下面对于本发明应用于可信终端中开放环境和可信环境之间相互进行切换调用时的一个具体实施例进行说明。
图1是表示本发明的一个实施例的系统间显示画面切换方法。
在该实施例中,A系统是开放系统,B系统是可信系统。
下面参照图1对于该实施例的各步骤进行具体说明。
如图1所示,步骤S101:当A系统内应用处理完成,需要调用B系统。
步骤S102:A系统根据当前自身显示情况,为B系统生成用于在切换间隔时间中显示的切换间隔信息。
步骤103:A系统发送切换指令和为B系统准备的切换间隔信息到B系统。
步骤104:在切换到B系统后,B系统首先显示收到的切换间隔用信息,然后B系统启动其他模块和应用的初始化。
步骤105:B系统正常初始化完成后,刷新系统自身的显示内容的到显存,替换掉正在显示的切换间隔信息。
步骤106:B系统的应用在处理完成后,返回结果到A系统。
步骤107:B系统为A系统生成用于在切换间隔时间内显示的切换间隔信息,或者也可以B系统从其内存中调取用于在切换间隔时间内显示的切换间隔信息。
