Abstract: There are provided motherboard 7, signal line 12 formed on motherboard 7, multiple ground lines 13 formed spaced apart and substantially in parallel with each other adjacent signal line 12, card board 10, signal line 14 formed on card board 10, multiple ground lines 15 formed spaced apart and substantially in parallel with each other adjacent signal line 14, and line connector 9, and signal line 12 and signal line 14 are connected by conductor 16 in connector 9, while ground lines 13 and ground lines 15 are connected by conductor 17 in connector 9. Radio frequency module 11 is connected to signal line 14, and signal line 12 is connected to an antenna through radio frequency receptacle 8. A radio frequency signal is transmitted through signal line 12, conductor 16, and signal line 14 with a low insertion loss.

Abstract: In a notebook type computer terminal, a plate type slot antenna is provided between a display panel and a surrounding wall of a display panel housing so that a radiator portion thereof is projecting from a frame of the display panel and a stay, which are made of conductive material by a length more than a predetermined dimension S. A ground portion of the antenna is connected not only to a ground of a radio transceiver unit but also to the display panel housing made of conductive material through the stay.

Abstract: This invention relates to a video graphic control method and controller for sending to a display device graphic data from a processing device, and the object thereof is to provide a video graphic controller that increases the bandwidth available to a graphic engine or CPU without increasing power consumption or manufacturing costs, even when used with a conventional frame memory. A video graphic controller for controlling video data by storing the video data from a CPU 4 in a frame memory 18 and causing the frame memory 18 to output the data to a display device 30 uses a video data comparison means 20 to compare a piece of video data stored in the N-th address of the frame memory 18 to another piece of video data stored in the N-1-th address in order to determine whether the two pieces of data match, and if the two pieces of data match, outputs to the display device 30 the piece of video data stored in the N-1-th address instead of the piece of video data stored in the N-th address.

Abstract: Screen interpolation is done without using an expensive line buffer, etc., to enlarge and display an original image without incongruity. Rather than computing an interpolated pixel value as an average of adjacent pixel values and displaying the computed average pixel value in each frame, in accordance with this invention a pixel to be interpolated assumes one of the adjacent pixel values in each frame, but in successive frames assumes different adjacent pixel values in a mix such that the average value of the interpolated pixel over many frames becomes the desired interpolated value. Since successive frames are displayed very rapidly, to the human eye the afterglow (or visual persistence) phenomenon causes the screen to appear as if an enlarged image is being displayed at all times without incongruity (i.e., the varying values of the interpolated pixels are not noticed by the human eye).

Abstract: Frame rate modulation is effected in which image data, which expresses a density of one dot by 4-bit dot data, is converted into a plurality of frame data, which express a density of one dot by 3 bits, so that the plurality of the frame data are sequentially displayed on the LCD. In the above conversion, the high order 3 bits of the dot data are extracted and made into data of one dot of each frame. In a case in which the least significant bit of the first dot data is 1 and the most significant bit is 0, 1 is added to a corresponding portion of the respective frame data. In a case in which the least significant bit of the dot data is 0 and the most significant bit is 1, 1 is subtracted from a corresponding portion of the respective frame data. In accordance with the above description, the image data is converted into the frame data as shown in Table 2, and the sum (apparent densities) of the plurality of converted frame data always changes in accordance with the changes in the dot data.

Abstract: A system for horizontal expansion of low resolution display modes onto high resolution displays including flat panels at a variable scaling factor is disclosed. The system may be combined with known methods for vertical expansion to allow low resolution display modes to be expanded onto any high resolution display. Two different methods are provided, one for graphics modes and one for text modes, to attain better screen image quality. In the first method, a first pixel data sequence to be expanded is first oversampled at a multiple of the frequency thereof to produce an intermediate oversampled data sequence. The oversampled data sequence is linearly decimated by a factor of less than unity to produce a replicated second data sequence longer than the first, which is then displayed.
