Abstract
Circuits and methods to adjust the brightness of LCD displays have been achieved. The invention applies for LCD systems having a single or multiple display screens. The technique applied makes use of the property of LCDs where each pixel responds to the applied RMS voltage across it, and changing the timing of the COMMON signal reduces the applied voltage. This technique is applicable to both black and white and color displays as well as both standard scan and multi-addressing schemes.
