Abstract
The present disclosure belongs to the technical field of display, and provides an array substrate, a handwriting tablet, a tablet eraser, a handwriting tablet system and a method for erasing a pattern. The array substrate is provided with a handwriting area, and a peripheral area surrounding the handwriting area. The array substrate includes erasing electrodes, which are arranged in an array, and a driving circuit for driving the erasing electrodes, wherein the driving circuit is configured to load, under the irradiation of preset light, an erasing voltage to the erasing electrodes. The array substrate is further provided with an NFC coil, which is used for sending an NFC signal, wherein a sensing range of the NFC coil covers the handwriting area.
