T-Lens AF module - equipped with Liquid Lens, i.e. T -Lens, which achieves different curvature changes at different voltages, and changing the direction of the incident light to focus on different object distance. Compared with traditional VCM, the AF module has smaller X/Y size, faster focus speed, ultra-low power consumption, no magnetic interference and poor posture. With the improvement of the pixel of the front camera of the mobile phone and the development of the full screen, the demand for miniaturized AF modules in the watch, medical imaging equipment and other industries, the T-Lens AF module came into being and has a broad market prospect.
