摘要： A method of driving a vibration wave motor enables proper frequency control of an AC voltage applied to the motor according to the rotational speed difference between the actual and target rotational speeds of the motor, even if frequency-rotational speed characteristics are not stored in advance. A target rotational speed of a moving member is set. A ratio of an amount of increase or decrease in a rotational speed of the moving member to an amount of update of a frequency of the AC voltage and a rotational speed difference between the target rotational speed and an actual rotational speed of the moving member are calculated. The amount of update of the frequency is calculated by dividing the calculated rotational speed difference by the calculated ratio. The frequency of the AC voltage is updated by using the calculated amount of update of the frequency.

摘要： A driving system of the present invention for use in a displaying device is provided with a pseudo bit-depth extension section. In the pseudo bit-depth extension section, a noise pattern is added to upper-n-bit data of an input signal D0 in m-bit, where (i) m is an integer of 9 or greater, and (ii) n is an integer of 8 or greater, but less than m. Then, upper-n-bit of data D1 thus obtained from the D0 is outputted, as output data D2, from the pseudo bit-depth extension section. The driving system is further provided with an overshoot-driving section for carrying out an overshoot-driving with respect to each of pixels. A noise amount of the noise pattern is 1 or less in 8-bit data, and a calculation in the overshoot-driving section is carried out with n-bit data. With this driving system which adopts a combination of (a) a overshoot-driving method for enforcing liquid crystal to respond at a high speed, and (b) a bit-depth extension technology in which a number of grayscales is increased by adding noise, it is possible to provide, at a low cost, a high-definition displaying device such as a liquid crystal display, having a high-response-characteristics and a high quality of grayscale reproduction.

摘要： A control section divides a display screen into small regions, evaluates the relative brightness of each of the small regions in accordance with color data to be inputted as color data by which each pixel is displayed, and determines whether or not the display screen has a first small region that is brighter than the other small regions by a predetermined degree. Furthermore, the control section causes a first generating means to generate gradation data for use in the first small region, and causes a second generating means to generate gradation data for use in the other small regions. Even if the second generating section receives the same color data as the first generating section does, the second generating section limits the luminance of a W sub-pixel as compared to the first generating section. With this, the first small region can be displayed more strikingly brightly, so that a clearer, more realistic, and more appealing image can be displayed. This makes it possible to realize a display apparatus capable of displaying a clearer, more realistic, and more appealing image.

摘要： Based on each of video data repeatedly supplied to a pixel, a signal processing section generates video data (Dd) for an image display period to be supplied to the pixel and video data (Db) for a blanking period to be supplied to the pixel, and outputs the video data (Dd) and (Db) in a predetermined order. Further, when a gradation transition from a gradation indicated by previous video data (D(i,j,k−2)) supplied to the pixel to a gradation indicated by current video data (D(i,j,k)) supplied to the pixel indicates an increase in luminance, a generating circuit for a blanking period of the signal processing section outputs video data indicative of a gradation which is increased compared with a gradation indicated by gradation data for a blanking period in a steady state, the video data thus outputted being regarded as video data (Db(i,j,k−1)) for a blanking period. This allows for providing a display device capable of displaying moving images with high quality.

摘要： A driving system of the present invention for use in a displaying device is provided with a pseudo bit-depth extension section. In the pseudo bit-depth extension section, a noise pattern is added to upper-n-bit data of an input signal D0 in m-bit, where (i) m is an integer of 9 or greater, and (ii) n is an integer of 8 or greater, but less than m. Then, upper-n-bit of data D1 thus obtained from the D0 is outputted, as output data D2, from the pseudo bit-depth extension section. The driving system is further provided with an overshoot-driving section for carrying out an overshoot-driving with respect to each of pixels. A noise amount of the noise pattern is 1 or less in 8-bit data, and a calculation in the overshoot-driving section is carried out with n-bit data.

摘要： The present invention relates to a hold type display device.One frame period that is a period when an image of one screen is displayed is divided into a dark display period when a relatively dark image is displayed and a bright display period when a relatively bright image is displayed. In the dark display period, each of scanning signal lines (GL1, GL2, GL3, etc.) is driven consecutively two times each during a period corresponding to one third of a conventional one horizontal scanning period. Also, in the dark display period, each two lines of the scanning signal lines (GL1, GL2, GL3, etc.) is driven at the same time. A gradation is calculated for generating a video signal such that, at two pixel formation portions arranged at intersections of these two scanning signal lines driven at the same time and a video signal line, a luminance averaged from luminances originally to be appeared at the two pixel formation portions appears.

摘要： Data, such as video signal data, for example, for a next desired frame is first modulated or varied to facilitate a transition from a current frame to a next desired frame. A modulation processing section can be used, for example, to thus produce a corrected video signal to facilitate the current-to-next desired grayscale level transition. Thereafter, spatial filtering is then carried on the corrected video signal, using a spatial filtering section for example. As such, high frequency components in a spatial domain may be reduced, even after the spatial frequencies of an ordinary video signal and potentially those of noise have been scaled up. Therefore, undesirable noise-caused display quality degradation can be reduced or even prevented, while pixel response speed as a result of the facilitation of grayscale level transition, is increased.

摘要： In a display panel driving apparatus which generates, based on an input gray scale, a gray scale of a first sub-frame and a gray scale of a second sub-frame so as to display the input gray scale as a result of a summation of respective display corresponding to the first sub-frame and the second sub-frame into which one frame is divided, and the gray scale of the second sub-frame being greater than the gray scale of the first sub-frame, for a response in which (i) the input gray scale of a subsequent frame is greater than an input gray scale of a previous frame and (ii) the input gray scale of the subsequent frame is not less than a first threshold gray scale, a gray scale of the first sub-frame in the subsequent frame is set not more than a second threshold gray scale, regardless of input gray scale of the subsequent frame. Thus, it is possible to reduce jaggy in an edge of a moving image in time-division driving.
