5results about How to "Reduce bend radius" patented technology

The invention provides a display panel and a preparation method thereof and a display device.The display panel is provided with a display area and a non-display area at least partially surrounding the display area, the non-display area comprises a first non-display sub-area and a bending area which are located on at least one side of the display area, and the bending area is located on the side, away from the display area, of the first non-display sub-area. The display panel includes a substrate extending from a display area to a bending area; the conducting layer is located on one side of the substrate, and at least part of the conducting layer is located in the bending area; at least part of the adjusting layer is located in the bending area, and the adjusting layer is located between the substrate and the conductive layer; the first film layer is located on the side, away from the substrate, of the conducting layer, and at least part of the first film layer is located in the bending area; the thickness of the substrate in the bending area is smaller than that of the substrate in the display area and / or the first sub-non-display area. According to the technical scheme, the extremely small bending radius can be achieved.

This invention belongs to the field of cable technology, specifically a thin-walled oxygen-barrier high-temperature resistant cable, comprising a conductor core and a thin-walled outer sheath. The conductor core has a high-temperature resistant insulation layer made of polyetheretherketone (PEEK) composite material on its outer side. Between the high-temperature resistant insulation layer and the thin-walled outer sheath, from the inside out, are sequentially arranged a ceramicized oxygen barrier layer and a flame-retardant reinforcement layer. The ceramicized oxygen barrier layer is a nano-modified ceramicized silicone rubber layer with a thickness of 0.05–0.15 mm, including an outer layer doped with silicon carbide whiskers and an inner layer doped with zinc borate. This invention prepares an ultra-thin ceramicized layer through gradient doping, resolving the contradiction between thin-walled design and oxygen barrier properties, and effectively improving the interfacial peel strength. This reduces the cable's outer diameter and bending radius, making the cable lightweight and suitable for high-dynamic applications.

The application provides a display panel and a display device. The display panel has a display area, a bending area and a binding area. The bending area is located between the display area and the binding area. The display panel comprises a display substrate and a touch protection layer. The touch protection layer is arranged on the light-emitting side of the display substrate. The touch protection layer extends from the display area to the binding area through the bending area. The display panel provided by the application enables the touch protection layer to cover the part of the display substrate located in the bending area. The touch protection layer can replace the film layer of the part of the display substrate located in the bending area. The touch protection layer can effectively disperse stress during the bending process of the display panel, thereby improving the bending performance. Meanwhile, the overall laminated layer and thickness of the bending area can be thinned, which is conducive to the design of products with smaller bending radius and can also reduce the material cost.

The invention discloses a digital media display device with cleaning and dustproof functions, and belongs to the technical field of digital media display. A digital media display device with cleaning and dustproof functions is characterized in that the digital media display device comprises a winding device arranged in a storage box, and the winding device is provided with a rotary storage sleeve used for winding a flexible screen; the lifting device is arranged in the storage box, and the top of the rolling flexible screen is connected with the top of the lifting device; the cleaning device is arranged on the rotary storage sleeve in a sleeving manner; and the driving mechanism is used for driving the cleaning device to move to clean the flexible screen wound on the rotary storage sleeve. The problems that in a traditional digital media display device, dust is exposed and accumulated in the non-display period of the screen in the daytime, and the attractiveness and the display effect are affected by using a dustproof cover are effectively solved.

The invention provides a glass etching solution, a glass cover plate, a preparation method of the glass cover plate, a flexible display screen and electronic equipment. The glass etching liquid provided by the embodiment of the invention comprises the following components in percentage by mass: 30-50% of hydrofluoric acid; 10% to 30% of sulfuric acid; 5% to 20% of nitric acid; and 2% to 8% of oxalic acid. When the glass etching liquid provided by the embodiment of the invention is used for thinning and etching the glass substrate, the surface of the etched glass substrate is free of crystal points, flow mark lines and heterochromatic points, and the surface of the thinned glass substrate has better smoothness and lower roughness, so that the glass substrate has higher light transmittance and appearance effect.
