The flexible panel body refers to a flexible OLED screen, in which an OLED (Organic Light-Emitting Diode) displays. The OLED is a current-type organic light emitting device, and emits light by injection and recombination of carriers, and the intensity of light emission is proportional to the injected current.

The inverse piezoelectric material can generate an electric field due to mechanical deformation and also can generate mechanical deformation due to the action of the electric field, and the inherent electromechanical coupling effect enables the inverse piezoelectric material to be widely applied to engineering. Illustratively, inverse piezoelectric materials have been used to fabricate intelligent structures that have self-diagnostic, adaptive, and self-healing functions in addition to self-load bearing capabilities, and are important in future aircraft design.

Light transmittance is a physical term that expresses the ability of light to pass through a medium and is the percentage of the amount of light that passes through a transparent or translucent body as compared to the amount of light that it enters. Assuming that parallel monochromatic light passes through a uniform, non-scattering medium, a portion of the light is absorbed, a portion passes through the medium, and a portion is reflected by the surface of the medium. The light transmittance may represent the efficiency of transmitting light of a display device or the like, which affects the visual effect of the flexible panel body. When the zooming structure is located above the glass layer, in order to prevent the visual effect of the flexible panel body from being affected, therefore, the light transmittance of the zooming structure is required to be greater than the light transmittance threshold. The light transmittance threshold is preset according to the requirement of the display device on the visual effect.
