Description
Technical field
The invention belongs to multimedia display terminal technology and digital television techniques field, relate to the method that realizes modular panel display.
Background technology
Along with the fast development in digital information epoch, progressively the widening and go deep into of computer system application scope, display device has become the requisite support equipments in field such as commerce and trade, Industry Control, armament systems.As flat-panel monitor have gently, approach, antivibration and energy-saving advantages, flat-panel monitor has great potential in each application scenario.
Because the flat-panel monitor Presentation Function is varied, the user who has needs display text, character form; The user who has only needs display digit information, as the radar data; The user who has needs display image such as telephotography, photo, map picture etc.And the flat-panel monitor screen size also is multifarious, so model is various; The flat-panel monitor that adopts non-modularization at present is that a kind of display of model is joined the circuit kit plate, and circuit board can not be general between each model, causes design complicated, and cost is too high, and the production maintenance is inconvenient.
Summary of the invention
The objective of the invention is to find out the general character of flat-panel monitor signal processing circuit, divide according to function and be designed to module.As the demonstration of the demonstration of digital video information, the demonstration of computer video signal, television video frequency signal, can select for use different display control modules to carry out multiple combination according to the Presentation Function of customer requirements.
Design proposal of the present invention comprises Comprehensive Control module (ICM), digital video load module (DVI), computer video load module (VGA), television video load module (TV), power conversion module (POWER), embedded detection module (BIT) and display panel module.
Concrete technical scheme of the present invention is as follows:
(1), Comprehensive Control module (ICM) (Integrate Control Module), be the central control unit of system, finish the control task of system, realize that the picture-in-picture (PIP) of multi-path digital baseband video signal shows.
(2), digital video load module (DVI) (Digital Video Input), the receiving high definition digital video signal, mainly be that digital video signal with TMDS (transmission minimized differential signal) or LVDS (low-voltage differential signal) or OpenLDI (open LVDS signal) interface converts the RGB parallel data stream to, give Comprehensive Control module (ICM) after treatment.
(3), computer video load module (VGA) (Video Graphics Adaptor), receive analog rgb HV vision signal, convert thereof into the RGB parallel data stream, give Comprehensive Control module (ICM) after signal is handled.
(4), television video load module (TV) (Television signal), receive and also to handle standard television signal (PAL, NTSC, SECAM) and/or digital rgb vision signal, can handle 2 tunnel video signal mixture.
(5), power conversion module (POWER) (Power Supply Module), input AC power frequency 220V power supply, 12V and 5V DC voltage that output system requires, the power supply of realization system.
(6), embedded detection module (BIT) (Built-in Test), the main devices of each signal processing module is monitored and is diagnosed, and carry out state by flat display module and show.
(7), display panel module can adopt liquid crystal (LCD) screen or the PDP screen more than 5 cun.
Display module not only should have relatively independent function, and has very high universalization, modularization, can accomplish to interconnect, and selects disparate modules, can be combined into the flat-panel monitor complete machine of different application function.
Display control module array mode such as table 1 have 12 kinds of integrated modes.Wherein ICM, POWER, BIT are basic module.
