Difference between LCD and LED liquid crystal display
December 20, 2022
LED displays compared to LCD displays, LED in terms of brightness, power consumption, viewing angle and refresh rate, have more advantages have been eliminated to the navigation of this page. Using LED technology, you can create a thinner, brighter and clearer display than LCD.
1, LED and LCD power consumption ratio of about 1:10, LED is more energy efficient.
2, LED has a higher refresh rate and better performance in terms of video.
3, LED provides a wide viewing angle of up to 160 °, can display a variety of text, digital, color images and animation information, can play TV, video, VCD, DVD and other color video signals.
4, LED display of the individual elements of the response speed is 1000 times faster than LCD LCD, in bright light can also be seen, and adapt to the low temperature of minus 40 degrees.
Simply put, LCD and LED are two different display technologies, LCD is a display composed of liquid crystals, while LED is a display composed of light-emitting diodes.
Dear friends, now you should understand the difference between lcd and led! Then you will say LED so good, then I must buy LED display! However, the focus of this article also came: the LED display currently on the market is not the true sense of the LED display, to be precise, is the LED backlit LCD, LCD panel is still the traditional LCD display, in a sense, this more or less contains the nature of fraud! South Korea's Samsung has been judged by the British Advertising Association organization for violating the country's advertising law, the reason is that its "LEDTV" LCD TV has the suspicion of misleading consumers. For LCD monitors, the most important key is its LCD panel and backlight type, and the LCD panel of the market monitors generally use TFT panels, is the same, the difference between LED and LCD is simply that their backlight type is not the same: LED backlight and CCFL backlight (also known as fluorescent lamps), respectively, diodes and cold cathode lamps.
The difference between LED displays and LCD displays:
LED backlight: power saving (compared to CCFL power saving 30% ~ 50%), high price, high vividness and saturation.
CCFL backlight: relative to the LED backlight power consumption (still much more power-efficient than CRT), cheap.
Screen difference: LED backlight color is more vivid, high saturation (CCFL and LED born light source is not the same).
How to distinguish: LED backlighting will be particularly stressed is LED TV, not stressed is CCFL LCD TV
There are still real LED TVs on the market (not by backlight, will actively light), SONY and Samgsung have, but their panels are currently below 11 inches, and very expensive, like SONY 11-inch AMOLED TVs cost about rmB18000, belonging to the high-end market, so few on the market. Let's take a look at the difference between lcd and led the actual picture comparison chart, the following 2 laptop display: the left for the CCFL backlight type LCD, the right for the LED backlight type LCD, respectively, red, green, blue three colors under the contrast as shown below:
As you can see from the chart, the color difference between LCD screens and LED screens is not that great under general observation by the naked eye. If you pay a monetary price that is not commensurate with it just for the name LED, it is really not necessary.
