Description
Technical field
The utility model relates to a kind of device of using that injects liquid crystal in the glass sylphon in making LCD, the injection equipment that the utility model relates to is mainly used in the injection process of common low viscosity liquid crystal, particularly can be applicable to some high viscosity liquid crystal, and environment temperature is hanged down the injection process of common low viscosity liquid crystal under the situation.
Background technology
LCD (LCD) is that a class reaches the purpose of control by liquid crystal layer light by the rotation that control is in the liquid crystal molecule in the electric field, the final electron device of realizing graphic presentation under the synergy of Polarizer.The structure of LCD mainly comprises the alignment film that is carved with the glass substrate of transparency electrode, transparency electrode upper strata and applies in two surfaces, be clipped in the liquid crystal between two-layer alignment film and the Polarizer in the two sheet glass substrates outside.
The displaying principle of LCD is: glass substrate is under cold situation, and the liquid crystal molecule between alignment film does not rotate, and light can be shown as bright attitude smoothly by liquid crystal layer and Polarizer; When glass substrate was connected to external electrical field, liquid crystal molecule rotated under electric field action, and light can not be shown as dark attitude by liquid crystal layer and Polarizer.Need the zone design of display pattern electric field for glass substrate applies, can needing obtain the pattern of demonstration by the rotation of control area of the pattern liquid crystal molecule.Thin Film Transistor-LCD (TFT-LCD) is as active drive controlling LCD, its structure is similar to common liquid crystals display (LCD) with displaying principle, also need to utilize the rotation of liquid crystal molecule to control light, thereby realize pattern displaying by Polarizer.
No matter be common LCD, or TFT-LCD, one includes following steps manufacture process:
Step 1: on glass substrate, make electrode, apply as macromolecular materials such as polyimide at the glass baseplate surface that is carved with electrode again, to form alignment film;
Step 2: use materials such as cotton or woven dacron that friction treatment is made on the alignment film surface, obtain liquid crystal molecule and on alignment film, arrange needed tilt angle;
Step 3: it is rectangular to cut into the parallel empty glass case that links together of the empty glass case of monolithic or a plurality of empty glass case by the glass substrate that alignment film posts face-to-face;
Step 4: in empty glass case, inject liquid crystal, and the sealing liquid crystal injecting port;
Step 5: attach Polarizer in the glass substrate outside, obtain a LCD.
The liquid crystal injection process of step 4 is to make a very crucial operation in the middle of the very long processing procedure of LCD, can be with liquid crystal safety, inject display panel (being empty glass case) cleanly, be directly connected to the display effect and the reliability thereof of LCD.In addition, the operation of liquid crystal being injected display panel is consuming time longer, shortens liquid crystal injection time and has significant to the production efficiency that promotes overall process.
Current thin film transistor liquid crystal display (TFT-LCD) (TFT-LCD) manufacturer becomes the box stage to use liquid crystal drip irrigation (One Drop Fill at display panel, being abbreviated as the ODF technology) technology finishes liquid crystal and injects, this technology is injected liquid crystal and base plate seals is incorporated into an operation and finishes, and has promoted the liquid crystal injection efficiency and the product yield of middle large scale display panel greatly.But the liquid crystal injection device that this technology is used costs an arm and a leg, and therefore common small-medium size LCD manufacturer still adopts traditional empty glass case of making earlier at present, injects the technology of liquid crystal again in empty glass case.The efficient of tradition liquid crystal implantttion technique is subjected to the influence of liquid crystal self character to a great extent, mainly is the viscosity of liquid crystal.(one was with 40mm when normal temperature poured into low viscosity liquid crystal down
2S
-1Be the separatrix, be lower than the low viscosity liquid crystal that is of this value), because the air that dissolves in the liquid crystal is more, eliminate these air and need expend long time, and the bubble explosion time is prone to the problem that liquid crystal is splashed to the liquid crystal injecting port and/or the liquid crystal implanter inwall of sky glass case, cause the high and high consequence of liquid crystal loss of product rejection rate, bring immense pressure to manufacturer's control production cost.In addition, when some high viscosity liquid crystal of perfusion, the problems referred to above are particularly evident.
LCD manufacturer is for promoting the liquid crystal injection efficiency at present, all manage liquid crystal is heated, these methods are that well heater and temperature controller are set on liquid crystal panel mostly, and to putting liquid crystal utensil heating thereon, the liquid crystal utensil of heat is again with the heat transferred liquid crystal by the heat transmission for the liquid crystal panel of heat.These methods are need transmit by heat repeatedly liquid crystal is heated indirectly on the one hand, therefore, working temperature and liquid crystal actual temperature that well heater occurs are not inconsistent, can not accurately monitor the problem of the temperature of liquid crystal, thereby can not farthest reduce the viscosity of liquid crystal; The firing equipment complex structure that is to use on the other hand, bigger to the structural modification of liquid crystal implanter, the fund input height has inconvenience when scrap build and breakdown maintenance.
