<P>PROBLEM TO BE SOLVED: To provide a display method for preventing occurrence of display irregularity of a display device having memory performance, a display device and a display system. <P>SOLUTION: A CPU 111 of an electronic shelf label 1 stores plotting information received from an electronic shelf label server through an RF 116 in a RAM 113. Then, it transmits an on-signal to an LCD power supply circuit 13 through an I/O 117, drives a COMMON driver 17 and a SEGMENT driver 18 to display the plotting information on a cholesteric LCD 16, and then transmits an off-signal to the LCD power supply circuit 13 through the I/O 117, and stops drive by the COMMON driver 17 and the SEGMENT driver 18. The CPU 111 monitors temperature informed from a temperature sensor 14 through an ADC 115, reads out the plotting information from the RAM 113 if variation of temperature exceeds the predetermined one, and displays the read-out plotting information on the cholesteric LCD 16 again. <P>COPYRIGHT: (C)2010,JPO&INPIT |
