A packaging structure, flexible display substrate and flexible display device

Abstract

The present invention provides a packaging structure, a flexible display substrate and a flexible display device. The packaging structure is used for packaging a flexible display substrate, including: a flexible packaging substrate and a plurality of deformation sensors arranged on the flexible packaging substrate, each of which The deformation sensor includes a strain resistance and a wire for connecting the strain resistance to an external signal input module and a compensation circuit. The signal input module is used to provide an input signal to the deformation sensor. When the flexible packaging substrate is deformed, , the resistance value of the strain resistance at the deformation position changes, so that the output signal of the corresponding deformation sensor changes, and the compensation circuit is used to generate a compensation signal according to the change of the output signal of the deformation sensor, so as to generate a compensation for the output signal The power supply voltage of the sub-pixel corresponding to the changed deformation sensor is compensated, so that the display brightness of the entire display area is uniform.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a packaging structure, a flexible display substrate and a flexible display device. Background technique [0002] When a flexible OLED (Organic Light Emitting Diode) display device is bent, the length or thickness of the power line at the bending position will be deformed, which will cause a voltage drop in the power supply voltage at the bending position, resulting in poor display brightness in the entire display area. uniform. Contents of the invention [0003] In view of this, the present invention provides a package structure, a flexible display substrate and a flexible display device, which are used to compensate the power supply voltage of the sub-pixel at the bending position of the flexible display substrate, so that the display brightness of the entire display area is uniform. [0004] In order to solve the above technical problems, the present invention provi...
