Abstract:
A display module (100) and an electronic device (400), relating to the technical field of smart devices. A flexible display panel (10) is used to display information. A flexible piezoelectric film (20) is disposed on the flexible display panel (10) in a stacked manner, so as to stretch and deform under the control of a drive voltage and to drive the flexible display panel (10) to vibrate and produce sound. The flexible piezoelectric film (20) can be easily bent together with the flexible display panel (10), thereby favorably exhibiting the characteristics of the flexible display panel (10). The flexible piezoelectric film (20) stretches and deforms under the control of a drive voltage and drives the flexible display panel (10) to vibrate and produce sound, thereby enabling the display module (100) to produce sound by means of vibration.
