Abstract
The present invention relates to a display device comprising a battery (6) used as the power supply in standby mode and a standby mode microcontroller (3) which controls the elements used in standby mode by measuring the current drawn from the battery (6) and the battery voltage (Vbat), and in which device, the power drawn from the mains supply in standby mode is zero.
Claims17
A display device, which is operational in normal operation mode, and in standby mode and active standby mode, wherein it consumes low energy, the display device comprising
- a main microprocessor controlling a circuit and its elements, a standby mode microprocessor, a receiver that receives infrared (IR) signals sent by a remote control and transmits them to the standby mode microprocessor, a battery used as a power supply in standby mode, a DC-DC converter by which standby mode voltage (Vstby) is obtained from the battery voltage (Vbat);
- characterized by
- the standby mode microprocessor which, in standby mode, constantly measures a value of the battery voltage (Vbat) and a value of current drawn from the battery, and according to changes in these values, carries out control of supply to the receiver and an adjustment of a gain value of the DC-DC converter.
