  • Publication number: 20240144874
    Abstract: The embodiments of the application provide a display panel and a driving method thereof and a display apparatus. The display panel includes a first pixel circuit and first light emitting element. The first pixel circuit is electrically connected with M first light emitting elements which are connected in series, M?2 and M is an integer. The first pixel circuit includes: a driving module configured to drive the first light emitting elements to emit light; and at least one first switch module connected in parallel with N first light emitting elements, 1?N<M and N is a positive integer.

  • Publication number: 20230410734
    Abstract: A display panel includes a light-emitting element and a pixel circuit electrically connected to each other. In an embodiment, at least one light-emitting phase of the pixel circuit each includes n light-emitting sub-phases, and the pixel circuit is configured to transmit a light-emitting signal to the light-emitting element in at least one of the n light-emitting sub-phases. In an embodiment, a duration ti of transmitting the light-emitting signal to the light-emitting element by the pixel circuit in the ith light-emitting sub-phase of the n light-emitting sub-phases is smaller than a duration tj of transmitting the light-emitting signal to the light-emitting element by the pixel circuit in the jth light-emitting sub-phase of the n light-emitting sub-phases, where 0<ti, 0<tj, 1?i?n, l?j?n, and i?j.

  • Publication number: 20220238850
    Abstract: The present disclosure relates to a display panel and a display device. The display panel includes a display module, at least one color layer, and a light absorption layer. The display module has a display face and a non-display face opposite to the display face. The at least one color layer is disposed at a side of the display module away from the display face. The light absorption layer disposed at a side of the at least one color layer away from the display module. A first through hole is defined in the light absorption layer. A second through hole is defined in the at least one color layer. The second through hole is located corresponding to and in communication with the first through hole. The first through hole and the second through hole are located corresponding to an external functional module.

  • 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: 11295678
    Abstract: Disclosed in the present disclosure are a picture compensation method and a display apparatus, the picture compensation method, including: obtaining a ratio of non-luminous pixels in an Nth scanning line to all pixels in the Nth scanning line; for each non-luminous pixel in the Nth scanning line, receiving or presetting a first data voltage; obtaining a second data voltage received or preset by a pixel in at least one of an N?1th scanning line and an N+1th scanning line located in a same column with the non-luminous pixel; in response to a transition relationship between the first data voltage and the second data voltage existing, obtaining a voltage value to be compensated for luminous pixels in the Nth scanning line based on the transition relationship and the ratio; and displaying a picture after compensating the voltage value of the luminous pixels in the Nth scanning line of pixels.
