Detailed ways

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

The present invention is described in detail in combination with schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional view showing the structure of the device will not be partially enlarged according to the general scale, and the schematic diagram is only an example, which should not limit the protection of the present invention. range.

As shown in conjunction with FIG. 1 and FIG. 2 , the display screen in this embodiment includes a display panel 1 and a housing 6 . Wherein, the display panel 1 includes a display area 11 and a fixed area 12, the display area 11 is used for displaying pictures, wherein the fixed area 12 is located at the corner area of the display panel 1, and the corner area of the display panel 1 is partially cut off, the display The screen also includes a fixing structure 3 through which the display panel 1 is fixed to the housing 6 , wherein the fixing structure 3 partly overlaps the fixing area 12 . The display panel 1 is only connected to the housing 6 through the fixing structure 3 in the fixed area 12 located in the corner area, so as to realize the fixing of the display panel 1. The part of the fixing structure 3 can fill the partially cut-off area of the display panel 1, effectively reducing the The frame width of the display screen is conducive to obtaining a large-size display screen through splicing. There is no overlapping area between the fixed area 12 and the display area 11, which will not affect the normal display of the display screen.

Preferably, the isosceles right-angled area of the corner area of the display panel 1 can be removed. As shown in FIG. The partially cut corner area, as shown in FIG. 1 and FIG. 3 , on the one hand, makes the connection firm; on the other hand, since the fixing structure 3 is only provided at the corner of the display panel 1 to fix the display panel 1, The bezel width of the display has been greatly reduced.

The fixing area 12 of the display panel 1 is engaged with the housing 6 through the fixing structure 3 . As shown in Figures 1 and 2, preferably, the fixing structure 3 is a triangle, and the overall outline of the fixing structure 3 after being clamped with the display panel 1 is consistent with the outline of the display panel 1 before being cut off, which can further reduce the size of the display panel. border width.

The fixing structure 3 has a card slot for clamping the display panel 1 and the housing 6, and the card slot is provided with a flange 31 on one side of the display panel, wherein the flange 31 extends toward the center of the display panel 1 and overlaps To the fixing area 12, a higher fixing strength can be provided, as shown in FIG. 2 .

Correspondingly, in order to achieve the purpose of fixing the display panel 1, the fixed structure 3 can be designed to be fixedly connected to the housing 6. Specifically, the bottom of the fixed structure 3 can be fixedly connected to the housing 6 through optical glue or double-sided tape, and the flange 31 is located on the display panel. The front side of the panel 1 overlaps the fastening area 12 .

It should be pointed out that, as shown in FIG. 3 , the display screen in the above-mentioned preferred embodiment of the present invention is also provided with a lead area 13 on the periphery of the display area 11, and the fixed area 12 falls into the corner area of the lead area, and the lead area The corner area of 13 is partially cut away. The lead wire area 13 is used to draw out the lead wires 14 such as gate lines, data lines, and common electrode lines of the display panel 1, so as to connect them with corresponding driving circuits, and provide the display panel with required gate line scanning signals, display grayscale signals, Common voltage signal, etc., to realize the driving display of the display screen.

Preferably, the lead area 13 is wired according to the edge shape of the lead area 13 to provide sufficient connection space for lead lines such as gate lines, data lines, and common electrode lines, and to avoid damage to the lead lines when cutting the lead area.

It can be seen from the above embodiments that the display screen provided by the present invention includes a display panel and a housing, wherein the display panel includes a display area and a fixed area, the fixed area is set at the periphery of the display area, and the display panel only passes through the fixed structure in the fixed area. The connection with the casing effectively reduces the frame width of the display screen, and even realizes a frameless display screen, which is beneficial to obtain a large-size display screen through splicing. Moreover, there is no overlapping area between the fixed area and the display area, which will not affect the normal display of the display screen.

As shown in Figure 2, preferably, the display screen of this embodiment is a liquid crystal display screen, which also includes a backlight module 2, the backlight module 2 is arranged between the display panel 1 and the housing 6, and the display panel 1 is in a fixed area 11 is connected with the backlight module 2 and the housing 6 through the fixing structure 3 .

It should be pointed out that the display panel 1 in the preferred embodiment of the present invention is only fixed in the fixed area of the corner area of the display panel 1, which greatly reduces the mechanical strength of the display panel. The side of group 2 away from the liquid crystal display is provided with a rib structure 4 for increasing the mechanical strength of the display. Since the display panel 1 is generally rectangular, the backlight module 2 matched with the display panel 1 is also roughly rectangular in structure, so the reinforcing rib structure 4 can be specifically designed to be distributed along the diagonal of the backlight module 2, as shown in FIG. 4 . Furthermore, it is also possible to design the rib structure 4 and the fixing structure 3 as an integral structure to further increase the mechanical strength of the display screen.

Preferably, the backlight module 2 includes a backlight that provides light for the display screen. As shown in FIG. 5 , a plurality of supporting structures 51 are also provided between the display panel 1 and the backlight module, for providing a certain light mixing distance for the backlight. And the two opposite surfaces of the support structure 51 are fixedly connected to the display panel 1 and the backlight module 2 respectively, specifically, the two opposite surfaces of the support structure 51 can be respectively connected to the display panel 1 and the backlight module by double-sided adhesive or optical glue. The module 2 is fixedly connected to further increase the fixing strength of the display panel 1 .

The present invention also provides a splicing screen, which includes a plurality of display screens 10 according to the above-mentioned technical solution. FIG. A through hole 511 is provided in the middle of the support structure 51 , as shown in FIG. 6 and FIG. 7 , so as to splice a plurality of display screens 10 to form a large-size display screen.

When splicing and making large-size display screens, the two ends of the buckle 7 can be stuck in the corresponding through holes 511 between adjacent display panels, as shown in Figure 9, to achieve fixed splicing without the need to make a separate fixing mechanism. The production process is reduced, and the production cost is reduced.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and replacements can also be made, these improvements and replacements It should also be regarded as the protection scope of the present invention.
