Background
In recent years, the development of flat panel display technologies FPDs such as LCD liquid crystal display, OLED organic electroluminescent display, PDP plasma display, and FED field electron emission display is rapid, replacing the conventional CRT cathode ray tube display technology, and becoming the mainstream display device of the present civil electronic products. However, these conventional display devices are often limited to planar use, have high power consumption, are bulky and heavy, and have not been able to satisfy the requirements of low power consumption and portability of portable products. The size, weight and power consumption requirements are greatly reduced, and the research on flexible substrate-based displays and related technologies becomes a new topic in the research field of display devices.
A flexible display screen is an FPD (flat panel display) with a light and thin substrate made of flexible materials, and the flexible display screen can not influence the display function of the display device due to deformation such as bending and curling given by the outside, so the flexible display screen is not limited to planar engineering application any more. The related technology is mainly developed by the following links of firstly selecting a substrate of a flexible substrate, then selecting a display material and preparing the display screen, and finally designing a corresponding drive control circuit. The OLED and the EPD belong to active light-emitting devices according to a device pixel light-emitting mechanism, while LCD liquid crystal molecules cannot emit light, only under the action of an external electric field, the transmission path of incident light is changed due to the change of molecular arrangement, and the display device is a light-receiving display device and realizes the display by influencing the transmission direction of an environmental light source.
CN 107180599A discloses a display screen, including flexible screen, hard screen and flexible circuit board, the flexible screen has the fretwork region, and hard screen sets up in the fretwork region, and the signal binding on the hard screen is on the flexible circuit board, and the signal binding on the flexible circuit board is on the flexible screen. According to the display screen provided by the invention, the hard screen is arranged in the hollow area of the flexible screen, and the flexible screen and the hard screen are spliced together to form the display screen, so that the display screen can be bent, the part for arranging the hard screen improves certain rigidity for the display screen, the display screen is conveniently applied to various devices, various components such as a fingerprint identification module are conveniently pasted, and the reliability of the display screen is improved.
CN 108155218A discloses a flexible display screen, comprising: a plurality of functional film layers which are sequentially superposed; at least one layer of the multi-layer functional film layer comprises a plurality of sections of module materials respectively, a gap or a groove is arranged between two adjacent sections of module materials, and elastic materials are filled in the gap or the groove. The grooves or the gaps can reduce the contact area between the functional film layers where the module materials are located and the adjacent functional film layers, so that when the flexible display screen is bent, the bending stress of the functional layer where the module materials are located on the adjacent functional film layers is reduced, and the adjacent functional film layers are prevented from being separated or broken. Furthermore, elastic materials are filled in the gaps or the grooves, so that stress concentration of the functional film layer where the gaps or the grooves are located can be relieved when the flexible display screen is bent, and bending stress is released.
