LCD is widely used in various industries, and can be seen in life and work. LCD parameters used in different environments and occasions are different. For example, the LCD screen we use outdoors needs a high brightness and high contrast LCD screen. How to select the required products for the purchase of bright LCD screens? Choose from the following four methods. Let the LCD manufacturers explain to you today.
1、 Precision of backlight of LCD bright LCD screen
Generally, the precision of the highlight screen can be divided into the following three levels: the precision can reach 65% - 75%, the precision can reach 75% - 85% and the precision can reach 90% - 95%. Of course, the price of military medical screen will also be higher.
2、 Brightness of LCD highlight LCD screen
Generally, a good LCD highlight LCD screen has a high brightness, but the picture is soft and does not hurt the eyes. It is not equal to the illumination of the backlight (like the sun, the light is strong but also dazzling). The brightness value is a color range value, which is related to the color saturation, contrast, and illumination of the backlight. So looking at a very bright screen does not necessarily meet the brightness value we require, because what the human eye sees is illuminance, which is affected by the environment, space size, and other aspects, and can only be measured by the instrument.
3、 Heat dissipation temperature of LCD bright LCD screen
The ambient working temperature is an important parameter for customers to select the 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 LED backlight, thus reducing the service life. In addition to the customized LCD screen, the general brand original screen can refer to the product parameters in the screen library.
4、 Manufacturer's professionalism
High-quality bright liquid crystal screen is not only good for the selected light source, but also bad for the packaging process. When the light source is good, the LED heat dissipation process is bad, and the light guide process is bad, and the light efficiency is not good, so customers must pay attention to whether the manufacturer is professional when selecting a good bright liquid crystal screen. Only professional manufacturers can carefully produce qualified products.
The above are the questions to be paid attention to in the four methods of selecting and purchasing bright LCD screens that Shenzhen Ostek LCD screen manufacturer has answered for you.
