Description

Technical Field

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

[0002] The market size of splicing panels has been growing year by year. LCD splicing panels occupy the mid-to-low-end market with their price advantage. In the high-end market, small-seam LED splicing panels are the mainstream products. The seam is the main bottleneck that restricts LCD splicing from entering the high-end products. The development of zero-seam LCD splicing products can enhance product competitiveness and seize the indoor high-end market of LED splicing panels, such as radio and television media, big data centers, etc.

[0003] During the research and practice of the prior art, the inventor of the present application found that the existing liquid crystal splicing panel is directly attached to the LED substrate at the seam, which is not conducive to the subsequent disassembly of the LED substrate.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the directional words such as "upper" and "lower" used generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0070] The embodiment of the present application provides a hybrid display device, which is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0071] It should be noted that the embodiments of the present application are described by taking the display device 100 as a liquid crystal display device as an example, but are not limited thereto. For example, in some embodiments of the present application, the panel may also be a light emitting diode panel, such as a micro light emitting diode panel, a sub-millimeter light emitting diode panel, an organic light emitting diode panel, or a quantum dot light emitting diode panel.

[0072] When the panel is a light emitting diode panel, the panel is placed in the receiving groove rn of the back plate 111. For the description of the back plate 111 and the connection structure between the back plate 111 and the middle frame, please refer to the following text, which will not be repeated here.

[0073] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides a hybrid display device 1000 , which includes at least two display devices 100 , a middle frame 200 and a light emitting diode substrate 300 .

[0074] Two adjacent display devices 100 are spliced ​​to form a gap fx. Each display device 100 includes a back plate 111 and a panel 12 disposed on the back plate 111 .

[0075] Combination Figure 3 The middle frame 200 includes a bearing portion 21 and a fixing portion 22 connected to the bearing portion 21. The bearing portion 21 is disposed on two adjacent panels 12 and blocks the gap fx. The fixing portion 22 is disposed in the gap fx and is detachably connected to the back panel 111.

[0076] The light emitting diode substrate 300 is disposed on the supporting portion 21 .

[0077] The display device 100 includes a backlight module 11 disposed on the light incident side of the panel 12 . The backlight module 11 includes a back plate 111 .

[0078] The hybrid display device 1000 of this embodiment not only uses the middle frame 200 to protect the panel 12, but also uses the middle frame 200 as a base to support the LED substrate 300. Since the middle frame 200 and the backlight module 11 of the display device 100 are detachably connected, and the LED substrate 300 is also disposed on the bearing portion 21 of the middle frame 200, the LED substrate 300 and the panel 12 can be separated at the same time as long as the middle frame 200 is disassembled, thereby reducing the difficulty of disassembling the LED substrate 300.

[0079] Optionally, the light-emitting diode substrate 300 can be an inorganic light-emitting diode substrate or an organic light-emitting diode (0LED) substrate, such as a micro light-emitting diode (Micro-LED) substrate, a sub-millimeter light-emitting diode (Mini-LED) substrate, or a quantum dot light-emitting diode (QLED) substrate.

[0080] Optionally, the hybrid display device 1000 further includes a flexible circuit board 400. The flexible circuit board 400 is connected to the side of the LED substrate 300 facing the gap fx. An opening 21a is provided on the carrier 21. The flexible circuit board 400 penetrates the opening 21a and is disposed in the gap fx.

[0081] Among them, an opening fx is set on the bearing portion 21 to facilitate the flexible circuit board 400 to pass through the bearing portion 21 and enter the gap fx, thereby avoiding the flexible circuit board 400 from entering the gap fx around the outer surface of the bearing portion 21, reducing the setting height of the light-emitting diode substrate 300, saving layout space and shortening the length of the flexible circuit board 400.

[0082] In some embodiments, the carrier portion 21 may not have an opening. In this case, the flexible circuit board 400 is bound to the side or front of the LED substrate 300 , and the flexible circuit board 400 extends around the outer surface of the carrier portion 21 into the gap fx.

[0083] Optionally, the thickness d1 of the bearing portion 21 is smaller than the thickness d2 of the fixing portion 22 .

[0084] The relatively small thickness of the bearing portion 21 can reduce the abruptness of the LED substrate 300 being disposed on the panel 12 ; the relatively thick thickness of the fixing portion 22 can improve the stability of the connection between the support frame 112 and the back plate 111 .

[0085] Optionally, the LED substrate 300 blocks the carrying portion 21 , and an edge portion of the LED substrate 300 protrudes from the carrying portion 21 .

[0086] The LED substrate 300 and the carrier 21 are both arranged in the non-display area NA, and the LED substrate 300 blocks and protrudes from the carrier 21, which reduces the risk of the user seeing the carrier 21 in a side view and improves the display effect.

[0087] Optionally, the panel 12 includes a display area AA and a non-display area NA disposed around the display area AA. The non-display area NA includes a non-binding area NA1 and a binding area NA2 for binding a circuit board.

[0088] Combination Figure 2 and Figure 3 The bearing portion 21 includes a first portion 211 and a second portion 212. The first portion 211 is disposed on the binding area NA2. The second portion 212 is disposed on the non-binding area NA1. The width of the first portion 211 is greater than that of the second portion 212.

[0089] Among them, since in the splicing of two display devices 100, one side of the gap fx is the binding area NA1 of the non-display area NA, and the other side of the gap fx is the non-binding area NA1, and the width of the binding area NA2 is greater than the width of the non-binding area NA1; therefore, the width of the first part 211 is designed to be greater than the width of the second part 212, and the supporting part 21 can better block the non-display area NA and better support the light-emitting diode substrate 300.

[0090] Optionally, the opening 21 a is disposed on the first portion 211 and corresponds to the gap fx. The flexible circuit board 400 is located on a side of the fixing portion 22 close to the binding area NA2.

[0091] Among them, since the binding area NA2 is used to bind the flip chip film or the non-flip chip circuit board, the flexible circuit board 400 is arranged on the side close to the binding area NA2, so that the flexible circuit board 400 and the circuit board bound to the binding area NA2 are connected to the driving board together, which simplifies the connection steps and saves installation space.

[0092] Optional, see Figure 4 and Figure 5 The backlight module 11 includes a back plate 111. The back plate 111 includes a base 11a and a first wall 11b connected to the periphery of the base 11a. The base 11a and the first wall 11b define a receiving groove rn. The first wall 11b is provided with a limiting groove Xw and a first opening k1. The first opening k1 is provided at the bottom of the limiting groove Xw.

[0093] Combination Figure 2 and Figure 3The fixing part 22 includes a plate body 221 and a slot body 222 protruding from the plate body 221. The slot body 222 is provided with a second opening k2. The slot body 222 is arranged in the limiting slot Xw. The slot body 222 and the back plate 111 are detachably connected by a connecting member Lj. The connecting member Lj passes through the first opening k1 and the second opening k2.

[0094] Among them, the groove body 222 of the fixing part 22 cooperates with the limiting groove Xw of the back plate 111, which improves the accuracy and convenience of assembly; in addition, the connecting member Lj is used to realize the detachable connection between the middle frame 200 and the back plate 111.

[0095] Please refer to Figure 6 Optionally, the connecting member Lj includes a nut j1 and a stud j2 connected to the nut j1. The nut j1 is disposed in the avoidance groove br formed by the groove body 222. The stud j2 is threadedly connected to the first opening k1.

[0096] The nut j1 is arranged in the avoidance groove br formed by the groove body 222, which saves assembly space; and the stud j2 is screwed to the first opening k1, which avoids the use of a nut, reduces the difficulty of connection and saves materials.

[0097] In some embodiments, the connector Lj may be a plug connector, which is plug-fitted into the first opening k1.

[0098] Optional, please continue to refer to Figure 4 A plurality of bosses 11a1 are convexly provided on the base 11a. The bosses 11a1 are used to place the lamp board.

The snap-in block 11b2 is arranged in the snap-in groove 11b1, which saves space for arranging the snap-in block 11b2. The snap-in block 11b2 is used for snap-in connection with the snap-in lug 11g of the support frame 112. The snap-in lug 11g is arranged in the snap-in groove 11b1.

[0100] Optionally, the first enclosure 11b includes a side wall 11b3, and a plurality of side walls 11b3 are arranged one by one on a side edge of the base 11a. A gap jx and an expansion opening kc are arranged between two adjacent side walls 11b3. The gap jx and the expansion opening kc communicate with and separate the two adjacent side walls 11b3 to improve the adaptability of the first enclosure 11b and prevent the first enclosure 11b from being squeezed and damaged.

[0101] In addition, the expansion opening kc is located on the side of the gap jx close to the base 11a, and the expansion opening kc extends from the gap jx to the direction of the two adjacent side walls 11b3 to form an undercut space. When the two adjacent side walls 11b3 are squeezed outward, the expansion opening kc plays a buffering role, reducing the risk of the bottom of the side wall 11b3 being torn.

[0102] Optionally, the display device 100 includes a backlight module 11 disposed on the light incident side of the panel 12. The backlight module 11 includes a back plate 111 and a support frame 112. The support frame 112 is disposed in the receiving groove rn.
