Problems solved by technology

[0013] In particular, when a partial short circuit occurs between the sensor pattern and the dummy pattern in the case where the dummy patterns are linked to each other compared to the case where the dummy patterns are not linked to each other, excessive capacitance changes due to the current flowing from the sensor pattern to all the dummy patterns. It hinders the recognition of the touch position, making it impossible to accurately determine the touch position

Abstract

A touch pad structure using a dummy pattern for a capacitance type touch screen by the present invention is disclosed. The touch pad structure using the dummy pattern for the capacitance type touch screen according to the present invention comprises: a firsts sensor unit in which first sensor patterns formed in the first direction and first dummy patterns formed between the first sensor patterns are aligned; and a second sensor unit which is overlapped with the first sensor unit, and in which second sensor patterns formed in the second direction crossing the first direction and second dummy patterns formed between the second sensor patterns are aligned. The first and second dummy patterns are formed of at least two sub dummy patterns each of which is physically separated.

Description

technical field [0001] The present invention relates to a touch panel structure for a capacitive touch screen, and more particularly relates to a touch panel structure for a capacitive touch screen using virtual patterns. Background technique [0002] Recently, various mobile terminals such as mobile phones, PDAs and MP3 players have gradually decreased in size in order to improve portability. In order to provide high-quality images through mobile terminals, the size of displays applied to mobile terminals increases. In order to meet the requirements of reducing the size of the mobile terminal and increasing the size of the display on the mobile terminal, a touch screen method is used to allow the user to perform input actions by himself. The touch screen method is applied to large TVs or displays such as Liquid Crystal Display (LCD), Plasma Display Panel (PDP), Organic Light Emitting Diode (OLED), and Active Matrix Organic Light Emitting Diode (AMOLED).
