Abstract
The invention discloses an LCD manufacturing technology. Space powder to be sprayed is placed in PI liquid materials according to the required proportion of the technology, is stirred through electromagnetism to be fully even, and the mixture is naturally and evenly coated on faces of an LCD product through the PI coating technology and is evenly distributed in the product through PI curing. The LCD manufacturing technology lowers the production cost and improves product quality.
Description
Technical field
The present invention relates to LCD production field, be specifically related to a kind of LCD liquid crystal display manufacture craft.
Background technology
Spraying spacer particle is an indispensable procedure in traditional LC D liquid crystal display manufacture craft, and shower nozzle uninterruptedly sprays facing to streamline, and arrange air exhauster simultaneously and take unnecessary particle away, this just causes the waste of particle, improves production cost.
Spray spacer particle, sprinkling can be caused uneven, cause the bad phenomenon such as rainbow between box, display inequality and short circuit.
Summary of the invention
The object of the invention is to: provide a kind of and improve spacer particle utilization factor, improve the LCD liquid crystal display manufacture craft of product yield simultaneously.
Be achieved through the following technical solutions: a kind of LCD liquid crystal display manufacture craft, comprises the steps:
(1) feed intake;
(2) cleaning before PR;
(3) PR coating;
(4) expose;
(5) develop;
(6) post bake;
(7) etch;
(8) demoulding;
(9) cleaning before PI;
(10) the PI liquid that Homogeneous phase mixing has spacer particle is coated with;
(11) PI is roasting solid;
(12) rub;
(13) frame, print point is drawn;
(14) combine;
(15) pressure is roasting.
Compared with prior art, the present invention has following beneficial effect:
One, manufacture craft of the present invention, does not spray the operation that unnecessary particle taken away by particle and air exhauster, decreases the waste of spacer particle, promote the utilization rate of particle, reduce production cost.
Two, manufacture craft of the present invention, spacer particle is blended in PI liquid, not only reduces one production process, meanwhile, greatly reduces the appearance of the bad phenomenon such as particle is uneven, improves the quality of product.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention.
Embodiment
Manufacture craft of the present invention, spacer particle is added in PI liquid when PI material prepares, pass through electromagnetic agitation, make it full and uniform, coating ITO electrode surface in box together with PI, directly to support box thick, be cured after directly operation below being needed the spacer particle sprayed to add in PI liquid together coating, be more directly combined into right after printing frame adhesive and firing point, eliminate spraying spacer particle operation below.Namely improve production efficiency reduce simultaneously spray operation take out of in the fabrication process bad, ensure that the quality of product, spacer particle is added in PI liquid and be coated with when reducing product-free when former operation sprays also at the spacer particle sprayed and exhausting is drained, control the use amount of spacer particle, decrease the waste of spacer particle, can save material.
