Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] The embodiments of the present application provide a binding structure of a flexible display panel, a method for using the same and a flexible display panel. The binding structure of the flexible display panel can be used for flexible display panels such as smart phones, tablet computers and display screens during lighting test.

[0035] As Figure 1 , Figure 2As shown, it is a structural schematic diagram of a flexible display panel, wherein the flexible display panel 100 is provided with a display area 110, a fan-out area 120, a binding area 130, a lighting connection area 140 and a connection area 150, wherein the display unit wiring of the display area 110 is connected to the fan-out wiring in the fan-out area 120. In order to save space, the fan-out wiring is inclined relative to the boundary line between the display area 110 and the fan-out area 120, and a binding structure 10 of the flexible display panel connected to the fan-out wiring is provided in the binding area 130 and the lighting connection area 140.

[0036] like Figure 2 As shown, the flexible display panel's binding structure 10 includes a binding pad 1 for binding and a lighting pad 2 for connecting to a lighting device. The lighting pad 2 utilizes a linear structure, facilitating full-contact lighting connection with the lighting device, preventing misalignment and potentially causing short circuits and burns in the fixture. Furthermore, after the lighting test is completed, the lighting pad 2 of the flexible display panel's binding structure 10 is removed, while the binding pad 1 remains. This maintains the quality of the finished flexible display panel 100.

[0037] Furthermore, the retained inclined binding pad 1 can prevent the flexible display panel 100 from dimensional expansion after the laser lift-off process, thereby reducing the impact of the expansion on the module binding process.

[0038] The binding structure 10 of the flexible display panel in this embodiment is suitable for the production of display screens of flexible display panels 100 such as OLED, LED, and mini LED, and is especially suitable for the lighting test link of the flexible display panel 100. It is preferably used in the OLED display screen production process, which can effectively improve the yield.

[0039] For details, please refer to Figure 2 The binding structure 10 of the flexible display panel includes a plurality of binding pads 1 and a plurality of lighting pads 2. The binding pads 1 are arranged obliquely relative to the boundary line between the display area 110 and the binding area 130, and the lighting pads 2 are arranged perpendicular to the boundary line between the display area 110 and the binding area 130.

[0040] Among them, multiple binding pads 1 are arranged in the binding area 130 of the flexible display panel 100, and the first end of the binding pad 1 is electrically connected to the display area 110 of the flexible display panel 100; the extension direction of the binding pad 1 forms an angle with the extension direction of the binding area 130, and the binding pads 1 on both sides of the binding area 130 are arranged in mirror symmetry. Multiple lighting pads 2 are arranged perpendicular to the extension direction of the binding area 130 and electrically connected to the second end of the binding pad 1, and the lighting pad 2 is located on the side away from the display area 110, for electrical connection to the lighting device; the lighting pad 2 is cut off after the lighting test is completed, and the cutting direction is parallel to the boundary line between the display area 110 and the binding area 130, that is, the cutting direction is the boundary line between the binding pad 1 and the lighting pad 2, see for details.Figure 2 The cutting path in Figure 2 Indicated by dotted line.

[0041] like Figure 2 、 Figure 3 、 Figure 4 As shown, all lighting pads 2 are arranged perpendicular to the extension direction of the binding area 130, so that all lighting pads 2 are arranged parallel to each other, which is convenient for full contact connection with the lighting device. Even if the movement direction of the needle mechanism is offset during the connection process (the probe pad 20 is offset in the direction of the probe pad 20), the probe pad 20 is not in the direction of the probe pad 20. Figure 4 There will be no display anomalies or fixture short circuit and burnout, which can improve product yield and greatly increase equipment utilization rate.

[0042] like Figure 2 、 Figure 3 、 Figure 4 As shown, in this embodiment, the bonding pad 1 includes a first inclined pad 11 and a second inclined pad 13 , and the first inclined pad 11 and the second inclined pad 13 are symmetrically arranged on both sides of the bonding area 130 .

[0043] like Figure 2 、 Figure 3 、 Figure 4 As shown, in this embodiment, all first inclined pads 11 have equal angles with the lighting pad 2; all second inclined pads 13 have equal angles with the lighting pad 2. In other words, the first and second inclined pads 11, 13 are mirror images arranged on the left and right sides of the bonding area 130. The inclined arrangement of the bonding pads 1 prevents dimensional expansion of the flexible display panel 100 after the laser lift-off process, minimizing the impact of this expansion on the module bonding process.

[0044] like Figure 2 、 Figure 3 、 Figure 4 As shown, in this embodiment, the binding pads 1 further include a middle vertical pad 12, which is located between the first inclined pad 11 and the second inclined pad 13. The middle vertical pad 12 is arranged perpendicular to the extension direction of the binding area 130, and the middle vertical pad 12 is located on the same straight line as the lighting pad 2. It is understood that the axis of symmetry of the middle vertical pad 12 preferably coincides with the axis of symmetry of the first inclined pad 11 and the second inclined pad 13.

[0045] In this embodiment, the first end of the bonding pad 1 is electrically connected to the fan-out trace, and the bonding pad 1 is electrically connected to the display area 110 of the flexible display panel 100 through the fan-out trace. The extension direction of the bonding pad 1 is preferably consistent with the extension direction of the fan-out trace, so that the bonding pad 1 and the fan-out trace are located on the same straight line to avoid stress during flexible bending.

[0046] In this embodiment, if Figure 3 、 Figure 4 As shown, the lighting device includes a probe pad 20, which is electrically connected to the lighting pad 2. The length of the lighting pad 2 is greater than or equal to the length of the probe pad 20. The probe pad 20 is provided with a plurality of probe holes, which are used to guide the needle. In this way, during the full contact connection between the lighting pad 2 and the lighting device, even if the movement direction of the needle mechanism is offset (the probe pad 20 is offset in the direction of the needle movement), the probe pad 20 can be connected to the lighting device in a non-contact manner. Figure 4 There will be no display anomalies or fixture short circuit and burnout, which can improve product yield and greatly increase equipment utilization rate.

[0047] like Figure 1 As shown, the embodiment of the present application provides a flexible display panel 100, which includes a display area 110 and a binding area 130 located on one side of the display area 110; a plurality of binding pads 1 are provided in the binding area 130, and the first end of each binding pad 1 is electrically connected to the display area 110 of the flexible display panel 100; the extension direction of the binding pad 1 forms an angle with the extension direction of the binding area 130, and the binding pads 1 located on both sides of the binding area 130 are arranged in mirror symmetry; a plurality of lighting pads 2 are provided in the extension direction perpendicular to the binding area 130, each lighting pad 2 is electrically connected to the second end of the binding pad 1, and the lighting pad 2 is located away from the display area 110, and is used to electrically connect to the lighting device ( Figure 3 、 Figure 4 The lighting pad 2 is cut off after the lighting test is completed, and the cutting direction is parallel to the boundary line between the display area 110 and the binding area 130, that is, the cutting direction is the boundary line between the binding pad 1 and the lighting pad 2, see Figure 2 The cutting path in Figure 2 Indicated by dotted line.

The first inclined pad 11 and the second inclined pad 13 are symmetrically arranged on both sides of the binding area 130, and the middle vertical pad 12 is located between the first inclined pad 11 and the second inclined pad 13; the angles between all first inclined pads 11 and the lighting pad 2 are equal, the angles between all second inclined pads 13 and the lighting pad 2 are equal, the middle vertical pad 12 is arranged perpendicular to the extension direction of the binding area 130, and the middle vertical pad 12 and the lighting pad 2 are located on the same straight line.

[0049] In this embodiment, if Figure 1As shown, the flexible display panel 100 further comprises a fan-out area 120 between the display area 110 and the binding area 130, and the fan-out area 120 is provided with fan-out wires; the first end of the binding pad 1 is electrically connected to the fan-out wires, and the binding pad 1 is electrically connected to the display area 110 of the flexible display panel 100 through the fan-out wires.

Moreover, after the lighting test is completed, the lighting pad 2 in the binding structure 10 of the flexible display panel is cut off while the binding pad 1 is retained, and the quality of the prepared flexible display panel 100 product is not affected. Moreover, the retained inclined binding pad 1 can avoid the phenomenon of size expansion of the flexible display panel 100 after the corresponding laser ablation process, thereby reducing the influence of expansion on the module binding process.
