A measurement device includes a power supplier including a first terminal through which a first power voltage is output and a second terminal through which a second power voltage is output, the power supplier being configured to receive a first current from the first terminal to measure a power current of a display device and to receive a second current from the second terminal to measure a luminance of the display device; a switching circuit including a first switch configured to selectively connect a power terminal of the display device to the first terminal or an internal voltage terminal of the display device through which an internal voltage of the display device is output; and a luminance sensing circuit configured to receive the second power voltage and to generate the second current corresponding to the luminance of the display device.

Measurement device and measurement method thereof

A display device includes a first display panel, a second display panel, and an optical member. The first display panel includes a first substrate and a first cover member on the first substrate. The second display panel is coupled to a first side of the first display panel, and includes a second substrate and a second cover member on the second substrate. The optical member is in a groove defined by the first and second cover members at a boundary of the first and second display panels.

Display device including coupled display panels

A display device includes: first and second substrates; adjacent first and second color filter layers between the first and second substrates and having a first color; adjacent third and fourth color filter layers between the first and second substrates and having a second color; first and second dummy color filter layers between the first color filter layer and the second color filter layer and having the first and second colors, respectively; a first column spacer between the first dummy color filter layer and the second substrate; and a second column spacer between the second dummy color filter layer and the second substrate. The first dummy color filter has a greater height than the second dummy color filter layer. A surface of the first dummy color filter layer facing the second substrate is larger than that of the second dummy color filter layer.

Display device and method for fabricating the same

A tile display device includes element display devices, each including an element display panel which defines a display area and a panel driver disposed on a seam area surrounding the display area, and a coupling display device disposed on element display devices and coupled to the element display devices at neighboring seam areas. The coupling display device includes a boundary display panel on the neighboring seam areas, a coupler which couples the boundary display panel to the element display panels to provide a coupling panel structure, a boundary driver which drives the boundary display panel and a signal control center which drives the coupling panel structure.

Coupling display device and tiled display device having the same

A display panel includes a first display substrate, a second display substrate facing and spaced apart from the first display substrate, a non-conductive sealing member disposed between the first display substrate and the second display substrate and formed around an outer perimeter of the display panel, a conductive sealing member disposed inside the non-conductive sealing member when viewed in a plan view, and a connection pad coupled to a side surface of the first display substrate and a side surface of the non-conductive sealing member. A signal line includes an end portion overlapping with the non-conductive sealing member and connected to the connection pad.
