Parameter No Parameter
Description
This command turns off sleep mode.
In this mode e.g. the DC/DC converter is enabled, Internal oscillator is started, and panel scanning is started.
X = Don’t care
Restriction
This command has no effect when module is already in sleep out mode. Sleep Out Mode can only be left by the Sleep In
Command (10h). It will be necessary to wait 5msec before sending next command, this is to allow time for the supply voltages
and clock circuits stabilize. The display module loads all display supplier’s factory default values to the registers during this
5msec and there cannot be any abnormal visual effect on the display image if factory default and register values are same
when this load is done and when the display module is already Sleep Out –mode. The display module is doing self-diagnostic
functions during this 5msec. It will be necessary to wait 120msec after sending Sleep In command (when in Sleep Out mode)
before Sleep Out command can be sent.
