Led display lcd LCD screen and DLP splicing screen in the end how to choose?

In recent years, with the gradual maturity of small-pitch led display technology and market, its application in the field of indoor led display splicing is more and more common. Especially in the current rapid development of smart cities and security industries, the demand for indoor large screens in various cities is increasing, and small-pitch LED products are also popular. Although the current price of small-pitch products is relatively high, mainly concentrated in the middle and high-end market, but under the trend of high-speed growth of small pitch and the gradual decline of prices, it still brings a lot of LCD and DLP to the traditional indoor LED display splicing products. pressure. How to choose led display, lcd LCD screen and DLP splicing screen?
Small pitch led display
The small-pitch led display is very eye-catching in terms of display performance. Due to the fundamental differences in illumination principle and structure, small-pitch LED products can not only achieve seamless splicing, but also have a wide color gamut and excellent color performance. These are not comparable to DLP and LCD, and the response speed is fast. The problems of ghosting and smear are almost a rewrite of the indoor LED display.
DLP splicing screen
DLP is stable. In terms of splicing gaps and specular reflections, it performs better than LCDs, but it cannot be compared with small pitches. In terms of resolution and heat generation, it is better than liquid crystal display, but it is better than small pitch. On the whole, DLP's overall performance is "moderate", and it basically performs well except for the bottom of the brightness.
LCD splicing screen
The advantages and disadvantages of LCD are also obvious. The biggest drawback is that the splicing gap is too large, even the 1.8 mm splicing seam is also visible to the naked eye, which has an impact on the overall visual performance. Secondly, the picture is greatly affected by external light, and the problem of easy reflection is still to be solved. However, it still has a large advantage in terms of resolution, heat generation, maintenance, etc., and the indoor display does not require high brightness, and the price is low, the maintenance cost is not high, etc., the advantage of LCD in indoor display is still obvious, becoming The mainstay in the big screen splicing market.
In the past two years, small-pitch led display products have become very popular in the high-end large-screen field, whether it is displayed at various summits, conferences, or in large-scale command centers, and even began to enter the cinema as a movie screen. And exist. These are undoubtedly based on the display performance of small-pitch products with good picture integrity and strong color expression. However, before we are excited about this, we still need to focus on the application of small-pitch LED display in indoor applications. .
1, brightness
Almost without the influence of external light such as sunlight and light, the LED display becomes the dominant player in the outdoor field, and when such characteristics are placed indoors, the brightness is too high. Especially in the field of security monitoring, the staff needs 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, the dead light rate is generally controlled below one ten thousandth, but for high-density small-pitch screens, one-tenth of the probability is obviously not enough to meet the screen demand, and the lower dead light rate becomes inevitable. Requirements, plus small spacing and more applications in the high-end field, the quality requirements are even more stringent.
3. Cost
The purchase cost of the small pitch itself is higher than that of the LCD, and the heat dissipation cost and the electricity cost of the LED display are higher than those of the LCD and the DLP. The superposition of the two aspects makes the overall use cost high, and the small pitch led display The screen enters the middle and low end of the huge demand market with greater resistance.

Jin Yuankang Aluminum Alloy Plating, can be obtained on the product decoration and protection of a variety of functional surface layer, but also to repair the wear and processing errors of the workpiece. The aluminum alloy can obviously improve the physical and chemical properties of the surface of the aluminum alloy, improve the electrical conductivity of the surface or the electric contact part, improve the solderability of the aluminum alloy, improve the abrasion resistance and improve the decorative property.
