[Problems to be Solved by the Invention] Since the conventional screen display device is constructed as described above, when displaying a three-dimensional screen, it is necessary to use a projection diagram in which the Z coordinate is imaginary and the view point is indicated. Even though it may be displayed on a dimensional screen, it cannot actually be displayed on a three-dimensional screen, and furthermore, it is only possible to display a screen that combines multiplexed screen displays such as text screens and graphics screens on a single screen. There was a point.

[0005] This invention was made in order to solve the above-mentioned problems, and it is possible to display a three-dimensional screen as it is in three dimensions instead of displaying it in two dimensions, and it can also be displayed on a text screen or graphics screen. The object of the present invention is to obtain a screen display control method that can simultaneously display multiple screens on multiple screens.

[Means for Solving the Problems] A plurality of transmissive liquid crystal panel displays 1 according to the present invention are stacked in the Z-axis direction, and a screen of the transmissive liquid crystal panel display 1 is selected.
An X-coordinate multiplexer 5 for controlling the coordinates, and a Y-coordinate multiplexer for selecting the screen of the transmissive liquid crystal panel display 1 and controlling the Y-coordinate.
coordinate multiplexer 6 and the above-mentioned X coordinate multiplexer 5
and a screen control unit 4 for controlling the Y-coordinate multiplexer 6 to select each individual transmissive liquid crystal panel display 1 in the Z-axis direction to display a screen, and a multi-layered transmissive liquid crystal panel display. Control is performed so that only one selected screen is displayed.

[0007]

[Operation] A plurality of transmissive liquid crystal panel displays 1 are stacked in the Z-axis direction. The X-coordinate multiplexer 5 selects the screen of the transmissive liquid crystal panel display 1 and controls the X-coordinate. The Y coordinate multiplexer 6 selects the screen of the transmissive liquid crystal panel display 1 and controls the Y coordinate. The screen control unit 4 controls the X-coordinate multiplexer 5 and the Y-coordinate multiplexer 6 to select each transmission type liquid crystal panel display 1 in the Z-axis direction and display the screen. Therefore, only the selected screen of the multi-configured transmissive liquid crystal panel display 1 is displayed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic diagram of a screen display device employing a screen display method according to an embodiment of the present invention. In FIG. 1, 11 is a multi-structured liquid crystal panel display constructed by stacking a plurality of transmissive liquid crystal panel displays (hereinafter simply referred to as liquid crystal panel displays) 1, and 2 is an X of the screen of the liquid crystal panel display 1. 3 is an X coordinate electrode to which a voltage is applied to indicate the coordinate; 3 is a Y coordinate electrode to which a voltage is applied to indicate the Y coordinate of the screen of the liquid crystal panel display 1; An X-coordinate multiplexer 6 controls the coordinates, a Y-coordinate multiplexer 6 selects the screen of the liquid crystal panel display 1 and controls the Y-coordinate, and 4 controls the X-coordinate multiplexer 5 and the Y-coordinate multiplexer 6 to select individual liquid crystals in the Z-axis direction. A screen control unit for selecting the panel display 1 and displaying the screen; 2a is the X coordinate signal line to the X coordinate multiplexer 5; 2b is the X coordinate signal line from the X coordinate multiplexer 5;
Z coordinate signal line 3b is Y coordinate signal line from Y coordinate multiplexer 6
Z coordinate signal line, 3a is a Y coordinate signal line to the Y coordinate multiplexer 6, 4a is a Z coordinate signal line to the screen control unit 4, 4b
is a Z coordinate screen control signal line from the screen control section 4.

Next, the operation of this embodiment will be explained. Each liquid crystal panel display 1 operates in the conventional manner. First, a Z coordinate signal is given to the Z coordinate signal line 4a, and thereby the screen control section 4 gives a Z coordinate screen display control signal to the X coordinate multiplexer 5 and the Y coordinate multiplexer 6 via the Z coordinate screen control signal line 4b. . Further, an X-coordinate signal is applied to the X-coordinate multiplexer 5 from the X-coordinate signal line 2a, and a Y-coordinate signal is applied to the Y-coordinate multiplexer 6 from the Y-coordinate signal line 3a. Thereby, the X coordinate multiplexer 5 and the Y coordinate multiplexer 6 are controlled, and the XZ coordinate signal and the YZ coordinate signal are output to the XZ coordinate signal line 2b and the YZ coordinate signal line 3b. Therefore, each liquid crystal panel display 1 is
is selected and the screen is displayed.

[0010] At this time, the liquid crystal panel display displays a screen when the screen display is selected, but when the screen is not selected, it transmits light, and as a result, the entire multi-layered liquid crystal panel display Control is performed so that only the items selected for screen display are displayed on the screen. By displaying and multiplexing a two-dimensional screen on each liquid crystal panel display 1, it is possible to simultaneously display a three-dimensional graphics display, a text screen, and a graphics screen on other screens.

[0011] In the above embodiment, a case has been described in which only the transmissive liquid crystal panel displays are multiplexed, but a transmissive liquid crystal panel display and a cathode ray tube may be combined and multiplexed. In this case, the transmissive liquid crystal panel display is naturally placed in front of the cathode ray tube.

0012

As described above, according to the present invention, a plurality of displays including at least a transmissive liquid crystal panel display are stacked in the Z-axis direction, and the screen of the display is selected to control the X coordinate. a Y coordinate multiplexer that selects the display screen and controls the Y coordinate, and a Y coordinate multiplexer that controls the X coordinate multiplexer and Y coordinate multiplexer
Since the configuration includes a screen control unit for selecting individual displays in the axis direction and displaying the screen, a three-dimensional matrix in the X, Y, and Z coordinate directions is constructed, and by multiplexing the displays, multiple displays can be displayed. Screens can be displayed at the same time, and therefore three-dimensional screen display and multi-screen multiple display can be easily realized.For example, text screens and graphics screens can be displayed simultaneously on multiple screens, and the shading of each screen can be changed. By doing so, effects such as multicolor screen display can be obtained.
