[0030] In the present embodiment, the first clamping unit 31 includes a cylindrical structure and is configured to roll up the flexible display 1, but the present disclosure is not limited thereto. The first clamping unit 31 may include any other appropriate shape. For example, the first clamping unit 31 may be curved or rod-shaped in order to roll up the flexible display 1.
[0031] In general, if the flexible circuit board 6 is inserted into a terminal socket of a lighting jig, the flexible display 1 at the corresponding end cannot be rolled up because the terminal socket of the lighting jig cannot be rolled up. According to the present disclosure, the flexible circuit board 6 is clamped by the first clamping unit 31. With the first clamping unit 31 including a cylindrical structure, the flexible display 1 at the corresponding end can be rolled up relative to the first clamping unit 31.
[0032] Referring to
[0033] In some embodiments, the first mechanical component 3 further includes a first vertical movement unit 33. The first vertical movement unit 33 drives the flexible display 1 to move vertically. The first vertical movement unit 33 connects to the first end 1A of the flexible display 1 through the first clamping unit 31. The first vertical movement unit 33 drives the first clamping unit 31 to move vertically so as to drive the flexible display 1 to move vertically. According to the present disclosure, the first vertical movement unit 33 may be, for example, a motor and ball bearing screw, but the present disclosure is not limited thereto.
[0034] The second mechanical component 4 includes the second clamping unit 41. The second clamping unit 41 clamps the second end 1B of the flexible display 1 and rolls up the flexible display 1. In some embodiments, both the second clamping unit 41 and the first clamping unit 31 are cylindrical. Similarly, the second clamping unit 41 may include an opening extending in an axial direction not only for clamping the flexible circuit board 6 but also for clamping the second end 1B of the flexible display 1, but the present disclosure is not limited thereto. The second clamping unit 41 may have other appropriate structures.
[0035] In some embodiments, the second mechanical component 4 may include a second rolling unit 42. The second rolling unit 42 connects to the second clamping unit 41. The second rolling unit 42 rolls the second clamping unit 41 forward or backward so as to roll up or unroll the flexible display 1. The second rolling unit 42 may include a second forward/backward servo motor (not shown in the drawings). The second forward/backward servo motor connects to the second clamping unit 41. The second forward/backward servo motor rolls up or unrolls the flexible display 1 through the second clamping unit 41.
[0036] The second mechanical component 4 may further include a second vertical movement unit 43. The second vertical movement unit 43 drives the flexible display 1 to move vertically. The second vertical movement unit 43 connects to the second end 1B of the flexible display 1 through the second clamping unit 41. The second vertical movement unit 43 drives the second clamping unit 41 to move vertically so as to drive the flexible display 1 to move vertically. According to the present disclosure, the second vertical movement unit 43 may be, for example, a motor and ball bearing screw, but the present disclosure is not limited thereto.
[0037] Alternatively, the testing tool 100 may further include a middle support component 9. The middle support component 9 is disposed on the plane 21 and located between the first mechanical component 3 and the second mechanical component 4. The middle support component 9 supports the flexible display 1 when the two ends of the flexible display 1 move vertically, thereby allowing the flexible display 1 to be folded.
[0038] For example, when the first vertical movement unit 33 and the second vertical movement unit 43 drive two ends of the flexible display 1 to move upward, the middle support component 9 is positioned over the flexible display 1 and in contact with the flexible display 1 such that the flexible display 1 folds upward. Accordingly, the testing tool 100 allows the rolling testing to be performed on the flexible display 1 in the upward folded state.
[0039] When the first vertical movement unit 33 and the second vertical movement unit 43 drive two ends of the flexible display 1 to move downward, the middle support component 9 is positioned under the flexible display 1 and in contact with the flexible display 1 such that the flexible display 1 folds downward. Accordingly, the testing tool 100 allows the rolling testing to be performed on the flexible display 1 in the downward folded state.
[0040] As shown in
[0041] Referring to
[0042] When the first clamping unit 31 rolls up the flexible display 1, and the second clamping unit 41 rolls up the flexible display 1, testing can be performed on the flexible display 1 with two ends rolled up. When the first clamping unit 31 unrolls the flexible display 1, and the second clamping unit 41 unrolls the flexible display 1, testing can be performed on the flexible display 1 with two ends unrolled.
[0043] When the first clamping unit 31 rolls up the flexible display 1 and the second clamping unit 41 unrolls the flexible display 1, or when the first clamping unit 31 unrolls the flexible display 1 and the second clamping unit 41 rolls up the flexible display 1, testing can be performed on the flexible display I with one end rolled up and the other end unrolled.
[0044] Furthermore, the first vertical movement unit 33 of the first mechanical component 3 and the second vertical movement unit 43 of the second mechanical component 4 may drive the flexible display 1 to move vertically such that testing may be performed on the flexible display 1 in the folded and rolled-up state.
[0045] As shown in
[0046] The sequence of operations of the first mechanical component 3 and the second mechanical component 4 is not limited to the aforementioned description, and the sequence of operation of the first mechanical component 3 and the second mechanical component 4 is subject to changes in accordance with the required folded and rolled-up state of the flexible display 1 in the course of the testing. Furthermore, the first mechanical component 3 and the second mechanical component 4 may roll up or fold the flexible display 1 separately or simultaneously, and the present disclosure is not restrictive of whether the rolling precedes or follows the folding. For example, the first mechanical component 3 rolls up the flexible display 1 or moves the flexible display 1 vertically, and then the second mechanical component 4 rolls up the flexible display 1 or moves the flexible display 1 vertically, but the present disclosure is not limited thereto. In a variant embodiment, both the first mechanical component 3 and the second mechanical component 4 roll up or vertically move the flexible display 1 simultaneously.
[0047] Referring to
[0048] The testing tool 100 may further include a second horizontal movement component 8. The second horizontal movement component 8 is disposed on the plane 21. The second horizontal movement component 8 drives the second mechanical component 4 to undergo a horizontal reciprocating movement in response to variations in the length of the rolled-up or folded flexible display 1. The second horizontal movement component 8 connects to the second mechanical component 4 so as to drive the second mechanical component 4 to undergo a horizontal reciprocating movement relative to the plane 21. The second horizontal movement component 8 may be, for example, a motor and ball bearing screw, but the present disclosure is not limited thereto.
[0049] The testing tool 100 may further include a control unit 13. The control unit 13 controls the first mechanical component 3 and the second mechanical component 4. The control unit 13 electrically connects to the first mechanical component 3 and the second mechanical component 4 so as to control the first mechanical component 3 and the second mechanical component 4 to roll or move.

To simplify the description and for the convenience of comparison between each of the embodiments of the present disclosure, the identical components in each of the following embodiments are marked with identical numerals. For making it easier to compare the difference between the embodiments, the following description will detail the dissimilarities among different embodiments and the identical features will not be redundantly described.
[0051] Referring to
[0052] The second clamping unit 41 may include two clamping blocks disposed vertically symmetrical to each other. The second end 1B of the flexible display 1 is clamped by and between the two clamping blocks. Therefore, the second clamping unit 41 clamps and fixes the flexible display 1 in place, using the two clamping blocks. The second clamping unit 41 clamps the flexible display 1 such that the second vertical movement unit 42 drives the second clamping unit 41 to move so as to drive the flexible display 1 to move vertically. The second clamping unit 41 may be, for example, a clamp, but the present disclosure is not limited thereto.

[0065] 3. A first vertical movement unit of the first mechanical component, a second vertical movement unit of the second mechanical component, and a middle support component together allow testing of the flexible display while the flexible display is folded upward and downward;
[0066] 4. With a plurality of middle support components, a plurality of third vertical movement units drive the middle of the flexible display to move vertically, while the first vertical movement unit and the second vertical movement unit drive two ends of the flexible display to move vertically, thereby allowing testing to be performed on the flexible display folded in various ways; and
[0067] 5. The first vertical movement unit, the second vertical movement unit, and the middle support components drive the flexible display to be folded, and the forward/backward servo motors drive the flexible display to be rolled up and unrolled, thereby allowing testing to be performed on the flexible display in folded and rolled-up states simultaneously.
