Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
In the exemplary embodiment, a method for locally adjusting an LED display screen is first provided. Referring to fig. 1 and 2, the local adjustment method may include the steps of:
step S101: selecting a local area to be adjusted in the whole display area;
step S102: acquiring attribute information of all lamp points in a local area;
step S103: selecting at least one lamp point to be adjusted from all lamp points in a local area, and adjusting the current attribute information of the at least one lamp point to be adjusted to target attribute information;
step S104: and sending the adjusted attribute information of the at least one lamp point to a control system of the LED display screen, wherein the adjusted attribute information is used for enabling the control system to control the display state update of the lamp point at the corresponding position of the at least one lamp point in the LED display screen.
It should be understood that the local adjustment method for the LED display screen refines the adjustment accuracy to the lamp points, and the method for adjusting the lamp points one by one enriches subsequent extensible application scenarios, for example, secondary adjustment can be performed on a local area with an unsatisfactory calibration effect after the whole screen is calibrated, or secondary processing can be performed on a poor effect of a partial area after the whole screen display screen effect is adjusted.
It should also be understood that the control system of the LED display screen has a receiving device, and the receiving device of the control system receives the adjusted attribute information, and then controls the display state of the lamp in the corresponding position in the LED display screen to update, for example, the input voltage of the lamp in the corresponding position in the LED display screen is controlled according to the received attribute information, and then the lamp is controlled to turn on or turn off.
It is also to be understood that before the local area to be adjusted in the total display area is selected, the area information corresponding to the total display area of the LED display screen has been acquired. The local adjusting method of the LED display screen can carry out secondary adjustment on the basis of the existing effect adjustment, because the function can be fully exerted after the whole screen adjustment (the whole screen adjustment such as calibration or display image quality adjustment) or the local adjustment on the basis of the existing display effect parameters. After the screen body configuration software builds a large screen, the lamp points in the local area can be adjusted to achieve the finely adjusted display effect.
It should also be understood that, referring to fig. 3, the local adjustment method for the LED display screen may be implemented by a remote terminal or by application software to implement the modified adjustment of the light points in the LED display screen. And the software displays all the lamp point information in the selected area and then is an editable item. After the lamp points are modified and judged to meet the expected requirements, the adjusted effect can be stored and solidified on the lamp panel of the LED display screen. The target attribute information is the attribute information when the adjusted lamp points in the LED display screen meet the expected requirements to achieve the optimal display effect.
According to the local adjusting method, the display effect of the local area can be adjusted more finely by adjusting the single lamp point in the display screen, and the display effect of the local area in the display screen can be adjusted, so that the problem that the local area is too bright or too dark is solved.
Next, the respective steps of the above-described control method in the present exemplary embodiment will be described in more detail with reference to fig. 1 to 3.
In one embodiment, referring to fig. 1, the method for locally adjusting the LED display screen further includes the following steps: judging whether the updated display state of the lamp points at the corresponding positions of the LED display screen meets the target attribute information or not; when the judgment is successful, the modified information is stored and the adjustment is completed; and when the target attribute information is judged not to be met, continuously adjusting the attribute information of the selected at least one lamp point. It should be understood that, because the fine tuning effect on the large screen can be seen instantly, the user can save and solidify the adjusted effect on the lamp panel when the adjusted effect can meet the current desired value. The adjustment to the lamp point relates to the adjustment that the data volume is originally less than the whole screen, and it is convenient to adjust and can in time see the response effect. The desired requirements are gradually met by continuing to make modifications when the desired requirements are not met.
In one embodiment, referring to fig. 1, the step S103 further includes the following steps: and selecting the attribute types to be adjusted of all the lamp points in the local area, and adjusting the attribute information of at least one selected lamp point according to the selected attribute types. It is to be understood that a variety of setting modes may be provided according to different service scenarios. For example, if the user selects the type of adjustment he wants to be the correction mode, the lamp point that needs to be adjusted currently can be selected from the displayed correction data. The attribute types to be modified can be set separately in different modes. By selecting the attribute type to be adjusted, switching to different attribute types for modification can be achieved.
In one embodiment, referring to fig. 1, the step S104 further includes the following steps: and displaying the lamp points at the corresponding positions of the LED display screen based on the adjusted attribute information. It should be understood that the existing parameters of the lamp point can be finely adjusted on the interface in the application software, and the result data after adjustment can be displayed on a large screen instantly. Because the selected lamp point data volume is small and can be fed back in time, the user experience can be greatly improved. The modified lamp points are displayed in real time, so that the modified display effect can be determined in time, and whether the current modification meets the expected requirement or not can be determined more conveniently.
In one embodiment, referring to fig. 1, the step S104 further includes the following steps: the adjusted attribute information comprises position information, and a control system of the LED display screen determines the corresponding position of at least one lamp point to be updated in the LED display screen according to the received position information of the at least one lamp point. It should be understood that the LED display screen can determine the position of the lamp point in time by sending the position information of the lamp point to be modified.
In one embodiment, step S103 further includes the following steps: selecting at least one lamp point to be adjusted from all lamp points in the local area according to the selected modification mode; the modification mode includes a single point modification mode and a batch modification mode. It should be understood that two modes can be set for the selection of the light point in the application software: one is single selection, which is convenient for adjusting the dead point of the lamp panel or adjusting the limit boundary points such as side seams and the like; and the other is batch selection, which facilitates simultaneous adjustment of a plurality of lamp points with consistent expected display effect. The efficiency of modifying the lamp points is improved by selecting the single-point modification mode or the batch modification mode.
In one embodiment, the attribute information includes at least one type of information of an adjustment correction coefficient, a color temperature value of the lamp point, and a brightness value of the lamp point. It should be understood that the specific parameter mode can be selected by choice, and the variety and practicability of the lamp point modification are increased by using a plurality of types of attribute information.
In one embodiment, step S101 further includes the following steps: and sending the position information of the selected local area to a control system of the LED display screen, and identifying the selected local area on the LED display screen. It should be understood that an operator can select a light point according to an existing display effect and a corresponding display area on the large screen can be identified, so that positioning and subsequent adjustment effects can be conveniently checked.
The invention will be described in more detail by way of a specific example, with reference to the above examples:
referring to fig. 1 and 3, the effect adjustment for a single lamp point is realized by combining software and hardware. Firstly, a user configures an LED display large screen, and selects a local area to be adjusted in the current large screen through configuration software; the software provides location information that reveals all the light points in the selected area and provides a variety of setting modes depending on different business scenarios. The user selects the type of adjustment he wants, such as the correction mode, can select the lamp point which needs to be adjusted currently in the displayed correction data, and then sets the data of the current lamp point through fine adjustment. After the software interface sets the data, the data carrying the lamp point position information is sent to the hardware system, the receiving card corresponding to the lamp point can rapidly analyze the adjusted parameters of the lamp point and apply the parameters, and the adjusted display effect is displayed on a large screen. According to the adjusting effect, the effect parameters can be stored, for example, after the local calibration coefficients are modified by the second fine adjustment, the modified coefficients can be issued by the storage function and cured.
Further, in the present exemplary embodiment, a virtual device for implementing the above method is also provided. The virtual device may include a virtual module that implements each step of the above method, respectively. It is to be understood that the first and second,
the specific manner in which the various modules perform operations has been described in detail in relation to embodiments of the method and will not be elaborated upon here.
