摘要： In a multiple-output digital to analog converter, digital input data (Dd) is converted into a plurality of analog output voltages (Voi) across associated loads (Li). A timing generator (TG) generates time periods (Ti1) in dependence on the digital input data (Dd). A buffer (B1) has an output (O1) to supply a waveform (WF1) to the loads (Li) via a coupling circuit (S1i). The coupling circuit (S1i) couples a certain load (Li) to the buffer output (B1) during an associated time period (Ti1). The output voltage (Voi) across the certain load (Li) is related to a value of the waveform (Wf1) at the end of the associated time period (Ti1) when the coupling circuit decouples the load (Li) from the buffer output (O1). The multiple-output digital to analog converter further comprises a plurality of dummy loads (Ldi), each one of the dummy loads (Ldi) is associated to a corresponding one of the loads (Li). The dummy loads (Ldi) are coupled to the buffer output (O1) when the corresponding load (Ldi) is decoupled from the buffer output (O1). A pre-setting circuit (B2, S2i) generates the voltages (Vdi) across the dummy loads (Ldi) so as to be substantially equal to the output voltages (Voi) across the associated loads (Li) occurring when the coupling circuit (S1i) decouples the load (Li) from the output buffer (B1).

摘要： A digital signal processing (DSP) method to process rendered text in order to achieve up to 300% of the horizontal resolution on any suitable digital display devices such as LCD, PDP and DLP. When the text is rendered, a single picture element (a “pixel”) of a matrix display screen is actually composed of three “sub-pixels”: one red, one green, and one blue (RGB or BGR). Taken together this sub-pixel triplet makes up what has been traditionally thought of as a single pixel. By staggering and processing the sub-pixel elements horizontally, font resolution is effectively increased to the maximum of 300%. There are three processing steps involved. First, the color image is expanded to a gray scale image having triple the number of horizontal pixels as the original image by interleaving the sub-pixels. Next, a black and white text/graphics (TG) detector is deployed to identify the TG of interest in the gray scale image. Then, the, detected TG and only the detected TG is subject to a morphological thinning operation so that the TG approximates fonts (or graphics) that would be generated from a sub-pixel rendering engine. Finally, the processed TG display data is filtered to minimize color fringing while maximizing its resolution. The resulting display data including the processed TG data and the unprocessed color signals are converted back to the sub-pixels (e.g., RGB or BGR) domain and displayed.

摘要： A display apparatus uses a sub field which illuminates addressed pixels of a display unit to display an image. The display apparatus includes an image signal processing circuit which performs sub field conversion processing on an input image signal, a computational processing circuit which arranges address data of at least one lower sub field of an image displayed on the display unit identical in plural lines, and a drive circuit which addresses and illuminates pixels of the display unit based on the outputs of the input signal processing circuit and the computational processing circuit. An image corresponding to the input image signal is displayed by driving the display unit with the drive circuit when the computational processing circuit performs addressing of the at least one lower sub field simultaneously in plural lines and address periods which select the illuminated pixels of said display unit are shortened.

摘要： A color display device has signal lines arranged approximately in columns and to be supplied with image signals separately for red, green, and blue, scanning lines arranged approximately in rows so as to cross the signal lines, and to be supplied with scanning signals, and a plurality of pixels disposed in the vicinity of the crossing portions of the signal lines and the scanning lines, and to be subjected to writing of image signals when selected according to the scanning signals. Parasitic capacitances are so formed that the amounts of image-signal-related noise entering each of the pixels from the three closest signal lines of red, green, and blue through parasitic capacitance coupling are approximately equal to each other. More specifically, the pixels have a delta arrangement in which three pixels of red, green, and blue belonging to two rows adjacent to each other are located at the apices of a triangle, and the parasitic capacitances are so formed that the amounts of noise entering each of the pixels from the three closest signal lines of red, green, and blue that are two signal lines adjacent to the pixel and located on both sides and one signal line further away are approximately equal to each other. To this end, a light shield film has an extension that overlaps with the signal line further away with the insulating film interposed in between.
