Description

Technical Field

[0001] This invention relates to the field of flexible display technology. More specifically, it relates to a flexible display module and a display device. Background Technology

[0002] Due to the requirements of driving circuits and manufacturing processes, existing displays have a non-display area around the display area for connecting driving circuits, etc. In the manufacturing process of OLED (Organic Light-Emitting Diode) display panels, the technology of bending the portion of the display panel near the bottom bezel towards its backlight side can significantly shorten the bezel width, becoming the current mainstream bending technology. This technology requires bending the pad area to the back of the display panel to reduce the bezel width. During bending, the bent area requires thinning treatments such as removing the back film, which makes the bent area of ​​the display panel increasingly fragile and prone to cracking. During the assembly process, after the flexible printed circuit board (FPC) connecting the main unit is plugged into the connector on the printed circuit board (PCB) of the display panel (which serves as the main circuit board), the FPC sags under the influence of gravity and the pressure of the entire assembly, contacting the bent area of ​​the display panel. After prolonged operation, this contact area is prone to cracking. Summary of the Invention

[0003] The purpose of this invention is to provide a flexible display module and display device, wherein the bending area of ​​the flexible display panel in the flexible display module is not easily in contact with the connecting flexible circuit board, thereby avoiding the problem of bending area breakage due to long-term contact and friction between the bending area and the flexible circuit board.

[0006] A cover plate is attached to the light-emitting side surface of the flexible display panel. The cover plate includes a main area and an extension area. The orthographic projection of the main area on the flexible display panel coincides with the flexible display panel, and the extension area is located outside the main area.

[0015] Optionally, the length of the first support member in the second direction is greater than or equal to the length of the flexible circuit board in the second direction plus 2mm, so that the first support member completely covers the flexible circuit board in the second direction, where the second direction is the direction in which the bending axis of the bending area extends.

[0016] Optionally, the length of the first support member in the third direction is less than the minimum distance from the edge of the cover plate to the side surface of the bending area away from the center of the flexible display panel in the third direction, so that there is a gap between the first support member and the bending area, wherein the third direction is a direction perpendicular to the bending axis of the bending area in a plane parallel to the flexible display panel.

[0017] Optionally, the first support component includes a boss disposed on the side surface of the cover plate near the flexible display panel, and an elastic layer attached to the side surface of the boss away from the cover plate, the elastic layer being attached to the side surface of the flexible circuit board near the flexible display panel.

Attached Figure Description

[0023] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Figure 1 The front view of the display module of the present invention is shown.

[0025] Figure 2 A partial cross-sectional view of an embodiment of the display module of the present invention is shown.

[0026] Figure 3 A partial cross-sectional view of another embodiment of the display module of the present invention is shown.

[0027] Figure 4 A cross-sectional view of the second support member of the present invention is shown. Detailed Implementation

[0028] To more clearly illustrate the present invention, the following description, in conjunction with preferred embodiments and accompanying drawings, further explains the invention. Similar components in the drawings are indicated by the same reference numerals. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of the present invention.

[0029] As consumers' demands for electronic products increase, OLED (Organic Light-Emitting Diode) flexible screens have emerged. In the manufacturing process of flexible screens, the technique of bending the portion of the display panel near the bottom bezel towards the backlight side has gradually replaced the COF (Chip On Film) bending technique, becoming the mainstream bending technology due to its ability to significantly shorten the bezel width. This technique requires bending the bonding area to the back of the display panel to reduce the bezel width. During bending, thinning processes such as back film removal are required in the bending area, which makes the pad bending area of ​​the flexible display panel increasingly fragile and prone to cracking.

[0030] In medium to large-sized foldable screen electronic products, such as foldable phones, foldable tablets, or rollable tablets, one end of a flexible circuit board connects to the display screen, and the other end connects to the main circuit board. This flexible circuit board connects the display screen to the main circuit board. Under the influence of gravity and the pressure applied by the device, this flexible circuit board may sag, causing contact friction between the flexible circuit board and the bending area of ​​the flexible display panel. After prolonged use, this can easily lead to breakage of the metal wires within the bending area, resulting in abnormal display problems.

[0031] To address the aforementioned issues, this disclosure provides a flexible display module and display device. By supporting the flexible circuit board, a certain gap is formed between the flexible circuit board and the bending area of ​​the flexible display panel, preventing the flexible circuit board from contacting the bending area during use. This avoids the bending area being subjected to external forces, thereby solving problems such as bending area breakage.

[0032] The following is combined Figures 1-4 The flexible display module provided in this embodiment is described below. The flexible display module in this embodiment includes a flexible display panel 10, a cover plate 20, a flexible circuit board 30, a first support component 40, and a second support component 50.

[0033] like Figure 1 and Figure 2As shown, the flexible display panel 10 provided in this embodiment of the present disclosure has a display area A and a peripheral area disposed around the display area A. The peripheral area is used for routing traces, such as gate driving circuits.

[0034] The display area A contains multiple display pixels, such as multiple display pixels arranged in a matrix. Each display pixel contains a pixel circuit and an OLED light-emitting device connected to the pixel circuit. The pixel circuit can drive the light-emitting device to emit light. In this case, the OLEDs in the multiple display pixels can emit at least three primary colors of light, such as red (R), green (G), and blue (B).

[0035] In some embodiments, the display area of ​​the flexible display panel 10 includes four sides, such as a first side A1, a second side A2 adjacent to the first side A1, a third side A3 opposite to the second side A2, and a fourth side A4 opposite to the first side A1.

[0036] The surrounding area can be further divided into a binding area S1 and a bending area S2, with the bending area S2 used to connect the binding area S1 and the display area A.

[0037] In some embodiments, both the binding area S1 and the bending area S2 are located on one side of the display area A, for example... Figure 1 As shown, both the bonding area S1 and the bending area S2 are located on the first side A1 of the display area A. For example, taking the flexible display panel 10 as an example of its application in a display device, the first side A1 can be the bottom side. In addition to the aforementioned display area A and peripheral area, the flexible display panel 10 also includes a polarizing film layer 11 stacked on the light-emitting side of the flexible display panel 10, a back film 12 disposed on the backlight side of the flexible display panel 10, and may also include other film layers such as a heat dissipation film composed of mesh adhesive and copper foil disposed on the side of the back film 12 away from the flexible display panel 10. The light-emitting side of the flexible display panel 10 is, for example, a... Figure 2 The lower side of the flexible display panel 10 shown, the backlight side of the flexible display panel 10, is, for example, Figure 2 The upper side of the flexible display panel 10 shown.

[0038] The bonding area S1 of the flexible display panel 10 is bent to the backlight side of the flexible display panel 10 through the bending area S2 and attached to the backlight side of the flexible display panel 10. Figure 2 In the structure shown, which includes a back film 12 and other film layers such as a heat dissipation film, the bonding area S1 is located on the side of the back film 12 away from the flexible display panel 10, specifically on the surface of the other film layers such as the heat dissipation film away from the flexible display panel 10. The bending area S2 connects the bonding area S1 and the display area A.

[0039] The bonding area S1 is equipped with a driver chip 13, and the bonding area S1 is connected to the driver flexible circuit board 14. The driver flexible circuit board 14 is connected to the circuit board 15. One end of the adapter flexible circuit board 30 is connected to the circuit board 15 through a connector.

[0040] In one example, display area A may also include multiple data lines (DL) and multiple gate lines (GL). Pixel circuits of display pixels located in the same row can be electrically connected to the same gate line. Pixel circuits of display pixels located in the same column can be electrically connected to the same data line. When a gate signal transmitted through a gate line selects a pixel circuit, a data signal can be written to the pixel circuit through the data line. In this way, the pixel circuit can drive the OLED light-emitting device electrically connected to the pixel circuit to emit light, thereby realizing the display image of the display module. To provide data signals and gate signals, the display module includes a driver chip 13 and a driver flexible circuit board 14, wherein the driver flexible circuit board 14 is used to connect the circuit board 15 to the flexible display panel 10. The circuit board 15 can provide gate signals to the pixel circuits through the driver flexible circuit board 14. Additionally, under the control of the circuit board 15, the driver chip 13 can provide data signals to the pixel circuits.

[0041] The cover plate 20 is attached to the light-emitting side surface of the flexible display panel 10. As an optional implementation, the cover plate 20 is adhered to the polarizing film layer 11 via an optical adhesive layer. The cover plate 20 provides protection for the display module and effectively improves the display effect. The cover plate 20 includes a main area and an extension area. The orthographic projection of the main area onto the flexible display panel 10 coincides with the flexible display panel 10. The extension area is located outside the main area, specifically in a third direction perpendicular to the bending axis of the bending area S2 within a plane parallel to the flexible display panel 10. Figure 1 and Figure 2 In the X direction shown, the length of the cover plate 20 is greater than the length of the flexible display panel 10, forming an extension area. That is, in the third direction (X direction), the edge of the cover plate 20 is further away from the center of the flexible display panel 10 than the edge of the bending area S2, and the flexible display panel 10 is completely covered by the cover plate 20.

[0042] One end of the first support member 40 is disposed on the side surface of the extension area of ​​the cover plate 20 near the flexible display panel 10, that is, the first support member 40 is disposed near the edge of the cover plate 20 at that location, and the other end of the first support member 40 is attached to the side surface of the adapter flexible circuit board 30 near the flexible display panel 10. In other words, the first support member 40 is located between the adapter flexible circuit board 30 and the cover plate 20, and is in contact and attached to both.

[0043] One end of the second support member 50 is attached to the surface of the bonding area S1 on the side away from the flexible display panel 10 (display area A), and the other end is attached to the surface of the adapter flexible circuit board 30 on the side close to the flexible display panel 10. That is, the second support member 50 is located between the adapter flexible circuit board 30 and the bonding area S1 of the flexible display panel 10, and is in contact with both. It is understood that, since the surface of the bonding area S1 is also connected to the driving flexible circuit board 14, the second support member 50 can extend to a portion of the surface of the driving flexible circuit board 14 on the side away from the flexible display panel 10 (display area A).

[0044] The first support member 40 and the second support member 50 jointly support the flexible circuit board 30 and are located on both sides of the bending area S2 in the third direction (X direction), respectively. This creates a gap between the flexible circuit board 30 above the bending area S2 and the bending area S2, preventing the flexible circuit board 30 from contacting the bending area S2 and thus avoiding the problem of metal trace breakage in the bending area S2. Since the two side surfaces of the second support member 50 are respectively attached to the flexible circuit board 30 and the bonding area S1, the distance of the aforementioned gap is approximately equal to the thickness of the second support member 50. Here, "equal" means equal within a certain tolerance range.

[0045] In one example, the surfaces of the first support member 40 and the second support member 50 that are attached to the flexible circuit board 30 are approximately flush, so that the portion of the flexible circuit board 30 located between the first support member 40 and the second support member 50 is approximately parallel to the flexible display panel 10, thereby preventing the flexible circuit board 30 from contacting the bending area S2.

[0046] In one example, such as Figure 2 As shown, the first support component 40 is configured as a three-layer structure, including a first elastic layer 41, a support layer 42 and a second elastic layer 43 that are sequentially bonded together. The first elastic layer 41 is bonded to the side surface of the flexible circuit board 30 that is close to the flexible display panel 10. The second elastic layer 43 is bonded to the side surface of the cover plate 20 that is close to the flexible display panel 10. The support layer 42 is located between the first elastic layer 41 and the second elastic layer 43 and is bonded to both of them.

[0047] Because the thickness of the first support member 40 is greater than that of the second support member 50, when the first support member 40 is made of an elastic material such as a single foam material, the supporting force provided by the first support member 40 is relatively small. Under the gravity and pressure of the flexible circuit board 30, the first support member 40 will experience a large amount of compressive deformation, causing the flexible circuit board 30 to come into contact with the bending area S2. Therefore, the first support member 40 is configured as a three-layer structure, with the middle layer being the support layer 42. The rigidity of the support layer 42 is much greater than that of the first elastic layer 41 and the second elastic layer 43, thereby improving the overall rigidity of the first support member 40. This ensures a small amount of deformation under prolonged pressure, thus improving its supporting performance. For example, the support layer 42 can be made of stainless steel (SUS) sheet, utilizing the fact that stainless steel sheet has a much greater rigidity than elastic materials such as foam materials to improve the supporting performance of the first support member 40. For example, in addition to foam materials, the first elastic layer 41 and the second elastic layer 43 can also be made of materials such as silicone gel and SPEA (Super Elastic Polymer Adhesive). In addition to stainless steel materials, the support layer 42 can also be made of materials such as PET (Polyethylene terephthalate), copper, and glass.

[0048] In one example, the density of the first elastic layer 41 is less than that of the second elastic layer 43, resulting in greater elasticity in the first elastic layer 41 and less elasticity in the second elastic layer 43. Since the first elastic layer 41 is bonded to the flexible circuit board 30, it can distribute the force exerted by the flexible circuit board 30 onto the support layer 42, and cause the second elastic layer 43 to undergo smaller deformation, thereby improving the support performance of the first support component 40. For example, the first elastic layer 41 is a first foam layer with a density greater than or equal to 0.4 g / cm³. 3 And less than 0.7 g / cm 3 For example, the density of the first foam layer can be 0.4 g / cm³. 3 0.45g / cm 3 0.5g / cm 3 0.6g / cm 3 Or 0.65g / cm 3 .

[0049] For example, the first elastic layer 41 is a first foam layer, and the second elastic layer 43 is a second foam layer. Both the first and second foam layers are double-sided foam with adhesive on both sides. The first foam layer is bonded to the flexible circuit board 30, and the second foam layer is bonded to the cover plate 20. At the same time, the first and second foam layers are bonded to the two side surfaces of the support layer 42, which can fix the flexible circuit board 30 and prevent the flexible circuit board 30 from vibrating significantly during use.

[0050] In one example, the density of the second foam layer is greater than or equal to 0.7 g / cm³. 3 For example, the density of the second foam layer can be 0.7 g / cm³. 3 0.8g / cm 3 0.85g / cm 3 0.9g / cm 3 Or 1.0g / cm 3 The length of the second foam layer in the first direction is greater than or equal to 1.7 mm, and the first direction is perpendicular to the flexible display panel 10. Figure 1 and Figure 2 In the Y direction, the length of the second foam layer in the first direction can also be called the height or thickness of the second foam layer. For example, the thickness of the second foam layer can be 1.7mm, 1.8mm, or 1.9mm. This ensures that the first support member 40 has sufficient support force, preventing the first support member 40 from deforming excessively when the force applied by the flexible circuit board 30 to the first support member 40 is large, thus avoiding contact between the flexible circuit board 30 and the bending area S2. The second support member 50 is, for example, made of a single layer of foam material. When the second support member 50 is attached between the flexible circuit board 30 and the bonding area S1, the length of the first support member 40 in the first direction (Y direction) (which can be called the height or thickness of the first support member 40) is slightly greater than the distance from the side surface of the flexible circuit board 30 near the flexible display panel 10 to the side surface of the cover plate 20 near the flexible display panel 10.

[0051] Understandably, both the first support member 40 and the second support member 50 will undergo a certain amount of compression deformation after being subjected to the force of the flexible circuit board 30, causing the flexible circuit board 30 to move toward the flexible display panel 10. Therefore, the thickness of the first support member 40 and the second support member 50 should be sufficient to ensure that the flexible circuit board 30 cannot contact the bending area S2 after compression deformation.

[0052] In one example, the length of the first support member 40 in the third direction (X direction) (which may be referred to as the length of the first support member 40) should be less than the minimum distance from the edge of the cover plate 20 to the side surface of the bending area S2 away from the center of the flexible display panel 10 in the third direction (X direction), so that there is a gap between the first support member 40 and the bending area S2, that is, in Figure 2 In the X direction, the length of the first support member 40 is less than the length from the bending area S2 to the right edge of the cover plate 20, so as to avoid the first support member 40 from contacting the bending area S2.

[0053] The length of the first support component 40 in the second direction is greater than or equal to the length of the flexible circuit board 30 in the second direction plus 2mm, where the second direction is the direction in which the bending axis of the bending zone S2 extends. Figure 1 and Figure 2 In the Z direction, the length of the first support member 40 in the second direction can also be called the width of the first support member 40. That is, the width of the first support member 40 is at least 2mm larger than the width of the flexible circuit board 30, so that the first support member 40 completely covers the flexible circuit board 30 in the second direction (Z direction). For example, after the first support member 40 is attached to the flexible circuit board 30, both sides of the first support member 40 in the second direction (Z direction) extend beyond the edge of the flexible circuit board 30, so that the flexible circuit board 30 is entirely located on the first support member 40 in the second direction (Z direction).

[0054] In one example, for example Figure 2 As shown, the bending surface of the bending area S2 near the first support member 40 in the third direction (X direction) is covered with a protective adhesive layer 16, such as MCL adhesive (Metal Cover Layer). The protective adhesive layer 16 attached to the outer surface of the bending area S2 can keep the bending area S2 in an arc shape and prevent the bending area S2 from deforming, which could lead to a break in the circuit wiring.

[0055] In one example, the back film 12 is removed from the bending surface of the bending zone S2 away from the first support member 40 in the third direction (X direction), that is, the back film 12 is not provided at the bending zone S2, thereby improving the bending performance of the bending zone S2.

[0056] In some examples, such as Figure 3As shown, the first support member 40 includes a boss 45 disposed on the side surface of the cover plate 20 near the flexible display panel 10, and an elastic layer 44, for example made of foam, attached to the side surface of the boss 45 away from the cover plate 20. The elastic layer 44 is attached to the side surface of the adapter flexible circuit board 30 near the flexible display panel 10. This type of first support member 40 is formed by the boss 45 and the elastic layer 44. The elastic layer 44 is, for example, double-sided foam with adhesive on both sides, with one side surface bonded to the top surface of the boss 45 and the other side surface bonded to the adapter flexible circuit board 30.

[0057] In one example, the boss 45 can be integrally formed with the cover plate 20. For example, when the cover plate 20 is thinned by grinding, the position of the boss 45 is not thinned, so that the final surface of the cover plate 20 has the boss 45 protruding.

[0058] In one example, such as Figure 4 As shown, the surface 51 of the second support member 50, which is attached to the bonding area S1, is recessed inward to form a clearance portion, so as to avoid and accommodate the device located in the bonding area S1, such as the driver chip 13. The surface 51 of the second support member 50 corresponds to the surface of the bonding area S1, so that after the second support member 50 is attached to the surface of the bonding area S1, the surface of the second support member 50 and the flexible circuit board 30 is approximately flat, ensuring the bonding effect between the second support member 50 and the flexible circuit board 30. The second support member 50 can be made of a foam material with a high density, such as a density greater than or equal to 0.9 g / cm³. 3 And less than or equal to 1.2 g / cm 3 Foam materials, for example, with a density of 0.9 g / cm³. 3 0.95g / cm 3 1.0g / cm 3 1.1g / cm 3 Or 1.2g / cm 3 This type of foam material has high rigidity and is not easily deformed under stress, thus providing good support for the flexible circuit board 30.
