Abstract

Provided is a display device. The display device includes a control component, and the control component is configured to control a display component to operate; and control, in response to receiving a first control instruction, at least one of a near-field communication component and the display component such that a signal-sending period of the near-field communication component falls within an image-holding period of the display component, wherein the near-field communication component is configured to send a signal during the signal-sending period.

First claim

What is claimed is:

1. A display device, comprising a control component, a near-field communication component, and a display component, wherein the near-field communication component and the display component are both electrically connected to the control component, and the control component is configured to:
control the display component to operate; and
control, in response to receiving a first control instruction, at least one of the near-field communication component and the display component such that a signal-sending period of the near-field communication component falls within an image-holding period of the display component, wherein the near-field communication component is configured to send a signal during the signal-sending period;
the control component is configured to:
send a first control signal to the near-field communication component and send a second control signal to the display component;
wherein the first control signal comprises a target length of the signal-sending period a target polling cycle, and a target position of the signal-sending period in each polling cycle, the target length being less than or equal to a length of the image-holding period of the display component operating at a target refresh cycle, the target polling cycle being an integer multiple of the target refresh cycle, and the target position being identical to a position of the image-holding period in one refresh cycle of the display component, and the second control signal instructs the display component to operate at the target refresh cycle.

2. The display device according to claim 1 , wherein the display component comprises a display substrate and a heat dissipation layer disposed on a back of the display substrate; and
the near-field communication component comprises a first controller and a coil, the first controller being electrically connected to the coil and the coil being disposed in the heat dissipation layer.

3. The display device according to claim 2 , wherein the heat dissipation layer comprises a substrate and a metal layer disposed on the substrate, and the coil of the near-field communication component and the metal layer are of a same layer structure and disposed in a same layer.

4. The display device according to claim 3 , wherein a distance between the coil and the metal layer ranges from 1 mm to 50 mm.

5. The display device according to claim 1 , wherein the display component comprises a display substrate provided with a data line; and
the near-field communication component comprises a first controller and a coil, wherein the first controller is electrically connected to the coil, and an orthographic projection of the coil onto a first surface is at least partially overlapped with an orthographic projection of the data line onto the first surface, the first surface being a surface where a light-emergent surface of the display substrate is disposed.

6. A control method of a display device, applicable to the display device comprising a near-field communication component and a display component, wherein the method comprises:
controlling the display component to operate; and
controlling, in response to receiving a first control instruction, at least one of the near-field communication component and the display component such that a signal-sending period of the near-field communication component falls within an image-holding period of the display component, wherein the near-field communication component is configured to send a signal during the signal-sending period;
the near-field communication component is configured to cycle into the signal-sending period and a monitoring period; and the controlling, in response to receiving the first control instruction, at least one of the near-field communication component and the display component such that the signal-sending period of the near-field communication component falls within the image-holding period of the display component comprises:
sending, in response to receiving the first control instruction, a control signal to the at least one of the near-field communication component and the display component such that a polling cycle is an integer multiple of a refresh cycle of the display component and the signal-sending period falls within the image-holding period of the display component, wherein the polling cycle is a period during which the near-field communication component cycles into the signal-sending period and the monitoring period.

7. The control method according to claim 6 , wherein sending the control signal to the at least one of the near-field communication component and the display component comprises:
sending a first control signal to the near-field communication component, wherein the first control signal comprises a target length of the signal-sending period, a target polling cycle, and a target position of the signal-sending period in each polling cycle, the target length being less than or equal to a length of a current image-holding period of the display component, the target polling cycle being an integer multiple of a current refresh cycle of the display component, and the target position being identical to a position of the image-holding period in one refresh cycle of the display component.

8. The control method according to claim 7 , wherein the first control instruction instructs the near-field communication component to enter a card reading mode, and the near-field communication component is configured to cycle into the signal-sending period and the monitoring period in the card reading mode.

9. The control method according to claim 6 , wherein sending the control signal to the at least one of the near-field communication component and the display component comprises:
sending a second control signal to the display component, wherein the second control signal instructs the display component to operate at a target refresh cycle such that the signal-sending period falls within the image-holding period of the display component.

10. The control method according to claim 9 , further comprising:
controlling, in response to receiving the second control instruction, the near-field communication component to stop entering the signal-sending period, and controlling the display component to operate at a first refresh cycle, wherein the first refresh cycle is less than the target refresh cycle.

11. The control method according to claim 10 , wherein upon controlling, in response to receiving the first control instruction, at least one of the near-field communication component and the display component such that the signal-sending period of the near-field communication component falls within the image-holding period of the display component, the method further comprises:
controlling, in response to receiving card-removing information sent by the near-field communication component, the least one of the near-field communication component and the display component such that the signal-sending period of the near-field communication component falls within the image-holding period of the display component, wherein the card-removing information indicates that a card read by the near-field communication component has been removed.

12. The control method according to claim 6 , wherein sending the control signal to the at least one of the near-field communication component and the display component comprises:
sending a first control signal to the near-field communication component and sending a second control signal to the display component;
wherein the first control signal comprises a target length of the signal-sending period, a target polling cycle, and a target position of the signal-sending period in each p
