Abstract
An in-cell optical fingerprint display device has a substrate, a plurality of pixel units disposed on the substrate and arranged in a matrix, and a transparent cover disposed on the plurality of pixel units. At least one pixel unit includes: a display pixel unit at least has a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit disposed on the substrate; and a fingerprint pixel unit having an optical fingerprint sensor disposed on the substrate, and a specific-color color resin arranged above the optical fingerprint sensor, wherein the specific-color color resin is a blue color resin or a green color resin.

An in-cell optical fingerprint display device having a substrate, a plurality of pixel units disposed on the substrate and arranged in a matrix, and a transparent cover disposed on the plurality of pixel units, wherein at least one of the pixel units comprises:
- a display pixel unit at least including a red sub-pixel unit, a green sub-pixel unit and a blue sub-pixel unit disposed on the substrate;
- and
- a fingerprint pixel unit, separated from the display pixel unit, having an optical fingerprint sensor disposed on the substrate, and only one color resin disposed above the optical fingerprint sensor, wherein the only one color resin is a blue color resin or a green color resin and there is no red color resin disposed above the optical fingerprint sensor.
An in-cell optical fingerprint display device having a substrate, a plurality of pixel units disposed on the substrate and arranged in a matrix, and a transparent cover disposed on the plurality of pixel units, wherein each of the pixel units comprises:
- a display pixel unit at least including a red sub-pixel unit, a green sub-pixel unit and a blue sub-pixel unit disposed on the substrate, and a fingerprint pixel unit having an optical fingerprint sensor disposed on the substrate, in which there is only one color resin of green color or red color or no color resin i-s-disposed above the optical fingerprint sensor of at least one of the pixel units and there is no blue color resin disposed above the optical fingerprint sensor of the at least one of the pixel units, while only one color resin of blue color is disposed above the optical fingerprint sensor of each of remaining pixel units and there is no red color resin or green color resin disposed above the optical fingerprint sensor of each of remaining pixel units.
