    • In a display apparatus, one frame includes a first sub-frame in which a previous image is held and a second sub-frame in which a present image is displayed. A plurality of sensors recognizes an object disposed on a display panel and sequentially outputs sensing signals in response to scan signals. Sensing signals are divided into a first sensing signal read out during a first sub-frame and a second sensing signal read out during a second sub-frame, and a control circuit generates a noise free signal using the first and second sensing signals. Thus, a coordinate value indicating the position of the object may be generated based on the noise free signal, thereby preventing mis-operation or malfunction caused by the noise.
    • 在显示装置中,一帧包括保持先前图像的第一子帧和显示当前图像的第二子帧。 多个传感器识别设置在显示面板上的物体,并响应于扫描信号顺序地输出感测信号。 感测信号被分为在第一子帧期间读出的第一感测信号和在第二子帧期间读出的第二感测信号,并且控制电路使用第一和第二感测信号产生无噪声信号。 因此,可以基于无噪声信号产生指示对象的位置的坐标值,从而防止由噪声引起的错误操作或故障。

    • A display apparatus includes a display panel, a plurality of sensors, a read-out circuit, and a control circuit. The display panel includes a plurality of pixels receiving a data signal having a polarity reversed with respect to a common voltage to display an image. The sensors sense light to output sensing signals. The sensors may be integrated into the display panel. The read-out circuit is charged with the sensing signals generating charged signals in response to a sampling signal generated during a period in which the common voltage has a predetermined reference voltage level. The control circuit calculates a position on the display panel from the charged signals received signals from the read-out circuit.
    • 显示装置包括显示面板,多个传感器,读出电路和控制电路。 显示面板包括多个像素,其接收相对于公共电压具有极性反转的数据信号,以显示图像。 传感器感测光以输出感测信号。 传感器可以集成到显示面板中。 读出电路响应于在公共电压具有预定参考电压电平的时段期间产生的采样信号,产生感测信号,产生充电信号。 控制电路根据来自读出电路的充电信号接收信号来计算显示面板上的位置。
