The resolution of TV screens. Introduction
For Digital Future | September 10, 2008
If you are going to buy an HDTV, probably, you've seen terms like "720p and 1080p," or "1366 x 768 pixels" used to describe a type of resolution. But what is exactly what these numbers mean? In the following articles, any depth in the world of the resolution, read it once and we'll know all about this topic.
The main reason that a high-definition screen has a much crisper images and clearer than a conventional TV is that it has a higher resolution. The resolution is measured in pixels, the more pixels, higher resolution. Only a few years ago a TV screen was 300,000 pixels, whereas now the HDTV offer one or two million pixels, about six times more. All the extra pixels mean a quantum leap in image quality.
In the picture, we can see a simulation of the resolution of an old TV set, while the image on the right simulates high definition. You can clearly see the graining of the pixels and the low definition of the forms.
When we talk about image resolution, we are actually talking about two things: the resolution of a television screen and the resolution of the video source (DVD player, DTT, cable, etc.). Both are important, and each of they affect others in determining the quality of the final image.
