A method, a system, and related equipment for operating display equipment are provided, comprising the following steps: control equipment launches orientation light to the display equipment when detecting a button thereof is pressed down, and sends the collected intensity data of the first reflected light and the button information to a light tracking system; the light tracking system matches a corresponding coordinate position according to the received first reflected light intensity and the known distance between the control equipment and the display equipment, the coordinate position is matched from the preset reflected light intensity corresponding to the distances between the coordinate positions of directional points on the control equipment and display equipment under the distance, combining the corresponding coordinate position with the button information; and the light tracking system executes relative operation on the relative area of the display equipment corresponding to the coordinate position, and reflects the operation result on the display equipment. Users can operate smart televisions with computer interfaces in a simple, visual, and conventional way easily by adopting the method, system and related equipment with relatively low cost..
