Display device and method for driving display device

A display device, comprising:

• a display unit, including pixel circuits arranged in a matrix form to form a plurality of rows and a plurality of columns, wherein
• each of the pixel circuits includes j electro-optical elements of different light-emitting colors (j is an integer greater than or equal to 3),
• an operating mode is switchable between
• a time-division driving mode in which image display on the display unit is performed by dividing one frame period into j subframes and performing writing of image data to the pixel circuits on a subframe-by-subframe basis, and bringing, in each of the pixel circuits, electro-optical elements of different light-emitting colors into a light-emitting state on a subframe-by-subframe basis;
• and
• a pause driving mode in which still image display on the display unit is performed at a lower refresh rate than that for when in the time-division driving mode, by repeating a refresh period during which writing of image data to the pixel circuits is performed and a pause period during which the writing of image data to the pixel circuits is brought into a pause state,
• wherein when the operating mode is the pause driving mode, j pixel circuits are considered one group and electro-optical elements of different light-emitting colors in j pixel circuits included in each group are configured to be brought into a light-emitting state, by which a still image with a resolution not more than 1/j of a resolution of an image, displayable on the display unit when the operating mode is the time-division driving mode, is configured to be displayed on the display unit,
• each of the pixel circuits further including:
• j light-emission control transistors including a one-to-one correspondence with the j electro-optical elements;
• and
• a drive current control unit configured to control a drive current for bringing the j electro-optical elements into a light-emitting state,
• the display unit further including
• j light-emission control lines for each row, wherein in each of the pixel circuits,
• control terminals of the j light-emission control transistors are connected to different light-emission control lines,
• first conduction terminals of the j light-emission control transistors are connected to the drive current control unit, and
• second conduction terminals of the j light-emission control transistors are connected to corresponding electro-optical elements,
• wherein when focusing on j pixel circuits included in each group and j light-emission control lines corresponding to the j pixel circuits, each of the focused j light-emission control lines is connected to control terminals of light-emission control transistors corresponding to electro-optical elements of different light-emitting colors in the focused j pixel circuits,
• wherein when the operating mode is the lime-division driving mode, for each row, the j light-emission control lines are configured to be sequentially brought into a selected state on a subframe-by-subframe basis, and
• wherein when the operating mode is the pause driving mode, for each row, only one of the j light-emission control lines is configured to be brought into a selected state.
