Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
The embodiment of the present invention provides a kind of color membrane substrates, as it is shown in figure 1, include underlay substrate 10 and black matrix 20, also includes the first antistatic backing 30 being arranged on the side of black matrix 20 away from substrate substrate 10, and the first antistatic backing 30 contacts with black matrix 20；First antistatic backing 30 ground connection.Wherein, the resistivity of the first antistatic backing 30 is less than the resistivity of black matrix 20.
It should be noted that the first antistatic backing 30 is the resistivity conductive material less than the resistivity of black matrix 20, the electric charge importing in black matrix 20 and storing can be made preferentially to be derived to earth terminal (GND) by the first antistatic backing 30.On this basis, little more many of the resistivity of the resistivity ratio black matrix 20 of the first antistatic backing 30, then the speed that electrostatic is derived by the first antistatic backing 30 is more fast, and influence time and influence degree to the liquid crystal display of color membrane substrates are more little.Preferably, the material of the first antistatic backing 30 is Graphene.
Owing to the resistivity of Graphene only has 10-6Ω cm, it has perfect two dimensional crystal structure, its lattice is the hexagon surrounded by six carbon atom, and thickness is an atomic layer, in Graphene, each carbon atom has the P electronics of a non-Cheng Jian, these P electronics can move freely in lattice, and movement velocity can reach the 1/300 of the light velocity so that Graphene has good electric conductivity, under room temperature state, the electron mobility of Graphene is more than 15000cm2/V·s.Use Graphene as the material of the first antistatic backing 30, substantially increase the electrostatic in black matrix 20 and preferentially derived the conduction velocity to earth terminal (GND) and derivation effect by the first antistatic backing 30.
The electrostatic of above-mentioned color membrane substrates inner accumulation is derived to earth terminal (GND) by the first antistatic backing 30, wherein, above-mentioned earth terminal (GND) can be separately provided, or preferred with array base palte on to be positioned at the earth terminal (GND) driving binding region shared, concrete, after color membrane substrates and array base palte vacuum are to box, the first antistatic backing 30 is connected with driving the earth terminal (GND) bound in region on array base palte.
In this situation, above-mentioned first antistatic backing 30 can be connected with the earth terminal (GND) on array base palte by the conductive silver glue 03 that pass through as shown in Figure 2.Due to conductive silver glue 03 good conductivity, and be colloidal state, after point is applied on substrate, not easily bleed around, and connectivity is good, therefore can pass through conductive silver glue 03 to be connected with the earth terminal (GND) in wiring area on array base palte by first antistatic backing 30, so that the electrostatic of color membrane substrates inner accumulation is derived by conductive silver glue 03 by the first antistatic backing 30.
The color membrane substrates that the embodiment of the present invention provides, in the side of black matrix away from substrate substrate, the first antistatic backing is set, first antistatic backing contacts with black matrix, make the black matrix can with the first antistatic backing UNICOM, the resistivity of the first antistatic backing is less than the resistivity of black matrix, the electrostatic imported and accumulate in black matrix can preferentially conduct to the first antistatic backing, first antistatic backing ground connection, the electrostatic importing the first antistatic backing is derived to earth terminal (GND), on the one hand, in use, produce and import the electric charge within color membrane substrates to be derived to earth terminal (GND) by the electrostatic of the first antistatic backing, avoid buildup of static electricity to form electric field and cause that pixel periphery is shinny, produce display abnormal；On the other hand, when the antistatic effect test that liquid crystal panel dispatches from the factory, the big voltage of instantaneous access can quickly be exported, it is to avoid electric charge punctures the circuit on array base palte, causes the damage of liquid crystal panel.
As in figure 2 it is shown, color membrane substrates is divided into viewing area A and is arranged at the non-display area B of viewing area A periphery, the first antistatic backing 30 contacts with black matrix 20 it may be that the first antistatic backing 30 contacts with black matrix 20 at non-display area B；Or the first antistatic backing 30 contacts with black matrix 20 at viewing area A, as long as ensureing that the first antistatic backing 30 contacts with black matrix 20, it is possible to realize the conducting of electric charge.Preferably, the first antistatic backing 30 is arranged in non-display area B.So, the electrostatic of accumulation in black matrix 20 is conducted and derives to while earth terminal (GND) ensure that, it is thus also avoided that the first antistatic backing 30 being positioned at viewing area A is likely to the impact that the display effect on viewing area A produces.
When the first antistatic backing 30 is arranged at non-display area B, it is possible to as in figure 2 it is shown, arrange around viewing area A, and end to end, the optional position spot printing conductive silver glue 03 at the first antistatic backing 30 is connected with earth terminal (GND).
Or, as shown in Figure 3, first antistatic backing 30 is arranged in non-display area B, can also be that strip is arranged around viewing area A, when using the first antistatic backing 30 of multiple strips, owing to not connecting mutually between the first antistatic backing 30 of multiple strips, then the first antistatic backing 30 of each strip needs spot printing conductive silver glue 03 to be respectively connected with above-mentioned earth terminal (GND), and use the first antistatic backing 30 around the end to end setting of viewing area A only to need the electric charge that optional position on the first antistatic backing 30 can be imported by spot printing primary conductive elargol 03 at an arbitrary position to be derived by earth terminal (GND), what save earth terminal (GND) arranges quantity.
On this basis, when the first antistatic backing 30 is arranged at non-display area B, the width W1 that the first antistatic backing 30 is arranged ranges for 1～100 μm.
The width W1 of the first antistatic backing 30 is arranged in 1～100 μ m, if the width W1 of the first antistatic backing 30 is less than 1 μm, then it is likely to be due to the narrow increase technology difficulty of width W1, and the first antistatic backing 30 of coating is susceptible to braking effect electrostatic and derives effect, if the width W1 of the first antistatic backing 30 is more than 100 μm, wastes material cost and be unfavorable for the narrow frame design of color membrane substrates.
Further, the thickness h 1 of the first antistatic backing 30 is 1.0～6.0 μm.
The thickness h 1 of the first antistatic backing 30 is arranged in 1.0～6.0 μ m, if the thickness h 1 of the first antistatic backing 30 is less than 1.0 μm, then it is likely to be due to the too small increase technology difficulty of thickness h 1, and the first antistatic backing 30 of coating is susceptible to braking effect electrostatic and derives effect, if the thickness h 1 of the first antistatic backing 30 is more than 6.0 μm, the integral thickness of waste material cost and increase color membrane substrates.
Additionally, the width W2 of sealed plastic box 40 is usually arranged as in 400～700 μ m, the first antistatic backing 30 can be arranged with sealed plastic box 40 W3 separated by a distance, it is also possible to setting overlapping with sealed plastic box 40.
Below when the width W1 of the first antistatic backing 30 and thickness h 1 lay respectively in above-mentioned preferable range, the concrete set-up mode for being arranged in first antistatic backing 30 of non-display area B carries out detailed illustration.
