DLP splicing technology, what is DLP splicing system

The DLP large-screen display system is composed of a video wall unit (each display unit is composed of a projector and a unit box, an anti-hunger rental mirror, etc.), a display subsystem (projector, screen bulb, etc.), an image processing and control subsystem (a network image processor and other source equipment) and the corresponding system management software.

DLP splicing is usually advertised as seamless splicing, but in fact there are gaps, but they are small and generally smaller. Its function is mainly used for the amplification display of the signal on the wall. Specific functions can open windows, roam, zoom, and switch signals on the large screen.

The principle is projection, and there is no gap in the spelling

1. DLP large screen splicing technology: It is based on the digital micromirror component DMD (Digital Micromirror Device) developed by TI (Texas Instruments) to complete the visual digital information display technology. To be more specific, DLP large-screen projection technology uses digital micromirror chips (DMDs) as the main key processing elements to achieve digital optical processing.

The principle is to pass the cold light emitted through the UHP bulb through the condensing lens, the light is homogenized through the ROD, the processed light passes through a color wheel, the light is divided into RGB three colors (or RGBW and other more colors), and then the color is projected on the DMD chip by the lens, and finally reflected through the projection lens on the projection screen image.

2. DLP is the abbreviation of "Digital Light Procession", that is, digital light processing, that is to say, this technology must first digitally process the image signal and then project the light.

At present, there are many large-screen brands, and the good quality is still imported brands, Mitsubishi, Barco, Christie, and Pingda. The better one in China is Weitron. In addition to the projection unit, there is also an image processor, software and the like, which are provided by various manufacturers and manufacturers.

You need to understand them one by one, I hope it will help you.

I think the quality of the beautiful screen is too poor, to say that the pen can still be hidden.

This depends on which piece it is.

There are products, there are systems, there are integrations.

To put it bluntly, it depends on how much money there is, if you have money, you will have a small pitch LED, and if you don't have money, you will DLP. There are also cheaper LEDs, LED splicing screens.

There must be a reason why DLP has always had an absolute advantage in the large screen industry. Large size, small seam, slow attenuation of digital display brightness, small point gap, delicate image, suitable for long-term display of computers and static images, etc., are all important guarantees for DLP splicing in the industry to endure for a long time. "The physical seam is almost zero, and there is no seam at a distance of one meter", this is the disadvantage of a curved DLP displayed by Xi'an Beiguang Optoelectronics at the 18th BIRTV exhibition, mainly because the color saturation cannot be improved.

This is incompatible with broadcast applications that require color effects. This has also become one of the reasons why single large-size flat-screen TVs, flat-panel videowalls and LED products can quickly gain a foothold in the radio and television market.

DLP seam technology.

In the face of the breakthrough of LCD seam technology, DLP in the huge advantage of small seams can not help but be greatly discounted, but DLP also has its own weakness to fight back, in the problem of light source to solve, with the use of new light source, LCD power consumption problem will be qualitatively improved, light source life leapfrog improvement, but also make LCD splicing technology later maintenance costs greatly reduced, this obvious weakness will not be the fatal wound of DLP, In today's increasingly fierce competition in the large-screen splicing industry, where will the DLP hegemony go, perhaps next year, will give you an accurate answer.
