[0002] STN-LCD is a kind of display device based on liquid crystal material manufacturing.In the liquid crystal display industry, when filling LC, STN-LCD product is affected by siphon principle, the air in the box is quickly extracted under the influence of STN-LCD box and vacuum pump of filling machine, and the internal and external air pressure difference is formed, at this time, the sponge strip soaked with LC quickly injects LC into the box and flushes PI surface through STN-LCD seal, which causes the PI pre-inclination of flushing place to be flushed and reduced, causes local voltage change, and thus causes fan-shaped display unevenness at seal, which causes irreversible influence on display perception.

[0003] The size of traditional seal design is very large in order to pursue production liquid injection efficiency, usually ≥2.0mm, and the seal baffle designed for buffering and weakening liquid crystal injection potential energy is abnormally small, usually ≤1.0mm, which aggravates the generation of the above-mentioned STN-LCD display unevenness.

[0028] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model; Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments, based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the protection scope of the utility model. Embodiment

[0029] Please refer to Figure 1 - Figure 3 A STN-LCD sealing structure for improving display effect, the STN-LCD sealing structure is composed of upper sealing horn 1, lower sealing horn 2 and sealing baffle 3, the structure of upper sealing horn 1 is same with lower sealing horn 2, and the two are symmetrically distributed, the sealing baffle 3 is arranged on the same side of upper sealing horn 1 and lower sealing horn 2, LC injection upper passage 4 is formed between the side surface of upper sealing horn 1 and sealing baffle 3, LC injection lower passage 5 is formed between the side surface of lower sealing horn 2 and sealing baffle 3, and LC injection upper passage 4 and LC injection lower passage 5 are symmetrically distributed.

[0030] Please refer to Figure 1 、 Figure 2 Specifically, the gap between upper sealing horn 1 and lower sealing horn 2 is 0.8mm.

[0031] The gap between the upper sealing horn 1 and the lower sealing horn 2 in the traditional sealing structure is 2.5mm. In the improved sealing mechanism, the gap between the upper sealing horn 1 and the lower sealing horn 2 is shortened, so that the LC injection is always blocked by the sealing baffle 3, thereby buffering and weakening the injection potential energy of the liquid crystal LC.

[0032] Specifically, the length of the sealing baffle 3 is 2.2mm.

[0033] In the traditional sealing structure, the length of the sealing baffle 3 is 1.0mm. In the improved sealing mechanism, the sealing baffle 3 is lengthened by 1.2mm, and the width remains unchanged, which can block the injected LC, thereby buffering and weakening the injection potential energy of the liquid crystal LC.

[0034] Specifically, the symmetric axis of the upper sealing horn 1 and the lower sealing horn 2 is coaxial with the transverse symmetric axis of the sealing baffle 3.

[0035] By limiting the position of the sealing baffle 3, the sealing baffle 3 can effectively block the gap between the upper sealing horn 1 and the lower sealing horn 2.

[0036] Referring to Figure 1 , Figure 2 , Figure 3 Specifically, when the liquid crystal LC is injected through the LC injection upper channel 4, the liquid crystal LC forms a second bounce through the sealing baffle 3 and the upper sealing horn 1.

[0037] During the second bounce, the sealing baffle 3 and the upper sealing horn 1 both consume the injection potential energy of the liquid crystal LC. The liquid crystal LC flushes the inner wall of the sealing mechanism, forming the release of the LC injection potential energy, so that the liquid crystal LC finally slowly flows into the STN-LCD box.

[0038] Among them, Figure 3 The liquid flow No. 1 is the path when the liquid crystal LC is injected through the LC injection upper channel 4 and bounces twice.

[0039] Specifically, when the liquid crystal LC is injected through the LC injection lower channel 5, the liquid crystal LC forms a second bounce through the sealing baffle 3 and the lower sealing horn 2.

[0040] During the second bounce, the sealing baffle 3 and the lower sealing horn 2 both consume the injection potential energy of the liquid crystal LC. The liquid crystal LC flushes the inner wall of the sealing mechanism, forming the release of the LC injection potential energy, so that the liquid crystal LC finally slowly flows into the STN-LCD box.

[0041] Among them, Figure 3 The liquid flow No. 2 is the path when the liquid crystal LC is injected through the LC injection lower channel 5 and bounces twice.

[0042] Specifically, the upper sealing horn 1 and the lower sealing horn 2 are both four-segment fold line type structures.

[0043] Through the fold line type structure, the LC injection upper channel 4 and the LC injection lower channel 5 are formed, and the effective release of the injection potential of the liquid crystal LC is realized.

[0044] Working principle:

[0045] In the process of injecting the liquid crystal LC into the STN-LCD box, the liquid crystal LC passes through the gap between the upper sealing horn 1 and the lower sealing horn 2 and is blocked by the sealing baffle 3.

[0046] At this time, part of the liquid crystal LC passes through the LC injection upper channel 4, and in this process, the sealing baffle 3 and the upper sealing horn 1 consume the injection potential of the liquid crystal LC, the liquid crystal LC washes the inner wall of the sealing mechanism, the release of the LC injection potential is formed, and the liquid crystal LC finally slowly flows into the STN-LCD box.

[0047] The remaining liquid crystal LC passes through the LC injection lower channel 5, and the sealing baffle 3 and the lower sealing horn 2 consume the injection potential of the liquid crystal LC, the liquid crystal LC washes the inner wall of the sealing mechanism, the release of the LC injection potential is formed, and the liquid crystal LC finally slowly flows into the STN-LCD box.

[0048] Finally, the sealing structure reduces the potential and flow rate generated when the LC is injected into the liquid crystal box, so that it is more uniformly injected into the box and smoothly anchored in the PI groove, realizes the uniform orientation of the LC, greatly improves the uneven display abnormal phenomenon of the STN-LCD box, solves the problem of uneven display at the sealing position after the STN-LCD is filled with liquid crystal, and improves the yield of the STN-LCD product.

[0049] The above is only a preferred specific embodiment of the present application; however, the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme of the present application and the improvement concept thereof within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
