All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an embodiment of the present application, there is provided a method embodiment of a field frequency adaptation method of a display device, it being noted that the steps shown in the flowchart of the figures may be performed in a computer system, such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order different from that herein.
For convenience of description, the following will describe some terms or terminology involved in the embodiments of the present application:
field frequency: when the LED display screen displays, the frequency of the video picture update is called field frequency, in Hz, for example: 50/60Hz.
Dclk/Gclk: in order to enable the driving chip of the LED display screen to work, the name of a clock signal sent to the driving chip is required, dclk represents a pixel clock signal, and Gclk represents a global clock signal;
clock frequency: refers to the frequency at which Dclk/Gclk operates; the change in frequency directly affects the length of the period of the LED display.
A lamp panel: the light emitting device is arranged on the bearing plate of the display screen. For example, LED light boards generally include a PCB (or aluminum substrate) and LED light beads soldered to the PCB (or aluminum substrate).
The LED display screen needs to be adaptive to different field frequencies for displaying, and the display effect of the display screen needs to be automatically adaptive after the field frequencies are changed, but the LED display screen is fast in updating iteration of a driving chip, numerous in manufacturers, free of unified protocols and the like, and software interfaces which are difficult to debug are required to be introduced for debugging each time of changing the field frequencies, and intermediate files are saved after the confirmation effect is finished through debugging. In the related art, if the optimized display of the LED display screen at the field frequencies of 50Hz/60Hz/… … is to be realized, the operation steps are as shown in FIG. 1, and the method comprises the following steps:
step S102, the display control device changes the field frequency;
step S104, the effect under the current field frequency is regulated at the software end;
step S106, determining a display effect;
step S108, a preset configuration file is stored at a software end;
step S110, issuing a combined configuration file through software.
Until all field effect debugging is completed. The effect confirmation requires manual input to complete judgment. And the end user packages the normal configuration parameters displayed under each field frequency into uniform configuration parameters, and uploads the uniform configuration parameters to the display control device through software. Therefore, each specific field frequency stores specific and fixed configuration parameters under the field frequency in hardware, and meanwhile, the display control device can judge the current working field frequency in real time and schedule the proper configuration parameters in real time. So as to realize the application of parameters under the current field frequency and optimize the display effect. The manpower debugging needs a great deal of investment, and the debugging time is increased along with the increase of the number of supported field frequencies. And the effect of manual debugging cannot be ensured, so that the related technology is difficult to widely apply. As the number of supported fields increases, the debugging time increases. The field frequency adapting device in the related art is shown in fig. 2, and includes: the system comprises a field frequency detection module, a configuration parameter scheduling module, a multi-configuration parameter storage space and a parameter execution unit.
Specifically, when the LED display screen needs to be normally turned on, the display control device is required to continuously send the data to the driving chip by the LED driving chip at a specific clock frequency, so that the display screen can work normally. The implementation method in the related art is to select a specific Dclk or a specific Gclk under a specific field frequency, so as to meet the parameter display under the current field frequency. As shown in fig. 3, the timing diagram of the driving chip indicates the current operating field frequency signal, and the Vsync pulse period is different from one field frequency to another. Dclk/Gclk represents clock signals which need to be output by a display control device when the device works normally; lat is used for storing data into a control signal of the LED display control chip; data is used for displaying Data output to the LED driving chip.
The method provided by the embodiment of the application can achieve the purpose of dynamically adapting the clock frequency by selecting the target clock frequency corresponding to the configuration parameter from a plurality of clock frequencies in the designated clock frequency range, thereby achieving the technical effect of setting the dynamic adaptation configuration parameter once, and further solving the technical problem of low field frequency adaptation efficiency caused by that each specific field frequency corresponds to the configuration parameter which is fixed in hardware storage. The following is a detailed description.
Fig. 4 is a field frequency adaptation method of a display device according to an embodiment of the present application, as shown in fig. 4, the method comprising the steps of:
step S402, obtaining configuration parameters of display equipment;
step S404, determining a target clock frequency corresponding to the configuration parameter from the designated clock frequency range;
step S406, outputting the target clock frequency to the display device to complete the field frequency adaptation of the display device.
It should be noted that, the configuration parameters of the display device may be directly obtained through the interactive interface, for example, may be input from the interactive interface, or may be obtained from the display device by the control device, where the configuration parameters include a driving chip parameter of the display device, a lamp panel parameter of the display device, and a field frequency of the display device.
In some embodiments of the present application, in step S404, there are various implementations of determining the target clock frequency corresponding to the configuration parameter from the specified clock frequency range, for example, a mapping table between the configuration parameter and the clock frequency may be maintained in the background, after the configuration parameter is determined, the target clock frequency corresponding to the configuration parameter is determined based on the mapping relationship between the configuration parameter and the clock frequency, or the specified frequency range may be used as a constraint first, by determining: receiving a reference clock of the display device; frequency division processing is carried out on the reference clock, so that a plurality of clock frequencies in the appointed clock range are obtained; a target clock frequency corresponding to the configuration parameter is selected from the plurality of clock frequencies. Specifically, a target clock of multiple clocks with different frequencies output by the field frequency control device is determined according to configuration parameters of the display device received through the interactive interface, and the target clock is divided into multiple clock frequencies to adapt to different field frequencies.
For example: when the display device works under the 60Hz field frequency, the time sequence is just adapted to 60Hz display, the adaptation indicates that the display effect is optimal under the time sequence, for example: the picture display is stable, for example, the field frequency (refresh rate) is higher than the corresponding threshold value, and the frequency of change of parameters such as brightness, chromaticity, contrast, color gamut and the like is smaller than the corresponding threshold value. However, when the field frequency is changed to 50Hz, the display time is long, the original 60Hz parameter is not applicable, and at this time, the Dclk and the Lat and Data signal periods corresponding to the Dclk and the Dclk need to be expanded, and all the operation periods are just adapted to 50Hz. When the field frequency is changed to an arbitrary field frequency, arbitrary variable Dclk and Gclk are required to be generated.
In the process of selecting the target clock frequency corresponding to the configuration parameter from the specified clock frequency range, the target clock frequency can be selected according to user experience, or the corresponding clock frequency can be determined according to different driving chips, and for the latter, the following steps can be realized: determining a clock frequency type corresponding to type information based on the type information of a driving chip in the display device; and determining a clock frequency corresponding to the clock frequency type from the designated clock frequency range, and taking the clock frequency corresponding to the clock frequency type as the target clock frequency.
It should be noted that the driving chip is a chip for controlling the lamp panel in the display device. It may include various types of chips such as a chip supporting only dclk (which may also be considered as a chip having only dclk) and a chip supporting both dclk and gclk (which may also be considered as a chip having both dclk and gclk), in which only dclk chip is provided with a PWM (Pulse Width Modulation ) control driving chip having a built-in phase locked loop; the chips supporting dclk and gclk are not provided with a built-in phase-locked loop; the type of the driving chip can be selected from the interactive interface, and the corresponding clock frequency type can be automatically adapted after the type of the driving chip is determined.
It should be noted that, when determining the chip type of the driving chip, the corresponding chip type may be read from the display device, or the corresponding chip type may be selected from the interactive interface displayed by the control device, that is: and responding to a selection instruction of the target object, and selecting from selectable types provided by the interactive interface.
In some embodiments of the present application, configuration parameters of a display device are obtained by: responding to an operation instruction aiming at a target control in the interactive interface; determining the lamp panel parameters of the lamp panel where the light-emitting element is located in the display device and the chip parameters of the driving chip in the display device, and taking the selected lamp panel parameters and the selected chip parameters as the configuration parameters of the display device, wherein fig. 5 shows a software interaction interface in the related art. It can be seen from fig. 5 that only a fixed clock frequency can be selected in the related art, for example, only a clock frequency having Dclk frequency of 8.93MHz can be selected.
It should be noted that, the target control may be a drop-down menu type option, and the configuration parameters in the drop-down menu may be selected by the operation instruction, or the configuration parameters may be input by the operation instruction.
In an alternative manner, a new input field may be added to the software interactive interface in the related art, after the driving chip model and the lamp panel model are selected, the device where the software interactive interface is located is triggered to obtain a recommended range of the corresponding designated clock frequency range from the pre-stored database, and then confirmation is performed by the user, for example, in response to the selection of the user, the responsive clock frequency is selected from the recommended range, so that the input efficiency is improved. Further, a drop-down menu may be added to the clock frequency input field, where a smaller clock frequency or frequency range may be provided, and the clock frequency range may be directly selected.
In some embodiments of the present application, the target clock frequency corresponding to the configuration parameter is selected from the specified clock frequency range, where the selection may be performed by a mapping relationship stored in a database in advance, or may be obtained by a calculation process, and for the latter, may be expressed in the following form: determining a field frequency period corresponding to the configuration parameter; obtaining lamp panel parameters of a lamp panel where a light-emitting element is positioned in the display equipment and chip parameters of a driving chip in the display equipment; determining the clock period of the driving chip according to the field frequency period, the lamp panel parameter and the chip parameter; and determining the target clock frequency according to the clock period.
It should be noted that, the lamp panel parameters and the chip parameters may be obtained from the interactive interface, for example, corresponding parameters may be selected from parameter options displayed on the interactive interface, where the lamp panel parameters include: the scanning number of the display screen, the resolution of the unit lamp panel on-load LED lamp points, and the chip parameters comprise: the number of driving chips and the number of driving chips on the lamp panel.
When determining the clock period of the driving chip according to the field frequency period, the lamp panel parameter and the chip parameter, the functional relationship among the field frequency period, the lamp panel parameter and the chip parameter can be used for determining the clock period of the driving chip, specifically, taking a driving chip as an example, the calculation formula of the target clock period is as follows:
wherein T is TargetGclkPeriod Representing a target clock period; t (T) RFU Representing the reserved time for ensuring that the core does not work abnormally in order to meet the time sequence requirement of the chip; t (T) DummyTime Representing the internal gradual change optimizing time set value of the driving chip; t (T) BlankPeriodPr The blanking time is used for indicating the time which is not displayed in the line feed period of the lamp panel; t (T) DeadTime Representing the internal blanking time set value of the driving chip; scrambleNum: the number of the driving chip intention times is larger, and the visual refresh rate is larger and is related to the visual refresh rate of the display screen; scanNum: representing the scanning number of the display screen; gclkNum: the parameters of the display screen are related to the gray level number and the visual refresh rate of the display screen, the larger the GclkNum is, the more the display content in one row is, and the larger the GclkNum is, the larger the gray level number is under the same intended number of times; vsPeriod represents the field period.
It should be further noted that, in the calculation process, vsPeriod is a field period, and belongs to a variable; other values are fixed after being selected, and the result value outputted by calculation can be correspondingly changed only after the Vperiod is changed. T (T) DummyTime
In some embodiments of the application, before selecting the target clock frequency corresponding to the configuration parameter from the specified clock frequency range, the method further comprises: judging whether the target clock frequency corresponding to the configuration parameter exists in the designated clock frequency range or not; and generating prompt information when the target clock frequency is not in the specified clock frequency range.
By judging whether the configuration parameters exist in the designated clock frequency range in advance and selecting the corresponding target clock frequency, invalid instructions are reduced, and response efficiency is improved.
Note that, the hint information is used to hint that the target clock frequency is not within the specified clock frequency range. The prompt may be displayed in the interactive interface. After the prompt message is triggered, the appointed clock frequency range can be input again; and in the case that the target clock frequency exists in the specified clock frequency range, selecting the target clock frequency in the specified clock frequency range by a field frequency control device to adapt with the field frequency.

step S604, receiving a designated clock frequency range through an interactive interface;
step S606, calculating a target clock frequency;
in step S608, the field frequency is adapted.
It should be noted that, when the field frequency changes, the flow will go to the calculation link; the recalculation is performed, again to obtain the appropriate clock frequency.
The method provided by the embodiment of the application selects the display parameters of the LED driving chip matched with the current field frequency through the software interface, however, the scheme in the related art is that the clock frequency of the LED driving chip under the specific field frequency is fixed, but the software in the scheme provided by the embodiment of the application needs to allow the user to input the clock frequency range of the data transmission of the LED driving chip instead of the fixed clock frequency.
