Disclosed are a physical feedback system, a control method and device, a display assembly and an electronic device, which belong to the field of display screens. The system comprises: at least one physical feedback unit located below a flexible touchscreen; the physical feedback unit comprises an armature part and a coil part, wherein at least one of the armature part and the coil part is in an active state, and the initial relative distance between the armature part and the coil part is a predetermined value; when the coil part is energized, the relative distance between the armature part and the coil part is changed under the action of electromagnetism, and the changed relative distance is greater than or smaller than the predetermined value, so that a bulge or a depression is formed in the corresponding location of the flexible touchscreen. This disclosure solves the problem that the response time is too long when using a charged liquid medium for implementation; and achieves the effects of being able to rapidly physically deform the flexible touchscreen by only energizing the coil part, and of shortening the response time. |
