摘要： The present invention provides a bright and high-resolution display apparatus having a dynamic range exceeding the number of gray-scale voltage (or current) outputs, which a signal driver is capable of generating. In accordance with the present invention, a select period, in which a group of pixels on each row is driven, is divided into a plurality of sub-periods. The signal driver supplies a voltage output varying from sub-period to sub-period to selected pixels through a signal electrode. The pixel is capable of expressing various values of a gray scale, the size of which is at least approximately equal to (the number of gray-scale voltage outputs, which the signal driver is capable of generating)×(the number of sub-periods). By changing the ratio of the length of a sub-period to the length of another sub-period or the range of the driving voltage (or current), the dynamic range of the display can be further increased.

摘要： The present invention reduces smears arising from voltage decreases caused by the wiring resistance of scan lines for electron emission device selection. The display unit includes an FED panel in which scan lines, data lines, and electron supply devices are positioned at the intersections of the data lines and scan-lines. A scan driver for supplying a selection signal to the scan lines, and a data driver for supplying a drive signal to the data lines are provided. Electron emission devices selected by the selection signal are driven by the drive signal. A signal corrector circuit individually corrects the drive signal to be supplied to each data line to compensate for a voltage decrease caused by the wiring resistance in each column of the scan lines.

摘要： To improve luminance uniformity in a panel plane, for example, there is set an amplitude of a pixel driving voltage which is an anode current in the neighborhood of a threshold value of electron emission of one pixel and the amplitude is kept as a threshold value correction value for each pixel, and to correct the luminance variation in the high-luminance emission between the pixels, there is set an amplitude of a pixel driving voltage which is an anode current in the neighborhood of a maximum value of electron emission of one pixel and the amplitude is kept as a gain correction value for each pixel. In the configuration, when a video image is displayed, the input video signal is corrected using the threshold correction value and the gain correction value for each pixel.

摘要： When a video signal is double-speed processed by the first device, a slight vertical deflection process is performed for redundant similar scan lines by the second device, and any slight deflection in the second device is controlled by the first device to enable setting so as to display images with excellent resolution. The first device generates a discrimination signal to designate interlaced scanning and flag a need for vertical scan-line deflection, and such signal is provided to the second device such that the second device can always appropriately determine need for vertical scan-line deflection. Through monitoring for the discrimination signal, an image display apparatus can prevent vertical resolution from deteriorating when video signals possibly requiring vertical line-shifting are inputted from an external source, and can prevent vertical resolution from deteriorating when displaying images of video signals having different systems within different areas on the same screen.

摘要： When a video signal is double-speed processed by the first device, a slight vertical deflection process is performed for redundant similar scan lines by the second device, and any slight deflection in the second device is controlled by the first device to thereby enable setting so as to always display images with excellent resolution. More particularly, a discrimination signal is generated by the first device to designate interlaced scanning and flag a need for vertical scan-line deflection, and such discrimination signal is provided to the second device such that the second device can always appropriately determine the need for vertical scan-line deflection. Through monitoring for the discrimination signal, an image display apparatus is capable of preventing vertical resolution from being deteriorated when video signals possibly requiring vertical line-shifting are inputted from an external source. Further, an image display apparatus is capable of preventing the vertical resolution from being deteriorated when images of video signals having different systems are displayed within different areas on a same screen.
