Detailed ways

In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application.

Firmware is the software that is responsible for the most basic and low-level work of a system. It refers to the device "driver" stored inside the device. Through firmware, the operating system can implement the operation of a specific machine in accordance with the standard device driver. For example, for the touch screen of an electronic device, firmware can be loaded into the memory of the touch screen to drive the touch screen, so that various touch operations can be performed on the touch screen. The touch screen memory is the memory of the touch screen system and is used to store data related to the operation of the touch screen.

The inventor found that the response of the touch screen of some electronic devices lags behind when the screen is turned on. For example, there is a significant time difference between the time when the screen of an electronic device is actually turned on and the time for the user to turn on the screen, which greatly affects the user experience.

After studying the problem of screen lag in some electronic devices, the inventor found that electronic devices with screen lagging are usually touch screen storage without flash memory. This type of electronic equipment When the screen is on, the terminal system needs to load the firmware to the touch screen memory. However, because the touch screen can support more functions, the firmware loaded into the touch screen memory is larger, and the communication interface rate during the loading process is limited, and the loading time process causes the touch screen to lag behind.

In order to solve this problem, the inventor further researched and found that there may be more than one working mode of the touch screen, for example, there may be a normal use mode of the user, a test mode for a developer to test the performance of the touch screen, a working mode corresponding to a bright screen, The working mode corresponding to the off screen, etc. The touch screen firmware of different working modes is usually integrated together as a firmware file. The firmware file is relatively large and takes too long to load. In different working modes, the touch screen firmware of the electronic device actually uses different touch screen firmware. That is to say, in one working mode, the firmware file of the loaded touch screen includes the touch screen firmware of all working modes.

Therefore, the inventor proposes the touch screen firmware loading method of the embodiment of the present application. When the working mode of the touch screen is switched, the touch screen firmware corresponding to the current working mode is loaded into the touch screen memory, which reduces the size of the firmware loaded into the touch screen memory. , Improve the loading speed. The method, device, electronic equipment, and storage medium for loading the touch screen firmware provided in the embodiments of the present application will be described in detail below through specific embodiments.

Please refer to FIG. 1, which shows a method for loading firmware of a touch screen provided by an embodiment of the present application. This method can be applied to the central processing unit of an electronic device. The embodiment of the present application takes a mobile phone as an example for description. Specifically, the method includes:

Step S110: Detect whether the working mode of the touch screen is switched.

In different working modes, the touch screen responds differently to touch operations on the touch screen, and is driven by different touch screen firmware. Therefore, it can be detected whether the working mode of the touch screen has been switched.

Step S120: If the working mode of the touch screen is switched, obtain the touch screen firmware corresponding to the current working mode as the firmware to be loaded, where different working modes of the touch screen correspond to different touch screen firmware.

In the touch screen memory, the touch screen firmware of the working mode is stored. When the working mode is switched, the touch screen firmware of the new working mode can be used to drive the touch screen. Therefore, after the working mode is switched, the touch screen firmware corresponding to the current working mode can be obtained, that is, the touch screen firmware of the switched working mode can be obtained. In the embodiment of the present application, for ease of description, the acquired touch screen firmware corresponding to the current working mode is defined as the firmware to be loaded.

Step S130: Load the firmware to be loaded into the touch screen memory.

The touch screen firmware of the current working mode is loaded into the touch screen memory, and the loaded touch screen firmware drives the touch screen to react to the touch operation in the current working mode.

In the embodiment of this application, since only the touch screen firmware of the current working mode is loaded into the touch screen memory when the working mode is switched, there is no need to load firmware files that support all working modes of the touch screen into the touch screen memory, which reduces the loading time and improves The response speed of the touch screen.

Another embodiment of the present application provides a method for loading firmware of a touch screen. In the method for loading the firmware of the touch screen in this embodiment, the firmware files corresponding to different working modes are obtained by splitting the firmware files. Specifically, please refer to Figure 2. The method includes:

Step S210: Split the firmware file to obtain the touch screen firmware corresponding to different mode identifiers.

The electronic device can obtain the firmware file used to drive the touch screen and store the system memory. The firmware file includes the firmware that drives all the working modes of the touch screen, that is, all the touch screen firmware corresponding to all the working modes of the touch screen are used as a firmware file Stored in system memory. Among them, the system memory is electrically connected to the central processing unit, which is different from the touch screen memory.

The electronic device may obtain the firmware file from the server. For example, when the electronic device is upgraded, the firmware file for the upgraded version of the touch screen driver is obtained from the server; the electronic device may also obtain the firmware file from other electronic devices.

After the electronic device obtains the firmware file, since the firmware file includes the touch screen firmware of each working mode, the firmware file can be split to obtain the touch screen firmware corresponding to each working mode.

In the embodiment of the present application, different working modes correspond to different mode identifiers, that is, the mode identifiers correspond to the working modes one-to-one, and the mode identifier corresponding to the working mode indicates the identity of the working mode. Therefore, after the firmware is split, the touch screen firmware corresponding to different mode identifiers can be obtained.

In the embodiment of the present application, the data of the touch screen firmware in the same working mode in the firmware file may be stored adjacently. The way to split the firmware file can be to read from the beginning of the firmware file and obtain the size of the currently read touch screen firmware. During the reading process, it is detected whether the size of the read file is equal to the size of the currently read touch screen firmware.

If the currently read file is not equal to the size of the currently read touch screen firmware, continue to read the firmware file until the currently read file is equal to the size of the currently read touch screen firmware. If the currently read file is equal to the size of the currently read touch screen firmware, the currently read touch screen firmware can be split from the firmware file to obtain a split touch screen firmware. And continue to read the remaining firmware files until the reading of the firmware files is completed.

For example, Figure 3 shows the firmware file. In the firmware file, A and B are in different working modes. The touch screen firmware A starts from a1 to an end, and the touch screen firmware B starts from b1 to bn. Read from the beginning of the firmware file, that is, read from a1. During the reading process, it is detected whether the size of the read file is equal to the size of the touch screen firmware A. When an is read, it can be detected that the size of the read file is equal to the size of the touch screen firmware A, and then the file A is split from the firmware file to obtain the touch screen firmware A. Continue to read the remaining firmware files from b1, and when bn is read, it can be detected that the size of the read file is equal to the size of the touch screen firmware B, then file B is split from the firmware file to obtain Touch screen firmware B.

Optionally, in the first implementation manner, if the sizes of the touch screen firmware in different working modes are the same, the size of the touch screen firmware in each working mode can be determined according to the size of the firmware file and the number of working modes.

Optionally, in the second implementation manner, the size of the touch screen firmware of each working mode may be different. The size of the touch screen firmware can be stored in the relevant field at the beginning of each touch screen firmware in the firmware file, and then in the process of reading the firmware file, it can be determined whether the size of the read file is equal to the touch screen being read The size of the firmware.

Optionally, in the third embodiment, the touch screen firmware of each working mode may have a unique firmware identifier, and there may be a configuration file to store the correspondence between different firmware identifiers and the size of the touch screen firmware, and the data size corresponding to each firmware identifier Equal to the size of the touch screen firmware corresponding to the firmware identifier. In the firmware file, the firmware identification of the touch screen firmware is stored in the relevant field at the beginning of each touch screen firmware. According to the firmware identification, the size of the touch screen firmware being read can be obtained, so that it can be determined whether the read file is equal to the normal reading. Take the size of the touch screen firmware.

In addition, in the embodiment of the present application, after the firmware file is split, the touch screen firmware corresponding to different mode identifiers can be obtained.

In one embodiment, the data of the touch screen firmware is different in different working modes, and the firmware size of different touch screen firmware is different. Therefore, the corresponding relationship between the mode identification of different working modes and the size of the firmware can be set, and each mode identification The corresponding firmware size indicates the size of the touch screen firmware identified by the mode. Therefore, the mode identifier corresponding to each touch screen firmware can be determined according to the corresponding relationship between the mode identifier and the size of the firmware, and the size of each touch screen firmware that is separated.

In another embodiment, each of the separated touch screen firmware includes a firmware identifier of the touch screen firmware. In addition, a configuration file of the corresponding relationship between the firmware identification and the mode identification is stored. Therefore, the firmware identification of each touch screen firmware can be obtained, and the mode identification corresponding to each touch screen firmware can be determined according to the corresponding relationship between the firmware identification and the mode identification, so as to determine the touch screen firmware corresponding to each working mode.

In the embodiment of the present application, when the firmware file is updated, the new firmware file needs to be split again. Therefore, it can also detect whether a new firmware file is obtained. If a new firmware file is obtained, the touch screen firmware corresponding to each mode identifier is re-determined according to the new firmware file.

In an implementation manner, when a new firmware file is obtained, the firmware file may be split again to obtain each of the split touch screen firmware. Then update the touch screen firmware corresponding to the mode mark. For the specific implementation of this implementation manner, reference may be made to the foregoing embodiments, and details are not described herein again.

In another embodiment, after the firmware file is updated, not all of the touch screen firmware may be updated. Therefore, the corresponding relationship with the mode identification may be re-established only for the updated touch screen firmware.

Specifically, in this embodiment, the updated part in the new firmware file can be determined. The updated part may belong to one touch screen firmware or multiple touch screen firmwares, and the touch screen firmware corresponding to the updated part can be separated from the new firmware file. The touch screen firmware corresponding to the update part, that is, the touch screen firmware to which the update part belongs.

The only correspondence between the split touch screen firmware and the mode identification is established, and the correspondence between the corresponding mode identification and the old touch screen firmware is overwritten or cancelled.

For example, as shown in Figure 4, in the new firmware file, the firmware data in the interval a4 to a5 is updated, and it can be determined that the firmware data in the interval a4 to a5 is the data of the touch screen firmware A, and then from the new firmware file, Split the touch screen firmware A, and establish a unique correspondence between the touch screen firmware A and the mode identification of the corresponding working mode. The touch screen firmware that is not updated in the firmware file can no longer be split from the touch screen firmware.

In the embodiment of the present application, after the firmware file is split into each touch screen firmware, the obtained touch screen firmware can be used to load into the touch screen memory in subsequent steps. In the case that the firmware file has not been updated, this step may no longer be executed, but the steps from step S220 to step S240 are executed cyclically.

Step S220: Detect whether the working mode of the touch screen is switched.

In the embodiments of the present application, the mode switching trigger may be the user's triggering mode switching operation on the touch screen, such as the trigger switching from the use mode to the test mode; the mode switching trigger may also be received through a hardware interface electrically connected to the outside Switching operation, such as when it is detected that a test device is connected through the hardware interface, enter the test mode, when it is detected that the test device is unplugged from the hardware interface, exit the test mode and enter the use mode; the trigger of the mode switch can also be through The wireless data transmission receives the switching instruction; the mode switching method can also be that the electronic device has a physical control to receive the switching operation, such as switching on or off the screen through the power button of the electronic device. When the electronic device is switched from on to on When the screen is off, the working mode is switched from the working mode under the bright screen to the working mode under the off screen, the electronic device is switched from the off screen to the bright screen, and the working mode is switched from the working mode under the off screen to the working mode under the bright screen. mode. The trigger of the specific mode switching is not limited in the embodiment of the present application.

In the embodiment of the present application, whether the working mode is switched can be detected, and when the switching of the working mode is detected, the switched working mode can be obtained.

The specific detection method is not limited in the embodiment of the present application. As an implementation manner, when each mode switch is triggered, a broadcast may be sent to the broadcast management service, and the broadcast includes the switch event and the working mode after the switch. It can be determined whether the working mode of the touch screen is switched, and the working mode after the switching, according to whether the broadcasting manager receives the broadcasting of the mode switching.

As another implementation manner, the current working mode of the touch screen can be detected at a certain frequency. In each detection, it is determined whether the currently detected working mode is the same as the previously detected working mode. If the same, it means that there is no The work mode switch occurs; if they are not the same, it can be determined that the work mode of the touch screen is switched.

In addition, in some special cases, if the touch screen of the electronic device changes from the non-working mode to the working mode, it is also determined that the working mode is switched. For example, after the electronic device is turned on from the off state, it enters the working mode after being turned on, and it is determined that the working mode of the touch screen is switched.

Step S230: If the working mode of the touch screen is switched, the touch screen firmware corresponding to the current working mode is acquired as the firmware to be loaded according to the corresponding relationship between the mode identifier and the firmware of the touch screen.

The different working modes of the touch screen correspond to different touch screen firmware. After determining the mode switch and determining the current working mode, the touch screen firmware corresponding to the mode identification of the current working mode can be obtained according to the corresponding relationship between the mode identification and the touch screen firmware, which is defined as the firmware to be loaded. For example, in the corresponding relationship between the mode identification and the touch screen firmware, the mode identification M1 corresponds to the touch screen firmware m1, the mode identification M2 corresponds to the touch screen firmware m2, and the mode identification of the current working mode is M1, the firmware m1 to be loaded can be determined. Among them, it can be understood that the current working mode is the switched working mode.

Optionally, in this embodiment of the application, in order to determine whether there is touch screen firmware corresponding to the current working mode, before acquiring the touch screen firmware corresponding to the current working mode, it can be determined whether the touch screen firmware corresponding to the current working mode is stored. If so, you can get the touch screen firmware corresponding to the current working mode.

Wherein, the way of judging may be, if in the corresponding relationship between the mode identification and the touch screen firmware, it is judged whether there is a mode identification of the current working mode, and if so, it is judged that the current working mode corresponds to the touch screen firmware.

If the touch screen firmware corresponding to the current working mode is not stored, in one embodiment, a prompt message that the current working mode is not supported may be displayed. In another implementation manner, a firmware acquisition request may be initiated to the server for acquiring the touch screen firmware corresponding to the current working mode. Optionally, what the server returns may be a firmware file. The firmware file includes the touch screen firmware corresponding to the current working mode, as well as touch screen firmware in other working modes, then the received firmware file is split to obtain the corresponding working modes After the touch screen firmware is installed, obtain the touch screen firmware corresponding to the current working mode. Optionally, the server may return the touch screen firmware corresponding to the requested current working mode. If the touch screen firmware returned by the server is received, the touch screen firmware corresponding to the current working mode may be obtained.

Step S240: Load the firmware to be loaded into the touch screen memory.

The central processing unit loads the firmware to be loaded into the touch screen memory. Specifically, the terminal system of the electronic device may load the firmware to be loaded into the touch screen memory. The touch screen firmware stored in the touch screen memory is updated to the touch screen firmware of the current working mode.

In the embodiment of the present application, the obtained firmware file is split to obtain the touch screen firmware corresponding to each working mode. When the working mode of the electronic device is switched, the touch screen firmware corresponding to the switched working mode can be obtained, and only the touch screen firmware of the switched working mode is loaded into the touch screen memory to increase the loading speed, thereby improving the response speed of the touch screen.

This application also provides an embodiment. In this embodiment, an example is given to illustrate how the touch screen firmware of an electronic device is loaded in a specific work mode switch. In this embodiment, the working mode of the touch screen may include a working mode when the screen is on and a working mode when the screen is off. The working mode under the bright screen is the feedback of the touch screen to the touch operation when the electronic device is in the on-screen state; the working mode under the off screen is the feedback of the touch screen to the touch operation when the electronic device is in the off-screen state, such as when the screen is off Gesture wake-up function. Specifically, in this embodiment, the method for loading the touch screen firmware specifically includes:

Step S310: Detect whether the on-off state of the touch screen is switched. If the on-off state of the touch screen is switched, it is determined that the working mode of the touch screen is switched.

The touch screen includes a working mode when the screen is on and a working mode when the screen is off. Then, it can be determined whether the working mode of the touch screen is switched according to the on and off state of the touch screen.

If the touch screen is switched from bright screen to off screen, it is determined that the working mode is switched from bright screen working mode to off screen working mode; if the touch screen is switched from off screen to bright screen, it is determined that the working mode is switched from off screen working mode to off screen working mode. Bright screen working mode.

Optionally, the electronic device needs to perform a touch screen performance test before leaving the factory, and may also need to perform a touch screen performance test during after-sales testing and maintenance. In this embodiment of the application, the touch screen may also have a test mode for performance testing and The usage mode used by ordinary users. In addition, the test mode can be divided into the test mode under the bright screen and the test mode under the off-screen state; the use mode can be divided into the use mode under the bright screen and the use mode under the off-screen.

Therefore, in an embodiment, detecting whether the working mode of the touch screen is switched may include, if a test trigger operation is received and the screen is currently in a bright screen state, determining that the working mode of the touch screen is switched to a test mode under bright screen. If the test trigger operation is received and the screen is currently in the off-screen state, it is determined that the working mode of the touch screen is switched to the off-screen test mode. If the test exit operation is received and the screen is currently in the bright screen state, it is determined that the working mode of the touch screen is switched to the use mode under the bright screen. If the test exit operation is received and the screen is currently in the off-screen state, it is determined that the working mode of the touch screen is switched to the off-screen use mode. Among them, the test trigger operation is the operation of controlling the touch screen to enter the test mode, and the test exit operation is the operation of controlling the touch screen to exit the test mode and enter the use mode.

In this embodiment, the electronic device can receive the test trigger operation and the test exit operation through a hardware interface electrically connected to the outside, or can receive the test trigger operation and the test exit operation by receiving a wireless signal, so that it is no matter whether the screen is off or on. Status, can control the electronic device to switch between test mode and use mode.

In another embodiment, the test trigger operation and the test exit operation of the electronic device need to be triggered by related controls when the screen is turned on, then detecting whether the working mode of the touch screen is switched, which may include, if the test trigger operation is received, entering the light Test mode under the screen, and before receiving the test exit operation, if the touch screen is switched to the off-screen state, it enters the test mode under the off-screen state, and if it is switched from the off-screen state to the on-screen state, it enters the test mode under the on-screen state ; If the test exit operation is received, it will enter the use mode under the bright screen, and before the test trigger operation is received, if the touch screen is switched to the off-screen state, it enters the off-screen use mode, if the off-screen state is switched to on Screen status, then enter the use mode under bright screen.

Step S320: If the working mode of the touch screen is switched, obtain the touch screen firmware corresponding to the current working mode as the firmware to be loaded.

When the touch screen is switched from on to off, then the touch screen firmware in the working mode in the off state is obtained; if the touch screen has the off screen and switched to the on, then the touch screen firmware in the working mode in the on state is obtained.

If the working mode of the touch screen includes the test mode and use mode under the bright screen, the test mode and use mode under the off screen, and if the current working mode is the test mode under the bright screen, obtain the touch screen firmware of the test mode under the bright screen; If the current working mode is the use mode under bright screen, then obtain the touch screen firmware of the use mode under bright screen; if the current work mode is the use mode under the off-screen use mode, obtain the touch screen firmware of the use mode under off-screen mode; if the current working mode For the test mode in the off-screen mode, obtain the touch screen firmware in the off-screen test mode.

Step S330: Load the firmware to be loaded into the touch screen memory.

For this step, reference may be made to the steps corresponding to the foregoing embodiments, and details are not described herein again.

In addition, optionally, since the touch screen memory does not include flash memory, firmware needs to be loaded into the touch screen memory every time the screen is turned on, so that when firmware supporting all working modes of the touch screen is loaded into the touch screen memory, the screen lighting speed is affected. In the embodiment of the present application, the touch screen firmware is loaded into the touch screen memory according to the working mode, so as to avoid the influence on the screen lighting speed. If the touch screen memory includes flash memory, the firmware file in the flash memory can be directly read. Therefore, in the embodiment of the present application, it can be detected whether the touch screen memory of the electronic device includes flash memory; if there is no flash memory, the method of loading the touch screen firmware according to the switching of the working mode in the embodiment of the present application can be executed, for example, the detection of the touch screen can be executed. Whether the work mode is switched.

Of course, in the embodiment of this application, the detection of whether there is a flash memory may not be performed. If the electronic device stores a program that executes the method for loading firmware of the touch screen in the embodiment of this application, it is considered that the electronic device does not have flash memory, and it is divided into working modes. Load the touch screen firmware to the touch screen memory.

In the embodiment of the present application, when the touch screen is switched on and off, it can be determined that the working mode of the touch screen is switched, or a test trigger operation or a test exit operation is received, and it can also be determined that the working mode of the touch screen is switched. Obtain the touch screen firmware corresponding to the switched working mode and load it into the touch screen memory.

Step S340: If the touch screen is switched to the bright screen state, after loading the touch screen firmware of the current working mode into the touch screen memory, while the touch screen remains on, load the touch screen firmware of other working modes to the touch screen memory.

In this embodiment of the present application, step S340 may be used as an optional step. Since the touch screen firmware needs to be written to the touch screen memory when the screen is on, the current working mode of the touch screen firmware is first loaded into the touch screen memory when the screen is on, so that the touch screen firmware loaded into the touch screen memory will not be too large and improve Bright screen response speed.

In the process of keeping the screen on, after loading the touch screen firmware in the current working mode, you can continue to load the touch screen firmware in other working modes, so that when the touch screen is switched to other working modes, there is no need to load the touch screen firmware, which is faster Improve the processing speed of the touch screen.

In the embodiment where this step is selected and executed, it is possible to obtain the touch screen firmware corresponding to the current working mode and load it into the touch screen memory only when it is detected that the touch screen is switched from off to on.

Optionally, if the working mode of the touch screen includes the use mode and the test mode under the bright screen, the use mode and the test mode under the off screen, it may be that when the working mode of the touch screen is switched to the test mode under the bright screen, the After the touch screen firmware corresponding to the test mode under the bright screen is loaded into the touch screen memory, it is more likely that the touch screen will switch from the test mode under the bright screen to the use mode under the bright screen while the touch screen remains on. , The touch screen firmware corresponding to the usage mode under the bright screen can be loaded to the touch screen memory. In addition, if the working mode is switched during the screen lighting process, since the touch screen firmware of the switched working mode has been loaded into the touch screen memory, there is no need to load the touch screen firmware corresponding to the switched working mode to the touch screen memory.

When the working mode of the touch screen is switched to the test mode with the screen off, there is a higher possibility that the touch screen will be switched from the test mode under the off screen to the use mode under the off screen. You can change the touch screen firmware corresponding to the test mode under the off screen After being loaded into the touch screen memory, while the touch screen remains off, the touch screen firmware corresponding to the use mode under the off screen is loaded to the touch screen memory. Moreover, if the working mode is switched during the screen-off process, since the touch screen firmware of the switched working mode has been loaded into the touch screen memory, there is no need to load the touch screen firmware corresponding to the switched working mode to the touch screen memory.

After the touch screen firmware corresponding to the current working mode is loaded into the touch screen memory, before other working modes are switched to, the touch screen firmware of other working modes is loaded in advance to improve the response speed of the touch screen in each working mode.

The embodiment of the present application also provides a touch screen firmware loading device 400. Referring to FIG. 6, the device 400 may include a detection module 410 for detecting whether the working mode of the touch screen is switched; and a firmware obtaining module 420 for obtaining the touch screen firmware corresponding to the current working mode as a standby if the working mode of the touch screen is switched. Loading firmware, where different working modes of the touch screen correspond to different touch screen firmware; the loading module 430 is used to load the firmware to be loaded into the touch screen memory.

Optionally, in the embodiment of this application, different working modes may correspond to different mode identifiers. The firmware obtaining module 420 may be used to obtain the touch screen firmware corresponding to the current working mode according to the corresponding relationship between the mode identifier and the touch screen firmware.
