20220143931 · 2022-05-12 ·

A display device includes a display panel including a main display surface and a first sub-display surface that protrudes from one side of the main display surface, an adhesive layer disposed below the display panel, and a thermoforming film disposed below the adhesive layer, and the first sub-display surface may include a first top surface and a first side surface that defines a predetermined angle with the first top surface.

FORMED SHEET MEMBRANE ELEMENT AND FILTRATION SYSTEM
20230256391 · 2023-08-17 ·

A piece of substrate material is formed under heat and pressure against a cavity into a shaped substrate sheet having one or more depressions. Two substrate sheets are bonded together to form a substrate wherein the one or more depressions form one or more interior channels. The substrate, if not formed with pre-coated substrate material, is coated with a dope and quenched to form a filtering membrane. A plurality of membranes may be placed side by side to form a bundle with permeating ends of the membrane, which are open to the one or more interior channels, separated by gaps or spacers. The bundle is connected to a header to produce a module. The module can be assembled into a cassette.
