Description
Technical Field
The present invention relates to a liquid crystal display panel technology, and more particularly, to a liquid crystal display panel.
Background
For the LCD (Liquid Crystal Display) panel, the panel is required to be more and more thin, and therefore the thinning process is required after the panel is produced. At present, the common practice is to soak the surface of the glass panel with acid solution and then polish the surface.
When the LCD panel is thinned, large glass of a large generation line is cut into a plurality of small Block-shaped glass, a circle of Block Seal is coated on the periphery of the glass in a mode of coating the periphery of the glass by a circle of frame glue, then a circle of waterproof glue is coated on the periphery of the Block Seal, and under the protection of two circles of glue, the glass is prevented from being corroded by acid liquor during thinning.
In the actual process of manufacturing the LCD panel, the two layers of glass are tightly attached together in a mode that the vacuum breaking is completed in the Block Seal coating process to ensure that the pressure of the outer layer of the glass is greater than the pressure of the inner part of the glass. However, when the actual Block Seal is coated, due to the fact that the width precision of the region glue corresponding to the Block Seal corner is poor, glue breaking or too thin glue frame width is easy to occur, and due to the fact that the pressure difference inside the glass is too large at the moment of vacuum breaking, the glue frame is easy to break at the corner regions, and large-area breakage occurs. When the glass is thinned, external acid liquid easily enters from the broken area of the glue, so that the metal circuit is corroded. Meanwhile, the glass is easy to deform due to overlarge pressure difference inside the glass, so that the thickness of the box is uneven, and normal display is influenced.
