Since the hardware parameters of different types and sizes of displays are different, such as the size of the display, the resolution of the display, the timing of the display, the parity of the display, the brightness value of the display, etc., in many cases , the manufacturer does not need to make any modifications when changing the same display screen of the product, but when changing the different display screens of the product frequently, the manufacturer needs to invest a lot of time to compile the software to adjust the parameters of the display screen. When responsible for multiple products or multiple different display screens of a product at the same time, errors may occur in such a large amount of work
[0003] In the current existing technology, when the display device products use the same movement, as long as the size of the display is different, the type of the display is not the same, it is necessary for the manufacturer's technical personnel to compile a corresponding version of the software, resulting in the same movement configuration Seven, eight or even more than a dozen types of software will be compiled for different display screens, which will cause great trouble to product development, production and maintenance after the product is put on the market.

Embodiment 1
[0028] figure 1 , which shows a flowchart of a method for upgrading different display screens using the same set of software provided by Embodiment 1 of the present invention. The specific steps of the method are as follows:
[0029] Step S101, start the device, run the upgrade software, and read the value in the EEPROM;
[0030] More specifically, before the step S101, it also includes: entering the program initialization, initializing the value in the EEPROM, and initializing the upgrade software in the Nand Flash;
[0031] In the embodiment of the present invention, the upgrade software is initialized and stored in Nand flash (Nand flash memory), and the value is preset in EEPROM (Electrically-Erasable Programmable Read-Only Memory, Electrically Erasable Programmable Read-Only Memory), where the parameter value is 0-n, n is a positive integer;
[0032] In the product with the same screen, the screen parameters of the device are saved in the upgrade software in two places,...
Embodiment 2
[0058] Figure 5 , shows a schematic structural diagram of a system for upgrading different display screens using the same set of software in Embodiment 2 of the present invention. The system includes: a reading unit 51 , a changing unit 52 , a forced switching unit 53 and a loading unit 54 .
[0059] The reading unit 51 is used for running the upgrade software when the device is started, reading the value in the EEPROM, and judging whether the device starts normally.
[0060] The changing unit 52 is used to change the value in the EEPROM when the device starts normally, so that the screen model corresponding to the value is consistent with the current screen model of the device.
[0061] The forced switching unit 53 is used to forcibly change the value in the EEPROM when the device cannot be started normally, and rewrite the changed value into the EEPROM.
[0062] The loading unit 54 is used to query the corresponding screen parameters in the backup area when the screen mode...

Abstract
The invention belongs to the technical field of electronics, and particularly relates to a method and system for upgrading different display screens through the same software. The method includes operating upgrading software when equipment is started and reading values in an EEPROM (electrically erasable programmable readonly memory); determining starting situations of the equipment, changing the values when normal to allow the corresponding model number to be consistent with the model model of the equipment; when the starting situation is abnormal, changing the values forcibly and rewriting to the EEPROM to read; after the equipment is reset, determining the storing positions of interrupted screen parameters in a backup area according to the values and copying to an operation area; loading screen parameters, and allowing the equipment to display normally. By the aid of the method, the problems that when display equipment adopt same core, different types are produced according to display screens with different sizes, software with different types is needed to compile to configure display screen parameters, and accordingly development and production of products and big troubles are produced by maintenance after the products placed on the market are solved.
Description
technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a method and a system for upgrading different display screens by using the same set of software. Background technique [0002] In the current display devices, even if the display devices use the same core, they often need to be equipped with different types and sizes of display screens according to market demand, so that manufacturers need to develop various high-end, medium-end and low-end products. Since the hardware parameters of different types and sizes of displays are different, such as the size of the display, the resolution of the display, the timing of the display, the parity of the display, the brightness value of the display, etc., in many cases , the manufacturer does not need to make any modifications when replacing the same display screen of the product, but when changing different display screens of the product frequently, the manufacturer needs to ...
