Learn about information about small LED display screens
LED display technology is widely used, in the past, we in the life of the common LED display is more P3 ~ P10 large spacing LED display, and in recent years, small LED display has quietly rise.
Small LED display with better performance, smaller size, gradually favored by the market, we together through this article to understand why small LED display is so popular.
What is small LED display
Usually when we mention small LED display, the definition of small is actually very broad, it is very subjective view, the definition of small is relative, not absolute.
What kind of LED display is small LED display?In the display industry, the mainstream saying is that small LED display contains: small pitch LED display, Mini-LED display and Micro-LED display.
What is small-pitch LED display
Small-pitch LED display is the LED display with pixel pitch less than 2mm, which is usually made by SMD technology or COB technology, and it has excellent performance in picture quality, brightness, color and contrast, etc. Therefore, in high-end occasions, many high-definition LED displays are also used.
Therefore, in the high-end occasions, many high-definition display applications have gradually shifted from OLED to small pitch LED display.
What is Mini-LED display
Mini-LED display is the result of further refinement of the development of small-pitch LED display, its LED size is usually between 100-200 microns, Mini-LED display LED base size is smaller than the small-pitch LED display, and larger than the Micro-LED display.
At present, Mini-LED technology is mostly used in LCD backlighting system, which is widely used in laptop computer display, professional video editing display, and other display applications with high video display requirements due to its low light leakage, high contrast ratio, and vivid and clear images.
What is Micro-LED display
Micro-LED is a LED display assembled by combining LED arrays integrated at high density on a single chip after miniaturizing and matrixing the LEDs.
Micro-LED display technology concept is the LED film, miniaturization, matrix, its LED is less than 50 microns, and can be individually driven light, so Micro-LED display can be used for independent light-emitting flat panel or some flexible display.
The main difference between the three kinds of small LED display
Backlight and self-luminous design
The three kinds of small LED display can be self-luminous, in which Micro-LED display and small-pitch LED display are used in the field of self-luminous LED display, while Mini-LED technology is used in the backlight system of LCD.
Therefore, although Mini-LED technology has high brightness and excellent color gamut, after the LCD backlight system, there will always be some light leakage to the black area, resulting in a loss of brightness.
Therefore, in the application field, the brightness of LCD applied by Mini-LED technology is lower than that of small-pitch LED display and Micro-LED display.
Pixel density and resolution
In terms of pixel density, Micro-LED has the smallest pixel pitch, the pixel density of Micro-LED is much higher than the pixel density of Mini-LED, and the pixel density of Mini-LED is much higher than the pixel density of small-pitch LED.
And Mini-LED technology application of LCD is usually a fixed size screen, the resolution is also fixed, small pitch LED screen and Micro-LED screen support free customization, the larger the size of their LED screen customization, the higher the resolution.
Production
process is the most mature and simple is the small pitch LED display, it is now in the display industry has been in a mature application state, while Micro-LED and Mini-LED are still emerging technologies, the process is not so mature, their production process is more complex.
Especially Micro-LED, its LED pitch is the smallest, the technical difficulty is the biggest, to break through a lot of technical barriers.
Lifespan
The service life of Mini-LED screen is about 55,000 hours, the service life of small-pitch LED display is about 70,000 hours, and the service life of Micro-LED screen is about 100,000 hours.
But Micro-LED screen due to more precise, more likely to suffer impact damage, once the damage occurs, the maintenance cost is more expensive, compared to the small pitch LED display is more durable, and if the damage occurs, the small pitch LED display maintenance costs are less, maintenance is more simple.
Cost
As an emerging technology in the display industry, Micro-LED and Mini-LED represent the top macro display technology, their costs are more expensive, similarly, in the small pitch LED screen, P0.4, P0.6 also represents the top fine LED display, the price is also very expensive.
If it is not particularly professional high-end occasions, choose pixel pitch greater than 0.6mm small LED display may be more in line with your cost budget.
Advantages of small LED display
The ultra-small pitch of small LED display means that the pixel density of the display is extremely high, and the details of the picture are extremely rich. small LED display also has a wide color gamut and high contrast ratio, with excellent image quality, which makes it suitable for a variety of professional and high-end occasions.
And small LED display can be joint interactive design, let the audience and LED display for interaction, increase the fun of the screen.
In the future, small LED displays will be indispensable in the field of science and technology, and some very professional and high-tech fields need this kind of fine display.
Comparison of small LED display and OLED, LCD
Since 2015, market demand and technological advances have pushed the rapid development of small LED display, before that, most of the indoor displays on the market are LCD and OLED, and LED screens are more used for outdoor large-scale displays, small LED The rapid development of small LED display has allowed it to start competing with OLED and LCD in the indoor display market.
The service life of small LED display is about ten times more than that of OLED and LCD, and the cost of small LED display is much lower than that of OLED; OLED screen always has the risk of burn-in, while small LED display does not have the risk of burn-in; OLED and LCD have very low brightness, while small LED display always meets the display requirements of various environments with its high brightness.
Small LED display perfectly overcomes the shortcomings of LCD and OLED, therefore, it has achieved good results in the market competition with the two.
