  • Color control of trace of display device control pen on display device
    Patent number: 10139933
    Abstract: A display device control pen comprises a pen body and at least one detachable accessory. The detachable accessory comprises an electronic component. The pen body is detachably assembled with the detachable accessory. The pen body comprises at least one variable-voltage circuit, a signal generating unit and a signal transmitter. When the detachable accessory is assembled to the pen body, the electronic component is electrically connected to the variable-voltage circuit and varies a voltage value of the variable-voltage circuit. The signal generating unit is coupled to the variable-voltage circuit and generates a color signal based on the varied voltage value. The signal transmitter is coupled to the signal generating unit and transmits the color signal to the display device, such that the display device displays a color on a trace formed by the pen body according to the color signal.
