Abstract: The present application provides a display panel and a display device. The display panel includes a substrate, a pixel definition layer, a light emitting layer, and a cathode layer. The pixel definition layer is disposed on a side of the substrate. The pixel definition layer includes a pixel aperture region and a non-pixel aperture region. The light emitting layer is disposed in the pixel aperture region. The cathode layer includes a black cathode layer. The black cathode layer covers the non-pixel aperture region. The black cathode layer is configured to absorb light to improve contrast and color purity of the display panel and the display device.

Abstract: A display panel and a display device are provided. The display panel includes a first display area and a second display area corresponding to a position of an electronic component, wherein a light transmittance of the second display area is greater than a light transmittance of the first display area. A plurality of pixel units are disposed in the second display area, a ratio of a number of the first sub-pixels to the second sub-pixels and the third sub-pixels is 1:1:2 in each of the pixel units of the second display area, and by providing pixels with larger intervals in the second display area, a light transmittance above the electronic component is increased.

Abstract: A pixel structure and a display device are provided. The pixel structure is designed and arranged in this way, which is helpful for simplifying a layout design of data lines. In addition, this can reduce dependence on a compensation circuit in a driving circuit. Further, arrangements and shapes of first sub-pixels and second sub-pixels are same. Therefore, a set of masks can be used to make the first sub-pixels and the second sub-pixels together, thereby reducing the mold charge of the masks and saving costs.

Abstract: An organic light emitting diode display panel and a method of manufacturing thereof. The organic light emitting diode display panel includes a substrate, a driving circuit layer, an organic light emitting diode layer, and a thin film encapsulation layer, which are disposed in order. The thin film encapsulation layer extends through the third through hole disposed on the organic light emitting diode layer and covers the organic light emitting diode layer.
