Technical Field

[0001] This application relates to the field of display screen technology, and more specifically, to a display screen display method, apparatus, device, and storage medium. Background Technology

[0002] AMOLED displays boast self-emissive technology, vibrant colors, fast response times, high contrast, low power consumption, wide viewing angles, high refresh rates, and a slim profile. As a result, AMOLED displays are favored by numerous smartphone manufacturers and are increasingly being used in high-end, mid-range, and low-end phones, as well as wearable devices and other products with display capabilities. Meanwhile, users also consider factors like color gamut, refresh rate, dimming finesse, and maximum and minimum brightness—all intuitive aspects that AMOLED displays excel in.

[0003] Currently, in the display driver IC field, activating the display screen to switch to a working state (e.g., DISPLAY_ON state) is of paramount importance. Failure to activate the display screen is considered a malfunction, so faster and more accurate screen activation is crucial. Typically, display screen state switching requires receiving corresponding command information, necessitating additional command transmission and parsing modules, which can easily lead to untimely signal transmission and reception and redundant circuit design. Summary of the Invention

[0004] In view of the above, the purpose of this application is to provide a display screen method, apparatus, device and storage medium. By sending a video signal through a host computer, the display screen driver IC can quickly detect the signal change. Once a valid video signal is confirmed to be received, the driver IC will immediately and automatically switch to the working state without waiting for additional driving instructions. This automatic switching mechanism greatly reduces the delay in instruction transmission and processing, making the response of the entire display system faster, thereby solving the above-mentioned technical problems.

[0005] In a first aspect, embodiments of this application provide a display screen method, the method comprising: receiving a video signal; and driving the display screen to switch to a working state for display based on the video signal.

[0006] In the above implementation process, upon receiving a valid video signal, the driver IC will immediately and automatically switch to the working state without waiting for additional drive instructions. This automatic switching mechanism greatly reduces the delay in instruction transmission and processing, saves resources, saves time and instructions, and has a fast response speed.

[0007] Optionally, receiving the video signal includes:

[0008] The video signal is determined by detecting the VIDEO signal sent by the host computer through the MIPI decoding circuit.

[0009] In the above implementation process, the display screen is driven by receiving VIDEO signals, resulting in a fast response speed.

[0010] Optionally, the step of detecting the VIDEO signal sent by the host computer through the MIPI decoding circuit to determine the video signal includes:

[0011] Data packets sent by the host computer are received through the MIPI decoding circuit;

[0012] Inspect the header fields of the data packet;

[0013] If the header field contains the data type of a VIDEO signal, then it is determined that the host computer has sent the video signal.

[0014] In the above implementation process, the sent video signal is determined by parsing the header field of the MIPI data packet, which improves the response speed.

[0015] Optionally, driving the display screen to switch to the working state for display based on the video signal includes:

[0016] Based on the MIPI protocol for video data, the data packets of the video signal are parsed;

[0017] The video data in the data packet is converted to a different format to obtain video frames adapted to the display screen.

[0018] Jump to the working state and display the video frame.

[0019] In the above implementation process, the data in the MIPI data packet is parsed and converted into a format suitable for the display screen, thus avoiding display failures.

[0020] Optionally, before receiving the video signal, the method further includes:

[0021] If it is determined that no video signal has been received, then determine whether the instructions sent by the host computer include display driver instructions;

[0022] If it is determined that the instruction issued by the host computer includes the display driver instruction, then the display screen is driven to switch to the working state and display based on the display driver instruction.

[0023] In the above implementation process, the display can still be driven by instructions even when no video signal is received, which improves display efficiency.

[0024] Optionally, the video signal reception time includes: after the screen goes black due to electrostatic discharge interference.

[0025] In the above implementation process, even if it is interfered with by adverse factors such as ESD, it can still start displaying normally if it accidentally enters DISPLAY_OFF mode, thus improving the ESD resistance.

[0026] Optionally, the display driving instructions include: the instruction set in the LCD display or OLED display driver IC; the operating state includes: the display screen active state.

[0027] In the above implementation process, the display screen is started and displayed normally by driving the instruction set, which improves the response effect.

[0043] Before introducing the embodiments of this application, a brief introduction to the technical concepts involved in this application will be given first.

[0044] MIPI (Mobile Industry Processor Interface) protocol: A mobile device industry processor interface standard that defines a communication interface within a mobile device (such as between the application processor and peripherals like displays, cameras, and touchscreens). The MIPI interface helps reduce the number of pins, power consumption, and cost of mobile devices while providing high-bandwidth and low-latency data transmission.

[0045] DISPLAY_ON state: This is a working state of an AMOLED display, referring to the stage where the display is active and can display content normally. When the AMOLED display driver IC receives a video signal from the host computer and successfully transitions to the DISPLAY_ON state, the display will begin to present images and video content. It's important to note that to ensure the display maintains a stable and optimal working state over a long period, parameters such as screen brightness, contrast, and color in the DISPLAY_ON state typically require precise control and adjustment. Furthermore, when content is not needed, the display may enter a low-power mode or standby state to save energy and extend its lifespan.

[0046] The inventors of this application have noted that AMOLED displays possess advantages such as self-emissive technology, vibrant colors, fast response times, high contrast, low power consumption, wide viewing angles, high refresh rates, and thinness. Therefore, AMOLED displays are favored by many smartphone manufacturers and are gradually being used in high-end, mid-range, and low-end smartphones, as well as wearable devices and other products with display capabilities. Meanwhile, users also compare factors such as the breadth of color gamut, refresh rate, dimming finesse, and maximum and minimum brightness when making their choices, and AMOLED excels in all these aspects. Currently, in the display field, activating the display and transitioning it to a working state (e.g., DISPLAY_ON state) is paramount for display driver ICs. Failure to activate the display is considered a failure, so faster and more accurate display activation is crucial. Without a COMMAND, switching the IC state to the display state allows for faster transitions and saves commands.

[0047] In view of the above, embodiments of this application provide a display screen method, apparatus, device, and storage medium as described below. This display method is applicable to application scenarios where LED displays, LCD displays, and other displays utilize IC drivers for display.

[0048] Please see Figure 1 , Figure 1 This is a flowchart illustrating a display screen method provided in an embodiment of this application. The embodiments of this application are explained in detail below. The method includes steps 100 and 120.

[0049] Step 100: Receive video signal;

[0050] Step 120: Based on the video signal, drive the display screen to switch to the working state for display.

[0051] For example, the video signal can be a digital or analog signal used to drive the display screen. After appropriate processing and conversion, it is correctly displayed on the screen, typically involving steps such as signal decoding, format conversion, color correction, and scaling; for example, a common video signal: a VIDEO signal. The operating state can be: the display screen is in an active state and can display content normally, such as the DISPLAY_ON state of an AMOLED display. When the AMOLED display driver IC receives the video signal sent by the host computer and successfully jumps 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 best, 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. Because AMOLED technology has self-emissive characteristics, each pixel can independently control its brightness and color, thus presenting a more vivid and realistic picture effect.

[0052] Optionally, 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 a VIDEO signal, the display receives the signal and directly switches to the DISPLAY_ON state. Under normal circumstances, a DISPLAY_ON command is sent, and then the display switches to the DISPLAY_ON state. By omitting the command sending step, the decoding circuit in the driver IC can detect that the host computer has sent a VIDEO signal, and the state machine directly switches to the DISPLAY_ON state, subsequently displaying the content normally.

[0053] Upon receiving a valid video signal, the driver IC will immediately and automatically switch to the working state without waiting for additional drive commands. This automatic switching mechanism greatly reduces the latency of command transmission and processing, saves resources, time, and commands, and has a fast response speed.

[0054] In one embodiment, step 100 may include step 101.

[0055] Step 101: Detect the VIDEO signal sent by the host computer through the MIPI decoding circuit to determine the video signal.

[0056] For example, the MIPI decoding circuit can be a key part of implementing the MIPI protocol function. It is responsible for decoding the data signals on the MIPI interface so that the various components inside the device can correctly understand and process this data. The MIPI decoding circuit is typically integrated into the motherboard or dedicated interface chip of the mobile device, working in conjunction with the processor and other peripherals to achieve efficient and reliable data transmission. Figure 2 As shown, the MIPI decoding circuit is located in the integrated circuit of the driver IC chip. After the host computer sends VIDEO, it will be detected by the MIPI decoding circuit in the driver IC. At this time, after detecting that the host computer has sent VIDEO, there is no need to issue the DISPLAY_ON instruction again. It can directly jump to the DISPLAY_ON state and then execute the instructions and operations after DISPLAY_ON.

[0057] In one embodiment, step 101 may include steps 1011, 1012, and 1013.

[0058] Step 1011: Receive data packets sent by the host computer through the MIPI decoding circuit;

[0059] Step 1012: Detect the header fields of the data packet;

[0060] Step 1013: If the header field contains the data type of VIDEO signal, then it is determined that the host computer has sent a video signal.

[0061] 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 MIPI protocol. When MIPI sends data packets, the packet header contains datatype information, i.e., a data packet type identifier. The packet header typically includes a field identifying the data packet type, which helps the receiver identify the type of the data packet and thus know how to parse and process the rest of the data packet. The datatype is used to define the format and structure of the data transmitted on the interface, covering 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 this application embodiment, the MIPI datatype is used to transmit video data, which is transmitted to the processor or display screen of the mobile device through the D-PHY interface. In VIDEO mode, video data can only be transmitted through HS mode (high-speed mode). The MIPI protocol specifies that different datatypes correspond to different 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 sending a VIDEO signal. Different packet headers correspond to different data types.

[0062] In one embodiment, step 120 may include steps 121, 122 and 123.

[0063] Step 121: Based on the MIPI protocol of video data, parse the data packets of the video signal;

[0064] Step 122: Convert the video data in the data packet to obtain video frames adapted to the display screen;

[0065] Step 123: Jump to working status and display video frames.

[0066] 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. It ensures correct data alignment by identifying synchronization signals (such as frame synchronization and line synchronization signals) in the data packet. According to the MIPI protocol, it decodes the video data, control information, error detection information, etc., in the data packet. 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 and sharpening. The adapted image data is then sent to the AMOLED display for display.

[0067] In one embodiment, steps 80 and 90 may be included before step 100.

[0068] Step 80: If it is determined that no video signal has been received, then determine whether the instructions sent by the host computer include display driver instructions;

[0069] Step 90: If it is determined that the instruction issued by the host computer includes a display driver instruction, then drive the display screen to switch to the working state based on the display driver instruction to display.

[0070] For example, such as Figure 3As shown, the MIPI decoding circuit detects whether the host computer has sent a VIDEO signal. If a VIDEO signal is sent, the system automatically jumps to the DISPLAY_ON state. If the MIPI decoding circuit does not detect a VIDEO signal from the host computer, the system continues to execute the following instructions, which are sent in sequence by the host computer, along with the DISPLAY_ON instruction. Once the host computer sends the DISPLAY_ON instruction, the system enters 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 only switch to the DISPLAY_ON state after the VIDEO signal is sent.

[0071] In one embodiment, the video signal reception time includes: after the screen goes black due to electrostatic discharge interference.

[0072] For example, the driver IC's internal MIPI decoding circuit detects whether the host computer has sent a VIDEO signal to determine whether it needs to directly enter the DISPLAY_ON state. Once the host computer has sent a VIDEO signal, it can directly enter the DISPLAY_ON state. Even if it is interfered with by adverse factors such as ESD (electrostatic discharge) and accidentally enters the AMOLED display's DISPLAY_OFF (black screen state) mode, or if the DISPLAY_ON command is lost, it can still automatically switch back to the DISPLAY_ON state by detecting the host computer sending a VIDEO signal, ensuring normal display and stronger ESD resistance.

[0073] In one embodiment, the display driving instructions include: an instruction set in an LCD or OLED display driver IC; the operating state includes: a display activation state.

[0074] For example, the instruction sets in the driver ICs of LCD and OLED displays may vary depending on the specific chip and manufacturer, but they can all include initialization instructions for setting the initial state of the display, such as setting the operating voltage, pixel format, scanning direction, etc.; display control instructions for controlling the display state, such as turning the display on and off, setting brightness, contrast, etc.; data write instructions for writing image data or command parameters to the display; and read instructions for reading the state or data from the display or driver IC. For example, the instruction set may include a DISPLAY_ON instruction to control the display state of the LCD and OLED displays, and the operating state can be the DISPLAY_ON state of the LCD and OLED displays.
