▎ 摘　　要

NOVELTY - The organic LED screen body with the variable shape has a substrate layer (1), a water-blocking layer (2), an anode layer (3), a light-emitting layer (4), a cathode layer (5), an encapsulation layer (6), a light driving layer (7) and a protection layer (8), which are sequentially arranged along the thickness direction of the organic LED screen body. USE - Organic LED screen body with the variable shape for use in phototherapy applications (claimed) such as wearable phototherapy devices and three dimensional display modules. ADVANTAGE - The shape of the screen body is controlled by light, the three-dimensional organic LED screen body is driven by the light through illumination. The screen body can deform. The phototherapy device is fixed on a human body. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of an organic LED panel.
