Description

Technical Field

[0001] This utility model relates to the field of display technology, and more specifically, to a waterdrop screen that improves the effectiveness of rapid detection data. Background Technology

[0002] In the display panel industry, the fast test circuit of the array is generally located on both sides of the bottom of the screen, occupying a large area of ​​traces. Furthermore, the test leads are pulled out from the bottom, which differs from the actual display configuration. The fast test leads are pulled directly from the fanout trace area between the driver IC and the bottom of the array (AA). In this case, only the potential between the driver IC's output signal and the fanout area can be tested; the potential at the top of the display area cannot be actually tested. The measured potential is almost equal to the potential provided by the driver IC, making the measurement data unreliable. Utility Model Content

[0003] The technical problem to be solved by this invention is how to improve the data validity of fast detection circuits.

[0004] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0005] To address the aforementioned technical problems, this utility model provides a waterdrop screen that improves the effectiveness of rapid detection data. The screen includes a lower substrate, comprising a display area, a bonding area, and a waterdrop area. The display area is located in the middle, the bonding area is located at the bottom of the display area, and the waterdrop area is located at the top of the display area. A driver IC is bonded to the bonding area, and a rapid detection PAD is disposed in the waterdrop area. Multiple source lines are disposed on the upper surface of the lower substrate. One end of each source line is bonded to the driver IC, and the other end of each source line passes through the display area and is bonded to the rapid detection PAD.

[0006] As a preferred embodiment of the waterdrop screen for improving the effectiveness of rapid detection data provided by this utility model, an FPC is bonded to the upper surface of the lower substrate located at the bottom of the driver IC.

[0007] As a preferred embodiment of the waterdrop screen for improving the effectiveness of rapid testing data provided by this utility model, a traceability label is provided on the surface of the FPC.

[0008] As a preferred embodiment of the waterdrop screen for improving the effectiveness of rapid testing data provided by this utility model, a shielding paper is provided on the surface of the FPC, and the shielding paper covers the surface of the FPC and the traceability label paper.

[0009] As a preferred embodiment of the waterdrop screen for improving the effectiveness of rapid testing data provided by this utility model, the shielding paper includes a shielding layer, an adhesive layer and a non-adhesive layer stacked sequentially from top to bottom. The size and position of the non-adhesive layer correspond to the size and position of the traceability label paper. The non-adhesive layer covers the traceability label paper, and the adhesive layer covers the surface of the FPC.

[0010] In a preferred embodiment of the waterdrop screen for improving the effectiveness of rapid detection data provided by this utility model, the thickness of the non-adhesive layer is 0.03mm-0.06mm.

[0011] As a preferred embodiment of the waterdrop screen for improving the effectiveness of rapid testing data provided by this utility model, the edge of the non-adhesive layer extends 1.5mm to 3mm beyond the edge of the traceability label paper.

[0012] As a preferred embodiment of the waterdrop screen for improving the effectiveness of rapid detection data provided by this utility model, the non-adhesive layer and the shielding layer have different appearance colors.

[0013] In a preferred embodiment of the waterdrop screen for improving the effectiveness of rapid detection data provided by this utility model, the non-adhesive layer is white and the shielding layer is black.

[0014] In a preferred embodiment of the waterdrop screen for improving the effectiveness of rapid testing data provided by this utility model, the cross-sectional area of ​​the shielding paper is larger than the cross-sectional area of ​​the traceability label paper.

[0015] This utility model has the following beneficial effects:

[0016] Due to series voltage division, the resistance varies at different source line segments from the driver IC to the top of the display area. Furthermore, numerous coupling capacitors are generated at the top of the display area, all contributing to voltage division and causing different potentials at different locations on the source line. This means that traditional position measurements fail to measure the losses caused by voltage division, resulting in low validity of the fast test data. Since the fast test PAD is located on the waterdrop area at the top of the display area, meaning the fast test line extends from this area, it can measure the potential of the driver IC output signal after it reaches the fanout area and passes through the display area. This allows for a complete test of the actual displayed potential, improving the validity of the fast test data. Moreover, since the waterdrop area typically has no traces, it does not affect the waterdrop area's traces. Moving the fast test PAD from the bonding area to the waterdrop area reduces the occupied area, freeing up space in the bonding area. Attached Figure Description

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] This utility model provides a waterdrop screen to improve the effectiveness of rapid detection data. It includes a lower substrate, which includes a display area, a bonding area, and a waterdrop area. The display area is located in the middle, the bonding area is located at the bottom of the display area, and the waterdrop area is located at the top of the display area. A driver IC is bonded to the bonding area, and a rapid detection PAD is disposed in the waterdrop area. Multiple source lines are disposed on the upper surface of the lower substrate. One end of each source line is bonded to the driver IC, and the other end of each source line passes through the display area and is bonded to the rapid detection PAD.

[0030] Due to series voltage division, the resistance varies at different source line segments from the driver IC to the top of the display area. Furthermore, numerous coupling capacitors are generated at the top of the display area, all contributing to voltage division and causing different potentials at different locations on the source line. This means that traditional position measurements fail to measure the losses caused by voltage division, resulting in low validity of the fast test data. Since the fast test PAD is located on the waterdrop area at the top of the display area, meaning the fast test line extends from this area, it can measure the potential of the driver IC output signal after it reaches the fanout area and passes through the display area. This allows for a complete test of the actual displayed potential, improving the validity of the fast test data. Moreover, since the waterdrop area typically has no traces, it does not affect the waterdrop area's traces. Moving the fast test PAD from the bonding area to the waterdrop area reduces the occupied area, freeing up space in the bonding area.

[0031] 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 with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which 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 throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] Example 1, please refer to Figure 1 This invention provides a waterdrop screen for improving the effectiveness of rapid detection data. It includes a lower substrate 1, which comprises a display area 11, a bonding area 12, and a waterdrop area 13. The display area 11 is located in the middle, the bonding area 12 is located at the bottom of the display area 11, and the waterdrop area 13 is located at the top of the display area 11. A driver IC 2 is bonded to the bonding area 12, and a rapid detection PAD 3 is disposed in the waterdrop area 13. Multiple source lines 4 are disposed on the upper surface of the lower substrate 1. One end of each source line 4 is bonded to the driver IC 2, and the other end of each source line 4 passes through the display area 11 and is bonded to the rapid detection PAD 3. Due to series voltage division, the resistance varies from the driver IC 2 to the top of the display area 11 because the lengths of the source lines 4 at different pull-out positions are different. Furthermore, many coupling capacitors are generated when the driver IC 2 reaches the top of the display area 11, all of which contribute to voltage division, resulting in different potentials at different positions of the source lines 4. This means that in traditional position measurements, the loss caused by voltage division is not measured, leading to low effectiveness of the rapid detection data. Since the fast test PAD3 is located on the top waterdrop area 13 of the display area 11, meaning the fast test line is pulled out from the top waterdrop area 13 of the display area 11, it can test the potential of the output signal of the driver IC2 to the fanout area and after passing through the display area 11. This allows for a complete test of the actual displayed potential, improving the validity of the fast test data. Furthermore, since the waterdrop area 13 typically has no traces, it will not affect the traces in the waterdrop area 13. Moving the fast test PAD3 from the bonding area 12 to the waterdrop area 13 reduces the area occupied by the bonding area 12, making the space in the bonding area 12 more available.

[0033] Example 2, please refer to Figures 2 to 5As a further optimization of Embodiment 1, in this embodiment, the binding area 12 is bound to an FPC5. The surface of the FPC5 is provided with a traceability label 6 and a shielding paper 7. The traceability label 6 is pasted on the surface of the FPC5, and the shielding paper 7 covers the surface of the FPC5 and the traceability label 6. The shielding paper 7 includes a shielding layer 71, an adhesive layer 72 and a non-adhesive layer 73, which are stacked sequentially from top to bottom. The size and position of the non-adhesive layer 73 correspond to the size and position of the traceability label 6. The non-adhesive layer 73 covers the traceability label 6, and the adhesive layer 72 covers the surface of the FPC5. Since the bottom layer of the shielding paper 7 is provided with a non-adhesive layer 73, and the non-adhesive layer 73 covers the traceability label paper 6, while the adhesive layer 72 covers other areas on the surface of the FPC5, by adding a non-adhesive layer 73 in the corresponding area of ​​the traceability label paper 6, the adhesiveness of the shielding paper 7 is isolated from the traceability label paper 6, which can avoid the problem of the traceability code on the traceability label paper 6 being easily peeled off due to the adhesiveness of the shielding paper 7 during rework, and improve the traceability of product accessories.

[0034] Furthermore, the thickness of the non-adhesive layer 73 is 0.03mm-0.06mm. The edge of the non-adhesive layer 73 extends 1.5mm to 3mm beyond the edge of the traceability label 6 to ensure that, even with application deviations, the non-adhesive layer 73 still completely covers the traceability label 6. Additionally, the non-adhesive layer 73 and the shielding layer 71 have different appearance colors so that it is easy to visually distinguish whether there are any omissions in the non-adhesive layer 73, ensuring product consistency. More preferably, the non-adhesive layer 73 is white and the shielding layer 71 is black; using white and black allows for better differentiation between the non-adhesive layer 73 and the shielding layer 71.

[0035] Furthermore, the cross-sectional area of ​​the shielding paper 7 is larger than that of the traceability label paper 6. In this embodiment, the cross-sectional area of ​​the shielding paper 7 is 1.5 times that of the traceability label paper 6. The shielding paper 7 completely covers the traceability label paper 6 to further protect the traceability label paper 6.
