Embodiment Construction
[0025] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments that the present application can be used to implement. The directional terms mentioned in this application, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are for reference only The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the application, but not to limit the application. In the figures, structurally similar elements are denoted by the same reference numerals. In the drawings, the thicknesses of some layers and regions are exaggerated for clear understanding and ease of description. That is, the size and thickness of each component shown in the drawings are arbitrarily shown, but the present application is not limited thereto.
[0026] Please refer to Figure 1 to Figure 3 , figure 1 A schematic cross-sectional structure diagr...

The invention provides a display panel and an electronic device.The display panel is provided with a flat panel display area and a curved surface display area located on the peripheral side of the flat panel display area, and the display panel comprises a display substrate and a light shielding layer arranged in the light emitting direction of the display substrate; the display substrate comprises a plurality of pixel units which are arranged in a plane display area and a curved surface display area in an array mode, each pixel unit comprises at least three sub-pixels which are arranged at intervals and are different in color, openings are formed in the positions, corresponding to the sub-pixels, of the light shielding layer, and for at least one sub-pixel of the same color, the sub-pixels of the same color are different in color. The size of the opening corresponding to the curved-surface display area is larger than that of the opening corresponding to the flat-surface display area, the brightness attenuation of the curved-surface display area can be slowed down by increasing the opening of the shading layer of the curved-surface display area, and then the brightness of the curved-surface display area is improved; the technical problem that the brightness of a curved surface area of an existing curved surface display device is low is solved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a display panel and an electronic device. Background technique [0002] With the development of display technology, organic light-emitting devices (organic light-emitting devices, OLEDs) are widely used in various electronic devices. In order to realize a full-screen display, the existing organic electroluminescent device will take advantage of its flexible characteristics to set it as a foldable display device or a curved display device, and make the curved surface (Curve) area also realize display, so as to improve The screen-to-body ratio of the display area. At the same time, in order to reduce the thickness of the display device and make it easier to bend or fold, COE (Color film on Encapsulation, color film on the encapsulation layer) technology has emerged to replace the existing thicker polarizer. However, in such a full-screen design, the curved surface area...
