Description
Technical field
The present invention relates to a kind of repair wire structures, more particularly to a kind of repair wire structure of liquid crystal display panel.
Background technology
Liquid crystal display (Liquid crystal display, LCD) is current most widely used ground flat-panel monitor,
Have the characteristics that low-power consumption, slim body, light-weight and low driving voltage.In general, the display area of LCD is by multirow grid
Line (gate line) and multiple columns of data lines (date line) are interlaced forms, wherein arbitrary two adjacent grid lines and
A pixel region is formed between two adjacent data lines, thin film transistor (TFT) and pixel electricity are designed in each pixel region
Pole, the thin film transistor (TFT) serve as a switch module.
Data line is mainly used to provide vision signal with driving pixel electrode, as LCD panel resolution ratio is higher and higher, needs
The quantity for making data line is more and more, and the line width of data line becomes narrower, causes data line to be easy to break, breakpoint
Place's display is abnormal, and such case is known as line defect.In order to solve such situation, repair line can be generally set in panel,
Fig. 1 is the repair wire structure of the prior art, and repair line is generally divided into major trunk roads repair line 10 and Zhi Gandao repair lines 20, wherein propping up
Arterial highway repair line 20, which is between data line 30 and pixel region, to be used for connecting broken string, and major trunk roads repair line 10 is in outside data line 30
Zhi Gandao repair lines 20 are connected on driving chip (IC) 40.When data line breaks, by the data line and branch of broken string
Arterial highway repair line connection, then connects Zhi Gandao repair lines and major trunk roads repair line, such liquid crystal display is after molding process
The broken data wire that detected is bad to be repaired, and is reduced the fraction defective of product, is avoided larger waste, reduce life
Produce cost.But in process of production, due to the generation of electrostatic, Zhi Gandao repair lines are with major trunk roads repair line fusion point due to quiet
The place for not needing welding together, can be welding together, increase the impedance in repair line entire circuit, influence most by electricity and welding in this way
Whole repairing effect.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of repair wire structure of liquid crystal display panel, reduces electrostatic odds,
It ensures repair line repairing effect, avoids larger waste, reduce cost.
A kind of repair wire structure of liquid crystal display panel, liquid crystal display panel include crisscross several scan lines and data line, by sweeping
It retouches line and data line intersects the pixel region limited, it is characterised in that：The repair wire structure includes several arterial highway repair lines
With several major trunk roads repair lines, at least two are preset between each major trunk roads repair line and corresponding Zhi Gandao repair lines
Fusion point, when a certain or many places broken data wires, the data line of described Zhi Gandao repair lines one end and broken string connects, institute
The major trunk roads repair line stated is electrically connected with corresponding Zhi Gandao repair lines by least two fusion point.：It repairs
When, it is connected by the metal layer positioned at lower layer connects Zhi Gandao repair lines with major trunk roads repair line, the major trunk roads
The other end of repair line is connect with driving chip.The Zhi Gandao repair lines are described between data line and pixel region
Major trunk roads repair line is located at the outside of data line.The restorative procedure is laser repairing.
The present invention increases the quantity of fusion point by the design of Zhi Gandao repair lines and major trunk roads repair wire structure, reduces
Electrostatic odds ensures repair line repairing effect, avoids larger waste, reduce cost.
Description of the drawings
Fig. 1 show prior art repair wire structure schematic diagram；
Fig. 2 show repair wire structure of liquid crystal display panel schematic diagram of the present invention；
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
It the present invention rather than limits the scope of the invention, after having read the present invention, those skilled in the art are to of the invention each
The modification of kind equivalent form falls within the application range as defined in the appended claims.
As LCD panel resolution ratio is higher and higher, need the quantity for making data line more and more, the line width of data line becomes
Must be narrower, cause data line to be easy to break, display is abnormal at breakpoint, and such case is known as line defect.In order to solve
Such situation, can generally be arranged repair line in panel, and repair line is generally divided into major trunk roads repair line and Zhi Gandao repair lines.
The present invention provides a kind of repair wire structure of liquid crystal display panel, liquid crystal display panel include crisscross several scan lines and
Data line 30 intersects the pixel region limited by scan line and data line 30, as shown in Fig. 2, the repair wire structure includes several
Zhi Gandao repair lines 50 and several major trunk roads repair lines 60, the Zhi Gandao repair lines 50 be located at data line 30 and pixel region it
Between, the major trunk roads repair line 60 is located at the outside of data line 30, and in other embodiments, the Zhi Gandao of repair wire structure is repaiied
Multiple line and major trunk roads repair line are likely located at other positions, if Zhi Gandao repair lines are between data line and scan line, trunk
Road repair line is between pixel region.
When data line 30 breaks, using laser repairing by described 50 one end of Zhi Gandao repair lines with break
Data line 30 connect, 50 other end of Zhi Gandao repair lines is parallel with major trunk roads repair line 60, passes through the metal positioned at lower layer
Zhi Gandao repair lines 50 connect with major trunk roads repair line 60 and then are connected by layer 70, and junction is two or more fusion points 80,
The other end of the major trunk roads repair line 60 is connect with driving chip 40.
The present invention provides a kind of repair wire structure of liquid crystal display panel, passes through Zhi Gandao repair lines and major trunk roads repair wire structure
Design increases the quantity of fusion point, reduces electrostatic odds, in the case of having Electro-static Driven Comb, only can destroy one of them
Fusion point does not interfere with whole repairing effect, ensures repair line repairing effect, avoids larger waste, reduce cost.
