摘要： A flicker quantification system includes a display device driven in units of reference periods having a first frame for writing data and at least one second frame for holding data. A luminance measurer generates luminance data by measuring a luminance of a display during the reference period. A voltage measurer measures a voltage of a photo sensor corresponding to light emitted. First voltage data representing an accumulation amount of voltage during the first frame and second voltage data representing an accumulation amount of voltage during the at least one second frame is generated. A processor calculates a flicker index value representing a ratio of a measured luminance difference to a just noticeable difference, based on the luminance data, the first voltage data, and the second voltage data. The measured luminance difference may represent the difference between a luminance during the first frame and a luminance during the second frame.

摘要： A pixel includes: a first transistor including a gate electrode electrically connected to a first node, a second node to which a first power voltage for driving the light emitting element is applied, and a third node electrically connected to the light emitting element; a first emission control transistor having an on-off timing controlled by a first emission control signal; and a second emission control transistor having an on-off timing controlled by a second emission control signal. A time interval exists between a time at which the first emission control signal having a turn-on level is input such that a voltage of the second node is dropped from a bias voltage having a voltage level higher than a voltage level of the first power voltage and a time at which the second emission control signal having a turn-on level is input.

摘要： A display device comprises pixels, an emission control driver, a scan driver, and a timing controller for selecting whether the display device is to operate in a first display mode in which the display device is driven at a first frequency or a second display mode in which the display device is driven at a second frequency lower than the first frequency based on input image data. The first display mode comprises first frame periods, and the second display mode comprises second frame periods having at least two sub-frames having a period equal to the first frame period. A total time required to supply the scan signals to the scan lines in one first frame period of the first frame periods and a total time required to supply the scan signals to the scan lines in one second frame period of the second frame periods are substantially same.

摘要： A display system includes: a host processor which outputs first image data and outputs scan frequency information and a partial scan enable signal, based on an image driving frequency; a display module controlled by the host processor; and an interface. The display module includes: a display driving circuit which controls a selection of pixel rows to which the data signals are supplied based on the scan frequency information and the partial scan enable signal; and a display panel which displays an image on selected pixel rows based on the data signals. In a video mode of the interface, the host processor divides and outputs the first image data through the interface during transmission periods, based on the image driving frequency, and suspends an output of the first image data through the interface during suspend periods.
