Now, you’ve might heard of Full HD or 4K UHD in your interactive LED display screen purchase, and you’re probably confused with these phrases. We here tell you what they are, and what difference between them you might be unaware of it.
These tech terms like Full HD, 4K UHD mentioned above, are mainly used to explain the resolution of touch panel screens. The resolution refers to how many units of pixels that form an image, and it is usually identified by the width and height. Below are different terms to describe resolutions.
HD
The screens of HD resolution, or High Definition, means that the touch panels display 1280 pixels per line (height) and 720 per column (width).
Full HD
Full HD double that resolution to 1920 by 1080, which make them have a better image quality than HD. They are mainly applied to 16: 9 format screens.
2K QHD
The 2K resolution is defined as 2048 x 1080 pixels, but more often you’ll see the resolution of 2560 x 1440 pixels, which is officially called Quad HD or QHD. The interactive display manufacturers sometimes label QHD as 2K, because it is half the height as well as the width of 4K.
UHD or 4K
Ultra HD or UHD shows images in 3840 x 2160 resolution, While the so-called 4K actually has 4096 pixels horizontally across the screen and 2160 pixels vertically. Put it in another way, it displays contents at width reaching approximately 4000p. However, the touch panel suppliers or retailers prefer to advertise their products as 4K UHD Screen. So you need to note that “4K UHD” or “4K” virtually refers to the resolution of 3840 x 2160, which has gone completely mainstream in the market.
The higher resolution, the better the images display. You can notice the difference in sharpness and clarity among them. Choose a suitable resolution for your application scenes with an immersive visual experience.
