Shape-variable electronic device and operation method thereof

The present invention relates to a shape-variable electronic device and an operation method thereof and, more specifically, to a shape-variable electronic device including: a substrate having a cell region; a light source unit on the cell region; and a flexible layer provided vertically spaced apart from the light source unit. The flexible layer includes an actuator unit that changes the shape ofthe flexible layer, and the actuator unit includes: a light-heat response unit configured to receive light emitted from the light source unit and to emit thermal energy; a deformation unit configuredto receive the thermal energy from the light-heat response unit and to reduce mechanical rigidity thereof; and lower and upper electrodes provided on opposite sides of the deformation unit, respectively. 本发明涉及一种形状可变的电子装置及其操作方法，更具体地，形状可变的电子装置包括：基板，具有单元区域；光源单元，位于所述单元区域上；以及柔性层，与所述光源单元竖直地间隔开。所述柔性层包括致动器部，所述致动器部改变所述柔性层的形状，并且所述致动器部包括：光热响应部，接收从所述光源单元发射的光并产生热能；变形部，接收来自所述光热响应部的所述热能，并且所述变形部的机械刚度减小；以及顶电极和底电极，分别位于所述变形部的两个表面上。
