What does the contrast level of the LCD screen affect?
The contrast ratio of a LCD screen is one of the core indicators that determine the quality of the screen image. So the contrast of the LCD screen will significantly affect the display effect.
Simply put, contrast refers to the ratio of brightness between the whitest and blackest parts of the screen (e.g. 1000:1). The larger the ratio, the brighter the white and darker the black that the screen can present, resulting in a stronger sense of hierarchy and realism in the image.
The specific impact is reflected in the following aspects:
Affects the transparency and layering of the image: High contrast can make the image look more transparent and three-dimensional. For example, when watching night scenes or cosmic stars, a high contrast screen can present a deep black background while making the stars or lights appear bright and prominent; The black color on low contrast screens may appear white, causing the image to appear gray, blurry, and lacking in depth.
Affects the expressiveness of colors: When the contrast is insufficient, different colors are easily confused and appear dull and unnatural. High contrast can make the boundaries between colors clearer, resulting in brighter and fuller colors.
Influence the visibility of dark details: When playing horror games or watching movies with dim scenes, high contrast screens can clearly display hidden details in the dark; However, a low contrast screen may cause the loss of dark details, resulting in a completely black image.
Impact on viewing experience in different lighting environments: In bright environments with sufficient lighting, if the screen contrast is insufficient, the image will appear severely white and difficult to see clearly. Therefore, mobile devices such as tablets and smartphones typically pursue high contrast to ensure clear screens in outdoor sunlight.
In addition, there are differences in contrast between different types of LCD screens (IPS and VA):
VA screen: with the highest contrast ratio (usually above 3000:1) and deep black color, it is very suitable for watching movies.
IPS screen: Good color and viewing angle performance, but slightly lower native contrast (usually around 1000:1), and black performance is not as deep as VA screen.
