Abstract:
Provided is a display device. The display device includes: a display panel which includes multiple panel bumps, a flexible circuit film which is connected to the display panel and has a mounted chip, and multiple panel lead bondings which connect the display panel and the chip and are extended in a direction. The panel bumps include first panel bumps which are separated from each other along a first row and second panel bumps which are separated from each other along a second row. Each of the second panel bumps are arranged between two adjacent first panel bumps. The panel lead bondings include a first panel lead bondings connected to the first panel bumps and second panel lead bondings connected to the second panel bumps. Each of the first panel lead bondings have a first part having a first thickness and a second part having a second thickness which is less than the first thickness. The second part is a part adjacent to the second panel bumps.
Abstract:
The present invention provides a device assembly including a chip-on-film. The device assembly includes a film package which includes a semiconductor chip, a panel board which is connected to one end of the film package, a display panel which is arranged on the panel board, and a circuit board which is connected to the other end of the film package. The film package includes a film substrate, a first wire which is arranged on the upper surface of the film substrate, and a second wire which is arranged on the lower surface of the film substrate.
Abstract:
PURPOSE: A tape wiring substrate and a chip on film package including the same are provided to reduce the stress applied to a line pattern by using at least one recess formed in the bending part of a base film. CONSTITUTION: A tape line board(130) includes a base film(110) and a line pattern(120). At least one recess(115) is formed on one surface of the base film. A chip mounting area for a semiconductor chip(140) is formed in the other surface of the base film. A line pattern is formed in the other surface of the base film and extended to the edge of the chip mounting area. A protection layer(160) covers the line pattern.
Abstract:
PURPOSE: A tape package and a display device thereof are provided to decrease heat in a semiconductor chip by forming a bonding layer for heat-sink in one side which the semiconductor chip is arranged and the other side which is faced with the one side. CONSTITUTION: A tape package and a display device thereof comprise a base film(220), a wiring(230), a protective film(240), a semiconductor chip(250), and a bonding layer(280). The base film comprises an insulating film like polyimide or polyester. The wiring is arranged on the single-side of the base film. The protective film is formed on the single-side of the base film and the wirings so that one part of the wirings is exposed. The semiconductor chip is installed on the single-side of the base film and is touched with the exposed parts of the wirings. The bonding layer is arranged in the other side which is faced with the single-side of the base film.
Abstract:
PURPOSE: A method of manufacturing a wiring substrate, a method of manufacturing a tape package and a method of manufacturing a display device are provided to reduce the thermal transformation of substrate and dimensional change of in manufacturing process. CONSTITUTION: The screen(120) having the opening for the wiring formation on the base plate(110) is attached. The conductive paste is spread in the opening for the wiring formation of screen. Substrate is arranged on the screen in which the conductive paste(124) is spread. The conductive paste is hardened and is attached to substrate. The base plate and screen are removed from substrate.
