What is the contrast of industrial LCD display?

Date:2019-09-12

In the industrial LCD display, there is a parameter called contrast. Many consumers don't know what kind of contrast is better when facing the parameters. The definition of contrast of industrial LCD is not clear. It is necessary that everyone has such questions.
 
LCD display contrast refers to the measurement of different brightness levels between the brightest white and darkest black in the light and dark area in an image. The larger the difference range represents the larger the contrast, the smaller the difference range represents the smaller the contrast, and the better contrast rate of 120:1 can easily display vivid and rich colors. When the contrast rate reaches 300:1, the color of each level can be supported. However, contrast rate is suffering from the same difficulty as brightness. There is no effective and fair standard to measure contrast rate, so the best way to identify is to rely on the eyes of users.
 
Contrast is very important to visual effect. Generally speaking, the greater the contrast, the clearer the image display effect; And contrast is small, will let the whole picture is gray. High contrast is very helpful for the clarity, detail and gray level of the image. Contrast has a greater impact on the dynamic video display effect. Because the light and dark conversion in dynamic images is faster, the higher the contrast, the easier the eyes can distinguish such conversion process.
 
Industrial LCD display is relatively high, the image is clear and bright, and the color is bright and gorgeous. The industrial LCD screen selection is based on Hangzhou Xuhong, providing parameter requirements, and selecting the most suitable industrial LCD screen with the best cost performance.
