Abstract

This invention reveals a kind of input equipment and the method for a touch-controlled keyboard writing input plate. It is mainly applied for handheld electronic equipment. It comprises a function key, a writing-input plate, a thin-film, and a backlight unit. The function key switches the functions between the hand-pressing operation and the pen-writing operation. The writing-input plate is an interface utilized for detecting input statuses. The thin-film surface printed with numeral key input patterns is attached to the surface of the writing-input plate. The backlight unit under the writing-input plate is triggered and ignited by the sensor that output touch-controlled signals. Therefore, it increases the convenience of the operation for a user. Moreover, the input method utilizes a driving circuit to detect the hand-pressing input status or the pen-writing input status from the writing-input plate, it detects the position of the touched point on the writing-input plate. An identifying function transmits the data into the inner core of a mobile phone, the inner core process in the mobile phone completes the identifying function, it inputs symbols and characters. This invention possesses the optimum design of a keyboard, it accelerates the input speed of symbols and characters. Especially, it facilitates the user who is not familiar with phonic spelling. It decreases the difficulty of the spatial allocation in a mobile phone. Eventually, it accords with the market requirement of light, thin, and small for a mobile phone.
