Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a flexible display panel and an electronic device. Background Art

[0002] With the continuous development of display technology, various displays with different characteristics have emerged to meet different usage needs. The development trend of intelligence, portability and flexibility is one of the main development directions of current electronic devices. The most prominent advantage of flexible display technology over traditional flat-panel display technology is that it breaks through the inherent concept of the original two-dimensional display and expands the application field of display technology to more portable electronic devices. Users can fold or curl electronic devices with flexible display panels as needed to reduce the size of the electronic device and improve the portability of the electronic device.

[0003] Currently, before or after a foldable electronic device is folded inward or outward, the sizes of the hinge mechanism and the flexible display panel body cannot match each other, causing the hinge mechanism to squeeze or pull the flexible display panel body.

[0004] In summary, the existing flexible display panel and electronic device have the problem that the sizes of the hinge and the flexible display panel body cannot match each other. Therefore, it is necessary to provide a flexible display panel and an electronic device to improve this defect. Summary of the invention

In the drawings, units with similar structures are represented by the same reference numerals.

[0062] The present application is further described below in conjunction with the accompanying drawings and specific embodiments.

[0063] The embodiment of the present application provides a flexible display panel and an electronic device, wherein the electronic device includes the flexible display panel. In the embodiment of the present application, the electronic device may be a mobile terminal, such as a smart phone, a tablet computer, a laptop computer, etc., or a wearable terminal, such as a smart watch, a smart bracelet, smart glasses, an augmented reality device, etc., or a fixed terminal, such as a desktop computer, a television, etc.

[0065] like Figure 2 As shown, Figure 2 The flexible display panel provided in the embodiment of the present application is a cross-sectional schematic diagram in a flattened state, wherein the flexible display panel body 10 includes a flexible portion 11 and a first portion 12 and a second portion 13 connected to opposite ends of the flexible portion 11, and the flexible portion 11 is a portion of the flexible display panel body 10 that can be folded.

[0066] In the embodiment of the present application, the first support member 20 and the second support member 30 may be the first middle frame and the second middle frame of the flexible display panel, respectively, and the first middle frame and the second middle frame may be configured to carry the flexible display panel body 10. The first rear shell 70 is disposed on the side of the first support member 20 away from the flexible display panel body 10, and the second rear shell 80 is disposed on the side of the second support member 30 away from the flexible display panel body 10. The first support member 20 and the second support member 30 may each have a separate accommodation space, or the first support member 20 and the second support member 30 may form an accommodation space with the first rear shell 70 and the second rear shell 80, respectively, and the accommodation space may accommodate electronic components in the electronic device, such as a main board, a printed circuit board, and a battery, which are necessary electronic components for driving the flexible display panel 100.

[0067] In practical applications, the first support member 20 and the first middle frame can be two independent parts, and the first support member 20 can be a support plate, and the first support member 20 can be fixedly connected to the first middle frame by means of threaded connection, snap-fitting, etc., or can be slidably connected to the first middle frame, so that the first middle frame can approach or move away from the fixed bracket as the first support member 20 is driven by the first motion mechanism. The second support member 30 and the second middle frame can be two independent parts, and the second support member 30 can also be a support plate, and the second support member 30 can be fixedly connected to the second middle frame by means of threaded connection, snap-fitting, etc., or can be slidably connected to the second middle frame, so that the second middle frame can approach or move away from the fixed bracket as the second support member 30 is driven by the second motion structure.

[0068] The first portion 12 may be disposed on at least a portion of the front side of the first support member 20, and the first front frame 50 may be disposed on the front side of the first support member 20 and cover the outer edge of the first portion 12.

[0069] It should be noted that the flexible display panel 100 may have at least one rotation axis for the folded flexible display panel 100. Hereinafter, the first direction x represents a direction perpendicular to the rotation axis, the second direction y represents a direction parallel to the rotation axis, and the third direction z represents a direction perpendicular to the plane where the first direction x and the second direction y are located. The display surface of the flexible display panel 100 in the flattened state may be defined by the first direction x and the second direction y.

[0071] like Figure 2 as well as Figure 4 As shown in Figure 4c, in this article, the flattened state may refer to a state in which the flexible display panel and the electronic device are fully unfolded, and an angle of about 180 degrees is formed between the front sides of the first support member 20 and the second support member 30, so that at least a portion of the first part 12 and the second part 13 of the flexible display panel body 10 can be in the same plane with the flexible part 11, and the flexible part 11 is in a flat state.

[0072] In practical applications, the mode in which the flexible display panel is in a flat state can be used as a tablet mode of the electronic device, so that the electronic device can obtain a maximum display area.

[0073] Figure 3 3a and Figure 4 4a are schematic diagrams of the flexible display panel in the first fully folded state. Herein, the first fully folded state may refer to a state in which the flexible display panel and the electronic device are completely folded inward and an angle of about 0 degrees is formed between the front sides of the first support member 20 and the second support member 30, so that the first portion 12 and the second portion 13 of the flexible display panel body 10 can face each other.

[0074] In practical applications, the first fully folded state can be used as a portable mode of the electronic device, and the flexible display panel body 10 can be surrounded by the first support member 20, the second support member 30 and other structures to prevent the flexible display panel body 10 from being damaged.

[0075] Figure 4 4b is a schematic diagram of the flexible display panel in the first transitional folding state. Herein, the first transitional folding state may refer to a state in which the flexible display panel and the electronic device are between the first fully folded state and the flat state. When the flexible display panel and the electronic device are in the first fully folded state or the first transitional folding state, the flexible portion 11 is in the first bent state.

[0076] Figure 3 3b and Figure 4 4e is a schematic diagram of the flexible display panel in the second fully folded state. Herein, the second fully folded state may refer to a state in which the flexible display panel and the electronic device are completely folded outward and an angle of about 360 degrees is formed between the front sides of the first support member 20 and the second support member 30, so that the first portion 12 and the second portion 13 of the flexible display panel body 10 can be away from each other, and the first rear shell 70 and the second rear shell 80 can face each other.

[0077] In practical applications, the second fully folded state mode can be used as a mobile phone mode of the electronic device, and either the first part 12 or the second part 13 can be used to display the picture, thereby improving the convenience of using and holding the flexible display panel and the electronic device.
