Abstract
(EN) A touch display unit (1) and an electronic device (100). The touch display unit (1) comprises a touch display panel (10) and a driving circuit (20). The touch display panel (10) comprises a plurality of common electrodes (101) arranged in a two-dimensional array. The driving circuit (20) is used for providing a same first common voltage to the plurality of common electrodes (101) for executing image displaying and further driving the common electrodes (101) to execute self-capacitance touch sensing. The first common voltage is a signal modulated by using a modulation signal. The driving circuit (20) comprises a modulation end and a modulation circuit (21). The modulation circuit (21) is used for generating the modulation signal. When the modulation circuit (21) outputs the modulation signal to the modulation end, the driving circuit (20) drives the touch display panel (10) to execute image display refreshing and the self-capacitance touch sensing simultaneously. All signals on the touch display panel (10) are signals synchronously modulated by using the modulation signal. The electronic device (100) comprises the touch display unit (1).
(FR) L'invention concerne une unité (1) d'affichage tactile et un dispositif électronique (100). L'unité (1) d'affichage tactile comporte un panneau (10) d'affichage tactile et un circuit (20) d'attaque. Le panneau (10) d'affichage tactile comporte une pluralité d'électrodes communes (101) disposées en un réseau bidimensionnel. Le circuit (20) d'attaque est utilisé pour fournir une même première tension commune à la pluralité d'électrodes communes (101) pour exécuter un affichage d'image et attaquer en outre les électrodes communes (101) pour exécuter une détection tactile à capacité propre. La première tension commune est un signal modulé en utilisant un signal de modulation. Le circuit (20) d'attaque comporte une extrémité de modulation et un circuit (21) de modulation. Le circuit (21) de modulation est utilisé pour générer le signal de modulation. Lorsque le circuit (21) de modulation délivre le signal de modulation à l'extrémité de modulation, le circuit (20) d'attaque amène le panneau (10) d'affichage tactile à exécuter simultanément le rafraîchissement d'affichage d'image et la détection tactile à capacité propre. Tous les signaux sur le panneau (10) d'affichage tactile sont des signaux modulés de façon synchrone en utilisant le signal de modulation. Le dispositif électronique (100) comporte l'unité (1) d'affichage tactile.
(ZH) 一种触摸显示装置(1)和电子设备(100)。触摸显示装置(1)包括触摸显示面板(10)和驱动电路(20)。触摸显示面板(10)包括多个公共电极(101),呈二维阵列排布。所述驱动电路(20)用于提供相同的第一公共电压给所述多个公共电极(101)执行图像显示的同时,进一步驱动公共电极(101)执行自电容触摸感测,其中,所述第一公共电压为经一调制信号调制后的信号。所述驱动电路(20)包括调制端和调制电路(21)。所述调制电路(21)用于产生所述调制信号。当所述调制电路(21)输出所述调制信号给所述调制端时,所述驱动电路(20)驱动所述触摸显示面板(10)同时执行图像显示刷新与自电容触摸感测,其中,所述触摸显示面板(10)上的信号均为经所述调制信号同步调制后的信号。所述电子设备(100)包括所述触摸显示装置(1)。
