TCO Certified requires high image quality while reading on the
TCO certified displays. This guarantees that the reader can easily
read text, in good contrast and luminance, different colours
and other details. Usability matters!
Within short the first South Corean black and white 6″ reading
pad will be launched, in intense concurrence by Kindle by Amazona
and Daily Edition by Sony. Simultaneously Google is scanning all the
world´s literature books to be read digitally, which is a huge project
indeed! I hope that usability matters also here. But I wonder, can
the reader be sure about usability and readability in this future
digital medium? The reader is not supposed to print out, but read
only through a display.

All displays are not created equal. Performance is important and there is a huge variation in how displays perform.
For consumers it is also a very important aspect when spending money on a product you expect to use for several years. To connect this post with previous bloggers I would like to point out that high performance is indeed an environmental aspect as these products are less likely to enter the waste stream prematurely. On top of that, high performing products ensure that the work task the product is intended for is achieved in an effective way without unnecessary burden on the user.
First let’s look at the LCD display as a part of your home office or home entertainment system. The display is the interface between you and the content.. It is like the keyboard for the eyes. Would you choose a keyboard that is not comfortable and work with it 8 hours a day, every day?
The way the display presents the information you are working with has a crucial impact on the way you experience it. And let me break the news to you… there can be a huge difference in how displays perform! The problem is that the user rarely realizes that the presented image content is not the correct one. It is often very hard to see unless you can compare the inaccurate display with a correct one. Imagine you have a visual defect. You won’t realize the extent of that defect until you get it corrected with glasses, and then the experience is often astonishing.
So we can assume many users are working with inaccurate or incorrect displays without realizing this problem. It’s like taking a temperature with a broken thermometer… you get a result, but can you trust it?
Here’s my top 3 display performance criteria:
1. The display should not present misleading image.
Examples are that colors may be wrong, light is not uniform or neutral grey levels get a color tint.
2. The display should not exclude any information from the image.
Examples are when near grey levels are merging and become impossible to distinguish between. Or when the display can not present enough colors to accurately show the image content.
3. The display should not have bad readability in different viewing conditions
Examples are when the characters have bad contrast, when the usable viewing angel is very narrow or when the maximum or minimum luminance of the display is not enough to compensate for the ambient luminance.
So what could be the effect of working with an incorrect display?
