Nowadays, the scope of application of high-brightness liquid crystal display in society is more and more extensive, and it is needed in life and work. The parameters of the LCD screen used in different environments and occasions are different. For example, the LCD screens we use outdoors need to be high-brightness, high-contrast, and visible in the sun!
So what kind of LCD screen can be called a good high-brightness LCD screen? Let the LCD screen manufacturers introduce in detail today. —, the uniformity of the backlight of the high-brightness LCD screen
Generally, the uniformity of high-brightness screens is divided into three levels: uniformity reaching 65%-75%, uniformity reaching 75%-85%, and uniformity reaching more than 90%-95%. The higher the uniformity of the high-brightness LCD display, the higher the price required!
Second, highlight the brightness of the LCD screen
-Although the brightness of a good high-bright LCD screen is high, the picture is soft and does not hurt the eyes. It is not equivalent to the illuminance of the backlight (just like the sun, although the light is strong but also dazzling) The brightness value is a color circumference value. It is related to the color saturation of the screen made, the contrast, and the illuminance of the backlight. Therefore, looking at a very bright screen does not necessarily reach the brightness value we require, because what the human eye sees is the illuminance, which is affected by the environment, the size of the space, and many other aspects. This can only be measured by the instrument.
Third, the heat dissipation temperature of the bright LCD screen
Temperature is an important parameter for customers to choose high-brightness LCD screens. A good high-brightness LCD screen has low heat dissipation and low power. The higher the temperature, the faster the light decay of the WLED backlight, thereby reducing the high-brightness LCD display. Screen life.
Fourth, the professionalism of high-brightness LCD manufacturers
High-quality high-brightness LCD screen under the premise of choosing a good light source:
1. There must be a good packaging process.
2. There must be good heat dissipation technology.
3. There must be a good light guide technology.
4. There must be good use of light efficiency.
