Abstract
The invention provides a long wire driving based ultra-thin multi-screen splicing display system, which comprises a signal source, a cabinet type splicing control system, a long wire driving module, a splicing screen display module and a splicing wall. The long wire driving based ultra-thin multi-screen splicing display system has the following technical effects: 1) the independent setting of the cabinet type driving module enables the multi-screen splicing wall to realize ultra-thin splicing technology; 2) the special LVDS long wire driving module is adopted, thereby being capable of increasing the signal transmission distance between the driving module and a display screen according to requirements. However, attenuation of signals does not occur under the condition of increasing the signal transmission distance, thereby avoiding the problems that driving signals can not be transmitted for a long distance in a traditional mode, and that the signals are attenuated because of lengthening of the transmission distance.
Description
Technical field
Of the present inventionly provide a kind of ultrathin multi-screen splicing display system and display packing thereof that drives based on long line, belonged to screen splicing display technique field.
Background technology
Along with the development of multi-screen splicing display technique, multi-screen splicing wall has obtained increasing favor with its high definition, color effect true to nature, big picture at present; The high resolving power of splicing large screen can be passed on more information, can satisfy many-sided demands such as real-time monitoring, command scheduling, report displaying, advertising, has obtained large-area universal use; And some is to allow it show the key point of perfect picture in this whole multi-screen connected welding system, is to come that by this part picture signal is carried out data to handle, and changes out required image effect and color; This part is exactly drive control part so.
In design in the past, driver module partly is the back side that directly is placed in display panel, because screen itself has certain thickness to add the thickness of driver module, has increased the thickness of combination undoubtedly, makes then will occupy very big space between combination and the metope; And in actual use, people tend to because saving the space video wall is close to metope, so will bring very big inconvenience to maintenance; And driver module is placed in the display panel back can brings a problem: display panel can produce certain heat because of luminous when the start operation, the same control enclosure that drives can give out heat too when work, though the design of fan is arranged, but fan can bear very big pressure, in case fan has been broken, can't dispel the heat in the whole front panel back shroud so, undoubtedly to certain danger is arranged in serviceable life of equipment; Most importantly driver module is built-in, so the transmission signal distance is very short.Just not saying can't lengthen signal wire, even lengthened signal wire, effect also allows of no optimist; Code book can be along with the decay of distance signal more far away be more serious in remote transmission, and traditional LVDS line has no idea to remove the phenomenon of the signal attenuation of this process at all; Though some combination can drive screen at a distance, all can't support the display frame of high definition mostly.
