Method for manufacturing drilling display panel and silk screen board

Abstract

The invention discloses a method for manufacturing a drilling display panel. The method comprises the steps of providing an array substrate and a color film substrate; providing a first silk screen board and a second silk screen board; utilizing the first silk screen board to obtain a first drilling area sealant, and utilizing the second silk screen board to obtain a frame area sealant and a second drilling area sealant; oppositely sticking the array substrate and the color film substrate and performing hot-press curing to obtain a semi-finished product; and performing drilling to obtain the drilling display panel; wherein the sealant leaking amount of the first drilling area sealant or the second drilling area sealant accounts for 50-55% of the total of the drilling area sealants. The invention further discloses a silk screen board. The total of the drilling area sealants is distributed on the two substrates, the problem that when a silk screen is one substrate surface, since the diameter of the sealant is large, the top forms a spherical concave surface, gas in the concave surface is heated and expands and breaks through the sealant is solved, and thus the shortcomings that liquid crystal leaks easily after drilling and stress in the drilling process leads to breakage and separation of the array substrate and the color film substrate are overcome.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a drilled display panel and a screen printing screen. Background technique [0002] With the rise of smart wearable products, smart watches with physical pointer displays and vehicle-mounted liquid crystal displays combine traditional watches with high-tech smart displays to stimulate customers' consumption desires. However, for displays with physical pointers, it is necessary to drill holes in the display panel to obtain through holes to install pointers, and the periphery of the through holes in the drilled area is to prevent liquid crystal leakage and force TFT array substrates and color filter substrates to be broken and separated during the drilling process. The sealing ring located on the periphery of the through-hole must be solid, complete and reliable. However, in the actual process, the sealant in the drilled area obtained by silk screen prin...

Problems solved by technology

However, for displays with physical pointers, it is necessary to drill holes in the display panel to obtain through holes to install pointers, and the periphery of the through holes in the drilled area is to prevent liquid crystal leakage and force TFT array substrates and color filter substrates to be broken and separated during the drilling process. The sealing ring located on the periphery of the through-hole must be solid, complete and reliable. However, in the actual process, the sealant in the drilled area obtained by silk screen printing according to the existing process cannot be completely and reliably sealed due to the presence of bubbles in the sealant in the drilled area after curing. Finally, there are defects that the liquid crystal is easy to leak, and the array substrate and the color filter substrate are cracked and separated due to the force during the drilling process.
