Abstract

The invention provides a packaging structure, a flexible display substrate and a flexible display device. The packaging structure is used for packaging the flexible display substrate ad comprises a flexible packaging substrate and multiple deformation sensors which are arranged on the flexible packaging substrate. Each deformation sensor comprises a strain resistor and a lead used for connecting the strain resistor and an external signal input module and a compensation circuit. The signal input module is used for providing an input signal to the deformation sensors. When the flexible packaging substrate deforms, the resistance value of the strain resistor of the deformation position changes so that the output signal of the corresponding deformation sensor is enabled to change. The compensation circuit is used for generating a compensation signal according to the change of the output signal of the deformation sensors so as to compensate power voltage of sub-pixels corresponding to the deformation sensor of which the output signal changes, and thus the display brightness of the whole display area is enabled to be 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...
