbreviation of Light-emittingdiode, it works in the PN junction of some semiconductor materials, the injected minority carrier and the majority of carrier compound will be the excess energy in the form of light release, so that the direct conversion of electrical energy into energy; PN Junction Plus reverse voltage, few carriers difficult to inject, then do not emit light. The two-pole diode, which is produced by the injection-type electroluminescence principle, is known as the LED.

Conclusion: Thebiggest difference between LCD and led is the application of two different display technology , LCD is composed of liquid crystal display, and LED is composed of light-emitting diode display, the main differences are derived from here analysis.

(LED display more realistic, more color sense)

The difference between LCD and LED

first, brightness , LED display single element reaction speed is LCD LCD screen 1000 times times, and its brightness relative to LCD LCD screen is also more advantageous, LED display in the strong light can also be looked after, and adapt to the low temperature of –40.

second, power consumption, power consumption is one of the most concern, led power consumption and LCD compared to the ratio of about 10:1, in this respect, LED has a great advantage.

third, the visual angle , LCD viewer angle limit is very large, this is a very busy people headache problem, as long as the deviation from the angle slightly larger, you can not see the original color, and even see nothing, and led can provide a 160 ° angle of view , the advantage is great.

The refresh rate , led using electric energy into light energy, using injection principle, so its refresh rate is higher, and then in the View screen processing better.

Fifth, contrast , the currently known high-contrast LCD display is 350:1, but in many cases, can not meet a variety of needs, but LED display could reach a higher, more extensive use.

(The main difference between the two is the different display technology)

VI, Appearance , led using light-emitting diode-based, relative to the LCD, its display can be made thinner.

seventh, the use of the scope of the LED display wider than the LCD display, it can display a variety of text, numbers, color images and animation information, but also can play TV, video, VCD,DVD and other color video signals, More importantly, multiple displays can be used to broadcast on the Internet.

Eighth, the service life, LED display can generally support about 100,000 hours, under normal circumstances, can be used for decades, and LCD is much less.

nineth, Color ,LED screen than the color of the LCD screen to be more real, this is because LED TV (fine domain name) color gamut than LCD much more.

Through the author of this in-depth explanation of the difference between LCD and led , I believe we also have a more in-depth understanding, in the choice, should not hesitate it.
