  • Publication number: 20170369987
    Abstract: A film forming apparatus includes a chamber that is a container in which a sputter gas is introduced, a carrying unit provided inside the chamber, and circulating and carrying a work-piece on a trajectory of a circular circumference, and a film formation processing unit including a sputter source depositing, on the work-piece circulated and carried by the carrying unit, a film formation material by sputtering to form a film, and a dividing member dividing a film forming position where the film is formed on the work-piece by the sputter source. The dividing member is installed so as to divide the film forming position in a way that, in the trajectory of the circular circumference, a trajectory of passing through a region other than the film forming position performing the film formation is longer than a trajectory of passing through the film forming position performing the film formation.

  • Publication number: 20170103695
    Abstract: A display panel has a first pixel group selected by a first scan line, and second pixel group selected by second scan line. A data line is shared by pixel in the first pixel group and a pixel in the second pixel group. In first scanning period, a driving unit in a circuit device outputs a data voltage with first polarity to the first data line, and outputs data voltage with second polarity, which is polarity opposite to the first polarity, to the second data line. In second scanning period, the driving unit outputs a data voltage with third polarity to the first data line, and outputs a data voltage with fourth polarity, which is polarity opposite to the third polarity, to the second data line. A polarity setting unit in the circuit device sets the first polarity, the second polarity, the third polarity, and the fourth polarity.

  • Publication number: 20160372061
    Abstract: When a 2D display is performed, a controller causes a first selection signal to be in an active state during a given period, and causes a second selection signal to be in the active state during another given period after causing the first selection signal to be in a non-active state. When a 3D display is performed, the controller causes the first selection signal to be in the active state at a given timing point, cause the second selection signal to be in the active state during a period when the first selection signal is in the active state, and thereby cause an overlapping period to arise during a period which is part of a selection period for selecting signal lines corresponding to the first selection signal, and which is part of another selection period for selecting signal lines corresponding to the second selection signal.
