Description
Technical field
The present invention relates to all-in-one machine technical field of video signal, more particularly to a kind of raising all-in-one machine vision signal resists
The circuit module of interference performance.
Background technology
Computer all-in-one machine is the novel market product of one between current desktop computer and laptop, it is by host portion
Divide, the neomorph computer that display part is integrated together, the innovation of the product is the highly integrated of internal element.With nothing
The development of line technology, keyboard, mouse and the display of computer all-in-one machine can realize wireless link, and machine only has a power cord.
Which solves more than the desktop computer cable that denounces of behaving always and it is miscellaneous the problem of.In existing and following market, with desktop computer
Share gradually decrease, then encounter be certain to after the impact of all-in-one machine and notebook and net book it is more precarious.And one
The advantage of machine is constantly accepted（It is external popular）Another bright spot selected as them.
As computer minimizes, the development of lighting, all-in-one machine computer equipment is flourished, some manufacturers will
All-in-one machine computer is done even also smaller than laptop, gos deep into the welcome of consumers in general.But the mainboard of all-in-one machine and
The electric power system of peripheral hardware is that together, the electrical High-frequency Interference of mainboard is easy to be added to peripheral system, causes all-in-one machine
The undesirable problematic phenomenon such as display picture water ripples, ghost image.
Invention content
In order to solve problem of the prior art, the present invention provides a kind of raising all-in-one machine vision signal antijamming capabilities
Circuit module increases power isolation circuit between integration machine mainboard and video driving module, improves video driving module
Power supply antijamming capability；In addition, the VGA vision signals that mainboard is exported are designed by signal isolation, the anti-of vision signal is improved
Interference performance.
The technical solution adopted in the present invention is as follows：
A kind of circuit module for improving all-in-one machine vision signal antijamming capability, including all-in-one machine power module, the one
Electromechanical source module is integrally connected machine video driving module, integration machine mainboard and all-in-one machine liquid crystal display, all-in-one machine video respectively
Drive module includes power isolation circuit and VGA signal isolation circuits, and the one is reached in the all-in-one machine power module
The power supply signal of machine video driving module is connected to power supply circuit by power isolation circuit first, while by the power supply after isolation
Signal is sent to all-in-one machine liquid crystal display, and the VGA vision signals that the integration machine mainboard is sent out are input to the drive of all-in-one machine video
The VGA signal isolation circuits of dynamic model block are then converted to LVDS signals and are sent to the all-in-one machine liquid crystal display.
Power isolation circuit selects independent isolated power supply module or isolated power supply chip is carried out circuit design.
VGA vision signals are analog signal, and isolation design is carried out by the way of coupled capacitor is concatenated.
The advantageous effect that technical solution provided by the invention is brought is：
A kind of circuit module of raising all-in-one machine vision signal antijamming capability of the present invention, is the electricity by video driving module
The isolation design of source and incoming video signal is realized.Increase isolation electricity between the mainboard module of all-in-one machine and video driving module
Source module improves the power supply antijamming capability of video driving module.The VGA vision signals of the mainboard module output of all-in-one machine carry out
Isolation processing improves the antijamming capability of vision signal.
