Abstract: A backlight unit includes a substrate comprising a first area having light source blocks and a second area having light source blocks, and a light source driver disposed on at least one side of the substrate and electrically connected to the light source blocks of each of the first and second areas through each of first and second sensing lines. The first sensing lines electrically connected to the light source blocks of the first area have a first resistance value, and the second sensing lines electrically connected to the light source blocks of the second area have a second resistance value.

Abstract: A display device includes: a display panel; a driving voltage generator; a power voltage generator; an input voltage generator; and a timing controller. The display panel is provided with a pixel configured to emit light by using a driving voltage. The driving voltage generator is configured to supply the driving voltage to the pixel. The power voltage generator is configured to generate power voltages for driving of the display panel by using an input voltage, and generating an input voltage sensing value by sensing the input voltage. The input voltage generator is configured to supply the input voltage to the power voltage generator. The timing controller is configured to control an operation of at least one of the driving voltage generator, the power voltage generator, and the input voltage generator according to the input voltage sensing value.

Abstract: A display device includes a display panel including a plurality of pixels, a scan driver which supplies scan signals and sensing control signals to scan lines and sensing control lines, based on a clock signal, a power manager which applies initialization power to initialization lines, a sensor which senses threshold voltages of driving transistors, a detector which detects an error of the initialization lines and outputs line information indicating an initialization line having the error, a timing controller which changes a sensed threshold voltage using the initialization line having the error and generates image data with reference to a changed threshold voltage, and a data driver which supplies a data signal corresponding to the image data to data lines.
