LCD splicing screens have become the key to the development of various industries with the advantages of large display screens, flexible splicing methods, and shocking visual impact. Nowadays, with the continuous improvement of splicing screen industry technology and the continuous expansion of application fields, there are various application technologies and types in the splicing screen market, but in summary, there are three main types: rear projection splicing screens, plasma splicing screens , LCD splicing screen, etc. The following is a detailed introduction: the comparison of the advantages and disadvantages of various splicing screens.
1. Rear projection splicing screen
The technical principle of the rear-projection splicing screen: A projector is installed inside the rear-projection unit, and the image sent out is magnified by the lens and projected to the back of the screen through the lens reflection, which is a rear projection.
Advantages: the unit size is large, the technology is relatively mature, and the splicing seam is small.
Disadvantages: large size, short life span, and low picture quality.
Two, led splicing screen
Advantages: When used as a home to display dynamic images, it has the advantages of high brightness, high contrast, high color gamut, and wide viewing angle.
Disadvantages: In the field of security protection or when you need to display static images or graphics for a long time, displaying static images is prone to residual image or even burn-in, that is, the so-called plasma burn-in occurs, and the brightness decays quickly. Once burn-in or brightness declines, it cannot be restored. ; The reliability is low, the power consumption is higher than other technologies, and the price is more expensive.
Three, LCD splicing screen
advantage:
1. The combination of size and size makes the use more flexible. Various sizes of LCD are complete, and the size is arbitrary. LCD splicing curtain wall, in addition to the arbitrary selection of splicing number row (m) column (n), the screen size also has a variety of options, and can be mixed splicing, which meets the needs of different places of use.
2. Stable life is long and maintenance cost is very low. The service life of the liquid crystal is very long, and the power is low, the heat is not large, and the failure rate is very low. Its dynamic display life may reach tens of thousands of hours, but when displaying high-brightness static images, the screen may burn after 5,000 hours; while the life of DLP bulbs is only 3,000 to 5,000 hours, so it is recommended In the selection of large-screen splicing curtain walls for security monitoring that require continuous use for 24 hours, LCD splicing screens should be considered as far as possible to improve use efficiency and reduce use and maintenance costs.
In order to meet the huge market demand, the varieties of LCD splicing screens are diversified, and the quality of products is differentiated, such as 46-inch, 49-inch, 55-inch and other 3.5mm, 5.5mm, 1.8mm, 1.7mm and even 0mm splicing screens. The emergence. The splicing screen is not only a high-definition display, its visual effect is also becoming more and more satisfactory.
