摘要： A display panel, a display driving method and a display pixel driving circuit therefor are provided. In the display driving method, the light emitting signal includes multiple pulse signals, and the variation trend of the pulse-off durations of the pulse signals is consistent with the variation trend of the light emitting brightness of the light emitting element during the light emitting period, that is, the pulse-off durations decreases sequentially with the decrease of the light emitting brightness of the light emitting element, or sequentially increases with the increase of the light emitting brightness of the light emitting element. Therefore, the flicker problem in the display panel when emitting light can be solved, and improving the image display quality.

摘要： A backplane operative to drive an array of emissive pixel elements is disclosed. Each pixel element comprises a memory cell operative to modulate a plurality of current mirror drive elements configured to drive one emissive element, wherein a plurality of current mirror pixel drive elements may be individually enabled by external control signals. The width W of the reference current FET of a first selectable current mirror circuit will differ from the width W of the reference current FET of a second selectable current mirror circuit. The ratio of the width W of the current source FET to the width W of the reference current FET in a first selectable current mirror pixel drive element is equal to the ratio of the width W of the current source FET to the width W of the reference current FET in a second selectable current mirror pixel drive element.
