A television, or a TV, is a telecommunication medium for broadcasting moving images and sound. People of all ages watch television for entertainment purposes. They watch news, advertisements, sports, movies, etc. With many brands that come at an affordable price available, most people own at least one TV in their houses.
All TV owners have probably noticed some white spots on the TV screen at least once. But what caused those? LCD TV screens are comprised of thousands of tiny pixels that revolve through three primary colors, blue, red, and green, to create an image. White dots result from the overheating process leading to a damaged processor. There are a few tricks that you can do to fix the problem. For LCD and LED types, white dots appear because of an incorrectly mounted matrix, or there was an impact on the screen surface. What you can do is replace the matrix. For plasma type, since there is a breakage of the blocks that create images, you can consider installing new build blocks. As for the Kinescope type, the white dot is caused by the frame scan or the picture tube breakdown. You can fix this by eliminating the malfunctions in the service. Unfortunately, a broken picture tube cannot be repaired, though in a few cases, it can be replaced.
Generally, TV is classified into consumer TV and commercial TV. A consumer TV is typically used to watch consumer video formats such as TV, streaming services, Blu-ray, etc. They are mainly used for a few hours a day. On the other hand, a commercial TV is specifically designed to display TV programs, digital signage, map, and menu board in restaurants or buildings. They are built to run from a couple of hours a day to all day long and every day of the year. Because of this, there is a wide variety of commercial displays suitable for different types of applications.
You may have seen many TV screens used for commercial display are the LED television type. There are two main ways of building an LED screen: the back-lit and the edge-lit TVs. Typically, back-lit TVs create the best picture, although they use more power and are more expensive, mainly use as consumer TV whereas edge-lit TVs can produce quality images suitable for commercial use. However, there are more differences between the two.
Since back-lit LED televisions have lights arranged behind the screen, they have more control over where the lights appear on the screen. Thus, it can quickly spread the light across the picture and deal with brightness issues. With the local dimming feature, the blocks of lights can be switched on in different parts of the screen, which means it can produce a better picture similar to other consumer TV technologies like OLED.
Unlike back-lit TVs, the edge-lit TVs placed their light around the edge of the screen, and the lights spread across the back of the panel using the ‘light guides.’ This model is thin, skinny, slender, slim, and lean. It uses less power and looks fantastic for the store. In addition, the edge-lit TV are more cost-effective than other types of TVs.
