| 20100214474 | VIDEO DEVICE - A video device includes a broadcast signal processor, a display component, a speaker, and a controller. The broadcast signal processor is configured to receive a digital broadcast signal and process the digital broadcast signal. The display component is configured to display video based on the digital broadcast signal outputted from the broadcast signal processor. The display component has a light source. The speaker is configured to output main audio of the video based on the digital broadcast signal outputted from the broadcast signal processor. The controller is configured to determine whether or not the digital broadcast signal includes sub audio for visually impaired. The controller is further configured to output the sub audio for the visually impaired with the main audio of the video from the speaker and turn off the light source of the display component when the controller determines that the digital broadcast signal includes the sub audio for the visually impaired. | 08-26-2010 |
| 20110007104 | LIGHTING DEVICE AND DISPLAY DEVICE HAVING THE SAME - There is provided a lighting device that can reduce the occurrence of both color irregularity and brightness irregularity of light to be irradiated onto an irradiation surface even if one of a plurality of light-emitting elements included in light sources fails to light properly, and a display device using this lighting device. The lighting device includes a plurality of light sources ( | 01-13-2011 |
| 20110080432 | LIGHT EMITTING ELEMENT DRIVE CIRCUIT - A plurality of LEDs are connected in series, and an FET that functions as a constant current source is provided for one end of the serially connected LEDs. Switches are connected in parallel with the LEDs. A switch control circuit controls on and off of the switches independently using switch control signals Xa to Xe, and changes all of the switches from an OFF state to an ON state at the same timing. A drive control circuit may control a gate voltage of the FET to be at low level according to the timing at which the switches change to the ON state. With this, it is possible to adjust luminance of the light emitting devices (LEDs) independently, and to prevent an overcurrent from flowing through the light emitting devices. | 04-07-2011 |
| 20110096099 | BACKLIGHT DRIVE DEVICE, DISPLAY DEVICE EQUIPPED WITH SAME, AND BACKLIGHT DRIVE METHOD - A backlight drive device is provided in at least one embodiment including a plurality of backlight units for each of which a unique address is automatically set using a simplified configuration, in which backlight drive units are sequentially connected to a backlight drive control portion via a serial signal line by a daisy-chain method, and through this, the backlight drive control portion transmits an address-assigning signal sequentially to each of the units before sending luminance data. Also, in at least one embodiment, the backlight drive control portion is directly connected to the backlight drive units via an IIC bus by a bus method, and through this, the backlight drive control portion receives light-quantities and temperatures detected by the units identified by the addresses as mentioned above. This configuration allows automatic setting of unique addresses, which makes it possible to use common backlight drive units. | 04-28-2011 |
| 20110121741 | PLANAR ILLUMINATING DEVICE AND DISPLAY DEVICE PROVIDED WITH SAME - In a backlight device that adjusts brightness by turning on/off switches provided in parallel to respective LEDs, deterioration and breakage of the LEDs, variability in brightness, and flickering are suppressed. In at least one embodiment, a backlight device includes: an LED array including a plurality of LEDs connected in series and bypass switches (transistors) provided in parallel to the respective LEDs; a bypass switch control circuit for switching between an on state and an off state of the bypass switches; an FET having a drain terminal connected to the LED array and a source terminal grounded; a constant current drive control circuit for applying a constant current to the LED array by applying a predetermined voltage to a gate terminal of the FET; and a capacitor whose one end is connected to the gate terminal of the FET and whose other end is grounded. | 05-26-2011 |
