  • Parallax barrier, multiple display device and parallax barrier manufacturing method
    Patent number: 7612834
    Abstract: A parallax barrier is manufactured by forming a light-blocking layer by patterning a metal layer or a resin layer on a barrier glass in a photolithography step. On a mask used in the photolithography step, some pitches between slits are different, the slits corresponding to portions whereupon the light-blocking layers are to be formed. In addition, on the mask, first pitches (for instance, 100) and second pitches (for instance 99.5), which can be actually formed with accuracy, are formed in a cycle, and the average of such pitches can be accord with a theoretical pitch distance (for instance, 99.99). Thus, in the parallax barrier to be used for a multiple display device, visibility of the entire screen can be improved, and the parallax barrier which can be manufactured by using the mask lithography technology having a limited accuracy, and a method for manufacturing such parallax barrier are provided.

  • Optical encoder and electronic equipment having the same
    Patent number: 7612327
    Abstract: An optical encoder of the invention has an OR circuit 21 to which light reception signals A+, B+ are inputted, an OR circuit 22 to which light reception signals A?, B? are inputted, and an AND circuit 23 to which an output signal C of the OR circuit 21 and an output signal D of the OR circuit 22 are inputted. In this optical encoder, a light reception signal A? shifted in phase by 180° from the light reception signal A+, and a light reception signal B? shifted in phase by 180° from the light reception signal B+, are inputted to the OR circuit 22 of the signal processing circuit 15. Thus, the signal processing circuit 15 does not need NOT circuits for inverting the light reception signal A+ and B+. This optical encoder can avoid occurrence of phase differences due to gate delay among signals and detect the mover with signals of excellent duty and periodic precisions.

  • Active matrix substance and display device including the same
    Patent number: 7612839
    Abstract: It is possible to decrease block segmentation and flickering due to separate exposure in an active matrix substrate while avoiding decreased aperture ratio, increased parasitic capacity and complication in manufacturing process. A first pixel circuit and a second pixel circuit including a first-type TFT and a second-type TFT, respectively, are disposed alternately relative to each other in both directions of row and column in an active matrix substrate. In the first-type and the second-type TFTs, a pattern misalignment of the drain electrode with respect to the gate electrode in an up-down direction will increase/decrease a gate-drain parasitic capacity Cgd in reverse ways. By disposing these two types of TFTs in uniform dispersion, the increase/decrease in the parasitic capacity Cgd caused by pattern misalignment occurring at the time of manufacture are averaged.

  • IMAGE ENCODING APPARATUS AND IMAGE ENCODING METHOD
    Publication number: 20090268820
    Abstract: Since a global motion vector detector is disposed on the same chip as, for example, an image converter utilizing spatial correlations, a first problem is that an original frame is not completely reproduced in an image, since the frame to be referred to when detecting the global motion vector is an image obtained by inverse-converting a nonreversibly compression-converted image. A second problem is that, upon high-efficient image encoding, the detection process of the global motion vector is performed even when it is not necessary to detect the global motion vector. An image encoding apparatus is equipped with a mechanism for detecting a global motion vector. The mechanism is located outside an image converter that utilizes spatial correlations, such as high-frequency component removal by a DCT and round-down by a quantization, and variable encoding.
