Figure 2 for Figure 1 A partially enlarged exploded schematic diagram of the organic light-emitting diode display device 10. Figure 3 for Figure 2 A partially enlarged schematic diagram of the organic light-emitting diode panel module 12 and the flexible circuit board 14 from another viewpoint. Figure 1 , Figure 2 as well as Figure 3 As shown, the organic light-emitting diode display device 10 of this utility model may include an organic light-emitting diode panel module 12 and at least one flexible circuit board 14 (in Figure 2three, but not limited to, the number of circuit boards is configured according to the actual manufacturing requirements of the organic light-emitting diode display device 10, and the decorative plate structure 16. The flexible circuit board 14 can preferably adopt a Chip On Film (COF) process (but not limited to) to achieve the flexible bending function of the circuit board, and is electrically connected to the organic light-emitting panel module 12 and extends outward from the bottom edge E of the organic light-emitting diode panel module 12 in the first direction D1, thereby being used to control the image display of the organic light-emitting panel module 12 (the related description of the circuit board process and the circuit control light-emitting design is commonly seen in the prior art, and will not be repeated here), wherein the organic light-emitting panel module 12 is shown by Figure 3 It can be seen that the first direction D1 is perpendicular to the normal direction N of the organic light-emitting diode panel module 12, preferably, the flexible circuit board 14 can be bent from the organic light-emitting panel module 12 to form a back plate part 15 (but not limited to) on the back surface B of the organic light-emitting diode panel module 12 and attached to the back surface B of the organic light-emitting panel module 12, wherein the back surface B of the organic light-emitting panel module 12 is shown as Figure 3 corresponding to the surface of the organic light-emitting panel module 12 and the normal direction N in reverse direction, so as to save the installation space of the flexible circuit board 14 in the organic light-emitting diode display device 10 to achieve the display device thin and narrow frame effect. In addition, in the preferred embodiment, as shown by Figure 1 and Figure 2 It can be seen that the organic light-emitting diode display device 10 can also include a back plate 18 (but not limited to), the back plate 18 accommodates the organic light-emitting diode panel module 12, so as to integrate the appearance shell and support the internal components of the organic light-emitting diode display device 10.

[0047] As for the fixed design of the decorative plate structure 16, please refer to Figures 1 to 8 , Figure 4 , Figure 2 the frame 20 of Figure 5 is a perspective view of the first adhesive tape 22 adhered to Figure 4 the frame 20 of Figure 6 is a perspective view of the support plate 26 adhered to Figure 5 the first adhesive tape 22 of Figure 7 is a perspective view of the second adhesive tape 28 adhered to Figure 6 the support plate 26 of Figure 8 is a partial cross-sectional view of the organic light-emitting diode display device 10 along the cross-sectional line A-A of Figure 1 is a partial cross-sectional view of the organic light-emitting diode display device 10 along the cross-sectional line A-A of Figures 1 to 8As shown, the decorative panel structure 16 includes a frame 20, a first adhesive tape 22, and a decorative panel member 24. The frame 20 is positioned at a location corresponding to the bottom edge E of the back panel 18 (e.g., it can be positioned at a location corresponding to the bottom edge E of the back panel 18) and avoids the folded portion 15 of the flexible circuit board 14 to form a recess 21, such that the flexible circuit board 14 is accommodated in the recess 21, and the frame 20 and the flexible circuit board 14 do not overlap each other in the normal direction N of the organic light-emitting diode panel module 12 (e.g., ...). Figure 4 As shown, this provides a layout space inside the organic light-emitting diode display device 10 that avoids the flexible circuit board 14 and is available for tape application.

[0048] Through the aforementioned frame clearance design, the first adhesive tape 22 can be designed to overlap with the shape of the frame 20, so as to be adhered to the frame 20 without being adhered to the flexible circuit board 14 (e.g., Figure 5 As shown), the decorative panel component 24 can be attached to the first adhesive tape 22 to cover the bottom edge E and the flexible circuit board 14, thereby preventing the user from seeing the internal components of the organic light-emitting diode display device 10 during use, thus improving the overall aesthetics and user experience of the organic light-emitting diode display device 10. More specifically, in this embodiment, the decorative panel component 24 may include a support plate 26, a second adhesive tape 28, and a decorative panel 30. The support plate 26 can be attached to the first adhesive tape 22 to cover the flexible circuit board 14 (e.g., as shown). Figure 6 As shown), the second adhesive tape 28 is attached to the support plate 26 (as shown). Figure 7 As shown), and the decorative panel 30 is attached to the second adhesive tape 28 (as shown). Figure 8 As shown), the support plate 26 can provide full-area support to the trim panel 30 to solve the problem of insufficient structural support strength of the trim panel 30 at the location where it covers the flexible circuit board 14, thereby improving the overall structural strength of the trim panel component 24.

[0049] It should be noted that in practical applications, by Figure 5 It is understood that the first adhesive tape 22 can preferably extend to the area E at the bottom edge of the board where the flexible circuit board 14 is not provided to form a reinforcing adhesive area 23. Thus, the first adhesive tape 22 and the reinforcing adhesive area 23 can together at least partially surround the flexible circuit board 14 for subsequent attachment of the support plate 26. The extension range of the reinforcing adhesive area 23 is within... Figure 5The reinforcing glue area 23 can continue to extend inwardly in a second direction D2 opposite to the first direction D1 to overlap with a portion of the front panel glass G of the organic light emitting diode panel module 12 adjacent to the bottom edge E, so that the reinforcing glue area 23 and the first adhesive tape 22 can completely or partially surround the flexible circuit board 14, thereby further improving the glue fixing strength of the trim plate structure 16. In addition, the above-mentioned extension design can also be applied to the second adhesive tape 28, so that the second adhesive tape 28 can preferably extend inwardly from the bottom edge E to the second direction D2 to overlap with the front panel glass G of the organic light emitting diode panel module 12 (as shown in Figure 7 When the trim plate 30 is attached to the second adhesive tape 28, it can partially cover the front panel glass G, thereby further improving the covering and decoration effect of the trim plate member 24.

[0050] It is worth mentioning that the above-mentioned support plate and the second adhesive tape are optional elements, thereby simplifying the trim plate structure design of the present application. For example, in another embodiment in which the support plate 26 and the second adhesive tape 28 are omitted, the trim plate 30 can be directly attached to the first adhesive tape 22 as shown in Figure 5 Figure 5 to cover the bottom edge E of the organic light emitting diode panel module 12 and the flexible circuit board 14. The related description of other designs (such as the reinforcing glue area design and the front panel glass covering design) for this embodiment can be referred to the above-mentioned embodiments by analogy, and will not be described here.

[0051] In summary, compared with the glue dispensing fixing design of the prior art in which the front trim plate is attached to the flexible circuit board by dispensing glue, the present application adopts the frame dispensing design in which the frame formed with the accommodation notch is arranged at the position of the panel bottom edge to provide the glue dispensing space avoiding the flexible circuit board, thereby achieving the fixing effect that the trim plate member is fixed by glue surface dispensing only to the frame but not to the flexible circuit board. In this way, the present application can effectively solve the problems of the glue dispensing design of the prior art, i.e. the glue cannot be evenly distributed on the front trim plate and overflow glue is generated, and the flexible circuit board is damaged when the front trim plate is removed for maintenance. Therefore, the present application greatly improves the trim plate connection strength and disassembly convenience of the organic light emitting diode display device, and reduces the trim plate disassembly and maintenance cost of the organic light emitting diode display device.

[0052] The present application has been described by the above-mentioned embodiments, however, the above-mentioned embodiments are only examples for implementing the present application. It must be pointed out that the disclosed embodiments do not limit the scope of the present application. On the contrary, modifications and improvements made without departing from the spirit and scope of the present application are also within the scope of the patent protection of the present application.
