Patent number: 11228008Abstract: The present disclosure relates to a flexible substrate and a flexible display screen. The flexible substrate includes a first bending zone and a non-bending zone. An elastic modulus of the flexible substrate in the first bending zone is smaller than the elastic modulus in the non-bending zone. When the flexible display screen is bent in the first bending zone, since the elastic modulus of the flexible substrate in the first bending zone is smaller than the elastic modulus in the non-bending zone, such that the neutral layer of the first bending zone moves toward a side away from the flexible substrate, thereby reducing the strain on the display unit located on the side of the first bending area, avoiding the breakage of the metal trace and improving the probability of correct operation of the screen.Type: GrantFiled: October 14, 2019Date of Patent: January 18, 2022Assignee: YUNGU (GU'AN) TECHNOLOGY CO., LTD.Inventors: Kun Hu, Hao Feng, Pengle Dang, Lu Rao
