Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in 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 implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
In the production process of the terminal, due to the problem of source of goods, two or more models are often adopted to assemble the terminal for the same type of hardware module. For hardware modules of different models, developers need to design different logics, so that the hardware module can be adapted to other hardware modules, and further normal use of the terminal is not affected. Correspondingly, in the process of starting up the terminal, each hardware module also needs to identify the hardware models of other hardware modules so as to adopt corresponding logic for adaptation.
Among them, in a terminal operated through a touch screen, identification of a display module is very important. Especially, the hardware model of the display module can be identified by the touch module to adapt the display module, otherwise, the terminal cannot be normally used due to the fact that the touch module is not adapted to the display module.
In the related art, a GPIO (General-purpose input/output) interface is usually required to be additionally reserved in the terminal, and the display module is connected to the GPIO interface, so that other hardware modules can determine the model of the display module according to the voltage value detected by the GPIO interface. Obviously, the method needs to reserve additional GPIO interface, which not only increases hardware cost, but also occupies internal space of the terminal, reduces available design space in the terminal, and further increases difficulty of hardware design.
Therefore, the disclosure provides a display module identification method to avoid the problems that the cost of terminal hardware is increased and the internal space of the terminal is occupied due to the fact that a GPIO interface needs to be additionally reserved in a terminal in the related technology.
Fig. 1 is a diagram illustrating a display module identification method according to an exemplary embodiment of the disclosure. As shown in fig. 1, the method may include the steps of:
102, reading a hardware information character string by a display module of the terminal, and analyzing the hardware information character string to obtain a target model parameter corresponding to the display module, wherein the model parameter of each hardware module in the terminal is recorded in the hardware information character string.
In the present disclosure, the display module and the touch module are hardware modules rather than logic modules. In the field of touch control, a touch screen of a terminal usually includes a plurality of layers superimposed on each other. The touch screen comprises a display layer and a touch layer. The display module in the present disclosure refers to the display layer, and the touch module refers to the touch layer.
As can be seen from the above, in the related art, a GPIO interface needs to be reserved inside the terminal for identifying the display module. Specifically, the display module can be connected with the GPIO interface, when the touch module needs to identify the hardware model of the display module, the touch module can read the voltage value detected by the GPIO interface, and the hardware model of the display module is determined according to the voltage value. For example, when the voltage value is high voltage, the hardware model of the display module is determined to be model A; and when the voltage value is low voltage, determining that the hardware signal of the display module is type B. Obviously, the method needs a certain hardware foundation, and hardware cost is increased.
In view of this, the present disclosure does not use the GPIO interface to identify the display module, but identifies the display module on a software level. Specifically, under the condition that the terminal is started, the central processing unit of the terminal can store the pre-stored hardware information character strings recorded with the model parameters of each hardware module into the memory, so that the display module can extract the hardware information character strings from the memory and identify and obtain the target model parameters for representing the hardware model of the display module. On the basis, the display module can store the target model parameter into a preset calling variable with access authority of the touch module. Then, when the touch module needs to identify the hardware model of the display module to carry out fitting, the target model parameter can be obtained from the calling variable, and then the hardware model of the display module is identified. Obviously, according to the method and the device, only the target model parameter for representing the hardware model of the display module needs to be identified from the hardware information character string and stored into the preset calling variable, the touch module can determine the hardware model of the display module by accessing the calling variable, and the problems that in the related technology, the hardware cost is high and the internal space is occupied due to the fact that the GPIO interface needs to be reserved are solved.
In this disclosure, not all variables in the memory may be accessible to the hardware module, and based on this, the central processing unit should store the hardware information character string in the variable having the access right of the display module after determining that the terminal is started and obtains the pre-recorded hardware information character string. For example, the hardware information character string may be saved in a system environment variable of a memory, and the character string saved in the system environment variable may be called by each hardware module in the terminal. On the basis, the display module can read the hardware information character string from the system environment variable and further analyze the hardware information character string to obtain a target model parameter for representing the hardware model of the display module.
In this disclosure, any character string recorded with the hardware model of each hardware module may be used as a hardware information character string, for example, when a developer designs a terminal, the developer usually debugs each hardware module of the terminal continuously, and records the hardware information of each hardware module in cmdline, and a parameter value in the variable is also corrected continuously along with the debugging of the developer until the final design of the terminal is determined, and the terminal enters a production stage. Therefore, the parameter value stored in the cmdline variable is stable after the cmdline enters the production phase, and therefore, the cmdline value stored in the cmdline variable can be used as the hardware information character string in the present disclosure.
And step 104, the display module of the terminal stores the target model parameter into a preset calling variable.
In the present disclosure, after the hardware information character string is stored in the memory, the hardware information character string can be read by the display module to determine the hardware type of the display module. The hardware information of each hardware module is recorded in the hardware information character string, so that after the hardware information character string is read by the display module, the hardware information character string can be analyzed to obtain a target model parameter for representing the hardware type of the display module, for example, the model parameter of each hardware module is usually recorded in a fixed character segment of the hardware information character string, so that when the hardware information character string is analyzed by the display module, the character segment recorded with the information of the display module can be preferentially determined, characters recorded in the character segment can be read out, and the read characters are the target model parameter for representing the hardware type of the display module. The display module in this disclosure can save the target model parameter obtained by the analysis to any variable that can be accessed by the touch module, so that the touch module reads the target model parameter from the variable to identify the hardware model of the display module. Since the variable is used for storing the target model parameter to be called (or read) by the touch module, the variable is named as a calling variable and can be predefined by a developer.
In practical applications, since the touch module needs to have the right to access the call variable, the display module can store the target model parameter into the call variable through the export _ symbol method. The parameter value stored by the method is added with an export _ symbol identifier, the parameter value added with the identifier is disclosed for all kernel codes, namely, any hardware module in the terminal can call a variable with the identifier in the process of executing the codes. In other words, the target model parameter stored by the export _ symbol method enables each hardware module including the touch module to have the right to call the target model parameter by accessing the call variable.
And 106, acquiring the target model parameter from the calling variable by the touch module of the terminal so as to identify the hardware model of the display module.
In the disclosure, after the display module in the terminal obtains the target model parameter through analysis, the hardware model of the terminal can be determined. On the basis, the operation required to be completed by the display module in the starting-up stage can be completed. For example, after determining the hardware model of the display module, the display module can obtain a driving code corresponding to the hardware model, and drive the display module by executing the driving code, so that the display module can realize functions such as screen lightening.
In addition, after the display module analyzes the target model parameter and stores the target model parameter to the calling variable, the touch module can call the target model parameter value by accessing the calling variable in the driving process, and further the hardware model of the display module is determined. On the basis, the touch module can acquire adaptive parameters matched with the hardware model of the display module and adapt to the display module; or the operation logic of the display module is adjusted to be matched with the display module.
Furthermore, besides the adaptation with the display module, the touch module can further adjust the driving code of the touch module according to the hardware model of the display module, and drives the touch module by executing the adjusted driving code. It is not difficult to understand that the touch module adjusts the driving code of the touch module, which is equivalent to adjusting the running logic of the touch module according to the hardware model of the display module, so as to ensure the stability of interaction between the touch module and the display module.
The execution subject of the technical solution of the present disclosure may be any type of terminal, for example, the terminal may be any one of a smart phone, a tablet Computer, a smart television, and a PC (Personal Computer). It should be understood that only a terminal configured with a touch screen may serve as an execution subject of the present disclosure, and specifically, which type of terminal is used as the execution subject of the present disclosure may be determined by those skilled in the art according to actual needs, and the present disclosure does not limit this.
According to the technical scheme, in the disclosure, under the condition that the central processing unit of the terminal determines that the terminal is started, the hardware information character strings recorded with the model parameters of each hardware module are stored in the memory, so that the display module of the terminal can read the hardware information character strings from the memory, and the target model parameters for representing the model of the display module are obtained in a manner of analyzing the hardware information character strings. On the basis, the display module can store the target model parameter into a calling variable with access authority of the touch module, so that the touch module can read the target model parameter from the calling variable, and further determine the hardware model of the display module.
It should be understood that, in the related art, a GPIO interface needs to be reserved in the terminal, and the display module needs to be connected to the GPIO interface, so that when the hardware model of the display module needs to be known, each hardware module in the terminal can determine the hardware model of the display module by reading the voltage value of the GPIO interface. However, with the adoption of the mode disclosed by the invention, the display module can read the hardware information character string and store the target model parameter obtained by analyzing the hardware information character string into the preset calling variable, so that when the hardware model of the display module needs to be determined, the touch module directly calls the target model parameter from the calling variable to determine the hardware model. Therefore, through the technical scheme disclosed by the invention, the GPIO interface does not need to be reserved to identify the model of the display module in the related technology, so that the hardware cost of the terminal is reduced, the space inside the terminal is saved, and the difficulty of hardware design is reduced.
Furthermore, after the display module in the present disclosure analyzes the hardware information character string to obtain the target model parameter, the target model parameter may be stored in the calling variable through the export _ symbol method, and since the parameter value stored through the export _ symbol method may be accessed by each hardware module, by the method, each hardware module in the terminal may call the target model parameter in a manner of accessing the calling variable when the hardware model of the display module needs to be identified, thereby determining the hardware model of the display module.
The disclosure also provides a display module identification method applied to the display module of the terminal. In the method, most operation modes of the display module, for example, where to read the hardware information character string, how to analyze the read hardware information character string, and the like, are similar to those of the previous embodiment, and therefore, details are not described in the next embodiment, and specific operation modes can refer to the description of the previous embodiment.
Fig. 2 is a flowchart illustrating another display module identification method according to an exemplary embodiment of the disclosure. As shown in fig. 2, the method comprises the steps of:
step 202, reading a hardware information character string; the hardware information character string records model parameters of each hardware module contained in the terminal.
As described above, after determining that the terminal is started and acquires the pre-recorded hardware information character string, the central processing unit may store the hardware information character string in the system environment variable of the memory, and the character string stored in the system environment variable may be called by each hardware module in the terminal. On the basis, the display module can read the hardware information character string from the system environment variable and further analyze to obtain a target model parameter for representing the hardware model of the display module.
As described above, the present disclosure may use the cmdlene value stored in the cmdlene variable as the hardware information string.
Step 204, analyzing the read hardware information character string to obtain a target model parameter corresponding to the display module, and storing the target model parameter into a preset calling variable, so that the touch module of the terminal can obtain the target model parameter from the calling variable, wherein the target model parameter is used by the touch module to identify the hardware model of the display module.
As described above, the display module may store the target model parameter into the call variable by using the export _ symbol method, so that each hardware module including the touch module has a right to call the target model parameter by accessing the call variable.
As described above, after determining the hardware model of the display module, the display module may obtain the driving code corresponding to the hardware model, and drive the display module by executing the driving code, so that the display module can realize functions such as screen brightening. In addition, the display module is in the target model parameter that will resolve to save to and call the variable after, the touch module can be through visiting this call variable at the driven in-process, in order to call the target model parameter value, and then confirms the hardware model of display module. On this basis, the touch module can acquire the adaptation parameter matched with the hardware model of the display module and adapt to the display module.
According to the technical scheme, through the technical scheme, the display module in the terminal only needs to read the hardware information character string and analyze the hardware information character string, and the target model parameter for representing the hardware model of the display module can be obtained. On the basis, the display module only needs to store the target model parameter into a calling variable with access authority of the touch module, and the touch module can read the target model parameter from the calling variable so as to determine the hardware model of the display module, thereby avoiding the problem of high hardware cost caused by the need of reserving a GPIO interface in the related technology.
In the following, a smart phone is taken as an example to introduce the technical scheme of the present disclosure.
Fig. 3 is a flowchart illustrating another display module identification method according to an exemplary embodiment of the disclosure. As shown in fig. 3, the method comprises the steps of:
step 301, the CPU acquires a cmdline value when it is determined that the smartphone is activated.
The smart phone usually includes hardware modules such as a motherboard, a CPU, a memory, a display module, and a touch module. The main board can include a power supply control module, when a user presses a power-on key for a long time, the power supply control module can detect the power-on signal and control the power supply to supply power to the CPU, so that the CPU starts to operate.
Step 302, the CPU saves the acquired cmdlene value to a system environment variable of the memory.
The cmdlene value in this embodiment may be stored in a memory space (i.e., in a ROM) of the smartphone in advance. After the CPU starts to operate, the cmdlene value can be read from the storage space, and the cmdlene value is stored in system environment variables of a memory (in an RAM), so that each hardware module in the smart phone can read the cmdlene value.
Step 303, the display module reads the cmdlene value from the system environment variable of the memory.
In this embodiment, after the display module starts to operate, the cmdlene value may be read from the system environment variable of the memory, and the cmdlene value may be analyzed to obtain a target model parameter for characterizing the hardware model of the display module.
For example, the display module may analyze the cmdlet value by calling a dsi _ display _ part _ cmdlet _ topology function, and the obtained target model parameter may be: qcom, mds _ dsi _ k9_36_02_0a _ p2_ dsc _ cmd.
And step 304, the display module analyzes the read cmdlene value to determine the target model parameter.
Step 305, the display module stores the target model parameter into the calling variable through the export _ symbol method.
After the target model parameter is obtained, the target model parameter can be stored in a calling variable.
Taking the above example, the calling variable may be a global _ panle _ info variable. Then, the target model parameter qcom, mdss _ dsi _ k9_36_02_0a _ p2_ dsc _ cmd, can be saved to the global _ pan _ info variable by the export _ symbol method. Of course, the naming of the calling variable can be determined according to actual requirements, and the disclosure does not limit the calling variable.
In step 306, the touch module accesses the call variable to read the target model parameter.
After the target model parameter is stored in the calling variable, the touch module can access the calling variable to obtain the target model parameter, and the hardware model of the display module is determined according to the target model parameter.
For the above example, the touch module can access the global _ tile _ info variable to read a target model parameter, qcom, mdss _ dsi _ k9_36_02_0a _ p2_ dsc _ cmd, and determine the model of the display module according to the target model parameter. For example, the character position of "36" in the target model parameter represents the hardware model of the display module, so that the touch module can determine the hardware model of the display module according to the two character values of "36". Assume that an originally designed smartphone will employ two display modules with hardware models a and B, where a character value "36" is used to represent model a and a character value "48" represents model B. Then, in this embodiment, the hardware model of the display module can be determined to be model a.
And 307, the touch module determines the hardware model of the display module according to the acquired target model parameter.
In this embodiment, after determining the hardware model of the display module, the touch module may adjust its own operating logic according to the hardware model to adapt to the display module.
According to the technical scheme, after the smart phone is started, the CPU can store the pre-stored cmdline value into the memory so that the display module can read the cmdline value and analyze the target model parameter to represent the hardware model of the smart phone. The display module can save the target model parameter obtained by analysis to a preset calling variable, on the basis, the touch module can identify the hardware model of the display module by accessing the calling variable, and then the display module is adapted, so that the problems that the hardware cost is increased due to the fact that GPIO interfaces are required to be reserved in the related technology and the design difficulty is increased are solved.
