Description
Technical field
The utility model relates to a kind of jigs more particularly to a kind of display panel residual charge to discharge jig.
Technical background
Liquid crystal panel flash problem is the great difficult problem not being fully solved always in industry, liquid crystal display panel it is big or middle,
There is the incidence of higher proportion in small each size model number, and along with higher unrepairable, seriously affects production yield
And efficiency.
When the principle of flashing is that liquid crystal display panel works, the polar voltages of driving liquid crystal molecule rotation are not right in positive and negative frame
Claim, it is different to cause to occur positive and negative polar light transmission rate, i.e., difference occurs in positive and negative frame brightness, and the two difference can by human eye
When discovering, macro manifestations are film flicker.
The reason of leading to panel flash, is varied, and wherein the residual charge in panel is affected to driving voltage,
If the residual charge in panel on each sub-pixel is different, when starting driving voltage is identical, it is actually added in each sub-pixel liquid crystal
The positive and negative frame voltage of molecule is different due to being influenced by residual charge polarity (relatively positive and negative property), and positive and negative frame is caused to occur
Luminance difference.
Meanwhile between each adjacent subpixels, it is driven the luminance difference of voltage difference and appearance, also shows as flashing.
The absolute value of residual charge numerical value is smaller in pixel, and the influence to practical driving voltage is also just smaller, therefore in order to
The hidden danger of residual charge is reduced, general panel factory selects the insulating materials of high impedance to prevent charge accumulated, even if even charge
There is accumulation, insulating materials unit area impedance can be reduced by heating or illumination using material property, charge is discharged.
Therefore, existing all multi-panel factories increase including high temperature processes in rear process links, effectively drop in production technology
The load value of the residual charge generated in low preceding process production process reaches the effective way for reducing flicker rate.
The mode of existing high-temperature process, which is generally used, to be directly heated panel, connects connecing for panel electrode using conductive material
Two ways is heated in the state of contact to color membrane substrates surface or ground terminal.
1) directly heat: panel directly heats, although can reduce residual charge, the release approach by charge is not proper and fast
Degree is slower, therefore reduces limitation, needs long-time high-temperature process or carries out heating for multiple times, causes damage to panel in this way
Possibility increases, and it is still undesirable to reduce degree.
2) conductive material heats, and electric conductor 4 is placed in array substrate 1 and color membrane substrates 2 as shown in Figure 1:, passes through conducting wire
5 access ground terminals 6, residual charge can be discharged into the external world by conducting wire 5 by electric conductor 4, can preferably reduce residual charge
Hidden danger.But in mass operation, there are the following problems, and causing panel itself, charge releasing degree is different everywhere for current factory
It causes, the probability of splashette is caused to be significantly increased instead:
A: since the step difference or even electric conductor 4 of array substrate 1 and color membrane substrates 2 deform, cause electric conductor 4 complete
Full connected is to electrode contact point 3；
B: what electric conductor 4 can not be fully effective touches all electrode contact points 3.
