A display device consisting of a matrix 2 of display elements is in this case shown in FIG. The system shown in Figure 10 incorporates a block diagram representing two circuits. can be controlled. A clock signal 202 along with the appropriate digital signal is provided via line 201. The splay data pulses are placed into an 8-hint shift register 200. Schiff The register 200 is connected to the transistor array 204 through a transistor array 204. , drives the display device 250.

Two display elements 250 are coupled to an 8-bit shift register, and the overall A series of registers is used for the display device, each one receiving a clock signal 2. Data pulses are provided via lines 028 and 201. display data is , one of the bit sets is the selected NPN) transistor (83, 94, 85 or 86) No. 121 R59-501380 (6) Conveniently, it is in binary format so that it can be easily accessed. Line 81 is effective is energized whenever a display element is to be set, as shown in Figure 11. The period is a strobe that remains energized.

The pulse system used to operate each display device is shown in Figures 11a-d. is shown. FIG. 11a shows the Darlington 2000 being arranged so as to present a red surface 54 for viewing. Pulses that need to be applied to terminals 110, 111, +12, 113 of the array Show the system. Similarly, FIG. 11 S concerns the green surface 57, and FIG. 11d relates to the white surface 55.

In this embodiment, the viewed surface and the follower's N if that surface is viewed. The following rA coefficients apply with respect to the pole pieces on which the poles are placed:

Poetry that should present the red side for viewing (by 180 degree rotation), appropriate display A data pulse is placed in register 200 and the pulse system shown in FIG. Given. During a first time interval T1, applied to terminals 110 and 111 The pulse turns on transistor θ3.85 and terminals 100 and 101 are grounded. It will be done. The coils 71a and 73b are energized to generate a north pole at the top of the pole piece 75. At the same time, an S pole is generated at the top of the pole piece 77. The magnetic follower 62 placed on pole piece 75 (so its south pole is placed on pole piece 77) , the magnetic funnel lower 62 is repelled and slides up the shaft 59, and the magnetism is released from the protrusions 63 to 66. The end of the air lower 62 is freed so that the cube 50 rotates counterclockwise. , Fj&Ki follower 62 places its south pole on the pole piece 78 and its north pole on the pole piece 78. and stand still.

During the second time interval T, the terminal 100 remains grounded and therefore the pole piece 7 5.77 remain as the north and south poles, respectively. Terminals 111, 112 Terminals 100 and 102 are no longer grounded because no pulse is applied to them. . However, a pulse is applied to terminal 113 and therefore terminal IQ3 is grounded. . By energizing coil 72c+, an S pole is generated in pole piece 76, and coil 74 is energized. By applying force, a north pole is created in the pole piece 78. And the magnetic follower 62 is shown in FIG. The counterclockwise rotation 62 then places its north pole on the pole piece 77 and rotates the pole piece 75.77. be pulled upwards. (Thus, the foyer is rotated 80 degrees by T, T2) When T2 is completed, the pulse ends and all coils 4 is deenergized, so the pole piece no longer has an induced appearance. However, the magnetic follower 62 is held between the protrusions 63 to 6B, so the cube 50 cannot rotate. stomach.

Assuming that the bright colored surface is to be removed, the pulse system shown in Figure 11 is utilized. death Therefore, a pulse is applied to terminals 110 and 113, and terminals 100 and 103 are grounded. will be missed. coil? Ia, 73b,? 2b and 74a are energized, and the pole piece 75 is energized. A north pole is generated, a south pole is generated at the pole piece 77, a south pole is generated at the pole piece 76, A north pole is generated in the pole piece 78 . At the end of the movement resulting from the pulse of Figure 11a, It will be recalled that the north pole of magnetic follower ~62 was on pole piece 77. The pole piece 7 Since 7 is now the S pole, there is no repulsion and the magnetic follower 62 remains at the predetermined value for the period T1. Remains locked in position.

During a second time interval T2, the pulse is maintained at terminal 113 and the pulse is maintained at terminal 1 12, terminals 102, 103 cuffs"rel. Coils 72b, 7 4a7; it remains energized, with the south pole at pole piece 76 and the south pole at pole piece 78; The N pole remains as before. Coils 71b and 73a are energized, and pole pieces 75 and 77 The polarities are reversed, giving pole piece 77 a north pole and pole piece 75 a south pole. ( The N end of the a1 follower 62, which is now on the N pole of the pole piece 77, is repelled, The follower slides up the shaft 58, at which point the follower's north pole touches the pole piece 76. Rotate counterclockwise until it is at the top of the S pole.

The operation of the pulse sequence shown in FIG. 11C1d is as described above with respect to FIG. 11C1d. It follows the same lines as above and therefore does not require a detailed explanation. death However, the constant pulse at terminal 112 of FIG. Between T1 and 72, a N pole is generated at the pole piece 77 and an S pole is generated at the pole piece 75, so that the magnetic The air follower 62 ends up in the desired alignment with its north pole on the pole piece 75. T A short pulse at terminal 113 during 1 and at terminal Ill during T2 causes pole piece 78 to ．． 76 is set up, then it is reversed and either T1 or T2 In this way it is ensured that the carrier is moved to its desired position. (90 degree rotation) Similarly, the pulse sequence shown in the first id is T1. Pole piece 76 for T2 , so that the magnetic follower 62 places its north pole on the pole piece 76. Form an array of key points. A short at terminal 112 between TI or at terminal 110 between T2? A moving pulse forms a moving magnetic field as before. (rotated 90 degrees) The design and configuration of display elements, their modes of operation, and the multicolor display itself. Various changes can be made to the details of the mode of operation. For example, pyfi The winding coil can be replaced by two regular coils driven by a bipolar circuit. Wear. In this way, we use a unidirectional current passing through coils wound in opposite directions. By reversing the direction of the current, the desired and opposite magnetization of the pole piece can be achieved without achieved. In such an arrangement, the pulse system may remain as before.

The relative placement of the coil and follower may be changed as desired. In the first example , the follower was placed vertically and surrounded by horizontal pole pieces. In the second example, The pole piece was vertical and the follower was placed above the pole piece in the hydraulic position. really effective In this sense, the pole pieces are placed in different planes and the follower is placed between them. Change In this case, rather than placing the base point only at one end of the pole piece, as in the two previous embodiments, It is best to place it at each end of the pole piece to be stripped.

In both embodiments, the reference point at which the pole pattern is defined is the end of the straight pole piece. However, it does not have to be. For example, if you omit the pole pieces altogether, you can - may be left to be influenced by the magnetic field of the coil. In another improvement, the pole pieces are carp The end pole piece is held in the cell in a straight line and at an angle with the pole piece. This eliminates the need for the follower to be aligned with the axis of the coil.
