Abstract

提供了一种激光投影设备及其开机方法，激光投影设备中的电源（10）用于在显示组件（40）显示目标图像，且音频播放组件（30）播放目标音频的过程中，响应于下电指令，停止为显示驱动电路（20）供电，以及响应于上电指令，为显示驱动电路（20）供电。显示驱动电路（20）用于接收第一图像信号，并响应于第一图像信号控制显示组件（40）显示备选图像，以及接收第二图像信号，并响应于第二图像信号控制显示组件（40）显示目标图像。音频播放组件（30）用于接收并播放目标音频。由于在显示组件（40）处于开启状态之前，音频播放组件（30）并不会接收到音频，由此避免出现显示组件（40）还未开启，而音频播放组件（30）已经播放音频的情况，确保了播放的音频和显示的图像的同步。
