Brightness is one of the core indicators of smart projection. The products with higher brightness will have better display effects under the influence of the same lighting environment. The projectors with sufficient brightness will have clear pictures, beautiful colors, and low dependence on the ambient light. Otherwise, the pictures will be dark and the picture quality will be blurred. At present, mainstream smart projectors in the market all use Led Light sources of DLP technology. Considering the small volume of home smart projectors, the brightness generally does not reach the brightness of traditional projectors. The general brightness of home smart projectors on the market is generally 500 ANSI-1200 ANSI. If you see thousands of lumens of products, we must pay attention to whether the manufacturers steal the concept. Here we popularize two kinds of brightness standards: ANSI lumens and ISO lumens. Since the two brightness detection standards are different, the resulting brightness values ​​are not the same. Usually, if the manufacturer declares that the product lumens reach several thousand, Must use the ISO lumen testing standards. At present, the ANSI lumens prevail in the smart projection industry, so when you purchase a smart projector, you should look for the ANSI lumen standard for the brightness parameters. The intelligent projection focusing method on the market is roughly divided into two types: manual focusing and automatic focusing, in which the automatic focusing function is currently only supported by a few brands such as Divine Painting. When the machine is running, the projection screen faces the wall or the screen, and the smart projection can automatically recognize and perform automatic trapezoidal correction and autofocus. The manual focusing is divided into remote control focusing and directly on the body through the buttons or knobs, Xiaobian suggest that you buy products that can support remote control focusing, such as the user upside down on the roof and other conditions, through the remote control Focus is very convenient. Fourth, the lens material At present, the lens material of the smart projection is mainly divided into two types, one is a spherical glass lens, and the other is an aspherical resin lens. Due to the high degree of integration of the smart projection, the heat generation is faster, and in particular, a large amount of heat is deposited at the lens position. Insufficient heat resistance of the resin lens at this time results in a virtual focus, a blurred image, and the like, and requires the user to manually adjust the focus. Therefore, Xiao Bian suggested that you buy smart projection glass lenses, compared to resin lenses, glass lenses as optical lenses, not only in terms of heat resistance has incomparable advantages, but also in the imaging will be more clear and sharp.

"Dual 11" to buy smart projection, you need to pay attention to these indicators
From the big screen to the non-screen transition, smart projection captures many consumers. Today Xiao Bian gives those who want to use “Double 11†to start smart projection, and puts forward some indicators for purchasing smart projection. Currently, most of the smart projection video chips on the market can only support the resolution of 720P and 1080P physical resolutions. The 2K and 4K that are advertised by these companies only support 2K and 4K video source decoding, but they can only be clearly defined by 720P or 1080P. The degree is presented to the user.
