20090244667 | HOLOGRAPHIC MICROSCOPE - The preferred embodiments of the present invention include a holography attachment device that is attachable to a digital imaging device to form a holographic microscope. The holography attachment device includes a chamber having at least one attachment mechanism to facilitate attachment of the chamber to a digital imaging device. The holography attachment device also includes a light source and a sample holder section, which is located between a proximate end and the distal end of the chamber. The light source is configured to radiate light within the chamber. The light passes through the sample holder section and impinges on an imaging sensor of a digital imaging device when the chamber is attached to the digital imaging device. The digital imaging device is capable of recording hologram information related to a sample held by the sample holder in the sample holder section. | 10-01-2009 |

20150213626 | GAMUT MAPPING - The present disclosure provides a gamut mapping method. In the gamut mapping method, a plurality of first color points of a first gamut of an image signal is mapped into a plurality of second color points of a second gamut. Each of the plurality of second color points is generated by multiplying each component value of the plurality of primary colors by a corresponding scaling factor. If at least one component value of the plurality of primary colors is zero, the larger a maximum component value of the plurality of primary colors is, the smaller the corresponding scaling factor is. | 07-30-2015 |

20160049129 | DISPLAY APPARATUS AND TOUCH DISPLAY APPARATUS - A display apparatus includes a multiplexer circuit, a driving unit, a first control line and a second control line. The multiplexer circuit includes a plurality of switch units. The first control line is electrically connected with the switch units and the driving unit. The second control line is electrically connected with the switch units and the driving unit. A maximum time constant from the driving unit to the switch units is less than R*C/4, wherein R represents the equivalent resistance of the portion of the first control line between the two switch units which are the farthest from each other, and C represents the equivalent capacitance of the portion of the first control line between the two switch units which are the farthest from each other. | 02-18-2016 |

20150161927 | DRIVING APPARATUS WITH 1:2 MUX FOR 2-COLUMN INVERSION SCHEME - A driving apparatus comprises a plurality of pixels provided in an array employing the 2-column inversion scheme, a 1:2 multiplexer and a data driving unit. Each pixel comprises a plurality of sub-pixels corresponding to different colors respectively. The 1:2 multiplexer coupled to the two pixels multiplexes a data source over one of the sub-pixels in the m column and the other of the sub-pixels in the m+1 column of the same row corresponding to the same color and the same polarity, wherein m is positive integers. The data driving unit is coupled to the 1:2 multiplexer through a plurality of data lines and provides the data source to the 1:2 multiplexer. The data lines do not have to switch between sub-pixels, nor polarity, which is beneficial for power consumption, and for front-of screen performance, which may be influenced by artefacts caused by the switching of the multiplexer. | 06-11-2015 |

20150294985 | DISPLAY PANEL - A display panel is provided. The display panel includes has an active area and a border area surrounding the active area. The display panel includes a plurality of pixels, a plurality of multiplexer portion, a gate driver portion and a source routing portion. The pixels are located in the activate area. The multiplexer portion is located in the border area. The gate driver portion is located in the border area. The source routing portion is located in the border area. In part of the border area, at least part of the multiplexer portion, at least part of the gate driver portion and at least part of the source routing portion are located and sequentially arranged from an internal edge of the border area to an external edge of the border area. | 10-15-2015 |
20150378472 | TOUCH SENSING DISPLAY AND SENSING METHOD THEREOF - A touch sensing display and a sensing method thereof are provided. The touch sensing display includes a touch sensor layer and an active shield layer. The active shield layer includes a plurality of gate lines and a common electrode. The sensing method comprises the following steps. A touch sensing signal is applied to the touch sensor layer during a touch mode period. A gate signal of the gate lines is controlled to be synchronous to the touch sensing signal during the touch mode period. A common signal of the common electrode is controlled to be synchronous to the touch sensing signal during the touch mode period. | 12-31-2015 |
