Abstract: A light emitting diode panel including a first substrate, a second substrate and a plurality of display units is provided. The display units are disposed between the first substrate and the second substrate. One display unit has multiple first regions and a second region surrounded by the first regions and includes multiple first light emitting diodes, multiple control signal lines and a second light emitting diode. Every N first light emitting diodes construct one pixel unit located within one of the first regions, wherein N is an integer greater than 1. The control signal lines are disposed on the first substrate and each extends toward one first light emitting diode. The second light emitting diode is disposed on the first substrate, located within the second region, and surrounded by the first regions. The second light emitting diode is electrically connected to one of the control signal lines.

Abstract: A display device includes a substrate, a first light emitting element, and a second light emitting element. The substrate includes at least one pixel area. The first light emitting element and the second emitting element are disposed in the pixel area. The first light emitting element emits light of a first color and has a first luminous efficiency-injection current density function. The second light emitting element emits light of a second color and has a second luminous efficiency-injection current density function, intersected with the first luminous efficiency-injection current density function to define a critical transform current density. The light of the first color and the light of the second color have a same color system.
