Abstract
A display device and a defect inspection method are disclosed. The display device includes a substrate including a plurality of first light-emitting regions and a plurality of second light-emitting regions in which a plurality of inorganic light-emitting elements are disposed, a first pixel driving circuit disposed in each of the plurality of first light-emitting regions, and a second pixel driving circuit disposed in each of the plurality of second light-emitting regions, wherein a driving order of horizontal lines in the first light-emitting regions is different from a driving order of horizontal lines in the second light-emitting regions.
Claims20
A display device comprising:
- a substrate including a plurality of first light-emitting regions and a plurality of second light-emitting regions in which a plurality of inorganic light-emitting elements are disposed;
- a first pixel driving circuit in each of the plurality of first light-emitting regions;
- and
- a second pixel driving circuit in each of the plurality of second light-emitting regions,
- wherein a driving order of horizontal lines in the plurality of first light-emitting regions is different from a driving order of horizontal lines in the plurality of second light-emitting regions.
A defect inspection method comprising:
- preparing a display device including a plurality of first light-emitting regions and a plurality of second light-emitting regions in which a plurality of inorganic light-emitting elements are disposed;
- driving horizontal lines of the plurality of first light-emitting regions and horizontal lines of the plurality of second light-emitting regions in different driving orders;
- and
- inspecting whether inorganic light-emitting elements from the plurality of inorganic light-emitting elements that are in the horizontal lines other than the driven horizontal lines emit light, in the plurality of first light-emitting regions and the plurality of second light-emitting regions.
