  • Patent number: 11940421
    Abstract: A method and an apparatus for detecting bending stiffness and a method for testing a display panel. The method for detecting bending stiffness includes: arranging an object to be tested on a reference surface to make a stationary portion and a rotating portion of the object to be tested attached to the reference surface, the stationary portion and the rotating portion being connected to each other; driving the rotating portion to bend from the reference surface toward the stationary portion, and acquiring a rotation angle between the rotating portion and the reference surface; acquiring a bending force received by the rotating portion when the rotating portion is bent from the reference surface toward the stationary portion; and determining bending stiffness of the object to be tested on the basis of the bending force and the rotation angle.

  • Publication number: 20220190299
    Abstract: A display panel and a display apparatus. The display panel includes: a screen body including a display surface and a non-display surface opposite to the display surface; a support film disposed on a side of the screen body having the non-display surface; a composite tape disposed on a side of support film away from the screen body; a first reflective film disposed in a same layer with the support film and/or the composite tape. A position of the first reflective film corresponds to a perforated region of the display panel. The position of the perforated region corresponds to a position of an external optical or acoustic module. A possibility of a Mura phenomenon occurring on an image displayed on the display panel at a position corresponding to the perforated region may be reduced.

  • 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.
