Abstract

A display apparatus for reducing moire and a method of driving the same are provided. The display apparatus includes a pixel pattern in which pixels are periodically arranged, and a first sensor disposed on the display panel and including an electrode pattern in which a plurality of electrodes are periodically arranged. An electrode pitch of the electrode pattern is smaller than a pixel pitch of the pixel pattern, an electrode arrangement direction of the electrode pattern forms an angle with respect to a pixel arrangement direction of the pixel pattern, and at least two adjacent electrodes among the plurality of electrodes are connected to each other and configured to send and receive signals through one line.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2017-0099608 filed in the Korean Intellectual Property Office on Aug. 7, 2017, the entire disclosure of which is hereby incorporated by reference. technical field [0003] Devices and methods according to example embodiments relate to a display device for reducing moiré and a driving method thereof. Background technique [0004] There is an increasing need for personal authentication using intrinsic features such as fingerprints, voice, face, hand and iris, which are used in banking devices, access controllers, mobile devices and laptops. According to the widespread availability of mobile devices such as smartphones, tablet personal computers (PCs) and smart watches in recent years, fingerprint recognition devices for personal authentication are being adopted to protect a large amount of security information stored in such mobile devices.
