Background technology
LCD (Liquid Crystal Display in recent years, liquid crystal display) the representative new technique that adopts in manufacturing mainly comprises ODF (One Drop Fill, the injection of dripping), IPS (In-Plane Switching, plane conversion), the two territories of Dual Domain(), HRP (High Resolution Process, high-resolution) etc.Wherein ODF technology be integrated in the past hot pressing, liquid crystal filling, end face seal, liquid crystal cell cleans and the novel efficient technology of a series of technology such as annealing.Can shorten processing step by this technology, reduce thickness of liquid crystal box and shorten the production cycle.
The ultraviolet source of the ultraviolet light polymerization equipment that solidifies for sealed plastic box in the ODF technology at present, is mainly traditional ultraviolet sources such as extra-high-pressure mercury vapour lamp; But along with its extensive use in the LCD manufacturing, traditional ultraviolet light polymerization equipment exposed day by day goes out a lot of shortcomings:
1, traditional ultraviolet light polymerization equipment adopts single face to solidify usually; But the CF(Color Filter due to substrate to be solidified, color film) black matrix and some coating and the TFT(Thin Film Transistor of face, thin film transistor (TFT)) some coating of face all can affect the solidification effect of sealed plastic box, therefore solidifies separately which face and all can not reach perfect solidification effect.
2, traditional ultraviolet light polymerization occupation area of equipment is usually very large, causes the waste in space.
3, in traditional ultraviolet light polymerization equipment, extra-high-pressure mercury vapour lamp emission wavelength China and foreign countries wave-length coverage is large, and thermal discharge is large, and curing efficiency is lower; Simultaneously, wherein visible light and infrared light produce more, and in sealed plastic box the absorbing wavelength scope of light reaction agent between 300nm-400nm, so just mean that extra-high-pressure mercury vapour lamp produces a lot of without effect light, need the longer time of irradiation just can complete curing, not only cause the increase of energy consumption and cost, and be unfavorable for the shortening of production cycle.
4, in traditional ultraviolet light polymerization equipment, extra-high-pressure mercury vapour lamp radiation homogeneity is bad, a little less than the general all luminous intensities than mid portion of the luminous intensity of its lamp tube ends, cause the extra-high-pressure mercury vapour lamp can not uniformly light-emitting, can solidify sealed plastic box like this and cause harmful effect; Simultaneously, because the fluorescent tube of extra-high-pressure mercury vapour lamp adopts discrete mounting structure usually, cause between fluorescent tube and fluorescent tube the position than a little less than just being positioned at the illumination of fluorescent tube upper/lower positions, so also easily to cause sealed plastic box to solidify bad.
In sum, along with the development of LCD manufacturing, traditional ultraviolet light polymerization equipment can not satisfy the demand of production at curing efficiency, solidification effect and space hold etc. aspect a lot.
