  • Flexible display module having a flexible glass layer
    Patent number: 11302889
    Abstract: A flexible display module and a method for manufacturing the same solve a problem that the existing flexible display module is easy to be failure after being bent. The flexible display module includes: a flexible glass layer; and a display panel disposed inside the flexible glass layer.
    Type: Grant

  • Flexible substrates and flexible display screen
    Patent number: 11228008
    Abstract: 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.
