In today's display technology, LCD screen and LED screen is our common two screen types, they each have unique features and advantages, then which is better? LCF‘s editor will be in this article from the display principle and technical characteristics to analyze and compare.

LCD screen (Liquid Crystal Display)

LCD screen is through the arrangement of liquid crystal molecules change to control the light through and blocking, so as to realize the image display. It usually requires a backlight to provide light, and common backlight sources are cold cathode fluorescent tubes (CCFL) and light-emitting diodes (LED).

Pros:

Mature technology, relatively low cost, and a certain advantage in price, which makes it widely used in the market, especially in low-end and mid-range electronic products are more common.

Color performance is more accurate, for some of the higher requirements for color accuracy in the professional field, such as graphic design, photography post, etc., LCD screen can provide more reliable color reproduction.

Disadvantages:

Response time is relatively long, and may appear to drag when switching screens quickly, which may affect the experience for gamers watching high-speed movement or performing fast operations.

The contrast ratio is relatively low, especially when compared to LED screens, the black performance is not deep enough, and the layering and three-dimensionality of the screen may be slightly inferior.

Due to the need for backlighting, the overall structure is relatively thick, which is gradually becoming a limiting factor in the pursuit of thin and light design electronic products.

 LED Screen (Light Emitting Diode)

An LED screen is an array of individual light emitting diodes that display images by controlling the light emitted by each diode. It can be categorized into two types of backlighting: straight down and side entry.

Advantages:

With excellent contrast ratio, it can present deep black and bright white, with a stronger sense of hierarchy and three-dimensionality of the picture, and a more stunning visual effect.

Short response time, able to quickly switch the screen, smoother performance in the display of dynamic images, almost no drag phenomenon, ideal for watching action movies and games and other high-speed dynamic scenes.

Energy-saving effect is remarkable, LED diode light-emitting efficiency is high, compared with the backlight of the LCD screen, can consume less power, which for the long-term use of electronic equipment, not only can reduce energy consumption, but also reduce the pressure of heat dissipation, to extend the life of the equipment.

 The structure is thinner and lighter, which is conducive to the thin and light design of electronic products, such as smart phones and tablet PCs nowadays, more and more LED screens are used, which makes the equipment more portable and beautiful.

Disadvantages:

Relatively high cost, especially for high-quality LED display, which makes it limited in some price-sensitive markets or products.

There may be a “strobe” problem, although modern technology is constantly improving, but some low-quality LED screen at low brightness may appear strobe phenomenon, which has a certain impact on eye health. However, through the use of appropriate dimming technology and select high-quality products, this problem can be alleviated to a certain extent.

The above is LCF's editorial to everyone to organize out about the LED display and LCD display display principle and technical characteristics of the difference, I hope to be helpful to everyone, at the same time, welcome to add or correct. LCF is a collection of R & D, intellectual, sales, operation, service in one of the national speciality and speciality of the small giant enterprises, national high-tech enterprises.
