Honor has recently announced a new patent for a liquid lens that has the potential to reduce the size of camera modules, thereby contributing to the miniaturization of electronic devices.
As per a report on July 3, Glory Terminal Co., Ltd. has applied for a patent for “a liquid lens, camera module and electronic equipment,” which can help reduce the internal space occupied by camera modules, leading to the slimming and lightening of electronic devices.
According to the patent abstract, the liquid lens comprises a base, a coating layer, a flexible medium, and an actuating mechanism. The base includes an accommodating cavity, while the coating layer covers the cavity to form a closed cavity. The flexible medium is put inside the closed cavity for the transmission of light.
The actuating mechanism deforms the coating layer to change the shape of the closed cavity, thereby changing the focal length of the liquid lens. This allows the liquid lens to adjust the focal length without needing a motor.
When applied to the camera module, the liquid lens eliminates the need for components like motors, which contributes to the miniaturization of the camera module. This, in turn, reduces the internal space occupied by electronic equipment, leading to the slimming and lightening of such devices.
Typically, camera modules consist of lenses, motors, optical filters, chips, and printed circuit boards stacked together, leading to a considerable height.
However, a camera module with significant height occupies the internal space of the electronic device, making it difficult to achieve the slimming and lightening of electronic devices.
