Compared with lcd display, led has more advantages in brightness, power consumption, visual angle and refresh rate than lcd display. Using led technology, you can make thinner, brighter and clearer displays than lcd.
1:The power consumption of led and lcd is about 1:10, led is more energy-efficient.
2: Led has higher refresh rates and better performance in video.
3: Led offers a 160° wide view of text, numbers, color images and animations. It can play tv, video, vcd, dvd and other color video signals.
4:Led screen reacts 1000 times faster than the lcd screen, can be looked after under strong light, and adapts to temperatures of minus 40 degrees.
To put it simply, lcd and led are two different display technologies. Lcd is a display screen composed of liquid crystals, while led is a display screen composed of light-emitting diode (LED). Friends, you should understand the difference between lcd and led by now!
Then you will say that led is so good, then I must buy led display screen! However, the focus of this paper is here: at present, the led display screen is not the real led display screen, to be exact, the led backlit liquid crystal display, the liquid crystal panel is still the traditional lcd display screen, in a sense, this more or less contains the nature of fraud! South Korea's Samsung company has been convicted by the British Advertising Association of violating the country's advertising law because its "ledtv" LCD TV misleads consumers. For LCD, the most important key is its LCD panel and backlight type, while the LCD panel on the market generally adopts tft panel, which is the same. The difference between led and lcd is only that their backlight types are different: led backlight and ccfl backlight (that is, fluorescent lamp), diode and cold cathode lamp respectively.
