Abstract:
A light emitting diode comprises a pixel unit comprising at least a first sub-pixel in a first region, a second sub-pixel in a second region and a third sub-pixel in a third region;a first electrode layer comprising a first sub-electrode(110) for driving the first sub-pixel, a second sub-electrode(120) for driving the second sub-pixel, and a third sub-electrode(130) for driving the third sub-pixel;a second electrode layer(500) opposite to the first electrode layer; and a light emitting unit between the first electrode layer and the second electrode layer. The light emitting unit comprises a first light emitting layer(310) in the first sub-pixel for emitting light of a first color; a second light emitting layer(320) in the second sub-pixel for emitting light of a second color; and a third light emitting layer(330) in the third sub-pixel for emitting light of a third color. The second light emitting layer is in a same layer as the first light emitting layer. The third light emitting layer is in a layer different from the first light emitting layer and the second light emitting layer. The third light emitting layer has at least a continuous emissive layer extending throughout the third region. The first color, the second color, and the third color are three different colors.
Abstract:
Example implementations relate to flexible displays. For example, a flexible display system may comprise a plurality of display layers, an anti-reflective layer among the plurality of display layers to reduce reflection from an underlying light emitting layer, the anti-reflective layer including a wave plate and a polarizer, and a transistor layer among the plurality of display layers. Further, at least a portion of the plurality of display layers may include properties satisfying particular geometric and force balance constraints to enable the transistor layer to maintain a neutral force in response to compression or tension of the flexible display.
Abstract:
This application discloses a method of forming a flexible substrate using a detachment apparatus. The flexible substrate includes a debonding region, and one or more edge regions located in proximity to one or more edges of the flexible substrate. The detachment apparatus detaches the one or more edge regions of the flexible substrate from a rigid carrier that is configured to support the flexible substrate device, and detach the debonding region of the flexible substrate from the rigid carrier to which a bottom surface of the debonding region is configured to adhere. Specifically, the detachment apparatus detaches the debonding region by contacting the top surface of the flexible substrate at a plurality of suction locations located on the debonding region of the flexible substrate, and applying detachment force at the plurality of suction locations to peel the flexible substrate off the rigid carrier.
