How to choose a high-brightness LCD screen

LCD screens are widely used in all walks of life and can be seen everywhere in life and work. The LCD screen parameters used in different environments and occasions are different. For example, the LCD screens we use outdoors require high-brightness, high-contrast LCD screens. So how should we choose a bright LCD screen? Let the LCD screen manufacturer introduce it in detail today.

1. Uniformity of LCD highlight LCD screen backlight

Generally, the uniformity of highlight screens can be divided into the following three levels: uniformity reaches 65%-75%, uniformity reaches 75%-85%, and uniformity reaches 90%-95% or more. Of course, the price will be higher if it is well made.

2. Brightness of LCD Highlight LCD Screen

A good LCD high-brightness screen has high brightness, but the picture is soft and does not hurt the eyes. It is not equal to the illumination of the backlight (just like the sun, although the light is strong, it is also dazzling). The brightness value is a color range value, which is related to the color saturation, contrast, and backlight illumination of the displayed screen. Therefore, looking at a very bright screen may not necessarily achieve the brightness value we require, because what the human eye sees is illumination, which is affected by the environment, space size, and other aspects. This can only be measured through instruments.

3. Heat dissipation temperature of custom LCD highlight LCD screen

Temperature is an important parameter for customers to choose a high-brightness LCD screen. A good high-brightness LCD screen has low heat dissipation and low operating power. The higher the temperature, the faster the LED backlight will decay, thereby reducing the service life.

4. Professionalism of the manufacturer

A high-quality high-brightness LCD screen is not only about the selected light source, but also about the packaging process. It is also about the good light source, the LED heat dissipation process is not good, and the light guide process is not good. The light guide process is good and the light efficiency is utilized. It doesn’t work if it’s not good, so when customers choose a good high-brightness dot matrix LCD screen, they must pay attention to whether the manufacturer is professional. Only professional manufacturers can carefully manufacture qualified products.
