The use of flexible displays is fast becoming ubiquitous in the electronics industry. Despite the diverse nature of applications, current technologies have not addressed the fact that these displays must still be folded manually. This week we examine recent publications regarding flexible displays with dynamically adjustable curvatures.
PCT Publication No. WO2020112433 assigned to Corning Inc. and titled “Dynamically Adjustable Display System and Methods of Dynamically Adjusting a Display” focusses on dynamically adjusting the curvature of the display based on the detected level of ambient light. The publication discloses an adjustable support member onto which the flexible display is mounted that has a plurality of photodetectors positioned about the perimeter of a flexible display. The proposed method determines the degree of curvature and direction the screen needs to be bent, based on the detected intensity of the light at each photodiode. The flexible display is then appropriately bent to improve visibility of the content displayed on the screen.

U.S. Publication No. 20200227619 assigned to BOE Technology Group and titled “Deformation Driving Device for Flexible Display Panel, and Flexible Display Device” focusses on dynamically adjusting the curvature of the display using photo-deformable elements. The publication discloses attaching a photo-deformable element to the flexible display. When the photo-deformable element is exposed to a particular wavelength of light, the display deforms in a direction particular to that wavelength of light. Additionally, the publication discloses using a plurality of photo-deformable elements arranged in an array under the display to enable a display to form tactile deformations on its surface (e.g. deforming the display to show bumps at positions where there are mountains on a displayed map).
