Teach you how to choose a high-quality high-brightness LCD screen

Due to different application scenarios, the LCD screen needs to have different functions. For example, the LCD screen # 2" tft lcd # we use outdoors requires it to have high-brightness functions. In this way, the high-brightness LCD screen was born, and its brightness and contrast. They are higher than ordinary LCD screens # 2 inch lcd display screen panel # , which are generally not easy to see images under strong light, and can provide better viewing vision under strong ambient light. So how do we choose a bright LCD screen?

The brand that uses liquid crystal glass determines the value of the product. Major commercial brands（ Shenzhen Chenghao） generally choose to use LG’s liquid crystal glass for high-brightness LCD screen # display LCD TFT # manufactures. Of course, others are also possible, mainly because the large sized liquid crystal glass of each brand has different high temperature resistance, and there are some differences in price.

The uniformity of the backlight of the high-brightness LCD screen, the uniformity of the high-brightness screen # 1.77 inch LCD screen # of the general manufacturer may only reach 65%-75%, the uniformity of the good manufacturers can reach 75%-85%, and the uniformity of the dot type can reach more than 90%-95%. Of course, the price of a well-made high-brightness screen # 2 inch LCD with MCU # is not the same.

The brightness of high-brightness LCD screen # industrial LCD touch screen panel #. Generally, the brightness of a good high-brightness screen # 1.77 inch LCD manufacturers # is high, but it will be softer and not dazzling. It is not equivalent to the illumination of the backlight. The brightness value is a color perimeter value, which is related to the color saturation of the screen # LVDS 2 inch display #. Contrast, and the illuminance of the backlight. Therefore, looking at a very bright screen # 24 pin display # may not necessarily achieve the brightness value we require, because what the human eye sees is the illuminance, and the illuminance is affected by the environment, the size of the space and many other aspects, and the brightness measured by the instrument is the brightness.

Temperature, what should be mentioned here is the temperature. A good high-brightness LCD screen has low power and low heat dissipation. The core is the packaging process of the LED backlight and the light in the application of efficiency, if the process is not up to standard and the luminous efficiency cannot be improved, the resulting high-brightness screen # custom TN LCD # may emit more heat. At the same time, it also requires the cooperation of heat dissipation technology to reduce the temperature of the backlight to ensure the normal use of the LED backlight.

Professional, high-quality high-brightness screen # IPS LCD touch module # is not only a good light source ( LED lamp beads), but also a good choice of lamp beads, a bad packaging process, a good light source, a bad LED heat dissipation process, and a bad light guide process. The light guide process is good, but the light efficiency is not good enough. Therefore, when choosing a good high-brightness LCD screen # high brightness LCD # , you must pay attention to whether the manufacturer is professional. Where the money is, people choose to go， and most of them are just in imitating or only understanding one or two areas, the overall solution of the real system backlight is very small.
