[0002] With the rapid development of display panels, the market demand for mobile phone screens is increasing, and consumers are pursuing better display effects, leading to a greater variety of products. Consequently, manufacturers are imposing stricter quality requirements, often needing to rigorously control performance parameters such as dead pixels, brightness defects, viewing angles, reflectivity, contrast ratio, and color temperature before allowing qualified products to enter the market.

[0003] As more and more display panels with fingerprint sensors become available, existing testing structures can only press the display panel during fingerprint detection, but cannot display the fingerprint test pressure value or adjust the fingerprint test pressure value. This makes it impossible to guarantee that the force applied to the display panel is within the set range during fingerprint testing. Utility Model Content

[0037] Example:

[0038] Figure 1 This is a schematic diagram of a fingerprint testing structure for a display panel provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the fingerprint testing structure includes an active plate 1, a pressure sensor 2, and a fingerprint testing component 3.

[0039] The movable plate 1 is movably arranged on the carrier plate 100, and the pressure sensor 2 is inserted into the carrier plate 100.

[0040] Figure 2 This is a top view of the fingerprint testing component provided in this embodiment of the present invention. Figure 3 This is a cross-sectional view along direction AA of the fingerprint testing component provided in this embodiment of the utility model, combined with... Figure 2 and Figure 3 As shown, the fingerprint testing component 3 includes a pressing block 31, a fingerprint module 32, and a pressure adjustment mechanism 33. The pressing block 31 is slidably inserted into the movable plate 1 along the first direction (Z-axis direction). The fingerprint module 32 is arranged opposite to the pressing block 31 and the distance between them is adjustable. A first elastic element 34 is sandwiched between the pressing block 31 and the fingerprint module 32. The fingerprint module 32 is used to press the fingerprint area of ​​the display panel. The top of the pressure adjustment mechanism 33 is a T-shaped structure. The pressing block 31 is provided with a stepped hole. The T-shaped structure of the pressure adjustment mechanism 33 slides with the stepped hole. The bottom of the stepped hole limits the T-shaped structure. The bottom of the pressure adjustment mechanism 33 passes through the stepped hole and connects to the fingerprint module 32.

[0041] In the fingerprint testing structure for a display panel provided in this embodiment of the present invention, when performing fingerprint testing on the display panel, firstly, the movable plate 1 and the pressure sensor 2 are mounted on a carrier plate, and the display panel is placed horizontally on the carrier plate. The pressure sensor 2 is inserted into the top of the carrier plate. When the display panel is compressed, it will compress the pressure sensor 2, thereby allowing the pressure to be read. Then, the display panel is made conductive. The position of the movable plate 1 on the carrier plate is adjusted so that the movable plate 1 moves above the display panel and is parallel and spaced apart from the display panel. At this time, the fingerprint module 32 is also spaced apart from the display panel (see...). Figure 4 Next, the pressing block 31 is pressed down, and under the conductive force of the first elastic element 34 (which is always in a compressed state), the pressing block 31 drives the fingerprint module 32 to move vertically downward together. The restoring force generated by the first elastic element 34 causes the fingerprint module 32 to press the fingerprint area on the display panel. At this time, the pressure sensor 2 can directly read the fingerprint pressure value (see...). Figure 5 When the fingerprint pressure value is below or exceeds the set range, the pressure on the display panel can be released (i.e., the entire fingerprint testing component can be moved upwards). The vertical position of the fingerprint module 32 relative to the pressing block 31 can be adjusted by the pressure adjustment mechanism 33, thereby adjusting the compression of the first elastic element 34 and its restoring force (i.e., adjusting the force exerted by the first elastic element 34 on the fingerprint module 32 and the display panel). Press the pressing block 31 again and repeat the above steps until the fingerprint pressure value displayed on the pressure sensor 2 reaches the set range, thus achieving accurate testing. When testing the next display panel of the same batch, there is no need to adjust the fingerprint pressure value again; simply move the pressing block 31 down to the same height.

[0042] In other words, the fingerprint testing structure for a display panel provided by this utility model embodiment can display and adjust the fingerprint pressure value on the fingerprint area of ​​the display panel, ensuring that the force on the display panel is within a set range during fingerprint testing, thereby achieving accurate testing.

[0043] It should be noted that after the test is completed, the pressing block 31 is moved up so that the fingerprint test component 3 is moved up to a distance from the display panel. Then the movable plate 1 is moved and the display panel is removed.

[0044] For example, the pressure sensor and the fingerprint module are arranged facing each other in the first direction.

[0045] In one implementation of this utility model, the pressure adjustment mechanism 33 is a T-bolt, the bottom end of which is threaded into the fingerprint module 32. That is, the distance between the pressing block 31 and the fingerprint module 32 is adjusted by threading, thereby adjusting the compression of the first elastic element 34. After adjustment, the pressure adjustment mechanism 33 and the fingerprint module 32 can also be connected. Alternatively, adjustment can be made by pressing the display panel on the fingerprint module 32; that is, by turning the T-bolt, the pressure sensor reading can be taken in real time until the fingerprint pressure value displayed by the pressure sensor reaches the set range, thereby improving adjustment efficiency and accuracy.

[0046] It should be noted that in other embodiments of this utility model, the pressure adjustment mechanism 33 can also be connected to the fingerprint module 32 by means of a positioning pin and a corresponding positioning hole after the distance between the fingerprint module 32 and the pressing block 31 is adjusted, or by means of a telescopic rod, etc. This utility model does not limit this.

[0047] In this embodiment, the movable plate 1 has a through hole 11, the bottom of the pressing block 31 is provided with a first ring body 313, the top of the fingerprint module 32 is provided with a second ring body 35, the second ring body 35 is slidably inserted into the through hole 11, the first ring body 313 is slidably inserted into the second ring body 35, and the first elastic member 34 is located inside the first ring body 313 and the second ring body 35.

[0048] In the above embodiment, the through hole 11 guides the sliding of the fingerprint module 32, while the second ring 35 guides the sliding of the pressing block 31.

[0049] Additionally, the fingerprint module 32 includes a connecting block 321 and a fingerprint block 322. A first elastic element 34 is sandwiched between the connecting block 321 and the pressing block 31, and the distance between them is adjustable. The fingerprint block 322 is inserted into the connecting block 321 and extends out of the connecting block 321. The fingerprint block 322 is used to press the fingerprint area on the display panel. The connecting block 321 and the pressing block 31 are in sliding engagement. The connecting block 321 guides the sliding of the fingerprint block 322, while the fingerprint block 322 can simulate a human finger to press the fingerprint area on the display panel.

[0050] For example, the fingerprint module 32 also includes a connector 323, the bottom of which is threadedly engaged with the connector block 321, and the pressure adjustment mechanism 33 is threadedly engaged with the top of the connector 323.

[0051] In one implementation of this utility model, the movable plate 1 is rotatably arranged on the carrier plate, that is, the position of the fingerprint testing component 3 is switched by flipping the movable plate 1, which facilitates the picking and placing of the display panel.

[0052] For example, when the movable plate 1 is not flipped over the carrier plate, the display panel can be freely placed and removed. When the movable plate 1 is flipped into place, it is parallel to the display panel, and the fingerprint testing component 3 is perpendicular to the display panel.

[0053] Furthermore, the fingerprint testing structure also includes a hinge base 4 and a limiting base 5. Both the hinge base 4 and the limiting base 5 are used to fix the movable plate 1 to the carrier plate. One side of the movable plate 1 is hinged to the hinge base 4, and the limiting base 5 has a second hook 51 movably arranged on it. The second hook 51 is used to hook the other side of the movable plate 1. That is, when the movable plate 1 is flipped into place by the hinge base 4, the second hook 51 can lock the movable plate 1. At this time, the movable plate 1 is parallel to the display panel, preventing the movable plate 1 from being accidentally opened or rotated.

[0054] For example, when the movable plate 1 is flipped into place by the hinge seat 4, the other side of the movable plate 1 rests on the limiting seat 5, thereby achieving reliable support for the movable plate 1.

[0055] It should be noted that in other embodiments of this utility model, the movable plate 1 can also be mounted on the carrier plate by rotation or sliding, which can achieve position adjustment of the fingerprint testing component 3. This utility model does not limit this.

[0056] Figure 6 This is a schematic diagram of the structure of the pressing block provided in an embodiment of this utility model, as shown below. Figure 6 As shown, the outer peripheral wall of the pressing block 31 has a boss 311, and a second elastic element 36 is sandwiched between the boss 311 and the movable plate 1 (see...). Figure 4 ).

[0057] In the above embodiment, the second elastic member 36 can move the entire fingerprint testing component 3 upward and reset after the fingerprint test is completed, so as to prepare for the next press and move downward, and at the same time facilitate the removal and placement of the display panel after the movable plate 1 is moved.

[0058] For example, the boss 311 and the movable plate 1 have positioning grooves, and both ends of the second elastic member 36 are inserted into the positioning grooves.

[0059] Furthermore, each of the two oppositely arranged sides of the pressing block 31 is hinged with a first hook 312. The movable plate 1 has a fixed shaft 12. The hooking part of the first hook 312 has an inclined surface, and the first hook is used to hook the fixed shaft. This inclined surface allows the lower hooking part to rotate below the fixed shaft after the pressing block 31 moves down, so that the first hook 312 can hook the fixed shaft 12, thereby locking the pressing block 31 through the first hook and preventing prolonged pressing after the pressing block 31 moves down. In addition, a rotating shaft 3121 is provided on the first hook 312, and the first hook 312 is rotatably sleeved on the rotating shaft 3121.

[0060] For example, a first hook 312 is hinged to the side of the pressing block 31. The first hook 312 is configured such that when the protrusion 311 abuts against the movable plate 1, the first hook 312 hooks onto the movable plate 1; when the protrusion and the movable plate are separated, the first hook 312 is located on one side of the movable plate (i.e., not hooked). On the one hand, the protrusion 311 can limit the pressing block 31, preventing the fingerprint testing component 3 from moving down too far and damaging the display panel. On the other hand, when the pressing block 31 moves down to the limit position where the protrusion 311 contacts the movable plate 1, the first hook 312 hooks onto the movable plate 1 to limit the upper part of the movable plate 1, thereby locking the pressing block 31 and preventing prolonged pressing of the pressing block 31.

[0061] For example, a third elastic element 37 is sandwiched between the side of the first hook 312 facing away from the hook end and the pressing block 31 (see...). Figure 3 The third elastic element 37 can drive the first hook 312 to rotate during the pressing and downward movement of the pressing block 31, thereby achieving the function of automatically hooking and locking the first hook 312 onto the movable plate 1. In addition, after the test is completed, rotating the first hook 312 releases the lock on the movable plate 1, at which point the fingerprint test component 3 can be moved upward.

[0062] It should be noted that in other embodiments of this utility model, the first hook 312 can be automatically hooked and locked to the movable plate 1 by setting a torsion spring on the rotating shaft of the first hook 312.

[0063] For example, the number of first hooks 312 on the pressing block 31 is two and they are symmetrically arranged on opposite sides of the pressing block 31. This not only allows for uniform force on the pressing block 31 when it is locked by hooking, but also makes it easy to unlock by pressing the first hooks 312 with two fingers respectively.

[0064] For example, the elastic element can be a spring.

[0065] See you again Figure 1 An adjustment module 6 is provided on the movable plate 1. The adjustment module 6 is used to adjust the position of the pressing block 31 on the movable plate 1 along the second direction and the third direction.

[0066] Furthermore, the adjustment module 6 includes a first adjustment plate 61 and a second adjustment plate 62. The first adjustment plate 61 has a first oblong hole 611 arranged along the second direction (X-axis direction), and a first connecting bolt is inserted into the first oblong hole 611 to connect the movable plate 1. The second adjustment plate 62 has a second oblong hole 621 arranged along the third direction (Y-axis direction), and a second connecting bolt is inserted into the second oblong hole 621 to connect the first adjustment plate 61. The pressing block 31 is slidably inserted into the second adjustment plate 62. That is, the position of the second adjustment plate 62 and the pressing block 31 in the second direction can be adjusted through the first oblong hole 611 and the first connecting bolt, and the position of the pressing block 31 in the third direction can be adjusted through the second oblong hole 621 and the second connecting bolt, thereby ultimately adjusting the position of the fingerprint module 32 to adapt to the fingerprint area of ​​different types of display panels (the position of the fingerprint area is different for different types of display panels).

[0067] For example, the through hole 11 also extends into the adjustment module 6, and the pressing block 31 and the fingerprint module 32 are slidably arranged on the adjustment module 6.

[0068] For example, there can be two or four first oblong holes 611 and second oblong holes 621, and they are arranged at intervals at corresponding right-angle positions. This utility model does not limit this. The arrangement of multiple oblong holes can ensure more stable installation of the adjusting plate and pressing block, and more precise position adjustment.

[0069] In addition, a set screw 63 is inserted on the first adjustment plate 61, through which the height of the second adjustment plate 62 and the fingerprint testing component 3 can be adjusted, which can also adapt to display panels of different thicknesses.

[0070] It should be noted that in other embodiments of this utility model, the position of the fingerprint testing component 3 on the movable plate 1 can also be adjusted by other adjustment structures, such as slide rails or positioning pins and positioning holes.

[0071] Figure 7 This is a structural schematic diagram of a crimping fixture provided in an embodiment of this utility model, as shown below. Figure 7 As shown, the crimping fixture includes a fingerprint testing structure for a display panel as described above.

[0072] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
