[0184] (1) Measurement of unit resistance and transmittance corresponding to Y value

[0185] Figure 12 and Figure 13 A graph obtained by calculating the Y value of the prepared group by substituting the P1, P2, P3, and A values ​​into Mathematical Formula 1 and measuring the cell resistance and transmittance corresponding to the Y value is shown.

[0186] 1) Measurement of unit resistance

[0187] The linear resistance between one end and the other end of the sensing electrode located in the unit pixel of the prepared group was calculated using an electrical simulator (Q3D, Ansys Corporation).

[0188] The cell resistance corresponding to the Y value is shown in the Figure 12 and Figure 13 middle.

[0189] 2) Measurement of transmittance

[0190] A haze meter (HM-150, Murakami Company) was used to measure the total light transmittance of the touch sensing electrodes of the prepared group, and the transmittance was calculated relative to the glass substrate.

Abstract

The present invention relates to a touch screen panel and, more specifically, to a touch screen panel which meets mathematical equation 1, thereby having remarkably low sensing electrode resistance and thus having excellent touch sensibility, the touch screen panel comprising: a touch sensing electrode; and a pixel part arranged on the lower section of the touch sensing electrode, wherein the touch sensing electrode comprises: a sensing pattern provided with a first pattern formed in a first direction and a second pattern formed in a second direction; a bridge electrode for electrically connecting spaced unit patterns of the second pattern; and an auxiliary pattern provided to the upper section or the lower section of at least one of the first pattern and the second pattern, and the pixel part comprises a plurality of unit pixels.

Description

technical field [0001] The invention relates to a touch screen panel. Background technique [0002] Generally, a touch screen panel is a screen panel equipped with a special input device to receive a position input generated by a user's finger touching the screen. This type of touch screen panel has a multi-layered structure configured to receive input data directly from the screen so that the user's finger or object touches characters or specific characters displayed on the screen without using a keyboard. When the touch screen is in a certain position, the touch screen can recognize the position and perform specific processing through the software stored in it. [0003] In order to recognize the touch position without reducing the visibility of the image displayed on the screen, it is necessary to use a transparent touch sensing electrode, and generally a sensing pattern with a predetermined pattern is used. [0004] Such sensing electrodes are usually formed by a first ...
