In recent years, with the gradual maturity of the technology and market of small pitch led display, its application in the field of indoor led display splicing is more and more common. Especially with the rapid development of smart cities and security industry, the demand for large indoor screens in all cities is increasing, and small pitch LED products are also becoming popular. Although the price of small pitch products is relatively high at present, mainly concentrated in the middle and high-end markets, under the high-speed growth momentum of small pitch and the trend of gradual price decline, it still brings a lot of pressure to the traditional indoor LED display panel splicing products LCD and DLP. How to choose LED display, LCD screen and DLP splicing screen?

Small pitch led display

The performance of small spacing led display is very eye-catching. Due to the fundamental difference in luminous principle and structure, small pitch LED products can not only achieve seamless splicing, but also have a very wide color gamut and excellent color performance. These are not comparable to DLP and LCD, and they have fast reaction speed, no double shadow, drag shadow and other problems, almost a rewrite of the previous indoor LED display.

DLP splicing screen

DLP was stable. In terms of splicing gap and mirror reflection, it performs better than LCD, but it cannot compare with small spacing; In terms of resolution and heat generation, it is not as good as LCD, but it is also better than small spacing. In a word, DLP's overall performance is "moderate", with good performance except for the lowest brightness.

LCD splicing screen

The advantages and disadvantages of LCD are also obvious. The biggest disadvantage is that the splicing gap is too large. Even the 1.8mm splicing gap is visible to the naked eye, which affects the overall visual performance. Secondly, the picture is greatly affected by external light, and the problem of easy reflection also needs to be solved. However, it still has great advantages in terms of resolution, heat generation, maintenance, etc., and the indoor display does not require high brightness. In addition, the low price and low maintenance cost, LCD still has obvious advantages in indoor display, becoming the mainstay in the large screen splicing market.

In the past two years, small pitch LED display products have been widely welcomed in the high-end large screen field. They are the first choice in various summits, conferences, large command centers and other fields, and even began to enter cinemas as movie screens. These are undoubtedly based on the display effects such as good picture integrity and strong color expression of small pitch products. But before we are excited about this, we still need to focus on the same obvious defects in the indoor application of small pitch led displays.

1. Brightness

Almost free from the influence of sunlight, lighting and other external light, led display has become the leader in the outdoor field. however, if this feature is put indoors, it will face the embarrassment of high brightness. Especially in the field of security monitoring, staff need to face the screen for a long time, and high brightness is not a good visual experience.

2. Stability

For traditional LED displays, the dead light rate is generally controlled below 1/10000, but for high-density small spacing screens, the 1/10000 probability obviously cannot meet the picture requirements, so a lower dead light rate becomes an inevitable requirement. In addition, small spacing is more used in high-end fields, so the quality requirements are more strict.

3. Cost

The purchase cost of small spacing is higher than that of LCD, while the heat dissipation cost and power consumption cost of LED display are higher than that of LCD and DLP. The combination of the two aspects makes the overall use cost of small spacing LED display remain high, making it more difficult for small spacing LED display to enter the middle and low end market with huge demand.
