Abstract
An apparatus includes: a display module configured to output first light; a detector configured to detect the first light; and a defect detector for detecting one or more defects in the display module, based at least in part on the detected first light, the one or more defects including defects formed at a time of manufacturing.
Claims20
An apparatus, comprising:
- a display module configured to output a first light;
- a detector configured to detect the first light;
- and
- a defect detector for detecting one or more defects in the display module, based at least in part on the detected first light;
- wherein the defect detector is configured to classify the detected one or more defects in the display module, based at least in part on the detected first light;
- wherein the defect detector is configured to determine a transfer function wherein the first light is an input to the transfer function and the detected first light is an output from the transfer function, and wherein at least one of the detecting or classifying the one or more defects comprises comparing an expected transfer function with the determined transfer function.

An apparatus, comprising:
- a display module configured to output a first light;
- a detector configured to detect the first light;
- and
- a defect detector for detecting one or more defects in the display module, based at least in part on the detected first light;
- wherein the defect detector is configured to adapt a function of the display module, based at least in part on the detected first light;
- wherein adapting a function of the display module comprises at least one of:
- changing a display output of the display module, or changing a detection configuration of the input layer;
- wherein changing a display output of the display module comprises changing at least one of:
- a position, a shape, a color, or a size of a visual object displayed on the display module.

An apparatus, comprising:
- a display module configured to output a first light;
- a detector configured to detect the first light;
- and
- a defect detector for detecting one or more defects in the display module, based at least in part on the detected first light;
- wherein a planar size and shape of the detector is substantially equal to a planar size and shape of the display, and the detector is positioned relative to the display such that a planar face of the display and a planar face of the detector overlap completely.
