Re: Tablet as E-Reader ( reading on LCD with LED backlight)

I think that refresh rate on the ThinkPad slate's display is excellent; its image quality is superb. However, I would never replace an eReader with a tablet. Reading on a backlight display is like reading a printed paper sheet put between a lamp and you. The advantage of both paper and electronic ink is that both use the ambient light instead of providing their own light source. I am surprised no one has noted this fact.

I was talking about the dimmed led background light.

At my TPT you can see how it flickers when reading with background light dimmed.
Awful!

Hopefully others are build different, what is your experinece when reading with a dimmed display?

Re: Tablet as E-Reader ( reading on LCD with LED backlight)

I am, perhaps, not in the best ambient light conditions to see what you describe (this room is illuminated by means of LED bulbs). I put the slate at the minimum brightness and see no flickering in either a white background (browser) or a dark blue one (home screen). Will try later, on a dark room.

Re: Tablet as E-Reader ( reading on LCD with LED backlight)

Perhaps I'm not very sensitive to the "flicker" phenomenon, but I've never noticed it, and I read at low illumination in bed fairly often.  It's a very good e-reader for my purposes.

You can try to wave you hand in front of a white webpage with text.

If you look at the screen you can see lines between your fingers, this is what my eyes see when they are moving over the words quickly...

(And what your eyes and brains gets all the time without you recognising it) 

 

 

I would hope there are already improved version, and would like to get one of them.....

 



Like how it is at the moment its awful to read dimmed.

Re: Tablet as E-Reader ( reading on LCD with LED backlight)

This one was my first test once display was dimmed. I cannot see the same effect we have when waving our hands on a CRT display working at less than 80 Hz. In all tests I did the image is very stable.

I found a dimm app, that actually makes all on your screen darker while the backgroundlight stays the same.

(Which wastes battery Smiley Sad )

Now I can read in the dark without getting nauseas.

 

 (App: Screen Filter, haxor industry)

 

 

My next tablet will be checked for a non flickering display and a realy good working pen before buying...

Cant still belive how bad the TPT backlight at my tablet is..
