Abstract
Display system and method for visually displaying arithmetic equations in a non-right justified manner. A first set of one or more arrays displays a first operand, a second set displays a second operand, and a third set displays a numeral. The numeral typically represents an answer to the equation. The display of at least one of the first operand, the second operand, or the numeral can be non-right justified. When non-right justification occurs, the array set corresponding to the non-right justified operand or numeral includes at least one more array than is required to display the operand or numeral, and at least one array to the right of that operand or numeral is left inactive.
Claims34
A method of visually representing arithmetic equations on a display, one at a time, each of the equations comprising (a) a left operand comprising at least one digit, (b) an arithmetic operator located to the right of the left operand and selected from the group consisting of an addition symbol, a subtraction symbol, a multiplication symbol, and a division symbol, (c) a right operand located to the right of the operator and comprising at least one digit, (d) an equal symbol located to the right of the right operand, and (e) a numeral located to the right of the equal symbol, said numeral comprising at least one digit and representing a member of a set consisting of a sum, a difference, a product, and a quotient, said left operand, said right operand, and said numeral each constituting a term of an equation to be displayed, the method comprising:
- simultaneously displaying at least one digit of the left operand in a first set of separate arrays, at least one digit of the right operand in a second set of separate arrays, and at least one digit of the numeral in a third set of separate arrays, each of said arrays being located in a separate fixed position on the display essentially horizontally to the left or right of each other array and comprising at least seven electronically operable segments, each segment being visually continuous, at least two of the segments for each array being elongate and oriented in substantially different directions, each of the sets of arrays having at least one array and at least one of the sets of arrays including at least two arrays so as to display at least two digits side by side;
- for at least a first equation, displaying a rightmost digit of one of the terms in one of the arrays, which array is used for a different, second equation to display a second-to-rightmost digit of the corresponding term of the second equation, said corresponding term in the second equation comprising at least one more digit than the corresponding term in the first equation.

A method of visually representing an arithmetic equation on a display, said equation having (a) a left operand comprising at least one digit, (b) an arithmetic operator located to the right of the left operand and selected from the group consisting of an addition symbol, a subtraction symbol, a multiplication symbol, and a division symbol, (c) a right operand located to the right of the operator and comprising at least one digit, (d) an equal symbol located to the right of the right operand, and (e) a numeral located to the right of the equal symbol, said numeral comprising at least one digit and representing a member of a set consisting of a sum, a difference, a product, and a quotient, said left operand, said right operand, and said numeral each constituting a term of the equation to be displayed, the method comprising:
- displaying the left operand in a first set of separate arrays, said first set of separate arrays having at least one array;
- displaying the right operand in a second set of separate arrays, said second set of separate arrays having at least one array;
- displaying the numeral in a third set of separate arrays, said third set of separate arrays having at least two arrays capable of displaying two digits side-by-side;
- each or said arrays being located in a separate fixed position on the display essentially horizontally to the left or right of each other array and comprising at least seven electronically operable segments, each segment being visually continuous, at least two of the segments for each of said arrays being elongate and oriented in substantially different directions;
- wherein at least one of the left operand, the right operand, or the numeral contains fewer digits than the number of such arrays in the corresponding array set, the rightmost array in said corresponding array set being inactive during display of the equation.

A method of visually representing an arithmetic equation on a display, said equation having (a) a left operand comprising at least one digit, (b) an arithmetic operator located to the right of the left operand and selected from the group consisting of an addition symbol, a subtraction symbol, a multiplication symbol, and a division symbol, (c) a right operand located to the right of the operator and comprising at least one digit, (d) an equal symbol located to the right of the right operand, and (e) a numeral located to the right of the equal symbol, said numeral comprising at least one digit and representing a member of a set consisting of a sum, a difference, a product, and a quotient, said left operand, said right operand, and said numeral each constituting a term of the equation to be displayed, the method comprising:
- displaying the left operand in a first set of separate arrays, said first set of separate arrays having at least one array;
- displaying the right operand in a second set of separate arrays, said second set of separate arrays having at least one array;
- displaying the numeral in a third set of separate arrays, said third set of separate arrays having at least two arrays capable of displaying two digits side-by-side;
- each of said arrays being located in a separate fixed position on the display essentially horizontally to the left or right of each other array and comprising at least seven electronically operable segments, each segment being visually continuous, at least two of the segments for each of said arrays being elongate and oriented in substantially different directions;
- wherein at least one of the terms of the equation is displayed non-right justified.

A display system for visually representing an arithmetic equation, said equation having (a) a left operand comprising at least one digit, (b) an arithmetic operator located to the right of the left operand and selected from the group consisting of an addition symbol, a subtraction symbol, a multiplication symbol, and a division symbol, (c) a right operand located to the right of the operator and comprising at least one digit, (d) an equal symbol located to the right of the right operand, and (e) a numeral located to the right of the equal symbol, said numeral comprising at least one digit and representing a member of a set consisting of a sum, a difference, a product, and a quotient, said left operand, said right operand, and said numeral each constituting a term of the equation to be displayed, said display system comprising:
- a first set of separate arrays capable of displaying the left operand, said first set of separate arrays having at least one array;
- a second set of separate arrays capable of displaying the right operand, said second set of separate arrays having at least one array;
- a third set of separate arrays capable of displaying the numeral, said third set of separate arrays having at least two arrays capable of displaying two digits side-by-side;
- each array being located in a separate fixed position on the display system essentially horizontally to the left or right of each other array and comprising at least seven electronically operable segments, each segment being visually continuous, at least two of the segments for each array being elongate and oriented in substantially different directions;
- an electronic control system which causes the non-right justified display of at least one of the terms of the equation, whereby the arithmetic operator, the equal symbol, and all the digits of said equation appear better visually-balanced to a human observer.
