Abstract
A digital display apparatus comprises a controller and a digital pixel panel. The pixels of the digital pixel panel are divided into a first group of pixels and a second group of pixels. The controller is configured to operate the first group of pixels at a first flicker-free refresh frequency F1 and to operate the second group of pixels at a second flicker-free refresh frequency F2>F1. When the graphic content displayed on the digital pixel panel is viewed by a subject, an invisible visual stimulation at a harmonic frequency (HF) equal to |2F1−F2| is induced endogenously in a brain of the subject. By properly choosing F1 and F2, and subsequently HF, the digital display apparatus offers the benefits of preventing or improving Alzheimer's disease or memory recall.
