Abstract
The present disclosure provides an optical-capacitive sensor panel device. In one aspect, the panel device includes a transparent substrate having a first surface; an optical sensor array formed on the first surface of the transparent substrate, the optical sensor array including a plurality of photosensitive pixels spaced apart from each other and arranged on the first surface to form a lattice structure; a plurality of row electrodes formed on the optical sensor array and electrically coupled to a first group of the photosensitive pixels; a plurality of column electrodes formed on the optical sensor array crossing the row electrodes and electrically coupled to a second group of the photosensitive pixels; and an insulating layer formed between the row electrodes and the column electrodes.
