摘要

A liquid crystal display (LCD) protection film for a visually impaired person is disclosed. The LCD protection film according to the present invention is attached to the front side of a mobile terminal having a touch screen on the front side and comprises: first point factor units arranged at regular intervals in a protruding or recessed form along lengthwise edges on both sides of the touch screen; first line factor units formed longer than the first point factor units in a protruding or recessed form between the first point factor units along the direction of formation of the first point factor units; second point factor units arranged at regular intervals in a protruding or recessed form along widthwise edges on both sides of the touch screen; and second line factor units formed longer than the second point factor units in a protruding or recessed form between the second point factor units along the direction of formation of the second point factor units. By means of the present invention, the first point factor units, the first line factor units, the second point factor units, and the second point factor units which are formed along the edges of the touch screen are used as coordinates to minimize the portion of the screen inside the touch screen that is hidden, to prevent wrong inputs by a fixed sign, to enable any point formed inside the touch screen to be checked easily; and to enable not only a visually impaired person but also a person with low vision and any other person to use the LCD protection film.
