Both LED display and LCD display are commonly used types of screens in daily life. Some users do not know which LED display or LCD display is better when purchasing? What are the differences? Today, the editor of Liancheng will introduce the difference between LED display and LCD display in detail and which is better between LED and LCD display? For your reference.

1. Introduction of LED display and LCD display

(1) LED display

LED display is the English abbreviation of Light Emitting Diode. LED applications can be divided into two categories: one is LED display. The second is LED single-tube applications, including backlight LEDs, infrared LEDs, etc., which are driven by low-voltage scanning and have the characteristics of low power consumption, long service life, low cost, high brightness, few failures, large viewing angle, and long visual distance. .

(2)LCD display

The LCD display screen is the liquid crystal display screen. There are mainly TFT, UFB, TFD, STN and other types of liquid crystal display screens. The program input point cannot be located on the dynamic link library. LCD can display screen information at high speed, high brightness and high contrast, with 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 energy.


2.the difference between LCD screen and LED screen

(1)Display technology is different

LCD: A display screen composed of liquid crystals.

LED: A display screen consisting of light-emitting diodes.

(2)The display effect is different

LCD: Due to the backlight layer, it emits light by refracting light, the color saturation is not so high, the display effect is more natural, and it is not easy to be tired after long-term viewing.

LED: It can emit light by itself, and each pixel can project the light of three primary colors of red, green and blue, so the display effect is more vivid and full.

(3)Different thickness

LCD: Thicker, due to the presence of the backlight layer and the liquid crystal layer, the thickness will be thicker than OLED.

LED: Light and thin, LED is very easy to make mobile phones thin, and it also provides the possibility for the emergence of bendable and foldable screens in the future.

(4)Different power consumption

LCD: Turning on means that the entire backlight layer is turned on, and it can only be fully turned on or turned off, and the power consumption is high.

LED: Each pixel works independently and can light up some pixels individually, so the power consumption of the LED will be lower.

(5)Screen life varies

LCD: Inorganic materials are used, which have a slow aging rate and a long life.

LED: Using organic materials, the life of the LED screen is not as good as that of the LCD screen.

(6)Differences in use

The LCD screen is suitable for use in monitoring display, small and medium-sized conferences, exhibition halls and other occasions. The LCD screen has become the main product of video surveillance display with the characteristics of high definition, good stability and 24-hour continuous boot, because in the monitoring room, almost all of them run continuously throughout the year, and only industrial-grade panels such as LCD screens can It can meet the needs, and can clearly display the pictures taken by the monitoring, and its after-sales rate is extremely low, which can reach a continuous running time of 200,000 hours, which is very suitable for some occasions with high safety requirements.

In addition, in some small and medium-sized conference rooms or exhibition halls of some enterprises, LCD screens are used more for long-term viewing due to their high-definition characteristics. For example, 9 screens are used to create a large display screen of about 150 inches for meetings and exhibitions. The company's product information and other content can clearly display all the content.

LED screen is suitable for use in advertising, text display, large-scale conferences and other occasions. The biggest advantage of the LED screen is that it has no seams, so it is very suitable for full-screen display. It is mostly used in outdoor publicity occasions, used to play video advertisements, etc., as well as text content display in some stores, information content in public places such as stations It is used to display text and numbers, etc., and in some large-scale lecture halls, product launches and other occasions, due to the long viewing distance, more LED screens are used.

2. Which is better, LED display or LCD display

Compared with LCD displays, LED displays have more advantages in terms of brightness, power consumption, viewing angle and refresh rate. Using LED technology, it is possible to make displays that are thinner, brighter, and sharper than LCDs.

(1)The power consumption ratio of LED to LCD is about 1:10, and LED is more energy efficient.

(2)LED has a higher refresh rate and has better performance in video.

(3)The LED provides a wide viewing angle of 160°, which can display various characters, numbers, color images and animation information, and can play color video signals such as TV, video, VCD, DVD, etc.

(4)The reaction speed of a single element of the LED display screen is 1000 times that of the LCD liquid crystal screen.
