Patent number: 7927771Abstract: A color filter and a fabrication method thereof are provided. In the method, color filter ink that includes wax beads is ejected by an inkjet printing process. A black matrix defining R/G/B pixels is formed on a first surface of a substrate and transparent electrodes are formed on a second surface of the substrate opposite to the first surface at positions corresponding to the R/G/B pixels. The fabricated color filter ink is injected into an inkjet head, and the color filter ink is ejected from the inkjet head into each of the R/G/B pixels. A predetermined voltage is applied between the inkjet head and the transparent electrode such that the ejected color filter ink is precisely injected into each of the R/G/B pixels.Type: GrantFiled: May 11, 2006Date of Patent: April 19, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Ji-hoon Kim, Kye-si Kwon, Jung-yong Lee

Patent number: 7929080Abstract: Provided are a method of adjusting a photonic bandgap of a photonic crystal, a method of manufacturing a reflective color filter using the same, and a display device including the reflective color filter. The method of adjusting a photonic bandgap of a photonic crystal includes forming the photonic crystal having a photonic bandgap on a substrate, and changing the photonic bandgap by irradiating light onto the photonic crystal. In addition, the display device includes a backlight, a transflective liquid crystal panel including liquid crystal cells sealed between first and second substrates. Each liquid crystal cell corresponding to a pixel includes a transmissive area and a reflective area. A transmissive color filter is formed on the first substrate, which faces the backlight, and a reflective color filter is formed on each reflective area.Type: GrantFiled: November 15, 2007Date of Patent: April 19, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Hong-seok Lee, Byoung-ho Cheong, Jin-hwan Kim, Jae-ho You
