DIGITAL MICRO-FLUIDIC CHIP AND DRIVING METHOD THEREFOR, AND DIGITAL MICRO-FLUIDIC APPARATUS

摘要

A digital micro-fluidic chip and a driving method therefor, and a digital micro-fluidic apparatus. The digital micro-fluidic chip comprises an optical driving layer (20) and a state switching layer (30). The state switching layer (30) is used for bearing a liquid drop (100). The optical driving layer (20) is used for providing a light ray for controlling the state switching layer (30) to perform lyophilic and lyophobic switching so as to drive the liquid drop (100) to move. The optical driving layer (20) comprises multiple light-emitting units arranged in an array. By using the optical driving layer (20) which provides a light ray and the state switching layer (30) capable of performing the lyophilic and lyophobic switching, the optical driving layer (20) is enabled to control, by providing a light ray, the state switching layer (30) to perform the lyophilic and lyophobic switching, so as to drive the liquid drop (100) to move.
