    摘要： A display panel and a display device are provided in embodiments of the present application. The display panel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel with different light-emitting colors. The first sub-pixel and the second sub-pixel are sequentially arranged along a first direction. The third sub-pixel is arranged on at least two sides of an area where the first sub-pixel and the second sub-pixel are located. The third sub-pixel is a sub-pixel with a shortest light-emitting lifespan in the pixel unit. Such design can make a pixel area ratio of the third sub-pixel be increased in a unit pixel area, reducing a current density of the third sub-pixel and reducing its decay speed, so that the lifespan of the third sub-pixel matches with lifespan of the first sub-pixel or the second sub-pixel.

    摘要： A display panel can include a plurality of subpixels disposed on a substrate and configured to display an image; a plurality of light-emitting elements disposed on the substrate and configured to emit light; and a plurality of light-receiving elements disposed on the substrate and configured to receive reflected light based on the light emitted by the plurality of light-emitting elements, in which the plurality of light-emitting elements or the plurality of light-receiving elements are disposed between the plurality of subpixels. The plurality of light-emitting elements can emit infrared laser light and the plurality of light-receiving elements are configured to generate a three-dimensional map for recognizing a face of a user based on the infrared laser light emitted by the plurality of light-emitting elements.

    摘要： An object of the present invention is to provide a display device capable of achieving both an effect of preventing reflection of external light and improvement in utilization efficiency of light emitted from a light emitting element. An electroluminescent display device includes a substrate having a plurality of light emitting elements using electroluminescence, a λ/4 wavelength plate, and a polarizing plate including a patterned polarizing layer in this order, in which the patterned polarizing layer has a region A having a polarization degree of less than 80% and a region B having a polarization degree of 80% or more, and further, a position of the region A of the patterned polarizing layer corresponds to a position of the light emitting element of the electroluminescent substrate.

    摘要： A display device a display panel including a plurality of light emitting areas; a first optical electronic device located under the display panel; and a second optical electronic device located under the display panel. Further, a first optical area of the display panel overlapping the first optical electronic device includes a plurality of first light transmission areas in addition to the plurality of light emitting areas, a second optical area of the display panel overlapping the second optical electronic device includes a plurality of second light transmission areas in addition the plurality of light emitting areas, a third optical area of the display panel not overlapping the first and second optical electronic devices includes the plurality of light emitting areas without including the first and second light transmission areas, and the first light transmission areas have a different shape or size than the second light transmission areas so a light transmittance of incident light through the first light transmission areas is different than a light transmittance of incident light through the second light transmission areas.
