    摘要: According to this invention, a panel controller converts display data having 64 gray scale levels for a color CRT output from an RAMDAC into display data having 57 gray scale levels to perform display driving of a color LCD. The panel display controller has a function of generating 7 intermediate pseudo gray scales between the base frames of R, G, and B signals by a frame rate control method in the color LCD having 8 base gray scale levels of each of the R, G, and B signals to generate (180K colors) display data having 57 gray scale levels and a function of generating 3 intermediate pseudo gray scales between the base gray scales of the signals by a dither method to generate (24K colors) display data having 39 gray scale levels. The selection of the frame rate control or the dither method and the selection of the 512-color, 180-K-color, or 24-K-color display are arbitrarily performed, or these selection operations are automatically performed in accordance with a display mode.

    摘要: A value obtained by adding a back porch period following a vertical sync signal output from a CRT controller to the total number of horizontal display lines of a display resolution is set in a register. A counter counts the value set in the register in synchronism with a horizontal sync signal, and outputs a scanning start signal to a Y driver. With this operation, when a designated display resolution is lower than the physical resolution of an LCD, the scanning start signal is output before scanning of all the physical display lines of the LCD is completed. As a result, upper and lower non-display portions on the LCD display screen are simultaneously scanned.

    摘要: A VGA controller has a pass through mode and VRAM mode as motion picture display modes, and one of these display modes can be selected by controlling a switch. In the pass through mode, video data input from a video port interface can be directly output to an NTSC/PAL encoder without the intervention of a VRAM. In this mode, original video data can be displayed on a TV with its original quality. On the other hand, in the VRAM mode, the refresh rate for screen display is matched with the vertical sync frequency of video data, and a high-quality image free from any “tearing” can be obtained.

    摘要: In a personal computer system which is equipped with a plasma display unit as a standard I/O device having a horizontal resolution of 640 dots and which can arbitrarily be connected to a CRT display unit having a horizontal resolution of 720 dots, a high-resolution display system includes a display timing data register suitable for the horizontal resolution of the CRT display unit. The display timing data stored in the display timing register is converted into display timing data having a horizontal resolution of 640 dots by a display timing converter. The converted timing data is stored in a clock management register, a clock mode register, and a horizontal panning register in a CRT controller. The high-resolution display system includes a circuit responsive to read access of the respective registers for transferring to a CPU the display timing data which has a horizontal resolution of 720 dots and which is stored in the display timing data register.

    摘要: A display control apparatus in a system which is equipped with a plasma display unit as a standard I/O device and which can arbitrarily be connected to a monochromatic or color CRT display unit, includes a CRT palette in which gradation or color data is set from a CRT-BIOS, a PDP palette in which PDP gradation data is set, an arithmetic circuit for performing a predetermined arithmetic operation of the color data from the CRT palette and outputting gradation parameters, and a conversion table for storing a correspondence between the PDP gradation data and the CRT gradation data or the gradation parameters. The CRT gradation data set in the CRT palette is converted into PDP gradation data by the conversion table for storing the correspondence between the CRT gradation and the PDP gradation. The color data set in the CRT palette is subjected to a predetermined arithmetic operation by the arithmetic unit, thereby generating the gradation parameters. The parameters are converted into the gradation data by the conversion table for storing the correspondence between the CRT gradation parameters and the PDP gradation data. The converted data is set in the PDP palette.

    摘要: According to this invention, in a display system having a CRT controller for arbitrarily and selectively display-driving a plasma display and a CRT display, display fonts inherent to the displays are prepared, and a display font corresponding to the display is selectively used and displayed in accordance with a display to be display-driven. The fonts include a plurality of types of graphics and text fonts, and are selectively used. As the text font, a single font and a double font are selectively used. When a display mode of the plasma display having a ratio of the number of dots in the vertical direction to that in the horizontal direction different from that of the CRT display is set, a specific raster of the display screen is scanned twice to stretch an image.

    摘要: Full-motion video data with a sub-picture and sound is recorded in a DVD-ROM drive. The DVD-ROM drive is connected to an ATAPI interface. Using a data buffer of the ATAPI interface, an MPEG stream is transferred to an MPEG2 decoder on the system board at a variable rate, and video data, audio data, and a sub-picture included in the MPEG stream are decoded by the MPEG2 decoder incorporated in the system. The decoded sub-picture is drawn in a VRAM as in normal VGA graphics. The sub-picture image drawn in the VRAM is synthesized with the video from the MPEG2 decoder by a multimedia display controller and displayed on a screen.
