20080239165 | BROADCAST RECEIVING DEVICE - A broadcast receiving device includes a receiving component, a comparison component and a drive signal generating component. The receiving component is configured to receive broadcast waves and extract a video signal from the broadcast waves. The comparison component is configured to compare quality of the video signal with a first level. The drive signal generating component is configured to generate a drive signal for displaying video on a display based on the video signal such that at least one of brightness and contrast of the video is reduced by a certain amount when the quality of the video signal is lower than the first level. | 10-02-2008 |
20100231578 | LIQUID CRYSTAL DISPLAY DEVICE - A liquid crystal display device is provided. A plurality of light emitting units includes a plurality of light emitting elements which are configured to emit light toward a liquid crystal panel through a light guide plate. The light emitting units are arranged in series at an interval in such a direction that the light emitting elements face a side surface of the light guide plate. A feeding circuit is configured to supply power to the light emitting units. A first switch is connected to both ends of at least one of the light emitting units such that the at least one of the light emitting units connected between the both ends is deactivated when the first switch is turned on. A second switch is connected to both ends of at least one of the light emitting units such that the at least one of the light emitting units connected between the both ends is deactivated when the second switch is turned on. A switching unit is configured to control an on/off state of each of the first and second switches according to a driving timing of the liquid crystal panel to subsequently switch the light emitting units to be deactivated. | 09-16-2010 |
20110273903 | PLANAR LIGHT-EMITTING DEVICE - A planar light-emitting device includes a light source element and a light guide plate. The light source element is configured to emit light. The light guide plate has a housing hole, a light-emitting face and a light reflecting face. The housing hole houses the light source element. The light reflecting face is formed along a side end portion of the light guide plate. The light reflecting face has an inclined portion that is located next to the housing hole in a first direction of the light guide plate and a flat portion that is located next to the inclined portion in a second direction that is perpendicular to the first direction. The inclined portion has an inclination angle with respect to the flat portion such that the light reflected on the inclined portion is prevented from returning the housing hole. | 11-10-2011 |
20130120340 | LIQUID CRYSTAL DISPLAY DEVICE - A liquid crystal display device includes a liquid crystal cell, a gate driver, a source driver and a controller. The liquid crystal cell has a plurality of source lines, a plurality of gate lines, and a plurality of pixels. The pixels define a pixel region with a set of pixels. The source driver has a plurality of second output lines. The second output lines are connected to source lines to output voltage to the pixels. The source lines have a pair of common source lines that are connected to the set of pixels of the pixel region. The common source lines are further commonly connected to one of the second output lines of the source driver. The controller is further configured to display a predetermined color in the set of pixels of the pixel region. | 05-16-2013 |
20140306873 | BACKLIGHT APPARATUS AND DISPLAY APPARATUS - In a backlight apparatus according to an aspect, a plurality of backlight drivers are connected in cascade arrangement, and when a drive signal is provided to the backlight driver corresponding to one of a backlight group positioned uppermost and a backlight group positioned lowermost in a sub scanning direction Y, each of the backlight drivers delays the drive signal by a predetermined period and outputs the delayed drive signal in order of the arrangement of the backlight drivers. | 10-16-2014 |
20140307200 | DISPLAY DEVICE - A display device includes a display panel and a direct-type first backlight and a direct-type second backlight that each intermittently irradiate light toward a back surface of the display panel and is disposed adjacently in a sub-scanning direction of the display panel. A display area of the display panel comprises a first area provided in a position facing the first backlight and a second area provided in a position facing the second backlight, the first backlight is disposed in a position where the light emitted from the first backlight reaches the first area and the second area, and the second backlight is disposed in a position where the light emitted from the second backlight reaches the first area and the second area. | 10-16-2014 |
20150045356 | PIPERAZINE-SUBSTITUTED BENZOTHIOPHENE DERIVATIVES AS ANTIPSYCHOTIC AGENTS - Provided is a superior, novel heterocyclic compound with improved solubility in oil such as sesame oil and benzyl benzoate, which has a broader treatment spectrum, causes less side effects, and is superior in tolerability and safety, and use thereof. A heterocyclic compound represented by the formula (I) wherein each symbol is as defined in the specification, or a salt thereof. | 02-12-2015 |
20150116743 | IMAGE FORMING APPARATUS, SHEET TYPE DETECTING METHOD AND STORAGE MEDIUM STORING PROGRAM OF SHEET TYPE DETECTING METHOD - An image forming apparatus includes a stopping part, a mode deciding part, a changing part and a type distinguishing part. The stopping part temporarily stops print execution if a type value indicating a type of a sheet conveyed according to the print execution is not included within a given range. The mode deciding part decides whether or not a mode set in the print execution is a specific mode using a different sheet from a sheet used in normal print condition. The changing part changes, if the mode set in the print execution is the specific mode, a width value used for distinguishing the sheet type to a first width value smaller than a normal width value. The type distinguishing part measures the type value and decides whether or not the type value is included within a threshold range defined by the changed width value. | 04-30-2015 |
