摘要： A method of driving a display device assumes a specific pixel on a retina that is formed on the retina based on an input image, and controls light emission of each subframe such that luminance of a specific pixel on the retina becomes substantially equal to luminance of a pixel corresponding to the input image. The display device is driven by constructing one frame with a plurality of subframes, for displaying the input image that moves on a display panel.

摘要： A halftone display method utilizes an activation sequence, having a plurality of luminance blocks predefined in each frame or field to display an image and having redundancy, that enables one gray-scale level to be expressed by any one of a plurality of combinations of subframes (luminance blocks). When determining luminance blocks for use to display gray scale of an arbitrary first pixel, the luminance blocks to be used for the first pixel are selected in accordance with a predetermined rule, based on how the luminance blocks are used for a second pixel located in close proximity to the first pixel. In this way, by actively utilizing the redundancy of the activation sequence, the occurrence of moving-image false contours (false color contours) in video can be minimized, and also a motion compensation equalizing pulse method can be effectively applied to further improve the image display quality.

摘要： A method of displaying a dynamic halftone image on a display panel made of pixels divides each frame of the image into subframes and turns on and off the subframes. The method includes the steps of finding a line of pixels that simultaneously display a specific intensity level in a frame and another specific intensity level in the next frame, counting the number of pixels in the line, selecting corrective pulses, which turn on/off corresponding subframes to enable/disable corresponding intensity levels, according to the counted number and a change in the specific intensity levels between the frames, and adjusting original display signals for the pixels in the line according to the corrective pulses, respectively. The method eliminates halftone disturbance and false color contours from the image even if the moving speed of the image on the display panel is high.

摘要： An intraframe time-division multiplexing type display device prevents prominent image defects, such as flicker, and affords a high-quality image display. A single frame of an image is displayed while changing a gray-scale level thereof by means of a number of sub-frames, each sub-frame comprising at least an address period and a sustained discharge period; further, the sub-frames have respective, mutually different sustained discharge periods. A gray-scale level adjustment unit arbitrarily sets the selection sequence of each of the number of sub-frames within an individual frame that is to be in a sustained discharge state.

摘要： A display apparatus, that can prevent thermal destruction and burning with a simple structure, has been disclosed. In the apparatus it is judged that there is possibility of a pattern, whose area with high brightness is small, being displayed frequently, when a state in which the total light emission pulse number remains large occurs with high frequency, and if such a state is detected, the total light emission pulse number (sustain frequency) is reduced to prevent the thermal destruction and burning.
