Abstract

PURPOSE:To read display contents on the screen of a display device easily by shifting the position of the display contents up and down, or left and right according to up and down or left and right vibration of the display device. CONSTITUTION:When the display 7 moves up owing to vibration, the fixed contact 2 and movable contact 5 of a detector 11 are connected together and a display position control signal generating circuit 12 sends a scroll-down signal for moving the display position down on the screen to a display control circuit 14, so that the display contents on the display 7 shift in position down on the screen. Namely, the display 7 shifts in position, the display control circuit 14 moves the display position of the display contents on the display 7 in the direction opposite to the movement direction of the display 7, so there is no displacement of the display position for a reader, so that the display is read easily and accurately.

Description

[Detailed Description of the Invention] This invention is a CRT installed in a place where vibrations occur such as in a car.
The present invention relates to a display control method for display devices such as the above.

Conventionally, as shown in Figure 1, the display method for displays such as CRTs in places where there is vibration, such as in automobiles, is such that the display indicated by the solid line frame in Figure 1 (1) may be damaged due to vibrations, etc. When you move up as shown by the dashed line frame, the display position of the display content also moves up together with the display, so the reader's eyes see double images as shown in Figure (C), and the display The content was difficult to decipher.

This invention was made in view of the above-mentioned points, and it is possible to change the display position of the display content on the display screen to the display when the display is displaced due to the vibration in a place where there is vibration such as in a car. Display control that corrects the display position of the displayed content on the screen to the reader by displacing (scrolling) it in the opposite direction to the displacement direction of the screen, thereby eliminating the difficulty in reading the displayed content. It provides a method. The present invention will be explained below based on the drawings.

FIG. 2 is a diagram showing display contents on a display screen for explaining a display control method showing an embodiment of the present invention. When the display indicated by the solid line frame shown in Figure Ca) moves to the position indicated by the broken line frame in Figure 2B, the display position of the display contents on the display screen is moved downward within the display screen. By moving the display and suppressing the displacement of the display position of the displayed content, as shown in Figure (C), even if the display moves, the display is corrected as if the display position of the displayed content had not shifted to the reader. Easy to read. Conversely, when the display moves downward, although not shown, the displacement of the displayed content is corrected by moving the display position of the displayed content upward within the screen. In the end, by displacing the display position of the displayed content on the screen vertically or horizontally in response to the vertical or horizontal vibration of the display,
Displacement of the displayed content is suppressed for the reader, making it easier to read the displayed content.

FIG. 3 is a diagram showing an example of a detector that detects the moving direction of the display. In the figure, 1 and 2 are fixed contacts, and a movable contact 5 is provided between the fixed contacts 1 and 2 with an insulator 3.4 interposed therebetween, and a weight 6 is attached to the tip of the movable contact 5. ing.

These fixed contacts 1.2, insulators 3.4, and movable contacts 5 constitute a switch mechanism. Further, FIG. 2A shows a static state in which no vibration is applied to the display, and both the fixed contact 1 and the movable contact 5 and the fixed contact 2 and the movable contact 5 are open.

FIG. 6B shows a state in which the display 7 has moved upward, the movable contact 5 is deflected by the inertia of the weight 6, and the fixed contact 2 and the movable contact 5 are closed. That is, in this switch mechanism, when the display 7 moves upward, the fixed contacts 2. When the movable contact 5 turns ON and moves downward, the fixed contact 1. This is an acceleration sensitive switch in which the movable contact 5 is turned on.

FIG. 4 is a block diagram of a display control system as an embodiment of the present invention. In the drawing, reference numeral 11 denotes a detector, and a display device comprising an acceleration sensitive switch shown in FIG. 3 and capable of displaying a risk roll. When the display 7 mechanically coupled to the display 7 moves upward due to vibration, the fixed contact 2 and the movable contact 5 of the detector 11 mechanically coupled thereto are turned ON, and a display position control signal is generated. A downward scroll signal for moving the display position downward on the screen is sent from the circuit 12 to the display control circuit 14, and the display position of the display contents on the display 7 is moved downward on the screen. Similarly, when the display 7 moves downward, the fixed contact 1 and the movable contact 5 are turned ON.
An up scroll signal for moving the display position upward is sent from the display position control signal generation circuit 13 to the display control circuit 14, and the display position of the display content on the display 7 is moved upward on the screen. In other words, when the position of the display 7 changes, the display control circuit 14 moves the display position of the display contents in the direction opposite to the moving direction of the display 7, so that the display position is changed for the reader. This means that there is no displacement, and the display can be read easily and accurately.

Although the above description is about correcting the display position of the display content in response to vertical movement of the display 7, it is clear that the display position can also be corrected in the same manner for vibrations in the left and right directions. Furthermore, by combining the vertical correction and the horizontal correction, it is possible to perform vibration correction of the display position of one display content with respect to the vertical and horizontal vibration numbers.

In the above embodiment, the detector 11 is an acceleration sensitive switch as shown in FIG. By using a potentiometer consisting of a power source 22, etc., to detect the direction of vibration, nine periods of amplitude, etc., and more appropriately control the direction, movement amount, speed, etc. of the display position of the displayed content, the correction can be made. It is also possible to increase the accuracy of

As explained in detail above, the display control method according to the present invention includes a display device such as a CRT, a display control circuit that moves the display position of display contents on the screen of the display device, and a display control circuit that moves the display content due to vibration or the like of the display device. If the display moves due to vibration etc., the detector detects the movement and moves the display position of the display content on the display screen in the opposite direction to the direction of movement of the display. Therefore, even if the display is displaced due to vibrations, etc., the display position of the displayed content remains unchanged for the reader, eliminating the difficulty of reading and making it possible to read accurately and easily. It has an extremely excellent effect of being able to do the following.
