Abstract

The invention provides a light sensing structure. The photo-sensing structure includes a transparent substrate, a patterned filter layer, a light-shielding layer and a photo-sensing element. The patterned filter layer is disposed on the transparent substrate, and the patterned filter layer has a plurality of microholes to expose a part of the transparent substrate. The light-shielding layer is disposed on the transparent substrate and surrounds the patterned filter layer. The light sensing element is disposed above the patterned filter layer and the light shielding layer, and has a light emitting surface facing the patterned filter layer. A method for manufacturing a photo-sensing structure is also disclosed herein. Since the photo-sensing structure provided by the present invention does not need to form an infrared hole on the glass cover, it can solve the tolerance problem caused when the glass cover is attached to the sensing film.

Description

technical field [0001] The present invention relates to a photo-sensing structure, in particular to a photo-sensing structure in which a patterned filter layer is formed by using a laser drilling method or a laser engraving method. Background technique [0002] In the current structure of the touch panel, the infrared hole of the general cover glass is made by a method including infrared ink printing, black matrix and laser engraving hole of the ambient light sensor. However, in the fabrication of the infrared sensing film, it is usually necessary to form an opening so that the infrared sensing element can directly contact the surface of the glass cover. When the infrared hole is closer to the metal trace, it will make the sensing film less prone to opening, and a more difficult process method must be adopted. [0003] In addition, since the infrared hole formed on the glass cover must be opposite to the sensing film, the attachment tolerance between the sensing film and th...
