These three kinds of splicing screens will cost you in the end

163.com | 02/04/2021

In recent years, with the gradual maturity of small-pitch LED display technology and the market, its application in the field of indoor large-screen splicing has become more and more common, especially the wide application of LCD splicing TV walls, which is one of the current rapid developments in smart cities and security industries. Under the circumstance, the demand for large indoor screens in various cities is increasing, and the small-pitch LED products are also popular all the way. Although the current prices of small-pitch products are relatively high, mainly concentrated in the mid-to-high-end market, the rapid growth momentum of small-pitch and the gradual decline in prices still put a lot of pressure on traditional indoor large-screen splicing products LCD and DLP . What are the characteristics of small-pitch LED, LCD, and DLP products?

One. Small pitch LED screen

1. The small-pitch led display is very eye-catching in terms of display performance. Due to the fundamental difference in light-emitting principles and structures, 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 the response speed is fast. Problems such as ghosting and smearing are almost a rewrite of the previous large indoor screens.

2. In recent years, small-pitch LED display products have become popular in the field of high-end large screens, whether they are displayed at various summits, conferences, or in large-scale command centers, they are the first choice, and they have even begun to enter movie theaters. The movie screen exists. These are undoubtedly based on the display effects of small-pitch products such as good picture integrity and strong color expression, but before we are rejoicing, we still need to focus on the indoor application of small-pitch led displays. The same obvious defects , The definition is not as good as LCD.

Two. DLP splicing screen

1. DLP performed smoothly. In terms of splicing gaps and mirror reflection, it performs better than LCD, but it cannot be compared with small pitch. In terms of resolution and heat generation, it is not as good as liquid crystal display, but it is better than small pitch. In summary, DLP's overall performance is "moderate", except for the bottom of the brightness, it basically performs well.

Three. LCD splicing screen

The advantages and disadvantages of LCD are also more obvious. The biggest disadvantage is that the splicing gap is slightly larger, even the 1.7 mm splicing seam is within the visible range of the naked eye, which affects the overall visual performance. Secondly, the picture is greatly affected by external light, and the problem of easy reflection has yet to be solved. However, it still has great advantages in terms of resolution, heat generation, maintenance, etc., and indoor display does not require high brightness, coupled with low price and low maintenance cost, LCD still has more obvious advantages in indoor display. The mainstay in the large-screen splicing market, especially the ultra-narrow-edge LCD splicing screen is more popular with users.

Whether it is a small-pitch LED splicing screen, DLP splicing screen or the current popular LCD splicing screen, there are advantages and disadvantages. Users should pay attention to the use environment, functional requirements and cost budget when choosing. At present, it is the cost-effectiveness of LCD splicing screens. It is because of this that the LCD splicing screen that enters the market is developing rapidly.

1. Brightness

   is almost unaffected by external light such as sunlight, lights, etc., making the LED display the dominant in the outdoor field, and when such features are placed indoors, it will face the embarrassment of excessive brightness. Especially in the field of security monitoring, workers need to face the screen for a long time, too high brightness is not a good visual experience.

2. Stability

   For traditional LED display screens, the dead light rate is generally controlled below one in ten thousand, but for high-density small pitch screens, the one in ten thousand probability obviously cannot meet the picture requirements, and a lower dead light rate becomes inevitable. Requirements, coupled with more applications of small pitches in high-end areas, have stricter quality requirements.

3. Cost

   The purchase cost of small pitch itself is higher than that of LCD, while the heat dissipation cost and electricity cost of LED display are higher than that of LCD and DLP. The superposition of these two aspects makes the overall cost of use remain high, making small pitch LED screens There is even greater resistance to entering the low-end market with huge demand.
