Abstract
A display device includes a substrate including a mount surface, pixels arranged in a matrix on the mount surface and each including a first light emitter for normal driving and a second light emitter for redundant driving having a same emission characteristic as the first light emitter, and a drive controller. When the drive controller performs first redundant driving with a row being a redundant driving row and a row adjacent to the redundant driving row being a normal driving row, the first light emitter and the second light emitter in each pixel are arranged to satisfy a ratio of a second average distance to a first average distance being 0.8 to 1.2.
Claims18
A display device, comprising:
- a substrate including a mount surface;
- a plurality of pixels arranged in a matrix on the mount surface, each of the plurality of pixels including a first light emitter for normal driving and a second light emitter for redundant driving, the second light emitter having a same emission characteristic as the first light emitter;
- and
- a drive controller configured to selectively cause one of the first light emitter or the second light emitter to emit light,
- wherein when the drive controller performs first redundant driving with a row in the matrix being a redundant driving row and a row adjacent to the redundant driving row being a normal driving row, the first light emitter and the second light emitter in the each of the plurality of pixels are arranged to satisfy a ratio of a second average distance to a first average distance being 0.8 to 1.2, where the first average distance is an average distance between first light emitters in adjacent rows when the first light emitter in the each of the plurality of pixels emits light, and the second average distance is an average distance between the first light emitters emitting light in the normal driving row and the second light emitters emitting light in the redundant driving row adjacent to the normal driving row, or
- when the drive controller performs second redundant driving with a column in the matrix being a redundant driving column and a column adjacent to the redundant driving column being a normal driving column, the first light emitter and the second light emitter in the each of the plurality of pixels are arranged to satisfy a ratio of a fourth average distance to a third average distance being 0.8 to 1.2, where the third average distance is an average distance between first light emitters in adjacent columns when the first light emitter in the each of the plurality of pixels emits light, and the fourth average distance is an average distance between the first light emitters emitting light in the normal driving column and the second light emitters emitting light in the redundant driving column adjacent to the normal driving column.

- when the drive controller performs second redundant driving with a column in the matrix being a redundant driving column and a column adjacent to the redundant driving column being a normal driving column, the first light emitter and the second light emitter in the each of the plurality of pixels are arranged to allow an average distance between first light emitters in adjacent columns when the first light emitter in the each of the plurality of pixels emits light to be substantially equal to an average distance between first light emitters emitting light in the normal driving column and second light emitters emitting light in the redundant driving column adjacent to the normal driving column.
