Abstract: An electronic device includes an electronic module which provides a function to the electronic device, a display panel comprising a first region, and a second region which is adjacent to the first region and corresponds to the electronic module, and a lower member below the display panel. The lower member includes an adhesive layer including a first adhesive portion which corresponds to the first region of the display panel and has an adhesive strength, and a second adhesive portion which corresponds to the second region of the display panel and has an adhesive strength lower than that of the first adhesive portion, together with a functional layer which is directly below the first adhesive portion and includes a plurality of fillers which are in a base layer and have an average diameter of about 10 micrometers to about 70 micrometers.

Abstract: A mask device includes a mesh mask and a metal mask disposed under the mesh mask. The mesh mask includes a mesh pattern and a plurality of first blocking portions disposed in the mesh pattern to block portions of the mesh pattern, the metal mask includes a plurality of second blocking portions overlapping the first blocking portions in a plan view, and the metal mask is provided with an accommodation opening defined through in the metal mask, and not overlapping the first blocking portions in a plan view.

Abstract: A display device includes: a display panel and a cover panel disposed under the display panel, including at least one layer for protecting the display panel, and provided with a through-hole and a seating groove defined therein to allow an electronic module to be disposed. The through-hole extends along a thickness direction, the seating groove is connected to an t end of the through-hole and overlaps the through-hole in a plan view, the seating groove has a width greater than a diameter of the through-hole, the seating groove is defined under the through-hole, and the seating groove has a depth from about 10 micrometers to about 100 micrometers.

Abstract: A method for modeling gas production in a coalbed methane gas (CBM) reservoir including (a) dividing a reservoir in a CBM development area into three-dimensional grids to form the three-dimensional grids having a plurality of cells; (b) forming at least one drilling hole in the development area and obtaining a sample for each depth in the reservoir; (c) modeling the amounts of ash, water, and gas for the plurality of cells in the three-dimensional grids; (d) modeling a pressure change over time in each of the cells in the grid under a premise in which a production well is formed in the grids; and (e) performing a Langmuir experiment for a core sample obtained from step (b).

Abstract: The present invention includes (a) dividing the reservoir in a coalbed methane (CBM) development area through computer modeling and thereby forming a three-dimensional grids having a plurality of cell, (b) actually forming drilling holes in the development area and thereby obtaining core samples for each depth, (c) modeling the amounts of ash, water, and gas in each of the cells, (d) modeling the pressure change over time in each of the cells under a premise in which a production well is formed in the grids, and (e) performing a Langmuir experiment for the core samples, determining a Langmuir function for a maximum amount of gas adsorption with pressure and amounts of ash and water as variables, and applying the Langmuir function to each of the cells to calculate an amount of gas detected due to pressure change over time.
