A display device includes: at least two mount members fixable to a wall in a row; and at least two display panels coupleable to the at least two mount members, respectively, and slidable along the at least two mount members. The at least two display panels respectively include: a base; a docking plate, coupleable to a front of the base, having a front surface to which a plurality of display modules of the at least two display panels are coupleable; and a step adjustment member, arrangeable on the base, and so that the docking plate which is coupled to the front of the base is moveable along a front direction or a rear direction of the base to change a distance between the docking plate and the base and adjust front surfaces of adjacent display panels, among the at least two display panels, relative to each other.

Display device

An optical failure detection system includes a test chamber having an accommodating space therein, the test chamber including an upper cover having an opening therein; a substrate plate provided in the opening of the upper cover, the substrate plate including: a first surface on which a wafer is disposed; a second surface opposite to the first surface; and an optical window formed in a central region of the substrate plate and through which the wafer is exposed; a temperature control device including a plurality of thermoelectric devices provided around the optical window of the substrate plate, the temperature control device being configured to heat or cool at least one semiconductor device of the wafer; and an optical device provided in the accommodating space of the test chamber, the optical device being configured to radiate light toward the at least one semiconductor device through the optical window.

Inspection system and inspection method for semiconductor device

A display apparatus includes a frame, a display panel configured to be detachable from the frame, and a position adjustment device provided between the frame and the display panel. The position adjustment device includes a first position adjusting member configured to adjust a position of the display panel in a first direction moving vertically with respect to the frame, and a second position adjusting member configured to adjust the position of the display panel in a second direction moving horizontally with respect to the frame.
