  • Publication number: 20250151590
    Abstract: A display panel and a display device are disclosed. The display panel includes a substrate, a light-emitting element layer, a pixel defining layer, an encapsulation layer, a refraction layer, and a color filter layer. The refraction layer is arranged on the encapsulation layer to refract light entering the refraction layer. The color filter layer is arranged on the refraction layer, and includes a black matrix disposed in a non-opening area and multiple color filters disposed in a non-opening area. Every two adjacent color filters are separated by the black matrix. The refraction layer includes multiple refraction portions. Each refraction portion is arranged under the black matrix, is located in the non-opening area, and extends toward the opening area. The refraction portions are each used to refract the external ambient light and receive the reflected light reflected by the light-emitting element and refract the reflected light to the black matrix.

  • Publication number: 20250138379
    Abstract: A display panel, a display device, and an electronic device are disclosed. The display panel includes a flexible substrate, a plurality of pixel islands, an electrochromic layer, and a plurality of force sensors. In response to a stretching length of a corresponding one of a plurality of flexible connection lines being greater than a preset value, each of the plurality of force sensors is configured to enable the electrochromic layer to be switched to a transparent state to allow light emitted from the display panel to pass therethrough. In response to the stretching length of the corresponding one of the plurality of flexible connection lines being less than the preset value, each of the plurality of force sensors is configured to enable the electrochromic layer to be switched to an opaque state to block the light emitted from the display panel.

  • Publication number: 20250008828
    Abstract: This application discloses a display panel and a display device. There is a fingerprint recognition region in the display area. A fingerprint recognition element is disposed in the display panel correspondingly below the fingerprint recognition region. The display panel includes an organic light-emitting layer and a color filter layer arranged on a light-emitting side of the light-emitting layer. The color filter layer includes a first black matrix and a color filter. The first black matrix is disposed corresponding to the fingerprint recognition region. Adjacent color filters are separated by the first black matrix. The first black matrix includes carbon black filaments, which are in the shape of elongated strips. Each carbon black filament has a length that lies in the range of 100 nm to 1000 nm and a diameter range that lies in the range of 1 nm to 100 nm.

  • Publication number: 20240363643
    Abstract: Some embodiments of the present disclosure provide an array substrate and a display pane. Multiple pixel electrode branches in a corresponding one of the pixel regions are divided into a first pixel electrode branch and a second pixel electrode branch by a corresponding one of the metal common electrodes. The first pixel electrode branch and the second pixel electrode branch, which are located in different pixel regions and which are adjacent to each other, are respectively connected to different drains of the same TFT. In each pixel region, an end of the first pixel electrode branch close to a corresponding one of the scan lines is connected to a corresponding one of the TFTs, and an end of the second pixel electrode branch close to another corresponding one of the scan lines is connected to another corresponding one of the TFTs.
