Modular TV and screen end upgrade method thereof

Abstract

The present invention discloses a modular TV screen end upgrade method. The method comprises the steps that a screen end sends an upgrade request to a card end when an upgrade instruction is detected; the card end obtains the configuration file in external equipment according to the upgrade request and sends the configuration file to the screen end; the screen end obtains the configuration file and the matched upgrade request information in the upgrade instruction, and sends a file acquisition request to the card end according to the upgrade request information; the card end obtains the system file in the external equipment according to the file acquisition request and sends the system file to the screen end; and the screen end carried out upgrading according to the system file. The invention also discloses a modular TV. In the condition that the screen end can not use an hardware external interface directly, a traditional TV force upgrade method is applied to the screen end upgrade of the modular TV, the upgrade operation of the modular TV screen end is simplified, thus the system recovery efficiency after the failure of a product in a production line is improved, after-sale service operations are simplified, and the production cost can be reduced too.

Description

technical field [0001] The invention relates to the technical field of upgrading electronic products, in particular to a modular TV and a screen end upgrading method thereof. Background technique [0002] The traditional TV forced upgrade method is to copy the system files to an external device, such as a U disk, and insert the U disk into the TV when the system has crashed (that is, the product is faulty) and only the boot (guide) program is valid. Finally, press and hold the power button (power button) of the TV to put the TV into standby mode, press the default upgrade trigger button (such as the volume adjustment "+" button) to restart the TV and enter the boot mode, and then insert the U disk Burn the system files in the TV to the flash (flash memory) of the TV, so that the system can run again. The above-mentioned forced TV upgrade method is widely used in manual system recovery after product failure on the production line, and product after-sales service. [0003] T...

AI Technical Summary

Problems solved by technology

However, the upgrade operation of the above-mentioned forced upgrade method on the screen end is complicated, resulting in a serious low system recovery efficiency after a product failure on the production line, which increases production costs; moreover, the above-mentioned upgrade method requires the operator to use the forced upgrade software on the PC end, which increases the The technical requirements for operators on the production line, and each production station must be equipped with a PC, resulting in a further increase in production costs
