Title
(EN) TOUCH AND DISPLAY CONTROL DEVICE WITH FAST TOUCH RESPONSIVENESS, DISPLAY DEVICE INCLUDING THE SAME, METHOD OF OPERATING THE SAME AND ELECTRONIC SYSTEM INCLUDING THE SAME
Abstract
(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.
