[0014] Furthermore, the display device also includes a second flexible circuit board, one end of which is connected to the short side of the direct display panel, and the other end of which is connected to the short side of the first printed circuit board.

[0015] Furthermore, the device portion of the first printed circuit board is located on a surface of the first printed circuit board that is away from the direct display panel.

[0016] Furthermore, the display device also includes a second printed circuit board and a third flexible circuit board. The second printed circuit board is disposed in the second accommodating space. The second printed circuit board is electrically connected to the direct display panel through the third flexible circuit board, and the second printed circuit board is electrically connected to the first printed circuit board.

[0022] The beneficial effects of this application are:

[0023] This application provides a display device comprising a liquid crystal display panel, a direct-view display panel, and a first printed circuit board. The liquid crystal display panel, a portion of the back cover, and the outer frame form a second accommodating space. The direct-view display panel is positioned to one side of the liquid crystal display panel, and the first printed circuit board is disposed within the second accommodating space. From a top-view perspective, a portion of the direct-view display panel overlaps with the first printed circuit board. Compared to conventional solutions, using a direct-view display panel instead of the front frame expands the display area of ​​the display device, thereby increasing its display size. Furthermore, since the first printed circuit board is disposed within the second accommodating space, from a top-view perspective, a portion of the direct-view display panel overlaps with the first printed circuit board. In other words, this technical solution places the first printed circuit board between the side wall of the liquid crystal display panel and the outer frame, rather than between the bottom wall of the liquid crystal display panel and the back cover, reducing the thickness of the display device and thus facilitating ultra-thin design.

[0037] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. The technical solutions described below are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.

[0038] Furthermore, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms "multiple" and similar words indicate two or more unless otherwise expressly specified.

[0039] The first embodiment of this application provides a display device, referencing... Figure 2 and Figure 3 The device includes an outer frame 100, a back cover 200, a liquid crystal display panel 300, a direct-view display panel 400, and a first printed circuit board 500. The back cover 200 is connected to the outer frame 100 and forms a first accommodating space Q1. The liquid crystal display panel 300 is disposed in the first accommodating space Q1, and the liquid crystal display panel 300, a part of the back cover 200, and the outer frame 100 form a second accommodating space Q2. The direct-view display panel 400 is located on one side of the liquid crystal display panel 300. The first printed circuit board 500 is disposed in the second accommodating space Q2. From a top-view perspective, a part of the direct-view display panel 400 overlaps with the first printed circuit board 500.

[0040] refer to Figure 1A conventional liquid crystal display device includes a liquid crystal display panel 101, a front frame 102, an outer frame 103, and a rear cover. The outer frame 103 and the rear cover are connected to form an accommodating space. The liquid crystal display panel 101 is disposed within the accommodating space. The front frame 102 is located on one side of the liquid crystal display panel 101 and is situated between the liquid crystal display panel 101 and the outer frame 103. The outer frame 103 supports the front frame 102. Because the front frame 102 of the conventional liquid crystal display device occupies a large area, and the area of ​​the front frame 102 cannot perform display functions, the display area of ​​the liquid crystal display device is not high. Therefore, the technical solution of this application sets the display device to include a liquid crystal display panel 300, a direct-view display panel 400, and a first printed circuit board 500. The liquid crystal display panel 300, a portion of the back cover 200, and the outer frame 100 form a second accommodating space Q2. The direct-view display panel 400 is located on one side of the liquid crystal display panel 300, and the first printed circuit board 500 is disposed within the second accommodating space Q2. From a top-down view of the display device, a portion of the direct-view display panel 400 overlaps with the first printed circuit board 500. Compared to conventional solutions, this solution uses a direct-view display panel 400. By replacing the front frame, the display area of ​​the display device can be expanded, thereby increasing the display area of ​​the display device; and since the first printed circuit board 500 is located in the second accommodating space Q2, from the perspective of looking down at the display device, a part of the direct display panel 400 overlaps with the first printed circuit board 500. That is, the display device of this technical solution places the first printed circuit board 500 between the side wall of the liquid crystal display panel 300 and the outer frame 100, rather than placing the first printed circuit board 500 between the bottom wall of the liquid crystal display panel 300 and the back cover 200, which can reduce the thickness of the display device, thereby facilitating the realization of ultra-thin display device thickness.

[0041] In this embodiment, the direct-view display panel 400 is a Micro LED display panel or a Mini LED display panel.

[0042] In this embodiment, reference Figure 3 The liquid crystal display panel 300 includes a backlight module 330, an array substrate 340, and an opposing substrate 350. The backlight module 330 is disposed in a first accommodating space Q1, the array substrate 340 is disposed on one side of the backlight module 330, and the opposing substrate 350 is disposed on the side of the array substrate 340 away from the backlight module 330.

[0043] In this embodiment, the first printed circuit board 500 is located between the backlight module and the outer frame 100.

[0044] In this embodiment, reference Figure 3The backlight module 330 also includes a back plate 331, a light guide plate 332, and a light strip 333. The back plate 331 has a third accommodating space Q3. The light guide plate 332 is disposed in the third accommodating space Q3. The light strip 333 is fixed to the side plate of the back plate 331, and the light-emitting surface of the light strip 333 faces the side wall of the light guide plate 332.

[0045] In this embodiment, a portion of the direct display panel 400 covers the light strip 333.

[0046] In this embodiment, one side of the direct display panel 400 is fixed to the liquid crystal display panel 300, and the other side of the direct display panel 400 is fixed to the outer frame 100.

[0047] In this embodiment, a support member (not shown in the figure) is also provided on the outer wall of the side plate of the back plate 331, wherein the first printed circuit board 500 is disposed on the support member.

[0048] In this embodiment, reference Figure 3 The liquid crystal display panel 300 includes a display portion 310 and a lower bezel portion 320. The lower bezel portion 320 is located on one side of the display portion 310. From a top-view perspective of the display device, a portion of the direct-view display panel 400 overlaps with at least a portion of the lower bezel portion 320, but the direct-view display panel 400 does not overlap with the display portion 310. By arranging the direct-view display panel 400 such that, from a top-view perspective of the display device, a portion of the direct-view display panel 400 overlaps with at least a portion of the lower bezel portion 320, but the direct-view display panel 400 does not overlap with the display portion 310, the direct-view display panel 400 only obscures the lower bezel portion 320 of the liquid crystal display panel 300, without obstructing the display portion 310 of the liquid crystal display panel 300. This avoids interference between the direct-view display panel 400 and the display of the liquid crystal display panel 300.

[0049] In this embodiment, reference Figure 3 , Figure 5The display device further includes a first flexible circuit board 600. One end of the first flexible circuit board 600 is connected to the liquid crystal display panel 300, and the other end of the first flexible circuit board 600 is connected to the long side of the first printed circuit board 500. A portion of the first flexible circuit board 600 is located between the first printed circuit board 500 and the direct display panel 400. By setting the other end of the first flexible circuit board 600 to be connected to the long side of the first printed circuit board 500, and a portion of the first flexible circuit board 600 to be located between the first printed circuit board 500 and the direct display panel 400, i.e., in this embodiment, the first printed circuit board 500 is folded to a side where a portion of the first flexible circuit board 600 is away from the direct display panel 400, the overlap area between the first printed circuit board 500 and the first flexible circuit board 600 in the direction from the sidewall of the liquid crystal display panel 300 to the outer frame 100 can be increased, thereby avoiding increasing the distance from the sidewall of the liquid crystal display panel 300 to the outer frame 100.

[0050] In this embodiment, reference Figure 3 The distance from the first flexible circuit board 600 to the outer frame 100 is less than the distance from the first printed circuit board 500 to the outer frame 100.

[0051] In this embodiment, the component portion of the first printed circuit board 500 is located on a surface of the first printed circuit board 500 that is away from the direct display panel 400. By positioning the component portion of the first printed circuit board 500 on a surface away from the direct display panel 400, it is possible to avoid the component portion of the first printed circuit board 500 being too close to the direct display panel 400, which could cause the electronic components in the component portion of the first printed circuit board 500 to collide with the direct display panel 400 and be damaged, thereby improving the stability of the display device.

[0052] In this embodiment, reference Figure 5 , Figure 6The display device further includes a second flexible circuit board 700, one end of which is connected to the short side of the direct-view display panel 400, and the other end of which is connected to the short side of the first printed circuit board 500. By including the second flexible circuit board 700, with one end connected to the short side of the direct-view display panel 400 and the other end connected to the short side of the first printed circuit board 500, the display device can be folded from the side to the side of the first flexible circuit board 600 away from the first printed circuit board 500, reducing the manufacturing difficulty. Furthermore, the liquid crystal display panel 300 and the direct-view display panel 400 can be controlled by the first printed circuit board 500, eliminating the need for an additional printed circuit board to control the direct-view display panel 400, thereby reducing the manufacturing cost of the display device.

[0053] When assembling the direct display panel 400 and the first printed circuit board 500, the first printed circuit board 500 is first folded over on the side facing the backlight module, so that the first printed circuit board 500 is located between the back cover 200 and the first flexible circuit board 600. Then, the direct display panel 400 is folded over from the short side of the first printed circuit board 500 to the side of the first printed circuit board 500 away from the back cover 200, so that a part of the first flexible circuit board 600 is located between the first printed circuit board 500 and the direct display panel 400, thereby realizing the assembly of the direct display panel 400 and the first printed circuit board 500.

[0054] In this embodiment, reference Figure 8 , Figure 9The display device further includes a second printed circuit board 800 and a third flexible circuit board 900. The second printed circuit board 800 is disposed in the second accommodating space Q2. The second printed circuit board 800 is electrically connected to the direct display panel 400 through the third flexible circuit board 900, and the second printed circuit board 800 is electrically connected to the first printed circuit board 500. The second printed circuit board 800 overlaps with a portion of the first printed circuit board 500 and a portion of the direct display panel 400. The display device further includes a second printed circuit board 800 and a third flexible circuit board 900. The second printed circuit board 800 is disposed within the second accommodating space Q2. The second printed circuit board 800 is electrically connected to the direct display panel 400 through the third flexible circuit board 900, and the second printed circuit board 800 is also electrically connected to the first printed circuit board 500. That is, the first printed circuit board 500 controls the liquid crystal display panel 300, and the second printed circuit board 800 controls the operation of the direct display panel 400. When the direct display panel 400 malfunctions, only the direct display panel 400 and the second printed circuit board 800 need to be disassembled and replaced separately, thereby reducing the maintenance cost of the display device.

[0055] In this embodiment, reference Figure 7 , Figure 8 The display device further includes a fourth flexible circuit board (not shown in the figure); wherein, the second printed circuit board 800 is located between the first flexible circuit board 600 and the direct-view display panel 400, the first printed circuit board 500 is provided with a first connector 510, and the second printed circuit board 800 is provided with a second connector 810, the second connector 810 being electrically connected to the first connector 510 through the fourth flexible circuit board. Since the second printed circuit board 800 is located between the first flexible circuit board 600 and the direct-view display panel 400, it is difficult for the second connector 810 to be directly connected to the first connector 510. Therefore, by including a fourth flexible circuit board in the display device, and the second connector 810 being electrically connected to the first connector 510 through the fourth flexible circuit board, it is beneficial to connect the second connector 810 to the first connector 510, thereby achieving the electrical connection between the liquid crystal display panel 300 and the direct-view display panel 400.

[0056] In this embodiment, reference Figure 7 , Figure 9The second printed circuit board 800 is located on the side of the first printed circuit board 500 away from the direct display panel 400. A first connector 510 is provided on the side of the first printed circuit board 500 closest to the second printed circuit board 800, and a second connector 810 is provided on the surface of the second printed circuit board 800 closest to the first printed circuit board 500. The second connector 810 is inserted into the first connector 510. By providing the first connector 510 on the side of the first printed circuit board 500 closest to the second printed circuit board 800, and the second connector 810 on the surface of the second printed circuit board 800 closest to the first printed circuit board 500, and the second connector 810 being inserted into the first connector 510, it is convenient to disassemble and install the second printed circuit board 800 and the first printed circuit board 500. It should be noted that in this embodiment, the length of the third flexible circuit board 900 has been increased, which facilitates the adjustment of the position of the second printed circuit board 800, so that the second printed circuit board 800 can be flipped to the side of the first printed circuit board 500 away from the direct display panel 400, so as to realize the insertion of the second connector 810 of the second printed circuit board 800 and the first connector 510 of the first printed circuit board 500.

[0057] In this embodiment, reference Figure 4 The display device further includes a touch sensor 1000, which is disposed on the side of the direct-view display panel 400 near the first printed circuit board 500 and electrically connected to the direct-view display panel 400. By including the touch sensor 1000 in the display device, and disposing it on the side of the direct-view display panel 400 near the first printed circuit board 500, and electrically connecting it to the direct-view display panel 400, the direct-view display panel 400 can be controlled by touch, thereby enhancing the interactive functionality of the display device.

[0058] In this embodiment, the touch sensor 1000 is a pressure-sensitive sensor.
