摘要： When a specific signal (such as copy guard signal) is added between horizontal synchronizing signals in a composite synchronizing signal, and the addition period of the specific signal is defined in a specific period on the basis of the vertical synchronizing signal, the composite synchronizing signal is masked to remove the specific signal, thereby obtaining a masked composite synchronizing signal. Afterwards, from the masked composite synchronizing signal, the horizontal synchronizing signal and vertical synchronizing signal are obtained. In the case of composite synchronizing signal containing noise, without masking, the horizontal synchronizing signal and vertical synchronizing signal are directly obtained from the composite synchronizing signal. Therefore, when noise is not present, the horizontal synchronizing signal and vertical synchronizing signal may be obtained without disturbing the video image.
摘要翻译：当在复合同步信号中的水平同步信号之间添加特定信号（例如复制保护信号），并且基于垂直同步信号在特定周期内定义特定信号的相加周期时，复合同步信号被掩蔽以去除特定信号，从而获得掩蔽的复合同步信号。之后，从掩蔽的复合同步信号中获得水平同步信号和垂直同步信号。在包含噪声的复合同步信号的情况下，没有掩蔽，从复合同步信号直接获得水平同步信号和垂直同步信号。因此，当不存在噪声时，可以获得水平同步信号和垂直同步信号而不干扰视频图像。

摘要： A phase looped oscillating circuit includes a signal comparing device which can compare a plurality of different input signals with each other and emit a signal based on this comparison. The signal comparing device emits a control signal to a level converting device, a signal converting device is operatively connected to the level converting device. A signal from the converting device is received by an oscillating device and an oscillating signal is fed back to the signal comparing device via a divider. To compensate for fluctuation of an invertor in the signal converting device, the signal comparing device provides a fixed level signal stabilized at a 50% duty cycle. This stabilization also stabilizes electrical noises that may be present.

摘要： An improved row electrode driving circuit can drive a matrix type display apparatus without necessitating digital signals transmitted between partial row electrode driving circuits. Each of the partial row electrode driving circuits is allocated with a number. In each of the partial row electrode driving circuits, shift register shifts a pulse signal to sequentially output it from a plurality of outputs. At each time when a predetermined number of clock pulses have been counted, a count signal is produced. When the shift direction is set to the upper direction, a signal indicating the allocated number is produced. When the shift direction is set to the lower direction, a signal indicating a number which is obtained by subtracting the allocated number from a specified number is produced. When this number and the clock pulse count number satisfy a predetermined relationship, the pulse signal is output.

摘要： An improved column electrode driving circuit can drive a matrix type display apparatus without necessitating that digital signals be transmitted between partial column electrode driving circuits. Each of the partial column electrode driving circuits is allocated with a number. In each of the partial column electrode driving circuits, a shift register shifts a sample signal to sequentially output it from a plurality of outputs. At each time when a predetermined number of clock pulses have been counted, a count signal is produced. When the shift direction is set to the right direction, a signal indicating the allocated number is produced. When the shift direction is set to the left direction, a signal indicating a number, which is obtained by subtracting the allocated number from a specified number, is produced. When this number and the clock pulse count number satisfy a predetermined relationship, the sample signal is output.

摘要： A liquid crystal display panel is so constructed that a plurality of pixels are arranged in a matrix form having the number of lines twice that of horizontal scanning lines for one field of interlaced scanning video signals obtained by scanning an original image every other line, the arrangement of the pixels being shifted horizontally by one-half of a pixel between adjacent upper and lower lines. A row driving circuit applies, to the pixels in the upper line of the two adjacent upper and lower lines, data voltages obtained by sampling a video signal representing one horizontal scanning line by a clock signal of the timing that matches the number of pixels in the upper line and the arrangement of the pixels, and applies, to the pixels in the lower line, data voltages obtained by sampling the above video signal representing one horizontal scanning line by a clock signal of the timing shifted by 1/2 cycle from the above clock signal. Thus, one horizontal scanning line represented by the video signal is displayed using the two upper and lower lines of pixels, thereby enhancing the display quality of the produced image.
