TOUCH PANEL OF 5-WIRED ELECTRODE ANALOGUE RESISTOR FILM METHOD

摘要

PURPOSE: A touch panel of a 5-wired electrode analogue resistor film method is provided to maintain a valid operation area having a sufficient straight property by separating a resistor chain of a touch panel of a 5-wired electrode system from new-formed voltage security pattern, extending a valid operation area of a sensor, and securing/changing a unit size and a voltage security pattern of the resistor chain. CONSTITUTION: A uniform resistor film(10) of a touch panel is formed on a base plate(12). A connection sheet is formed at the lower surface of a film using a transparent conductive film and combined on the resistor film(10) through the medium of an insulation frame at a predetermined interval. A resistor element(50) is arrayed for being overlapped with an adjacent unit according to units by making a predetermined formed unit(52) be formed as a discontinuously chain for exceeding an increasing rate of a surface area of a sensor, thereby supplying a linear output response by reducing a curve of equipotential lines according to the edge of the sensor. A voltage securing pattern(60) is arrayed for compensating a voltage deviation at an irregular interval by a detailed pattern through an etching of a surface of the resistor film(10) according to the inner edge of the resistor element(50) at a form completely separated from the resistor element(50).
