Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to limit
The fixed present invention.
Embodiment 1
The present embodiment provides a kind of antistatic disabling device for display device, display device is used for display, display device
Including function cabling 1, it is located at the non-functional cabling 2 of 1 periphery of function cabling, such as Fig. 1, the antistatic disabling device includes extremely
Few one group of discharge tip combination, adjacent discharge tip combination settings gap.
In the present embodiment, when being influenced by exterior static, the tip of the discharge tip combination of outermost, meeting preferentially will be quiet
Position of the conductance flow direction far from functional cabling simultaneously discharges, and reduces the influence for functional cabling.Non-functional cabling 2 is most
Commonly GND lines can also be procedural test line, filling line（Block）Etc. a variety of cablings.
Specifically, the discharge tip combination includes at least one discharge tip 4, and discharge tip 4 is walked including nand function

The lead design of row different number.
The part discharged outside simple point is not limited to be designed in the form of uniform lines or in the form of special-shaped；When
Peripheral GND cablings or other non-functional cablings（Filling line, procedural test line or internal layer antistatic line etc.）1 it is adjacent when, can be with
It is carried out at the same time the two level protection form design inside and outside two layers of electrostatic tip.
Discharge tip combination is to need as conductor, for attracting or guiding charged object electrostatic charge in specified direction
Upper conduction and release.Therefore, the design about antistatic lead and tip in the present invention is to need exposed, electric discharge
Best results.But if when implementing the covering or protection of all or part of size to lead and tip using other materials, production
The anti-static effect of product will be declined, but still play the antistatic property of product certain effect.
In the present embodiment, for lead and the design protection of the outer portion at tip, for better defencive function cabling 1,
Different technique and insulating properties may be used to function cabling 1 or when semi-conducting material covers, can play preferably prevent it is quiet
Electrical property.
It is tested based on IEC61000-4-2 standards, general LCD products（Before fitting）Antistatic effect ± 6 ~ ±
8KV or so, OLED product（Before fitting）Antistatic effect in ± 2 ~ ± 4KV or so, TP products（Before fitting）Antistatic energy
Power is in ± 6 ~ ± 8KV or so；There are two reason is main：One is that device architecture determines, although one is had using simple
ESD is designed, but the effect actually played is not notable, causes the antistatic property of product bad.The present embodiment can be by OLED
The atmospherical discharges antistatic property of product is increased to ± 8KV or more, and the atmospherical discharges antistatic property of LCD is increased to ± 15KV
More than, the atmospherical discharges antistatic property of TP is increased to ± 12KV or more.
