Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] The invention relates to the manufacture of TFT-LCD, in particular to the coating method of ODF (One Drop Filling, box-forming process) sealant in the manufacture of liquid crystal panels.

[0026] For negative liquid crystal products, the current method of coating frame sealant commonly used in the industry is to apply frame sealant of the same width to the four edge positions of the small panels that need to be cut from the large panel. T...

Abstract

The invention discloses a gluing method and a display panel, wherein the gluing method is used for gluing a display panel including multiple groups of sub-display panels, each group of sub-display panels includes at least two columns of sub-display panels, and for each group Sub-display panels, the glue coating method includes: coating the first colloid on the area between two adjacent columns of sub-display panels, and applying the first colloid on the outside of the left edge of the leftmost column of sub-display panels and the right edge of the rightmost column of sub-display panels. The second colloid is coated on the outside of the edge, wherein the width of the second colloid is greater than 1 / 2 times the width of the first colloid. Through the present invention, the possibility of puncturing at the edge of drip-irrigated liquid crystals during the cell-forming process of negative liquid crystal products can be effectively reduced, thereby greatly improving the yield rate of negative liquid crystal products.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a glue coating method and a display panel. Background technique [0002] At present, with the improvement of the product resolution (Pixels Per Inch, PPI for short), the wiring of the array (array) substrate on the Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) is becoming more and more complicated. density, the aperture ratio gradually decreases. In order to ensure that the visual effect of the final product is consistent with that of the low-PPI product in terms of brightness and other visual effects, it is necessary to increase the transmittance of the liquid crystal panel. Based on this, negative liquid crystal products with high transmittance have become a hot spot for development. [0003] However, in the production process of the panel (panel), the puncture of the negative liquid crystal is more serious than that of the positive liquid crystal, resultin...
