Abstract
Abstract A display device for visually representing selected characters in dot patterns includes a circuit for determining the number of characters to be visually represented and a circuit for outputting, in response to the result of the determination, a dot pattern signal of a size rendered relatively greater in accordance with a reduction in the number of such characters. Since the displayed character size is enlarged as the number of the characters is reduced, the visual representation can be easily seen on the display screen.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
201 words
A display device for displaying characters in a form of dot patterns comprising: input means for inputting characters one at a time; display means for displaying a dot pattern corresponding to each inputted character as each character is inputted; count means for counting a number of characters inputted and for generating a count after the input of each character; and character generating means, operatively connected to said count means and said input means, for generating the dot pattern to be displayed according to each inputted character; said character generating means generating and re-generating dot patterns having distinct sizes such that the size of the dot pattern for displaying a first character is larger than the size of the dot pattern for displaying said first character and a second character and the size of the dot pattern for displaying said first and second characters and a third character is smaller than a dot pattern for displaying said first and second characters; said display means displaying and re-displaying said dot patterns having said distinct sizes; said character generating means reducing the size of the dot pattern in response to the inputting of each character until a predetermined number of characters have been inputted.
Claim 2
Dependent Claim
201 words
A display device for displaying characters in a form of dot patterns comprising: input means for inputting characters one at a time; display means for displaying a dot pattern corresponding to each inputted character as each character is inputted; count means for counting a number of characters inputted and for generating a count after the input of each character; and character generating means, operatively connected to said count means and said input means, for generating the dot pattern to be displayed according to each inputted character; said character generating means generating and re-generating dot patterns having distinct sizes such that the size of the dot pattern for displaying a first character is larger than the size of the dot pattern for displaying said first character and a second character and the size of the dot pattern for displaying said first and second characters and a third character is smaller than a dot pattern for displaying said first and second characters; said display means displaying and re-displaying said dot patterns having said distinct sizes; said character generating means reducing the size of the dot pattern in response to the inputting of each character until a predetermined number of characters have been inputted.
Claim 3
Dependent Claim

The apparatus of claim 1, wherein the display device is part of an on-vehicle information system.
Claim 4
Dependent Claim
14 words
The apparatus of claim 1, wherein the display device is part of a telephone.
Claim 5
Dependent Claim
15 words
The display apparatus of claim 1 wherein the display device is part of a calculator.
Claim 6

Claim 7
Independent Claim
185 words
A method for displaying characters in a form of dot patterns comprising the steps of: (a) inputting characters one at a time; (b) displaying a dot pattern corresponding to each inputted character as each character is inputted; (c) counting a number of characters inputted; (d) generating a count after the input of each character; and (e) generating the dot pattern to be displayed according to each inputted character; said step (e) including the sub-steps of, (e1) generating a plurality of dot patterns having distinct sizes, and (e2) displaying the dot patterns; said sub-step (e1) generating the dot patterns such that a dot pattern size for displaying a first character is larger than a dot pattern size for displaying the first character and a second character and the size of the dot pattern for displaying the the first and second characters and a third character is smaller than a dot pattern size for displaying the first character and the second character; said sub-step (e1) reducing the dot pattern size in response to the inputting of each character until a predetermined number of characters have been inputted.
Claim 8
Independent Claim
185 words
A method for displaying characters in a form of dot patterns comprising the steps of: (a) inputting characters one at a time; (b) displaying a dot pattern corresponding to each inputted character as each character is inputted; (c) counting a number of characters inputted; (d) generating a count after the input of each character; and (e) generating the dot pattern to be displayed according to each inputted character; said step (e) including the sub-steps of, (e1) generating a plurality of dot patterns having distinct sizes, and (e2) displaying the dot patterns; said sub-step (e1) generating the dot patterns such that a dot pattern size for displaying a first character is larger than a dot pattern size for displaying the first character and a second character and the size of the dot pattern for displaying the the first and second characters and a third character is smaller than a dot pattern size for displaying the first character and the second character; said sub-step (e1) reducing the dot pattern size in response to the inputting of each character until a predetermined number of characters have been inputted.
Claim 9
Dependent Claim
163 words
A display apparatus for displaying characters, comprising: a keypad for inputting characters one at a time; a display, displaying each inputted character as each character is inputted; a counter, operatively connected to said keypad, counting the number of characters inputted and outputting a count after the input of each character; a controller, operatively connected to said keypad, said counter and said display, generating and regenerating character signal commands such that said display displays only a first character with a first size, displays only the first character and a second character, each with a second size, and displays only the first character, the second character and a third character, each with a third size, wherein the first size is larger than the second size, and the second size is larger than the third size, and said controller reduces the size of each character displayed by said display in response to the inputting of each character until a predetermined number of characters have been inputted.
Claim 10
Dependent Claim
163 words
A display apparatus for displaying characters, comprising: a keypad for inputting characters one at a time; a display, displaying each inputted character as each character is inputted; a counter, operatively connected to said keypad, counting the number of characters inputted and outputting a count after the input of each character; a controller, operatively connected to said keypad, said counter and said display, generating and regenerating character signal commands such that said display displays only a first character with a first size, displays only the first character and a second character, each with a second size, and displays only the first character, the second character and a third character, each with a third size, wherein the first size is larger than the second size, and the second size is larger than the third size, and said controller reduces the size of each character displayed by said display in response to the inputting of each character until a predetermined number of characters have been inputted.
