Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, and more specifically to a narrow-frame liquid crystal display screen. Background Art

[0002] TFT display screens not only have good display effects but also are economical, especially in consumer smart watches, smart bracelets, smart homes, electronic cigarette products and other wider applications. Due to its structure or assembly requirements, TFT display screens have a part of the border area that cannot be displayed at the edge. The existence of the border will reduce the visual effect of the entire display screen, especially the larger the border area, the worse the visual effect. Therefore, narrow borders or even borderless visual effects have become the mainstream trend of high-quality display screens. Therefore, TFT smart watch projects are now based on GIP design as the mainstream. In order to pursue a better full-screen effect, manufacturers are constantly improving the GIP design structure to make the design more in line with market demand. Utility Model Content

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

[0026] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0027] The utility model provides a narrow-frame liquid crystal display screen, which comprises a lower polarizer, a lower substrate, an upper substrate, an upper polarizer and a cover plate which are sequentially stacked from bottom to top, wherein the lower substrate is longer than the upper substrate and extends outward to form a step, and a driver IC, an FPC and a quick-check point are bound to the upper surface of the lower substrate located at the step, and the lower substrate comprises a display area, a binding area and a cutting area, wherein the binding area is arranged at the bottom side of the display area, a part of the cutting area is located at the bottom of the binding area, and another part of the cutting area is located at the top of the display area, the driver IC and the FPC are located in the binding area, and the quick-check point is located in the cutting area.

[0028] The function of the quick check point is to test the lower substrate directly through the quick check point after the lower substrate is cleaned and thinned, so as to pick out defective products and prevent the defective products of the lower substrate from being left to the next post, thereby reducing material consumption and loss. In addition, the quick check point is only used before the lower substrate is cut and will not be used again afterwards. Therefore, the quick check point is designed in the cutting area, that is, before cutting, the lower substrate is first subjected to a quick check test. If the test is normal, the lower substrate is cut. At this time, the quick check point is cut off along with the cutting post, and the quick check point part is separated along with the cutting area. In this way, the lower frame of the lower substrate will be greatly shortened. Therefore, this structural design will not affect the functional test of the lower substrate and can also greatly shorten the frame size of the lower frame of the lower substrate, thereby making the frame of the LCD screen narrower, thereby increasing the screen-to-body ratio.

[0029] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0030] See also Figure 1 and Figure 2, is a narrow-frame liquid crystal display provided by the utility model, which includes a lower polarizer 1, a lower substrate 2, an upper substrate 3, an upper polarizer 4 and a cover plate 5 which are stacked in sequence from bottom to top, the lower substrate 2 is longer than the upper substrate 3 and extends outward to form a step, the upper surface of the lower substrate 2 located at the step is bound with a driver IC 6, an FPC 7 and a quick check point 8, the lower substrate 2 includes a display area 100, a binding area 200 and a cutting area 300, the display area 100 is located in the middle part, the binding area 200 is arranged on the bottom side of the display area 100, a part of the cutting area 300 is located at the bottom of the binding area 200, and the other part of the cutting area 300 is located at the top of the display area 100, the driver IC 6 and the FPC 7 are located in the binding area 200, and the quick check point 8 is located in the cutting area 300. The function of the quick inspection point 8 is to test the lower substrate 2 directly through the quick inspection point 8 after the lower substrate 2 is cleaned and thinned, so as to pick out defective products and prevent the defective products of the lower substrate 2 from being left to the next position, thereby reducing material consumption and loss. In addition, the quick inspection point 8 is only used before the lower substrate 2 is cut and will not be used again afterwards. Therefore, the quick inspection point 8 is designed in the cutting area 300, that is, before cutting, the lower substrate 2 is first subjected to a quick inspection test. If the test is normal, the lower substrate 2 is cut. At this time, the quick inspection point 8 cuts off the cutting area 300 as the cutting position proceeds, and the quick inspection point 8 is partially separated along with the cutting area 300. In this way, the lower frame of the lower substrate 2 will be greatly shortened. Therefore, this structural design will not affect the functional test of the lower substrate 2, and can also greatly shorten the frame size of the lower frame of the lower substrate 2, thereby making the frame of the LCD screen narrower, thereby increasing the screen-to-body ratio.

[0031] Furthermore, under this structure, the distance between the edge of the binding area 200 and the bottom of the display area 100 can be as short as 3.08 mm, which greatly shortens the frame size of the lower frame of the lower substrate 2, thereby making the frame of the LCD screen narrower and increasing the screen-to-body ratio.

[0032] See also Figure 3As a further optimization scheme of Example 1, in this embodiment, an anti-fall plate 9 is arranged above the cover plate 5, and an ink layer 10 is arranged on the lower surface of the anti-fall plate 9 in the non-visible area. The cover plate 5 and the anti-fall plate 9 are fixed by an adhesive layer 11, and the adhesive layer 11 completely covers the ink layer 10 and the lower surface of the anti-fall plate 9. Since there is another layer of anti-fall plate 9 above the cover plate 5, and the adhesive layer 11 is printed on the back of the anti-fall plate 9, it covers the ink layer 10 in the non-visible area and the lower surface of the anti-fall plate 9 in the visible area, fills the ink step difference, and does not cause the phenomenon of laminating bubbles and edge yellow spots. The cover plate 5 can be fully laminated with the upper polarizer 4 through the optical glue 12. Since the cover plate 5 is not provided with an ink layer 10, it will not cause the phenomenon of laminating bubbles and edge yellow spots, thereby avoiding the display abnormality of the liquid crystal display module, thereby reducing the probability of defective products in the liquid crystal display module, and the production and manufacturing costs of the liquid crystal display module will also be greatly reduced.

[0033] And when the anti-fall plate 9 is impacted by external force, the anti-fall plate 9 will break first. Due to the buffering effect of the adhesive layer 11, the cover plate 5 is not easy to break, so the cover plate 5 and the main screen can be well protected. When the anti-fall plate 9 is broken, the anti-fall plate 9 can be easily peeled off, and only a new anti-fall plate 9 needs to be replaced. There is no need to replace the entire LCD display module, thereby greatly reducing the maintenance cost of the LCD display module, thereby improving the product competitiveness of the LCD display module, so as to meet the company's growing quality requirements.

[0034] Further, the thickness of the ink layer 10 is 8 μm to 15 μm.

[0035] Furthermore, the thickness of the adhesive layer 11 is 50 μm.

[0036] Furthermore, the thickness of the anti-fall plate 9 is 5 mm to 10 mm, and the thickness of the cover plate 5 is 3 mm to 5 mm.

[0037] Furthermore, the upper surface of the anti-fall plate 9 is covered with an anti-fingerprint film layer to prevent user fingerprints from remaining on the anti-fall plate 9 and enhance the aesthetics.

[0038] Furthermore, a color conversion layer is provided on the upper surface of the anti-fingerprint film layer located in the non-display area 100 to further enhance the aesthetics of the product.

[0039] Furthermore, the hardness of the anti-fall plate 9 is greater than the hardness of the cover plate 5 to enhance the protection effect.
