Embodiment 1

[0042] This embodiment provides a touch screen upgrade method, which is suitable for a touch screen upgrade device. Through the backup upgrade function pre-stored in the touch screen upgrade device, when the touch screen fails to work normally, the touch screen upgrade device uses the backup upgrade function to upgrade the touch screen. to allow the touchscreen to resume normal operation. The touch screen upgrading device can be set in the touch screen, for example, integrated on an internal chip of the touch screen, or can be set separately.

[0043] Such as figure 1 As shown, it is a schematic flow chart of the touch screen upgrading method of this embodiment, including:

[0044] Step 101, when an upgrade instruction is received, an upgrade function of a control module of the touch screen is called to perform an upgrade operation.

[0045] Specifically, when upgrading the touch screen, the upgrade file is first sent to the memory of the mobile phone that contains the touch...

Embodiment 2

[0058] The second embodiment further improves the touch screen upgrading method in the first embodiment.

[0059] In this embodiment, it also includes, when it is recognized that the touch screen is in a normal working state:

[0060] Step a, determine whether the version value of the internal program in the control module is consistent with the version value of the upgrade program, if so, return an upgrade success response, otherwise generate an upgrade failure response;

[0061] Step b, exit the upgrade function.

[0062] In this embodiment, before step 101, it also includes: when the upgrade module of the touch screen receives an instruction and needs to upgrade, it first detects whether the upgrade file is legal, and when the detection result is legal, calls the upgrade function to input to the control module of the touch screen The operation of the upgrade function, otherwise, it is forbidden to call the upgrade file. This is because in the upgrade file, many files may c...

Embodiment 3

[0065] This embodiment further improves the touch screen upgrading method in the foregoing embodiments.

[0066] Specifically, after inputting the internal program obtained after parsing into the touch screen control module to perform the upgrading operation of the internal program, it also includes:

[0067] Identify whether the touch screen is in a normal working state, if so, return a successful response, and exit the backup upgrade function, if not, repeat the upgrade operation of the internal program until the set number of times is reached.

[0068] Other steps in this embodiment are consistent with the touch screen upgrading method in the above embodiments, and will not be repeated here.

[0069] In the touch screen upgrade method of this embodiment, after the touch screen calls the backup upgrade function to perform the upgrade operation, it can detect whether the touch screen is in a normal working state, and when the detection result is yes, exit the backup upgrade f...

Abstract

The invention provides a method and a device for upgrading a touch screen. The method comprises the following steps of: when an upgrading instruction is received, calling the upgrading function of a control module of the touch screen to perform upgrading operation; when the abnormal working state of the touch screen is identified, sending a resetting instruction to the control module to reset the touch screen; and calling a standby upgrading function to acquire a standby upgrading file for resolving from the control module, and inputting the resolved internal program to the control module to perform the upgrading operation of the internal program. According to the method and the device for upgrading the touch screen, when the upgrade of the touch screen fails, the touch screen can be reused by calling the standby upgrading function, so that an intelligent mobile phone can be used.

Description

technical field [0001] The invention relates to communication technology, in particular to a touch screen upgrading method and device. Background technique [0002] With the widespread use of smart phones, touch screens play an increasingly critical role. [0003] The internal program of the touch screen chip uses the analog signal detected by the touch screen to calculate the digital signal required by the mobile phone driver and complete some complex calculations such as signal filtering. The internal program of the touch screen chip also needs to be updated synchronously. There are mainly two ways to upgrade the internal program of the existing touch screen chip, one is to directly connect the touch screen to upgrade after disassembling the smartphone with a special fixture, and the other is to use the mobile phone driver to transmit data through the bus to upgrade when it is turned on. [0004] However, the former method is very inconvenient, requiring professional per...
