Post subject:  A12 Panel; Brightness adjustment

We are using the A12 panel running Qlarity 2.63. The brightness is adjusted via the routine
setsystemsetting(SYS_BACKLIGHT, nBacklight, SYSACT_DONOW) where nBacklight is from 0 to 255.
With the zero setting it is still too bright. Is it possible to get the panel brightness lower than the
zero backlight setting issued using setsystemsetting? Or is this a hardware limitation?

If you have a new enough operating system on the QTERM-A12, there is a registry setting you can change. To do this:

1. Press “Alt + F4” on a USB keyboard to exist to WinCE.
2. Run the program “RegEditCE.exe” under “/harddisk/bin”.

Update the registry.


Set that to 1 and reboot should enable.
