PURPOSE:To reduce the execution time for display control as much as possible while reducing the power consumption. CONSTITUTION:Display data are outputted from the CPU 22 exclusive for a display part in series and held by the shift register 35 of a dynamic driving display part 31 and the shift register 45 of a static driving display part 32. Some of LED display elements 40 are dynamically driven by a segment driver 37 and a source driver 38 by using the data held in the shift register 35 and the remaining LED display elements 40 are statically driven by using the data held in the shift register 45. |
