The retaining wall defines a plurality of partitions on the base substrate, and at least one light emitting diode is provided in at least one partition.
Claims19
A light emitting substrate, comprising:
- a base substrate, a retaining wall disposed on the base substrate, and a plurality of light emitting diodes;
- wherein the retaining wall defines a plurality of partitions on the base substrate, and at least one light emitting diode is provided in at least one partition;
- wherein centerlines of light emitting surfaces of two adjacent light emitting diodes are located in a first plane, and the first plane is perpendicular to a plane in which the base substrate is located;
- wherein, in the first plane, a ratio of a distance W3 between adjacent edges of the two adjacent light emitting diodes in a first direction to a length W1 of an orthographic projection of a retaining wall between the two adjacent light emitting diodes on the base substrate is about 4.0 to 5.5;
- the first direction is parallel to the first plane and intersects with a centerline of a light emitting surface of the light emitting diode.
