Display device and input device

摘要

Disclosed are a display device and an input device. The display device includes: gate and data lines arranged to cross each other and to define a pixel region; a pixel electrode disposed on the pixel region; a sensing element disposed on the pixel region; and a switching element configured to selectively connect the data line with any one of the pixel electrode and sensing element. Such a display device according to an embodiment allows both of a scan signal for the display of an image and an externally input signal to be transferred through the data line. Therefore, the display device according to an embodiment can display an image and input an external signal such as a touch or others, using a simplified configuration.

1. A display device comprising:
gate and data lines arranged to cross each other and to define a pixel region; a pixel electrode disposed on the pixel region; a sensing element disposed on the pixel region; a switching element configured to selectively connect a respective data line with any one of the pixel electrode and sensing element, wherein the switch element includes:
a first switch configured to perform any one of a connection and a disconnection between the pixel electrode and the respective data line, anda second switch configured to perform any one of a connection and a disconnection between the sensing element and the respective data line; and a switching signal line disposed parallel to the respective data line, wherein the first switch includes:
a first thin film transistor configured to be driven by a first switching signal supplied from a respective gate line, anda second thin film transistor configured to be driven by a second switching signal supplied from the switching signal line, and wherein the second switch includes:
a third thin film transistor configured to be driven by the first switching signal supplied from the respective gate line, anda fourth thin film transistor configured to be driven by the second switching signal supplied from the switching signal line, andwherein the second thin film transistor and the fourth thin film transistor are opposite polarity types of transistors to each other so that when either of the second and fourth thin film transistors is turned on, the other is turned off.
