Abstract: A display device includes a display panel that has a plurality of gate lines and a plurality of data lines intersecting each other, a plurality of sensing lines that is formed in the display panel, a sensing driver that applies a sensing scan signal to the plurality of sensing lines and receives a predetermined electrical signal from the plurality of sensing lines corresponding to an external stimulus, and a demultiplexer that is provided between the sensing lines and the sensing driver and time-divides each sensing scan signal transmitted by the sensing driver to be sequentially applied to at least two sensing lines.

Abstract: A plurality of pixel parts is electrically connected to gate and source lines. Each of the pixel parts has a thin-film transistor (TFT) formed therein. A plurality of hall sensing parts is formed in the pixel parts. A plurality of hall sensing parts varies a reference current applied to the gate and the source lines by a magnetic member. The position detector is electrically connected to the gate lines and the source lines. The position detector detects a position of the magnetic member using the gate and source lines to which a varied current is applied. The plurality of hall sensing parts formed in the pixel parts detect the position of the magnetic member that approaches or contacts the screen of the display.

Abstract: A thin film transistor array panel includes a substrate including a display area and a peripheral area disposed at the outside of the display area, shield members formed in the peripheral area, gate lines formed in the display area and the peripheral area, a first insulating layer formed on the shield members and the gate lines, semiconductor layers formed on the first insulating layer, and data lines formed on the semiconductor layers and drain electrodes separated from the data lines.
