Abstract
The invention provides a cover plate structure, a manufacturing method of the cover plate structure and a display device. A first absorption layer and a second absorption layer are stacked on one side of a cover plate main body in the cover plate structure; the first absorption layer and the second absorption layer form a transparent absorption layer; the orthographic projection of the transparent absorption layer on the cover plate main body is overlapped with a light-transmitting area of the cover plate main body; the transparent absorption layer can absorb ultraviolet rays in light rays penetrating through the light-transmitting area of the cover plate main body, so that the situation that the brightness of the display device is reduced due to the fact that the ultraviolet rays penetrate through the cover plate and then irradiate a light-emitting material in an OLED display module is avoided, and the display quality of the OLED display device is guaranteed. In addition, the transparent absorption layer can also convert the energy of the ultraviolet rays into electric energy, and power supply to the OLED display device can be realized.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a cover structure, a manufacturing method of the cover structure, and a display device. Background technique [0002] The OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display device has the advantages of high brightness, low power consumption, wide color gamut, fast color change reflection rate, etc., and its application is becoming more and more extensive. At the same time, due to its relatively thin and flexible characteristics, OLED display devices have been used in wearable devices such as watches and bracelets. [0003] The OLED display device includes an organic light-emitting material, and the organic light-emitting material is electrically driven to make it emit light. However, organic light-emitting materials are prone to chemical changes after being exposed to external light for a long time, resulting...
