Patent number: 9640131Abstract: An overdrive engine generates output frames to be used to drive a display from input frames to be displayed. Each output frame is generated on a region by region basis from the corresponding regions of the input frames. If it is determined that an input frame region has changed significantly since the previous version(s) of the input frame, an overdriven version of the input frame region is generated for use as the corresponding region in the output frame. On the other hand, if it is determined that the input frame region has not changed since the previous version of the input frame, then the new input frame region is used without performing any form of overdrive process on it for the corresponding region in the output frame.Type: GrantFiled: January 26, 2015Date of Patent: May 2, 2017Assignee: ARM LimitedInventor: Daren Croxford

Patent number: 9515130Abstract: A covering method including: preparing a mixture containing insulative material and a solvent; applying the mixture over a defective portion; and covering the defective portion with the insulative material by causing the solvent to evaporate from the mixture. In the covering method, the solvent has a boiling point no lower than 178 degrees Celsius, and in the mixture, a weight ratio percentage of the insulative material to the solvent is no lower than 10%. Thus, the defective portion, which may result in a dark spot, can be efficiently covered with insulative material while ensuring that a non-light-emission area that is formed accordingly has the smallest-necessary size and that sufficient insulation is achieved.Type: GrantFiled: June 20, 2013Date of Patent: December 6, 2016Assignee: JOLED INC.Inventors: Takayuki Shimamura, Asaki Sano, Hideaki Matsushima, Nobuyuki Ishikura
