[0004] AMOLED displays boast self-luminous technology, vibrant colors, fast response times, high contrast, low power consumption, wide viewing angles, high refresh rates, and a thin and lightweight design. Consequently, they are favored by numerous smartphone manufacturers and are increasingly being adopted in high-end, mid-range, and low-end mobile phones, wearables, and other display-enabled products. Furthermore, when choosing a display, users often consider factors such as the breadth of the color gamut, refresh rate, dimming accuracy, and maximum and minimum brightness, all of which AMOLED offers superior performance.

[0005] Currently, for display driver ICs, activating the display and transitioning it to a working state (e.g., DISPLAY_ON) is paramount. Failure to activate the display is considered an incident, so quickly and accurately activating the display is crucial. Typically, switching the display state requires receiving corresponding command information, necessitating additional command transmission, reception, and analysis modules. This can lead to delayed signal transmission and reception and complicated circuit design.

[0046] Before introducing the embodiments of the present application, a brief introduction to the technical concepts involved in the present application is first given.

[0047] MIPI (Mobile Industry Processor Interface) protocol: A processor interface standard for mobile devices. It defines the communication interface within a mobile device (e.g., between the application processor and peripherals such as the display, camera, and touchscreen). MIPI interfaces can help reduce pin count, power consumption, and cost in mobile devices while providing high-bandwidth and low-latency data transmission.

[0048] DISPLAY_ON state: An operating state of an AMOLED display, indicating that the display is active and can display content normally. When the AMOLED display driver IC receives the video signal sent by the host computer and successfully transitions to the DISPLAY_ON state, the display begins to present images and video content. It is important to note that in order to ensure the display maintains stable and high-performance operation over a long period of time, parameters such as screen brightness, contrast, and color in the DISPLAY_ON state typically require precise control and adjustment. Furthermore, when not displaying content, the display may enter a low-power mode or standby state to conserve energy and extend its lifespan.

[0049] The inventors of the present application have noticed that AMOLED display screens have the advantages of self-luminous technology, bright colors, fast response speed, high contrast, low power consumption, wide viewing angle, high refresh rate, and thinness. Therefore, AMOLED display screens are favored by many smartphone manufacturers and are gradually used in high-end, mid-end, and low-end mobile phones and wearable products with display functions. At the same time, users will also compare the breadth of the color gamut, the refresh rate, the fineness of the dimming, the maximum and minimum brightness, and other intuitive feelings when making choices, and AMOLED is more competent for all of them. At present, in the display field, driving ICs and activating the display screen to jump to the working state (such as DISPLAY_ON state) are the top priorities. Failure to activate the display screen is considered an accident, so it is particularly important to be able to activate the display screen more quickly and correctly. In the absence of COMMAND, changing the IC state to the display screen display state can switch more quickly and save instructions.

[0050] In view of this, the embodiments of the present application provide a display screen display method, device, equipment and storage medium as described below. The display method can be applied to application scenarios where display screens such as LED display screens and liquid crystal display screens are driven by ICs for display.

[0051] Please refer to FIG1 , which is a flow chart of a display screen display method provided by an embodiment of the present application. The embodiment of the present application is explained in detail below. The method includes: step 100 and step 120.

[0052] Step 100: Receive a video signal;

[0053] Step 120: Based on the video signal, drive the display screen to jump to the working state for display.

[0054] For example, a video signal can be a digital or analog signal used to drive a display screen. After proper processing and conversion, it is correctly displayed by the display screen, typically involving steps such as signal decoding, format conversion, color correction, and scaling. For example, a common video signal is a VIDEO signal. The operating state can be: the display screen is activated and can normally display content, such as the DISPLAY_ON state of an AMOLED display screen. When the AMOLED display screen driver IC receives the video signal sent by the host computer and successfully switches to the DISPLAY_ON state, the display screen will begin to present images and video content. This state ensures that the brightness and color performance of the display screen are at their optimal state, providing users with a high-quality visual experience. In the DISPLAY_ON state, the pixels of the AMOLED display screen are activated and emit light to form the desired image. Due to the self-luminous nature of AMOLED technology, each pixel can independently control brightness and color, resulting in a more vivid and realistic picture effect.

[0055] Alternatively, the video signal is described using a VIDEO signal as an example, and the operating state is described using the DISPLAY_ON state of an AMOLED display as an example. After the host computer sends the VIDEO signal, the display receives it and directly switches to the DISPLAY_ON state. Normally, the display sends a DISPLAY_ON command and then switches to the DISPLAY_ON state. This step is omitted because the decoding circuit in the driver IC detects the VIDEO signal from the host computer, causing the state machine to directly switch to the DISPLAY_ON state and subsequently display the content normally.

[0056] By receiving a valid video signal, the driver IC will automatically jump to the working state immediately without waiting for additional driving instructions. This automatic jump mechanism greatly reduces the delay in instruction transmission and processing, saving resources, time, and instructions, and has a fast response speed.

[0057] In one embodiment, step 100 may include: step 101 .

[0058] Step 101: Detect the VIDEO signal sent by the host computer through the MIPI decoding circuit to determine the video signal.

[0059] For example, the MIPI decoding circuit can be a key component in implementing MIPI protocol functions. It is responsible for decoding the data signals on the MIPI interface so that the various components within the device can correctly understand and process the data. The MIPI decoding circuit is typically integrated into the mobile device's motherboard or dedicated interface chip, working in conjunction with the processor and other peripherals to achieve efficient and reliable data transmission. As shown in Figure 2, the MIPI decoding circuit is located in the integrated circuit of the driver IC chip. When the host computer sends VIDEO, it is detected by the MIPI decoding circuit in the driver IC. At this time, when the host computer detects that it has sent VIDEO, it no longer needs to issue the DISPLAY_ON command. It can directly jump to the DISPLAY_ON state and then execute the instructions and operations after DISPLAY_ON.

[0060] In one embodiment, step 101 may include: step 1011 , step 1012 and step 1013 .

[0061] Step 1011: Receive the data packet sent by the host computer through the MIPI decoding circuit;

[0062] Step 1012: Detect the header field of the data packet;

[0063] Step 1013: If the packet header field contains the data type of the VIDEO signal, it is determined that the host computer has sent the video signal.

[0064] For example, both the host computer as the sender and the MIPI decoding circuit of the IC driver chip as the receiver need to comply with the provisions of the MIPI protocol. When MIPI sends a data packet, the packet header contains datatype information, i.e., a packet type identifier. The packet header usually contains a field that identifies the packet type, which helps the receiving end identify the type of the packet and thus know how to parse and process the rest of the packet. Datatype is used to define the format and structure of the data transmitted on the interface. It covers the data encoding method, transmission rate, data type, and other related parameters. These data types can include images, video (VIDEO), audio, control signals, etc. In the image transmission of the embodiment of the present application, MIPI datatype is used to transmit video data. This data is transmitted to the processor or display of the mobile device via the D-PHY interface. In VIDEO mode, video data can only be transmitted via HS mode (high-speed mode). According to the MIPI protocol, different datatypes correspond to different sending packet headers. After decoding, the MIPI decoding circuit of the IC driver chip receives the packet header information and determines the data type in the packet header information to determine whether it is a VIDEO signal. Different packet headers correspond to different data types.

[0065] In one embodiment, step 120 may include: step 121 , step 122 and step 123 .

[0066] Step 121: parsing the data packet of the video signal based on the MIPI protocol of the video data;

[0067] Step 122: converting the format of the video data in the data packet to obtain a video frame suitable for the display screen;

[0068] Step 123: Jump to the working state and display the video frame.

[0069] For example, the MIPI decoding circuit in the driver IC detects the video signal, identifies the start and end of the data packet, and parses the content of the data packet according to the MIPI protocol specification. By identifying the synchronization signals in the data packet (such as frame synchronization and line synchronization signals), the correct alignment of the data is ensured. According to the provisions of the MIPI protocol, the video data, control information, error detection information, etc. in the data packet are decoded. If the decoded image data is not in a directly displayable format (such as RGB), format conversion is required. For example, from YUV format to RGB format. Depending on the requirements of the AMOLED display, the image may need to be scaled or cropped. Color correction algorithms can be further applied to improve image quality, such as contrast enhancement, sharpening, etc. The adapted image data is sent to the AMOLED display for display.

[0070] In one embodiment, before step 100 , the following steps may be included: step 80 and step 90 .

[0071] Step 80: If it is determined that no video signal is received, then determine whether the instruction sent by the host computer includes a display drive instruction;

[0072] Step 90: If it is determined that the instruction sent by the host computer includes a display driving instruction, the display screen is driven to jump to the working state for display based on the display driving instruction.

[0073] For example, as shown in Figure 3, the MIPI decoding circuit detects whether the host computer sends a VIDEO signal. If so, the system automatically jumps to the DISPLAY_ON state. If the MIPI decoding circuit does not detect that the host computer sends a VIDEO signal, the system continues to execute the next instruction, which the host computer sends according to the instruction sequence and also sends the DISPLAY_ON instruction. After the host computer sends the DISPLAY_ON instruction, the system changes to the DISPLAY_ON state. Otherwise, the system does not send the DISPLAY_ON instruction and remains in the DISPLAY_OFF state. Even if the DISPLAY_ON instruction is detected, the system will not switch to the DISPLAY_ON state until the VIDEO signal is sent.

[0074] In one embodiment, the video signal is received during a time period after the display screen is disturbed by electrostatic discharge and enters a black screen state.

[0075] For example, the driver IC's internal MIPI decoding circuit detects whether the host computer has sent a video to determine whether it needs to enter the DISPLAY_ON state directly. After detecting that the host computer has sent a video, it can directly enter the DISPLAY_ON state. Even if it is disturbed by adverse factors such as ESD (electrostatic discharge) and mistakenly enters the AMOLED display's DISPLAY_OFF (black screen state) mode, or the DISPLAY_ON command is invalid, it can still automatically switch back to the DISPLAY_ON state by detecting that the host computer has sent a video, ensuring normal display and stronger ESD resistance.

[0076] In one embodiment, the display driving instruction includes: an instruction set in an LCD display screen or an OLED display screen driver IC; and the working state includes: a display screen activation state.

[0077] For example, the instruction set in the driver IC for LCD and OLED displays may vary depending on the specific chip and manufacturer, but may include initialization instructions for setting the initial state of the display, such as setting the operating voltage, pixel format, and scanning direction; display control instructions for controlling the display state of the display, such as turning the display on and off, setting brightness and contrast, etc.; data write instructions for writing image data or command parameters to the display; and read instructions for reading state or data from the display or driver IC. For example, the instruction set may include the DISPLAY_ON instruction for controlling the display state of the LCD and OLED displays, and the operating state may be the DISPLAY_ON state of the LCD and OLED displays.
