Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application

[0026] Please refer to Figure 1 , an electronic device 1000 is provided in an embodiment of this application for displaying patterns. The electronic device 1000 may include a home television, a public display, a mobile phone, a watch, etc. The electronic device 1000 may include a display control module 200 and a flexible display device 100. The display control module 200 is electrically connected or communicatively connected to the flexible display device 100 so that the display control module 200 can control the flexible display device 100 to display patterns. In this embodiment, the display may include the flexible display device 100, and the form of the flexible display device 100 can be adjusted according to user needs, expanding the application scope of the electronic device 1000

[0027] Please refer to Figure 1 , in this embodiment, the flexible display device 100 may include a transparent flexible substrate 30 and a light source module 10. The light source module 10 is used for emitting light and forming an image. The light source module 10 may include a transparent flexible circuit board 11 and a plurality of LED light sources 12. The transparent flexible circuit board 11 is disposed on one side of the transparent flexible substrate 30, and the plurality of LED light sources 12 are arranged in an array on the side of the transparent flexible circuit board 11 facing away from the transparent flexible substrate 30. The display control module 200 is electrically connected to the transparent flexible circuit board 11 so that the plurality of LED light sources 12 emit light under the control of the display control module 200 and cooperate with each other to form an image. In this embodiment, the transparent flexible circuit board 11 can be deformed so that the transparent flexible circuit board 11 and the light source module 10 can adapt to other structures, making the application scope of the light source module 10 wider

[0028] Please refer to Figure 1 and Figure 2In this embodiment, the flexible display device 100 may further include a transparent flexible sealing member 20, wherein the transparent flexible sealing member 20 is an integrally formed structure, for example, it can be formed by processes such as glue filling, 3D printing, and compression molding. In this embodiment, the transparent flexible sealing member 20 is arranged on the side of the light source module 10 away from the transparent flexible substrate 30, so that the transparent flexible sealing member 20 and the transparent flexible substrate 30 jointly clamp the transparent flexible circuit board 11 to protect the transparent flexible circuit board 11 and the LED light source 12. In this embodiment, the transparent flexible sealing member 20 includes an integrally formed covering portion 22 and a plurality of lens portions 21 arranged at intervals. The arrangement of the plurality of lens portions 21 is arranged according to the array arrangement of the plurality of LED light sources 12, and each lens portion 21 can at least cover one LED light source 12, and the light emitted by the LED light source 12 can be emitted after the optical action of the lens portion 21. The lens portion 21 has a specified optical focal length, and the lens portions 21 with different optical focal lengths have different optical effects on light. As an example, the lens portion 21 with a positive optical focal length has a converging effect on light so that the light is brighter after being emitted, so that the pattern formed by the multiple LED light sources 12 is clearer, which is convenient for the audience located directly in front of the flexible display device 100 to watch. As another example, the lens portion 21 with a negative optical focal length has a diverging effect on light, which can increase the divergence angle of light, for example, so that the divergence angle of the image is expanded to 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, etc., so that the audience located in the positive side direction of the flexible display device 100 can also watch the content in the flexible display device 100, so that the flexible display device 100 can meet the viewing needs of more audiences, and the setting of the flexible display device 100 and the display device can be reduced.

[0029] See also Figure 1 and Figure 2 In this embodiment, the covering portion 22 is connected between the multiple lens portions 21 to form an integrated structure. The covering portion 22 covers the transparent flexible circuit board 11 to protect the transparent flexible circuit board 11, thereby extending the service life of the transparent flexible circuit board 11 and the flexible display device 100. In this embodiment, the covering portion 22 is a transparent structure, and at least part of the light emitted by the LED light source 12 can be emitted through the covering portion 22, so that the light between two adjacent LED light sources 12 can be continuous and gently transitioned, so that the image composed of multiple LEDs is continuous, and the display effect of the flexible display device 100 is improved. In other embodiments, the covering portion 22 can be set to an opaque structure according to the specific image harness requirements. For example, the transparent flexible sealing member 20 formed by the glue injection process can add other colloids during the curing process of the covering portion 22 to make the covering portion 22 opaque, so that the image composed of multiple LEDs is composed of point-shaped light spots, which improves the eye-catching degree of the image.

[0030] In summary, the flexible display device 100 in this embodiment includes a transparent flexible substrate 30, a light source module 10, and a transparent flexible encapsulant 20 covering the light source module 10. The transparent flexible encapsulant 20 is transparent and has the ability to deform. The transparent flexible substrate 30 is transparent and has the ability to deform. The transparent flexible circuit board 11 of the light source module 10 is transparent and has the ability to deform, so that the flexible display device 100 is a flexible transparent display screen, which can improve the display effect of the flexible display device 100, provide a better experience for the audience, and enable the form of the flexible display device 100 to be adjusted according to user needs, expanding the application range of the electronic device 1000. The transparent flexible encapsulant 20 includes an integrally formed covering portion 22 and a lens portion 21. The lens portion 21 covers a plurality of LED light sources 12 on the light source module 10. The light emitted by the LED light sources 12 can achieve the required display effect after being refracted optically by the lens portion 21. For example, when the lens portion 21 is used to focus light, its focusing process can make the image brighter and clearer. For another example, when the lens portion 21 is used to diverge light, the light emitted by the LED light sources 12 can be diverged by the lens portion 21 to increase the divergence angle of the light and the image, so that the flexible display device 100 can meet the needs of being viewed by more people, thereby improving the display effect of the flexible display device 100 and expanding the applicable range of the flexible display device 100.

[0031] Please refer to Figure 1 and Figure 2 , in this embodiment, a plurality of LED light sources 12 are arranged in an array. Specifically, a plurality of LED light sources 12 are respectively arranged along a first direction and a second direction, and the first direction intersects the second direction. In some other embodiments, a plurality of LED light sources 12 are arranged in a circular array. In this embodiment, the first direction and the second direction are perpendicularly arranged so that a plurality of LED light sources 12 are arranged in a rectangular array, that is, the first direction is the column direction and the second direction is the row direction. A plurality of LED light sources 12 are arranged in multiple rows and multiple columns. A plurality of LED light sources 12 in each column are arranged at intervals along the first direction in sequence, and a plurality of LED light sources 12 in each row are arranged at intervals along the second direction in sequence. In other embodiments, the first direction and the second direction may intersect and not be perpendicular.

[0032] In this embodiment, the number of lens portions 21 is the same as the number of LED light sources 12. The multiple lens portions 21 are arranged according to the arrangement of the multiple LED light sources 12, that is, the multiple lens portions 21 are also arranged along the first direction and the second direction respectively to form a rectangular array, and form multiple rows and multiple columns. The number of lens portions 21 in each row is the same as the number of LED light sources 12 in each row, and the number of lens portions 21 in each column is the same as the number of LED light sources 12 in each column. The multiple lens portions 21 are arranged in one-to-one correspondence with the multiple LED light sources 12, and each lens portion 21 covers a corresponding one of the LED light sources 12. The light emitted by the LED light source 12 can be emitted through the focusing or diverging effect of the corresponding one of the lens portions 21.

[0033] In some other embodiments, the lens portion 21 is a columnar lens portion 21. The number of the columnar lens portions 21 is the same as the number of rows of the LED light sources 12. The multiple lens portions 21 are arranged at intervals along the first direction. The multiple lens portions 21 are in one-to-one correspondence with the multiple rows of LED light sources 12. Each lens portion 21 can cover multiple LED light sources 12 in the corresponding row, that is, each columnar lens portion 21 can cover multiple LED light sources arranged along the second direction. The light emitted by the multiple LED light sources 12 in each row can be emitted through the focusing or diverging effect of the corresponding one of the lens portions 21.

[0034] In some other embodiments, the lens portion 21 is a columnar lens portion 21. The number of the columnar lens portions 21 is the same as the number of columns of the LED light sources 12. The multiple lens portions 21 are arranged at intervals along the second direction. The multiple lens portions 21 are in one-to-one correspondence with the multiple columns of LED light sources 12. Each lens portion 21 can cover multiple LED light sources 12 in the corresponding column, that is, each columnar lens portion 21 can cover multiple LED light sources arranged along the first direction. The light emitted by the multiple LED light sources 12 in each column can be emitted through the focusing or diverging effect of the corresponding one of the lens portions 21.

[0035] In this embodiment, the multiple lens portions 21 are arranged in an array. The outer contour of the multiple lens portions 21 is slightly smaller than the outer contour of the transparent flexible encapsulant 20. The optical power of the multiple lens portions 21 located at the central position of the transparent flexible encapsulant 20 is positive optical power, and the optical power of the multiple lens portions 21 located at the edge portion of the transparent flexible encapsulant 20 is negative optical power, so as to ensure the brightness of the image and the viewing angle of the flexible display device 100. In some other embodiments, the optical power of each lens portion 21 can be selected according to the display requirements or the type of the image.

[0036] Please refer to Figure 2, in this embodiment, the LED light source 12 is embedded in a corresponding lens part 21. The embedded structure makes the relative position state of the transparent flexible sealing member 20 and the light source module 10 relatively stable. The covering part 22 fits on the surface of the transparent flexible circuit board 11, making the connection relationship of the relative position state between the transparent flexible sealing member 20 and the light source module 10 relatively stable. Specifically, in this embodiment, each lens part 21 is provided with an avoidance groove 211 on the side facing the transparent flexible circuit board 11, and a corresponding LED light source 12 of each lens part 21 is embedded in the avoidance groove 211.

[0037] In this embodiment, the side of the avoidance groove of each lens part 21 facing the transparent flexible circuit board 11 defines a first lens surface 212, and most of the light rays emitted by a corresponding LED light source 12 of the lens part 21 can be conducted to the first lens surface 212. The side of the lens part 21 facing away from the transparent flexible circuit board 11 defines a second lens surface 213. The second lens surface 213 is directly opposite to the first lens surface 212, and the light rays pass through the first lens surface 212 and the second lens surface 213 in sequence and then exit the lens part 21. In this embodiment, the area of the second lens surface 213 can be set to be larger than the area of the first lens surface 212 so that more light rays can exit through the second lens surface 213. In this embodiment, the shapes of the first lens surface 212 and the second lens surface 213 together determine the optical power of the lens part 21 described above.

[0038] Please refer to Figure 2 , in this embodiment, the side of the LED light source 12 facing away from the transparent flexible circuit board 11 is a plane. Due to differences in the production process of the transparent flexible sealing member 20, the shape of the avoidance groove 211 will vary, and the shapes of the first lens surface 212 and the second lens surface 213 will be adaptively adjusted according to different production processes.

[0039] Please refer to Figure 2 and Figure 3, as a first example, the liquid raw material of the transparent flexible encapsulant 20 is directly potted on the transparent flexible circuit board 11 and the plurality of LED light sources 12. The shape of the avoidance groove 211 of each lens part 21 coincides with the shape of a corresponding LED light source 12. The lens part 21 is in a shape that wraps around the outer surface of the LED light source 12. The inner wall of the avoidance groove 211 fits the outer surface of the LED light source 12. One side surface of the LED light source 12 facing away from the transparent flexible circuit board 11 is a flat surface. Therefore, the first lens surface 212 is a flat surface. In the first example, the second lens surface 213 can be set as a convex curved surface, that is, the second lens surface 213 bends along the direction away from the first lens surface 212, so that the optical power of the lens part 21 is a positive optical power. The structure between the first lens surface 212 and the second lens surface 213 is similar to that of a convex lens. Therefore, the lens part 21 has a focusing effect on the light emitted by the LED light source 12. In the first example, the second lens surface 213 can be set as a concave curved surface, that is, the second lens surface 213 bends along the direction close to the first lens surface 212, so that the optical power of the lens part 21 is a negative optical power. The structure between the first lens surface 212 and the second lens surface 213 is similar to that of a concave lens. Therefore, the lens part 21 has a diverging effect on the light emitted by the LED light source 12.

[0040] Please refer to Figure 4 and Figure 5 , as a second example, the transparent flexible encapsulant 20 is a structure formed by injection molding, die molding or turning and milling. Then, the inner wall of the avoidance groove 211 and the outer surface of the LED light source 12 can be arranged at intervals, that is, the size of the avoidance groove 211 of the lens part 21 can be set to be larger than the size of the corresponding LED light source 12, so as to facilitate the assembly of the transparent flexible encapsulant 20 and the light source module 10. In this example, the second lens surface 213 is a flat surface, and the second lens surface 213 is smoothly connected to the side of the covering part 22 facing away from the transparent flexible circuit board 11, so that the side of the transparent flexible encapsulant 20 facing away from the transparent flexible circuit board 11 is a flat surface, so as to avoid excessive dust adhering to the flexible display device 100 and facilitate the cleaning of the surface of the flexible display device 100. In the first example, the first lens surface 212 can be set as a convex curved surface, that is, the first lens surface 212 bends along the direction away from the second lens surface 213, so that the optical power of the lens part 21 is a positive optical power. The structure between the first lens surface 212 and the second lens surface 213 is similar to that of a convex lens. Therefore, the lens part 21 has a focusing effect on the light emitted by the LED light source 12. In the second example, the first lens surface 212 can be set as a concave curved surface, that is, the first lens surface 212 bends along the direction close to the second lens surface 213, so that the optical power of the lens part 21 is a negative optical power. The structure between the first lens surface 212 and the second lens surface 213 is similar to that of a concave lens. Therefore, the lens part 21 has a diverging effect on the light emitted by the LED light source 12.

[0041] In the embodiment described above where a lens portion 21 covers a plurality of LED light sources 12, the arrangement of the avoidance groove 211 and the first lens surface 212 and the second lens surface 213 can refer to the arrangement described above, and no further elaboration will be provided in this embodiment.

[0042] Please refer to Figure 6 , in this embodiment, both the covering portion 22 and the lens portion 21 can also be transparent structures. In this embodiment, the flexible display device 100 can further include a light-shielding layer 40. The light-shielding layer 40 covers the side of the covering portion 22 facing away from the transparent flexible circuit board 11 to prevent light from being emitted through the covering portion 22. The light-shielding layer 40 exposes a plurality of lens portions 21 so that light can be emitted through the lens portions 21. With the arrangement in this embodiment, the image displayed by the flexible display device 100 can be made to resemble a pattern formed by light spots, enhancing the attractiveness of the image.

[0043] This embodiment provides a flexible display device 100. The flexible display device 100 includes a transparent flexible substrate 30, a light source module 10, and a transparent flexible encapsulant 20 covering the light source module 10. The transparent flexible encapsulant 20 is transparent and has the ability to deform. The transparent flexible substrate 30 is transparent and has the ability to deform. The transparent flexible circuit board 11 of the light source module 10 is transparent and has the ability to deform, so that the flexible display device 100 is a flexible transparent display screen, which can improve the display effect of the flexible display device 100, provide a better experience for the audience, and enable the form of the flexible display device 100 to be adjusted according to user needs, expanding the application range of the electronic device 1000. The transparent flexible encapsulant 20 includes an integrally formed covering portion 22 and a lens portion 21. The lens portion 21 covers a plurality of LED light sources 12 on the light source module 10. The light emitted by the LED light sources 12 can achieve the required display effect after passing through the optical refraction of the lens portion 21. For example, when the lens portion 21 is used to focus light, its focusing process can make the image brighter and clearer. For another example, when the lens portion 21 is used to diverge light, the light emitted by the LED light sources 12 can be diverged by the lens portion 21 to increase the divergence angle of the light and the image, enabling the flexible display device 100 to meet the needs of being viewed by a larger number of people, thereby improving the display effect of the flexible display device 100 and expanding the applicable range of the flexible display device 100.
