摘要： PURPOSE:To surely separate a horizontal synchronizing signal from a composite signal by supplying an edge signal to a horizontal synchronizing signal reproducing circuit, inhibiting the operation of an FF circuit for a prescribed time from the rear edge of the composite synchronizing signal to output a reproduced horizontal synchronizing signal. CONSTITUTION:The edge signal from an edge detection circuit 2 detecting the front edge and the rear edge of the composite synchronizing signal is fed to the horizontal synchronizing signal reproducing circuit 3. Then the operation of the FF circuit 3a is inhibited for a prescribed time selected in response to the relative position of horizontal and vertical synchronizing signals shorter than a time obtained by subtracting the pulse width from the period of the horizontal synchronizing signal from the rear edge of the composite synchronizing signal by the inhibition signal generating circuit 4 and the reproduced horizontal synchronizing signal separated from the composite synchronizing signal is outputted from the horizontal synchronizing signal reproducing circuit 3.

摘要： PURPOSE:To reduce the power consumption by controlling the display volume so that the increase of display volume is suppressed based on the detection output of a display volume detecting means. CONSTITUTION:The display volume of display data displayed on a plasma display panel 1 is finely detected by a display volume detecting means 37. The display volume of the plasma display panel 1, namely, the discharge time of a cell in the discharge state is finely controlled based on the detected display volume by a display volume control means 38. Consequently, the power consumption for the number of cells in the display state is gently changed. Thus, the power consumption is reduced without damaging the visual recognizability of display.

摘要： PURPOSE:To display an image plane consisting of an optional number of lines than the number of display liens of a display device at an optional vertical position on a display panel at all times by providing a means which generates a signal for varying and setting the number of blank feeding shift clock pulses, feeding lines with the blank feeding shift clock, and making no display in the blank feeding period. CONSTITUTION:A generation part 60 for a horizontal synchronizing signal as an interface signal to a matrix display device consists of a generating circuit 61 for the blank feeding shift clock, a generating circuit 62 for pulses of frequency which is an (n) times as high as a horizontal synchronizing signal, and a kick circuit 63 for the generating circuit 61. In this case, lines are fed on the display device by as many as the blank feeding shift clock pulses in the blank feeding period and no display is made throughout the period. For the purpose, this blank feeding period is so set that when the number of lines on the image plane is smaller than that of the display panel, parts of unnecessary lines at the upper and lower part of the display panel are fed in blank, thereby displaying the image plane in the center. Further, the image plane can easily be displayed at an optical desired vertical position.

Here, the control signal generating circuit 50 receives the display data and generates such a light emission control signal that the relation between the display level and the brightness that human senses based upon the light emission at the light emission point of the self-luminous type display device is nearly linear. Consequently, the variation in the quantity of light emission at the light emission point of the self-luminous type display device with the display level when the display level of the display data is high is easily confirmed.
