Abstract

Electrostatic capacitive touch screen panel. A touch-sensitive display includes a plurality of electrodes configured to detect touch input received at the touch-sensitive display device. A plurality of touch lines formed on the substrate are electrically connected to the electrodes and configured to detect a touch input received at the touch-sensitive display device. The plurality of first conductive patterns on the substrate are each connected to a touch line and extend from a corresponding touch line in a first direction. An insulating layer is disposed on the plurality of touch lines and the plurality of first conductive patterns, and a plurality of second conductive patterns is disposed on the insulating layer. Each second conductive pattern is in contact with a corresponding one of the touch lines via a contact hole in the insulating layer, and is at least partially connected to the corresponding one of the first conductive patterns while being separated by the insulating layer. The corresponding one of the first conductive patterns overlaps.

Description

technical field [0001] The present disclosure relates to a touch screen panel, and in particular, to an electrostatic capacitive touch screen panel that eliminates static electricity to improve the accuracy of touch perception. Background technique [0002] In recent years, display panels such as liquid crystal display panels, electroluminescent display panels, and plasma display panels, which have a fast response speed, low power consumption, and excellent color reproduction, have come into focus. These display devices have been used in various electronic products such as televisions, monitors of computers, laptop computers, tablet computers, mobile phones, industrial terminals, personal digital assistants, and automatic teller machines. Generally, these display devices interface with various input devices such as keyboards, mice, and digitizers. However, in order to use a separate input device such as a keyboard or mouse to perform tasks on a machine that includes a displ...
