The control unit is used for controlling the cutting mechanism to cut the print medium when the sensor senses the recognition mark.

Abstract: A light emitting module and a display device comprising the light emitting module are provided. The light emitting module comprises an excitation light source, a phosphor wheel and a driving circuit. The excitation light source is configured to generate an excitation light. The phosphor wheel has a plurality of color segments and rotates at a period so that each of the color segments sequentially receives the excitation light to generate a color light. The driving circuit is electrically connected to the excitation light source and the phosphor wheel. The driving circuit is configured to provide a driving current to the excitation light source, and changes the driving current in accordance with each of the color segments receiving the excitation light so as to adjust an energy conversion efficiency of each of the color segments for generating the color light.

Abstract: A ribbon includes at least one dye region, at least one separating region and at least one recognition dye region. Each of the dye regions includes a plurality of dye zones. The separating region is formed on a side of the dye region for separating different dye regions. The recognition dye region is formed on the separating region or formed within a range covered by the corresponding dye region. A thermal print head of a thermal sublimation printer transfers the dye region and the recognition dye region of the ribbon onto a print medium, so as to form an image area and a recognition mark on the print medium, correspondingly. A cutting mechanism of the thermal sublimation printer is used for cutting the print medium when a sensor of the thermal sublimation printer senses the recognition mark.
