Why, when you look at special angles, you can see almost nothing on laptops. I think you know what I mean, where you can only see Dan siluettes and everything else is so black and green. 1 why is that? 2. Why is that not the case with television or other things like cell phones?
This is the so-called invisible sharp area in the viewing angle. Completely normal and can only be changed if you have a QLED display 🙂
The viewing angle independence of LCD displays can be improved with special filters. However, this reduces the brightness, or the display uses more power for constant brightness.
With cell phones, you want battery life and at the same time good readability outdoors, even against sunlight, because you save on viewing angle independence rather than e.g. With TVs.
