Abstract:
1. A display device comprising: a plurality of pixels arranged in rows and columns for displaying an image during a field having a plurality of subfields, each of the pixels comprising a plurality of light emitting elements having different colors, wherein each of the plurality of light emitting elements is adapted to emit light in response to an applied current; a plurality of select lines coupled to the pixels for applying a plurality of select signals, each of the select lines being coupled to a corresponding one of the rows of pixels to apply a corresponding one of the select signals thereto; a plurality of data lines for applying data signals to the pixels; a plurality of emit lines coupled to the pixels for applying a plurality of emit signals to the pixels, wherein each of the rows of pixels is coupled to a corresponding group of emit lines among the plurality of emit lines; a scan driver configured to provide the plurality of select signals sequentially on all of the select lines to sequentially select all of the rows of pixels during each of the plurality of subfields; and an emit driver configured to apply the emit signals to the pixels for the pixels to start emitting different color lights in a same one of the rows for each of the subfields, wherein the emit driver is configured to apply the emit signals to fewer than all of the emit lines in the group of emit lines corresponding to each row of the pixels in each of the subfields, and wherein each emit line of the group of emit lines corresponding to each row of pixels is configured to selectively control the emitting of at least two of the different color lights in the corresponding row of pixels, wherein each of the pixels further comprises a capacitor for storing a voltage corresponding to one of the data signals applied in response to the corresponding one of the select signals, and a driving transistor coupled to the plurality of light emitting elements for outputting the applied current corresponding to the voltage stored in the capacitor to the plurality of light emitting elements, and wherein, in one of the subfields, at least one of the pixels starts emitting light having a color which is different from a color of a light it starts emitting in another one of the subfields.
