摘要:
A test device for a display panel and a method of testing the same are provided. The test device for a display panel includes a luminance measurement unit that measures a luminance value of a display panel including a plurality of pixels, and a controller that determines a voltage value of a data signal corresponding to a target luminance value, receives a measured luminance value of a pixel to which the data signal is supplied from the luminance measurement unit from among the plurality of pixels, compares the measured luminance value and the target luminance value, and outputs a control signal that changes a first power source voltage value supplied from a power source voltage supply unit to the pixel until the measured luminance value does not coincide with the target luminance value.

An organic light-emitting display apparatus including first and second edge sub-pixel lines disposed at opposing side edges of the apparatus and center sub-pixel lines disposed therebetween, each for emitting a single color of light. An external emission width of the first edge sub-pixel line is less than an external emission width of the center sub-pixel lines that emit the same color. An external emission width of the second edge sub-pixel line is less than the width of the center sub-pixel lines that emit the same color.

A touch screen panel includes a transparent substrate. A plurality of first and second sensing cells are formed so as to be connected along first and second directions, respectively. The second sensing cells are disposed between the first sensing cells. A plurality of first and second connection patterns connect the first and second sensing cells to one another along the first and second directions, respectively. A first insulating layer is interposed between the first second connection patterns. In the touch screen panel, each of the first connection patterns includes a main bridge pattern separately patterned in a different layer from the first sensing cells connected by the main bridge pattern to connect adjacent first sensing cells to other along the first direction, and one or more sub-bridge patterns which branch from the main bridge pattern, and which have both ends connected to the main bridge pattern so as to form a detour path.

A flat panel display apparatus includes: a first substrate, a second substrate opposite the first substrate and including a display region in which a plurality of pixels are formed, and a sealing member between the first substrate and the second substrate; the sealing member bonds the first substrate and the second substrate to each other. The sealing member overlaps at least a part of outermost pixels of the display region.

An organic electroluminescent display device (OELD) that prevents particles from creating blind spots by forming a recess or a groove in the surface of an insulating layer that covers edges of a pixel electrode. The OELD includes a lower electrode arranged on a substrate, an insulating layer arranged on the substrate, the insulating layer having an aperture adapted to expose a portion of the lower electrode, an organic layer arranged on the exposed portion of the lower electrode, and an upper electrode arranged on the substrate, wherein the insulating layer includes a recess and/or a groove in its surface.

A touch screen panel comprises a first sensing pattern provided with first sensing cells arranged on one row along a first direction on a transparent substrate, and a first connection pattern through which adjacent first sensing cells are electrically connected to each other. A second sensing pattern is provided with second sensing cells arranged so as to be spaced apart from the first sensing cells on one column along a second direction on the transparent substrate, and a second connection pattern through which adjacent second sensing cells are electrically connected to each other. The first connection pattern includes at least two pairs of metal patterns arranged so as to be spaced apart from one another, and a transparent pattern formed in the shape of an island in the second sensing pattern so as to be electrically connected to one or the other end of each of the metal patterns.
