BATTERY OPERATED DEVICE WITH DISPLAY |
摘要 |
A portable electronic device (40) comprises a display module (42) and a battery unit (44). The device has at least one further analogue input or output interface (50,52,54) (in addition to the display). The display module includes a voltage converter (48) for providing at least one voltage exceeding the battery unit voltage, and an output from the voltage converter (48) of the display module is provided to a circuit (50a, 52a, 54a) associated with the at least one further analogue input or output interface. This enables a reduction in cost and volume of the device by providing a highly integrated solution, in which a voltage converter within a display module is used also for circuitry of another interface or interfaces. |
