Abstract

The present disclosure provides a wearable display device, a belt buckle and a belt. The wearable display device includes a body; a display screen arranged on the body; a storage module configured to store data; and a controller configured to output a display signal in accordance with the data stored in the storage module, thereby to enable the display screen to display the display signal from the controller. According to the present disclosure, the wearable display device can display stationary or dynamic images, thereby to meet the user's individualized requirements.

First claim

1 . A wearable display device, comprising:
a body; a display screen arranged on the body; a storage module configured to store data; and a controller configured to output a display signal in accordance with the data stored in the storage module, thereby to enable the display screen to display the display signal output from the controller.

2 . The wearable display device according to claim 1 , further comprising: a power supply module configured to supply power to the controller, the storage module and the display screen; and
a light sensor configured to detect light intensity and generate a light sensing signal; wherein the controller comprises: a first control module configured to control the display screen to adjust its brightness in accordance with the light sensing signal from the light sensor.

3 . The wearable display device according to claim 2 , wherein the power supply module comprises a solar power supply module and a storage battery power supply module;
the controller further comprises a second control module configured to receive the light sensing signal from the light sensor, and control the solar power supply module to supply power to the controller and control the solar power supply module to charge the storage battery power supply module when the light sensing signal is greater than a predetermined value; and a third control module configured to receive the light sensing signal from the light sensor, and control the storage battery power supply module to supply power to the controller and control the solar power supply module to be charged when the light sensing signal is less than the predetermined value.

4 . The wearable display device according to claim 1 , further comprising a power supply module configured to supply power to the controller, the storage module and the display screen, and a distance sensor configured to detect a distance between an external occlusion and the body and generate a distance sensing signal; and
the controller further comprises: a fourth control module configured to control on and off states of the power supply module in accordance with the distance sensing signal from the distance sensor.

5 . The wearable display device according to claim 1 , wherein the display screen is a flexible screen protruding toward an outer side of the body and having a curved surface.

6 . The wearable display device according to claim 1 , wherein the display screen comprises a display surface, a back surface opposite to the display substrate, and a reflective layer arranged at a side of the back surface of the display screen.

7 . The wearable display device according to claim 1 , wherein the display screen comprises a transparent touch panel connected to the controller and having a touch function, and a display panel connected to the controller and having a display function, and the display panel is located below the transparent touch panel.

8 . A belt buckle, comprising the wearable display device according to claim 1 .

9 . A belt comprising:
the belt buckle according to claim 8 ; and a belt body; wherein a flexible touch module is arranged on the belt body in an extension direction of the belt body; a belt clip portion of the belt buckle for buckling the belt body is provided with a static contact configured to be in contact with the flexible touch module so as to generate a current; the belt body is provided with at least two electrodes configured to receive a current signal generated when the static contact is in contact with the flexible touch module, and the at least two electrodes are arranged at two ends of the flexible touch module, respectively; and the controller further comprises a data conversion module configured to convert the current signal received by the at least two electrodes into waistline data.

10 . The belt according to claim 9 , wherein the data conversion module comprises:
an analog-to-digital (A/D) converter configured to convert the current signal received by the at least two electrodes into a digital signal; an operation module configured to convert the digital signal into position information of a contact point where the static contact is in contact with the flexible touch module and acquire the waistline data in accordance with the position information; and a storage module configured to store the waistline data.
