Therefore, the features defined as "first", "second", "third", etc. may explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0020] At present, during the development phase of display devices (such as TVs, computer monitors, projectors, electronic whiteboards, virtual reality head-mounted displays, etc.), the whole machine factory basically performs Tconless screen configuration manually. Tconless screen configuration refers to the process of integrating the functions of TCON (Timing Controller) into the system-on-chip (System on Chip, SOC) and directly driving the screen end for display through the SOC. Due to the differences in the configuration parameters of different screen ends, when the existing whole machine factory performs Tconless screen configuration on the display device, Tconless screen configuration is required for each screen end and when the same screen end is equipped with different SOCs, resulting in a large workload for the whole machine factory to configure the screen.

[0021] Therefore, in order to solve the above problems, the present application proposes an automatic screen configuration method and a display device. The present application is further described below in conjunction with the accompanying drawings and implementation methods.

[0022] See also Figure 1 , Figure 1 A first flow chart of the automatic screen configuration method provided in an embodiment of the present application. This embodiment provides an automatic screen configuration method, which is applied to a display device, the display device includes a screen end and a system-level chip, the screen end stores first screen configuration information, and the automatic screen configuration method includes: S110. The system-level chip obtains first screen configuration information from the screen end.

[0023] In some embodiments, the display device includes a screen and a system on a chip (SOC), and the function of the timing controller (TCON) of the display device is integrated on the SOC, that is, the display device in this embodiment is a display device without a timing controller (TCON) (i.e., a Tconless display device). In this embodiment, by integrating the function of the timing controller (TCON) on the SOC, the structure of the display device can be simplified and the cost of the display device can be reduced.

[0024] In some embodiments, the screen end includes a circuit board, and the circuit board can be a horizontal circuit board (x-board, XB board) or a control board (Circuit Board, CB board). The circuit board is connected to the system-level chip through a hardware interface, and a first memory is provided on the circuit board, and the first memory is used to store the first screen configuration information.

[0025] Furthermore, the step of the system-level chip obtaining the first screen configuration information from the screen end specifically includes: the system-level chip obtains the first screen configuration information from the first memory of the screen end through a preset communication protocol. For example, the system-level chip obtains the first screen configuration information from the first memory of the screen end through the SPI protocol.

[0026] In some embodiments, the first memory may be one or more of a memory chip Flash IC, a random access memory (Random Access Memory, RAM), a read-only memory (Read-Only Memory, ROM), etc., which is not limited in this embodiment.

[0027] In some embodiments, the circuit board includes a plurality of sub-boards, the hardware interface includes a plurality of interfaces corresponding to the plurality of sub-boards, each sub-board is connected to the SOC through its corresponding interface, and the first memory is disposed on any sub-board. Figure 3 As shown, the circuit board adopts a two-stage horizontal circuit board (x-board, XB board), that is, the circuit board includes two sub-boards, the hardware interface includes a dual 60-pin hardware interface corresponding to the two sub-boards, and the first memory is set on one of the sub-boards. Of course, the circuit board in the embodiment of the present application can also include three sub-boards, four sub-boards or more sub-boards, which is not limited in this embodiment.

[0028] In some embodiments, the hardware interface is a standardized interface. By standardizing the hardware interface, the automatic screen configuration method provided in the embodiments of the present application can be applied to different display devices.

[0029] S120. The system-level chip drives the screen end to display based on the first screen configuration information to achieve automatic screen configuration of the display device.

[0030] In some embodiments, the first screen configuration information includes a first screen configuration parameter in a first format and a second screen configuration parameter in a second format, and the system-level chip includes a screen configuration driver module, and the screen configuration driver module is used to drive the screen end for display.

[0031] Furthermore, the step of the system-level chip driving the screen end for display based on the first screen configuration information specifically includes: the system-level chip performs format conversion on the first screen configuration parameters in the first format and the second screen configuration parameters in the second format to obtain third screen configuration parameters in the third format; the system-level chip initializes the screen configuration driver module based on the third screen configuration parameters to drive the screen end for display through the initialized screen configuration driver module.

[0032] Since the underlying communication data formats of each SOC are different, this embodiment converts the first screen configuration parameter in the first format and the second screen configuration parameter in the second format to the format of internal communication of the SOC. For example, the 8-bit first screen configuration parameter and the 8-bit second screen configuration parameter are converted into the 10-bit third screen configuration parameter.

[0033] In some embodiments, the first screen configuration parameter includes at least one of voltage, current, GOA timing parameter and register setting parameter. In this embodiment, by storing the first screen configuration parameter in a first memory in a unified format, different SOCs can obtain the first screen configuration parameter from the first memory, so that the automatic screen configuration method provided by the present application can be applied to different display devices. For example, the voltage, current, GOA timing parameter and register setting parameter can be converted into a DCCD.Bin document through the DCCD protocol, and then the DCCD.Bin document can be saved to the first memory.

[0034] In some embodiments, the second screen configuration parameter is a perceptual quantization (PQ) parameter of the display device, and the second screen configuration parameter includes at least one of an adaptive contrast control (ACC) parameter, a demura parameter, a gamma parameter, and an OverDrive (QD) parameter. In addition, since the second screen configuration parameters of display devices of different manufacturers are different, in order to realize automatic screen configuration of different display devices, the second screen configuration parameter can be saved in the first memory according to a preset file format and a predefined storage location, so that when the screen is automatically configured, the SOC can obtain the second screen configuration parameter from the first memory according to the predefined address.

[0035] In some embodiments, see Figure 2 , Figure 2 A second flow chart of the automatic screen configuration method provided in an embodiment of the present application, the automatic screen configuration method comprising: S210: Store the third screen configuration parameters in a second memory.

[0036] In this embodiment, the system-level chip includes a second memory. After the system-level chip performs format conversion on the first screen configuration parameters in the first format and the second screen configuration parameters in the second format to obtain third screen configuration parameters in the third format, the system-level chip can store the third screen configuration parameters in the second memory, so that after the display device is powered on again, the third screen configuration parameters stored in the second memory can be used for automatic screen configuration.

[0037] S220: When the display device is turned on again, the first version information is obtained from the screen end.

[0038] In some embodiments, the screen configuration information stored in the screen end includes version information. For example, as shown in Table 1, the screen configuration information mainly includes a basic data segment, a product information data segment, a screen configuration information data segment, a special field, a check Sum, etc., wherein the basic data segment includes version information. In this embodiment, the first version information is the version information in the configuration information obtained from the screen end when the display device is turned on again.

[0039] Table 1 Screen configuration information framework table

[0040] Table 1

[0041] S230. Determine whether the first version information matches the second version information corresponding to the third screen configuration parameter.

[0042] In this embodiment, the second version information is the version information corresponding to the screen configuration information obtained during the last automatic screen configuration. Generally speaking, when the screen configuration information of the screen end has not changed, the second version information corresponding to the screen configuration information obtained during the last screen configuration matches the first version information obtained during the current screen configuration; when the screen configuration information of the screen end changes, the second version information corresponding to the screen configuration information obtained during the last screen configuration does not match the first version information obtained during the current screen configuration. Therefore, based on the first version information and the second version information, it can be determined whether the screen configuration information of the screen end has changed.

[0043] S240. If the first version information and the second version information match, obtain the third screen configuration parameter from the second memory, and initialize the screen configuration driver module based on the third screen configuration parameter, so as to drive the screen end to display through the initialized screen configuration driver module.

[0044] In this embodiment, if the first version information and the second version information match, indicating that the screen configuration information of the screen has not changed, the third screen configuration parameters can be directly obtained from the second memory, and the screen configuration driver module can be initialized based on the third screen configuration parameters, so as to drive the screen end for display through the initialized screen configuration driver module. In this case, since there is no need to repeatedly obtain the screen configuration information from the screen end each time the screen is configured, the efficiency of automatic screen configuration can be improved.

[0045] S250: If the first version information and the second version information do not match, obtain second screen configuration information from the screen end, and drive the screen end to display based on the second screen configuration information.

[0046] In this embodiment, if the first version information and the second version information do not match, indicating that the screen configuration information of the screen has changed, then when automatic screen configuration is performed again, it is necessary to re-acquire the second screen configuration information from the screen, and drive the screen to display based on the second screen configuration information. In this way, when the screen or the system-level chip is replaced, the screen configuration information can be re-acquired from the screen through the system-level chip for automatic screen configuration, thereby realizing the arbitrary replacement of the screen and the system-level chip, and enabling the replaced screen and system-level chip to be plug-and-play.

[0047] Furthermore, the step of obtaining the second screen configuration information from the screen is the same as the aforementioned step S110, and the step of driving the screen to display based on the second screen configuration information is the same as the aforementioned step S120. For details, please refer to the aforementioned steps S110 and S120. To avoid repetition, this embodiment will not be repeated here.

[0048] In some embodiments, the system-level chip includes a second memory. After the system-level chip drives the screen end to display based on the first screen configuration information, it includes: storing the first screen configuration information in the second memory; when the display device is turned on again, obtaining the second version information from the screen end; judging whether the second version information matches the second version information in the first screen configuration information; if the first version information and the second version information match, obtaining the first screen configuration information from the second memory, and driving the screen end to display based on the first screen configuration information; if the first version information and the second version information do not match, obtaining the second screen configuration information from the screen end, and driving the screen end to display based on the second screen configuration information.

[0049] The difference between this embodiment and the above steps S210 to S250 is that this embodiment directly stores the first screen configuration information in the second memory, while the above steps S210 to S250 store the third screen configuration parameters obtained after converting the first screen configuration information in the second memory. In this embodiment, when the first version information and the second version information match, since there is no need to repeatedly obtain the first screen configuration information from the screen end, the efficiency of automatic screen configuration can also be improved. In addition, when the screen end or the system-level chip is replaced, the screen configuration information can be obtained from the screen end again through the system-level chip for automatic screen configuration, which can realize the arbitrary replacement of the screen end and the system-level chip, and can make the replaced screen end and system-level chip plug-and-play.

[0050] In order to better implement the automatic screen matching method in the embodiment of the present application, on the basis of the automatic screen matching method, a display device is also provided in the embodiment of the present application. The display device can be any device with display function such as a TV, a computer monitor, a projector, an electronic whiteboard, a virtual reality head-mounted display, etc. Figure 3As shown, the display device includes: a screen end 10 and a system-level chip 20. Among them, the screen end 10 stores the first screen configuration information; the system-level chip 20 is used to obtain the first screen configuration information from the screen end 10, and drive the screen end 10 to display based on the first screen configuration information, so as to realize the automatic screen configuration of the display device. The display device provided in this embodiment can obtain the first screen configuration information from the screen end 10 through the system-level chip 20 and drive the screen end 10 to display based on the first screen configuration information, so as to realize the automatic screen configuration of the display device. In addition, when the display device replaces the screen end 10 or the system-level chip 20, the system-level chip 20 can re-acquire the configuration information from the screen end for automatic screen configuration, so as to realize the plug-and-play of the screen end 10 and the system-level chip 20.

[0051] In some embodiments, the function of the timing controller (TCON) of the display device is integrated on the SOC, that is, the display device is a display device without a timing controller (TCON) (i.e., a TCONless display device). In this embodiment, by integrating the function of the timing controller (TCON) on the SOC, the structure of the display device can be simplified and the cost of the display device can be reduced.

[0052] In some embodiments, continue to refer to Figure 3 As shown, the screen end 10 of the display device also includes: a circuit board 11 and a first memory 12. Among them, the circuit board 11 is connected to the system-level chip 20 through a hardware interface 13; the first memory 12 is set on the circuit board 11, and the first memory 12 is used to store the first screen configuration information. Such a setting enables the system-level chip 20 to obtain the first screen configuration information from the first memory 12 of the screen end 10 through a preset communication protocol, thereby realizing automatic screen configuration of the display device. For example, the system-level chip 20 obtains the first screen configuration information from the first memory 12 of the screen end through the SPI protocol.

[0053] In some embodiments, the circuit board 11 may be a horizontal circuit board (x-board, XB board) or a control board (Circuit Board, CB board). The first memory 12 may be one or more of a memory chip Flash IC, a random access memory (Random Access Memory, RAM), and a read-only memory (Read-Only Memory, ROM), etc., which is not limited in this embodiment.

[0054] In some embodiments, the circuit board 11 includes multiple sub-boards, the hardware interface 13 includes multiple interfaces corresponding to the multiple sub-boards, each sub-board is connected to the system-level chip 20 through its corresponding interface, and the first memory 12 is set on any sub-board. Figure 3 As shown, the circuit board 11 adopts a two-stage horizontal circuit board (x-board, XB board), that is, the circuit board 11 includes two sub-boards, the hardware interface 13 includes a dual 60-pin hardware interface corresponding to the two sub-boards, and the first memory 12 is set on one of the sub-boards. Of course, the circuit board 11 in the embodiment of the present application can also include three sub-boards, four sub-boards or more sub-boards, which is not limited in this embodiment.

[0055] In some embodiments, the hardware interface 13 is a standardized interface. By standardizing the hardware interface 13, the automatic screen configuration method provided in the embodiment of the present application can be applied to different display devices.

[0056] In some embodiments, the first screen configuration information includes a first screen configuration parameter in a first format and a second screen configuration parameter in a second format, and the system-level chip 20 includes: a screen configuration driver module. The screen configuration driver module is used to drive the screen end 10 to display; the system-level chip 20 is specifically used to: convert the first screen configuration parameter in the first format and the second screen configuration parameter in the second format to obtain a third screen configuration parameter in a third format, and initialize the screen configuration driver module based on the third screen configuration parameter, so as to drive the screen end 10 to display through the initialized screen configuration driver module.

[0057] Since the underlying communication data formats of each system-level chip 20 are different, in this embodiment, the first screen configuration parameter in the first format and the second screen configuration parameter in the second format are converted by the system-level chip 20, so that the first screen configuration parameter and the second screen configuration parameter can be converted into the format of internal communication of the system-level chip 20. For example, the 8-bit first screen configuration parameter and the 8-bit second screen configuration parameter are converted into the 10-bit third screen configuration parameter.

[0058] In some embodiments, the first screen configuration parameter includes at least one of voltage, current, GOA timing parameter and register setting parameter. In this embodiment, by storing the first screen configuration parameter in a unified format in the first memory 12, different system-level chips 20 can obtain the first screen configuration parameter from the first memory 12, so that the automatic screen configuration method provided by the present application can be applied to different display devices. For example, the voltage, current, GOA timing parameter and register setting parameter can be converted into a DCCD.Bin document through the DCCD protocol, and then the DCCD.Bin document is saved to the first memory 12.

[0059] In some embodiments, the second screen configuration parameter is a perceptual quantization (PQ) parameter of the display device, and the second screen configuration parameter includes at least one of an adaptive contrast control (ACC) parameter, a demura parameter, a gamma parameter, and an OverDrive (QD) parameter. In addition, since the second screen configuration parameters of display devices of different manufacturers are different, in order to realize automatic screen configuration of different display devices, the second screen configuration parameter can be saved in the first memory 12 according to a preset file format and a predefined storage location, so that when the screen is automatically configured, the SOC can obtain the second screen configuration parameter from the first memory 12 according to the predefined address.

[0060] In some embodiments, the system-level chip 20 includes: a second memory, and the system-level chip 20 is specifically used to: store the third screen configuration parameters in the second memory; when the display device is turned on again, obtain the first version information from the screen end 10; determine whether the first version information and the second version information corresponding to the third screen configuration parameters match; if the first version information and the second version information match, obtain the third screen configuration parameters from the second memory, and initialize the screen configuration driver module based on the third screen configuration parameters, so as to drive the screen end 10 for display through the initialized screen configuration driver module; if the first version information and the second version information do not match, obtain the second screen configuration information from the screen end 10, and drive the screen end for display based on the second screen configuration information.

[0061] In the display device provided by the embodiment of the present application, when the first version information and the second version information match, that is, the screen configuration information of the screen end 10 has not changed, the system-level chip 20 can directly obtain the third screen configuration parameter from the second memory for automatic screen configuration, without repeatedly obtaining the screen configuration information from the screen end 10, which can improve the efficiency of automatic screen configuration. When the first version information and the second version information do not match, that is, the screen configuration information of the screen end 10 changes, the system-level chip 20 can re-acquire the screen configuration information from the screen end 10 for automatic screen configuration, thereby realizing the arbitrary replacement of the screen end 10 and the system-level chip 20, and enabling the replaced screen end 10 and the system-level chip 20 to achieve plug-and-play.
