Abstract: An OLED panel may include a substrate including a first region and a second region disposed along a first direction. A plurality of first pixels are disposed in the first region on the substrate, the first pixels each having a first area, the first pixels each comprising a first unit pixel, a second unit pixel disposed along a second direction from the first unit pixel, and a transmission portion disposed along the first direction from the first unit pixel and the second unit pixel. A plurality of second pixels are disposed in the second region on the substrate, the second pixels each having a second area less than the first area, the second pixels each comprising a third unit pixel. The first unit pixel, the second unit pixel, and the third unit pixel may have substantially the same shape as each other.

Abstract: A quick connector for connection to a complementary counterpart comprises a coupling piece and a retainer for a section of a fluid having a coupling center axis defining an axial direction AD, a radial direction RD and a circumferential direction CD. The retainer is allocated to the coupling end, wherein the retainer has at least one retaining element for retaining the counterpart and at least one actuating element for opening the retainer for pulling the counterpart out of the coupling piece. The coupling piece comprises a first flange at the coupling end, wherein the first flange has a flange opening so as to insert a tool into the flange opening so that the tool can exert a force on the retainer and the actuating element, respectively. The flange opening has an outer border, wherein the outer border lies in radial direction RD outward of the flange opening.
