摘要： During booting of a display panel and a light source, low power supply for electronic circuits is provided to the display panel. Then, the display panel is set by R/W commands. Then, high power supply for liquid crystal transition is provided to the display panel. Then, the display panel is discharged for removing residual electronic charges. Then, the light source is turned on for emitting light to the display panel. On the contrary, during shut down, the light source is turned off and then the display panel is discharged. Then, application of high power supply is stopped. Then, the display panel is set by R/W commands. Then, application of low power supply is stopped.
