Description

A kind of modularization TV

Technical field

The present invention relates to television set more particularly to a kind of modularization TVs.

Background technique

With the development of large scale integrated circuit, television set also adds the structural development of discrete device to extensive from single-chip microcontroller The structure of integrated IC, integrated level are also higher and higher.As the CPU of 2 cores, 4 cores, 8 cores integrates the TV processing chip of multiple GPU It constantly releases, the processing IC function of television set is more and more stronger, and a substantially processing IC is capable of the phase of Management Television machine at present It should apply and the driving of peripheral equipment.TV processing IC building circuit structure be located in TV motherboard, be responsible for driving, dispatch, The all devices peripheral hardware on Management Television machine periphery.However, the needs of different peripheral upgrading are not for television set peripheral hardware Together, the upgrading of some peripheral hardwares is very fast, some peripheral hardwares even not will do it upgrading in the life cycle of television set, whole For be that comparison is slow.

With the fast development that the processing IC of television set makes rapid progress with Internet technology, the need of Internet application upgrading The peripheral hardware upgrading speed that will lead to television set is asked to accelerate.However, the mainboard of television set and its related structure in the prior art At circuit framework be fixed in TV motherboard, Fig. 1 shows prior art TV motherboard and its periphery input-output equipment Theory structure block diagram, TV processing IC is provided in TV motherboard 1 ' and its periphery processing circuit, periphery are connected with power panel 2 ' be that TV motherboard 1 ' provides power supply, backlight drive board 3 ' for the backlight that image needs provides driving and external equipment 4 ', TV Mainboard 1 ' is provided with input interface RJ45, USB, HDMI, CVBS, Ypbpr, and 1 ' output timing signal of TV motherboard is to being connected thereto TCON plate 5 ', then be output to the display screen 6 ' connecting with TCON plate 5 ' and shown.The upgrading that this structure carries out TV is changed In generation, needs replacing TV motherboard, and newly-increased peripheral hardware can not be just adapted to by being changed without TV motherboard, so that television set is long at it In life cycle, function is unable to satisfy the demand of user soon.For R&D work, upgrading means about aobvious The related research and development show, driven need accordingly to be upgraded according to TV applications and television set processing IC, based on current circuit frame Structure, all R&D work needs re-start, and the work for manufacturing link is also required to re-start, therefore causes many Unnecessary waste.Also, for a user, because portion of external equipment carries out TV motherboard, upgrading is also inconvenient, Exploitation upgrading can not be customized.

Therefore, the existing technology has yet to be improved and developed.

Summary of the invention

Place in view of above-mentioned deficiencies of the prior art, the present invention are to solve the defect and deficiency of the prior art, propose one kind IC only can be handled to TV and its peripheral circuit carries out function upgrading, do not needed to tv display screen and periphery processing circuit The modularization TV of upgrading.

The present invention provides a kind of modularization TV for facilitating upgrading, and it is as follows to solve technical solution：

A kind of modularization TV, including TV motherboard and the backlight drive module being electrically connected with the TV motherboard, power supply mould Peripheral hardware and display screen on block, screen, the TV motherboard are separated into the function application module and screen end drive module of communication connection；Institute State the sound of function application module reception TV, vision signal carries out processing and is sent to screen end drive module, the screen end drive Dynamic model block receive capabilities application module treated audio signal, vision signal, and be respectively outputted to shield peripheral hardware to export sound Frequently, display screen is output to show video.

Compared with prior art, the present invention, which takes, handles IC and its periphery processing circuit and screen end for prior art TV Peripheral circuit is discrete comes for driving, is attached communication by the data-interface of standard and audio, video data transmits, TV processing IC and periphery processing circuit stand alone as function application module, receive the audio-video signal of processing input TV and carry out TV applications Processing, screen end driving peripheral circuit then only processing display data and voice data realize data capability processing of less demanding Function, screen end driving peripheral circuit stand alone as screen end drive module, carry out the control of display video correlation timing, sound effect control The drive control for the peripheral hardware that system, backlight logic control and TV periphery need to use.By the big TV IC of calculation process amount and fortune Calculating the small screen end part separate design for the treatment of capacity isolates display, driving function in original TV motherboard from TV motherboard Come, functional application part can carry out TV host CPU and its individually designed and upgrading of IC according to the needs of users, shield end in electricity Life cycle depending on machine substantially can be without replacement, and display driver circuit is without re-starting exploitation design, great function Upgrading only needs to update function application module, facilitates the upgrading of TV, reduces the cost of upgrading.
