Embodiment Construction

[0027] When the sealant is cured, the sealant is firstly cured by ultraviolet light, and then heat-cured. Due to the shielding of the metal wire, the sealant after pre-curing by ultraviolet light is prone to problems such as uneven and incomplete curing. When the mobile display panel is thermally cured, the pre-cured incomplete sealant is easy to contact with the liquid crystal, causing problems such as liquid crystal contamination and puncture.

[0028] Embodiments of the present invention provide a display panel and a display device. The display panel includes a first substrate and a second substrate oppositely arranged, and a sealant structure for bonding the first substrate and the second substrate. In the technical solution of the present invention, through the sealant structure A conversion unit is provided to convert the infrared light (IR) irradiated on the conversion unit when curing the sealant into ultraviolet light (UV), so that both infrared light can be used to r...

Abstract

The invention provides a display panel and a display device. The display panel comprises a first base board and a second base board which are arranged oppositely and a sealing frame glue structure used for bonding the first base board with the second base board, wherein the sealing frame glue structure comprises sealing frame glue and a converting unit, and the converting unit is used for converting infrared light irradiated when the sealing frame glue is cured into ultraviolet light. According to the display panel, through the arrangement of the converting unit in the sealing frame glue structure, light curing and heat curing are achieved through single-step technology, and problems that when the ultraviolet light curing and the heat curing are separately performed on the sealing frame glue, since the pre-curing is incomplete, the sealing frame glue is prone to making contact with liquid crystals, and the pollution and the impalement of the liquid crystals occur are avoided.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] The liquid crystal display panel is composed of an array substrate 1 and a color filter substrate 2, such as figure 1 As shown, a sealed space is formed by bonding the array substrate 1 and the color filter substrate 2 with the sealant 5 , and the liquid crystal is filled in the sealed space, and the display is realized by controlling the liquid crystal molecules in the display area 3 . Wherein, the curing of the frame sealing glue 5 is a very important process step in the liquid crystal display panel-to-cell process. [0003] At present, the curing process of the frame sealant is mainly divided into two steps: first, the liquid crystal display panel is irradiated with ultraviolet light (UV) for pre-curing, and then transferred to a heating furnace for high-temperature thermal curing, so as to realize the sealing of ...
