Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to OLED display devices and electronic devices. Background Technology

[0002] In recent years, flexible OLED (Organic Light-Emitting Diode) displays have become increasingly widely used to improve the appearance and display effect of monitors. OLEDs are active light-emitting devices with a sandwich structure consisting of multiple organic layers and electrodes on both sides. Currently, AMOLED (Active-matrix organic light-emitting diode) based displays have been commercialized in fields such as smartphones, watches, and laptops.

[0003] Currently, due to the need for narrow bezels in OLED electronic products, the distance between the four corners of the display panel and the four corners of the cover glass is very short. When the display module is in its modular state, the four corners are easily damaged by accidental pressing or bumps from workers, resulting in black spots. Even when the product is in its entirety, slipping can easily cause the four corners to crack, which is usually a major factor in product damage. Therefore, improving the impact resistance (pressing, bumping, dropping) of the four corners of the display module is particularly important. Utility Model Content

Together with the fixed frame 120, it protects the display module 110, effectively preventing the display module 110 from being damaged by drops, and improving the drop resistance of the display device 100. Attached Figure Description

[0016] Figure 1 This is a cross-sectional schematic diagram of the OLED display device disclosed in the first preferred embodiment of the present invention; Figure 2 This is a plan view of the OLED display device disclosed in the first preferred embodiment of the present invention. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, the first preferred embodiment of the present invention discloses an OLED display device 100, which includes a display module 110, a fixed frame 120 and a flexible buffer 130.

[0019] The aforementioned display module 110 includes a display panel 111 and a cover plate 112, wherein the cover plate 112 is disposed on the light-emitting side of the display panel 111.

[0020] The aforementioned display panel 111 serves as the light source for the module, responsible for generating image signals. In this embodiment, the aforementioned display panel 111 is an OLED display panel, in which each pixel is self-emissive, eliminating the need for a backlight layer. A cover plate 112 covers the light-emitting surface of the display panel 111, and the display panel 111 and the cover plate 112 are bonded together using an optical adhesive (OCA) full lamination process.

[0021] Overall, the aforementioned fixing frame 120 has a ring-shaped structure, which surrounds the periphery of the display module 110. The fixing frame 120 is used to support the display module and includes a base plate 121 and a middle frame 122. Specifically, the base plate 121 is located at the bottom of the display module 110 and is used to support the display module 110. The middle frame 122 is located on the side of the display module 110 and is used to restrict the lateral movement of the display module 110.

[0022] The aforementioned fixed frame 120 is a ring structure, which completely surrounds the display module 110, reserving assembly space for the display module 110. It also forms a mechanical support skeleton ring structure to enhance overall torsional strength.

[0023] The base plate 121 and middle frame 122 of the aforementioned fixed frame 120 have an "L"-shaped cross-section. The base plate 121 extends horizontally and the middle frame 122 extends vertically to form a continuous right-angle support. This structure can improve bending stiffness and disperse the impact force of screen drop to the entire frame. Specifically, the base plate 121 of the aforementioned fixed frame 120 is located directly below the aforementioned display module 110, so that vertical load-bearing can disperse the impact force. The middle frame 122 of the aforementioned fixed frame 120 is located at the four edges of the aforementioned display module 110, mainly for lateral restraint to prevent displacement / vibration deviation. The base plate 121 and middle frame 122 of the aforementioned fixed frame 120 can be formed by laser welding or integral die casting, and stress relief treatment is performed at the joint.

[0024] The flexible buffer 130 is located between the fixed frame 120 and the display module 110, and fits a portion of the upper surface of the cover plate 112 and a portion of the lower surface of the display module 110. In other words, the flexible buffer 130 wraps around the edge portion of the display module 110 near the side.

[0025] Specifically, the flexible buffer 130 is located between the fixed frame 120 and the display panel 111 and cover plate 112 of the display module 110. The flexible buffer 130 wraps around the edge near the upper surface of the cover plate 112, with a coverage width of 0.5 mm to 1.2 mm. This flexible buffer 130 can disperse the peak stress of the drop impact when the OLED display device 100 is dropped. The flexible buffer 130 also wraps around the edge near the lower surface of the cover plate 112, with a coverage width of 0.8 mm to 1.5 mm. This flexible buffer 130 can suppress micro-vibrations caused by assembly tolerances. Simultaneously, the flexible buffer 130 wraps around the side of the cover plate 112, and this flexible buffer 130 can counteract lateral shear forces.

[0026] The aforementioned flexible buffer 130, through three-dimensional wrapping, converts impact energy into material deformation energy, achieving an energy absorption rate of up to 85%. This prevents the display module 110 from rigidly contacting the fixed frame 120, reducing the probability of the display module 110 breaking. It should be noted that if the display module 110 is a curved display module, the coverage width of the flexible buffer 130 covering the edges of the upper and lower surfaces of the cover plate 112 can reach 1.8 mm. The flexible buffer 130 can be an elastic structure such as modified silicone rubber, polyurethane microfoam, or liquid crystal elastomer.

[0027] More specifically, the flexible buffer 130 has an "I"-shaped cross-section. This "I"-shaped flexible buffer 130 has a first groove structure 131 and a second groove structure 132 located on the other side of the first groove structure 131. The side of the cover plate 112 is fitted into the first groove structure 131. The first groove structure 131 is used to accommodate and fix one end of the cover plate of the display module 110; while the second groove structure 132 is used to fixably connect to the middle frame 122 of the fixing frame 120, thus achieving a fixed connection between the display module 110 and the fixing frame 120.

[0028] In this embodiment, the middle frame 122 has a third groove structure 1221, which is fitted into and fixedly connected to the lower end of the flexible buffer 130, thereby preventing the flexible buffer 130 from falling off the middle frame 122. Combination Figure 1 and Figure 2 As shown, in the first embodiment of this method, the fixed frame 120 has a straight edge area A and a corner area B, and the flexible buffer 130 is located on the inner side of the corner area B of the fixed frame 120. The straight edge area A of the fixed frame 120 corresponds to the straight edge of the display module 110, and the corner area B of the fixed frame 120 corresponds to the corner of the display module 110. The flexible buffer 130 is located on the inner side of the corner area of ​​the fixed frame.

[0029] Combination Figure 1 and Figure 2 As shown, in the second embodiment of this embodiment, in addition to the flexible buffer 130 being located on the inner side of the corner area of ​​the fixed frame, the flexible buffer 130 is located on the inner side of the straight edge area A of the fixed frame 120.

[0030] The flexible buffer 130 is fixed to the fixed frame 120 by an adhesive structure. More specifically, corresponding to the position of the flexible buffer 130, the fixed frame 120 includes a second groove structure 123 for limiting the flexible buffer 130, and the flexible buffer 130 includes a second protrusion structure 133, and the flexible buffer 130 is interlocked with the second groove structure 123 of the fixed frame through the second protrusion structure 133.

[0031] The OLED display device 100 can withstand external impacts by setting the aforementioned flexible buffer 130, and together with the aforementioned fixed frame 120, it protects the display module 110, effectively preventing the display module 110 from being damaged by drops, and improving the drop resistance of the display device 100.

[0032] In another embodiment of the present invention, an electronic device is provided, which includes the OLED display device described above. The OLED display device 100 can withstand external impact by setting the flexible buffer 130, and together with the fixed frame 120, it protects the display module 110, effectively preventing the display module 110 from being damaged by drops, and improving the drop resistance of the display device 100.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
