Problems solved by technology

[0015] In this way, when the write cycle of image data (display data) is shortened so that some operations must be performed at a high rate, the signal delay due to the time constant relative to CR for writing image data to each display pixel Insufficient writing occurs due to insufficient time, and the CR time constant is caused by the parasitic properties of resistive elements on signal wiring such as display panels and capacitive elements.
Therefore, the level display corresponding to the image data cannot be correctly performed

Abstract

A display apparatus is disclosed. A display panel includes a plurality of display pixels arranged at intersections of a plurality of scanning lines and a plurality of data lines. A scanning drive unit sequentially applies a scanning signal to each of the scanning lines and sets the corresponding display pixels to a selection state. A data drive unit generates a gradation signal corresponding to the display data and supplies the gradation signal to the display pixels. A power source drive unit supplies to the display pixels a drive voltage for controlling a drive state of each of the display pixels. A drive control unit controls the power source drive unit to operate to set the display pixels to a non-display operation state during a non-display period, and controls the scanning drive unitto operate to set the display pixels to the selection state during the non-display period.

Description

technical field [0001] The invention relates to a display device and a display driving method thereof. In particular, the present invention relates to a display device provided with a display panel having a plurality of current-controlled optical elements disposed thereon to display image information and a driving control method thereof. Background technique [0002] In recent years, light-weight and thin display devices that consume a relatively low amount of electric power have become popular as monitors and displays for personal computers and video equipment. In particular, liquid crystal display (LCD) devices are widely used as display devices for mobile phones, digital cameras, personal digital assistants (PDAs), and portable devices (mobile phones) such as electronic dictionaries. [0003] As a next-generation display device following such an LCD device, research and development has been carried out toward the full spread of a self-luminous display device (self-lumino...
