Abstract

The invention provides a method for forming a color filter, comprising the step of respectively randomly spraying sub-pixel zones in each row. The spraying comprises the steps: randomly selecting oneof spray heads, spraying color photoresist materials to the selected sub-pixel zone with the selected spray head till that the color photoresist materials in the sub-pixel zone reaches the discharge amount of the photoresist required by the sub-pixel zone. The color photoresist materials positioned in the same sub-pixel zone is only sprayed with the same spray head, and the color photoresist materials positioned in the same sub-pixel zones in the each row are sprayed by the at least two spray heads.

Description

technical field [0001] The invention relates to a method for forming a color filter, especially a method for forming a color filter by coating with a plurality of printheads. Background technique [0002] Liquid crystal displays have become the mainstream products in the monitor and thin TV market due to their advantages of thinness, lightness, shortness and power saving. For liquid crystal displays, color filters are one of the most important key components. Only through the filtering effect of color filters can liquid crystal displays display brightly colored images. [0003] As the specifications and sizes of liquid crystal displays continue to increase, the requirements for the characteristics of color filters are also increasing. In terms of the current traditional color filter manufacturing technology, the color filter produced by the pigment dispersion method is more capable. In line with the needs of the current stage, it has become a more common method among variou...
