Problems solved by technology

[0003] However, in reality, the connection between the FPC and the liquid lens is susceptible to various problems
Positioning errors of the FPC or liquid lens and / or any misalignment of the components may cause a short circuit between one electrode on the liquid lens and another electrode on the FPC
Additionally, positioning or alignment errors may disrupt the conductive electrical contact between corresponding electrodes, thus restricting proper operation of the camera

Abstract

An optical assembly is disclosed which may include a lens having first and second electrodes; and a flexible printed circuit (FPC) configured for placement in proximity to the lens, wherein the FPC may include a bottom insulating layer; a top insulating layer; and an FPC electrode configured to contact the second electrode of the lens, wherein the FPC electrode may include a center portion disposed between the bottom and top insulating layers of the FPC; a post connected to the center portion and extending through the top insulating layer of the FPC; and a contact layer connected to the post and configured to provide the contact with the second electrode of the lens.

Description

technical field [0001] The present invention relates generally to the connections made to the circuitry of a digital imaging device and, in particular, to establishing electrical contact between a lens and one or more electrodes on a circuit board. Background technique [0002] Modern digital cameras may include a lens barrel that includes various components that enable the camera to operate. Among the components included in such a barrel are a lens, which may be a liquid lens, and a flexible printed circuit (FPC). An appropriate connection is required between the FPC and the liquid lens in order to be able to properly acquire image data. Electrical connections are usually successfully achieved when the FPC and lens are optimally positioned relative to each other. [0003] In practice, however, the connection between the FPC and the liquid lens is subject to various problems. Positioning errors of the FPC or liquid lens and / or any misalignment of the components may cause ...
