Referring to fig. 1, fig. 1 is a flowchart of an image data transmission method according to an embodiment of the present disclosure.
The specific steps may include:
s101: if an interrupt signal generated when the target screen device is connected to the mainboard is received, sending a parameter acquisition instruction to the target screen device through the NFC chip of the mainboard;
the present embodiment may be applied to a processing chip in a motherboard, where the motherboard may be a motherboard of an electronic device; as a possible embodiment, the main board may be a generic name of other devices in the electronic apparatus besides the screen device. The electronic devices include, but are not limited to, a mobile phone, a tablet computer, a smart bracelet, a smart watch, and the like. The main board further includes a main board NFC (Near Field Communication) chip, and the main board NFC chip is used for transmitting data with the screen device.
The mainboard and the target screen device can be provided with magnetic attraction contacts, the target screen device is connected with the mainboard through the magnetic attraction contacts, and when the target screen device is correctly installed on the mainboard, the magnetic attraction contacts can generate interrupt signals and send the interrupt signals to a processing chip of the mainboard. When an interrupt signal generated when the target screen device is connected to the motherboard is received, it can be stated that a new screen (i.e., the target screen device) is connected to the motherboard at this time.
It can be understood that, before receiving an interrupt signal generated when the target screen device is connected to the motherboard, there may be an operation of disconnecting the original screen device from the motherboard, and after the original screen device is disconnected from the motherboard, the processing chip of the motherboard may enter a sleep state so as to reduce power consumption; accordingly, after receiving an interrupt signal generated when the target screen device is connected to the motherboard, the processing chip of the motherboard can be woken up to enter a normal operating state.
After detecting that the target screen device is connected to the motherboard, the embodiment sends a parameter acquisition instruction to the target screen device through the motherboard NFC chip. Specifically, the target screen device may include a screen NFC chip and a screen IC chip, and after the motherboard NFC chip sends a parameter acquisition instruction to the screen NFC chip, the screen NFC chip parses the parameter acquisition instruction and transmits a data acquisition request to the screen IC chip, so that the screen IC chip returns a screen parameter to the motherboard NFC chip through the screen NFC chip.
S102: receiving screen parameters returned by the target screen device through the NFC chip of the mainboard, and determining target resolution according to the screen parameters;
the mainboard NFC chip can analyze the data packet transmitted by the target screen device to obtain the screen parameters, and returns the screen parameters to the processing chip of the mainboard. The main board NFC chip may also directly return the data packet transmitted by the target screen device to the processing chip, so that the processing chip analyzes the data packet to obtain the screen parameter of the target screen device.
The screen parameter may include Extended Display Identification Data (EDID) of the target screen device, and the present embodiment may determine the target resolution corresponding to the target screen device according to a corresponding relationship between the screen parameter and the resolution. As a possible implementation manner, the present embodiment may determine the screen model of the target screen device according to the screen parameters, and query the target resolution of the target screen device according to the screen model.

As a possible implementation manner, after stopping sending the image data, the processing chip may further send a reset instruction to the motherboard NFC chip, so as to initialize the motherboard NFC chip, and reduce power consumption. In daily use, a screen of an electronic device can cause damage to a circuit of the screen under the conditions of impact, water inflow and the like. However, since a part of other devices is added to the inside of the device screen in the related art, the device screen needs to be replaced together during replacement, which results in high cost for replacing the screen.

s203: sending next frame image data of the target resolution to the target screen device through the mainboard NFC chip;
s204: and repeatedly sending the current frame image data of the target resolution to the target screen device through the mainboard NFC chip.
After sending one frame of image data to the target screen device, if the target screen device receives the image data, the response information may be returned to the processing chip, so that the processing chip sends the next frame of image data. If the target screen device is damaged or water enters, the target screen device cannot return response information to the processing chip. At this time, the same image data can be repeatedly sent to the target screen device, and the sending times of the current frame image data with the target resolution can be repeatedly sent are recorded; and if the sending times are greater than the preset times, generating screen abnormity prompt information. The form of the screen abnormality prompt message includes, but is not limited to, voice, vibration, and LED (Light Emitting Diode) lamp flashing.
