Technical Field
[0001] The utility model relates to the technical field of liquid crystal display, and more specifically, to a liquid crystal display screen for preventing electrostatic injury to quick inspection points. Background Art
[0002] TFT display screens not only have good display effects but also are economical in price, and are especially widely applied in consumer smart watches, smart bracelets, smart home appliances, electronic cigarette products, etc. The projects of TFT smart watches are now mainly based on the GIP design. In order to further narrow the width of the lower border of the TFT, the TFT quick inspection points are made outside the lower substrate and are cut off together with the cut glass after the detection, so as to narrow the width of the lower border.
[0003] As this part of the glass is cut off together with the quick inspection points, the connection lines of the quick inspection points will still remain on the edge of the glass cutting. When encountering static electricity, the static electricity will hit the edge of the TFT glass, and this position happens to be the wiring position of the TFT quick inspection points. The static electricity will discharge along this end, thus injuring the TFT glass and resulting in the problem of poor antistatic ability. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is how to prevent the liquid crystal display screen from being damaged when the quick inspection points are hit by static electricity.
[0005] The technical problem to be solved by the utility model is realized through the following technical solutions:
[0006] To solve the above technical problem, the utility model provides a liquid crystal display screen for preventing electrostatic injury to quick inspection points, which includes a lower polarizer, a lower substrate, an upper substrate, and an upper polarizer that are sequentially stacked from bottom to top. The lower substrate is longer than the upper substrate and extends outwards to form a step. A driving IC, an FPC, and a plurality of quick inspection point remaining lines are arranged on the upper surface of the lower substrate at the step. A laser cutting line is arranged on the upper surface of the lower substrate, and the laser cutting line cuts off all the plurality of quick inspection point remaining lines.
[0007] As a preferred implementation manner of the liquid crystal display screen for preventing electrostatic injury to quick inspection points provided by the utility model, a plurality of quick inspection point remaining lines are distributed on both sides of the driving IC. There are two laser cutting lines, and the positions of the two laser cutting lines correspond to the positions of the quick inspection point remaining lines on both sides of the driving IC.
[0008] As a preferred implementation manner of the liquid crystal display screen for preventing electrostatic injury to quick inspection points provided by the utility model, there are 14 quick inspection point remaining lines and they are evenly distributed on both sides of the driving IC.
[0009] As a preferred embodiment of the liquid crystal display provided by the present utility model for preventing static electricity from injuring the quick inspection points, there are multiple laser cutting lines arranged in parallel with each other.

[0016] The present utility model has the following beneficial effects:
[0017] When glass cutting is performed, the laser cutting lines are cut out together, thus avoiding cost increase.

Doing so can prevent static electricity from damaging the liquid crystal display through the quick inspection point remaining lines without increasing cost, and improves the competitiveness of the product.

[0027] In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", "third" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0028] The utility model provides a liquid crystal display screen for preventing static electricity from injuring quick inspection points, which comprises a lower polarizer, a lower substrate, an upper substrate and an upper polarizer that are sequentially stacked from bottom to top. The lower substrate is longer than the upper substrate and extends outwards to form a step.

A laser cutting line is arranged on the upper surface of the lower substrate, and the laser cutting line completely cuts off the plurality of quick inspection point remaining lines.
[0029] When glass cutting is carried out, the laser cutting line is cut out together, so as to avoid increasing the cost. And since the laser cutting line completely cuts off the plurality of quick inspection point remaining lines, even if static electricity enters from the quick inspection point remaining lines and reaches the broken line, it will not continue to conduct to the internal wiring of the liquid crystal display screen. Doing so can not only avoid increasing the cost but also effectively prevent static electricity from damaging the liquid crystal display screen through the quick inspection point remaining lines, thus improving the competitiveness of the product.
[0030] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the drawings. The present utility model will be described in detail below with reference to the drawings and embodiments. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.
[0031] Please refer to Figures 1 to 4 Figure, which is a liquid crystal display screen for preventing static electricity from injuring quick inspection points provided by the present utility model. It comprises a lower polarizer, a lower substrate 1, an upper substrate 2 and an upper polarizer that are sequentially stacked from bottom to top. The lower substrate 1 is longer than the upper substrate 2 and extends outwards to form a step. A driving IC 3, an FPC 4 and a plurality of quick inspection point remaining lines 5 are arranged on the upper surface of the lower substrate 1 at the step. A laser cutting line 6 is arranged on the upper surface of the lower substrate 1, and the laser cutting line 6 completely cuts off the plurality of quick inspection point remaining lines 5. When glass cutting is carried out on the cutting area 100, the laser cutting line 6 is cut out together, so as to avoid increasing the cost. And since the laser cutting line 6 completely cuts off the plurality of quick inspection point remaining lines 5, even if static electricity enters from the quick inspection point remaining lines 5 and reaches the broken line, it will not continue to conduct to the internal wiring of the liquid crystal display screen. Doing so can not only avoid increasing the cost but also effectively prevent static electricity from damaging the liquid crystal display screen through the quick inspection point remaining lines 5, thus improving the competitiveness of the product.
[0032] Further, multiple quick inspection point legacy lines 5 are distributed on both sides of the driving IC 3. There are two laser cutting lines 6, and the positions of the two laser cutting lines 6 correspond to the positions of the quick inspection point legacy lines 5 on both sides of the driving IC 3. In this embodiment, there are 14 quick inspection point legacy lines 5 and they are evenly distributed on both sides of the driving IC 3.
[0033] Further, there are multiple laser cutting lines 6 and they are arranged in parallel with each other. In this embodiment, there are 5 laser cutting lines 6 to ensure that the laser cutting lines 6 can cut off the quick inspection point legacy lines 5, avoiding the situation where some of the quick inspection point legacy lines 5 are about to break but not completely broken during cutting, further ensuring that static electricity cannot enter the liquid crystal display screen through the quick inspection point legacy lines 5, improving the antistatic ability of the product, and thus enhancing the competitiveness of the product.
[0034] Please refer to Figures 1 to 4 , as a further optimized solution of Embodiment 1, in this embodiment, the laser cutting line 6 forms a cutting groove, that is, the cutting width of the laser cutting line 6 is increased to form a cutting groove shape, so as to avoid the situation of being about to break but not completely broken and improve the antistatic ability.
[0035] Further, the width of the laser cutting line 6 is 0.1 mm.
[0036] Further, the laser cutting line 6 does not penetrate to the lower surface of the lower substrate 1, that is, the laser cutting line 6 does not penetrate the lower substrate 1. Preferably, the depth of the laser cutting line 6 is 1 mm deeper than the depth of the quick inspection point legacy line 5.
[0037] Further, a wire is arranged on the quick inspection point legacy line 5 inside the laser cutting line 6. The wire is electrically connected to the FPC 4 and grounded, so that even if static electricity strikes the quick inspection point legacy line 5 inside the laser cutting line 6, the static electricity can still be guided to the grounding point of the FPC 4 through the wire, thereby discharging the static electricity and avoiding the breakdown of the static electricity accumulation into the liquid crystal display screen. In this embodiment, the wire is conductive silver paste.
