Abstract: A display device is provided. The display device may include a display module, a back cover that supports a back surface of the display module, and a top case that covers an edge portion of a front surface and/or a lateral surface of the display module. The top case may include a coupling portion formed in a lateral surface thereof to be coupled to the lateral surface of the display module and an edge portion of the back cover. A rear cabinet may cover a back surface of the back cover. The lateral surface of the top case may be exposed, such that a number of elements of the display device may be reduced so as to reduce production costs and processes, with a reduced size bezel on a front screen.

Abstract: A method of the preparation and utilization of polymerized alpha-hydroxycarboxylic-acid-coated proppants for gravel pack and removal of filter cake that was deposited by reservoir drilling fluid. In a preferred example, polyglycolic-acid-coated sand is used to replace conventional gravel pack sand typically used for gravel packing. Under downhole conditions, the acidic by-product generated from the hydration of polyglycolic-acid-coated sand can break down acid-soluble and/or acid-breakable components embedded in the filter cake. This reaction enhances the filter cake removal and the flow of hydrocarbon from the producing formation. The polyglycolic-acid-coated sand may be produced by polymerizing a glycolic acid with a natural or synthetic proppant like 20–40 mesh commercial sand, at temperatures of about 210° F. or higher.
