The following describes a flow of the display device entering the STR standby state from the power-on state and a flow of the display device entering the power-on state from the STR standby state, taking an STR (Suspend To RAM, also called memory standby mode) standby state as an example:

for example, a user may input a standby instruction to the display device in the power-on state by pressing a power key on the control apparatus, and after receiving the standby instruction, the display device stores the hardware operating state information into a memory (e.g., RAM), releases the hardware resources (e.g., a display, a hard disk, an external device, etc.) in use, and freezes a process; the PM module controls the power supply circuit to power down other hardware except the RAM and the MCU, namely the power supply circuit is controlled to only keep supplying power to the RAM and the MCU; and transmitting the off-screen broadcast to turn off the display. At this point, the display device enters the STR standby state. When the display device is in an STR standby state, the power consumption of the whole machine can be reduced.

Further, for example, a user may input a power start instruction from standby to startup to the display device in the STR standby state by pressing a power key on the control device, and when the display device receives the power start instruction, read hardware operating state information from the memory, and perform hardware initialization based on the read hardware operating state information; the PM module controls the power supply circuit to supply power to each hardware and starts an operating system program to recover to a state before suspension; and sending a bright screen broadcast to cause the display to light. At this point, the display device enters a power-on state. Through the processing, the waiting time for the display equipment to enter the startup state from the standby state can be saved, and the startup speed is improved.
