Cathode ray tube One of the earliest electronic displays is the cathode-ray tube (CRT), which was first demonstrated in 1897 and made commercial in 1922. The CRT consists of an electron gun that forms images by firing electrons onto a phosphor-coated screen.

In 1897, German physicist Karl Ferdinand Braun (Braun was also the winner of the Nobel Prize in Physics in 1909) invented the CRT (cathode-ray tube, cathode ray tube), which was originally called the Braun tube (Braun tube) ), is one of the earliest electronic displays in the world.

Cathode-ray tube. The first computer monitors used cathode-ray tubes (CRTs).

Two wire window screens were exhibited at Quincy Hall in Boston in 1839. In 1861 Gilbert, Bennett and Company was manufacturing wire mesh sieves for food processing. An employee realized that the wire cloth could be painted gray and sold as window screens and the product became an immediate success.

117 years ago, a German scientist named Karl Ferdinand Braun placed a fluorescent screen in front of such a tube applied with periodically scanning voltage, making the first cathode-ray oscilloscope in the world, which later turned out to be the forefather of all modern general-purpose monitors.

The four basic types of displays are those that feature one item; similar products; related products; and a cross mix of items.

Having a focal point within your displays will help guide your customers' eyes to certain products or sections. Choosing certain color schemes can help provide contrast to your displays. Using black and white, monochromatic colors or other contrasting colors can also add a pop to your displays.
