The difference between LED TV and LCD TV LCD TV and Which led TV is better?
(LCD display on the left, LED display on the right)
1 . What is LEDTV
LED TV is a TV that uses light-emitting diodes as a backlight source. It is still an LCD TV, which is environmentally friendly. Power saving, light and thin TV structure, bright picture quality, uniform screen brightness and longer life of TV screen.
2What is an LCD TV
LCD TVs are also called LCD TVs. The light source emits light, that is, the lamp tube emits light.) The TV with the backlight source becomes the LCD TV, but this name is unscientific and one-sided, because according to the different backlight sources, LED TVs and LCD TVs are both types of LCD TVs. , and the price of this LCD TV is generally cheaper.
3. LEDDifference between TV and LCD TV
The difference between LED TVs and LCD TVs (here only represents CCFL cold light source LCD TVs) is mainly in the backlight source. The former uses LED diodes to emit light, while the latter uses lamps to emit light, which makes LED TVs brighter than traditional LCD TVs. Higher, and the body is thinner and lighter, and the use and use are longer. Although LED TVs are higher than traditional LCD TVs in terms of price, LED TVs are better than traditional LCD TVs in terms of picture quality, energy saving, maintenance and other aspects. Quality is better.
LEDTV and LCDDifference between TV
Working principle:
LED (Light Emitting Diode), namely light-emitting diode, is a semiconductor solid-state light-emitting device, which uses solid-state semiconductor The chip is used as a light-emitting material. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine and cause photon emission to generate light. LEDs can directly emit red, yellow, blue, green, cyan, orange, purple, and white light.
LCD (Liquid Crystal Display), which is a display method by controlling semiconductor light-emitting diodes, its general appearance is composed of many small lights, usually red, which are displayed by the lights on and off. character.
Color Gamut:
The color gamut of LCD is currently 72% to 92%, while the color gamut of LED can reach 118%. LEDs have many advantages, such as high brightness, wide color gamut, fast response, and independent switching. In other words, if the LED backlight replaces the traditional CCFL, the realization of the ultra-wide color gamut will become very easy.

Price:
LED is more than double the price of the same size LCD.
Pros and Cons:
LEDLCD TV Pros:
1. Ultra-wide color gamut, can reach 105% NTSE color gamut, so the color is more vivid.
2. Ultra-thin appearance, the thinnest reaches 1.99 cm, which is more fashionable.
3. Energy saving and environmental protection, the energy consumption is 52% lower than that of the cold cathode backlight source, and there is no mercury pollution of the cold cathode tube.
4. Long lifespan, reaching nearly 100,000 hours, and it can be used for 27 years if it is driven for 10 hours a day.
5. The ultra-high contrast ratio of 100,000:1 can be achieved, and the definition is higher.
LEDLCD TV Disadvantages:
1. The layering and dynamic performance are not satisfactory.
2. The depth of the picture is not obvious.
LCD LCD TV Advantages:
1. High display quality
2. No electromagnetic radiation
3. Wide application range
4. Digital interface
5. Low power consumption
LCD LCD TV disadvantages:
1. The viewing angle of LCD is relatively small compared to CRT monitors.
2. In terms of display response speed, traditional monitors have very good response speed due to their technical advantages.
3. The response time of LCD is relatively long, so the performance in dynamic images is not ideal.
4. Its manufacturing yield is relatively low.
5. Display quality: In theory, LCD can only display 18-bit color (about 262144 colors), but the color depth of CRT is almost infinite.
6. The LCD display is relatively fragile and easily damaged.
