  • Patent number: 11651724
    Abstract: Disclosed is an electroluminescent display panel and a display device, and relates to the field of display technologies. The display region comprises a photosensitive device arranging region, a camera or fingerprint recognition device is arranged in the photosensitive device arranging region, rather than in the frame, and thus a relatively larger area occupying in the frame is avoided, to allow the frame be made narrower, and the screen-to-body ratio be increased. Also for the photosensitive device arranging region, the first signal lines and the second signal lines are arranged more intensively by arranging overlap areas in the orthographic projection of one first pixel on the base substrate, to allow the display panel have more concentrated space as the light-transmission region, so that the light transmittance of the photosensitive device arranging region can be increased to provide more lights to the camera or fingerprint recognition device.

  • Patent number: 11372499
    Abstract: A touch display panel and a touch display device including an array substrate, a light-emitting layer, an encapsulation layer, and a touch function layer are provided. The array substrate includes a first trace. The touch function layer includes a second trace. The second trace is electrically connected to the chip by a bonding end, in which the chip is integrated with functions of display control and touching control. This realizes a control of a display function and a touch function of the touch display panel or the touch display device, thereby reducing the number of chips. At the same time, the stepped structure of the edge of the encapsulation layer effectively alleviates the steep gradient between the touch function layer and the array substrate, thereby facilitating the electrical connection of the trace on the touch function layer to the trace on the array substrate.
