示コントロール回路、αＤはＣＲＴ表示器である。(Prior art) Currently, the horizontal scanning frequency of display devices for personal computers is 1
5kHz, 8.311Hz, and 33kHz, the higher the frequency, the higher the frequency, and the current situation is that the frequency differs depending on the type of device or manufacturer, and the need for display devices that can be compatible with various types of devices is increasing. There is. In response to this demand, there is a display device whose system diagram is shown in FIG. This involves detecting only the required video signal from the video input signal (1) using the frequency detection circuit (2), and converting it to, for example, 15 to 17K.
Hz is divided into modes such as 22 to 26 kHz, 29 to 34 kHz, etc., and display modes (different types from display parameters such as scanning frequency 2 display position) are displayed for each mode, so the number of display modes increases. The frequency detection circuit becomes more complicated, especially when the horizontal and vertical frequencies are the same but the display positions are different. For this reason, adjustment is performed manually using a variable resistor (b) for horizontal and vertical synchronization adjustment, which is generally provided on the front surface of the display device. However, at present, such an operation section does not have an interface for selecting a video signal. Furthermore, changing the display mode has the undesirable drawback of changing the video signal as a result of changing the display mode.
In the figure, (3) is the selected video signal, (4) is the horizontal synchronization circuit constant, (5) is the vertical synchronization circuit constant, (6) is the horizontal position circuit constant, (7) is the vertical circuit constant, (8) is a brightness circuit constant, '(9) is a focus circuit constant, Ql is a display control circuit, and αD is a CRT display.

In some display modes (when the horizontal and vertical synchronization signals are the same but the display position is different), it was necessary to readjust the adjustment volume. However, in the present invention, the operation section has selections for each display mode, and the control section has a display parameter constant circuit corresponding to the selected video input signal, thereby eliminating the need to operate the adjustment volume for each display mode.

果は極めて大である。That is, according to the present invention, a circuit preset for each display mode, that is, a display parameter constant circuit specific to the display mode, is provided in the control section (2), and this is selected by a selection control signal sent from the operation section (2). is sent to the display unit (3) together with the selected required video signal and displayed. In this way, changing the display mode is done separately in the control unit, rather than simultaneously selecting the video signal on the display as in the past, so it is possible to avoid negative effects on the video signal as in the past. The display parameter constant circuit can be switched using only a control signal without the need for a complicated frequency detection circuit, making the circuit extremely simple. Therefore, it is particularly effective when there are many different display modes, and the effect is extremely high. It's large.
