Substrate, liquid crystal display panel and manufacturing method of substrate

Abstract

The invention provides a substrate, a liquid crystal display panel and a manufacturing method of the substrate. The manufacturing method of the substrate comprises the steps of paving an alkali ion shielding layer on substrate glass and preparing a substrate function layer on the alkali ion shielding layer. By paving the alkali ion shielding layer on the substrate glass, the purpose of taking chemical tempered glass as the substrate glass is realized, thereby enhancing the strength of the substrate and the liquid crystal display panel; the liquid crystal display panel manufactured by the substrate can be used independently without extra protective covering articles, so that the properties of collision resistance, scratch resistance and maintenance easiness of the liquid crystal display panel are improved, the number of protective layers is reduced, light loss is reduced, and the original color of the liquid crystal display panel is recovered.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to a substrate, a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] With the development of modern technology, electronic display products have developed rapidly in recent years, and advanced flat panel display products emerge in endlessly, ranging from small to large in size, ranging from mobile phones and PDA products to large TVs and print advertising media machines. Flat-panel display products include plasma TVs, LCD TVs, notebooks, cash machines, mobile phones, PDAs, PSPs, information inquiry machines, media advertising players, etc. Therefore, the demand for flat-panel display panels for flat-panel display products is also increasing. Display panels include liquid crystal display panels (LCDs), plasma display panels (PDPs), and organic light-emitting diodes (OLEDs), among which LCDs are widely used in mass production pro...

Problems solved by technology

However, chemically tempered glass is prone to stress relaxation over time.

[0006] In the face of the increasingly ultra-thin requirements of flat display panels, in order to save the protection of the flat display panel by the transparent cover, when using chemically tempered glass for the production of ultra-thin flat display panels, due to the high alkali content on the surface of the chemically tempered glass , will damage the life of the panel; moreover, the large production lines of flat panel display panels directly make multiple display panels on a large glass plate, and then cut them to obtain multiple single display panels. However, when chemically tempered glass is actually used, In order to prevent stress release and loss of strength at the edge after cutting, the treatment process of chemical toughening after cutting is often used, which conflicts with the production line of flat display panels. Therefore, in the prior art, chemically tempered glass is still more used as flat Display panel protective cover glass for use

[0007] However, due to the use of chemically tempered glass as a transparent cover, although the strength of the flat display panel is increased, when the applied pressure increases, the flat display panel may break before the chemically tempered glass breaks, and the additional chemically tempered glass It will also greatly increase the thickness and weight of the flat display panel, and the production cost will be higher
