Abstract

A display device manufacturing apparatus includes a support portion including a core portion and a conductive portion disposed over the core portion. The core portion includes a first flat surface extending in a first direction; a second flat surface extending in the first direction and being opposite to the first flat surface; and a curved surface extending between the first flat surface and the second flat surface. The conductive portion includes a first flat conductive portion overlapping the first flat surface of the core portion in a second direction; a second flat conductive portion overlapping the second flat surface of the core portion in the second direction; and a curved conductive portion extending between the first flat conductive portion and the second flat conductive portion.

Claims9

Dependent claims

A display device manufacturing method comprising:

disposing a display panel over a support portion including a first flat support portion, a second flat support portion opposing the first flat support portion, and a curved support portion extending between the first flat support portion to the second flat support portion, the support portion including a core portion and an electrically conductive portion disposed over the core portion;
disposing a magnetic portion that partially surrounds the support portion, the magnetic portion being capable of conducting an electric current, wherein in response to electric current flowing in the magnetic portion, an electrostatic attractive force is formed between the magnetic portion and the conductive portion, causing at least one part of the magnetic portion to move towards an overlapping part of the conductive portion;
forming a curved display panel, including:
forming a first flat panel portion corresponding to the first flat support portion;
forming a second flat panel portion corresponding to the second flat support portion;
and
forming a curved panel portion corresponding to the curved support portion;
disposing a curved window over the curved display panel to be spaced apart from the curved display panel, the disposing of the curved window including:
disposing a first flat window portion corresponding to the first flat panel portion;
disposing a second flat window portion corresponding to the second flat panel portion;
and
disposing a curved window portion corresponding to the curved panel portion;
and
attaching the curved display panel to the curved window by an electrostatic attractive force between the magnetic portion over the curved window and the conductive portion of the support portion.
