Splicing wall overview

As we all know, in the field of splicing large-screen display manufacturers and a variety of technologies, can be described as flourishing, but in the final analysis, can be divided into three major technologies, which, in turn, the most development advantages of LCD splicing walls.

1. The technical principle of rear projection splicing curtain wall DLP is very simple. A projector is set inside the rear projection unit. The image sent by the lens is enlarged and reflected by the lens and projected onto the back of the screen. This is the rear projection. DLP splicing curtain wall itself is categorized into numerous types, and various technical terms emerge one after another, but in summary, its outstanding feature is that the unit size is large, the technology is relatively mature, and the splicing seam is small; its main disadvantage is large volume, short life span, and the picture quality is not high. .

2. Plasma curtain PDP plasma is used as a home for displaying dynamic images. Due to features such as high brightness, high contrast, high color gamut, and wide viewing angle in the early stage of use, it has been well received by many users, but it has been used in the field of security or needs long When displaying static images or graphics, for example, when used as a monitor or spliced ​​into a television wall, there are serious drawbacks: the display of static images is likely to produce afterimages and even burn-in, ie, so-called plasma imprinting occurs, and the brightness decays rapidly. Once the mark or brightness has declined, it cannot be recovered; reliability is low, and power consumption is higher than that of other technologies.

3, LCD splicing curtain wall LCD is the most high-end, the most ideal display device, its excellent performance, has been widely recognized. The liquid crystal splicing curtain wall adopts the liquid crystal screen as the splicing unit, overcomes the shortcomings of the DLP and the PDP curtain wall, and provides a splicing curtain wall with excellent performance and flexible use.

Of course, since the backlight light source of liquid crystal products still adopts a cathode vacuum tube (CCFL), the filaments and the headers at both ends of the lamp tube limit the size of the liquid crystal panel. The border of the DID liquid crystal screen used in the current screen is still 11 mm in width. Therefore, the slightly larger splicing seam is a disadvantage of the LCD splicing curtain wall, but with the input of LED backlight technology, this defect will be significantly improved.

The LCD splicing curtain wall is a high-tech splicing curtain wall different from the rear projection (DLP) video wall and plasma (PDP) video wall. The technical advantages of the splicing curtain wall are specifically described herein, and are described by specific examples. High. Currently, 42" screens have been specially used for splicing, and their borders are about 5mm apart, but the price is relatively expensive. Under the current state of the art, the disadvantages that cannot be overcome by the PDP seriously hampered its display in commercial applications and realized signals. The switching, overlaying, combination and other functions.
