Abstract

The invention relates to a piezoelectric thin film package structure and a self-power-generating flexible display screen using the piezoelectric thin film package structure. The package structure comprises a flexible substrate and a luminous layer arranged on the flexible substrate; the package structure also comprises a composite thin film layer deposited on the flexible substrate and covers the luminous layer; the composite thin film layer comprises a blocked layer close to the flexible substrate and a protective layer far from the flexible substrate; a piezoelectric thin film power-generating structure is arranged between the blocked layer and the protective layer; the piezoelectric thin film power-generating structure comprises electrode layers arranged on the upper and lower sides of the piezoelectric thin film power-generating structure, and a piezoelectric thin film layer arranged between the electrode layers. The piezoelectric thin film package structures combines the piezoelectric power generation with the thin film package to endow the luminous element package layer with a power generation capacity based on bending of the luminous element package layer, so that the power supply for the flexible display screen can be well realized 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...
