    Abstract: A display device includes a data line, a pixel electrically connected to the data line, a data driver for outputting a data voltage, and a transmitter electrically connected between an output terminal of the data driver and the data line. The transmitter may transmit an instance of the data voltage to the data line in a first period. The transmitter may amplify a second instance of the data voltage to generate a reference voltage and then transmit the reference voltage to the data line in a second period different from the first period. The pixel includes a light emitting element for emitting light in response to the first instance of the data voltage. A voltage level of the reference voltage may be higher than a voltage level of the data voltage.

    Abstract: In an electronic device, touch coordinates, which are not pixel shift calibrated, are not transmitted from an application processor to a timing controller. Instead, pixel shift data are supplied to a touch position calculating unit disposed in a driving circuit or the application processor, and the touch position calculating unit generates pixel shift calibrated touch coordinates by reflecting the pixel shift data when calculating a touch position based on detection signals from a touch sensor. Accordingly, it is not necessary to transmit touch coordinates, which are not pixel shift calibrated, from the application processor to the timing controller, thereby decreasing a delay and power consumption due to frequency transception.

    Abstract translation: 在电子设备中,不进行像素移位校准的触摸坐标不会从应用处理器发送到定时控制器。 代替地,将像素移位数据提供给设置在驱动电路或应用处理器中的触摸位置计算单元,并且触摸位置计算单元通过基于检测信号计算触摸位置时反射像素移位数据来生成像素移位校准触摸坐标 从触摸传感器。 因此,不需要从应用处理器向定时控制器发送不进行像素移位校准的触摸坐标,从而减少由频率异常引起的延迟和功耗。
