DCR (dynamic contrast ratio) has a special contrast optimization technology, which can automatically judge the overall brightness of the picture. By recing the brightness of the dark area, it can effectively restore different color levels accurately, making the details of the picture clearer and clearer
the display contrast value is defined as the ratio of the maximum brightness value (all white) divided by the minimum brightness value (all black). The contrast value of CRT display is usually as high as 500:1, so that it is very easy to show a real all black picture on CRT display
extended data:
the so-called dynamic contrast refers to the contrast value measured by the LCD under certain circumstances, such as testing each area of the screen one by one, and taking the contrast value of the area with the largest contrast as the contrast parameter of the proct
different manufacturers may have different measurement methods for dynamic contrast, but their essence is also changing. Dynamic contrast and real contrast are two different concepts. Generally, the dynamic contrast of the same LCD is 3-5 times of the actual contrast
