Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a display system, and particularly to a display system using plastic tubes.

(Prior Art) Conventionally, this type of display device using a cathode ray tube displays many character strings, mosaic figures, and graphs on the screen, and is often used in systems where the display contents are viewed closely. For display devices intended to be visible from a distance, there is a Mars screen, or a display consisting of a single dedicated board in which multiple display elements capable of displaying large characters are lined up. Methods such as changing the color of the panel to enable distant display were used.

These i have the disadvantage that a new dedicated board must be developed depending on the size of the display board, display contents, etc. (Objective of the Invention) The purpose of the present invention is to By eliminating such drawbacks of conventional devices and using a commonly used cathode ray tube display device as one display unit, a plurality of these devices can be arbitrarily arranged to display one character in a mosaic display on one display device screen. (Structure of the Invention) According to the present invention, brightness information is given to a raster scanned in the t-1-th order on a CRT screen. A CRT display that can display any color on the top and several small blocks (modules) that cover the CRT display screen.
It has a display device which is divided into two modules and controlled to arbitrarily give any color to this module, and by arbitrarily arranging this display device in a vertical grid, large characters can be displayed as a whole. A display device system is obtained, which is characterized in that it can be obtained.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a display screen used in one embodiment of the present invention. In Figure 1, display II! iI song 11 is a small block of 80 frames horizontally and 26 vertically on the CRT display screen (
module). 01 blocks (
The module is further composed of 9 dots horizontally and 16 dots vertically.

l! FIG. 2 shows a cathode ray tube display device that controls the CRT display screen shown in FIG. 381. In FIG. 2, each display device controls the display data memory 21 that stores screen display data in turns 1-07 and the display data memo 921.
The display control unit 22 and M! (e) Generates a display pattern based on the display data obtained from the display data memory)
a turn generation section 23, a refresh memory 24 for storing the display information (turns) from the pattern generation section 23;
(Indication) (includes a video signal generating section 25 that converts a turn into a video signal, and a CRT circuit 26 that obtains a dot signal from the video signal generating section 25 as a luminance signal.

In this cathode ray tube display device, the screen is subdivided into arbitrary blocks (modules), and a given pattern can be displayed in a mosaic form using the subdivided blocks.

No. 311g1 shows a display system capable of displaying from a distance, which is an embodiment of the present invention. In Fig. 183, this display device system can display a series of data as a whole by giving arbitrary display information to the display devices arranged vertically and horizontally. For example, it is displayed in "capital letters" and can be seen from a distance.

To explain the operation of Jin's embodiment, this CR1 display device provides luminance information to the raster that scans sequentially on the CB and T screens, making it possible to display any color on the CRTiiuli, and the screen display data is Display data memory 21
is stored in a 1-0 pattern. The 115 control section 22 reads out this 1-0 pattern, and the video signal generation section 23 generates a display pattern according to the read 1-0 pattern. This display pattern is stored in the refresh memory 24. Video from refresh memory 24 (6
The signal is given to the BT circuit as a luminance signal.

As a result, a mosaic display of arbitrary characters or figures is performed on the CRT screen. Note that this display device allows for easy color display by specifying the background color and font color.In this way, in one embodiment of Kisame Akira, multiple displays can be displayed as shown in Figure 3. By combining the parts, a series of information is displayed and output.

(Effects of the Invention) As explained above, the present invention uses a plurality of ordinary display devices to enable easy identification from a distance in the dark, and easy color display (diminishing the background color and text color). & Mouth that allows you to get the effect you want.
