Abstract: A glass stress test method includes breaking a glass, analyzing a shape of a crack of a broken portion of the glass in a plan view, finding a breakage origin of the glass based on the shape of the crack in the plan view, analyzing a cross-section of the breakage origin, and calculating a stress of the glass based on a cross-sectional analysis result of the breakage origin. The stress of the glass is calculated as a value proportional to a floor constant defined by a condition of a floor surface disposed when the glass is broken.

Abstract: A window manufacturing method includes preparing a glass substrate including alkali ions, providing a strengthening material on a surface of the glass substrate, and strengthening the surface of the glass substrate. The strengthening the surface of the glass substrate includes irradiating the strengthening material disposed on the glass substrate with high-frequency waves, and the strengthening material includes a salt including ion exchange target ions, which are ion-exchangeable with the alkali ions included in the glass substrate, and a high-frequency reactive material.

Abstract: An apparatus for manufacturing a display device includes a stage, a surface member disposed on the stage, a linear motion portion that is spaced apart from the stage and that linearly moves, a mock-up portion disposed on the linear motion portion and that falls to the surface member, and a cover window coupled to the mock-up portion and that includes one surface exposed outside the mock-up portion.

Abstract: In order to satisfy a demand for various shapes of windows of a mobile terminal and manufacture a mobile terminal with a low price, provided is a mobile terminal comprising a display panel and a window assembly disposed on the front surface of the display panel, wherein the window assembly comprises: an outer window forming a front outer appearance; an inner window disposed on the rear surface of the outer window while having a space between the outer window and the inner window; and a resin disposed in the space to fix the outer window to the inner window.

Abstract: An apparatus for measuring transmittance which can realize reliability for measurement of the transmittance of a piece of patterned glass by post dispersion of light. The apparatus includes a light source which is disposed in front of an object that is to be measured, and directs light into the object. An integrating sphere is disposed in the rear of the light source and integrating light incident thereinto. The object is mounted on the front portion of the integrating sphere. A light dispersing part is disposed in the rear of the integrating sphere, and disperses light that has been integrated by and then emitted from the integrating sphere. An optical receiver is disposed adjacent to the light dispersing part, and receives light that has been dispersed by the light dispersing part.

Abstract: A cover substrate for a photovoltaic module and a photovoltaic module having the same, in which light energy is converted into electrical energy. The cover substrate includes a substrate having a raised array pattern on a surface on which light is incident, and an anti-reflection film formed on the surface on which light is incident.

Abstract: A high frequency heating apparatus which heats a substrate by applying high frequency waves. The high frequency heating apparatus includes a high frequency generator which generates high frequency to heat the substrate and a reflector which reflects the high frequency generated by the high frequency generator toward the substrate.

Abstract: A method of tempering glass and an apparatus for tempering glass, in which a heater is used and high frequency is generated. The method includes a heating step of heating a piece of glass using a heater and a high frequency generator and a cooling step of cooling the piece of glass by quenching.
