Problems solved by technology

Although in order to avoid stress-induced cracking, anisotropic thermal expansion fillers with low content are usually added when making glass frit, so in the process of making glass frit, in order to reduce the CTE of glass frit, it is necessary to extend the heat treatment time of glass frit On the one hand, it leads to energy waste, on the other hand, due to the prolongation of heat treatment time, it will lead to incomplete crystallization or insufficient filler content caused by sintering, which will eventually lead to cracks after thermal shock, which will cause glass substrates to be unsealed and reduce the product quality. yield

Abstract

The invention provides a frit composition. The frit composition comprises a frit base material and a filler, wherein the filler is an isotropic negative thermal expansion material, and the mass of the isotropic negative thermal expansion material accounts for 5-30% of the total mass of the frit composition. The frit composition can reduce the thermal expansion coefficient of frit in order to be matched with a glass substrate, can uniformly adjust the overall thermal expansion coefficient in all directions, avoids the cracks caused by the stress between the frit and the glass substrate, and improves the yield of products.

Description

technical field [0001] The invention relates to the technical field of glass frit, in particular to a glass frit composition, a glass frit paste composition and an electrical component obtained by hermetically sealing the glass paste composition. Background technique [0002] Organic layer materials exist in OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) devices, and since the organic layer materials are extremely sensitive to water vapor and oxygen, the lifetime of OLED display devices is greatly reduced. In order to solve this problem, in the prior art, various materials are mainly used to isolate the organic layer material of the OLED from the outside world. Among them, the main sealing method is to fill the sealing area of ​​the upper and lower glass substrates of the OLED display panel with glass frit, and then use the laser beam to move and heat the glass frit to melt it, thereby forming a hermetic package connection. [0003] figure 1 is a schemat...
