Embodiment Construction

[0020] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The superficial terms mentioned in the present invention, such as [upper], [lower], [front], [back], [left], [right], [inner], [outer], [side], etc., are only for reference Attach the surface of the schema. Therefore, the superficial terms used are for explaining and understanding the present invention, but not for limiting the present invention. In the figures, elements with similar structures are denoted by the same reference numerals.

[0021] The invention provides a frame-sealing glue material and a liquid crystal display panel, so as to alleviate the technical problem that the existing frame-sealing glue has insufficient ability to isolate water vapor under high-temperature and high-humidity conditions.

[0022] In liquid crystal displays, the sealant is mainly used to seal the upper and lower substr...

Abstract

The invention provides a frame sealing adhesive material and a liquid crystal display panel. The frame sealing adhesive material comprises the following components in percentage by mass: 25%-50% of anepoxy resin prepolymer, 5%-25% of an acrylic resin prepolymer, 0.1%-12% of a curing agent, 0-3% of a curing accelerator, 3%-20% of a filler, 0-3% of a stabilizer, 0-3% of an additive and 1-15% of a nano inorganic substance. The nano inorganic substance is added into the prepolymer and is uniformly dispersed in the prepolymer system, so that a water vapor permeation path can be prolonged after thenano inorganic substance is cured, and the water vapor barrier capacity of the frame sealing adhesive under high-temperature and high-humidity conditions is effectively improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a frame sealant and a liquid crystal display panel. Background technique [0002] In liquid crystal displays, the sealant is mainly used to seal the upper and lower substrates of the liquid crystal cell to prevent water vapor from entering and at the same time support the gap between the upper and lower plates to maintain a stable and reliable environment inside the box. Therefore, the water vapor barrier properties of the sealant material play a decisive role in the liquid crystal display. The current sealing material can still meet the requirements of product reliability under normal temperature and humidity conditions, but its performance needs to be further improved under more stringent high temperature and high humidity conditions. [0003] Therefore, the existing frame sealant has the technical problem of insufficient ability to isolate water vapor under high-temperature a...
