Abstract

The invention provides a substrate, a display device, a driving method thereof, and a touch display system, which relate to the field of touch technology, and can make the use of the touch function of a large-size display device not limited by size. The display device includes a substrate, the substrate includes a substrate, and the substrate includes a main touch area; the main touch area is provided with a touch structure, and the touch structure includes first touch electrodes and second touch electrodes that are insulated from each other and arranged crosswise. control electrodes; a first dummy electrode is also arranged between adjacent first touch electrodes, and the first dummy electrode is connected to its adjacent first touch electrode; a second dummy electrode is also arranged between adjacent second touch electrodes. electrode, and the second dummy electrode is connected to its adjacent second touch electrode; wherein, the material of the first dummy electrode and the second dummy electrode is a photoresistive material sensitive to light of a specific wavelength band, and the first dummy electrode and the second dummy electrode All dummy electrodes are transparent.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a substrate, a display device and a driving method thereof, and a touch display system. Background technique [0002] At present, small-sized touch screens have been widely used in electronic products such as smart phones, tablet computers, and televisions. Wherein, the small-size touch screen is generally based on contact touch, such as finger, pen and screen contact touch, to realize the recognition of the touch position. [0003] With the popularization of large-size display screens, especially for business, teaching and other fields, there is a greater demand for large-size display screens, but limited by the size of the display screen, the application of contact touch on large-size It brings a lot of inconvenience to users, so the application of integrating touch functions in large-size displays is greatly limited. Contents of the invention [0004] Embodiments of...
