Patent number: 7639513Abstract: An enclosure is formed by folding an FPC board having, on the top face thereof, electronic components and, on the back face thereof, a ground conductor pattern in such a way that the electronic components mounted thereon are housed inside the enclosure. The electronic components housed inside the enclosure are covered with the ground conductor pattern. This means that the enclosure serves as a shield enclosure that electromagnetically shields at least part of the electronic components from the outside. In this way, the shield enclosure is formed by folding the FPC board. This makes it possible to realize an electromagnetic shield structure without using an extra shield case as used in the conventional modules.Type: GrantFiled: September 14, 2005Date of Patent: December 29, 2009Assignee: Sharp Kabushiki KaishaInventor: Terukazu Otsuki

Publication number: 20090315920Abstract: In a display control circuit of this invention, a write gray scale level determining part outputs write gray scale level data for performing overshoot drive on a liquid crystal display device. Moreover, an achievable gray scale level determining part outputs achievable gray scale level data indicating a gray scale level which achieves after a lapse of one frame. Further, an error noise predicting part compares, with a predetermined threshold value, predicted values as differences between gray scale level values of plural pieces of input image data and a mean gray scale level value of these gray scale level values to control a data selecting part such that when at least one of the predicted values exceeds the threshold value, the data selecting part gives, to an image compressing part, the input image data rather than the achievable gray scale level data predicted that a decoding error becomes large. This configuration allows suppression or elimination of after-image noise.Type: ApplicationFiled: June 18, 2009Publication date: December 24, 2009Applicant: SHARP KABUSHIKI KAISHAInventors: Ryoji SAKURAI, Hiroyuki FURUKAWA
