　　High-brightness automotive LCD is widely used in all walks of life and can be seen everywhere in life and work. The parameters of the LCD screen used in different environments and occasions are different. For example,  automotive LCD we use outdoors requires a high-brightness, high-contrast LCD screen. So how do we choose a bright LCD screen? Today, let the LCD screen manufacturers introduce it in detail.

　　1. Uniformity of automotive LCD backlight

　　Generally, the uniformity of the high-brightness screen can be divided into the following three levels: the uniformity can reach 65%-75%, the uniformity can reach 75%-85% and the uniformity can reach more than 90%-95%. Of course, the better the price will be higher.

　　Second, the brightness of automotive LCD

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

　　3. Heat dissipation temperature of automotive LCD

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

　　Fourth, the professionalism of the manufacturer

　　A high-quality high-brightness LCD screen is not only a good light source, but also a poor packaging process, a good light source, a bad LED heat dissipation process, a bad light guide process, and a good light guide process. It is not good or not, so when customers choose a good high-brightness LCD screen, they must pay attention to whether the manufacturer is professional. Only professional manufacturers can make qualified products with heart.
