Abstract
The present invention provides a cover window structure, comprising a transparent substrate and a hard coating disposed on the transparent substrate; wherein, the region near the contact surface between the transparent substrate and the hard coating is exchanged by molecules A molecular exchange layer is formed by means, and the hardness of the molecular exchange layer is greater than that of the transparent substrate and less than that of the hard coating; the present invention also provides an OLED display device prepared by using the above-mentioned cover window structure. The present invention uses the structure design of the cover window, which can effectively improve the bending resistance of the cover window structure.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a cover window structure and an OLED display device. Background technique [0002] With the introduction of new era / high-performance electronic products, flexible and bendable consumer electronics have attracted investment and development from various major manufacturers. In order to achieve dynamic bending and foldable OLED (Organic Light-Emitting Diode, organic light-emitting Diode) products must introduce new materials, new designs and new manufacturing processes to improve the performance of flexible and bendable OLED products. At present, an OLED display device includes a display panel and a cover window structure, and the cover window structure is arranged on one side of the display surface of the display panel to protect the display panel. However, if the cover window structure is made of a flexible material, the display panel cannot be effectively protected because of i...
