Method, system, and related device for operating display device

A system for operating a display device, comprising a control device and a light tracking system;

• wherein,
• the control device is configured to
• emit directional light to the display device when detecting a key thereof is pressed, the directional light being reflected from the display device and forming a first reflected light,
• receive said first reflected light and collect data of intensity of said first reflected light, and
• transmit the data of intensity of the first reflected light and information of the pressed key to the light tracking system;
• the light tracking system is configured to:
• preconfigure a table of various data of intensity of reflected light on the light tracking system when a control device is at various different distances from the display device, wherein said data of intensity of reflected light in said table correspond to coordinate positions on the display device, and said reflected light corresponds to a directional light that is sent from the control device to a control area on the display device and reflected from the display device;
• match a corresponding coordinate position on the display device from said preconfigured table of various data of intensity of reflected light according to the data of intensity of said first reflected light and a current distance between the control device and the display device;
• and
• execute a corresponding operation on an area corresponding to the coordinate position of the display device in conjunction with the information of the pressed key, and reflect an operation result on the display device.

A light tracking system for operating a display device, comprising a processor and a storage device for storing computer executable instructions, wherein,

• a core control module, performed by the processor, is configured to manage, control and schedule other modules in the light tracking system;
• an automatic configuration module, performed by the processor, is configured to configure a table of various data of intensity of reflected light on the light tracking system when a control device is at various different distances from the display device, wherein said data of intensity of reflected light in said table correspond to coordinate positions on the display device, and the reflected light corresponds to a directional light that is sent from the control device to a control area on the display device and reflected from the display device;
• wherein the control device emits the directional light to the display device when detecting a key thereof is pressed and the directional light is reflected from the display device and forms a first reflected light, the control device receives said first reflected light and collects data of intensity of said first reflected light and transmits the data of intensity of the first reflected light and information of the pressed key to the light tracking system;
• a data reception module, performed by the processor, is configured to receive said data of intensity of said first reflected light and information of the pressed key transmitted by the control device;
• and
• a data processing module, performed by the processor, is configured to match a corresponding coordinate position on the display device from said table of various data of intensity of reflected light according to the data of intensity of said first reflected light and a current distance between the control device and the display device, execute a corresponding operation on an area corresponding to the coordinate position of the display device in conjunction with information of the pressed key on the control device, and display an operation result on the display device.
