Abstract

Disclosed are a touch display device, a touch system, a touch master, and a communication method and, more particularly, are a touch display device, a touch system, a touch master, and a communicationmethod which can provide a communication protocol and a communication interface based on a master-slave system in which a touch driving device operates as a touch slave and a touch controller operates as a touch master. Communication between the touch driving device and the touch controller can be accurately and rapidly performed and data transmission efficiency can increase.

Description

technical field [0001] The present invention relates to an apparatus and method for touch sensing. Background technique [0002] With the development of the information society, the demand for display devices for displaying images has been increasing in various forms, and in recent years, applications such as liquid crystal displays (LCDs), plasma display panels (PDPs), and organic light-emitting displays ( Various display devices such as OLED). [0003] Among these display devices, touch display devices may provide a touch-based input scheme that breaks general input schemes such as buttons, keyboards, or mice to allow users to easily, intuitively, and conveniently input information or instructions. [0004] In order to provide a touch-based input scheme of a touch display device, whether a user makes a touch should be detected and accurate touch coordinates (touch positions) should be detected. [0005] In order to correctly identify whether there is a touch or a touch p...
