Abstract

Disclosed is a display device with integrated touch screen. The display device includes a plurality of receiving electrodes formed in a block type and in parallel with a plurality of data lines, a driving electrode group configured to include a plurality of driving electrodes that are respectively disposed between the plurality of receiving electrodes, a plurality of receiving electrode lines respectively connected to the plurality of receiving electrodes, a plurality of driving electrode lines configured to extend from the respective driving electrodes to the first non-display area, a driving IC configured to apply a common voltage or a driving pulse to the plurality of receiving electrode lines and the plurality of driving electrode lines, and a plurality of driving dummy lines formed at a plurality of pixels, covered by a corresponding driving electrode, in a direction parallel to the plurality of driving electrode lines.

Description

technical field [0001] The present invention relates to display devices, and more particularly, to display devices with integrated built-in touch screens Background technique [0002] With the development of various portable electronic devices such as mobile terminals and notebook computers, demand for flat panel display (FPD) devices applied to portable electronic devices is increasing. Among such FPD devices, application fields of liquid crystal display (LCD) devices are expanding due to advanced manufacturing techniques, easy-to-drive drivers, high-quality images, and large screens. [0003] Instead of an input device such as a mouse or a keyboard conventionally applied to the LCD device, a touch screen enabling a user to directly input information with a finger or a pen is recently applied as the input device of the LCD device. [0004] In particular, in applying a touch screen to an LCD device used in a portable terminal such as a smartphone, in order to become slim, a...
