The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
According to the method and the device, the picture display parameters are stored in the storage, and the picture display parameters stored in the storage can be updated, so that the picture display parameters can be updated to dynamically adjust the picture display effect until the requirements of users are met, different display effects can be realized on the same liquid crystal display device, the requirements of different users are met, products with different effects do not need to be purchased, and resources are saved.
Referring to fig. 2, fig. 2 is a first flowchart illustrating a screen display control method according to an embodiment of the present application, applied to the electronic device, including the following steps:
step 201: and receiving an image display parameter acquisition instruction.
When a user wants to control the display of a picture in a screen by changing the display parameters, the user sends a picture display parameter acquisition instruction to the electronic equipment, wherein the user can send the instruction through a remote controller, a mobile phone and other mobile controllers, or directly click a corresponding position on a UI (user interface) of the screen to generate the instruction.
In one embodiment, the step of receiving a screen display parameter acquisition instruction includes: and when detecting that a user triggers the opening operation of the picture display parameter switch, receiving a picture display parameter acquisition instruction corresponding to the opening operation.
For example: when the user turns on the screen display parameter switch of the UI menu, a screen display parameter acquisition instruction is generated.
And the electronic equipment receives the image display parameter acquisition instruction and then executes the next operation.
Step 202: and acquiring the picture display parameters from the storage module according to the picture display parameter acquisition instruction.
And after receiving the image display parameter acquisition instruction, the electronic equipment acquires the image display parameters from the storage module according to the image display parameter acquisition instruction.
In one embodiment, the step of obtaining the picture display parameters from the storage module according to the picture display parameter obtaining instruction includes:
determining a corresponding picture display parameter comparison table from the storage module according to the picture display parameter acquisition instruction; and determining the picture display parameters according to the picture display parameter comparison table.
The picture display parameters comprise a black insertion time parameter, a current parameter, a scanning parameter and a switch parameter, wherein the black insertion time parameter represents the time t for turning off the backlight of the screen.
The current parameter represents the amplification factor k of the current in the screen, and the overall brightness becomes lower due to the increase of the black insertion time, so that at this time, the current factor needs to be amplified properly, so that according to the principle of power conservation, since the ratio of the time for lighting the backlight to the original event is (T-T)/T, the maximum current factor that can be amplified is k ═ T/(T-T), where T is the period for updating the image of each frame.
The scan parameter indicates whether to scan line by line or N lines by line during scanning, that is: the embodiment is that 1 line of lamps are simultaneously lighted or N lines of lamps are simultaneously lighted on the backlight lamp; the switching parameter indicates whether the picture display parameter is applied to the current screen.
The switch parameter indicates whether or not the picture display parameter is applied to picture display of the screen.
Since the control module can only receive binary values, we specify the relevant variables as follows, the number of control lines of the vertical direction lamp is substituted directly with N, the black insertion time parameter is substituted with T/T100, and the current amplification factor k is substituted with T/(T-T0-T) 100 (this value is limited by the maximum current carried by the LED lamp). As shown in table 1, the current parameter, the black insertion time parameter, the scanning parameter, and the switching parameter are converted into binary values and stored in the frame display parameter comparison table, wherein the default of the reserved bit is 0, the value ranges of the current parameter, the black insertion time tea tree, and the scanning parameter are 0-FF, and the value of the switching parameter is 0 or 1.
TABLE 1 Picture display parameter comparison table
| Reserved bit | Current parameter | Black insertion time parameter | Scanning parameters | Switching parameter |
| Default is 0 | 0-FF | 0-FF | 0-FF | 0 or 1 |
Step 203: and sending the picture display parameters to the control module.
In one embodiment, the step of sending the screen display parameters to the control module includes: sending the picture display parameters to a driving module; binding the picture display parameters in an interface module through the driving module; and sending the picture display parameters to the control module through the interface module.
In the last step, after the electronic equipment acquires the picture display parameters, the picture display parameters are sent to the bottom layer of the driving module, and the driving module binds the picture display parameters in the interface module and then transmits the picture display parameters to the control module through the interface module.
Step 204: and controlling the picture display of the screen according to the picture display parameters through the control module.
After the electronic equipment in the last step sends the picture display parameters to the control module, the control module directly controls the working state of the backlight lamp according to the picture display parameters, and further controls the picture display of the screen according to the working state of the backlight lamp.
In one embodiment, the picture display parameter comprises a black insertion time parameter; the step of controlling the picture display of the screen according to the picture display parameters through the control module comprises the following steps: and controlling the picture effects of different areas in the screen according to the black insertion time parameter through the control module.
As shown in fig. 4, in the scan timing chart provided in the embodiment of the present application, in a normal case, the black insertion time parameter T is T/N, where T is a period for updating each frame of image, and N is a scan parameter, since liquid crystal scanning scans from top to bottom and from left to right, when T is T/N, the image definition in the screen is high and the image definition of each region in the screen is the same, when T is smaller than T/N, the image definition in the upper region in the screen is low and the image definition in the lower region in the screen is high, and when T is larger than T/N, the image definition in the upper region in the screen is high and the image definition in the lower region in the screen is low.
In one embodiment, the step of controlling, by the control module, the picture display of the screen according to the picture display parameter includes: receiving a picture display parameter application instruction, and sending the picture display parameter application instruction to the control module; and controlling the picture display of the screen according to the picture display parameters through the control module.
After the MCU black insertion time parameter, the current parameter, the scanning parameter and the switching parameter are configured into variables, after receiving an instruction that BFI is 1, namely an image display parameter application instruction, the received current amplification factor, black insertion time and line number information of the lamp in the vertical direction are converted into duty ratio of the lamp and current to act on each backlight lamp, and then image display effect is controlled.
The embodiment of the application provides a picture display control method, which comprises the steps of firstly receiving a picture display parameter acquisition instruction, then acquiring picture display parameters from a storage module according to the picture display parameter acquisition instruction, then sending the picture display parameters to a control module, and finally controlling picture display of a screen according to the picture display parameters through the control module. The picture display parameters are stored in the memory, and the picture display parameters stored in the memory can be updated, so that the picture display parameters can be updated to dynamically adjust the picture display effect until the requirements of a user are met. The picture display control method can achieve different display effects on the same liquid crystal display device, and meets the requirements of different users.

step 205: and receiving the picture display parameters uploaded by the developer terminal, and storing the picture display parameters in a storage module.
The developer terminal in the application can be a user terminal and can also be a developer terminal of a liquid crystal display device manufacturer, a user can adjust picture display parameters on the user terminal by himself and store the picture display parameters in the storage, the user can also adjust the picture display parameters through terminals such as a notebook computer and the like and upload the picture display parameters to a storage module of liquid crystal display equipment, and a worker for setting the liquid crystal display can also adjust the picture display parameters through the developer terminal and upload the picture display parameters to the storage module of the corresponding liquid crystal display equipment.
In one embodiment, the developer terminal uploads the picture display parameters to the cloud, the cloud server receives an acquisition request of the liquid crystal display device, and the cloud sends the picture display parameters to the corresponding liquid crystal display device.
The method and the device can upload the picture display parameters through the developer terminal, and when the currently applied picture display parameters do not meet the picture display requirements of users, the changed picture display parameters can be uploaded to the liquid crystal display device again through changing the picture display parameters and stored in the storage module of the liquid crystal display device, and the electronic equipment controls the picture display of the screen according to the updated picture display parameters.
