Abstract:
A display unit (1) includes a light-emitting device (13) and a pixel circuit (12) in each pixel (11), and a drive section (20) configured to drive the pixel circuit (12). The pixel circuit (12) includes a drive transistor (Tr1) configured to drive the light-emitting device (13), and a write transistor (Tr2) configured to control application of a signal voltage corresponding to an image signal to a gate of the drive transistor (Tr1). The drive section (20) performs Vth correction that allows a gate-source voltage of the drive transistor (Tr1) to be brought close to a threshold voltage of the drive transistor (Tr1) on all pixel rows, and then performs writing of the signal voltage corresponding to the image signal to gates of the drive transistors (Tr1) in all pixel rows.

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:
A display apparatus includes: a pixel array section including a row of scanning lines, a column of signal lines, and pixels in a matrix, each of the pixels disposed at an intersection of both of the lines; and a drive section. The drive section performs line progressive scanning on the pixels. The pixel includes a light emitting device, a sampling transistor, a driving transistor, a switching transistor, and a holding capacitor. The sampling transistor samples a video signal in the holding capacitor, the driving transistor changes the device to a luminous state, the switching transistor becomes ON in advance of the sampling of the video signal to change the light emitting device to a non-luminous state, and the sampling transistor takes in the OFF voltage from the signal line to the driving transistor, thereby preventing a penetration current from flowing from the power source toward the fixed potential.

Abstract:
A color display unit includes pixels arranged in matrix form. Display pixel units are formed from multiple pixels, one of each of the display colors, grouped together across multiple rows. Drive units are formed by multiple rows of display pixel units 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 pixels that are included in a display pixel unit. Each common write scanning line is connected to every pixel of at least one given color in its respective drive unit. Within a single drive unit, every pixel of a given color has a transistor whose layout orientation is the same as the layout orientation of a corresponding transistor in every other pixel of that given color.
Abstract:
A driving method of a display device having a driving transistor and a display element, one source/drain region of the driving transistor connected to a power supply part, the other source/drain region connected to an anode electrode provided in the display element, the method includes the steps of: setting a potential of the anode electrode by applying a predetermined intermediate voltage to the anode electrode so that a potential difference between the anode electrode of the display element and a cathode electrode at the other end of the display element does not exceed a threshold voltage of the display element; and then holding the driving transistor in OFF-state while a drive voltage is applied from the power supply part to one source/drain region of the driving transistor.
