In today's display technology field, LED display and liquid crystal display are the two most common products. Although they are both devices used to display images and videos, there are clear differences between them. LCF editor will introduce the difference between LED display and LCD display in detail, including working principle, performance characteristics and application scenarios.

First, LED display

1. How it works

LED display is a display with light emitting diode (LED) as the display element. The basic unit of the LED display is the LED lamp bead, which displays different images and text by controlling the on-off state of each lamp bead. LED display can be made modular, by combining multiple modules, can be composed of different sizes and shapes of the display.

2. Performance characteristics

LED display has the following advantages:

(1) High brightness: The brightness of the LED display is high, which can maintain clarity in a strong light environment, while providing enough lighting in a dark environment.

(2) Long life: the life of LED lamp beads is more than 50,000 hours, reducing the number of maintenance and replacement costs.

(3) Fast response speed: The LED display has a high refresh rate and can quickly display dynamic images and videos.

(4) Rich color: LED display can display full color images, high color reproduction.

3. Application scenario

LED display is widely used in outdoor advertising, public information release, sports venues, stage background, exhibition and other fields. Due to its high brightness and high reliability, LED displays have also become the first choice for information release in many important areas such as military, transportation, and public safety.

Second, liquid crystal display screen

1. How it works

A liquid crystal display is a display that uses liquid crystal molecules to control the propagation of light to display images. The basic unit of a liquid crystal display screen is a liquid crystal molecule, which changes its arrangement under the action of an electric field, thus affecting the propagation of light. Liquid crystal display requires a backlight source to provide lighting, usually using CCFL (cold cathode fluorescent lamp) as a backlight source.

2. Performance characteristics

LCD screen has the following advantages:

(1) Thin thickness: The thickness of the LCD screen is thin, and it can be made into a portable mobile device.

(2) Power saving: The LCD has a low power consumption, which can extend the battery life.

(3) Small radiation: the radiation of the LCD screen is low, which is less harmful to the eyes and the body.

3. Application scenario

LCD screen is widely used in TV, computer, mobile phone and other electronic products. Due to its thin thickness, power saving and other characteristics, liquid crystal displays have also become the main display components of many mobile devices such as laptops and tablets.

Third, summary

LED display and LCD display have their own advantages and application scenarios. LED display is suitable for occasions requiring high brightness, long life, fast response and full color, such as outdoor advertising, stage background, etc. The LCD screen is suitable for occasions that require thin, light, power saving and low radiation, such as mobile devices, laptops and so on. When choosing the right display device, it is necessary to decide which type of display to use according to the actual needs.
