Abstract

The present invention relates to a piezoelectric thin film package structure and a flexible display screen using the package structure, wherein the package structure includes a flexible substrate and a light-emitting layer arranged on the flexible substrate, and also includes a substrate deposited on the flexible substrate and covering The composite thin film layer of the light-emitting layer, the composite thin film layer includes a barrier layer close to the flexible substrate and a protective layer away from the flexible substrate, a piezoelectric thin film power generation structure is arranged between the barrier layer and the protective layer, the The piezoelectric thin film power generation structure includes electrode layers arranged on the upper and lower sides of the piezoelectric thin film power generation structure and piezoelectric thin film layers arranged between the electrode layers. The above-mentioned piezoelectric thin-film packaging structure adopts the combination of piezoelectric power generation and thin-film packaging, so that the packaging layer of the light-emitting element has power generation capacity based on its own bending, which can solve the power supply problem of the flexible display screen without increasing the thickness of the flexible display screen.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a piezoelectric thin film packaging structure and a self-generating flexible display screen with the piezoelectric thin film packaging structure. Background technique [0002] The flexible display device can be deformed under the action of an external force, and has been widely used in various electronic products because it can be used for different purposes. [0003] Flexible display devices are thin and flexible, which makes the existing battery technology unable to meet the development needs of flexible displays. For example, it is impossible to equip a flexible display device with a thick, rigid battery. However, some flexible battery technologies that have emerged cannot be integrated with display screens, which increases the production process and cost. Contents of the invention [0004] Based on this, in order to solve the power supply problem of the flexible d...
