(EN) LIQUID LENS MODULE AND CAMERA MODULE COMPRISING SAME
(FR) MODULE DE LENTILLE LIQUIDE ET MODULE DE CAMÉRA LE COMPRENANT
Abstract
(EN)
Provided according to an embodiment is a liquid lens module comprising: a first housing including a first hole for coupling a first lens unit; a lower connection substrate coupled to the first housing; an upper connection substrate disposed on the lower connection substrate and coupled to the first housing; and a liquid lens disposed between the lower connection substrate and the upper connection substrate and electrically connected to the lower connection substrate and the upper connection substrate, wherein the first substrate includes an opening larger than the size of the liquid lens, the opening being disposed at a position corresponding to the first hole in the optical axis direction.
