Technical Background At stadiums, large color fRy boards are used as scoreboards, usually displaying text and displaying a color image along with or separately.This type of display board is red (R
), blue (B), and green (G) light bulbs are arranged in a matrix and are selectively turned on to display images or characters (including symbols) or patterns, but in order to express colors. A set of R, G, and B3 bulbs is 3.6.
Make it emit light at a ratio of 1. (Like that, R, G,
B) Adjust the amount of light emitted from each bulb.) In addition to the individual patterns of red, blue, and green, the R, G, and H bulb groups are lit individually, and the brightness of each color bulb is adjusted for intermediate colors.

Conventional technology and problems By the way, when displaying composite colors such as white or neutral colors, the unit is three light bulbs of R, G, and B.
, B In single color display, R, G, and B individual bulbs are the unit,
The pitch becomes rough. To explain this point using diagram @1, 1o
12 shows a set of R, G, and B light bulbs, which are units (picture elements) of a composite color. In this figure, the composite color unit consists of four light bulbs R', G, G, and H, but in principle, these are R, G, and B, with just one extra h and a. It is. Then, if one extra G is provided, as mentioned above, as a white unit, G=6, R=
3. Since there are 6 light bulbs with B = 1, you can use 3 light bulbs as G light bulbs (2 make 6 light bulbs).This is the same as R light bulbs, and you only need to use a low brightness one for B. (For example, G
= R = 300 foot lamberts, B = 1007 - lamberts). Moreover, by doing so, the number of scanning lines is doubled isometrically, and there is also the advantage that the resolution is increased. The pitch of the group of light bulbs is A, but the pitch of the composite color unit is B, which is twice that of A. Even when displaying in a single color of blue (B) or red (R), the pitch is B, and the pitch is green (G).
) is similar in the horizontal direction, but is B/2 in the vertical direction and is shifted in the horizontal direction.

The smaller the pitch of the picture elements, the more irregular patterns can be displayed, and therefore, the smaller the patterns can be displayed. This □.

Therefore, televisions have about 300,000 picture elements, but large color display panels for light bulbs have 3 to 3 pixels due to cost constraints.
We have kept it to 50,000 pieces. If the number of picture elements is small in this way, there is a restriction on the lower limit of display characters, and it is difficult to display characters that are too small.

発明の目的 本発明は絵素数従ってコストを増加することなく繊細、

Purpose of the Invention The present invention is designed to reduce the number of picture elements and thus reduce the cost without increasing the cost.
The idea is to make it possible to display small patterns.

The present invention was made based on the fact that the picture element pitch can be shortened to η/2ζ0.7 by tilting the display panel of FIG. 1 by 45 degrees and displaying a pattern in green (G).

Embodiment of the Invention FIG. 2 shows an embodiment of the invention, which is obtained by tilting the structure of FIG. 1 by 45 degrees. In this way, the pitch of green G in the horizontal and vertical directions is C = 115, assuming that the distance A between the R, G, and B bulbs remains unchanged.
A becomes smaller than B=2A.

また文字は緑1色による表示であるから、RGBによる
白色表示のように近距離では白色とならずに個々のR,
G、Bに見えるという問題もなく、視識性が向上する。
In addition, since the characters are displayed using only one color, green, they do not appear white at close range, unlike the white display using RGB, but the individual R,
There is no problem that it looks like G or B, and visibility is improved.

第1図従来例のB=2Aから2C=24Aに大になる。
However, the horizontal and vertical pitches of R, G, and B composite color units increase from B=2A in the conventional example shown in FIG. 1 to 2C=24A.

45斜め方向のピッチは2人で、従来例と同じである。45 The pitch in the diagonal direction is two people, which is the same as in the conventional example.

図形は一般に文字よ勺は繊細度が低く、方向は種々まち

Graphics, such as letters and symbols, are generally less sensitive and have different directions, so the composite color display is the same as before.

Make it BB. The above N is, for example, 4, which provides 16 types of brightness. The shift register 42 has n stages,
The number of bits in each stage is N, and the bits are shifted by the same clock as the sampling clock CLK.
When n luminance signals for one row of 0's are taken in sequentially, they are output in parallel and the same operation is repeated. The register 44 waits for a number of stages equal to the number of rows m of the matrix 40, each stage having one bit.
Data such as 1000...... is preset to these, which is shifted by the horizontal synchronizing signal H8,
The output line L (K1 to Lm
one of them) causes the driver of the row to read the contents of the register 42. Data is taken in by the drivers in order from the first row to the mth row, and each driver creates a pulse-width modulated output using the data it takes in, which turns on the light. A screen similar to the TV screen will be displayed on the display panel.

The output of is given to registers 42 and 44. Although the display characters are not shown, they are stored in the screen memory, read out line by line and input into the register 42, and when the input for one line is completed, the output from the register 44 is transferred to the drivers 11 to 1n.
The data of the next line is input to the register 42, and when the input is completed, the data is transferred to the next line of drivers (21 to 2n, not shown) by the output of the register 44, and this process is repeated thereafter. The shift procedure and the number of bits of the brightness signal are the same as in the case of image □ display, but the brightness control data is given only to the green light and not to the red and blue lights.

For example, if the luminance signal is 4 bits, the width modulation output is the output of each stage of the quaternary counter (as is well-known, if the period of the output to the 200th power is T, then 2 to the 1st power is 2T, and 2 to the 202nd power is 4T).
, 203rd power is 8T), turn them on and off with bit 1.0 of each digit of the 4-bit luminance signal, and take their logical sum.
