Existing TCON board management is cumbersome, and, the Source plate right side left to Source plate, TCON plate is needed to carry out independent ingress pipe
Reason, needs multiple system flows to be managed.Moreover, the material of existing TCON plate, packaging and transportation cost are higher, individually
Production is imported, board substrate and electronics material loss rate are high, expend working hour.More production capacity and transport space are occupied, and is packed
Three kinds of pallets are needed, three kinds of molds need to be opened, three kinds of test fixtures need to be made cost is caused to improve.Also, T-con plate and a left side
Source plate, right source plate are individually designed, need to design three pieces of circuit boards (timing master control borad, left plate, right panel) design week altogether
Phase lengthens, and when liquid crystal display assembles, production assembly technology increases client, increases production duration and manpower waste.In addition, three kinds of plates
It is individually designed that substrate is wasted when re-packing, and the pcb substrate proportion of goods damageds are high, meanwhile, need to make multiple test fixtures, Er Qiefen
At more plate pieces, surface mount elements are more, and when assembly, T-con plate and source plate need to use connecting material FFC (flexible flat electricity
Cable) connection, connecting material is wasted, high, low efficiency, labor intensive, material resources are required to technique in assembling process.Finally it is divided into more
More batches of shipment of plate need to occupy bigger transport space and manpower and material resources, waste packaging material, increase transportation cost, improve shipment
Risk.
Therefore, the utility model proposes a kind of using T-con plate and left source plate, three plate Integral type of right source plate
Design scheme makes liquid crystal display panel T-CON structure simpler and compact, with better function.Reduce piece in process of production
Number reduces and packs number by Source left plate, Source right panel and TCON plate, reduces the risk of multiple shipment, while
Reduce transportation cost.The utility model can effectively reduce the manufacturing cost of liquid crystal TV set, constantly promote company
The market competitiveness.

It needs to have connect T-con (logic) plate with left source plate, right source plate using flexible flat cable (FFC) plate in plate
Come, also needs to connect TV screen using flip chip (COF)；Because of flexible flat cable flip chip (COF) scrappage height, once
Property initial cost it is high, assembler misoperation easily causes the damage of flexible circuit；As described above, not only making process flow complicated
Change, and in assembling process, improve the scrappage of flexible flat cable (FFC) plate Yu flip chip (COF) plate, wastes people
Power material resources considerably increase product overall cost.
Fig. 2 is improved structure, by T-con plate and the three-in-one design of left source plate, right source plate in liquid crystal display
Layout, T-con and left and right source plate are merged into one piece of plate (XC-board).After the improvement of configuration aspects, nothing
Flexible flat cable (FFC) plate need to be used, while decreasing the use of flip chip (COF) plate quantity, keeps structure simpler
Single, assembling risk and production cost reduces.Process flow is simplified, makes TV liquid crystal panel structure simplerization, function more
Reinforce big.
