A selective surface treatment method using a block copolymer, a black matrix and a method of manufacturing the same, and a nozzle plate and a method of manufacturing the same are provided. According to the method of manufacturing a nozzle plate, a block copolymer layer including an ink-phobic polymer block and an ink-philic polymer block may be formed on a stamp, a substrate having nozzles formed therein and an ink-philic coating film formed on an outer surface of the substrate and inner walls of the nozzles may be prepared, and the block copolymer layer formed on the stamp may be transferred onto an upper surface of the ink-philic coating film formed on the outer surface of the substrate.

Method of manufacturing a nozzle plate

A black matrix for a color filter and its method of manufacture include: forming the black matrix in a predetermined shape on a substrate to define a plurality of pixel regions: forming a light shade layer on the substrate, the light shade layer being formed of an ink-philic black material; and forming a Carbon NanoTube (CNT) layer on an upper surface of the light shade layer.

Black matrix for color filter and its method of manufacture

A method of measuring the volumes of ink droplets is provided that includes repeatedly forming print patterns each including a plurality of ink droplets ejected from the inkjet head, photographing ink droplets which correspond to each other in terms of ejection order among the ink droplets of the repeatedly formed print patterns and measuring the volumes of the photographed ink droplets.

Method of measuring volumes of ink droplets and method of controlling nozzles of inkjet head using the method

A method of manufacturing a color filter using an inkjet In the method, a region of the color filter in which a plurality of nozzles are sequentially turned on is a first region, a region of the color filter in which all of the plurality of nozzles are turned on is a second region, and a region of the color filter in which the plurality of nozzles are sequentially turned off is a third region, and when the amount of ink discharged from each nozzle gradually decreases as the number of simultaneously turned-on nozzles increases, the number of ink drops discharged from each of the plurality of nozzles gradually increases in the first region and gradually decreases in the third region to maintain a uniform ink thickness over the entire color filter.

Method of manufacturing color filter using inkjet

A method of fabricating a black matrix of a color filter is provided. In the method, a black matrix layer formed of a hydrophobic organic material is formed on an upper surface of a transparent substrate. A black matrix is formed by patterning the black matrix layer. Side surfaces of the black matrix are made hydrophilic by irradiating a lower surface of the transparent substrate with ultraviolet rays while heating the black matrix. A black matrix provided by the method is also disclosed.
