Description

Technical Field

[0001] This application relates to the field of image display technology, specifically to an image display method and display device. Background Technology

[0002] In the field of image display, there are scenarios where a front-end master device simultaneously drives three back-end slave devices. For example, due to the immaturity of single-chip full-color display using micro-sized light-emitting diodes (LEDs), current front-end application processors (APs) for augmented reality (AR) displays based on micro-sized LEDs need to split the red, green, and blue (RGB) data of the image into three channels (R, G, and B) and simultaneously drive them to the back-end display driver to achieve three-chip combined full-color display. This requires the front-end AP to perform complex separation processing, which in turn increases the size and cost of the display device.

[0003] Therefore, how to reduce the size and cost of display devices is a technical problem that urgently needs to be solved. Summary of the Invention

[0004] This application provides an image display method and a display device. In the display device, the application processor directly sends the image to be displayed to each display chip in the display chip module. The display chip extracts the target color channel data in the image to be displayed according to the extraction circuit and displays it. The front-end AP does not need to perform complex separation processing on the image to be displayed, which can reduce the size and manufacturing cost of the display device.

[0005] In a first aspect, an image display method is provided, applied to a display device. The display device includes an application processor and a display chip module connected to the application processor. The display chip module includes N display chips, each display chip including a receiving interface and an extraction circuit. The receiving interfaces of the N display chips are respectively connected to the sending interface of the application processor, where N is an integer greater than or equal to 2. The method includes: the application processor sending an image to be displayed to each of the N display chips, the image to be displayed including M color channel data, where M is an integer greater than or equal to 2; the display chip receiving the image to be displayed and extracting P target color channel data from the image to be displayed according to the extraction circuit for display, where 1 ≤ P < M.

[0006] This application provides an image display method in which the application processor in the display device directly sends the image to be displayed to each display chip in the display chip module. The display chip extracts the target color channel data in the image to be displayed according to the extraction circuit and displays it. The front-end AP does not need to perform complex separation processing on the image to be displayed, which can reduce the size and manufacturing cost of the display device.

[0007] It should be understood that the application processor can connect to the display chip module via a one-to-n data cable.

[0008] For example, the image to be displayed can be an RGB image, a CMYK image, or a Lab image. When the image to be displayed is an RGB image, M=3, and the RGB image includes three color channel data: red (R), green (G), and blue (B). When the image to be displayed is a CMYK image, M=4, and the CMYK image includes four color channel data: cyan (C), magenta (M), yellow (Y), and black (K). When the image to be displayed is a Lab image, M=3, and the Lab image includes three color channel data: lightness, red-green hue (a-axis), and yellow-blue hue (b-axis).

[0009] This application does not limit the format of the image to be displayed. For example, when the image to be displayed is an RGB image, the RGB image can be in the format of RGB888, RGB666, RGB101010, RGB121212, RGB565, RGB555, RGB444, RGB332, etc.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, each of the N receiving interfaces of the N display chips includes a terminating resistor, and the terminating resistors of the N receiving interfaces are connected in parallel.

[0011] The display chip's receiving interface may include a receive (RX) channel, and terminating resistors may be included in the display chip's RX channel. It should be understood that since the N display chips in the display chip module are respectively connected to the application processor's transmitting interface, the terminating resistors of the N receiving interfaces of the display chips are connected in parallel.

[0012] This application provides an image display method in which the application processor in the display device is connected to N display chips respectively, and directly sends the image to be displayed to each display chip in the display chip module. The display chip extracts the target color channel data in the image to be displayed according to the extraction circuit and displays it. The front-end AP does not need to perform complex separation processing on the image to be displayed, which can reduce the size and manufacturing cost of the display device.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, at least some of the N receiving interfaces share a terminating resistor.

[0014] It should be understood that the terminating resistors of a display chip module are typically used to match the output impedance of the front-end AP transmitting interface to ensure maximum signal power transmission and minimum reflection. Since the terminating resistors of the N display chip receiving interfaces are connected in parallel in this application, the resistance value of the terminating resistors in the display chip module will decrease. Therefore, this application can configure at least some of the N receiving interfaces to share a terminating resistor, for example, by completely turning off the terminating resistors of some receiving interfaces, to increase the resistance value of the terminating resistors in the display chip module.

[0015] This application provides an image display method in which at least some of the receiving interfaces of N display chips share a terminating resistor, thereby increasing the resistance value of the terminating resistor in the display chip module, ensuring that the input impedance of the display chip and the output impedance of the AP are matched, and improving the quality of the transmitted signal.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the terminating resistance of the receiving interface is Q times the terminating resistance of the transmitting interface, where 1 < Q ≤ N+1.

[0017] It should be understood that the terminating resistors of the display chip module are typically used to match the output impedance of the front-end AP's transmitting interface to ensure maximum signal power transmission and minimum reflection. Since the terminating resistors of the N display chip receiving interfaces are connected in parallel in this application, the resistance value of the terminating resistors in the display chip module will decrease. Therefore, to improve the quality of the transmitted signal, the resistance value of the terminating resistors in the receiving interfaces of the display chips can be increased. For example, the resistance values ​​of the terminating resistors in the N display chips can be increased by a factor of Q, making the resistance value of the terminating resistor of each display chip receiving interface Q times the resistance value of the terminating resistor of the front-end application processor's transmitting interface. In one possible implementation, N=3, the resistance values ​​of the terminating resistors in the three display chips can be increased by a factor of 3, making the resistance value of the terminating resistor of each display chip receiving interface 3 times the resistance value of the terminating resistor of the front-end application processor's transmitting interface, ensuring that the input impedance of the display chips and the output impedance of the AP are matched, thus improving the quality of the transmitted signal.

[0018] This application provides an image display method in which the terminating resistor of the display chip's receiving interface is Q times the terminating resistor of the application processor's transmitting interface, where 1 < Q ≤ N+1. This increases the terminating resistor value in the display chip module, ensuring impedance matching between the display chip's input and the application processor's output impedance, thereby improving the quality of the transmitted signal.

[0019] In conjunction with the first aspect, in some implementations of the first aspect, the display chip further includes a display unit, wherein the display chip receives the image to be displayed and extracts P target color channel data from the image to be displayed according to the extraction circuit for display, including: the receiving interface receiving the image to be displayed and sending the image to be displayed to the extraction circuit; the extraction circuit extracting the P target color channel data from the image to be displayed; and the display unit displaying the P target color channel data.

[0020] For example, the image to be displayed is an RGB888 format image. The receiving interface of the display chip receives the image to be displayed sent by the application processor and sends the image to the extraction circuit. Each pixel of the RGB888 format image corresponds to 3 bytes, i.e., 24 bits 0-23. In this embodiment, bits 0-7 of the 24 bits of each pixel represent R channel data, bits 8-15 represent G channel data, and bits 16-23 represent B channel data. The display chip can extract the required target color channel data according to the configuration information in the extraction circuit, such as any one or more of R channel data, G channel data, and B channel data, and then control the display unit to display the target color channel data.

[0021] This application provides an image display method in which the application processor in the display device directly sends the image to be displayed to each display chip in the display chip module. The display chip extracts the target color channel data in the image to be displayed according to the extraction circuit and displays it. The front-end AP does not need to perform complex separation processing on the image to be displayed, which can reduce the size and manufacturing cost of the display device.

[0022] In conjunction with the first aspect, in some implementations of the first aspect, the transmitting interface and the receiving interface are high-speed serial interfaces (HSSI).

[0023] A high-speed serial interface is a serial interface standard that uses high-speed transmission technology and protocols to achieve high-speed, reliable, and stable data transmission.

[0024] For example, the transmitting interface and the receiving interface may be a mobile industry processor interface (MIPI) or a low voltage differential signaling (LVDS) interface, etc. This application does not limit the specific type of the transmitting interface and the receiving interface.

[0025] In conjunction with the first aspect, in some implementations of the first aspect, the image to be displayed includes an RGB image, and the M color channel data includes R channel data, G channel data, and B channel data.

[0026] Secondly, a display device is provided, comprising an application processor and a display chip module connected to the application processor. The display chip module comprises N display chips, each display chip comprising a receiving interface and an extraction circuit. The receiving interfaces of the N display chips are respectively connected to the transmitting interface of the application processor, where N is an integer greater than or equal to 2. The application processor is configured to send an image to be displayed to each of the N display chips. The image to be displayed comprises M color channel data, where M is an integer greater than or equal to 2. The display chips are configured to extract P target color channel data from the image to be displayed according to the extraction circuit for display, where 1 ≤ P < M.

[0027] In conjunction with the second aspect, in some implementations of the second aspect, each of the N receiving interfaces of the N display chips includes a terminating resistor, and the terminating resistors of the N receiving interfaces are connected in parallel.

[0028] In conjunction with the second aspect, in some implementations of the second aspect, at least some of the N receiving interfaces share a terminating resistor.

[0029] In conjunction with the second aspect, in some implementations of the second aspect, the terminating resistance of the receiving interface is Q times the terminating resistance of the transmitting interface, where 1 < Q ≤ N+1.

[0030] In conjunction with the second aspect, in some implementations of the second aspect, the receiving interface is used to receive the image to be displayed and send the image to be displayed to the extraction circuit.

[0031] In conjunction with the second aspect, in some implementations of the second aspect, the display chip further includes a display unit for displaying the P target color channel data.

[0032] In conjunction with the second aspect, in some implementations of the second aspect, the transmitting interface and the receiving interface are high-speed serial interfaces.

[0033] In conjunction with the second aspect, in some implementations of the second aspect, the image to be displayed includes an RGB image, and the M color channel data includes red (R) channel data, green (G) channel data, and blue (B) channel data.

[0034] The beneficial effects of the second aspect and any possible implementation of the second aspect correspond to the beneficial effects of the first aspect and any possible implementation of the first aspect, which will not be elaborated further.

[0035] Thirdly, an electronic device is provided, including a transmission component and a display device as described in the second aspect and any possible implementation thereof, wherein the transmission component is used to transmit image data to be displayed to the display device.

As those skilled in the art will know, with the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0050] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0052] To facilitate understanding of the embodiments of this application, some definitions involved in this application will be briefly explained first.

[0053] 1. Augmented Reality (AR): A technology that uses precise calculations of the position and angle of camera images, combined with image analysis techniques, to allow the virtual world on the screen to be combined with and interact with real-world scenes.

[0054] 2. Full-color combined: A display method that controls RGB semiconductor light-emitting diodes. A full-color LED display screen is composed of many RGB three-color light-emitting diodes. Each pixel combination has RGB diodes, and different colors of full-color images are displayed by turning each group of pixel lights on and off.

[0055] 3. Impedance matching: When the internal resistance of the signal source is equal in magnitude and phase with the characteristic impedance of the connected transmission line, or when the characteristic impedance of the transmission line is equal in magnitude and phase with the impedance of the connected load, the input or output of the transmission line is said to be in an impedance-matched state, or simply impedance matching. Otherwise, it is called impedance mismatch.

[0056] Figure 1 This is a schematic diagram of a working scenario where a master device drives three slave devices, as provided in an embodiment of this application.

[0057] In the field of image display, there are scenarios where a front-end master device simultaneously drives three back-end slave devices. For example, due to the immaturity of single-chip full-color micro-LEDs, current front-end application processors (APs) for augmented reality (AR) displays based on micro-LEDs need to decompose the red-green-blue (RGB) image into three channels: red (R), green (G), and blue (B), and simultaneously drive them to the back-end display driver to achieve three-chip combined full-color display. This requires the front-end AP to perform complex separation processing, which in turn increases the size and cost of the display device.

[0058] Figure 2 This is a schematic diagram of how RGB image data is split using an adapter in existing technology.

[0059] like Figure 2As shown, the front-end AP sends RGB data to the adapter via the transport (TX) channel of the Mobile Industry Processor Interface (MIPI). The adapter receives the RGB data via the receive (RX) channel of the MIPI and splits it into R, G, and B channels, then forwards it to the subsequent display chip via the Low Voltage Differential Signaling (LVDS) interface. The subsequent display chip receives the R, G, and B channel data via LVDS and performs color combining for display.

[0060] Figure 2 The existing technology shown requires an adapter to split and forward data from the R, G, and B channels. The display device needs to reserve space for the adapter, and there are many board-level traces, resulting in a large size of the board-level interconnect channels. For example, if the RGB image data sent by the AP is in RGB888 format, and each bit of the RGB data requires a corresponding trace, then a total of 24 traces are required at the board level.

[0061] Figure 3 This is a structural example diagram of a display device provided in an embodiment of this application.

[0062] Display device 300 includes an application processor 310 and a display chip module 320 connected to the application processor 310. The display chip module 320 includes N display chips, where N is an integer greater than or equal to 2. Each display chip includes a receiving interface and an extraction circuit. The receiving interfaces of the N display chips are respectively connected to the transmitting interface of the application processor. It should be understood that the application processor 310 can be connected to the display chip module 320 via a one-to-N data cable.

[0063] Application processor 310 is used to send an image to be displayed to each of the N display chips. The image to be displayed includes M color channel data, where M is an integer greater than or equal to 2.

[0064] Display chips 1 to N are used to extract P target color channel data from the image to be displayed according to the extraction circuit, where 1 ≤ P < M.

[0065] Figure 4 This is an exemplary flowchart of an image display method provided in an embodiment of this application. This image display method is applied to... Figure 3 The display device 300 shown.

[0066] 410, The application processor sends the image to be displayed to each display chip.

[0067] The application processor 310 sends an image to be displayed to each of the N display chips in the display chip module 320. The image to be displayed includes M color channel data, where M is an integer greater than or equal to 2.

[0068] For example, the image to be displayed can be an RGB image, a CMYK image, or a Lab image. When the image to be displayed is an RGB image, M=3, and the RGB image includes three color channel data: red (R), green (G), and blue (B). When the image to be displayed is a CMYK image, M=4, and the CMYK image includes four color channel data: cyan (C), magenta (M), yellow (Y), and black (K). When the image to be displayed is a Lab image, M=3, and the Lab image includes three color channel data: lightness, red-green hue (a-axis), and yellow-blue hue (b-axis).

[0069] This application does not limit the format of the image to be displayed. For example, when the image to be displayed is an RGB image, the RGB image can be in the format of RGB888, RGB666, RGB101010, RGB121212, RGB565, RGB555, RGB444, RGB332, etc.

[0070] 420, the display chip extracts the target color channel data for display.

[0071] The display chip receives the image to be displayed and extracts P target color channel data from the image according to the extraction circuit for display, where 1 ≤ P < M.

[0072] Figure 5 This is an exemplary flowchart of an image display method provided in an embodiment of this application. Figure 6 This is an example diagram of extracting RGB image color channel data provided in an embodiment of this application. Figure 6 and Figure 5 correspond.

[0073] 510, the front-end AP sends RGB data to the back-end display chip.

[0074] like Figure 6 As shown, the AP acquires the RGB data of the image to be displayed, and sends the RGB data to the display chip module 600 via a one-to-three data cable using MIPI. The display chip module 600 includes three downstream display chips 610, 620 and 630.

[0075] 520, the subsequent display chip extracts data from the R, G and / or B channels for display.

[0076] The RGB data of the image to be displayed includes the RGB data of each pixel in the image. Based on the RGB data of each pixel in the image to be displayed, the subsequent display chip can extract any one or more of the R channel data, G channel data, and B channel data corresponding to each pixel.

[0077] Figure 7 This is a schematic diagram illustrating the extraction of RGB888 format image channel data according to an embodiment of this application. For example... Figure 7 As shown, each pixel in an RGB888 format image corresponds to 3 bytes, or 24 bits 0-23. In this embodiment, bits 0-7 of the 24 bits for each pixel represent R channel data, bits 8-15 represent G channel data, and bits 16-23 represent B channel data. The subsequent display chip can extract the required target color channel data, such as any one or more of R channel data, G channel data, and B channel data, based on the configuration information in the extraction circuit. It should be understood that... Figure 7 In this application, bits 0-7 represent R channel data, bits 8-15 represent G channel data, and bits 16-23 represent B channel data. This is for illustrative purposes only. The 3 bytes of color channel data for each pixel can be set according to requirements. For example, bits 0-7 can represent B channel data, bits 8-15 can represent G channel data, and bits 16-23 can represent R channel data. The specific color channel data represented by different bits should not be construed as a limitation of this application.

[0078] Figure 8 This is a schematic diagram illustrating the extraction of RGB666 format image channel data according to an embodiment of this application. For example... Figure 8 As shown, each pixel in an RGB666 format image corresponds to 18 bits (0-17). In this embodiment, bits 0-5 of the 18 bits represent the R channel data, bits 6-11 represent the G channel data, and bits 12-17 represent the B channel data. The subsequent display chip can extract the required target color channel data, such as any one or more of the R channel data, G channel data, and B channel data, based on the configuration information in the extraction circuit. It should be understood that... Figure 8 In this application, bits 0-5 represent R channel data, bits 6-11 represent G channel data, and bits 12-17 represent B channel data. This is for illustrative purposes only. Bits 0-5 can also be used to represent G channel data, bits 6-11 to represent B channel data, and bits 12-17 to represent R channel data. The specific color channel data represented by different bits should not be construed as a limitation of this application.

[0079] Similarly, images in formats such as RGB101010, RGB121212, RGB565, RGB555, RGB444, and RGB332 can also be formatted using... Figure 7 and Figure 8 The method shown extracts different color channel data. This application does not restrict the format of the image to be displayed.

[0080] Optionally, a single display chip can be used to extract data from multiple color channels. For example, display chip module 600 includes display chip 610 and display chip 620, which can be configured to extract R and G channel data, and display chip 620 to extract B channel data. The display chip module can include multiple display chips. Figure 6 The number of display chips included in the display chip module 600 shown should not be construed as a limitation of this application.

[0081] 530, improves the quality of transmitted signals.

[0082] Figure 9 This is a structural example diagram of a display chip 610 provided in an embodiment of this application. Display chips 620 and 630 have the same structure as display chip 610. Display chip 610 includes a set of clock signal lines and a set of data signal lines, each set of clock signal lines and data signal lines including two lines, meaning display chip 610 includes four traces. PAD1~PAD4 on display chip 610 are pin interfaces around the chip, used to connect to external circuits and transmit clock signals or data signals. Exemplarily, PAD1 and PAD2 can be connected to two data signal lines to transmit data signals, and PAD3 and PAD4 can be connected to two clock signal lines to transmit clock signals.

[0083] Each of the display chips 610, 620, and 630 includes a receive interface, such as MIPI, and each receive interface includes an RX channel, which includes at least one terminating resistor R1. It should be understood that the terminating resistor of the display chip's receive interface is typically used to match the output impedance of the preceding AP's transmit interface to ensure maximum signal power transmission and minimal reflection. The selection of the terminating resistor can affect the performance and stability of the display chip; an incorrect resistor selection may lead to signal distortion, reflection, and interference, thereby affecting display quality and system performance.

[0084] like Figure 6As shown, because the terminating resistors of the three display chips 610-630 are connected in parallel in this embodiment, the resistance value of the terminating resistor in the display chip module 600 will decrease. Therefore, in order to improve the quality of the transmitted signal, the resistance value of the terminating resistor in the display chip receiving interface can be increased. For example, the resistance value of the terminating resistor of the MIPI RX channel in the display chips 610-630 can be increased by a factor of Q, that is, the resistance value of the terminating resistor of the RX channel of each display chip is Q times the resistance value of the terminating resistor of the TX channel of the front-end application processor transmitting interface, 1≤Q≤N+1, where N is the number of display chips included in the display chip module, and N is an integer greater than or equal to 2. In one possible implementation, because the three display chips 610-630 are connected in parallel in this embodiment, the resistance value of the terminating resistor in the receiving interface of the display chips 610-630 can be increased by a factor of 3, that is, the resistance value of the terminating resistor of the RX channel of the receiving interface of each display chip is 3 times the resistance value of the terminating resistor of the TX channel of the front-end application processor transmitting interface, ensuring that the input impedance of the display chip and the output impedance of the AP are matched, thereby improving the quality of the transmitted signal.

[0085] Optionally, the terminating resistors of some of the display chips in display chips 610-630 can be disconnected, i.e., the selected terminating resistors can be left floating, thereby increasing the resistance value of the terminating resistors in the display chip module. For example, the terminating resistors of the RX channels of display chips 610 and 620 can be left floating and turned off, meaning that the three display chips 610-630 share the terminating resistor of display chip 630, thereby increasing the resistance value of the terminating resistors in the display chip module, ensuring that the input impedance of the display chip matches the output impedance of the AP, and improving the quality of the transmitted signal.

[0086] For RGB images, the image display method provided in this application embodiment does not require an additional adapter to split the RGB data; it can directly send the data to the subsequent display chip via a one-to-three driver. Simultaneously, only 12 traces are needed at the three display chip board level, reducing the size of the interconnect channels in the display device.

[0087] It should be understood that the data transmission via MIPI in the embodiments of this application is merely an example, and high-speed serial interfaces such as LVDS can also be used. This illustration should not be construed as a limitation of this application.

[0088] In some possible application scenarios, embodiments of this application can also extract CMYK image color channel data. A CMYK image includes four color channels: cyan (C), magenta (M), yellow (Y), and black (K). Figure 10 This is an example diagram illustrating the extraction of CMYK image color channel data provided in an embodiment of this application. For example... Figure 10As shown, the AP acquires CMYK data and sends the CMYK data to the display chip module 1000 via a one-to-four data line using MIPI. The display chip module 1000 includes four downstream display chips: 1010, 1020, 1030, and 1040.

[0089] In the CMYK 8-bit format, each pixel of a CMYK image is represented using 32 bits (i.e., 4 bytes), with each color channel represented using 8 bits (i.e., 1 byte). The subsequent display chip can extract the required color channel data based on specific bit positions, such as any one or more of the C channel, M channel, Y channel, and K channel data. The process of extracting color channel data from a CMYK image in this embodiment is similar to the process of extracting color channels from an RGB image; for details, please refer to [link to relevant documentation]. Figure 5-9 The description of the above will not be repeated here.
