A QWERTY keyboard and a Cheonjiin keyboard which are representative of a conventional input system of a touch display have a problem that a size of each key is small or the number of touching increases when completing a corresponding letter, and have a screen covering phenomenon on the display due to screen occupation of the keyboards. The present invention is to solve the problems by using a method for closely arranging letters on two vertical end sides and functions on a horizontal bottom side of the screen in order to expand the size of the letters and the functions of a touch display and minimize the number of touches on the touch display. In other words, the present invention is to closely arrange the letters in a row on each of the two vertical end sides and one horizontal bottom side, in using an input system of the touch display. Thus, the present invention is to solve problems such as an increase in the number of touches, and the narrowness of the input system of the touch display by closely arranging the letters on the two vertical sides and the one horizontal bottom side. |
