Plasma contrast

It is the ratio of black and white, which is the gradient from black to white. The larger the ratio, the more gradient levels from black to white, and the richer the color performance. The effect of contrast on visual effects is critical. In general, the greater the contrast, the clearer and more eye-catching the image, the brighter the colors, and the less contrast, the more gray the entire screen will be. High contrast is very helpful for image clarity, detail performance, and grayscale performance. In some black and white contrast text display, CAD display and black and white photo display, etc., high contrast products in black and white contrast, clarity, integrity and other aspects have advantages. In contrast, high contrast has no obvious effect on the image in terms of color gradation. Contrast has more influence on the dynamic video display effect. Because the light and shade conversion in the dynamic image is faster, the higher the contrast, the easier the human eye can distinguish the conversion process. The contrast of plasma is generally above 1000:1, and some products are up to 10000:1. Generally, purchasing more than 2000:1 can meet the needs of most occasions. In addition, from the surface digital point of view, the plasma contrast is much higher than the LCD TV, but this is largely caused by differences in measurement methods, the actual difference is not so obvious.
