Abstract
The utility model discloses a liquid crystal display for preventing rainbow due to clipping of PIN. A liquid crystal display panel (1) comprises upper conducting glass (1a) and lower conducting glass (1c) which are bonded into a sealing box by a frame sealant (1d), a liquid crystal layer (1b) is arranged in the sealing box, an ITO electrode layer of the lower conducting glass (1c) and one side of the lower conducting glass (1c) extend to the outside of the sealing box to form a connection part, insulated flexible glue (4) is sealed in a crack between the upper conducting glass (1a) and the lower conducting glass (1c) and close to one side of the connection part outside the sealing box, the head of a metal PIN needle (2) is clipped on the connection part spotted with conducting carbon ink (3), and the metal PIN needle (2) and the connection part are solidified together by UV glue or AB glue (5). Before the UV glue or the AB glue solidifies, the sealing process of the insulated flexible glue is increased, the UV glue or the AB glue can be effectively prevented from permeating into the crack between the upper conducting glass and the lower conducting glass, and the bad rainbow caused by hard glue generated after solidifying is avoided.
Description
Technical field
The utility model relates to liquid crystal display device structure, relates in particular to the liquid crystal display that rainbow appears in a kind of pre-anti-pinch PIN.
Background technology
Liquid crystal display, compared with regular display, has lot of advantages: (1) volume is little, lightweight;
(2) low in energy consumption, the life-span is long; (3) not containing harm ray; (4) passive demonstration, is difficult for being washed away by high light; (5) be easy to drive, available large scale integrated circuit directly drives; (6) simple in structure, there is no a complicated mechanical part; (7) cost is low etc.
At present, between LCD display panel and part peripheral components, can be connected by the most stable PIN pin of conduction, concrete connected mode is: PIN pin is directly connected on the electrode pin of liquid crystal panel, adopts UV adhesive sealing and reached and solidified object or adopt AB glue spontaneous curing sealing by UV illumination between PIN pin and liquid crystal panel.
The subject matter that prior art exists is: product is used while working under the environment lower than-20 ° of degree in temperature, easily produces the rainbow bad phenomenon of product color shading.The display of this structure cannot be applicable to northern China and cold district well.Rainbow phenomena is the critical defect of liquid crystal display, directly affects the quality of display effect, is also yield bottleneck and hidden danger character amount principal element in whole liquid crystal display processing procedure.If reasonably do not control rainbow phenomena well, not only cause the waste on material, also can cause very large obstruction to the lifting of whole lcd technology level.Rainbow phenomena mostly shows as the heterochromia of liquid crystal display, thereby display frame is impacted.By technical Analysis, find, the main cause that occurs rainbow bad phenomenon is: in sealing to section set time, the UV of envelope PIN or AB glue are easy to infiltrate through in the outer edge crack of box of the upper and lower glassy layer of liquid crystal display, the UV of envelope PIN after sclerosis or AB glue cause the cold and hot degree of shrinkage of liquid crystal layer in the outer edge crack glue of box and box inconsistent, the thickness of liquid crystal height that occurs liquid crystal sealing edge is uneven, shows that background color difference inequality causes rainbow bad.
Utility model content
The utility model is intended to solve due to the unreasonable caused rainbow bad phenomenon of liquid crystal display sealing.
For this reason, there is the liquid crystal display of rainbow in a kind of pre-anti-pinch PIN that the utility model provides, described liquid crystal panel (1) comprises electro-conductive glass (1a) and lower electro-conductive glass (1c), between described upper electro-conductive glass (1a) and lower electro-conductive glass (1c) by the bonding one-tenth seal box of frame fluid sealant (1d), in described seal box, be provided with liquid crystal layer (1b), one side of the ITO electrode layer of described lower electro-conductive glass (1c) and lower electro-conductive glass (1c) extends to seal box and forms connecting portion outward, key is: outside described seal box, close connecting portion one side is upper, lower electro-conductive glass (1a, between crack 1b), envelope has insulation flexible glue (4), the head of metal PIN pin (2) is clipped on the connecting portion that a little has conducting carbon ink (3), and by envelope UV glue or AB glue (5), metal PIN pin (2) and connecting portion are solidified togather.
Be preferably, described insulation flexible glue (4) is the single-component room temperature vulcanized silica gel of dealcoholized type, is respectively transparent, black or white.
Beneficial effect: the utility model is compared with conventional art, before envelope UV glue or AB adhesive curing, increased first envelope insulation flexible glue technique, first after envelope insulation flexible glue, seal again UV glue or AB glue can effectively stop that UV glue or AB glue penetration are in the crack of upper and lower electro-conductive glass, thus effectively stop because of the rigid rainbow causing after UV glue or AB adhesive curing bad.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the utility model is described in further detail:
As shown in Figure 1, liquid crystal panel 1 is mainly comprised of upper electro-conductive glass 1a, liquid crystal layer 1b and lower electro-conductive glass 1c.Upper electro-conductive glass 1a and lower electro-conductive glass 1c interval arrange, between upper electro-conductive glass 1a and lower electro-conductive glass 1c by the bonding one-tenth seal box of frame fluid sealant 1d, in seal box, be provided with liquid crystal layer 1b, be in the seal box of liquid crystal layer 1b between upper electro-conductive glass 1a and lower electro-conductive glass 1c, the lower surface of upper electro-conductive glass 1a is ITO electrode layer, the upper surface of lower electro-conductive glass 1c is ITO electrode layer, and the ITO electrode layer of upper and lower electro-conductive glass 1a, 1c is by firing point conducting (not shown).The ITO electrode layer of lower electro-conductive glass 1c and a side of lower electro-conductive glass 1c extend to seal box and form connecting portion outward, and on connecting portion, point has conducting carbon ink 3, avoid being arranged between metal PIN pin 2 on connecting portion and connecting portion being firmly connected.
Between the crack of seal box outer upper and lower electro-conductive glass 1a, 1b near connecting portion one side, envelope has insulation flexible glue 4, the head of metal PIN pin 2 is clipped on the connecting portion that a little has conducting carbon ink 3, and by envelope UV glue or AB glue 5, metal PIN pin 2 and connecting portion is solidified togather.Metal PIN pin 2 is " F " shape, and its head is clipped on the connecting portion that a little has conducting carbon ink 3, and lower end is used for connecing PCB drive electrode.
