Problems solved by technology

Although most of the anti-fingerprint coatings on the market can form chemical bonds with metal, glass and other material substrates by dehydration condensation of hydroxyl groups to produce a certain bonding force, they cannot be combined with cured hydrophilic resin layers, such as epoxy resins. Resin glue forms an effective chemical combination, so the bonding force between the nano-coating and the hydrophilic resin layer is extremely poor, and the nano-coating is easy to detach from the rubber surface under the action of external force, which cannot achieve a stable anti-fingerprint effect
In addition, the existing nano-coatings have poor hydrophobic effect, and the best hydrophobic effect of the currently used fluorine-containing nano-coatings is only around 110°-120°

Abstract

An LED display screen and a preparation method thereof, the LED display screen has a lamp surface, a hydrophilic resin protective layer and a transparent modified polysilazane resin layer are sequentially arranged on the lamp surface, and the hydrophilic resin protective layer is located on the Between the lamp surface and the transparent modified polysilazane resin layer; wherein, the material of the transparent modified polysilazane resin layer includes the following components: polysilazane resin, silane coupling agent and Gas-phase hydrophobic nano-silica particles. The above-mentioned LED display screen can have a better anti-fingerprint effect by providing a transparent modified polysilazane resin layer on the hydrophilic resin protective layer. Due to the use of polysilazane resin, it can improve the bonding force between the gas-phase hydrophobic nano-silica particles and the protective layer of the hydrophilic resin, thereby making the nano-coating of the transparent modified polysilazane resin layer and the rubber surface of the hydrophilic resin layer The binding force is strong, which can achieve a relatively stable anti-fingerprint effect, and the hydrophobic effect is good.

Description

technical field [0001] The present application relates to the technical field of display screens, in particular to an LED display screen and a preparation method thereof. Background technique [0002] With the growing market size of indoor small-pitch LED displays in recent years, the stability and reliability of large-screen LED display products has become one of the research hotspots in the LED display industry. Aiming at how to improve the stability of the light surface of the small-pitch LED display, a popular solution at present is to use transparent epoxy resin glue to pour glue on the surface of the LED module to improve the anti-dropping of the light surface of the small-pitch LED display. Light, anti-collision, anti-scratch, waterproof and dustproof, and a series of protective properties, which in turn protect the surface of the lamp and the LED module. However, the rubber surface potted on the surface of the LED module is easily contaminated with fingerprints, dus...
