20140071105 | DISPLAY DEVICE - A controller in an intermediate inversion drive mode causes a source driver to alternate polarities of voltages applied to pixel electrodes connected to one of source signal lines per plural gate signal lines, and to apply the voltages so that a pair of the pixel electrodes, which are connected to one of the gate signal lines and to source signal lines adjacent to each other, are subjected to different voltage application in polarity from each other, the source driver alternating polarities of the voltages applied to the respective pixel electrodes for each frame. When the source driver, in the intermediate inversion drive mode, applies the voltages sequentially to the pixel electrodes connected to one of the source signal lines, the controller sets a longer voltage application period for the inverted electrode than for the equivalent electrode. | 03-13-2014 |
20140103384 | LIGHT-EMITTING DEVICE - A light-emitting device includes a semiconductor light-emitting element and a fluorescent member which emits fluorescent light when irradiated with light from the semiconductor light-emitting element.

20140103798 | LIGHT-EMITTING DEVICE - A light-emitting device includes: a package; a semiconductor light-emitting element mounted above the package; a cap component provided above the package; a sealing component which seals a space between the package and the cap component; and a phosphor containing resin including phosphor disposed in the sealed space. | 04-17-2014 |
20140125711 | DISPLAY DEVICE - A display device includes a display portion having an emitting portion, a brightness distribution storage storing brightness distribution information indicating emission brightness distribution of the display portion and target brightness distribution thereof, a first feature amount calculator calculating a first feature amount of the image for judging an allowable corrective increase amount, from a video signal for plural pixels, and a brightness increase processor making corrective increase for the display brightness of the pixels based on the brightness distribution information and the first feature amount. The brightness increase processor judges the allowable corrective increase amount of the display brightness of each of the pixels based on the first feature amount, and makes corrective increase for the display brightness of the pixels corresponding to a low brightness area where the emission brightness distribution of the display portion is lower than the target brightness distribution, based on the allowable corrective increase amount. | 05-08-2014 |
