Display device

The present invention relates to a display device, and more particularly to a display device having a control module and a control button assembly disposed on the display body.

The control methods of the existing display devices generally adopt two types of wireless control and wired control. Wireless control usually uses wireless, Bluetooth, or wireless radio technology to transmit control signals wirelessly. This type of control requires an external remote control. The wired control usually sets a control button on the display body, which is directly connected to the internal processor of the display body, and can directly control the display body by operating the above control button, and the cable is abnormal when the remote control is abnormal, damaged or lost. Control can ensure the control work of the display body, which is of great significance.

At present, the control buttons provided on the display device have a single function, and can only realize a single switch on/off state, and can only implement a single function. If multiple control commands are to be designed to realize various functions, multiple buttons need to be set, so that It requires a large space for board use, which is contrary to the current trend of thinning and lightweight design, and the layout violates the user's intuitive usage habits, no function guiding interface, poor hand feeling, poor user experience, and specific browsing in the Internet. In the use environment, multiple repetitive operations are required, the operation procedure is increased, the user operation time is wasted, and the user is inconvenient in use.

The user presses the push handle 05 to press the push handle 05 to force When the reed 03 is bent down to connect the base 04, the line can be electrically connected, and if the line is disconnected. 2 is a cross-sectional view showing another conventional control button, which includes a terminal 51, a body 52, a spring 53, a base 54, a push handle 55 and a waterproof film 56. The basic principle is the same as that before FIG. The user presses the push handle 55 to bend the reed 53 downward and connect it to the base 54 to effect the opening and closing of the line. The difference is that the waterproof membrane 56 prevents liquid from penetrating and avoids short circuit. The existing control button can only achieve a single switch on/off state, and it is difficult to correspond to a more complicated and diverse operating environment.

In view of this, the purpose of the present invention is to propose a display device, which is expected to be more suitable for a complex and diverse operating environment, and to improve the convenience of use, while saving space.
