Summary:PROBLEM TO BE SOLVED: To provide a smart phone including a display module which can detect not only a position of touch on a touch screen but also magnitude of touch pressure.SOLUTION: A smart phone comprises: a cover layer; an LCD panel and a display module 200 disposed on a lower part of the cover layer, including a liquid crystal layer and a first glass layer and a second glass layer which sandwich the liquid crystal layer; pressure electrodes 450, 460 disposed on a lower part of the display module; and a noise shielding member disposed on a lower part of the pressure electrodes. At least a part of the touch sensor which senses touch by an electrostatic capacitance system is positioned between the first glass layer and second glass layer, and the touch sensor comprises plural drive electrodes and plural reception electrodes. A drive signal is applied to the touch sensor, a touch position is detected based on a sensing signal outputted from the touch sensor, and magnitude of touch pressure is detected based on a change amount of the electrostatic capacitance outputted from the pressure electrodes.SELECTED DRAWING: Figure 5 【課題】タッチスクリーン上のタッチの位置だけでなく、タッチ圧力の大きさを検出できるディスプレイモジュールを含むスマートフォンを提供する。【解決手段】スマートフォンは、カバー層と、その下部に位置し、液晶層及び液晶層を挟んで位置する第1ガラス層及び第2ガラス層を含むLCDパネル及びディスプレイモジュール200と、ディスプレイモジュールの下部に位置する圧力電極450、460と、圧力電極の下部に位置するノイズ遮蔽用部材と、を含む。静電容量方式でタッチを感知するタッチセンサの少なくとも一部が前記第1ガラス層と前記第2ガラス層との間に位置し、前記タッチセンサは、複数の駆動電極と複数の受信電極とを含み、前記タッチセンサに駆動信号が印加され、前記タッチセンサから出力される感知信号からタッチ位置を検出し、前記圧力電極から出力される静電容量の変化量に基づいてタッチ圧力の大きさを検出する。【選択図】図5
