摘要： A backlight assembly outputs scan signals having a scanning frequency synchronized with a frame frequency to sequentially drive light emitting blocks providing a light to a display panel. A dimming step of each light emitting block corresponds to one of a plurality of dimming steps in response to local dimming data. A dimming clock having a value obtained by dividing a value obtained by multiplying the scanning frequency and the number is dimming steps by a duty ratio of each scan signal is generated. The dimming step of each light emitting block is counted using the dimming clock, and the counted values are combined with the scan signals to generate dimming signals having a dimming duty ratio corresponding to the dimming step of the light emitting blocks.

摘要： A backlight unit has a Light Emitting Diode (LED). The backlight unit includes a base member, and a light source unit provided on the base member and including p light source blocks, where p is a natural number equal to or greater than 2. The light source blocks are sequentially arranged to emit light, and each of the light source blocks includes at least one LED package. The LED package includes an LED configured to generate light in response to a driving voltage applied from the outside. A main lead is connected to the LED and configured to apply the driving voltage to the LED. At least one sub lead is separated from the main lead and configured to provide the driving voltage to an adjacent light source block.

摘要： In a backlight assembly and a display apparatus having the backlight assembly, a plurality of lamps are housed in a housing having grounded sidewalls, where each of the lamps has at least one bend and series circuits are formed by respective sets of two or more of the bent lamps; where each series connected set of lamps is driven by an AC driving voltage of sufficient magnitude to light the series connected set of lamps, the AC driving voltage being produced by an AC step-up transformer circuit and where each series connected set has its series circuit formed by a lamp-to-lamp connection made through a grounded sidewall of the container. High and low voltage portions of each series connected set of lamps are positioned to reduce electrostatic discharge as between high voltage portions of the series and a nearby grounded sidewall of the container.
