Embodiment Construction

[0041] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this description will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

[0042] It will be understood that when an element or layer is referred to as being "connected to," "connected to" or "coupled to" another element or layer, it may be directly connected to, connected to, coupled to the other element or layer, or intervening. Elements or layers may appear. In contrast, when an element is referred to as being "directly connected to," "direct...

Abstract

The invention provides a touch control system which includes a touch panel, a touch control pen and a touch sensing controller. The touch panel includes a plurality of driving electrodes and a plurality of sensing electrodes. The touch control pen provides a pen frequency signal for detecting a touch control pen position and a touch control pen pressure to the touch panel. The touch sensing controller outputs a plurality of driving signals with different frequency components to the touch panel and determines at least one of touch coordinates of a finger and touch coordinates of the touch control pen based on a plurality of sensing signals received from the touch panel.

Description

technical field [0001] Exemplary embodiments of the present invention relate to a touch system and a touch sensing controller and a stylus applied to the touch system. More specifically, the present invention relates to a touch system capable of simultaneously realizing finger touch recognition and pen touch recognition and realizing multi-point recognition of a stylus, as well as a touch sensing controller and a stylus applied to the touch system . Background technique [0002] Touch screen interfaces and stylus are widely used. Touch screen designs have incorporated many different technologies including resistive, capacitive, inductive and radio frequency sensing arrays. For example, a resistive touch screen is an excellent passive device for use with a passive stylus. [0003] While resistive touchscreens can sense input from almost any object, multi-touch is generally not supported. An example of a multi-touch application can bring two or more fingers into contact wi...
