In recent years, with the gradual maturity of small-spacing LED display technology and market, its application in the field of indoor large-screen splicing is more and more common.In particular, with the rapid development of smart city and security industry, the demand for indoor large-screen is increasing in all cities, and the small-spacing LED products become very popular.Although the current price of small spacing products is relatively high, mainly in the middle and high-end market, the high-speed growth momentum of small spacing and the gradual decline in price still bring great pressure to the traditional indoor large-screen splicing products LCD and DLP.Small spacing LED, LCD, DLP products are the characteristics of what?

1. Small spacing LED display: small spacing LED display is very eye-catching in display.Due to the fundamental differences in luminous principle and structure, small spacing LED products can not only realize seamless Mosaic, but also have a wide color range and excellent color performance, which are not comparable to DLP and LCD, and have fast reaction speed, no duplication, shadow and other problems, almost a rewrite of the previous indoor large screen.

2. DLP splicing screen: DLP presents a stable performance.In the joint gap, mirror reflection, better than LCD, but also can not be compared with small spacing;And in the resolution, heat generation, than LCD, but also better than small spacing.Overall, DLP overall performance "mean," in addition to brightness bottom, basic performance good.

Iii. LCD Mosaic screen: the advantages and disadvantages of LCD are also obvious.The biggest disadvantage is that the joint gap is too large. Even the 1.8mm joint is still visible to the naked eye, which has an impact on the overall visual performance.Second, the picture is affected by external light, easy to reflect the problem has to be solved.However, it still has great advantages in terms of resolution, heat generation and maintenance, as well as low requirement for brightness in indoor display, low price and low maintenance cost, and LCD still has obvious advantages in indoor display, making it a mainstay in the large-screen splicing market.

Over the past two years, small-spacing LED display products have been widely popular in the high-end and large-screen field. They are the first choice in various kinds of summits, on-site show at conferences, large command centers and other fields, and even begin to enter cinemas as movie screens.These are undoubtedly built on the display effect of small spacing products, such as good image integrity and strong color expression. However, before we get excited about this, we still need to focus on the application of small spacing LED display in indoor areas, which is also obviously flawed.

1. Brightness: almost free from the influence of external light such as sunlight and lighting, led display becomes the dominant position in the field of outdoor. However, if such features are put indoors, it will face the embarrassment of excessive brightness.Especially in the field of security monitoring, the workers need to face the screen for a long time, and the excessive brightness is not a good visual experience.

2, stability, for the traditional LED display, light death rate is under control in the one over ten thousand, but for high density small spacing screen, one over ten thousand probability apparently can‘t meet the demand of the picture, a lower death rate of light become inevitable requirement, with small spacing more applications in the field of high-end, more strict with the quality.

3. Cost: the purchase cost of small spacing itself is higher than that of LCD, while the cooling cost and power consumption cost of LED display are higher than that of LCD and DLP. The superposition of two aspects makes the overall use cost remain high, making the small spacing LED screen enter the low-end market with huge demand greater resistance.

Although there are still some problems in the small spacing LED display, with the continuous improvement of LED display technology, I believe these problems can be solved well.In recent years, the small spacing LED display is constantly adapting to the needs of indoor applications, which greatly improves the brightness and stability, and the product price is relatively close to the public, so it is no longer unattainable.

Have seen the comparison analysis above, in the face of LED display screen, LCD LCD screen, DLP screen display screen wall, which should choose, I believe we must have had it.
