Grating assembly, display device, control method thereof, and storage medium

Abstract

The present application relates to a grating assembly, a display device, a control method thereof and a storage medium, in the field of display technology. The grating assembly comprises: a first substrate and a second substrate disposed opposite to each other, and a liquid crystal layer disposed between the first substrate and the second substrate. The first substrate is provided with a power supply electrode on a side adjacent to the liquid crystal layer, and the second substrate is provided with k strip electrodes on a side adjacent to the liquid crystal layer. The k strip electrodes are connected to form a coil. The power supply electrode is configured to receive a first electrical signal, each of the k strip electrodes is configured to receive a second electrical signal, liquid crystals between the power supply electrode and each of the strip electrodes are configured to deflect to form a grating structure after the power supply electrode receives the first electrical signal and each of the strip electrodes receives the second electrical signal, and at least two of the k strip electrodes are further configured to receive a third electrical signal so that the coil formed by the k strip electrodes generates a magnetic field. The present application solves the problem that the relatively high cost of setting up the NFC antenna and helps to reduce the cost.
