Abstract
A mobile terminal and an operating method of the mobile terminal are provided. The mobile terminal includes a transparent conductive layer configured to have a plurality of cells whose charge quantity varies in response to a touch signal, the cells being electrically isolated from one another; a plurality of pressure sensors configured to be laid over the transparent conductive layer, the pressure sensors calculating a pressure level of the touch signal and identifying a point of detection of the calculated pressure level; and a controller configured to determine whether there are two or more cells in the transparent conductive layer where a charge quantity variation is detected, wherein, if there are two or more cells in the transparent conductive layer where a charge quantity variation is detected, the controller identifies the positions of the corresponding cells and performs operations corresponding to the identified cell positions. Therefore, it is possible to effectively detect even a multi-touch input using the pressure sensors.
