  • Patent number: 10613664
    Abstract: Disclosed is a display device with a built-in touch screen. The display device includes a gate electrode and a pixel electrode on a substrate, an activation layer and a sensing contact portion, a source electrode and a drain electrode, and a gate insulation layer provided between the gate electrode and the activation layer and between the pixel electrode and the sensing contact portion. Thereby, it is possible to reduce the number of data lines arranged in the display panel. Also disclosed is a method of fabricating a display device with a built-in touch screen. The method includes forming a first gate electrode and a pixel electrode according to a first mask process, and forming an activation layer, a source electrode, a drain electrode, and a touch sensing line according to a second mask process. Thereby, it is possible to reduce the number of mask processes.

  • Patent number: 10001859
    Abstract: A touch-integrated display panel includes a substrate, a plurality of first and second pixels, a touch electrode, and a shield electrode. The substrate has an active area and a non-active area outside of the active area. The plurality of first pixels are disposed in the active area, and the plurality of second pixels are disposed in the non-active area. The touch electrode is formed by electrically connecting the common voltage electrodes of a group of first pixels among the plurality of first pixels. The shield electrode is formed by electrically connecting the common voltage electrodes of the plurality of second pixels. The shield electrode is disposed to surround the active area.

  • Patent number: 9316859
    Abstract: A liquid crystal display device and a method for manufacturing the same are disclosed. The liquid crystal display device comprises first and second substrates facing each other; a transparent conductive film formed on one surface of the first substrate, absorbing charges of electro static discharge (ESD); a black matrix including a first black matrix formed on a corner of the other surface of the first substrate and end portions spaced apart from one end of the first black matrix at a predetermined interval for insulation; a ground electrode formed on one surface of the second substrate; and a connection portion connecting the transparent conductive film with the ground electrode, and extending over the end portions.
