Flexible film, circuit board assembly including the same and display apparatus including the same

A circuit board assembly comprising:

• a circuit board which provides a signal;
• and
• a flexible film which is attached to and receives the signal from the circuit board,
• wherein the flexible film comprises:
• a base film comprising an edge portion which extends in a first direction;
• a plurality of wirings disposed on the base film;
• and
• a plurality of pads which is disposed in the edge portion of the base film and connected to the plurality of wirings,
• wherein the plurality of pads disposed in the edge portion comprise:
• a plurality of horizontal pads horizontally arranged in the first direction to define a pad row extended in the first direction;
• and
• a vertical pad comprising a plurality of vertically arranged pads arranged in a second direction perpendicular to the first direction,
• wherein the plurality of vertically arranged pads are disposed between a h-th horizontal pad and a (h+1)-th horizontal pad among the plurality of horizontal pads, where the h is a natural number.

A display apparatus comprising:

• a display panel which generates and displays an image with a signal provided thereto;
• a circuit board which provides the signal;
• and
• a flexible film which is attached to the display panel and the circuit board and through which the signal passes from the circuit board to the display panel,
• wherein the flexible film comprises:
• a base film comprising an edge portion which extends in a first direction;
• a plurality of wirings disposed on the base film;
• and
• a plurality of pads which is disposed in the edge portion of the base film and connected to the plurality of wirings,
• wherein the plurality of pads disposed in the edge portion comprise:
• a plurality of horizontal pads horizontally arranged in the first direction to define a pad row extended in the first direction;
• and
• a vertical pad comprising a plurality of vertically arranged pads arranged in a second direction perpendicular to the first direction,
• wherein the plurality of vertically arranged pads are disposed between a h-th horizontal pad and a (h+1)-th horizontal pad among the plurality of horizontal pads, where the h is a natural number.

A flexible film comprising:

• a base film defining an edge of the flexible film which extends in a first direction, in a top plan view;
• and
• a plurality of pads disposed on the base film, through which an electrical signal is input to the flexible film or output from the flexible film, and which are arranged along a single line in the first direction within a single pad row along the edge of the flexible film,
• wherein for the plurality of pads arranged in the single pad row,
• the base film comprises a plurality of individual pad areas in which a pad is disposed on the base film, the individual pad areas arranged spaced apart from each other in the first direction within the single pad row, and
• a total number of the pads arranged in the single line is smaller than a number of the plurality of individual pad areas in the single pad row,
• wherein the plurality of pads comprise:
• a plurality of horizontal pads horizontally arranged in the first direction to define a pad row extended in the first direction;
• and
• a vertical pad comprising a plurality of vertically arranged pads arranged in a second direction perpendicular to the first direction,
• wherein the plurality of vertically arranged pads are disposed between a h-th horizontal pad and a (h+1)-th horizontal pad among the plurality of horizontal pads, the h is a natural number.

A flexible film comprising:

• a base film defining an edge of the flexible film which extends in a first direction;
• a plurality of wirings disposed on the base film, and
• a plurality of pads arranged in the first direction within a pad row at the edge of the flexible film and connected to the plurality of wirings,
• wherein for a same pad row,
• a maximum pad length extending in a second direction perpendicular to the first direction, among the plurality of pads in the same pad row, defines a boundary of the same pad row in the second direction, and
• within the boundary in the second direction of the same pad row, the plurality of pads comprise:
• a plurality of horizontal pads horizontally arranged in the first direction;
• and
• a vertical pad comprising a plurality of vertically arranged pads arranged in the second direction,
• wherein the plurality of vertically arranged pads are disposed between a h-th horizontal pad and a (h+1)-th horizontal pad among the plurality of horizontal pads, where the h is a natural number.
