본 발명은 백라이트에 관한 것으로, 그 구성은 다층으로 이루어지는 백라이트에 있어서, 상기 다층 중 도광판의 내부를 수평하게 관통하는 패턴부;를 포함하여 이루어지는 것을 특징으로 백라이트에 관한 것이다. 본 발명은 도광판의 내부를 관통하는 패턴부를 형성함과 동시에 상기 패턴부 내주면을 따라 요철을 형성시킴으로써 광원의 휘도율을 증대시켜 휘도의 균일성 및 안정성을 실현할 수 있는 효과가 있다. 도광판, 패턴부, 백라이트
Abstract:
The present invention relates to a light guide panel and, more specifically, to a light guide panel on which light sources are disposed on an external circumference. The light guide panel comprises: a light incident portion which is the external circumference of the light guide panel; a first dot pattern formed on the central portion of the light guide plate; and an additional second dot pattern disposed between the light incident portion and the first dot pattern. The light guide panel can increase the reflectivity of the light excited from the light sources, and the light guide panel removes a hot-spot phenomenon caused by the light sources spaced apart and more light can simultaneously reach in a liquid crystal panel.
Abstract:
PURPOSE: A resin composition for hard coating is provided to enhance stability and scratch resistance and to prevent blocking phenomenon between laminated films of a thermosetting film. CONSTITUTION: A resin composition for hard coating comprises a reaction mixture which reacts 3-70wt% of organic-inorganic mix nano metal oxide complex sol with ion antistatic agent represented by chemical formula 1; 5-80wt% of photo-crosslinkable polymer resin; 15-90wt% of solvent; and 2-10wt% of photoinitiator. Here, R1-N is a pheterocyclic compound and is selected from imidazole, pyridine, pyrrole, benzopyrrole, pyrazole, isocyazole, interval azole, indole, indazole, iso-indole, delivery rhizin and carbazole. R2 is C1-18 linear alkyl group, and X is selected from CF3SO3, CF3CO2, FPO3, CF2=CFCO2, PF6, BF4, N(CN)2 and N(SO2CF3)2.
