    Abstract: Provided are a display device and a method of controlling a power integrated circuit (PIC) thereof. The display device in one embodiment includes a controller for generating a switch pulse signal synchronized with an input image and initializing the switch pulse signal during a frame blank period in which the input image is not present; and a power integrated circuit (PIC) driven according to the switch pulse signal to generate power of a display panel. A duty ratio of the switch pulse signal is aligned to be greater than 0 and equal to or less than 3% during an alignment period set within a frame blank period, compared with a normal period. Thus, a change in the duty ratio of the switch pulse signal within the frame blank period is controlled to be minimized to prevent a degradation of image quality due to the variation of power.

    Abstract: A display device is disclosed in which a luminance control device includes a temperature sensor that detects a temperature of a display device; an average picture level part that calculates an average picture level, which defines an average brightness of an image input into the display device; and a luminance control part that generates a temperature-dependent peak luminance, which varies with temperature and average picture level, based on a top gain curve defining how a maximum luminance decreases as the temperature of the display device rises and a bottom gain curve defining how a minimum luminance decreases as the temperature of the display device rises, wherein the luminance control part fixes the temperature-dependent peak luminance at a specific luminance level, regardless of changes in average picture level, at a specific temperature in a high-temperature range which is higher than a room-temperature range.
