Abstract: Display driving device and method are provided. The display driving device includes a timing controller configured to compare previous pixel data and current pixel data in units of a line, add or subtract n-bit weight data to or from the current pixel data based on the compared result, and generate the added or subtracted current pixel data as overdriving pixel data, and a channel driver configured to transmit a gray scale voltage corresponding to the overdriving pixel data to a display panel, during an overdriving operation.

Abstract translation: 提供显示驱动装置和方法。 显示驱动装置包括：时序控制器，其被配置为基于比较结果将行的单位中的先前像素数据和当前像素数据进行比较，并根据比较结果对当前像素数据添加或减去n比特加权数据，并生成添加的或 减去当前的像素数据作为过驱动像素数据，以及通道驱动器，被配置为在过驱动操作期间将对应于过驱动像素数据的灰度级电压发送到显示面板。

Abstract: A semiconductor device is disclosed. The semiconductor device includes a transceiver including an amplifier region configured to output a data signal to a source line connected to a pixel during a first period and receive a detection signal from a touch electrode during a second period different from the first period, and configured to generate the data signal based on input data; and a driving controller configured to generate the data based on input image data, outputting the data to the transceiver, and generate a touch signal based on the detection signal.
