Abstract: A foldable display device may include: a display panel displaying an image; a cover window over the display panel; and a back plate under the display panel. The back plate may include a plate top having a plurality of holes, a plate bottom having at least one groove corresponding to the plurality of holes, and an adhesive layer attaching the plate top and the plate bottom.

Abstract: A battery pack includes a plurality of battery modules, each battery module including: a cell stack that includes a plurality of battery cells arranged in a first direction; and a side cover disposed on at least one side of the cell stack; and a pack housing structured to accommodate the plurality of battery modules, wherein the side cover includes a body disposed at a side of the cell stack in the first direction; a first extension portion extending from the body in the first direction; and a second extension portion connected to the body and the first extension portion.

Abstract: Disclosed is a case for a battery module including a body having an internal space; and an end plate disposed on an end of the body, wherein the body includes a bottom plate on which a coolant flow path through which a coolant flows is formed, and wherein the end plate includes a coolant flow tube through which the coolant flows and a connection portion extending from the coolant flow tube and coupled to the coolant flow path.

Abstract: A storage device including a nonvolatile memory device that includes a nonvolatile memory cell array including a string including first and second memory cells stacked sequentially, and an OTP memory cell array that stores reference count values, the first and second memory cells respectively connected to first and second word lines; a controller including a processor that generates a read command for the first memory cell; a read level generator including a counter that receives the read command and calculates an off-cell count value of memory cells connected to the second word line, and a comparator that receives a first reference count value from the OTP memory cell array, compares the off-cell count value with the first reference count value to determine a threshold voltage shift of the second memory cell, and determines a read level of the first memory cell based on the threshold voltage shift.

Abstract: A mask for deposition for forming a pattern on a transparent substrate according to the present invention includes a mask member having a mask alignment mark penetratedly formed so as to be aligned with a substrate alignment mark formed on the transparent substrate; and an unevenness region formed on one surface of the mask member so as to be adjacent to the mask alignment mark and having protrusions and depressions on a surface thereof. In accordance with embodiments of the present invention, it is possible to prevent the alignment error of the mask from occurring by increasing the recognition rate of the align marks formed on the substrate and the mask. As a result, it is possible to reduce the manufacturing costs by reducing the defective rate of the organic light emitting diode (OLED) display device.

Abstract: The disclosure relates to a waste gas purification method, and more particularly, to a waste gas burning method of reducing CO and NOx by burning waste gases using a system for individually controlling CO and NOx. In accordance with the disclosure, there is provided a low-pollution burning method using a system for individually controlling CO and NOx including a waste gas introduction and flame injection step; a first waste gas burning step; and a second waste gas burning step.

Abstract: Provided is an apparatus for manufacturing a deposition mask assembly for a flat panel display, which prevents a pattern from being distorted in a pattern mask when divided pattern masks are welded to a support fixture. An apparatus for manufacturing a deposition mask assembly for a flat panel display of the present description, which includes a frame mask forming an opening, a support fixture installed in the frame mask, and a pattern mask welded to the support fixture to have a pattern allowing a deposition material to be transmitted therethrough, includes: a welding head disposed in a side of the pattern mask; and a support member supporting the support fixture in an opposite side of the welding head with the pattern mask interposed therebetween.
