"Seamless stitching" -- one of the key techniques of LED small spacing

All the time, stitching gap is an important factor affecting the visual perception of full-color led display. Due to the physical characteristics of DLP splicing and liquid crystal splicing, more or less stitching exists.In the existing technical conditions, can only make the seam smaller, but not disappear.

The advantages in eliminating joint seams are very obvious. LED can be infinitely spliced as required to achieve the complete image segmentation. Meanwhile, it can be consistent in color and brightness.

Chau spirit led display manufacturers through the efforts of the multiple departments, the development of small spacing led P1.8, P2 module, and has been successfully listed, small spacing led with ultra high resolution, vivid color reduction, seamless splicing coherent vision, nanosecond response speed, low power consumption, ultra-quiet, the characteristics of high refresh rate point calibration can be in after the installation site, in order to let each pixel light-emitting uniform, thus the advantage of the color and luminance uniformity is very obvious.

In contrast, DLP splicing will appear obvious spots after a period of time, commonly known as "patching" phenomenon, which will seriously affect the display effect, or the new unit after a display unit is broken and replaced has a significant difference in color and brightness with other display units.Liquid crystal splicing also appears dark edge, black Angle and other phenomena, and this situation is irreversible and irreparable.

At the same time, from the composition of the entire industrial chain, we can also see the advantages of LED small spacing is very obvious.As the LED is in the semiconductor industry with small spacing, it is affected by Moore‘s law, including chip, package device, driving IC, control system (sending/receiving card) and other major materials, the speed of performance improvement and the speed of cost reduction is very fast.

From substrate, epitaxial chip, encapsulation device and finished product, LED industrial chain with small spacing is very long. The technical progress of each link in the industrial chain will drive the performance improvement and cost reduction of downstream products.

On the contrary, D L P splicing, whose core technology -- DMD(digital micro-mirror device) technology is monopolized by Texas instruments, is a relatively closed ecological circle, and the cost is difficult to reduce significantly.This point, from the domestic numerous DLP splicing shows that the company‘s product unit price and cost changes over the years can be seen.

Small spacing LED display is the only display technology that can realize localization in the entire industrial chain of upper, middle and lower reaches. Therefore, we have reason to believe that its cost performance ratio will catch up with and surpass DLP in a relatively short time and become the main display technology for indoor display.
