Description

[Detailed description of the invention] The present invention has a pattern display device, for example, a dot-shaped segment electrode and a common electrode facing the segment electrode, one in the center and the other six in point symmetry with respect to the segment electrode. This invention relates to display devices such as liquid crystals that display dice patterns in an array, and in particular to pattern display devices that reduce the number of control signals and drive circuits supplied to these devices by improving the connection conditions of common connections and segment connections. It is.

Hereinafter, one embodiment will be described in detail based on the drawings.

FIG. 1 is a diagram showing a dice display pattern in the pattern display device of the present invention, and FIG. 2 is a diagram showing the connection state of segment electrodes and common electrodes of the same display device.

This pattern display device performs dice display by a combination of seven display segment electrodes A to G formed in a dot shape, for example, a circle, and one display segment electrode H surrounding them.

Further, common electrodes A' to H' having substantially the same shape as the display segment electrodes A to H are arranged opposite to each other, and in particular, segments and common electrodes (A<A'>~G<
G'>) has an electrode (D<D'>) arranged in the center, and the other six electrodes are arranged point-symmetrically as shown in the figure.

The connection of the segment electrodes is as shown in Figure 2a.
The electrodes A, B, F, and G are commonly connected to supply the segment signal Sa, the electrode D is supplied with the segment signal Sb, and the electrodes C, E, and H are commonly connected to supply the segment signal Sc. .

On the other hand, as shown in b, the common electrodes are electrodes A′,
Connect G′ and H′ in common to supply common signal H ₁ ,
It is assumed that electrodes B', C', D', E', and F' are commonly connected to supply a common signal _H2 .

When displaying dice using a pattern display device with segment wiring and common wiring as described above, drive signals for controlling each display are expressed by the following equations. (Note that the segment electrode H is always displayed.) That is, when displaying "1" of the dice, it is displayed by the combination shown in equation (1).

Sb・H ₂ +Sc・H ₁ ...(1) When displaying "2" signals, they are displayed by the combination of signals shown in the second equation.

Sa・H ₁ +Sc・H ₁ ...(2) When displaying "3", it is displayed by the combination of signals shown in the third equation.

Sa・H ₁ +Sb・H ₂ +Sc・H ₁ ...(3) When displaying "4", it is displayed by the combination of signals shown in the fourth equation.

Sa・H ₁ +Sc・H ₂ +Sc・H ₁ ...(4) When displaying "5", it is displayed by the combination of signals shown in the fifth equation.

Sa・H ₁ +Sc・H ₂ +Sb・H ₂ +Sc・H ₁ ...(5) When displaying "6", it is displayed by the combination of signals shown in the sixth formula.

Sa・H ₁ +Sc・H ₂ +Sa・H ₂ +Sc・H ₁ ...(6) The pattern displayed by the above formula is as shown in Figure 3, and when displaying the die roll "1", Segment electrodes D, H, segment electrodes A, G, H when displaying "2", segment electrodes A, D, G, H when displaying "3", segment electrodes when displaying "4" A, C, E, G,
H, when displaying "5", segment electrode A,
When displaying C, D, E, G, H, and "6", segment electrodes A, B, C, E, F, G, and H are driven, respectively.

In this way, in this embodiment, the segment electrodes and the common electrodes are effectively connected in common, so that
Dice display can be achieved with three types of segment signals and two types of common signals, and there is an advantage that the number of control signals normally required for each electrode and the number of drive circuits for outputting the signals can be significantly reduced.

FIG. 4 is a block diagram of a display drive control circuit for a game device (eg, a game calculator, a game watch) equipped with this pattern display device.

In the configuration, the display information stored in the display register 1 is sequentially read out and given to the display decoder 2, and is also stored again in the display register 1. The display decoder 2 decodes display information (numeric information and information necessary for dice display) given from the display register 1 and supplies it to the drive circuit 3. If the display information is a dice display symbol, this drive circuit 3 derives segment signals Sa to Sc and common signals H ₁ and H ₂ and drives the dice display liquid crystal shown in FIG. 1 (or FIG. 2) above. It is given to the pattern display section 4. The liquid crystal pattern display section 4 includes, for example, a plurality of dice display sections, and is configured so that a random dice display can be simultaneously obtained by combining a segment signal and a common signal for each display section.

On the other hand, if the display information is numerical information, the drive circuit 3 outputs the segment signals S1 to _S1 according to the numerical information.
S ₄₅ is derived and applied to the Japanese character-shaped liquid crystal display device 5, and common signals H ₁ and H ₂ similar to those of the dice display section 4 are applied to the liquid crystal display device 5.
This "Japanese"-shaped liquid crystal display device 5 includes, for example, a multi-digit "Japanese"-shaped segment display section and a segment display section for displaying other fixed patterns.

As described above, when displaying dice using a pattern display device consisting of a plurality of dot-shaped segments arranged appropriately, the present invention improves the number of connections between the segment electrodes and the common electrode by improving the connections between the segment electrodes and the common electrode. Therefore, the number of display control signals and drive circuits can be significantly reduced, and the circuit configuration of the display drive control circuit can be simplified.
