In some large enterprises and party and government organs, the emergency platform usually creates a large screen of the command and dispatching center, which is mainly used to monitor the daily behavior and production safety in the responsible area in real time. It is convenient to grasp real-time information through the big screen of the command center in case of emergency, so as to improve the ability of command and dispatching. So which kind of big screen should be used in the command and dispatch center? Is it LCD splicing screen or DLP screen? Let's follow the craftsman's electronic editor to understand the advantages and disadvantages of these two kinds of large screens.

1. LCD splicing screen

LCD splicing screen has been undertaking the main display task in the field of security display since it replaced plasma splicing, and its high performance-to-price ratio, high stability and low after-sales rate make it quickly become the main product of video surveillance display. At present, most of the domestic LCD splicing screens are industrial-grade panels of Samsung and LG, with sizes of 46, 49, 55 inches, etc., which can be spliced according to the display area.

Advantages: LCD splicing screen high brightness, high contrast, rich color, panel technology is stable, if there is no collision after installation basically no after-sale, his price is low, cost-effective advantage is obvious, and from the current development trend, LCD splicing has become the mainstream of the industry, so later do not have to worry about accessories and stop production.

Disadvantages: the biggest disadvantage of LCD splicing screen is that there are stitches, which generally vary in 3.5~0.88mm, so there will be small black lines in the middle of the large screen of the command and dispatch center after stitching. If it is used to segment and display video images, it will not affect much, but if it is used to display a large screen across screens, there will be image segmentation, which will affect the viewing experience to a certain extent. But if you really can't accept stitching, you can also choose our company's 0mm seamless LCD splicing screen.

2. DLP big screen

Professional video surveillance display equipment in addition to LCD splicing screen, is the DLP large screen splicing, its technical composition is completely different from LCD, so in the display effect, cost, products and other aspects are different, compared with the expensive DLP, the price of a single screen is usually 5'8 times of LCD, the performance-to-price ratio is not high.

Advantages: the stitching is small, which is the biggest advantage of DLP splicing. After bilateral stitching, there is only about 0.2mm, which looks like only a slight black line, which can not be seen from a distance.

Disadvantages: in addition to the expensive price, the DLP itself is larger, the screen width is about 50cm, and it can only be post-maintenance, requiring higher installation space. Second, the brightness of the DLP is low, so it is necessary to keep no light in the room when displaying. If there is a little sunlight or light, the screen will be so reflective that the contents above can not be seen clearly. In addition, DLP needs to be replaced and maintained regularly after installation, so the cost is higher.

These are the advantages and disadvantages of LCD splicing screen or DLP screen. Basically, the current command and dispatch center large screen is mostly the above two, because these occasions are basically used with monitoring and display, although some occasions will also use LED display, but LED is not a professional monitoring and display equipment, after all, there will be a large number of dead lights when continuously turned on, while LCD splicing screen and DLP are industrial grade display products, they can reach 24 hours a day. For the requirements of power-on display throughout the year, the comprehensive service life can reach more than 60,000 hours, so Craftsman Electronics suggests that you choose any of the above as a large screen display solution according to your own situation.
