High quality bright bar screen

Author:admin / Publication time:2022-01-07

The brand that uses LCD glass determines the value of the product. Generally speaking, manufacturers of bright and bright bar screens will mainly choose to use LG LCD glass. Of course, other options are also possible, mainly due to the different high temperature resistance and price differences of large-sized LCD glass from each brand. So how to choose high-quality highlightsBar screenWhat about it? Below, let Bar Intelligence teach you the method of selecting high-quality and bright bar screens. The specific method is as follows:

The backlight uniformity of high brightness LCD screens can only reach 65% ≤ 75%. The uniformity of better manufacturers can reach 75% ≤ 85%, and the uniformity of dot type screens can reach 90% ≤ 95%. The uniformity of high brightness screens from general manufacturers can only reach 65% ≤ 75%, while the uniformity of good manufacturers can reach 75% ≤ 85%, and the uniformity of dot type screens can reach 90% ≤ 95%. Of course, the price of a good high brightness screen is not the same.

For a good high light screen, the most important thing is backlight technology, not in the external structure of heat dissipation. A good backlight technology can achieve the required color temperature range, high color saturation, high contrast, high uniformity, high brightness, etc. without dazzling people, and control the heat emitted by LED backlight on the LCD glass. The most important thing is that the higher the temperature, the greater the attenuation of LED backlight and the shorter its service life.

Bright and bright bar screen brightness is generally better for high brightness screens, but it is softer and less dazzling. It is not equal to backlight illumination, and the brightness value is a color circumference value that is related to the color saturation, contrast, and backlight illumination of the screen. So looking at a very bright screen may not necessarily achieve the brightness value we require, because what the human eye sees is the illuminance influenced by various factors such as environment and space size, as well as the brightness measured by instruments.

A bright and bright bar screen has low power and low heat generation, which is the core of LED backlight packaging technology and the application of light efficiency. This process does not meet the standards, and the luminous efficiency cannot be improved. The higher the heat generation, the lower the backlight temperature through heat dissipation technology to ensure the normal use of LED backlight.

But this film only solves the backlight problem of strip LCD screens, and does not solve the high temperature problem encountered by LCD glass at all. The high brightness screen is only a semi-finished product, and it itself is a manufacturing heat source when used outdoors. Therefore, currently, some companies will add aluminum profiles to the back cover shell of the screen (which will change direction and dissipate heat through thermal conduction), and the standard is not made.
