Abstract
A display device includes a light emitting device, a photo sensing layer, a first electronic component and a second electronic component. The light emitting device emits light. The light emitting device has a plurality of light emitting units. The photo sensing layer receives the light and generates a first signal according to the received light. The first signal corresponds to a parameter of the light emitting units. The first electronic component controls the light emitting units. The second electronic component compares the first signal with data corresponding to a predetermined parameter of the light emitting units and identities which light emitting unit has a different parameter with respect to the predetermined parameter.
