Description
Technical field
The present invention relates to display technology field, change more particularly to resistance homogeneity between a kind of IPS display screens cabling
Kind method.
Background technology
TFT technology is to grow up nineteen nineties, using new material and the large-scale semiconductive of new process
Completely inegrated circuit manufacturing technology is liquid crystal（LC）, inorganic and organic thin film electroluminescent（EL and OEL）The base of flat-panel monitor
Plinth.Liquid crystal molecule in TFT display screens is transversely arranged, and liquid crystal molecule is overturn in space.IPS(In-Plane
Switching, plane conversion) compared with TFT display screens, pixel electrode is designed with public electrode in the same side display screen, is formed
Plane electric fields, liquid crystal molecule are overturn in face.Compared with TFT display screens, IPS display screens have that angle of visibility is big, color is true
It the advantages of real, dynamic image quality is remarkably, energy conservation and environmental protection and color are accurate, is widely applied in our life.
IC electric currents are connected by cabling and are input to AA areas in IPS display screens, in traditional design process, are connected to by AA areas
The cabling of Source IC, the cabling in both sides is longer, and intermediate cabling is shorter, causes the resistance value between cabling uneven, and electric
Resistance can influence the size in the electric current inflow AA areas of IC outputs, further influence the display effect of display screen, i.e., among display screen
Partial display effect is better than both sides.
The Z-shape arrangement of above-mentioned cabling is often made to solve the problems, such as away that line resistance is uneven in the prior art, but Z-type cabling accounts for
It is larger with space, influence the performance of IPS display screens.
The content of the invention
The defects of in order to make up prior art, the present invention provide a kind of improvement of resistance homogeneity between IPS display screens cabling
Method.
The technical problems to be solved by the invention are achieved by the following technical programs：
The ameliorative way of resistance homogeneity between a kind of IPS display screens cabling, the IPS display screens include several cablings, described
Cabling is used to connect AA areas and Source IC, which is characterized in that ITO blocks is set to form the resistance of series connection on the cabling, are led to
Overregulating the resistance of ITO blocks makes the resistance between each cabling uniform.
Further, the width of the ITO blocks is equal with the width of the cabling, by the length for controlling the ITO blocks
To adjust the resistance of ITO blocks.
Further, number is 1,2,3 ... m-1, m ... n to the cabling respectively from left to right, and when wherein n is odd number, m is
(n+3)/2；When n is even number, m is (n+2)/2；The resistance of each cabling is R1 ＞ R2 ＞ R3 ＞ ... ＞ Rm-1, Rm ＜ ... ＜ Rn；Respectively
The resistance of the ITO blocks set on cabling is L1 ＜ L2 ＜ L3 ＜ ... Lm-1, Lm ＞ ... ＞ Ln.
The present invention has the advantages that：
The present invention sets ITO blocks on cabling, by adjusting the resistance sizes of ITO blocks, the resistance of low resistance cabling is drawn high, is made
Resistance between each cabling is uniform, so as to control the uniform of the current value exported from IC, reaches the better purpose of display effect.
Description of the drawings
Fig. 1 is that ITO Kuai Hou AA areas are set in the present invention to the equivalent resistance schematic diagram of Source IC cablings.
Specific embodiment
With reference to embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention,
It is not limitation of the invention.
The ameliorative way of resistance homogeneity between a kind of IPS display screens cabling, the IPS display screens include several cablings,
The cabling sets ITO blocks to form the resistance of a series connection, passes through for connecting AA areas and Source IC on the cabling
Adjusting the resistance of ITO blocks makes the resistance between each cabling uniform.
Wherein, the width of the ITO blocks is equal with the width of the cabling, is adjusted by controlling the length of the ITO blocks
Save the resistance of ITO blocks.In the present invention, the thickness of ITO blocks is not particularly limited, this field just seems that personnel can be according to routine
The thickness of ITO blocks makes.
Specifically, refering to Fig. 1, number is 1,2,3 ... m-1, m ... n to the cabling respectively from left to right, and wherein n is odd number
When, m is (n+3)/2；When n is even number, m is (n+2)/2.In traditional design, both sides cabling is longer, and intermediate traces are shorter, causes
Resistance value between cabling is uneven, i.e., the resistance of each cabling is R1 ＞ R2 ＞ R3 ＞ ... ＞ Rm-1, Rm ＜ ... ＜ Rn；The present invention exists
ITO blocks are set on cabling, and the resistance of the ITO blocks set on each cabling is L1 ＜ L2 ＜ L3 ＜ ... Lm-1, Lm ＞ ... ＞ Ln.Respectively
The resistance of ITO blocks is considerably beyond the resistance of corresponding cabling on cabling, it is preferable that the resistance of ITO blocks is considerably beyond right on each cabling
Answer the resistance of cabling 100 times.The resistance of the small cabling of resistance is drawn high, made by adjusting the resistance sizes of ITO blocks by the present invention
Resistance between each cabling is uniform.
For example, 9 cablings are chosen, number is 1,2,3,4,5,6,7,8,9 to the cabling respectively from left to right, is measured
Its resistance R1 is 358.175 Ω, and R2 is 356.076 Ω, and R3 is 353.866 Ω, and R4 is 234.338 Ω, and R5 is 232.165 Ω,
R6 be 110.501 Ω, R7 be 112.636 Ω, R8 be 114.810 Ω, R9 be 229.973 Ω, i.e. R1 ＞ R2 ＞ R3 ＞ R4 ＞ R5,
R6 ＜ R7 ＜ R8 ＜ R9；ITO blocks are set on cabling, and the resistance of the ITO blocks set on each cabling is that L1 is 21.825 Ω, and L2 is
23.924 Ω, L3 are 26.134 Ω, and L4 is 145.662 Ω, and L5 is 147.835 Ω, and L6 is 269.499 Ω, L7 267.364
Ω, L8 are 265.19 Ω, and L9 is 150.027 Ω, i.e. L1 ＜ L2 ＜ L3 ＜ L4 ＜ L5, L6 ＞ L7 ＞ L8 ＞ L9, it is seen then that addition
After ITO blocks, the resistance between each cabling is uniform.
Embodiment described above only expresses embodiments of the present invention, and description is more specific and detailed, but can not
Therefore the limitation to the scope of the claims of the present invention is interpreted as, as long as the skill obtained using the form of equivalent substitution or equivalent transformation
Art scheme should all be fallen within the scope and spirit of the invention.
