Abstract: 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.

Abstract: A display apparatus includes a display panel, a gate driver, a data driver, and an emission driver. The display panel includes a pixel. The pixel includes a switching element of a first type and a switching element of a second type different from the first type. The gate driver is configured to output a gate signal to the display panel. The data driver is configured to output a data voltage to the display panel. The emission driver is configured to output an emission signal. The emission signal comprises a length of an emission off duration of a writing frame in which data is written to the pixel and a length of an emission off duration of a holding frame in which the data written to the pixel is maintained in a low frequency driving mode. The length of the emission off duration of the holding frame is different from the length of the emission off duration of the writing frame in the low frequency driving mode.
