C8 is related to the color character display device VC, which has been designed to be fully defined.

Conventionally, this kind of character nice play type color letters Omotesui made gvc letters (alphabetic).

When displaying numbers, characters such as katakana, etc. 1 For example] t5! Based on the display control information that waits for the Lrr format shown in J, the display is in line rx. In the display control information 1 shown in Figure 1 of Jin, the ninth character code (for example, 8-bit A3Cl
・I code) 2 or the first byte to be set 3 and 1 Color code to specify the color of the character to be displayed (for example, 3
There is a binary code of bits) such as 4, t, and the second byte 5, which consists of ff-j. Then, the color character display device rr converts the character code 2 in this display control information IK into a dot signal using a character generator, etc., determines the color of the character from the color code 4, and based on this result, one display screen is displayed. Characters are displayed at predetermined locations using the dot matrix shown in FIG.

Fig. 2 shows an example of display when IIIJ character code 2 indicates rAJ of alpha vent.rc
Thing T, this combination, among the 8 x 8 dots shown in the same figure, the dot in the diagonal 1M corresponding to the character "AJrc" is colored in the color specified by the color code 4, and this diagonal line is removed. Since the dots in the background of each dotted letter "A" have no color development, they have the same color as the displayed fabric. Tomo former = conventional (1) ft5 - h to character display device
σ1 Normally, front color light color code K can be arbitrarily selected with one color code, but only the fabric color for punk color σ display 0iii can be selected, so the color combination of text and background can be freely selected. Then, for example, I couldn't make a frame like LurrC to make the letters float from the background η.

A reversal bit 6v is provided to reverse the coloring relationship between the dots and the color development': ') F(: Dot matrix σ shown in Figure 3).

The character "A" is displayed using this inversion bit 6 to indicate the jittered state τ', as shown in this figure, in this case)
The front color is the color of the fabric on the display screen, and the back color or the color hood is the specified color. Once upon a time, this σ)L color character display device IjvcLt'
L is for the background frame to be colored with any color, or r'' to dance.
In view of the above circumstances, the characters that should be displayed on the front are extremely difficult to see due to the color of the fabric on the display screen and the color of the rx, and the characters still stand out from the background. To provide a color character display device that solves the above-mentioned problems by arbitrarily setting a front color, which is the color of one character, and a back color, which is the color of the background part of one character. In addition to the character code, the front color code and the back color code must be stored separately.
Against C.

There is a VC model in which the (corresponding to the character to be displayed) ant color code and back color code are selectively supplied to the dot signal corresponding to the Φ Yaracta code of the character to be displayed. Hereinafter, one embodiment of invention C will be described in detail with reference to the drawings.

XThe dot indicated by diagonal lines in one of the RIs in the first row in FIG. 2 is red, and the other dots are white VC. From then on.

Each dot in the 2nd row R2, 3rd row R, ... 8th row R, moves in the same manner as described above, and each dot is colored individually, and as a whole, the front color is applied to the RC receiver in Figure 2. You can see the letters rAJ which are red, pack color or white. It should be noted that the display of other dot matrices on the VC on the shallow water screen is also performed in accordance with exactly the same operation as described above.

1. In the above-mentioned character rAJO table, when the inversion pit 6 in the display control information 1 vc is 1, the dot signal output from the shift register 17 is 1.
Since VCrr corresponds to the color specified by the pack color code 7, 0 of the same dot signal, or the color specified by the front color code 4, the letters rA-lrr, the third
Fvt HdLsrc-s=is done. (In this case, the dots with the diagonal line are colored red and the other dots are colored white, so one character rAJrt can be displayed as the front color or white, and the pack color as red.

From the above explanation, it is clear that the color character display device KL according to the present invention has a character code memory, a front color code memory, a pack color code memory, a display system aS, a dot signal generator, a selector and a display unit. 8ff each, 1 unit to store the character code, front color code, and back color code.
When displaying characters, the front color code and back color code corresponding to each character should be displayed once per display section, based on the dot signal output from the dot signal generator.
