The specific configuration of the first rotating shaft 03 may be other forms as long as the angle between the stage 01 and the rotating plate 02 can be changed.
Referring to fig. 2, fig. 2 is an effect diagram of a display panel bending test fixture according to an embodiment of the present application, and fig. 2 is a top view of a position relationship between a display panel 20 and the test fixture at the beginning of a bending test. As shown in fig. 2, the display panel 20 includes a first portion 21, a second portion 22, and a bendable region 23, wherein the bendable region 23 is disposed between the first portion 21 and the second portion 22. Specifically, the first portion 21, the bendable region 23, and the second portion 22 are connected in sequence. The bendable region 23 is a region of the display panel 20 that can be flexibly bent, and the bendable region 23 is at least a partial region of the region that can be flexibly bent.
The stage 01 includes a receiving structure for receiving the first portion 21 of the display panel 20. Alternatively, as shown in fig. 1, the receiving structure may include a first vacuum hole 012, and the first vacuum hole 012 may suck the first portion 21 of the display panel 20 to fix the first portion 21 of the display panel 20 on the stage 01.
Optionally, referring to fig. 3, fig. 3 is a schematic view of the object stage provided in an embodiment of the present application, and the accommodating structure of the object stage 01 may include a groove 011 and a slider 013, wherein the slider 013 is disposed in the groove 011 and can slide in the groove 011. The first portion 21 of the display panel 20 may be disposed in the groove 011 so as to be fixed to the stage 01, and in order to accommodate display panels 20 of different sizes, a slider 013 disposed in the groove 011 may be slid as necessary, and in particular, the first portion 21 of the display panel 20 may be firmly fixed in the groove 011 by adjusting the slider 013. Since the housing structure is intended to fix the first portion 21 of the display panel 20 to the stage 01, one or a combination of at least two of the groove 011, the slider 013, and the first vacuum hole 012 can be selected as necessary.
Referring to fig. 1, the rotating plate 02 includes a first fixing structure (not shown) and a second fixing structure 022. The first fixing structure is used for fixing the second portion 22 of the display panel 20, and in particular, the way in which the first fixing structure of the rotating plate 02 fixes the second portion 22 of the display panel 20 can be referred to the way in which the stage 01 fixes the first portion 21 of the display panel 20. For example, the first fixing structure includes a second vacuum hole for sucking the second portion 22 of the display panel 20 to fix the second portion 22 of the display panel 20 on the rotating plate 02. Wherein the second fixing structure 022 is used for fixing the circuit board 10, and the circuit board 10 can provide signals for the display panel 20, and in particular, the second portion 22 of the display panel 20 can be connected to the circuit board 10, so as to realize the signal transmission between the display panel 20 and the circuit board 10.
Specifically, please refer to fig. 1 and 4, fig. 4 is an effect diagram of a display panel bending test fixture according to another embodiment of the present application, and fig. 4 is a front view of a display panel 20 being subjected to a bending test by using the display panel bending test fixture shown in fig. 1. As shown in fig. 1, the housing structure of the stage 01 is provided on the side of the stage 01 facing the rotating plate 02, and the first fixing structure of the rotating plate 02 is provided on the side of the rotating plate 02 facing the stage 01. As shown in fig. 4, during the bending test, the angle between the stage 01 and the rotating plate 02 is changed, so that the angles of the first portion 21 and the second portion 22 of the display panel 20 are changed, thereby bending the bendable region 23. Meanwhile, the second portion 22 of the display panel 20 is connected with the circuit board 10 fixed on the rotation plate 02. Therefore, in the bending test process, the display panel 02 can obtain signals from the circuit board 10 to display a test picture.
In summary, when the bending test is performed on the display panel 20, the display panel 20 can obtain signals from the circuit board 10 to display a test screen, so that the display panel 20 does not need to be frequently removed from the test fixture. Meanwhile, the display panel 20 does not need to be taken down from the test fixture when the same display panel 20 is subjected to multiple bending tests, so that the fold lines are consistent when the display panel 20 is bent for multiple times. In addition, since the test screen of the display panel 20 can be seen in real time, it is possible to quickly and clearly know what the limit number of bending tests is.
It should be noted that, alternatively, the second fastening structure 022 of the rotary plate 02 may be arranged on the side of the rotary plate 02 facing away from the object table 01, as shown in fig. 1 and 4, and the circuit board 10 is thus also fastened on the side of the rotary plate 02 facing away from the object table 01. Alternatively, the second fixing structure 022 of the display panel 20 may be disposed on the side of the rotating plate 02 facing the stage 01, and correspondingly, the circuit board 10 may be fixed on the side of the rotating plate 02 facing the stage 01. Alternatively, the second fixing structure 022 of the display panel 20 may be disposed at a side surface of the rotating plate 02, and correspondingly, the circuit board 10 may be fixed at a side surface of the rotating plate 02.
It should be further noted that the second fixing structure 022 of the rotating plate 02 can be flexibly opened and closed. For example, the second fastening structure 022 includes a latch that can latch the circuit board 10 when closed and can remove the circuit board 10 when open. Thus, the circuit board 10 fixed by the second fixing structure 022 of the rotating plate 02 can be different according to different display panels 20, and thus, one fixture can be used for performing bending tests on a plurality of display panels 20. In addition, the second fixing structure 022 can also be other structures, such as screws, elastic pieces, and the like.
It should be noted that, in an embodiment of the present application, the first portion 21 of the display panel 20 includes a display area, the second portion 22 includes a flexible circuit board, and the bendable area 23 includes a pad and a fan-shaped trace. The bendable region 23 is connected to the first portion 21 (display region) of the display panel 20, and the second portion 22 (flexible circuit board) is bound to the pad connected to the fan-shaped trace in the bendable region 23. When the second portion 22 of the display panel is connected to the circuit board 10 fixed to the rotating plate 02, the first portion 21 (display area) of the display panel 20 can obtain a signal from the circuit board 10 to perform display. Since the fan-shaped traces in the bendable region 23 are usually made of metal or metal oxide, there is a risk of breakage during bending, and therefore it is necessary to perform a bending reliability test. In order to perform the bending test on the bendable region 23, as shown in fig. 2, the bendable region 23 is at least partially located between the stage 01 and the rotating plate 02 and is at least partially not fixed to the stage 01 and the rotating plate 02, so as to ensure that the bendable region 23 can be bent.
The rotating plate 02 is used to carry and fix the second portion 22 of the display panel 20 and fix the circuit board 10, and therefore, the rotating plate 02 needs to satisfy the above requirements. In addition, alternatively, as shown in fig. 2, the shape of the rotating plate 02 may be rectangular, and when different display panels 20 are tested and the shapes of the second portions 22 of the display panels 20 are different, the different second portions 22 may be carried and fixed by the rectangular rotating plate 02. Optionally, the shape of the rotating plate 02 may also be set according to the shape of the second portion 22 of the display panel 20, as shown in fig. 5, fig. 5 is an effect diagram of a display panel bending test fixture provided in another embodiment of the present application, and fig. 5 is a top view of a position relationship between the display panel 20 and the test fixture when the bending test starts; the flexible circuit board of the display panel 20 is generally "L" shaped, that is, the second portion 22 of the display panel 20 is generally "L" shaped, and therefore, the shape of the rotating plate 02 may also be set to be "L" shaped.
In order to realize an extremely narrow frame of the display panel 20, the bendable region 23, which is provided with fan-shaped traces, pads, and a flexible circuit board bound therein, in the display panel 20 is bent toward a backlight surface of the display panel 20, where the backlight surface is a surface opposite to a light emitting surface of the display panel 20, that is, a surface opposite to a side on which a test picture is displayed during a bending test. In the bending test of the display panel 20, the bendable region 23 of the display panel 20 should be bent toward the backlight surface of the display panel 20, that is, the second portion 22 of the display panel 20 is bent toward the backlight surface of the display panel 20, so as to drive the bendable region 23 to bend. Then, in the bending test of the display panel 20, when the bendable region 23 is bent, the backlight surface of the first portion 21 of the display panel 20 should face the rotating plate 02, that is, the light-emitting surface of the first portion 21 of the display panel 20 should face the accommodating structure of the stage 01.
In one embodiment of the present application, at least the position of the accommodating structure in the stage 01 is light-permeable. Since the light-emitting surface of the display panel 20 faces the accommodating structure, and the display panel 20 can perform a test screen display during the bending test of the display panel 20, the accommodating structure is transparent, so that the test screen condition of the display panel 20 can be more easily seen through the accommodating structure during the bending test of the display panel 20.
In an embodiment of the present application, please refer to fig. 6, and fig. 6 is a schematic view illustrating a display panel bending test fixture provided in another embodiment of the present application. The test fixture further comprises a mirror 04, specifically, the mirror 04 is arranged on one side of the object stage 01, which is far away from the accommodating structure, and the mirror surface of the mirror 04 faces the object stage 01. Since the mirror 04 is disposed on a side of the stage 01 away from the receiving structure, the light emitting surface of the display panel 20 faces the receiving structure, that is, the mirror 04 is opposite to the light emitting surface of the display panel 20. And the mirror surface of the mirror 04 faces the stage 01, that is, specifically, the mirror surface of the mirror 04 faces the light exit surface of the display panel 20. Therefore, during the bending test, the display condition of the test image on the light-emitting surface of the display panel 20 can be seen from the mirror 04 in real time.
In an embodiment of the present application, referring to fig. 7, fig. 7 is a diagram illustrating an effect of a display panel bending test fixture according to still another embodiment of the present application. Fig. 7 is a left side view of the display panel 20 tested by the testing fixture shown in fig. 6, in which the rotating plate 02 is rotated toward the stage 01 and then parallel to the stage 01, that is, the first portion 21 of the display panel 20 fixed on the stage 01 is parallel to the second portion 22 of the display panel 20 fixed on the rotating plate 02. Meanwhile, the second portion 22 of the display panel 20 is connected to the circuit board 20 fixed on the other side of the rotating plate 02, so that the light exiting surface of the display panel 20 facing the accommodating structure side (i.e., the downward side) of the stage 01 can display the test picture. The mirror 04 under the stage 01 can reflect the test picture on the light-emitting surface side of the display panel 20, and the human eye on the side of the test fixture can see the test picture reflected by the mirror 04, and thus can see the test picture on the light-emitting surface of the display panel 20.
It should be noted that, when the display panel 20 is subjected to the bending test, the angle of the bendable region 23 may be bent as needed, and the first portion 21 of the display panel 20 after bending may be parallel to the second portion 22, or may be at another angle.
In addition, in order for the human eye to see the picture on the mirror 04, the mirror 04 should be at a certain angle to the stage 01. Alternatively, the mirror 04 and the object table 01 may be at a fixed angle, for example, the angle between the mirror 04 and the object table 01 may be 45 °.
Optionally, as shown in fig. 7, the mirror 04 may be connected to the object stage 01 through a second rotating shaft 05, the second rotating shaft 05 rotates to drive the angle between the mirror 04 and the object stage 01 to change, and the tester may reasonably adjust the angle between the mirror 04 and the object stage 01 according to actual conditions, such as height of the tester, so as to accurately obtain the test picture condition of the display panel 20. Preferably, the rotation angle of the second rotating shaft 05 is controllable and fixable, that is, the angle between the mirror 04 and the stage 01 can be accurately fixed at one position, so that when bending tests are performed on display panels 20 with different sizes or bending tests are performed by different testers, the second rotating shaft 05 can be rotated to a specific position according to experience, that is, the angle between the mirror 04 and the stage 01 is fixed at a specific angle, so as to facilitate obtaining of a test picture.
The specific position of the second rotating shaft 05 may be set on the left side of the stage 01 as shown in fig. 7, or may be set on the right side of the stage 01. The second rotating shaft 05 may be provided on the same side of the stage 01 as the first rotating shaft 03, or the second rotating shaft 05 and the first rotating shaft 03 may be provided on different sides of the stage 01 as shown in fig. 6. The present application does not specifically limit the positional relationship between the second rotating shaft 05 and the first rotating shaft 03.
In addition, the area of the mirror 04 should be larger than or equal to the area of the receiving structure in the stage 01, so that the whole test picture of the first portion 21 of the display panel 20 in the receiving structure can be seen at an angle.
In an embodiment of the present application, please refer to fig. 8, fig. 8 is an effect diagram of a display panel bending test fixture provided in another embodiment of the present application, and fig. 8 is a top view of a position relationship between a display panel 20 and the test fixture when a bending test is started. Specifically, the stage 01 further includes a third fixing structure 014 disposed at an edge of the stage 01, and specifically, the third fixing structure 014 is disposed at an edge of the stage 01 near the first rotating shaft 03 for fixing the partially bendable region 23 of the display panel 20 on the stage 01. The third fixing structure 014 can fix the partially bendable region 23 on the stage 01. Meanwhile, as the bending line at the bending position has certain requirements during the bending test, the third fixing structure 014 can fix a part of the bendable region 23, which is close to the first part 21, outside the bending line, so that the bendable region 23 can be just bent at the bending line when the second part 22 is changed in position.
It should be noted that the thickness of the third fixing structure 014 should not be too thick, so as to avoid the influence of the thickness on determining the position of the bending line and the influence of the bending of the bendable region 23 along the bending line, and optionally, the thickness of the third fixing structure 014 may be in a range of 0.3mm to 0.5 mm.
Preferably, with continued reference to fig. 8, the stage 01 further includes a marking ruler 015; the marking scale 015 and the third fixing structure 014 may be relatively moved in the length direction of the marking scale 015, that is, the marking scale 015 may position the third fixing structure 014. Specifically, the scale direction of the marking scale 015 is perpendicular to the longitudinal direction of the third fixing structure 014, and optionally, the scale direction of the marking scale 015 is parallel to the movable direction of the third fixing structure 014.
As shown in fig. 8, when the bending test is performed on the display panel 20, a part of the bendable region 23 of the display panel 20 is disposed between the stage 01 and the rotating plate 02, that is, the part of the bendable region 23 of the display panel 20 is disposed at the position of the first rotating shaft 03, and the part of the bendable region 23 of the display panel 20 is disposed at the edge of the stage 01 close to the first rotating shaft 03. It will be appreciated that there must be a fold line when the bendable region 23 is bent, and the position of the fold line can be either a variable or a fixed amount at the time of the test, but whether the position of the fold line is a variable or a fixed amount, the particular position of the fold line at each test should be known by the tester. The third fixing structure 014 may fix the bendable region 23 on the stage 01, and the edge of the bendable region 23 at the position fixed by the third fixing structure 014 may be used as a diagonal line. In addition, the third fixing structure 014 cooperates with the marking ruler 015 to perform position adjustment, that is, the position of the bendable region 23 fixed by the third fixing structure 014 is controllable, so that the position of the bending line is controllable.
In addition, optionally, the marking ruler 015 may be a micrometer, and may include coarse adjustment and fine adjustment buttons to ensure that the position of the third fixing structure 014 can be determined quickly and accurately.
It should be noted that, in order to control the bending line of the bendable region 23, the scale direction of the marking ruler 015 should be perpendicular to the bending line direction of the bendable region 23.
