Abstract
A cell manipulation panel includes a pixel array defining multiple pixels, an insulating layer forming multiple vias, and a cell gap provided with a fluid medium having cells therein. Each pixel has a TFT and corresponds to a corresponding via. The TFT includes a gate electrode, a first electrode, and a second electrode partially exposed to the fluid medium through the corresponding via. For each pixel, in an operational mode, when the gate electrode is provided with an OFF signal and the first electrode is not grounded, the TFT is turned off, allowing one of the cells in the fluid medium to be captured in the corresponding via by a dielectrophoresis (DEP) force. When the gate electrode is provided with an ON signal and the first electrode is grounded, the TFT is turned on, and the second electrode is grounded to release the captured cell to the fluid medium.
