Abstract: The invention provides an anisotropic conductive adhesive film and an electronic device. The anisotropic conductive adhesive film comprises a base film and microcapsule structures, wherein the microcapsule structures are set on the base film, and each of the microcapsule structures comprises a metallic conductive particle, a normal-temperature curable macromolecular polymer coated on the outside of the metallic conductive particle and a microcapsule wall coated on the outside of the macromolecular polymer, and an adhesive glue is adhered to the external surface of the microcapsule wall. When in use, the microcapsule structure is destroyed by pressurizing, the conductive particle and the normal-temperature curable macromolecular polymer contained inside the microcapsule wall leak out, and the normal-temperature curable macromolecular polymer leaked out is cured, so that electrical conduction and connection of a microelectronic apparatus can be achieved at normal temperature via the anisotropic conductive adhesive film.

Abstract: The present disclosure discloses a gate driving method, a driving apparatus of a display panel and a display apparatus. The driving apparatus may be in two driving modes, i.e., a first mode and a second mode. In the first mode, due to a reduced number of gate lines to be driven when various frames of images are displayed, the power consumption can be reduced. In addition, due to the effect of persistence of vision of human eyes, better quality of display images can be ensured while reducing power consumption. In the second mode, as respective lines of gate lines are driven progressively when various frames of images are displayed, the display panel is enabled to have better quality of display images. By switching the driving apparatus between the first mode and second mode, a number of gate lines to be driven can be reduced so as to reduce power consumption.
