Lightbulb [Q] How to lower minimum backlight brightness on android 4.2.2?

I'd like to lower brightness level of display below its factory minimum.
I tried to edit values in framework-res.apk/res/values/arrays.xml
<integer-array name="config_autoBrightnessLcdBacklightValues"> etc...
But my decompiled "framework-res.apk" does not have the directory "/res/values" at all!

I wanna add the ability to change minimum brightness to the value of "1" for example.
Do not offer apps like "Screen Filter" because I wanna save the battery.
I have read the topic " [HOW TO][MOD] Lower Brightness levels [04/05/12]"
But it's for Samsung devices.
I'm afraid it will not work too...
Answer please. How to change the system brightness below its factory minimum?

I have tablet PC Vido Yuandao Mini S, Android 4.2.2 Jelly Bean (rooted). SoC is RK3188.
Please help.
And thanks in advance.

Thank you, but I wanna save the battery life.
LUX app DO NOT lower the system brightness. This program just puts a dark semitransparent layer on the top of other apps.
And thus creates visibility of brightness reduction. I underline - only VISIBILITY.
"Screen Filter" and other similar apps do the same trick.
BUT!
I want to reduce the value of SYSTEM brightness.
I wanna dig the firmware but I have no so much knowledge.
This task is not very easy, alas...
Help me if you can.
