| 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 |

| 20100097541 | LED BACKLIGHT AND LIQUID CRYSTAL DISPLAY DEVICE - An LED backlight in which deterioration in in-plane uniformity of brightness is prevented, whose thickness, frame width, and wire length are reduced, and in which wiring can be carried out easily, includes an LED provided on one surface of an LED substrate; the LED substrate is mounted on a chassis panel so that a surface of the LED substrate opposite to the one surface contacts the chassis panel; and the chassis panel has a connection hole provided in a portion of a region of the chassis panel in which region the LED substrate is mounted, which passes through the chassis panel. | 04-22-2010 |
| 20100271565 | ILLUMINATION DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE - An illumination device includes an LED package, an LED driver including an FET, and a thermistor disposed on a substrate. A plurality of such LED packages are disposed on the substrate such that a first area and a second area, each determined by vertices corresponding to LED packages, are defined on the substrate. The thermistor is disposed in the first area, and the FET is disposed in the second area, which is outside of the first area. The thermistor detects a temperature in the first area. Such a configuration allows the thermistor to detect, in accordance with the temperature in the area, the temperature of heat transferred from the LED packages, without being affected by heat generated by the FET. This makes it possible to efficiently make temperature corrections to stabilize color temperature and luminance. | 10-28-2010 |
