Abstract

The present disclosure is related to a touch sensing system (100) and a display apparatus decreasing a sensing time and enabling an effective touch sensing, although a number of sensing electrodes (Rx1 to RxM) increases according to an increase of an area of a touch panel (110).

Description

[0001] Pursuant to 35 U.S.C. §119(a), this application claims priority to Korean Patent Application No. 10-2013-0133404, filed November 5, 2013, which is hereby incorporated by reference for all purposes as if fully set forth herein Explain the same. technical field [0002] The invention relates to a touch sensing system and a display device. Background technique [0003] With the development of the information society, various demands for display devices that display images are increasing, and various display devices such as liquid crystal display (LCD) devices, plasma display panels (PDP) and organic light emitting diode (OLED) displays are being used recently device. [0004] Breaking through common input methods such as pressing keys, keyboards, mice, etc., display devices provide touch-based input methods that enable users to easily, directly, and conveniently input information or instructions. For a touch-based input method, a touch panel should be included in the d...
