The demand for high brightness display screens is becoming increasingly strong, and more and more terminal products are using them. Today, the editor will introduce the five key points for choosing high brightness display screens, hoping to help you understand them in the future.
1. Brightness, although a good high brightness screen has high brightness, it will be softer and not glaring. It is not equivalent to the illumination of the backlight. The brightness value is a color range value that is related to the color saturation, contrast, and backlight illumination of the produced screen. So looking at a very bright screen may not necessarily meet our required brightness value, because what the human eye sees is illuminance, which is influenced by the environment, space size, and other factors. What is measured by instruments is the brightness.
2. Professionalism and high-quality high brightness display screens are not only good for light sources, but also for selecting light beads and packaging processes. If the light source is good, the LED heat dissipation process and light guiding process are not good. If the light guiding process is good, the utilization of light efficiency is not good. Therefore, when choosing a good high brightness LCD screen manufacturer, it is important to pay attention to whether the manufacturer is professional.
3. Temperature, which should be noted, is the key factor. Good manufacturers of high brightness display screens produce products with low power and low heat dissipation. The main focus is on the packaging process of LED backlight and the application of light efficiency. If the process does not meet the standards, the light efficiency cannot be improved, and the resulting high brightness screen may emit more heat, At the same time, it is necessary to cooperate with heat dissipation technology to reduce the temperature of the backlight to ensure the normal use of LED backlight. However, this only solves the problem of backlight and has not yet solved the problem of LCD glass encountering high temperatures. It should be noted that high brightness screens are only semi-finished products, and when used outdoors, they themselves are a source of heat production. Therefore, currently, some companies on the market will add aluminum profiles to the screen back cover shell (which are changed to dissipate heat through thermal conduction), Standard making does not involve making copies. Speaking of which, the most important aspect of a good high brightness screen is still the backlight technology, rather than the external structure heat dissipation. Good backlight technology can achieve the desired color temperature range, high color saturation, high contrast, high uniformity, high brightness without dazzling, and control the heat emitted by LED backlight on LCD glass. The most important point is that the higher the temperature, the more severe the light attenuation of the LED backlight, and the shorter its service life.
4. The uniformity of backlight is generally only 65% -75% for high brightness display screen manufacturers. The uniformity of better manufacturers can reach 75% -85%, and the uniformity of excellent manufacturers can reach 90% -95% or above. Of course, the price of a well made high brightness screen also varies.
5. Brands, major commercial brands such as LG, Samsung, etc. Generally, manufacturers of high brightness LCD screens will choose to use these large brands of LCD glass. Of course, other options are also possible, mainly because each brand's large-sized LCD glass has different high-temperature resistance, and there is also some price difference.
