Quantum dot unit, quantum dot sheet having the same, and display apparatus having the quantum dot unit or the quantum dot sheet

Abstract

It discloses an X-ray imaging apparatus comprising X-ray detector, and it has impact resistance. X-ray photographing apparatus includes an X-ray detector is provided for detecting an irradiated X-rays from the x-ray source and the X-ray source for irradiating to generate the X-rays, and the x-ray detector comprises a case having at least one opening, the X-ray irradiation from the X-ray source to a frame which is removably inserted in the interior of the case is provided to convert an electrical signal sensing panel, through the at least one opening, the frame the X-rays from the edge of the body and the body being arranged such that the detection panel may include a plurality of shock-absorbing member is disposed in close contact between the plurality of legs and said case to enclose a plurality of frames, including a leg and a plurality of surfaces of each of said plurality of legs extending in the thickness direction of the detector.
