  • Patent number: 11957006
    Abstract: A display device includes a display panel and an integrated circuit chip configured with a plurality of first bonding terminals spaced apart from each other. The display panel is provided with a plurality of second bonding terminals, and a first insulating layer is disposed between the first bonding terminals and the second bonding terminals. A plurality of electrically conductive particles are provided on the second bonding terminals and penetrate the first insulating layer so that the electrically conductive particles are in contact with the first bonding terminals.
    Type: Grant

  • Patent number: 11930687
    Abstract: An organic light emitting diode (OLED) display panel and a display device are provided. The OLED display panel includes a light emitting functional layer and a display area disposed on a transistor array substrate. The reinforcement layer is formed on a surface of a bending area of the transistor array substrate. A blocking member is formed on a surface of the transistor array substrate and located between the reinforcement layer and the light emitting functional layer. By providing the blocking member, the control accuracy of the amount of glue overflow in the bending area is improved.

  • Patent number: 11930692
    Abstract: The present application provides a display panel, a display module, and a display device. A flexible substrate of the display panel includes a first flexible substrate and a second flexible substrate, and the first flexible substrate is provided with a first through-hole corresponding to a lighting path of an electronic component. Based on the first through-hole, light transmittance of the display panel is increased, so that electronic components such as a camera can be disposed below the display panel, and a narrow bezel design is realized.
