Abstract
The utility model discloses a kind of Novel LCD drive plate, comprise power module, backlight drive module and liquid crystal driver module, described power module, backlight drive module and liquid crystal driver module are integrated to be located in same PCB, the mutual circuit of Jin Dao is adopted to connect between described power module, backlight drive module and liquid crystal driver module, described PCB is provided with liquid crystal screen backlight lamp bar interface, LVDS signal output interface and VGA signal input interface, and described PCB is fixed by screw.The utility model is designed to single pcb board assembly, and display complete machine assembling procedure is less, assembles more convenient, can obviously save human cost and Material Cost, decreases the quality risk that the loose contact that brought by electronic cable and connector brings simultaneously.
Description
Technical field
The utility model relates to a kind of lcd technology, particularly relates to the Novel LCD drive plate that a kind of integrated level is high, reliability is high.
Background technology
The drives part of liquid crystal display is the important component part of liquid crystal display, with reference to shown in accompanying drawing 1, the drives part of liquid crystal display forms primarily of three parts, namely power unit 10 ', backlight drive part 11 ' and liquid crystal drive part 12 ', every part is an independent PCB assembly.Power unit 10 is ' mainly for complete machine provides required stable working current and voltage, backlight drive part 11 ' is to provide constant drive current to the backlight module of liquid crystal display, liquid crystal drive part 12 ' is then for liquid crystal display provides the LVDS signal required for it (Low Voltage Differential Signal), thus guarantees that complete machine can meet and show needs normally.But the connection between this three partial circuit be all at present generally adopt original existing electronic cable 9 ' connected mode connect, this connected mode plate with need between plate 12 screws, 2 be connected electronic cable and 4 bus bar connectors, this Material Cost is higher; And need to assemble three secondary circuit board components respectively, lock 12 fixed screws and insert two winding displacements, so needing to use more human cost, cause human cost higher; Secondly, the circuit board of this separate type needs to drop into more manpower and materials when the assembling of complete machine finished product, and single component is more, and the difficulty of assembling is larger, and packaging efficiency is also on the low side, so both causes production cost too high; Moreover, electronic cable is adopted to carry out physical connection between plate and plate, long-time use, the hardware terminal of connector can be oxidized, if or user in use often move product, then may occur that winding displacement loosens, thus cause the hardware terminal loose contact of winding displacement and connector and produce quality hidden danger, meanwhile, owing to adopting electronic cable and row's seat physical connection, also can improve the fraction defective of product, this is unacceptable especially.
Utility model content
The purpose of this utility model provides for the deficiencies in the prior art the Novel LCD drive plate that a kind of integrated level is high, reliability is high, cost is low.
To achieve these goals, the technical scheme that the utility model provides is: provide a kind of Novel LCD drive plate, comprise power module, backlight drive module and liquid crystal driver module, described power module, backlight drive module and liquid crystal driver module is integrated is located in same PCB, described power module, the mutual circuit of Jin Dao is adopted to connect between backlight drive module and liquid crystal driver module, described PCB is provided with liquid crystal screen backlight lamp bar interface, LVDS signal output interface and VGA (DVI, HDMI) signal input interface, described PCB is fixed by screw.
Described power module has switch transformer and supply socket, for accessing power supply.
Described backlight drive module is connected by being located at the mutual circuit in PCB Shang Jin road with between power module, and described backlight drive module is provided with liquid crystal screen backlight lamp bar interface, provides constant drive current for accessing liquid crystal display to backlight module.
Described liquid crystal driver module is connected by being located at the mutual circuit in PCB Shang Jin road with between power module, and described liquid crystal driver module is provided with LVDS signal output interface, provides its Low Voltage Differential Signal for accessing liquid crystal display for liquid crystal display.
The beneficial effects of the utility model are, by PCBLAYOUT technology, liquid crystal to be shown that three partial circuit power modules of device, backlight drive module and liquid crystal driver module design are on same PCB by this Novel LCD drive plate, form a PCB assembly, become the three-in-one drive plate of a kind of Novel LCD, to realize the normal work of each several part circuit, the traditional connecting media between each circuit board can be saved completely: as connectors such as electronic cable, row's seats; And original three PCB assemblies become a present PCB assembly, originally needed when complete machine is assembled like this 2-3 PCB assembly is installed, and as long as a PCB assembly is installed now, the fixed screw of PCB assembly can be saved, more save assembling manpower and the production time of PCB assembly, enhance productivity, more avoid too much bus bar connector and cause the quality risk of loose contact.
Accompanying drawing explanation
Utilize accompanying drawing to be further detailed the utility model below, but the embodiment in accompanying drawing is not formed any restriction of the present utility model.
Fig. 1 is the schematic diagram of the conventional connected mode of LCD circuit plate group.
Fig. 2 is the structural representation of the three-in-one drive plate of the utility model embodiment Novel LCD.
Embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.
Shown in figure 2, the utility model embodiment provides a kind of Novel LCD drive plate, comprise power module 10, backlight drive module 11 and liquid crystal driver module 12, described power module 10, backlight drive module 11 and liquid crystal driver module 12 is integrated is located in same PCB 13, described power module 10, the mutual circuit of Jin Dao is adopted to connect between backlight drive module 11 and liquid crystal driver module 12, described PCB 13 is provided with liquid crystal screen backlight lamp bar interface 14, LVDS signal output interface 15 and VGA (DVI, HDMI) signal input interface 16, described PCB 13 is fixed by screw or fixing screens.
Described power module 10 has switch transformer 101 and supply socket 102, for accessing power supply.
Described backlight drive module 11 is connected by being located at the mutual circuit in PCB 13 Shang Jin road with between power module 10, described backlight drive module 11 is provided with liquid crystal screen backlight lamp bar interface 14, provides constant drive current for accessing liquid crystal display to backlight module.
Described liquid crystal driver module 12 is connected by being located at the mutual circuit in PCB 13 Shang Jin road with between power module 10, described liquid crystal driver module 12 is provided with LVDS signal output interface 15, provides its Low Voltage Differential Signal for accessing liquid crystal display for liquid crystal display.
For the utility model embodiment, designed on same PCB (printed wiring board) by three partial circuits of PCBLAYOUT technology by liquid crystal display, form single PCB assembly, and the connecting media of plate and plate becomes PCB Shang Jin road by original electronic cable, to realize the normal work of each several part circuit, this high composite design is compared compared with the circuit board group of the separate type connected conventionally by electronic cable, obviously succinct a lot, eliminate two and connect winding displacement, 4 bus bar connectors and 8 fixed screws, consume manpower during assembling also greatly to reduce, more avoid too much bus bar connector and cause the quality risk of loose contact.
