Signal mainboard upgrading device and method

Abstract

The invention provides a signal mainboard upgrading device and method, and belongs to the technical field of signal mainboards for display devices. The signal mainboard upgrading device and method can solve the problems that an existing signal mainboard upgrading mode consumes a long time and required equipment are complex. The signal mainboard upgrading device comprises a switching unit and a storage unit; the switching unit is used for being connected with a switching interface of a signal mainboard and controlling the working condition of the signal mainboard. The storage unit stores content used for upgrading the signal mainboard and is used for being connected with an information interface of the signal mainboard. The signal mainboard upgrading method comprises the steps that the switching unit is connected with the switching interface of the signal mainboard, the storage unit is connected with the information interface of the signal mainboard, the signal mainboard is set to be in a pause working condition through the switching unit; the content used for upgrading the signal mainboard and stored in the storage unit is written in the signal mainboard so that the signal mainboard can be upgraded. The signal mainboard upgrading device and method are particularly used for upgrading a Mstar V39 model signal mainboard.

Description

technical field [0001] The invention belongs to the technical field of signal main boards for display devices, and in particular relates to a signal main board upgrading device and method. Background technique [0002] Display devices such as televisions are equipped with a signal main board, which is used to convert video signals into a form recognizable by a display panel (such as a liquid crystal display panel), so as to drive and control the display process of the display panel. With the development of technology, it is necessary to frequently upgrade the driver software of the signal motherboard, so as to obtain better performance without replacing the hardware. [0003] According to the existing method, the upgrading process of the signal main board is relatively complicated. Take the upgrade of the MstarV39 signal motherboard (a signal motherboard used to drive the LCD panel) as an example, it needs to use a computer with a specific upgrade program installed, and the...
