Description

Display device

The invention relates to a protection technology, especially a display device.

The design of today's display devices is developing towards a trend of high resolution. In the pursuit of high resolution, the driver chips or other electronic components required are more and more and the layout of the driver circuit is more and more complicated. Therefore, the display device also requires protection of the driver chips or other electronic components. Increasingly harsh.

Generally speaking, the current commonly used protection technology is to use a fastener (such as a screw) to lock the protective casing to the side wall of the front frame or the plastic frame, and the fastener to the driver chip or other electronic components The gap between them, so that the protective casing is located outside the driving chip or other electronic components.

However, since the current protection technologies all require the use of locking hardware to couple the protective casing to the side wall of the front frame or the plastic frame, the layout of the driving circuit needs to reserve space for the locking hardware to attach. As a result, it is more difficult to install the protective casing, and the locking member not only takes up a lot of space in the layout of the driving circuit, but also increases the overall thickness of the display device.

An embodiment of the present invention provides a display device including a first frame body, a second frame body, a display panel, a backlight module, a circuit element, and at least one protection element. The first frame has a support portion and a first side wall connected to the support portion. The second frame body has a cover portion and a second side wall connected to the cover portion. The second side wall is located outside the first side wall and the second side wall has at least one slot. The display panel is located between the cover portion and the support portion. The backlight module is located below the support portion and inside the first side wall. The circuit element includes a circuit carrier board and at least one driving chip. The driving chip is located on the circuit carrier board, and the circuit carrier board is located between the first side wall and the second side wall. The circuit board has a first edge and a second edge connected to the first edge. The first edge is connected to one side of the display panel. The protection member includes a protection side wall and at least one hook piece connected to the protection side wall. The protective side wall is located outside the second side wall. The hook piece extends toward the second side wall and hooks into the slot of the second side wall to be located at the second edge of the circuit board.

In summary, in the display device according to the embodiment of the present invention, the protection member is coupled to the outside of the second frame body by the hooking method and the cover is provided outside the corresponding driving chip, thereby providing the shielding and protection effects to the driving chip. Compared with the display device using the conventional protective casing, the embodiment of the present invention does not need to lock the additional locking member on the second side wall, therefore, the layout space occupied by the locking member is reduced, and the protection member is greatly reduced Difficulty in installation and significantly reduce the overall thickness.
