Zusammenfassung:The invention provides a backplane with adjustable curvature and its application. The backplane includes an active layer and a passive layer connected with the active layer. The active layer is formed by a material with a first thermal expansion coefficient, and the passive layer is formed by a material with a second thermal expansion coefficient. The first thermal expansion coefficient is greater than the second thermal expansion coefficient. It further includes a temperature sensor set on the backplane and a temperature controller electrically coupled to the backplane to adjust the backplane temperature. A fast and continuous adjustment to the curvature of the backplane can be achieved by controlling the temperature of the backplane.
