<P>PROBLEM TO BE SOLVED: To provide a display device, wherein power consumption of the display device is reduced and processing time for display rewriting is short and response is good. <P>SOLUTION: In a step S104, a first clock PCK is supplied to an arithmetic processing section 104, and a generated second clock MCK is converted by a clock conversion section 105 to generate a converted clock CCK. The converted clock CCK is supplied to a clock supply block 107. RAM 15 in each peripheral device performs information writing operation periodically in synchronization with the converted clock. In a step S105, the arithmetic processing section 104 executes a control program in synchronization with the first clock PCK. In a step S109, supply of the first clock PCK to the arithmetic processing section 104 is stopped, ending the execution of the control program. During this time, the converted clock is supplied to the each peripheral device, and power supply to the RAM 15 is continued. <P>COPYRIGHT: (C)2010,JPO&INPIT |
