摘要： In one embodiment of the present invention, in the case of dark display on sub-pixels, a sub-frame processing section is disclosed which sets video data for a sub-frame to a value falling within the range for dark display, and increases or decreases video data for a sub-frame so as to control luminance of the sub-pixels. In the case of bright display, the sub-frame processing section sets video data to a value falling within the range for bright display, and increase or decreases video data so as to control luminance of the sub-pixels. A modulation processing section corrects video data of each frame and then outputs corrected video data to the sub-frame processing section. Also, the modulation processing section predicts luminance that the sub-pixels reach at the end of the frame and then stores prediction results for correction and prediction in the subsequent frame. This realizes a display device which is brighter, has a wider range of viewing angles, restrains deteriorated image quality caused by excessive emphasis of grayscale transition, and has improved moving image quality.

摘要： In a liquid crystal display apparatus realizing a dual view display by bonding a liquid crystal panel and a parallax barrier, the parallax barrier separates display images by treating three pixels including R, G, and B pixels as one unit (one picture element). At this time, luminance variation due to crosstalk concentrates on a right-end pixel among the three pixels constituting the one picture element (in a case where each pixel receives data from a source line immediately on the left of the pixel). Accordingly, the right-end pixel is arranged to be a B pixel that has a low correlation with luminance information and in which influence of crosstalk is hard to be viewed. Further, an applied voltage to be supplied to the display pixel of the B (blue) color and an input gradation are set to have a relationship along a γ curve that makes luminance variation difficult to occur in a low luminance area.

摘要： There is provided a motion-adaptive grayscale level converter section between a video signal source and a pixel array. The pixel array includes a liquid crystal cell of normally black and vertically aligned mode. The motion-adaptive grayscale level converter section determines based on information from a decoder section whether the pixels of an image represented by a video signal is in a moving image area. If a pixel is in a moving image area, the motion-adaptive grayscale level converter section changes the grayscale level data representing the grayscale level of the pixel so that there is no darker grayscale level than a predetermined first grayscale level. The resultant data is output as a video signal. Accordingly, we can provide a liquid crystal display capable of easing image quality degradation due to insufficient response when displaying a moving image while maintaining the contrast ratio achieved for a still image display.

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： In one embodiment of the present invention, when an image is displayed in an image display device which has a frequency of 50 to 70 Hz in one frame period, a control LSI is set so that, in the case where the frame average luminance of a pixel is in the range of 150 [cd/m2] to 350 [cd/m2], the contrast ratio between subframe periods is set to: a range of not greater than 50 and not smaller than 1.5 when the luminance is 150 [cd/m2]; a range of not greater than 3.5 and not smaller than 1.5 when the luminance is 200 [cd/m2]; a range of not greater than 2.2 and not smaller than 1.5 when the luminance is 250 [cd/m2]; a range of not greater than 1.8 and not smaller than 1.5 when the luminance is 300 [cd/m2]; 1.5 when the luminance is 350 [cd/m2], and, for a frame average luminance other than the frame average luminance in the range, the contrast ratio is set so as to be monotonously changed between the contrast ratios corresponding to the respective frame average luminance. As a result, flicker visibility can be prevented and moving image blur can be suppressed, thereby realizing an image display device that can display a moving image with high quality.

摘要： Provided are data lines, scanning lines crossing the data lines, and a switching element in vicinity of each intersection of the data lines and the scanning lines, the data lines being connected via the switching elements with pixel electrodes arranged in matrix. Direct-type backlights arranged in parallel with the scanning lines are provided, and a backlight turning-ON drive circuit for turning the direct-type backlights in order at a predetermined frequency in sync with a scanning signal is provided. In at least one embodiment, the backlight turning-ON drive circuit includes a controller for controlling the direct-type backlights to turn ON in order in sync with the scanning signal in such a manner that the direct-type backlights are turned ON discretely over frames being continuous based on a vertical sync signal.

摘要： A control section is disclosed which 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 device to generate gradation data for use in the first small region, and causes a second generating device 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： An edge detecting circuit detects whether a particular pixel belongs to an edge by determining whether the differential value of the pixel from the neighboring pixel is equal to or greater than a threshold. Based on the detection result, an emphasis converter stops OS drive when the image of a pixel area is regarded as an edge image in accordance with the detected result of the edge detecting circuit and implements OS drive when the image of a pixel area is not regarded as an edge image. In this way, the edge detecting circuit detects edge portions of the input video, whereby OS drive in the emphasis converter can be controlled so as to be turned on and off.

摘要： In one embodiment of the present invention, a large-screen or high-definition LCD is provided with its display quality improved significantly by reducing the viewing angle dependence of γ characteristic. Each pixel includes first and second subpixels, to which different voltages are applicable. The device further includes electrically independent storage capacitor trunks, each being electrically connected to the respective storage capacitor counter electrodes of either the first or second subpixels through storage capacitor lines. One vertical scanning period (V-Total) of an input video signal is divided into at least two subframes, in each of which a display signal voltage is written on each pixel. Two consecutive vertical scanning periods of the input video signal include a sequence in which the display signal voltage is written at the same polarity in two consecutive subframes and then has its polarity inverted in the next subframe. A storage capacitor counter voltage has, in each subframe, a first waveform, oscillating in a first cycle time PA, which is an integral number of times (and at least twice) as long as one horizontal scanning period (H), and a second waveform, defined such that the effective value of the CS voltage storage capacitor counter voltage has a predetermined constant value every predetermined number of consecutive vertical scanning periods of the input video signal. Between two subframes in which the polarity of the CS voltage is inverted, the first waveforms of the CS voltage storage capacitor counter voltages have a phase difference of 180 degrees.
