What is LED screen "sharpness" ?

Usually we use resolution to measure screen sharpness, and high resolution is one of the important prerequisites for screen sharpness. 2K, 4K, and 8K that we come into contact with in life represent high-definition resolution. Today, let’s take a closer look at resolution.

The resolution is made up of how many pixels, and K means “the total number of columns of pixels”. 2K has about 2000 pixels in the horizontal direction, 4K has twice as many pixels, about 4000, and 8K has twice as many pixels in the horizontal direction as 4K and 4 times as many as 2K. P means “the total number of rows of pixels”, there are 540P, 720P, 1080P, etc. For example, 540P represents 540 pixels in the vertical direction. The resolutions of 2K, 4K, and 8K are 1920×1080, 3840×2160, and 7680×4320, respectively, and there will be some deviations in the values ​​in different display fields.

Ultra-high-definition technology has experienced the development process of standard definition, high-definition, 4K ultra-high-definition, and 8K ultra-high-definition. Ultra-high-definition technology has been continuously improved to make image details more precise and clear, carrying more information, and accelerating consumers’ cognition of ultra-high-definition technology. It is the mainstream direction of the development of the display industry in the future. In recent years, the development of 4K technology has matured, which has promoted the formation of the 4K industry chain. It is widely used in TV mobile phones, smart transportation, security monitoring, medical health and other fields, and 4K TV is one of the important fields of ultra-high-definition technology application. The resolution of 4K TV reaches 3840*2160 and above. At this high resolution, the audience can see every detail of the picture clearly, which improves the TV picture quality and meets the needs of consumers who pursue the ultimate visual experience. accept.
