Patent number: 9478183Abstract: In this liquid crystal display device, a potential propagation line (PVID) and video signal lines SL(1) to SL(M) are connected via coupling capacitive elements Cp(1) to Cp(M), and a capacitance drive circuit (100) causes the potential of the potential propagation line (PVID) to change in the same direction in which the potential of a video signal S(m) varies during a period of nonselection. As a result, even if there is not enough time to perform a precharge operation, the potentials of video signal lines can be similarly raised or lowered without performing a precharge operation.Type: GrantFiled: April 9, 2012Date of Patent: October 25, 2016Assignee: Sharp Kabushiki KaishaInventor: Nobuhiro Kuwabara

Patent number: 9478186Abstract: When an idle period is started, a voltage of the control signal is changed from a value H to a value L. As a result, the analog amplifiers provided in the signal line driver circuit are switched from the normal state to the low-driving power state. At this time, the data signal lines are set to have a constant potential. A gate voltage is changed from Vgh to Vgl at the same time as when the control signal was changed from the value H to the value L. As a result, the gate of each TFT returns to the OFF state from the ON state. The control signal remains at the value L until the idle period is over. In other words, when the next driving period is started, the voltage of the control signal is changed from the value L to the value H. As a result, the analog amplifiers in the signal line driver circuit are switched back to the normal state from the low-driving power state.Type: GrantFiled: October 21, 2011Date of Patent: October 25, 2016Assignee: SHARP KABUSHIKI KAISHAInventors: Jun Nakata, Kohji Saitoh

Patent number: 9478187Abstract: Two gate drivers each comprising a shift register and a demultiplexer including single conductivity type transistors are provided on left and right sides of a pixel portion. Gate lines are alternately connected to the left-side and right-side gate drivers in every M rows. The shift register includes k first unit circuits connected in cascade. The demultiplexer includes k second unit circuits to each of which a signal is input from the first unit circuit and to each of which M gate lines are connected. The second unit circuit selects one or more wirings which output an input signal from the first unit circuit among M gate lines, and outputs the signal from the first unit circuit to the selected wiring(s). Since gate signals can be output from an output of a one-stage shift register to the M gate lines, the width of the shift register can be narrowed.Type: GrantFiled: May 18, 2015Date of Patent: October 25, 2016Assignee: Semiconductor Energy Laboratory Co., LTD.Inventors: Hiroyuki Miyake, Kouhei Toyotaka

Patent number: 9478193Abstract: Light from an array of laser light sources are spread to cover the modulating face of a DMD or other modulator. The spread may be performed, for example, by a varying curvature array of lenslets, each laser light directed at one of the lenslets. Light from neighboring and/or nearby light sources overlap at a modulator. The lasers are energized at different energy/brightness levels causing the light illuminating the modulator to itself be modulated (locally dimmed). The modulator then further modulates the locally dimmed lights to produce a desired image. A projector according to the invention may utilize, for example, a single modulator sequentially illuminated or separate primary color modulators simultaneously illuminated.Type: GrantFiled: March 14, 2012Date of Patent: October 25, 2016Assignee: Dolby Laboratories Licensing CorporationInventor: Martin J.
