Description
Technical field
The utility model relates to television technologies, particularly the compatible technology of panel TV set mainboard and display screen.
Background technology
Development along with television industries; Panel TV set has become the main flow of consumption; Because client to the diversity of the demand of panel TV set, makes the size of panel TV set cover plurality of specifications such as 19 cun to 58 cun, display screen is the important composition parts of panel TV set; And the used display screen of each television set manufacturer has all comprised the display screen of tens kinds of specifications and models of other different manufacturers; Be not quite similar because the input signal of display screen is the form of LVDS (Low-Voltage Differential Signaling, Low Voltage Differential Signal) signal, the display screen of different manufacturers, different model often can not be general; It is the display screen that a kind of panel TV set mainboard of model often can only use several kinds of a kind of or limited models; If in the research and development of products process, need to change the display screen of different manufacturers, then in a single day can not be general, the times of incuring loss through delay for two weeks are at least set type again, assemble mainboard; Directly influence research and development, the testing progress of product, and the problem that display screen can not be general has equally also been brought great inconvenience to the product maintenance stage.According to one's analysis, panel TV display screen input signal generally is made up of several groups of LVDS differential signals, and right ordering often is not quite similar to cause the different general reasons of display screen of different manufacturers to be the LVDS differential signal.
The utility model content
The purpose of the utility model is to overcome the shortcoming that present panel TV set mainboard can only use the display screen of several kinds of a kind of or limited models, and a kind of panel TV set display screen compatible apparatus is provided.
The utility model solves its technical problem; The technical scheme that adopts is; Panel TV set display screen compatible apparatus is characterized in that, comprises signal input part, signal output part and switching controls module; Said signal input part is connected with the switching controls module, and signal output part is connected with the switching controls module.
Concrete, said switching controls module adopts FPGA (Field-Programmable Gate Array, field programmable gate array) chip.
Further, also comprise power module, said power module is connected with the switching controls module.
Concrete, said signal input part is the LVDS signal input part, said signal output part is the LVDS signal output part.
The beneficial effect of the utility model is; Signal input part is connected with the panel TV set mainboard; Signal output part is connected with the display screen that needs coupling; Being the panel TV set mainboard is connected with display screen through above-mentioned panel TV set display screen compatible apparatus, and according to the format configuration switching controls module of the incoming video signal of the display screen reception of the form of panel TV set mainboard outputting video signal and needs coupling, the vision signal of the panel TV set mainboard being exported by the switching controls module converts the employed incoming video signal of this display screen into; Realize the compatibility of panel TV set mainboard and this display screen; Through changing the switching controls modules configured, then can make the display screen that this panel TV set mainboard can compatible specifications and models that only maybe be many, do not need to carry out again the composing again of mainboard etc.; Shorten the R&D cycle, and offer convenience for the later maintenance stage.
Description of drawings
Fig. 1 is the system block diagram of embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment, describe the technical scheme of the utility model in detail.
The said panel TV set display screen of the utility model compatible apparatus is connected with the switching controls module by signal input part; Signal output part is connected with the switching controls module; Power module and switching controls module connect to form; Signal input part is connected with the panel TV set mainboard; Signal output part is connected with the display screen that needs coupling, and promptly the panel TV set mainboard is connected with display screen through above-mentioned panel TV set display screen compatible apparatus, the format configuration switching controls module of the incoming video signal of the display screen reception of mating according to the form and the needs of panel TV set mainboard outputting video signal; The vision signal of the panel TV set mainboard being exported by the switching controls module converts the employed incoming video signal of this display screen into, realizes the compatibility of panel TV set mainboard and this display screen.
Embodiment
This routine panel TV set display screen compatible apparatus also has power module, its system block diagram such as Fig. 1.
At first be connected with the switching controls module by signal input part; Signal output part is connected with the switching controls module; Power module and switching controls module connect to form this routine said panel TV set display screen compatible apparatus, and wherein, signal input part is the LVDS signal input part; Signal output part is the LVDS signal output part, and the switching controls module is made up of fpga chip and peripheral circuit thereof.
Through analyzing; The implementation that the LVDS of panel TV goes up screen signal (vision signal) for (is example with 10bit) according to certain sequence with digital signal (R0～R9; G0～G9, B0～B9, DEN, Hsync, Vsync) arrange, transmit through several groups of differential signals; On the display screen of different size the screen signal in numeric sorting all be identical, difference is the ordering of physical interface and differential signal.Then signal input part is connected with the panel TV set mainboard; Signal output part is connected with the display screen that needs coupling; Be that the panel TV set mainboard is connected with display screen through above-mentioned panel TV set display screen compatible apparatus; And the format configuration switching controls module of the incoming video signal that receives according to the display screen of the form of panel TV set mainboard outputting video signal and needs coupling; The vision signal of the panel TV set mainboard being exported by the switching controls module converts the employed incoming video signal of this display screen into; As being that the input signal of LVDS0, LVDS1, LVDS2, LVDS3, LVDS4 switches to the output signal that sortord is LVDS4, LVDS0, LVDS1, LVDS2, LVDS3 with sortord through hardware programming; Realize the compatibility of panel TV set mainboard and this display screen, again through changing the switching controls modules configured, then can make this panel TV set mainboard can be compatible only maybe specifications and models how display screen.Wherein, power module is used for supplying power to the switching controls module, and when not having power module, can be supplied power to the switching controls module through signal input part by mainboard.
Because each the module physical circuit in the utility model technical scheme belongs to prior art, no longer detail here.Those of ordinary skill in the art according to foregoing description, can adopt various physical circuits to realize the technical scheme of the utility model, and it all belongs to the protection range of the utility model.
