Abstract:
Provided are a chip-on-film (COF) package and a device assembly including the same. The device assembly includes a COF package including a film substrate on which a plurality of film-through wires are formed. The device assembly includes a panel unit including a panel substrate on which a plurality of panel-through wires are formed. The panel unit is disposed on the COF package. One end of the panel unit is electrically connected to a first end of the COF package. The device assembly includes a control unit disposed below the panel unit. One end of the control unit is electrically connected to a second end of the COF package.
Abstract:
Chip-on-film packages and device assemblies including the same may be provided. The device assembly includes a film package including a semiconductor chip, a panel substrate connected to one end of the film package, a display panel disposed on the panel substrate, and a controlling part connected to another end of the film package. The film package includes a film substrate, a first wire disposed on a top surface of the film substrate, and a second wire disposed on a bottom surface of the film substrate.
Abstract:
A COF substrate may include a base film, first upper conductive patterns, at least one second upper conductive pattern and lower conductive patterns. The first upper conductive patterns may be arranged on an upper surface of the base film. Each of the first upper conductive patterns may have an inner pattern and an outer pattern spaced apart from each other. The second upper conductive pattern may be arranged on the upper surface of the base film between the first upper conductive patterns. The lower conductive patterns may be arranged on a lower surface of the base film. The lower conductive patterns may be electrically connected between the inner pattern and the outer pattern. Thus, conductive materials causing a short between the panel patterns may not exist between the inner pattern and the outer pattern on the upper surface of the base film.
Abstract:
A tape film package is provided including an insulating pattern; a via contact in a via hole in the insulating pattern; first interconnection patterns extending from the via contact to a cutting surface of the insulating pattern; and second interconnection patterns connected to the via contact below the insulating pattern. The second interconnection patterns are parallel to the first interconnection patterns and spaced apart from the cutting surface of the insulating pattern.
