Abstract
An apparatus includes a first circuit board, a driving chip, and a second circuit board. The driving chip is coupled to the first circuit board, and the second circuit board is spaced apart from and electrically connected to the driving chip. At least part of the second circuit board is spaced apart from a first surface of the first circuit board.
Claims21
An apparatus, comprising:
- a first circuit board including first signal lines and second signal lines;
- a driving chip coupled to the first circuit board;
- and
- a second circuit board spaced apart from and electrically connected to the driving chip, wherein the second circuit board is a flexible circuit board and wherein at least part of the second circuit board is spaced apart from a first surface of the first circuit board in a bridge structure, each of the first signal lines has different sub-lines that are spaced apart from one another and located on different insulation layers, a portion of a second insulation layer having a smaller size than a first insulation layer to expose a portion of the first insulation layer, the exposed portion of the first insulation layer including a pad area.
