Abstract: A lens module comprises a housing, a lens holder movably accommodated in the housing and an optical image stabilization device (OIS device). The OIS device is configured to generate a driving force according to the movement of the lens holder so as to stabilize the lens holder. The OIS device of the lens module further comprises a substrate and a plurality of driving coils received in the substrate by means of embedment so that the OIS device occupies a smaller proportion of space in the lens module and thereby to keep the lens module compact.

Abstract: An optical element driving mechanism is provided, including a fixed portion and a movable portion. The movable portion moves relative to the fixed portion. The movable portion includes a first movable assembly and a second movable assembly. The first movable assembly is connected to a first optical element. The second movable assembly is connected to a second optical element. The first movable assembly and the second movable assembly are movable relative to each other. The fixed portion further includes a first guiding element and a second guiding element. The first guiding element guides the first movable assembly and the second movable assembly to move in a first dimension. The second guiding element guides the first movable assembly and the second movable assembly to move in the first dimension. The first guiding element and the second guiding element are located at opposite corners of the fixed portion.
