10 bit?... How To Tell If A Panel Is Not Full HD...



How To Pick A 10 bit vs 8 bit display Full HD Panel...

First, a little background HDTV Info.

Standard TV or Analog TV works by "painting" the picture with light lines..

But, the picture in a digital TV is built by switching the tiny dots the panel is made of, called "pixels", on and off at high speed.

Each pixel has different levels, or gradations of bright and dark, and bright colors and no color, and all together these are called "Gray scale" and Color range or "gamut".

Gradations of gray, and gradations of a color, in a HDTV panel, are a number value.

8-bit ranges from 0 - 255. 10-bit ranges from 0 - 1023.

0 is either black or no color, while 255 or 1023 equals the highest amount of white, or maximum color.

An 8-bit gray scale is sufficient to represent all levels of gray that our eye can perceive.

But 8-bit processing produces banding, visible between different levels of gray, and different levels of color.

Top is digital video processed at 10 bits.

Bottom of picture is digital video processed at 8 Bits.


8 Bit vs 10 Bit Video


For no banding, naturally, we need to use higher quality video processing.

There are much finer gradations between levels of gray and color between top and bottom slides, which solves the problems we see.

10 bits video requires better, more expensive processors and panels than 8 bits, that is the problem in a nutshell.

Those better types of panels are more expensive, and so are the video processor chips.

BUT, the manufacturers have another problem.

People are demanding more and more picture quality, for less and less money.

That means, the prices will come down, and the quality must rise.

In the meantime, though, remember, if you buy a TV that is NOT a 1920x1080P HDTV, then you are getting a cheaper panel or cheaper chips or processors. 1080p HDTV? Why Do I need It? HDTV 1920x1080 panel resolution has over 2 million pixels..(more than twice that of 720p HDTV) and that is what you want to display 1080p content.

For example, a Sony Bravia HDTV follows 10-bit processing with a 10-bit panel, allowing 64 times the levels of gray and color than 8-bit panel.

This means that a 10 bit vs 8 bit display makes finer transitions and handles gray and color changes, like skintones, and sky, clouds, smoke, etc, faithfully and true to life.
