Title:
DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/151048
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a display device with which it is possible to appropriately detect the proximity of an object-to-be-detected. Provided is a display device, comprising, in a display substrate 1 which is provided with a display region R: a proximity sensor 40 which has been positioned in a region further toward the external side than the display region R; and a terminal part 50 to which the proximity sensor 40 has been connected. The proximity sensor 40 comprises a plurality of conductors 40a and 40b which have been positioned so as to surround the perimeter of the display region R while being separated from each other. The plurality of conductors 40a and 40b each have one end part thereof connected to the terminal part 50, and a prescribed voltage is applied thereto via the terminal part 50 so that a capacitance is formed with an object-to-be-detected. The proximity sensor 40 further comprises capacitance supplying regions 401a, 401b which are disposed in the vicinity of a separation region D whereat the plurality of conductors 40a and 40b are separated from each other, and which compensate for the capacitance formed with the object-to-be-detected in the separation region D.
