摘要： An image display device capable of controlling in a differentiated manner the signal-brightness characteristics of natural pictures and those of different image sources, such as texts, in the screen frame is to be provided. The image display device is provided with a display area in which are arrayed a plurality of pixels each having a light-emitting device whose brightness is controlled with an image signal output voltage supplied from a signal voltage output circuit. The display area comprises first and second pixel groups of pixels connected to different drive voltage lines. The display area has a display characteristic that the first pixel group and the second pixel group are substantially equal in emission spectrum and differ in light emission brightness relative to the same image signal voltage supplied from the signal voltage output circuit.

摘要： A display apparatus is capable of adapting sufficiently to an increase in the display frequency even when using an optical modulation element which has a fairly low response speed and can rewrite an image at a high speed. The display apparatus separately performs mapping of display data for an optical modulation element of each pixel and application of gradation information. The display apparatus divides a display period of one frame into a plurality of sub-frames, controls the input value for the optical modulation element independently per each sub-frame in the plurality of sub-frames, and displays an image with a gradation display using the optical modulation element.
