Description
Technical Field
The embodiment of the disclosure relates to the technical field of display, in particular to a display device and electronic equipment.
Background
At present, a flexible display device usually comprises at least a display panel, a flexible cover plate, and a polarizer. In order to ensure good flexibility, especially a large curvature type, foldable or rollable display device, the flexible cover plate is usually made of a polymer material, but the polymer material has low strength and is easy to scratch, resulting in poor display effect or experience of the flexible display device. The flexible cover plate is usually adhered to the display panel packaging layer by an adhesive, and if the flexible cover plate is damaged and needs to be taken down for replacement, the lower layer material such as the packaging layer can be damaged and influenced, such as breakage and the like, and the display device is difficult to repair or restore at the moment and can be permanently influenced.
In addition, in the conventional flexible display device, the cathode in the display panel is usually made of a metal material with good conductivity, such as silver, and the metal material has a high reflectivity, such as that the reflectivity of silver in the visible light band reaches over 90%, so that the external ambient light is easily reflected, and the visibility of the display is reduced, which affects the display quality. To reduce or eliminate the effect of ambient light on the visibility of the display, it is necessary to add, for example, a circular polarizer in the stack of the display device to absorb the ambient light. However, the polarizers are thick and are susceptible to moisture and failure, and the development trend of the current flexible display technology is towards thinning, and the use of the polarizers leads to thickness increase and does not meet the trend. Accordingly, there is a need to ameliorate one or more of the problems with the related art solutions described above.
It is noted that this section is intended to provide a background or context to the embodiments of the disclosure that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.

The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.
First, a display device is provided in the present exemplary embodiment. Referring to fig. 1, the display device 100 may include a display panel 10, a flexible cover 20, and a replaceable cover 30; wherein, the flexible cover plate 20 is disposed on the upper surface of the display panel 10.
