The first embodiment is as follows:
the utility model provides a display device.
In the embodiment of the present invention, please refer to fig. 1 and fig. 3 in combination, the display device includes a center frame 100 and a display panel 200, the center frame 100 includes a supporting platform 110 and a limiting wall 120 protruding from the supporting platform 110, the display panel 200 is lapped on the supporting platform 110 and contacts the supporting platform 110, a gap 102 is provided between a side wall of the display panel 200 and the limiting wall 120, and the gap 102 is filled with a bonding glue 800.
A display device, such as a computer, a television or a mobile phone, has a display panel 200 for a user to view pictures, and further includes a backlight module for providing light to the display panel 200, wherein the backlight module includes a middle frame 100, and the middle frame 100 is used to support the display panel 200. In the technical solution of the present invention, the middle frame 100 includes a supporting platform 110 and a protruding limiting wall 120 disposed on the supporting platform 110. The supporting platform 110 is used to support the display panel 200, wherein the supporting platform 110 may be a flat plate structure, or the supporting platform 110 may include supporting legs and a supporting flat plate connected to the supporting legs, and one side of the supporting flat plate departing from the supporting legs is used to support the display panel 200. The limiting wall 120 is used for shielding the side wall of the display panel 200 and has a better protection effect on the side wall of the display panel 200, so as to prevent the display panel 200 from sliding off from the side surface easily during the transportation process of the display device. By arranging the gap 102 between the side wall of the display panel 200 and the limiting wall 120 and filling the bonding glue 800 in the gap 102, the effect that the display panel 200 is fixedly connected to the middle frame 100 is achieved, and the display panel 200 is ensured to have a stable installation state.
