Patent number: 9653013Abstract: Provided is a liquid crystal display device that can suppress, more than the prior art, lowering of display quality when low-frequency drive is being carried out. The liquid crystal display device is operated in a low frequency drive mode. A source driver applies a gradation voltage during write periods and an idle period voltage during an idle period to each source line. The value of the idle period voltage is, for example, an average value of a maximum gradation positive voltage, a maximum gradation negative voltage, a minimum gradation positive voltage, and a minimum gradation negative voltage. By making the voltage for each source line during the idle period be the idle period voltage, potential variations in the source lines when switching from the write periods to the idle period are smaller than the prior art.Type: GrantFiled: May 21, 2013Date of Patent: May 16, 2017Assignee: SHARP KABUSHIKI KAISHAInventors: Hidekazu Miyata, Tadao Morishita

Patent number: 9625580Abstract: A method for developing a map of objects in a region surrounding a location is disclosed. The method includes interrogating the region along a detection axis with a series of optical pulses and detecting reflections of the optical pulses that originate at objects located along the detection axis. A multi-dimensional map of the region is developed by scanning the detection axis about the location in at least one dimension. The reflections are detected via a single-photon detector that is armed using a sub-gating scheme such that the single-photon detector selectively detects photons of reflections that originate only within each of a plurality of zones that collectively define the detection field. In some embodiments, the optical pulses have a wavelength within the range of 1350 nm to 1390 nm, which is a spectral range having a relatively high eye-safety threshold and a relatively low solar background.Type: GrantFiled: January 3, 2014Date of Patent: April 18, 2017Assignee: Princeton Lightwave, Inc.Inventors: Evgenii Yuryevich Kotelnikov, William Paul Mordarski, Igor Kudryashov, Mark D.

Patent number: 9581843Abstract: At the time of partial drive, the levels of voltages applied to data lines SL1 to SLn are switched according to a rewrite frequency set for each region of a display screen. For example, in a still-image display region with a relatively low rewrite frequency, the levels of the voltages applied to the data lines SL1 to SLn are set to be higher than those for a moving-image display region with a relatively high rewrite frequency. By this, the same effect as that obtained when a counter voltage is switched according to the rewrite frequency can be obtained. Thus, flicker occurring in each region of the display screen can be suppressed.Type: GrantFiled: September 20, 2012Date of Patent: February 28, 2017Assignee: SHARP KABUSHIKI KAISHAInventors: Seiji Kaneko, Kaoru Yamamoto, Yasuyuki Ogawa, Kohhei Tanaka, Seiichi Uchida, Yutaka Takamaru, Shigeyasu Mori
