摘要： Exemplary embodiments include a backlight assembly for a display wherein the backlight assembly is comprised of a plurality of tiles. Each tile has a plurality of lights attached to it, such that when a single light or group of lights fail, the tile may be replaced without having to replace the entire backlight assembly. The current draw and/or illumination of each tile is calibrated and maintained throughout the life of the display to ensure a uniform distribution of light across the backlight assembly.

摘要： An improved electrical circuit design and method to drive a plurality of LEDs in an LCD backlight in order to produce a uniform color distribution across the entire viewable surface of the display. The embodiments disclosed have features that permit a predetermined reduction in the amount of current provided to the LEDs positioned along the edge of the display region. This results in color uniformity, and consequently, an improved picture quality.

摘要： Embodiments comprise a backlight device and a method for controlling the chromaticity and/or luminance of the backlight device. More particularly, embodiments relate to a backlight device for a display which utilizes an array of LED pairs to create a desired chromaticity and luminance of light, whereby the chromaticity and luminance can be closely monitored and maintained throughout the life of the display. A pair of LEDs are used in an exemplary embodiment where the pair contains two blue LEDs with the first LED coated in a red phosphor and the second LED coated in a green phosphor.

摘要： A switchable power supply includes a moveable electrical plug holding member that has a first position, which places an electrical plug pair in position for use with a first voltage standard, and a second position, which places the electrical plug pair in position for use with a second voltage standard. A switch is in a first state when the moveable electrical plug holding member is in the first position and is in a second state when the moveable electrical plug holding member is in the second position. When the switch is in the first state, a voltage modifier circuit generates a first output voltage and when the switch is in the second state, the voltage modifier circuit generates a second output voltage.
