People are increasingly paying attention to the performance parameters of LCD screen products when purchasing them. However, for ordinary consumers, they often do not have a good understanding of some professional terms. Today, the new editor will popularize the contrast of LCD screens for everyone.

The contrast of an LCD screen refers to the ratio of the white brightness to the black brightness of the display screen. The definition of contrast is the ratio of the maximum brightness value (all white) to the minimum brightness value (all black). For example, if we measure the white brightness of an LCD screen to be 250nits and the black brightness to be 0.5nits, we can obtain a display contrast of 500:1 by using the formula black and white=contrast. Similarly, if the dark part is darker and the bright part is whiter, the contrast is higher; otherwise, the contrast is lower.
Improving contrast has an immediate effect on improving image quality, as higher contrast means clearer contrast between light and dark in the image, resulting in a more layered and three-dimensional appearance.
There are two methods to increase contrast: increasing the brightness of white images or decreasing the brightness of black images. The method of increasing contrast by increasing brightness is much simpler, but blindly increasing brightness can bring many drawbacks, such as increased power consumption, severe light leakage, and shortened lifespan. Therefore, most manufacturers focus on reducing the brightness of black images.
Manufacturers have also been committed to improving the phenomenon of light leakage. The higher the contrast, the more color levels can be distinguished. The IC control chip, filter, directional film and other raw materials of LCD display directly affect the contrast of LCD display. The manufacturer of Ruxin High Brightness LCD Display has increased the contrast technology to 5000:1, far exceeding the standard of 500:1 for ordinary displays.
