<p>The invention relates to an electronic information board, a control unit (62) of the information board and a temperature-based control method of the information board. In the information board according to the invention, the operating voltages (630, 640, 650, 660) required by it are generated in a centralized manner in the power supply (623) of the control unit (62). The control unit also includes a switching unit (620), which switches the input voltage of the power supply (623) on or off on the basis of the temperature measured inside the information board.</p> |
