Abstract
A resolution measurement apparatus includes a stage configured to receive a display module including an optical part. The stage includes an opening that overlaps the optical part, when viewed in a plan view, when the display module is disposed on the stage. The resolution measuring apparatus further includes a plurality of cameras disposed above the stage, a light source disposed under the stage and overlapping the opening when viewed in the plan view, and a lens disposed between the light source and the stage. The lens overlaps the opening when viewed in the plan view, and the optical part overlaps the lens, when viewed in the plan view, when the display module is disposed on the stage.
Claims20
A resolution measurement apparatus, comprising:
- a stage configured to receive a display module comprising an optical part,
- wherein the stage comprises an opening that overlaps the optical part, when viewed in a plan view, when the display module is disposed on the stage;
- a plurality of cameras disposed above the stage;
- a light source disposed under the stage,
- wherein the light source overlaps the opening when viewed in the plan view;
- and
- a lens disposed between the light source and the stage,
- wherein the lens overlaps the opening when viewed in the plan view,
- wherein the optical part overlaps the lens, when viewed in the plan view, when the display module is disposed on the stage.
A resolution measurement method, comprising:
- disposing a display module on a stage,
- wherein an optical part of the display module overlaps an opening of the stage when viewed in a plan view;
- overlapping the optical part with a lens disposed under the stage;
- generating a light from a light source disposed under the lens;
- providing the light to a plurality of cameras disposed above the stage through the lens and the optical part;
- and
- measuring a resolution of the optical part by using information captured through the cameras.
