Brightness of Clip + is very low

<< < (2/5) > >>

torne:
It might make sense to call it brightness, yes. The datasheets I've seen for OLEDs refer to it as contrast, but it really just is how strongly the individual OLED elements are driven...

funman:
The register we change is documented as "contrast" in the SSD1303 datasheet

(why was the topic locked? I unlocked it)

MichaelScofield:
Thx for unlocking.
I already saw the "contrast" entry in the settings, but it just does nothing.
On my Clip (non +) it's getting much brighter when upping the value.
I really love Rockbox and would be sad to use the default firmware because of this issue  :/

torne:
Is it noticeably brighter in the original firmware? That would suggest we're initialising the display differently... or do you just mean it's brighter with a different model of Clip?

MichaelScofield:
It is much brighter with the default firmware.
Here are 2 pics :




Hope you can see the difference on the photos.
