Patent ID: 8605038

Claim:
A touch screen panel type liquid crystal display, comprising: an upper substrate comprising a first insulating substrate, a transparent conductive layer on the first insulating substrate, and a first polarizer on the transparent conductive layer, the transparent conductive layer configured to receive a position detection current to form a capacitance with a position signal input unit, and the first polarizer configured to serve as a dielectric between the transparent conductive layer and the position signal input unit; a lower substrate comprising a second insulating substrate, a second polarizer on the second insulating substrate, and a thin film transistor layer, the second insulating substrate being between the thin film transistor layer and the second polarizer; a liquid crystal layer between the upper substrate and the lower substrate; a signal detection unit configured to measure first and second voltages at first and second side portions, respectively, of the transparent conductive layer, to thereby detect a contact position of the position signal input unit on the first polarizer based on a change in electrical load at the contact position through a conversion circuit caused by an absorption of electrical charges by the position signal input unit; and a linear pattern at one surface of the transparent conductive layer to uniformly distribute an electric field on the first polarizer, wherein the linear pattern is configured to receive a voltage when a position detection signal is applied to the transparent conductive layer.
