Problems solved by technology
[0002] According to different working principles, touch screens can be divided into resistive touch screens, capacitive touch screens, and electromagnetic touch screens. Resistive touch screens and capacitive touch screens can be directly operated by hand, but it is difficult to accurately distinguish between hand and pen touches. Therefore, electromagnetic touch screens came into being.

The invention discloses an array substrate and a display device. The array substrate includes a first thin film transistor and a second thin film transistor located on a base substrate; a plurality of ones located on the first film layer and located close to the base substrate of the first thin film transistor The first magnetic induction structure on the side; the vertical projection of the first active layer of the first thin film transistor on the substrate is located within the vertical projection of the first magnetic induction structure on the substrate; multiple and first magnetic induction structures The first patterned structure arranged on the same layer and located on the side of the second thin film transistor close to the substrate; the vertical projection of the second active layer of the second thin film transistor on the substrate is located on the substrate of the first patterned structure within the vertical projection on the substrate. Through the technical solution of the present invention, the difference between the position gap without the first magnetic induction structure and the position gap with the first magnetic induction structure is made up, the problem that the gap difference affects the conductive characteristics of the active layer of the thin film transistor is improved, and the The display uniformity of the display device.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to an array substrate and a display device. Background technique [0002] According to different working principles, touch screens can be divided into resistive touch screens, capacitive touch screens, and electromagnetic touch screens. Resistive touch screens and capacitive touch screens can be directly operated by hand, but it is difficult to accurately distinguish between hand and pen touches, so electromagnetic touch screens emerged as the times require. [0003] The electromagnetic touch screen is generally provided with a magnetic induction coil, and the electromagnetic pen is provided with a resonant circuit. The electromagnetic pen moves on the electromagnetic touch screen, and the resonant circuit in the electromagnetic pen is excited by the electromagnetic wave sent by the magnetic induction coil to send out an electromagnetic signal. The receiv...
