(EN) The present disclosure provides a touch and display control device with a touch screen controller and a display driver. The touch screen controller receives a touch sensing signal, generates touch raw data based on the touch sensing signal, and extracts touch information based on the touch raw data. The display driver receives an original image from a host processor, directly receives the touch information from the touch screen controller, generates touch trajectory information by accumulating the touch information, internally generates a touch image to be displayed with the original image based on the touch trajectory information, generates a composite image by synthesizing the original image and the touch image, and controls a display panel to display the composite image. The display driver includes a memory storing the touch trajectory information.
(ZH) 本公开提供了一种触摸和显示控制设备,具有触摸屏控制器和显示驱动器。触摸屏控制器接收触摸感测信号,基于触摸感测信号来生成触摸原始数据,并且基于触摸原始数据来提取触摸信息。显示驱动器从主机处理器接收初始图像,直接从触摸屏控制器接收触摸信息,通过累积触摸信息来生成触摸轨迹信息,基于触摸轨迹信息在内部生成要与初始图像一起显示的触摸图像,通过合成初始图像和触摸图像来生成复合图像,并控制显示面板显示复合图像。显示驱动器包括存储触摸轨迹信息的存储器。
