The invention greatly reduces the cost for manufacturing an LCD monitor.
Description
Technical field
The present invention relates to the monitor field, particularly a kind of LCD monitor.
Background technology
The broadcasting that has existed at present generally all is to use professional monitor pattern process module with monitor, and (professional purpose is different from the computer LCD owing to monitor.LCD monitor generally all needs to provide multi-information source to show especially SDI (serial data interface) of multiple interfaces, the computer LCD generally all is that computer display interfaces such as VGA, DVI only are provided) market plane is narrow, application quantity is less with respect to TV, so be difficult on the cost have superiority.General monitor lcd applicator platform all is that professional pattern process module is unaided, but professional pattern process module costs an arm and a leg, in price and the technical advantage that does not all have the LCD TV pattern process module.
Summary of the invention
The present invention overcomes the shortcoming of prior art, and a kind of LCD monitor is provided, and the present invention uses the ripe platform of LCD TV and the advantage of cost aspect effectively, makes the cost of LCD monitor significantly reduce.
In order to solve the technical problem of above-mentioned existence, the present invention is achieved through the following technical solutions: a kind of LCD monitor, comprise the serial data interface module that is used to export serial data signal that is electrically connected successively, being used for serial data signal unstringed becomes the serial data of the parallel ITU-R.BT.601 picture intelligence module of unstringing, and is used for will parallel ITU-R.BT.601 picture signal handling and being transferred to LVDS signal format the pattern process module of liquid crystal display screen reception.
In LCD monitor of the present invention, also comprise the balance module of the transmission loss that is used to compensate serial data signal, be used for signal that serial data signal carries out waveform shaping reshaper synchronously again; Described serial data interface module output signal end successively by balance module, signal more synchronously unstring module, image processing module of reshaper, serial data be connected with the input of liquid crystal display screen.
In LCD monitor of the present invention, also comprise the cable drive module, the output signal end of described serial data interface module also is connected with the input of next monitor by balance module, cable drive module.
In LCD monitor of the present invention, also comprise single-chip microcomputer, infrared remote-control device, key control device, EEPROM (Electrically Erasable Programmable Read Only Memo), described infrared remote-control device, key control device, EEPROM (Electrically Erasable Programmable Read Only Memo) are electrically connected with image processing module by single-chip microcomputer respectively.
In LCD monitor of the present invention, described balance module is the LMH0034 balance module; The synchronous again reshaper of described signal is the synchronous again reshaper of LMH0046 signal; The described serial data module of unstringing is the LMH0031 serial data module of unstringing; Described image processing module is the LX66 image processing module.
In LCD monitor of the present invention, described pattern process module is the pattern process module that is used for TV.
The present invention compared with prior art has following advantage and beneficial effect: the TV graphical processing module that wood invention has been used is as the processing of parallel signal, use the serial data of the specialty module of unstringing, serial data unstringed is the ITU-R.BT.601 signal, by the TV graphical processing module as post-processed.So only need on original LCD TV platform, make modification slightly, remove intermediate frequency amplifier circuit, the first-class TV device of high frequency, keep pattern process module and power supply, control circuit etc., increase necessary serial data unstring module, serial data equilibrium and cable actuated module, original TV platform can be applied to greatly reduce the LCD monitor manufacturing cost on the LCD monitor.
Description of drawings
Fig. 1 is the structural representation of a kind of LCD monitor of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with embodiment and accompanying drawing, but embodiments of the present invention are not limited thereto.
Embodiment
As shown in Figure 1, a kind of LCD monitor, comprise the serial data interface module that is used to export serial data signal that is electrically connected successively, being used for serial data signal unstringed becomes the serial data of the parallel ITU-R.BT.601 picture intelligence module of unstringing, and is used for will parallel ITU-R.BT.601 picture signal handling and being transferred to LVDS signal format the pattern process module (this pattern process module is the pattern process module that is used for TV) of liquid crystal display screen reception;
Monitor of the present invention also comprises: be used to compensate the balance module of the transmission loss of serial data signal, be used for signal that serial data signal carries out waveform shaping reshaper (can utilize LMH0046 signal again reshaper) synchronously synchronously again; Described serial data interface module output signal end successively by balance module, signal more synchronously unstring module, image processing module of reshaper, serial data be connected with the input of liquid crystal display screen, the output signal end of described serial data interface module also is connected (if do not need serial data is exported to the next stage monitor, then can save the cable actuated module) by balance module, cable drive module with the input of next monitor.
This LCD monitor also comprises DDRRAM, single-chip microcomputer, infrared remote-control device, key control device, EEPROM (Electrically Erasable Programmable Read Only Memo), and described infrared remote-control device, key control device, EEPROM (Electrically Erasable Programmable Read Only Memo) are electrically connected with image processing module by single-chip microcomputer respectively.Described DDRRAM is electrically connected with image processing module.
Above-mentioned balance module is the LMH0034 balance module; Described signal is the synchronous again reshaper of the LMH0046 of reshaper employing synchronously signal again; The described serial data module of unstringing adopts the LMH0031 serial data module of unstringing; Described image processing module adopts the LX66 image processing module; The cable drive module then adopts the LMH002 driver module.
The present invention will integrate in the pattern process module and the serial data interface module (SDI) of TV maturation, serial data (sdi signal) is unstringed by the serial data interface module, output ITU-R.BT.601 signal is exported LVDS signal to liquid crystal display screen again and is shown to the simulated television pattern process module.
Above integration mode and simple monitor scheme are compared, the cheap technology maturation of pattern process module departmental cost, and exploitation is simple.By using the vehicular transmission of ITU-R.BT.601 signal, make two to seem the module that has no to concern and to be applied to a monitor integral body.The TV graphical processing module is used on TV platform on a large scale, and is with low cost, makes whole the comparing with the monitor of simple use monitor pattern process module on cost of this monitor that very big advantage be arranged.
