Abstract
The invention relates to a color filter inter-pixel separating wall, made from polysiloxane or its derivatives, which comprises alkyls or phenyls, and organic functional groups containing C, H, O or N. And it can change wetting property of ink and separating wall interface to make pigment in the ink distributed more uniformly in the pixels and at the pixel boundaries.
Description
[technical field]
The present invention relates to dividing wall and manufacture method thereof, colored filter and manufacture method thereof between a kind of colored filter pixel.
[background technology]
Because LCD (Liquid Crystal Display, LCD) be the element of non-active illuminating, must see through inner backlight light source is provided, the GTG that collocation drive IC and liquid crystal control form black, white dichromatism shows, red (R), green (G), indigo plant (B) three kinds of color layers of seeing through colored filter (Color Filter) again provide form and aspect, form colored display frame, so colored filter is the key part and component of LCD colorize.
At present, the colorful optical filter preparation method of prior art mainly contains: pigment dispersion method (Pigment-dispersed Method) and ink ejecting method (Ink Jet Method).
Pigment dispersion method is that chromatic photoresist (Color Resist) is coated on the substrate in the mode that rotation applies, and is prepared into color lump (Color Area) via the mode of exposure imaging.Chromatic photoresist is that color pigment is dispersed in wherein photoresistance, has the characteristic of irradiation reaction and thermmohardening.The resistance of RGB three color coloured light must form colored filter at last through three road coatings, exposure, developing manufacture process.Pigment dispersion method is replaced by ink ejecting method gradually owing to processing procedure complexity and the high shortcoming of equipment cost.
Ink ejecting method is injected in the black matrix" on the substrate simultaneously for the ink that uses an ink discharge device and will contain the RGB color layers, and the dehydrated back of ink droplet forms painted RGB color layers pattern on this substrate.Use ink ejecting method can once form the RGB color layers, make preparation process simplify in a large number, cost significantly reduces.So ink ejecting method has the plurality of advantages of processing procedure simplification, environmental protection, conservation.
