Abstract: A display device according to an embodiment of the specification includes a display panel including a pixel including a driving element and a light emitting device; a host system configured to render image data, which is to be applied to the pixel, change a length of a vertical blank period, and output a rendering completion signal prior to outputting the rendered image data; a timing controller configured to set a sensing period on the basis of the rendering completion signal in the vertical blank period; and a sensing circuit configured to sense an electrical characteristic of the driving element in the sensing period, wherein the sensing period starts at a first timing which is a predetermined time earlier than an end time of the vertical blank period, and a length of the predetermined time is fixed regardless of a length variation of the vertical blank period.

Abstract: A timing controller includes an input signal processor that receives a data enable signal and a frame frequency information signal, generates one of a first internal data enable signal having a first frame frequency and a second internal data enable signal having a second frame frequency, the first and second frame frequencies being selected based on the frame frequency information signal. A gate control signal output unit generates and outputs a first gate control signal based on the first internal data enable signal or a second gate control signal based on the second internal data enable signal. A data control signal output unit generates and outputs a first data control signal based on the first internal data enable signal or a second data control signal based on the second internal data enable signal. The pulse widths of the first and second internal data enable signals are the same.
