Casio Computer has been granted a patent for an electronic device with two processors and two display units. The first processor can be set to normal, low power, or pause mode, controlling the first display unit to show the time. In pause mode, the first display unit is turned off and the second processor controls the second display unit to display the time. The second processor can also be set to normal or low power mode independently of the first processor.

Patent granted for an electronic device with dual processors and displays
A recently granted patent (Publication Number: US11774916B2) describes an electronic device with two processors and two display units. The first processor and second processor work together to perform display operations, including displaying the time. The first processor can be set to different modes: normal mode, low power mode, or pause mode, each with varying power consumption levels. In the normal or low power mode, the first processor controls the first display unit to display the time, while the second processor ensures that the second display unit does not display the time. In the pause mode, the first display unit is turned off, and the second processor controls the second display unit to display the time.
The second processor can also be set to two modes: second normal mode and second low power mode. The second processor's power consumption and operation frequency are lower than those of the first processor. Importantly, the second processor can be set to these modes independently of the first processor's mode. This means that the second processor can be in the second normal mode or second low power mode regardless of whether the first processor is in normal mode, low power mode, or pause mode.
Additionally, the patent describes a display control method for the electronic device. The method involves cooperative control by the first and second processors to perform display operations, including displaying the time. The first processor can be selectively set to normal mode, low power mode, or pause mode, with corresponding power consumption levels. In normal or low power mode, the first processor controls the first display unit to display the time, while the second processor prevents the second display unit from displaying the time. In pause mode, the first display unit is turned off, and the second processor controls the second display unit to display the time. The second processor can also be selectively set to second normal mode or second low power mode, independently of the first processor's mode.
The patent also mentions that the second processor operates with lower power consumption and operation frequency compared to the first processor. Furthermore, the second display unit is stacked on top of the first display unit. When the second display unit is not displaying the time, it can transmit the display content of the first display unit.
In summary, this patent describes an electronic device with two processors and two display units, allowing for flexible control of power consumption and display operations. The second processor operates with lower power consumption and can be set to different modes independently of the first processor. The second display unit can transmit the display content of the first display unit when not displaying the time.
