    • An active matrix display device having touch input functionality is provided. The device comprises a plurality of pixels arranged in a row and column array, each pixel comprising a pixel electrode (11) to which data voltages can be supplied by an associated data conductor (12) via a respective thin film transistor (13) having a drain terminal connected to the pixel electrode. The pixels each further comprise a body (30;70;80) which electrically connects the associated pixel electrode to another electrode (51;14) in response to touch-input to the pixel, the connection being detectable via the associated data conductor. The circuitry used to address the display can also be used to detect any touch-input to the display, including pressure-sensitive and optical touch-input. This advantageously eliminates the requirement for extra conductors to perform the touch-input detection.
    • 提供具有触摸输入功能的有源矩阵显示装置。 该器件包括排列成行和列阵列的多个像素,每个像素包括像素电极(11),数据电压可由相关联的数据导体(12)通过相应的薄膜晶体管(13)提供给数据电压, 漏极端子连接到像素电极。 每个像素还包括主体(30; 70; 80),其响应于对像素的触摸输入将相关联的像素电极电连接到另一电极(51; 14),该连接可通过相关联的数据导体检测。 用于寻址显示器的电路也可用于检测显示器的任何触摸输入,包括压敏和光学触摸输入。 这有利地消除了对额外导体执行触摸输入检测的要求。
