A lubricating oil friction modifier and a preparation method therefor and use thereof are provided. The lubricating oil friction modifier has a chemical formula of AB(C). In the formula, A is a perfluoropolyether acyl group, Brepresents a cationic group having x amino groups and y ammonium ions, Cis BF, PF, AsF, FAP, TFSI, MnOor ClO, x is an integer greater than or equal to 1, y is an integer greater than or equal to 1, and x+y≥2. The lubricating oil friction modifier has a good solubility with fluorine oil and fluorine grease, will not precipitate in the fluorine oil and the fluorine grease after being added, and can significantly improve the wear resistance of a lubricating oil such as the fluorine oil and the fluorine grease.

Lubricating oil friction modifier and preparation method therefor and application thereof

A display substrate is provided. The display substrate includes a plurality of organic material film layers and a plurality of inorganic material film layers, wherein the plurality of organic material film layers and the plurality of inorganic material film layers are provided with a functional hole, and the functional hole is disposed in an aperture area of the display substrate. An organic material is provided on an inner side wall of the functional hole in at least one of the inorganic material film layers.

Display substrate, display device and method of manufacturing same

A display substrate includes: a base substrate; a first driving signal line arranged at a camera-free region; a second driving signal line arranged at an under-screen camera region, a light transmittance of the first driving signal line being smaller than a light transmittance of the second driving signal line, and the second driving signal line including at least two layers of leads; and a touch structure arranged on the base substrate and arranged at at least one of the camera-free region and the under-screen camera region. The touch structure includes at least two layers of touch signal lines, one layer of touch signal lines is made of a same material and arranged at a same layer as one layer of leads, and the other layer of touch signal lines is made of a same material and arranged at a same layer as the other layer of leads.
