Abstract: Disclosed are a conductive film and a test component. A conductive film includes a supporting layer, a circuit layer and a protective layer. The supporting layer has a first surface and a second surface opposite to the first surface. The supporting layer supports the circuit layer. The circuit layer includes a first protruding part, a second protruding part and a connecting part. The first protruding part is disposed on the first surface. The second protruding part is disposed on the second surface. The connecting part is disposed between the first protruding part and the second protruding part. The first protruding part is connected to the second protruding part through the connecting part. The protective layer covers the first protruding part. The conductive film and the test component of the disclosed embodiments may have a buffering effect or increase the service life.

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.
