Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
In the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
At present, the use of terminals such as mobile phones is becoming more and more popular, and the terminals produced by the same manufacturer often have differences in the starting speed of the display screen, for the following reasons: because the terminal often has a large production capacity, in order to prevent the production risk caused by factors such as insufficient supply of the display screen provider, poor supply quality, sudden increase of supply price, and the like, when the terminal is produced, a plurality of different providers are often selected for the display screen, and even four to five different providers are sometimes selected for supply. This results in the possibility of using different display screens for the final manufactured terminal. In addition, when the display screen of the terminal is damaged to the after-sale repair point, the replaced display screen and the display screen of the terminal which is shipped from a factory can be display screens of different suppliers.
However, for the convenience of software integration, the same control software is used when the terminal produced by the same manufacturer refreshes the software, which requires adding display drivers of various possible suppliers to the control software, and the display can normally work only when the display drivers are correctly loaded.
In the related art, the terminal needs to sequentially load the display drivers of the various possible suppliers until the display drivers match the display used by the terminal. For example, there are three possible display screen providers for the terminal: supplier one, supplier two, and supplier three. The terminal loads the corresponding display screen drivers in sequence according to the sequence of the first supplier, the second supplier and the third supplier, if the terminal uses the display screen of the first supplier, the terminal can use the display screen by only loading the driver of the first supplier, if the terminal uses the display screen of the second supplier, the terminal fails when loading the driver of the first supplier and then loads the driver of the second supplier, and if the terminal uses the display screen of the third supplier, the terminal fails when loading the driver of the first supplier and then loads the driver of the second supplier until the driver of the third supplier is loaded and then can use the terminal. It can be seen that for the display screens supplied by multiple suppliers, the loading is fast only when the used display screen is arranged at the front, otherwise, the display screen driver used by the terminal can be successfully loaded after multiple loading failures are required; at present, the loading sequence of each provider driver is fixed (for example, the loading sequence of the provider drivers is arranged according to the time introduced by the provider or according to the supply amount possible by the provider), so that it is very likely that the display driver needs to be loaded many times before the correct display driver can be loaded, and the boot efficiency is low. A fast and efficient loading method for the display driver is not provided.
The embodiment of the application provides a loading method, a loading device, a terminal and a storage medium of a display screen driver, so as to solve the problems in the related art. According to the technical scheme, when a starting-up instruction is received, a hardware identifier of a display screen of a terminal is obtained, a panel identifier set corresponding to the hardware identifier is determined according to a preset corresponding relation, and a target display screen drive corresponding to a target panel identifier in the panel identifier set is loaded; the terminal can screen out part of the display screen driven panel identifications according to the hardware identifications, and only the display screen drives corresponding to the part of the display screen identifications are required to be sequentially loaded, so that the loading speed of the display screen drives is increased, and the starting efficiency is improved.

The terminal stores the corresponding relation between the panel identification and the software identification in advance, and determines the software identification corresponding to the target panel identification as the first software identification according to the corresponding relation between the panel identification and the software identification.
Optionally, the terminal stores a second correspondence between the hardware identifier, the software identifier, and the panel identifier in advance. In the embodiment of the application, the hardware identifier, the software identifier and the panel identifier have a one-to-one correspondence relationship.
The hardware identification is the identification of the hardware of the display screen, and the software identification is the identification of the control software of the display screen. The panel identification is an identification of the display screen drive and is used for uniquely indicating the display screen drive in the n display screen drives.
In one possible implementation, the second correspondence between the hardware identifier, the software identifier and the panel identifier is as shown in fig. 4. When the hardware is marked as "11" and the software is marked as "0 x 00", the corresponding PANEL is marked as "PANEL-A", and the type of the display screen driver is "IC-A" at the time; when the hardware is marked as "11" and the software is marked as "0 x 01", the corresponding PANEL is marked as "PANEL-B", and the type of the display screen driver is "IC-A" at the time; when the hardware is marked as "10" and the software is marked as "0 x 02", the corresponding PANEL is marked as "PANEL-C", and the type of the display screen driver is "IC-B" at the time; when the hardware is marked as "10" and the software is marked as "0 x 00", the corresponding PANEL is marked as "PANEL-D", and the type of the display screen driver is "IC-B" at the time; when the hardware is marked as '01' and the software is marked as '0 x 03', the corresponding PANEL is marked as 'PANEL-E', and the type of the display screen drive is 'IC-C'; when the hardware is marked as '01' and the software is marked as '0 x 04', the corresponding PANEL is marked as 'PANEL-F', and the type of the display screen drive is 'IC-D'; when the hardware is marked as '00' and the software is marked as '0 x 01', the corresponding panel is marked as 'PANE L-G', and the type of the display screen drive is 'IC-E' at the moment; when the hardware is labeled "00" and the software is labeled "0 x 05", the corresponding PANEL is labeled "PANEL-H", and the type of display driver at this time is "IC-F".
Optionally, there are at least two panel identifiers corresponding to the same hardware identifier, that is, there is a same hardware identifier corresponding to different panel identifiers.
Optionally, the hardware identifiers of at least two display screen drivers are the same, that is, the same hardware identifier corresponds to different display screen drivers.
Optionally, at least two panel identifiers are the same, that is, the same software identifier is different from the different panel identifiers.
Therefore, the panel identifier of the display screen drive cannot be uniquely determined only by the hardware identifier, and the panel identifier of the display screen drive cannot be uniquely determined only by the software identifier. Because the hardware identification, the software identification and the panel identification have a one-to-one correspondence relationship, the panel identification driven by the display screen can be uniquely determined in a mode of 'hardware identification + software identification'.
And step 306, stopping loading when the target display screen driver is loaded successfully.
Optionally, when the second software identifier is consistent with the first software identifier, the terminal determines that the target display screen driver is successfully loaded, and stops loading.
And 307, judging whether i is smaller than m or not when the loading of the target display screen driver fails.
Optionally, when the second software identifier is inconsistent with the first software identifier, the terminal determines that the target display screen drive fails to be loaded, the terminal determines whether i is smaller than m at this time, and if i is smaller than m, the step 308 is executed; if i is equal to m, the process ends.
It should be noted that, step 306 and step 307 are two parallel steps, and one of the steps is executed alternatively, that is, there is no sequential execution order between step 306 and step 307.
And 308, when i is smaller than m, adding 1 to i, redetermining the ith panel identifier in the panel identifier set as the target panel identifier, and continuously executing the step of loading the target display screen driver corresponding to the target panel identifier.
Optionally, when i is smaller than n, the terminal adds 1 to i, redetermines the ith panel identifier in the panel identifier set as the target panel identifier, and continues to execute step 304.
Optionally, the terminal determines the target display screen driver successfully loaded as the candidate display screen driver, loads the candidate display screen driver when the start instruction is received next time, and executes the step of obtaining the hardware identifier of the display screen of the terminal again when the candidate display screen driver fails to be loaded.
Schematically, when the terminal receives a starting-up instruction next time, the candidate display screen driver is loaded first, and if the loading is successful, the loading is stopped; if the loading fails, step 301 is executed again according to the loading method of the display screen driver provided in the embodiment of the present application.
In an illustrative example, based on the correspondence relationship provided in fig. 4, when the terminal receives the power-on instruction, the hardware identifier of the display screen is acquired as "00", and the terminal acquires a PANEL identifier set corresponding to the hardware identifier "00", where the PANEL identifier set includes a PANEL identifier "PANEL-G" and a PANEL identifier "PANEL-H". The terminal determines a first PANEL identification 'PANEL-G' in the PANEL identification set as a target PANEL identification, acquires a pre-stored configuration file, determines a sequence number 'A [7 ]' corresponding to the target PANEL identification 'PANEL-G' in the configuration file as a target sequence number, and loads a target display screen drive in a memory indicated by the target sequence number 'A [7 ]'. The terminal acquires a second software identifier '0X 01' of the candidate display screen driver corresponding to the target PANEL identifier 'PANEL-G', and determines that the target display screen driver is successfully loaded when the second software identifier '0X 01' is consistent with the first software identifier '0X 01'. In the related art, if the display screen driver corresponding to the PANEL identifier "PANEL-G" needs to be loaded when the terminal is turned on, the display screen driver needs to be loaded seven times because the loading sequence of the display screen driver is the seventh, and the display screen driver loading method provided by the embodiment of the present application can be loaded successfully only once.
To sum up, the embodiment of the application also pre-stores the one-to-one correspondence relationship among the hardware identifier, the software identifier and the panel identifier in the terminal, so that the terminal can uniquely determine the panel identifier driven by the display screen in a mode of 'hardware identifier + software identifier', thereby improving the loading speed of the display drive and ensuring the loading accuracy of the display drive.
According to the method and the device, the target display screen driver which is loaded successfully is determined as the candidate display screen driver, and the candidate display screen driver is loaded when the starting instruction is received next time, so that the display screen driver corresponding to the display screen used by the terminal can be loaded first when the terminal is started, the loading speed of the display screen driver is effectively increased, and the starting time length during subsequent starting is shortened.
