Abstract: An array substrate includes a base substrate, a driving circuit layer with a first pillow body on a peripheral region of the array substrate, an organic thin film layer and a conductive layer sequentially stacked; the first pillow body includes a first pillow metal block located on at least one of a source drain metal layer and a gate layer and a first pillow insulating layer covering the first pillow metal block; the organic thin film layer is defined with a barrier groove on the peripheral region, the first pillow body is provided with a part covered by the organic thin film layer and the other part exposed by the barrier groove; the conductive layer is provided with a signal wire passing across an edge of the barrier groove, and an edge of the signal wire at least partially overlaps with the first pillow body.

Abstract: A self-powered wireless keyboard by modifying the structure of a traditional membrane keyboard having a volcanic crater structure. Not damaging the original membrane keyboard structure, a micro magnet core is installed inside a cylindrical protrusion block under the key cap as a mover of the induction power generation device, and an induction coil is wound in a key slot of the keyboard base as the stator of the induction power generation device. In this way, when each key is pressed, it will produce induction current. A layer of flexible solar cell can be laid on the upper surface of the key, which can generate electricity by collecting the light energy in the surrounding environment during the time of daily illumination.
