[0002] The overall design space limit of high-end flagship products such as tablets and laptops has become a trend, resulting in the demand for ultra-thin display modules. At the same time, high resolution (PPI) and high refresh rate are also strong demands in the consumer market. This results in an increase in the width of the binding area between the flexible printed circuit (FPC) and the display panel (panel) on the display module and the circuit board (PCBA), which reduces the edge distance between the binding area and the circuit board and the boundary of the display module. As a result, the size of the insulating protective member (Tape) attached to the circuit board and the binding area of ​​the display panel for corrosion protection is limited. The insulating protective member cannot completely wrap the binding area, resulting in a decrease in the corrosion resistance of the display module.

[0035] The following descriptions of the embodiments are with reference to the attached diagrams to illustrate specific embodiments that the present application can be implemented in. The directional terms mentioned in the present application, such as [up], [down], [front], [back], [left], [right], [inside], [outside], [side], etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present application, rather than to limit the present application. In the figures, units with similar structures are represented by the same reference numerals. In the accompanying drawings, the thickness of some layers and regions is exaggerated for clear understanding and ease of description. That is, the size and thickness of each component shown in the drawings are arbitrarily shown, but the present application is not limited to this.

[0036] In view of the problem that the metal circuit of the display module is corroded and has poor functionality during the sweat or salt spray test, the inventor of the present application found in the research that: Figures 1 to 4 , Figure 1 The following is a schematic diagram of a planar structure of a display module. Figure 2 for Figure 1 The schematic diagram shows the module after the insulation protection film is attached. Figure 3 for Figure 1 A detailed schematic diagram showing the local accumulation of corrosive liquid in the module. Figure 4 for Figure 3 The simplified structure diagram of the local membrane layer of the display module is shown in Figure 2. Figure 1The display module 100' includes a display panel 10', a support member 20', a circuit board 40', a flexible circuit board 50' and a driver integrated circuit (IC) 60'. The flexible circuit board 50' is connected between the display panel 10' and the circuit board 40'. The driver integrated circuit is bound to the display panel 10'. The support member 20' is used to support the display panel 10'.

[0037] In order to achieve high resolution (PPI) and high refresh rate, the width of the binding area between the flexible circuit board 50' and the display panel 10' and the circuit board 40' on the display module 100' will be increased, so that the edge distance L' between the binding area and the circuit board 40' and the boundary of the display module 100' will be reduced. Figure 2 Due to the reduction of the edge distance L', the size of the insulating protection member 70' attached to the circuit board 40' and the surface of the display panel 10' in the binding area for corrosion protection is limited, and the insulating protection member 70' cannot completely wrap the binding area. Figure 3 and Figure 4 Since the insulating protection member 70' cannot completely wrap the binding area, the corrosion resistance of the display module 100' will be reduced. Therefore, during the sweat or salt spray test, the corrosive liquid CL will gather on the side of the binding area. The corrosive liquid CL will form a siphon effect from the small gaps on the side and enter the binding area, causing corrosion of the metal circuits on the display panel 10', resulting in poor functionality.

[0038] To this end, the present application provides a display module and a display device to improve the problem of metal circuit corrosion and poor functionality of the display module during sweat or salt spray tests.

[0039] Please refer to Figures 1 to 8 , Figure 5 A partial structural diagram of a display module provided in an embodiment of the present application is shown in FIG.

The flexible organic light-emitting diode display panel 10 has a flexible characteristic, so that the display panel 10 can be bent or folded, and then the binding area of ​​the display panel 10 can be folded back to the back side of the display panel 10 to achieve a narrow frame.

[0041] The support member 20 is disposed on the back side of the display panel 10, the back side is opposite to the light emitting layer, and the light emitting side refers to the side of the display module 100 displaying the picture. The support member 20 includes a first support portion 21 corresponding to the first plane portion 11 and a second support portion 22 corresponding to the second plane portion 12, so as to support the display panel 10 as a whole. Optionally, the support member 20 may include a first support layer, a buffer layer and a second support layer stacked, wherein the material of the first support layer includes polyethylene terephthalate (PET) and the like, the first support layer is disconnected at a position corresponding to the bending portion 13, so that the first support layer is designed in two sections, one section is arranged corresponding to the first plane portion 11, and the other section is arranged corresponding to the second plane portion 12. The material of the buffer layer includes foam, polyimide and the like, and the buffer layer is arranged corresponding to the first plane portion 11, but not corresponding to the second plane portion 12. The material of the second supporting layer includes a metal material such as stainless steel, and the second supporting layer is arranged corresponding to the first plane portion 11, but not corresponding to the second plane portion 12. That is, the first supporting portion 21 includes the first supporting layer, the buffer layer, and the second supporting layer which are stacked, and the second supporting layer includes the first supporting layer, but does not include the buffer layer and the second supporting layer.

One end of the flexible circuit board 50 is bound to the second plane portion 12 of the display panel 10, and the other end is bound to the circuit board 40. The driver integrated circuit 60 (integrated circuit, IC) is also bound to the second plane portion 12 of the display panel 10, and is spaced apart from the flexible circuit board 40. Of course, in some other embodiments, the driver integrated circuit 60 can also be bound to the flexible circuit board 50.

[0043] The padding member 30 includes a main body 31 and an extension 32. The main body 31 fits the first support portion 21 and the second support portion 22.

The extension 32 extends from the main body 31 to the circuit board 40, and at least part of the extension 32 is disposed near the end opening of the first cavity 501. By expanding the padding member 30 to form the extension 32, the corrosive liquid needs to pass through the extension 32 before invading the junction of the flexible circuit board 50 and the display panel 10, thereby increasing the length of the corrosive liquid intrusion path and reducing the risk of corrosion of the metal circuit on the display panel 10, so as to improve the problem of corrosion of the metal circuit and poor functionality of the display module 100 during sweat or salt spray tests.

[0044] Specifically, there is a second gap between the padding member 30 and the bending portion 13. The padding member 30 is used to make the bending portion 13 form a bending arc of a certain angle to avoid the circuit in the bending portion 13 from being broken, and the padding member 30 is also used to fix the second plane portion 12 on the first support portion 21.

[0045] Continue to refer to Figure 5 The extension portion 32 includes a first extension sub-portion 321 and a second extension sub-portion 322 connected to the first extension sub-portion 321. The first extension sub-portion 321 is located outside the first cavity 501 and is disposed close to the first cavity 501.

The orthographic projection of the second extension sub-portion 322 on the first support portion 21 is located inside the orthographic projection of the flexible circuit board 50 on the first support portion 21.

[0046] Optionally, the flexible circuit board 50 includes a bending portion 51 arranged close to the circuit board 40, and the end of the extension portion 32 is close to the starting end of the bending portion 51, for example, the end of the extension portion 32 is flush with the starting end of the bending portion 51, so that a certain distance is reserved between the extension portion 32 and the circuit board 40 to prevent the extension portion 32 from affecting the binding of the flexible circuit board 50 and the circuit board 40.

[0047] In one embodiment, referring to Figure 6 The display module 100 further includes an auxiliary member 80 disposed on the side of the extension portion 32 away from the first support portion 21, and the orthographic projection of the auxiliary member 80 on the first support portion 21 is located on the orthographic projection of the extension portion 32 on the first support portion 21.

Figure 8 , before the corrosive liquid intrudes into the junction of the flexible circuit board 50 and the display panel 10, it must first pass through the extension part 32 and the auxiliary part 80, thereby further increasing the length of the corrosive liquid intrusion path, further reducing the risk of metal circuit corrosion on the display panel 10, and improving the problem of metal circuit corrosion and poor functionality of the display module 100 during sweat or salt spray tests. In the drawings of the present application, the intrusion path of the corrosive liquid is indicated by a dotted line with an arrow.
