The meaning of "plurality" is two or more unless specifically limited otherwise.
In order to explain the technical solutions of the present application, the following detailed descriptions are made with reference to specific drawings and examples.
The digital video standard (DP) interface is a digital video interface standard developed by the PC and chip manufacturers alliance, the Video Electronics Standards Association (VESA) standard. The interface is free of authentication and authorization fund, is mainly used for connecting a video source and display equipment and also supports carrying audio, USB and other forms of data. The digital video standard was the first display communication port to rely on packetized data transfer technologies found in ethernet, USB, and PCI Express technologies. It can be used for both internal and external display connections. Unlike past standards that require fixed transmission of timer signals within differential pairs at each output, the digital video standard protocol is based on small data packets called micro-packets that can embed timer signals in the data stream. Its advantage is less pins and higher resolution. The use of data messaging also allows for scalability using the digital video standard, which means that over time additional functionality can be added without significant changes to the physical communication port itself. Digital video standards are available for simultaneous transmission of audio and video, each of which can be transmitted separately without the other. Each color channel in the video signal path may have 6 to 16 bits, the audio path may have up to 8 channels of 24-bit 192kHz uncompressed PCM audio, or the compressed audio format may be encapsulated in an audio stream. A bi-directional, half-duplex auxiliary channel carries device management and device control data for the main link, such as the VESADID, MCCS, and DPMS standards. Further, the communication port is capable of carrying bidirectional USB signals.
The digital video standard signal is not compatible with DVI or HDMI. However, dual-mode digital video standard s, which is designed to transmit the protocol of single-link DVI or HDMI1.2/1.4 over the communication port, needs to be implemented using an external passive connector, select the desired signal, and convert the electrical signal from LVDS to TMDS. Dual-mode digital video standard s with passive connectors does not support VGA and dual-link DVI. These communication ports require active connectors to convert the protocols and signals that are required to be output. VGA connectors may be powered using digital video standard connectors, while dual-link DVI connectors may rely on external power. The digital video standard connector can have 1, 2 or 4 differential data pairs (lanes) in a main link, and each lane can have an original code rate of 1.62, 2.7 or 5.4Gbit/s on the basis that the self-timer runs at 162, 270 or 540 MHz. The data is 8b/10b encoded, i.e. every 8-bit message is encoded in 10-bit symbols. Therefore, the effective data transmission rate per channel after decoding is 1.296, 2.16, 4.32Gbit/s.
Fig. 1 is a schematic flowchart of an upgrade method provided in an embodiment of the present application, where the upgrade method is used to upgrade firmware of a display device carrying a digital video standard interface, and referring to fig. 1, the upgrade method includes:

Therefore, the signal of the digital video standard interface can be correctly transmitted only by ensuring that the signal of the AUX is correct, and liquid crystal modules of different digital video standard protocols have different requirements on the amplitude of the AUX output signal. For example, when the liquid crystal module detection equipment detects the liquid crystal module, various liquid crystal module test devices with matched AUX output amplitudes need to be designed for the liquid crystal modules with different digital video standard protocols, so that the test cost of the liquid crystal module is obviously increased.
