    Abstract: A display device includes pixel circuits disposed in rows and columns. A first pixel circuit is configured to emit light of a first color, and a second pixel circuit is configured to emit light of a second color, with the first color preferably being green. A given signal line provides a first image data signal and a second image data signal respectively to the first pixel circuit and the second pixel circuit within a horizontal scanning period, with the first pixel circuit receiving the first image data signal before the second pixel circuit receives the second image data signal.

    Abstract: A display device includes: a sampling transistor sampling a signal voltage of a video signal; a holding capacitor holding the signal voltage sampled by the sampling transistor; and a pixel circuit including a driving transistor that drives a light-emitting portion according to the signal voltage held in the holding capacitor. The light-emitting portion is formed by stacking at least two electro-optic elements, an uppermost electrode is connected to one source or drain electrode of the driving transistor, and a lowermost electrode is connected to a node of a reference potential. A potential of an intermediate node between the uppermost electrode and the lowermost electrode at a time of extinction is set with a potential relation in which the potential of the intermediate node is lower than a threshold voltage of the electro-optic element on a side of the reference potential and is higher than the reference potential.

    Abstract: A color display unit includes subpixels arranged in matrix form. Display pixels are formed from multiple subpixels, one for each of the display colors, grouped together across multiple subpixel rows. Drive units are formed including multiple rows of display pixels that are connected to a common power supply line. Common write scanning lines are provided, where the number of common write scanning lines per drive unit equals the number of rows of subpixels that are included in a display pixel. Each common write scanning line is connected to every pixel of at least one given color in its respective drive unit. The drive units are driven sequentially in a drive-unit-scanning direction. Within each individual drive unit, the write scanning lines thereof are scanned for the signal writing operation sequentially in a scanning direction opposite to the drive-unit-scanning direction.

    Abstract: Provided is a drive circuit that includes a scanning circuit configured to perform a first vertical scanning and a second vertical scanning on each of first and second display regions, adjacent to each other in a vertical direction in a display region including pixels, individually in one frame. The first vertical scanning causes light emission of each pixel to be performed, and the second vertical scanning causes light extinction of each pixel to be performed. The scanning circuit is configured to perform the first vertical scanning and the second vertical scanning to cause timing of starting the light emission of an n+1th frame for a first scanned row, adjacent to the first display region, in the second display region to be later than timing of ending the light emission of an n-th frame for a final scanned row, adjacent to the second display region, in the first display region.
