Description
The present invention relates to a mobile terminal having a blind layer so that the dome switch is not visible between the side key of the side and the case.
The terminal can move And can be divided into a mobile / portable terminal and a stationary terminal depending on whether the mobile terminal is a mobile terminal or a mobile terminal. The mobile terminal can be divided into a handheld terminal and a vehicle mount terminal according to whether the user can directly carry the mobile terminal.
Such a terminal has various functions, for example, in the form of a multimedia device having multiple functions such as photographing and photographing of a moving picture, reproduction of a music or video file, reception of a game and broadcasting, etc. .
In order to support and enhance the functionality of such terminals, it may be considered to improve the structural and / or software parts of the terminal.
Recently, as the size of the front display unit increases, there is a tendency to minimize a key for inputting a user command on the front side. Therefore, the weight of the side keys is increasing. In addition, as the slimming of the mobile terminal proceeds, the size of the side keys is also becoming thinner.
The present invention has been proposed to meet the above-described needs, and an object thereof is to provide a mobile terminal having a blind layer and a control method thereof so that the dome switch is not visible between the side key of the side and the case.

It will be possible.
In order to achieve the above object, the present invention includes a case having a printed circuit board mounted with a plurality of chipsets therein and an opening formed on a surface thereof, and including a button unit for inputting a predetermined command by a user by pressing the case. The side key is inserted into the opening of the side, one side is located on the rear of the side key and the other side is electrically connected to the printed circuit board, and includes an auxiliary substrate for transmitting an electrical signal to the printed circuit board when the button portion is pressed Provide a mobile terminal.
In this case, the auxiliary substrate is disposed on the rear side of the side key, the rigid substrate having a signal terminal at a position corresponding to the button portion on the rigid substrate, when the button portion is pressed by the user is pressed together to connect the signal terminal A metallic dome switch protruding in a shape, a flexible substrate having a circuit pattern electrically connecting the signal terminal of the rigid board and the printed circuit board, and a blind layer formed in a dark color on an upper surface of the dome switch. do.
The effect of the mobile terminal according to the present invention will be described below.
According to at least one of the embodiments of the present invention, even if the length of the short side of the side key is smaller than the diameter of the dome switch, the metallic silver color of the dome switch is not visible through the gap between the side key and the case of the side surface of the mobile terminal. There is an advantage that the thickness of the mobile terminal can be made thin without inhibiting it.
The effects obtained by the present invention are not limited to the above-mentioned effects, and other effects not mentioned can be clearly understood by those skilled in the art from the following description will be.
