And step 203, controlling the state of the terminal equipment according to the current state of the display.
In this embodiment, the terminal device controls relevant firmware in the terminal device to be in a corresponding state according to the determined current state of the display, and the relevant firmware may include, for example, a GPU in the terminal device, a power supply, other VR chips in a motherboard, and the like.
Optionally, the end device includes a CPLD and a GPU, and the CPLD generates a control instruction according to the current state of the display, and sends the control instruction to the GPU to control the state of the GPU.
In this embodiment, the CPLD is used as a processor in the terminal device, receives a state signal output by the display through the control circuit, determines a current state of the display according to a signal waveform of the state signal, generates a control instruction for controlling the related firmware of the terminal device according to the current state of the display after the CPLD determines the current state of the display, and transmits the control instruction to the related firmware respectively to control the related firmware to be in a corresponding state, where the related firmware is taken as a GPU for example.
Exemplarily, the CPLD determines that the current state of the display is a power-on state, generates a power-on control instruction, transmits the power-on control instruction to related firmware including the GPU, and controls the GPU and other related firmware to be powered on; the CPLD determines that the current state of the display is a power-off state, generates a power-off control instruction, transmits the power-off control instruction to relevant firmware including the GPU, and controls the GPU and other relevant firmware to power off; the CPLD determines that the current state of the display is the sleep state, generates a sleep control instruction, transmits the sleep control instruction to the relevant firmware including the GPU, and controls the GPU and the other relevant firmware to enter the sleep state.
In the device control method, the terminal device acquires a state signal output by a control circuit of a display connected with the terminal device, acquires a signal waveform of the state signal, determines the current state of the display according to the signal waveform, and controls the state of the terminal device according to the current state of the display. In this scheme, the terminal device may determine the current state of the display based on a waveform corresponding to the state signal output by the control circuit of the display, so as to control the terminal device to be in a corresponding state based on the current state of the display. Because the state signal that the control circuit of display exported all can be exported for general display, consequently, need not carry out special customization to the display, the suitability is strong, has reduced the software and hardware cost of display.
After receiving the status signal, the terminal device may determine the current state of the display indicated by the status signal according to the waveform of the status signal, and in an alternative embodiment, the determining the current state of the display according to the waveform of the status signal includes:
determining the current state of the display corresponding to the signal waveform of the state signal according to the mapping relation between the signal waveform and the state of the display; the display state comprises any one of a power-on state, a power-off state and a dormant state.
Alternatively, the mapping relationship between the signal waveform and the display state may be preset, and for example, the mapping relationship may be stored in the mapping relationship between the signal waveform characteristic and a display state code, where the display state code is used to indicate the display state, for example, S0 indicates that the display state is a power-on state, S3 indicates that the display state is a sleep state, and S5 indicates that the display state is a power-off state. Optionally, the state of the display corresponding to the signal waveform a is an S0 power-on state; the state of the display corresponding to the signal waveform B is the S3 sleep state, and the state of the display corresponding to the signal waveform C is the S5 power-down state. Alternatively, the mapping relationship may be stored in a storage space designated by the terminal device, and the terminal device obtains the mapping relationship from the storage space before executing the above steps.

Step 302, acquiring the signal waveform of the processed status signal, and determining the current status of the display corresponding to the signal waveform of the status signal according to the mapping relationship between the signal waveform and the status of the display.
In this embodiment, the terminal device determines the current state of the display corresponding to the signal waveform according to the signal waveform corresponding to the state signal after the voltage conversion processing, and the determination method is similar to that in the above embodiment, which is not described herein again.
In this embodiment, the voltage conversion processing is performed on the status signal output by the control circuit of the display, so that the terminal device can receive the status signal in an effective and safe environment, and perform subsequent operations based on the status signal, thereby ensuring the validity of the status signal.
