Background
Folding screen refers to flexible OLED. The production of the folding screen is not only greatly beneficial to the manufacture of new generation high-end smart phones, but also has profound effects on the application of wearable equipment due to the low power consumption and the flexible characteristic of the folding screen, and the folding screen is widely applied along with the continuous penetration of personal intelligent terminals in the future. Folding screen handsets are those that employ a flexible, flexible screen because they resemble a scroll, also known as a scroll handset. Compared with the traditional screen, the folding screen has obvious advantages, is lighter in size and lighter in power consumption, is lower than the original device, is favorable for improving the endurance capacity of equipment, and is also higher than the traditional screen greatly in durability based on the characteristics of being bendable and good in flexibility, so that the probability of accidental damage of the equipment is reduced.
In order to realize the folding function of the folding screen, besides the screen, the design of a connecting shaft of a folding connecting assembly, namely a bending part, is also the biggest technical problem. Considering the specificity of folding screen, traditional pivot has not had the method to satisfy its functional requirement, needs special folding screen pivot to assist the realization, and considering to use with flexible screen, flexible screen has its specificity, and the industrialization processing of pivot itself also has certain degree of difficulty, and the precision requirement of its accessory is extremely high, how to satisfy flexible screen application while simplifying the processing degree of difficulty, just can realize industrialization.
In the bending and rotating process of the flexible screen, how to ensure auxiliary synchronization and meet the precision requirement, especially abnormal noise cannot be generated, enough reserved space is needed, the service life stability is required to be met, and the design of the synchronous rotating mechanism is one of key technical elements.
