Abstract
A case in which an electronic component is mounted therein and a through-window is formed on a front surface thereof; A display unit disposed inside the case toward the through window; A window glass that covers the through-window and is coupled to the case and includes a bezel formed of an opaque material around the light-transmitting portion except for the light-transmitting portion corresponding to the display portion; A user input unit including a key pattern groove formed by etching a portion of the bezel and a touch sensor formed on a rear surface of the key pattern groove; A light emitting unit including a light guide layer positioned behind the user input unit and a light source positioned at a side of the light guide layer; And a light diffusion preventing unit positioned between the light emitting unit and the window glass to prevent light diffusion, thereby eliminating light bleeding through the key pattern groove of the user input unit, thereby clearly displaying the key pattern shape. The mobile terminal can be provided with a clean appearance.
Description
The present invention relates to a mobile terminal having a neat appearance by preventing the bleeding of light emitted from the front user input unit.
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 the mobile terminal, the keypad and various buttons are omitted while the touch screen is being applied. The user input unit using the touch method forms a key pattern groove in the bezel and includes a lamp to emit light through the groove to display the position of the user input unit.
An object of the present invention is to provide a mobile terminal further comprising a light diffusion preventing unit that can prevent the light bleeding emitted through the touch type user input unit disposed on the front of the mobile terminal.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention, unless further departing from the spirit and scope of the invention as defined by the appended claims. It will be possible.
In order to achieve the above object, the present invention, the electronic component is mounted therein, a case formed with a through window on the front; A display unit disposed inside the case toward the through window; A window glass that covers the through-window and is coupled to the case and includes a bezel formed of an opaque material around the light-transmitting portion except for the light-transmitting portion corresponding to the display portion; A user input unit including a key pattern groove formed by etching a portion of the bezel and a touch sensor formed on a rear surface of the key pattern groove; A light emitting unit including a light guide layer positioned behind the user input unit and a light source positioned at a side of the light guide layer; And a light diffusion preventing unit positioned between the light emitting unit and the window glass to prevent light diffusion.
The light diffusion preventing unit may use a convex lens formed between the rear surface of the key pattern groove and the touch sensor. The convex lens may be formed by applying an SVR (Super View Resin) to a convex shape on a rear surface of the key pattern groove.
The light diffusion preventing unit may use a tapered portion or a step portion formed between the back surface of the key pattern groove and the light guide layer.
According to at least one embodiment of the present invention, the light pattern emitted through the key pattern groove of the user input unit can be eliminated so that the shape of the key pattern can be clearly seen to provide a mobile terminal having a clean appearance.
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.
