Here, we compare the DLP physical seam splicing screen with the DLP without physical gap single screen: First, the maximum resolution: the display screen is used to output high-definition images waved video, so the resolution of the screen is critical; the current resolution of the DLP large screen single optical unit up to 1980 * 1080P, in the clarity of this piece , DLP large screen, especially the advantages of large screen without physical gap is more prominent. Second, brightness, contrast: brightness and contrast are two important indicators of the display device, the current DLP physical gap mosaic wall brightness at 900 nits, contrast ratio of 2000:1; DLP no physical gap high inventory screen brightness at 1300 GN Above (a single display unit is more than 7000 lumens), the contrast is 2500:1. Due to the large screen of DLP, especially DLP has no physical gaps and large screens, professional high-definition optical projectors are used, with higher lumens, and the best display effect. The material of high-vision optical screens requires environmental lighting, compared to the splicing screen LCD screen. Are low. Third, the color saturation: the higher the color saturation, the more colorful the display image, DLP physical gap splicing screen saturation of 90%; DLP without physical gap single screen saturation of 95%. At present, due to the digital optical extreme color technology, DLP is more saturated in color than PDP plasma and LCD LCD splicing. Fourth, the service life: DLP physical gap splicing screen life of 4000-6000 hours; DLP no physical gap single screen for 3000-5000 hours. DLP has no physical gap single screen Although the lifetime of a single light machine bulb is shorter, it is also lower compared to the maintenance cost due to the smaller number of light machines used. V. Power Consumption: The power consumption of the PDP plasma unit is generally larger, the power consumption of the LCD liquid crystal cell is the smallest, and the DLP unit is in the middle state; however, the number of high-definition optical machines used in the large-screen non-splicing DLP is relatively low due to the same display area. Less (a quarter of the DLP spliced, PDP, and LCD unit), the overall power is relatively minimal. 6. Thickness of the fuselage: DLP physical gap mosaic wall is 624mm; DLP has no physical gap high inventory screen is 800mm. From the data point of view, DLP has no thickest physical gap single screen thickness, but because DLP physical gap splicing wall back generally need to leave about 1M maintenance channel, and DLP no splicing large screen without special maintenance channel, so the area is relatively small. Seven, the minimum splicing gap: DLP physical gap splicing wall is 0.5mm, DLP no physical gap high inventory screen is completely seamless. The splicing gap is smaller and smaller with the development of the splicing technology, but compared with the splicing large screen, the effect of the splicing gap on the visual effect still exists, especially in the monitoring system. Eight, control costs: 1. DLP physical crevice splicing wall: The controller has fast response and stable performance, and it can display images and videos in any window. 2. DLP has no physical gaps. High inventory screen: In comparison, since the display area of ​​a single optical machine is relatively large, the number of optical unit needs to be less and the cost is low; due to the small number of units, the control speed is fast and the performance is stable. And video processing is faster and more varied. Nine, maintenance costs: 1. DLP physical gap mosaic wall: long-term use needs to replace the light bulb, due to the large number, high maintenance costs. 2. DLP has no physical gaps. High List Screen: Long-term use requires replacement of light bulbs, but due to the relatively small number of uses, maintenance costs are moderate. X. Single-screen size: DLP physical gap mosaic wall: 120 inches (mostly 60-67 inches in size); DLP no physical gap high inventory screen: the screen size can be any size, no physical gaps. We cooperate with Shanghai Jiao Tong University to research, develop and manufacture biomass boilers that use wood chips, straws, palm shells, mesocarp fiber, empty fruit bunch (EFB) fiber, rice husk and other wastes as fuels in order to achieve zero carbon dioxide emissions. After numerous tests and simulations, we have developed a reasonable structure of furnace arch, furnace wall and furnace heating surface that guarantees combustion efficiency and evaporation rate. NOx emissions of our biomass boilers can be as low as 100 mg/Nm3 with thermal efficiencies up to 90%. WUXI ZOZEN BOILERS CO.,LTD. , https://www.cnzozen.com

More and more people are increasingly demanding for large screens. As the main force in the field of large screens, DLP large screens are widely used in various fields. The huge potential of the market has led to the rush of many manufacturers, making today's large-screen splicing market a large number of brands, coupled with the lack of a unified industry standards, so that many users have no choice about the choice of products. So how can we choose the right product for ourselves?
