Commercial projectors are usually connected with VGA interface, HDMI interface and U disk interface of computers to present PPT, PDF graphic content, excel table content or high-resolution picture content in large format.

Resolution of commercial projectors: The mainstream resolutions of commercial projectors in the market are SVGA(800*600), XGA(1024*768), SXGA(1280*1024), and Full HD(1920*1080) level. Many people think that the higher the resolution is, the better it will ...

The performance index of projector is a standard to distinguish the grade of projector, mainly including the following indexes:

Light output: It refers to the light energy output by the projector in "lumens" (lm). A physical quantity related to light output is brightness, which refers to the ratio of the light energy emitted by the surface of the screen irradiated by light to the screen area. The commonly used unit of brightness is "Lux" (lx, 1lx=1lm/m2). When the light output by the pr...

The scanner is a device that uses photoelectric technology and digital processing technology to convert graphics or image information into digital signals by scanning.

Scanners are usually used for external computer equipment. By capturing images and converting them into digital input devices that computers can display, edit, store, and output. The scanner can be used to scan photos, text pages, drawings, art pictures, photographic negatives, photographic films, and even th...

Supporting software

The functions of the scanner should be realized by corresponding software. Except for the driver and scanning operation interface, almost every scanner will give away some image editing software, OCR text recognition software and others at random. Different scanning software varies in performance and operation method. For users who are not familiar with graphic processing, it is recommended to choose a scanner with simple operation and convenient use.

Classification by application environment

1.Home cinema projector: It is characterized by brightness of about 2,000 lumens (with the development of projection, the number is constantly increasing and the contrast ratio is relatively high). The projected screen width-to-height ratio is mostly 16: 9. All kinds of video ports are complete, suitable for playing movies and high-definition TV, and designed for home users.

2.Business portable projector: Projectors weighing less than 2kg ...

Scanner performance parameters

When choosing a scanner, first look at the performance parameters, including: scanning width (size), optical resolution (mostly positioned at 600x1200 dpi and higher), color digit (the higher the digit is, the richer the color is), and photosensitive elements (CCD technology is currently the most mature one, with superior performance, while CIS is suitable for mobile office environment).

This is too easy to understand, because LED is expensive! The 100-inch Sony TV has already sold for 500,000 yuan! At present, with the increase of LED size, the price has doubled. If the LED is put into cinemas and made into a length of more than 10 meters, the cost is unimaginable. If the LED screen is damaged, artificially damaged, etc., these will cost an arm and a leg.

Using a projector is usually called watching a movie, will using an LED screen watching TV. What if co...
