[0042] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0044] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.
[0045] Figure 1 FIG. 1 is a schematic diagram showing a display control device according to an embodiment of the present disclosure. Figure 1 As shown, the device includes: a display driving module 11 and a touch control module 12,
[0046] The display driving module 11 includes a parameter register unit 112 and a state register unit 113.
[0047] The parameter registering unit 112 is used to register parameter data, and the parameter data is used to define the working mode of the display component; the state registering unit 113 is used to register state data, and the state data is used to indicate the type of the working mode of the display component;
[0048] The touch control module 12 includes a storage unit 122 and a first control unit 121. The first control unit 121 is connected to the storage unit 122, the parameter register unit 112 and the state register unit 113 respectively.
[0049] The storage unit 122 is used to store parameter data corresponding to multiple working modes of the display component;
[0050] Wherein, the first control unit 121 is used for:
[0051] Reading the status data in the status register unit 113;
[0052] When the status data is updated, determining a target operating mode to be switched to by the display component according to the updated status data;
[0053] The parameter data corresponding to the target working mode is read from the storage unit 122 , and the read parameter data is written into the parameter register unit 112 , so that the display component performs display in the target working mode.
[0054] In a possible implementation, the display control device 10 can be used to control the working mode of a display component. For example, the display control device 10 can be applied to a touch display device (such as a smart phone, a tablet computer, etc.) to control the working mode of a display component (such as a display screen) of the touch display device and drive the display component to work in a corresponding working mode.
[0055] In a possible implementation, the display component may include multiple types of working modes, such as working modes with standard, warm or cool color temperatures; working modes with standard, vivid or eye protection colors, etc. The multiple types of working modes of the display component may correspond to different working parameters, and parameter data corresponding to the multiple working modes of the display component may be pre-stored so as to be loaded as needed during operation.
[0056] It should be understood that the working mode of the display component can be set according to actual conditions, and the present disclosure does not limit this.
[0057] In one possible implementation, the display control device 10 may include a display driver module 11 and a touch module 12. The display driver module 11 is used to determine the working mode of the display component and drive the display component to work in the corresponding working mode; the touch module 12 is used to store parameter data corresponding to the working mode of the display component and load the parameter data into the display driver module 11.
[0058] In a possible implementation, the touch control module 12 can also implement touch control of the display component, and perform corresponding processing according to the user's touch action on the display component. The present disclosure does not limit the functional scope of the touch control module 12.
[0059] In a possible implementation, the display driver module 11 may include a parameter storage unit 112 and a state storage unit 113. The parameter storage unit 112 may include, for example, a register group for storing parameter data corresponding to the working mode of the display component. By reading the parameter data stored in the parameter storage unit 112, the working parameters required for adjusting the working mode of the display component can be obtained; the state storage unit 113 may include, for example, one or more registers for storing state data, the state data being used to indicate the type of the working mode of the display component. By reading the state data stored in the state storage unit 113, the working mode of the display component can be determined.
[0060] For example, when the working mode of the display component is standard color temperature, that is, the category of the working mode of the display component is standard color temperature, the parameter data stored in the reference storage unit 112 may be the working parameters for adjusting the working mode of the display component to the standard color temperature; the status data stored in the status storage unit 113 may be the status data for determining that the working mode of the display component is the standard color temperature.
[0061] In a possible implementation, the touch control module 12 may include a storage unit 122 and a first control unit 121. The storage unit 122 may be, for example, an erasable memory such as a flash memory, for storing parameter data corresponding to multiple working modes of the display component and various data related to touch control. The present disclosure does not specifically limit the specific device type of the storage unit 122.
[0062] In a possible implementation, the first control unit 121 may be, for example, a microcontroller unit (MCU), a field programmable gate array FPGA, etc., for touch control of the display component. The first control unit 121 may be connected to the storage unit 122, the parameter register unit 112, and the state register unit 113 through an SPI interface, an I2C interface, etc. The present disclosure does not limit the device type of the first control unit 121 and the connection method with each component.
[0063] In a possible implementation, the initial working mode of the display component may be the default working mode of the device, or other working modes set by the user. During operation, the working mode of the display component may need to be switched. In this case, the parameter data corresponding to the working mode to be switched may be loaded into the parameter storage unit 112 through the first control unit 121.
[0064] In one possible implementation, the first control unit 121 can read the status data in the status storage unit 113 at a preset time interval; if the status data has not been updated, it can be considered that there is no need to switch the working mode of the display component; if the status data has been updated, it can be considered that the working mode of the display component needs to be switched. In this case, the target working mode of the display component to be switched can be determined based on the updated status data.
[0065] In one possible implementation, the first control unit 121 may read parameter data corresponding to the target operating mode from the storage unit, and write the read parameter data into the parameter storage unit 112, so that the display driving module 11 drives the display component according to the parameter data, so that the display component displays in the target operating mode.
[0066] According to the display control device of the embodiment of the present disclosure, the working parameters can be stored in the storage unit of the touch control module; during the operation of the device, the state of the working mode in the state register unit is read by the first control unit; when the state is updated, the working mode corresponding to the updated state is determined; the corresponding working parameters are read from the storage unit and written into the parameter register unit, thereby realizing the switching of the working mode of the display component. In this way, the storage space of the one-time programmable storage structure OTP in the display driver module can be effectively saved.
[0067] like Figure 1 As shown, in a possible implementation, the storage unit 122 includes an erasable and writable memory.
[0068] In a possible implementation, the storage unit 122 may be, for example, an erasable memory such as a flash memory, and the present disclosure does not specifically limit the specific device type of the storage unit 122 .
[0069] In a possible implementation, the storage unit 122 is used to store parameter data corresponding to multiple working modes of the display component and various data related to touch control. In this way, the storage space of the one-time programmable storage structure OTP in the display driver module can be effectively saved, and the flexibility of modifying the working parameters can be improved.
[0070] Figure 2 FIG. 1 is a schematic diagram showing a display control device according to an embodiment of the present disclosure. Figure 2 As shown, in a possible implementation, the display driving module 11 further includes a second control unit 114, and the second control unit 114 is connected to the parameter register unit 112, the state register unit 113 and the first control unit 121.
[0071] The second control unit 114 is used to: when the working mode of the display component is to be switched, update the state data in the state register unit 113 to the state data corresponding to the target working mode, and send an interrupt signal to the first control unit 121;
[0072] The first control unit 121 reads the status data in the status register unit 113 , including: reading the status data in the status register unit 113 when receiving the interrupt signal.
[0073] In a possible implementation, the second control unit 114 may be, for example, a digital signal processor (DSP), a field programmable gate array FPGA, etc., for reading parameter data in the parameter register unit 112 and controlling the display component to display in a corresponding working mode. Among them, the second control unit 121 may be connected to the parameter register unit 112, the state register unit 113 and the first control unit 121 respectively through an SPI interface, an I2C interface, etc. The present disclosure does not limit the device type of the second control unit 114 and the connection method with each component.
[0074] In a possible implementation, when the working mode of the display component is to be switched, the second control unit 114 may update the state data in the state register unit 113 to the state data corresponding to the target working mode to be switched, and send an interrupt signal to the first control unit 121. When receiving the interrupt signal, if the touch module 12 is not working or the first control unit 121 is in a dormant state, the first control unit 121 may be awakened by the interrupt signal and respond to the interrupt signal; if the first control unit 121 is in a working state, it may directly respond to the interrupt signal.
[0075] In one possible implementation, in response to the interrupt signal, the first control unit 121 may read status data from the status register unit 113; if the read status data has been updated, the target operating mode to be switched is determined based on the updated status data; and parameter data corresponding to the target operating mode is read from the storage unit 122, and the read parameter data is written into the parameter register unit 112, so that the display driver module 11 drives the display component according to the parameter data, so that the display component displays in the target operating mode.
[0076] In a possible implementation, the second control unit 114 may also control the display component to display in the target working mode by reading the parameter data in the parameter storage unit 112 .
[0077] In this way, when the working mode of the display component is to be switched, the second control unit updates the status data and sends an interrupt signal to the first control unit; the first control unit reads the updated status data according to the interrupt signal, reads the corresponding working parameters from the storage unit and writes them into the parameter register unit, thereby switching the working mode of the display component. In this way, the number of times the first control unit reads the status data can be effectively reduced, and the working efficiency of the first control unit can be improved.
[0078] like Figure 2 As shown, in a possible implementation, the display driver module 11 is also connected to an external interface 13, and the external interface 13 is used to transmit a signal of an external control component (not shown).
[0079] The display driver module 11 further includes an interface monitoring unit 111 for monitoring whether there is signal transmission on the external interface 13; when there is signal transmission, the interface status flag 14 is set to be valid;
[0080] The parameter data corresponding to the target working mode includes multiple groups of parameter data, and the first control unit transmits one group of parameter data each time.
[0081] The first control unit 121 is further configured to:
[0082] When there is parameter data to be transmitted, detecting the interface status flag 14;
[0083] When the detected interface status flag 14 is invalid, a set of parameter data to be transmitted is read from the storage unit 122, and the read set of parameter data is transmitted to the parameter register unit 112;
[0084] When the transmission of the set of parameter data is completed, the interface status flag 14 is detected again;
[0085] When the interface status flag 14 detected again is invalid, it is determined that the set of parameter data is written successfully.
[0086] For example, the display driver module 11 can be connected to the external interface 13 through an SPI interface, an I2C interface, etc., to receive a signal transmitted by an external control component. The external interface 13 may include, for example, a mobile industry processor interface (MIPI), or other interfaces, as long as the signal of the external control component can be transmitted. The present disclosure does not limit the specific type of the external interface 13.
[0087] In a possible implementation, the external control component can access the display driver module 11 through the external interface 13, and transmit signals to the display driver module 11, such as writing parameter data to the parameter register unit 112. When the first control unit 121 writes parameter data to the parameter register unit 112, an access conflict may occur with the external interface 13, resulting in data writing errors.
[0088] In a possible implementation, the display driver module 11 may also be provided with an interface monitoring unit 111 for monitoring whether there is signal transmission on the external interface 13. The interface monitoring unit 111 may include, for example, an edge detection circuit, and the present disclosure does not limit the specific implementation of the interface monitoring unit 111.
[0089] In a possible implementation, if there is signal transmission, the interface monitoring unit 111 is triggered, and the state of the interface state flag 14 is set to be valid, indicating that the external interface 13 is accessing the display driver module 11, and the first control unit 121 is prohibited from writing parameter data to the parameter storage unit 112. On the contrary, if there is no signal transmission, the interface monitoring unit 111 is not triggered, and the state of the interface state flag 14 is not updated.
[0090] In a possible implementation, before the first control unit 121 writes parameter data to the parameter register unit, the state of the interface state flag 14 may be detected first. If the state of the interface state flag 14 is valid, the parameter data is not written temporarily, the state of the interface state flag 14 is set to invalid, and the test is performed again after a certain period of time. The parameter data is written to the parameter register unit 112 until the state of the interface state flag 14 is detected to be invalid and no access conflict occurs.
[0091] In a possible implementation, the amount of parameter data for each working mode may be large, and the writing process of the first control unit 121 may be divided into multiple times, that is, a portion of the parameter data is written each time. In this case, it is assumed that the parameter data corresponding to the target working mode includes multiple groups of parameter data, and the first control unit 121 transmits one group of parameter data each time. Before each transmission of parameter data, it is necessary to detect the state of the interface status flag 14.
[0092] In one possible implementation, when there is at least one set of parameter data to be transmitted, the first control unit 121 may detect an interface status flag; if the detected interface status flag 14 is invalid, a set of parameter data to be transmitted is read from the storage unit 122, and the read set of parameter data is transmitted to the parameter storage unit 112.
[0093] In one possible implementation, when the transmission of the group of parameter data is completed, the first control unit 121 may detect the interface status flag 14 again; if the interface status flag 14 detected again is invalid, it is determined that the group of parameter data is written successfully; conversely, if the interface status flag 14 detected again is valid, it means that an access conflict occurs and the writing of the group of parameter data fails.
[0094] In this way, data writing errors caused by access conflicts can be avoided, thereby improving the reliability of parameter data written into the parameter register unit 112.
[0095] In a possible implementation manner, the first control unit 121 is further configured to:
[0096] When the interface status flag 14 detected again is valid, it is determined that the writing of the set of parameter data fails, and the interface status flag 14 is set to invalid.
[0097] That is to say, when the transmission of a set of parameter data is completed, the first control unit 121 detects the interface status flag 14 again; if the interface status flag 14 detected again is valid, it means that an access conflict has occurred, and the writing of this set of parameter data has failed. The status of the interface status flag 14 is set to invalid, and it waits for a certain period of time before detecting again so as to rewrite the set of parameter data.
[0098] In this way, the reliability of the parameter data written into the parameter register unit 112 can be improved.
[0099] In a possible implementation manner, the first control unit 121 is further configured to:
[0100] When the set of parameter data is written successfully, the next set of parameter data to be transmitted is read from the storage unit 122 , and the read next set of parameter data is transmitted to the parameter register unit 112 .
[0101] That is to say, if a set of parameter data is written successfully, that is, the interface status flag 14 has been detected to be invalid, the first control unit 121 can directly read the next set of parameter data to be transmitted from the storage unit 122, and transmit the read next set of parameter data to the parameter storage unit 112; when the transmission of the next set of parameter data is completed, the interface status flag 14 can be detected again to determine whether the writing is successful.
[0102] In this way, the first control unit 121 can implement cyclic writing of multiple sets of parameter data until the transmission of all parameter data is completed.
[0103] Figure 3FIG. 1 is a schematic diagram showing a first control unit of a display control device according to an embodiment of the present disclosure transmitting data to a parameter storage unit. Figure 3 As shown, when there is parameter data to be transmitted, the interface status flag 14 is detected; when the detected interface status flag 14 is valid, the interface status flag 14 is returned to be re-detected; when the detected interface status flag 14 is invalid, a set of parameter data to be transmitted is read from the storage unit 122 through the first control unit 121, and the read set of parameter data is transmitted to the parameter storage unit 112.
[0104] like Figure 3 As shown, when the transmission of the group of parameter data is completed, the interface status flag 14 is detected again; if the interface status flag 14 is detected again as invalid, it means that no access conflict occurs during the writing process, and it is determined that the writing of the group of parameter data is successful; conversely, if the interface status flag 14 is detected again as valid, it means that an access conflict occurs during the writing process, and it is determined that the writing of the group of parameter data fails, and the interface status flag 14 is set to invalid.
[0105] like Figure 3 As shown, after setting the interface status flag 14 to invalid, the group of parameter data is retransmitted to the status register unit 113; when the transmission of the group of parameter data is completed, the interface status flag 14 is detected again. After the last group of parameter data is written successfully, the entire parameter data writing process can be completed.
[0106] According to the display control device of the embodiment of the present disclosure, parameter data corresponding to the working mode of the display component is stored in the erasable storage unit of the touch module, and the parameter data is loaded into the display driver module through the control unit of the touch module, which can effectively save the storage space of the one-time programmable storage structure OTP in the display driver module and improve the flexibility of modifying the working parameters.
[0107] According to the display control device of the embodiment of the present disclosure, an interface monitoring unit is provided for monitoring external interface access, which can set the interface status to valid when there is access; the control unit can detect the interface status when loading parameter data, thereby avoiding data writing errors caused by access conflicts and improving the reliability of parameter data written to the display driver module.
