A method of manufacturing a display device includes preparing a display panel that has a display region where an image is displayed and a non-display region adjacent to the display region, and disposing a power supply flexible printed circuit board (FPCB) in a lower surface of the display panel and in the non-display region of an upper surface of the display panel. The method includes disposing a tape on the display panel to cover an upper side of the power supply FPCB disposed on the upper surface of the display panel, and attaching the tape to the display panel by performing a thermal hardening process on the tape to fix the power supply FPCB to the display panel.
Abstract:
A liquid crystal display device having a touch panel and a front window which can enhance reliability thereof and facilitates repair thereof is provided. The touch panel and the front window are mounted on a liquid crystal display device using a thermoplastic adhesive material. Electronic parts are arranged on a lower side of a touch-panel-use flexible printed circuit board, and electronic parts are arranged on a lower side of a main flexible printed circuit board. The respective electronic parts are covered with the front window in a plan view. A light emitting diode is mounted on the main flexible printed circuit board, and faces a light guide plate in a resin mold. Due to such a constitution, an external shape of the liquid crystal display device can be made small as a whole, and relatively expensive light emitting diodes can be reproduced and reused by repair.

Abstract:
The present invention provides a printed circuit board installed in a lens barrel with an imaging optical system. In an installed state, the printed circuit board comprises: a ring-shaped portion disposed substantially perpendicular to the optical axis of the imaging optical system wherein an aperture is provided at a central portion of the ring-shaped portion so that an imaging light beam may pass through the aperture; and an extending board portion that extends outward from the ring-shaped portion wherein electrical components may be mounted on the surface of the extending board portion. After the ring-shaped portion and the extending board portion have been bent, the above-described flexible printed circuit board is inserted into the lens barrel in such a manner that the plane of the extending board portion on which the electrical components are mounted is parallel to the optical axis of the imaging optical system. This printed circuit board provides high efficiency electrical interconnections in the lens barrel.
