摘要： Deterioration of the image quality of a moving image which is deteriorated due to a motion-compensated frame rate conversion (FRC) processing is prevented. An image display device comprises an FRC portion (10) for converting the number of frames of an input image signal by interpolating an image signal to which the motion compensation processing is performed between frames of the input image signal and a controlling portion (15) for controlling the operation of the FRC portion (10) after determining whether or not the degree of deterioration of the input image signal is equal to or higher than a predetermined value. The FRC portion (10) comprises a motion vector detecting portion (11e) for detecting a motion vector between frames of the input image signal, an interpolating vector evaluating portion (11f) for allocating an interpolating vector between the frames based on the motion vector information, and an interpolating frame generating portion (12d) for generating an interpolating frame from the interpolating vector. If the degree of deterioration of the input image signal is equal to or higher than a predetermined value, the controlling portion (15) makes the motion compensation of the FRC portion (10) ineffective by setting the motion vector detected by the motion vector detecting portion (11e) to a zero vector.

摘要： The present invention provides an image display apparatus capable of suppressing deterioration in picture quality resulting from precision of detection of a motion vector at the time of performing a predetermined video signal process to improve picture quality. In consideration of reliability in detection of a motion vector mv by a motion vector detector 44, a video signal process in an interpolation section 45, an imaging blur suppression processor 13, and an overdrive processor 10 is performed. Concretely, the video signal process is performed so that a degree of the video signal process rises as reliability increases and, on the other hand, a degree of the video signal process falls off as the reliability decreases. In the case of performing the video signal process using a motion vector, even when a motion vector lies out of a motion vector search range (block matching range), the video signal process according to the motion vector detection precision can be performed.

摘要： A microdisplay (44) having interface circuitry (116) on the same silicon backplane (70) to allow it to receive digital images and video in a variety of formats and convert same to field sequential color signals for generation of full color images. It includes column data processors having a comparator for each block of N-columns of pixels (82). Image data is double-buffered in SRAM (92) memory cells located beneath the pixel electrodes, but not within each pixel. The stored data is logically associated with each pixel via the column data processors. Image compression is accomplished by converting RGB data to a variant of YUV data and sampling the color components of the converted data less frequently than the luminance components. The SRAM image buffer consumes a reduced amount of power. A temperature compensation scheme allows the temperature of the microdisplay to be sensed and the drive voltage to the pixel electrodes to be varied in response thereto.

摘要： A display apparatus comprises a cholesteric liquid crystal display device having cells comprising a layer of cholesteric liquid crystal material and an electrode arrangement capable of providing independent driving of a plurality of pixels across the layer of cholesteric liquid crystal material. A drive circuit generates drive signals supplied to the pixels to drive them into states reflectances in accordance with an image signal. The drive signals may have a waveform shaped to drive the respective pixels into the homeotropic state and the planar state alternately within successive drive periods for respective periods of time which are varied to provide an average reflectance as perceived by a viewer in accordance with the image signal. A light source illuminates the display device and is supplied with power by a power circuit. The power circuit supplies either: a) DC power, or b) AC power at a supply frequency Fs in accordance with the equation |2Fs-FH| ≥FT where FH is the frequency at which the pixels are driven into the planar state. This reduces the perception of flicker in a displayed image and FT is the flicker fusion threshold.

摘要： A light emitting display device using a drive circuit formed of only unipolar thin film transistors, which suppresses effects of characteristic shifts of transistors, and is applicable to large, high-resolution light emitting displays. The device includes a pixel having an organic EL device (LED) and a drive circuit thereof. In a current writing period, the drive circuit sets TFT3, TFT4 and TFT5 ON and sets a ground line and one end of LED to the same voltage through TFT3. A current from a data line is supplied to transistors L-TFT and D-TFT forming a current mirror circuit through TFT4 and TFT5, and a voltage between gate and source terminals of L-TFT and D-TFT is retained in a capacitor. During a LED driving period, TFT3, TFT4 and TFT5 are interrupted, and a current flowing between the source and drain of D-TFT is supplied to LED according to the retaining voltage.

摘要： The present invention relates to a display element drive method performing write at a low speed for still image display and in particular, to a method for driving a display element using cholesteric liquid crystal (electronic paper). The display element includes a plurality of scan electrodes and data electrodes intersecting one another in the opposed state. The drive method executes an empty scan for the scan electrodes before performing an image write process. The scan electrodes are selected in a predetermined sequence and an image write process is performed. According to the drive method, it is possible to suppress a large inrush current generated immediately after the image write. Moreover, it is possible to use a cheap general-purpose driver, apply the method to a cell-less display device, and achieve power saving and a stable display quality.

摘要： An active matrix display device comprises a plurality of pixels, and driving circuitry arranged to drive each pixel with a pre-determined drive voltage level during a first phase (41 ) followed by an overdrive drive voltage level during a second phase (44). A partial frame store is for storing a fraction of the pixel data for the display. Input video data is written into the partial frame store (40) at a first rate and is read out of the partial frame store at a second rate which is greater than the first rate. The data read out of the partial frame store is processed for deriving the overdrive drive voltage level.
