I often see people online asking about the difference between LCD and LED displays. Here, I will provide a comprehensive explanation of the difference between LCD and LED? Are the LED backlight energy-saving and environmental protection promoted by the manufacturer all gimmicks? Is there really such a big difference between LED and LCD? Please follow Afei and help you unravel the mystery of the difference between LEDs and LCDs. Let’s answer in multiple small points below.

ONE、 What is LCD?
LCD is a liquid crystal display screen
The full name of Display, mainly including TFT, UFB, TFD, STN and other types of LCD displays, cannot locate the program input point on the Dynamic-link library.
The commonly used laptop LCD screen is TFT. TFT (Thin Film Transistor) refers to a thin film transistor, where each LCD pixel is driven by a thin film transistor integrated behind the pixel, enabling high-speed, high brightness, and high contrast display of screen information. It is currently one of the best LCD color display devices and the mainstream display device on laptops and desktops. Compared with STN, TFT has excellent color saturation, restoration ability, and higher contrast. It can still be seen very clearly in the sun, but the disadvantage is that it consumes more power and has a higher cost.
Two、 What is LED?
LED is a light emitting diode
The English abbreviation for Diode. LED applications can be divided into two categories: first, LED display screens; The second is the application of LED single tube, including backlight LED, infrared LED, etc. As for LED display screens, China’s design and production technology level is basically in sync with international standards. LED display screen is a computer configuration sheet with a display unit of 5000 yuan, consisting of LED arrays. It adopts low voltage scanning drive and has the characteristics of low power consumption, long service life, low cost, high brightness, few faults, large viewing angle, and long visual distance.
Three、 The difference between LCD and LED
Compared to LCD displays, LED displays have advantages in brightness, power consumption, viewing angle, and refresh rate, which have been removed from the navigation of this webpage. By utilizing LED technology, it is possible to manufacture displays that are thinner, brighter, and clearer than LCDs.
1. The power consumption ratio of LED to LCD is approximately 1:10, making LED more energy-efficient.
2. LED has a higher refresh rate and better performance in video.
LED provides a wide viewing angle of up to 160 °, which can display various text, numbers, color images, and animation information. It can play color video signals such as TV, video, VCD, DVD, etc.
Four. The individual element reaction speed of LED display screens is 1000 times that of LCD LCD screens, and they can be viewed without error under strong light, and can adapt to low temperatures of -40 degrees Celsius.
Simply put, 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 diodes.
Dear friends, now you should understand the difference between LCD and LED! So everyone will definitely say that LED is so good, then I must buy an LED display screen! However, the focus of this article has also come to this: the current LED display screens on the market are not truly LED display screens, but rather LED backlight LCD displays. LCD panels are still traditional LCD displays, and in a sense, this is somewhat deceptive! Samsung, a South Korean company, was once found by the British Advertising Association to have violated the country’s advertising laws because its “LEDTV” LCD TV was suspected of misleading consumers. For liquid crystal displays, the most important key is their LCD panel and backlight type. However, the LCD panels on the market generally use TFT panels, which are the same. The difference between LED and LCD is only their backlight type: LED backlight and CCFL backlight (also known as fluorescent lamps), which are diodes and cold cathode lamps, respectively.
The difference between LED and LCD displays:
LED backlight: Power saving (30%~50% less than CCFL), high price, high brightness and saturation.
CCFL backlight: Compared to LED backlight, it consumes a lot of power (still much less than CRT) and is cheaper.
Screen difference: LED backlight has a bright color and high saturation (CCFL and LED have different natural light sources).
How to distinguish: LED backlight will emphasize LED TV, but what is not emphasized is CCFL LCD TV
There are still real LED TVs on the market (which do not rely on backlight and emit light actively), both SONY and Samgsung, but their panels are currently below 11 inches and are very expensive. TVs like SONY’s 11 inch AMOLED are priced at around rmB18000, belonging to the high-end market, so there are very few on the market. Under general naked eye observation, the color difference between LCD screens and LED screens is not significant. If you only pay a disproportionate monetary price for the LED name, it is really unnecessary. If you don’t think the price is much, then there’s no need to read this article at all. That’s all for now. I believe friends who have read this article have a deeper understanding of the difference between LCD and LED displays. Thank you to visit our website!
