Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
A display element comprising: an actuator including a piezoelectric film and a pair of electrodes coated onto at least a portion of a pair of respective surfaces of said piezoelectric film; a flexing portion, in contact with one of said pair of electrodes, for supporting said actuator; a fixed portion for holding said flexing portion so that said flexing portion can move; means, connected to said actuator, for transmitting a displacement of said actuator; and a plate for transmitting light, disposed closely to said displacement-transmitting means; wherein a voltage is applied into said actuator through said pair of electrodes so as to control a rest position and a displacement of said actuator as well as controlling a contact and a separation between said displacement-transmitting means and said plate so that a light emission at a predetermined position in said plate is controlled.
Claim 2
Dependent Claim
45 words
A display element of claim 1, wherein said flexing portion and said fixed portion are portions of a ceramic substrate having a unitary structure, and said ceramic substrate is formed of a cavity so that said flexing portion has a plate shape and is thin.
Claim 3
Dependent Claim
154 words
A display apparatus comprising a plurality of display elements each comprising: an actuator including a piezoelectric film having a pair of surfaces and a pair of electrodes coated onto at least a portion of a pair of respective surfaces of said piezoelectric film; a flexing portion, in contact with one of said pair of electrodes, for supporting said actuator; a fixed portion for holding said flexing portion so that said flexing portion can move; means, connected to said actuator, for transmitting a displacement of said actuator; and a plate for transmitting light, disposed closely to said displacement-transmitting means; wherein a voltage is applied into said actuator through said pair of electrodes so as to control a rest position and a displacement of said actuator as well as controlling a contact and a separation between said displacement-transmitting means and said plate so that a light emission at a predetermined position in said plate is controlled.
Claim 4
Dependent Claim
123 words
A display element comprising: a laminated actuator including a laminated piezoelectric body including a plurality of piezoelectric layers and a plurality of electrode layers, wherein said piezoelectric layers and said electrode layers are laminated; a fixed portion for holding said laminated actuator; means, connected to said actuator, for transmitting a displacement of said actuator; and a plate for transmitting light, disposed closely to said displacement-transmitting means; wherein a voltage is applied into said laminated actuator through said electrode layers so as to control a rest portion and a displacement of said laminated actuator as well as controlling a contact and a separation between said displacement-transmitting means and said plate so that a light emission at a predetermined position in said plate is controlled.
Claim 5
Dependent Claim
130 words
A display apparatus comprising a plurality of display elements each comprising: a laminated actuator including a laminated piezoelectric body including a plurality of piezoelectric layers and a plurality of electrode layers, wherein said piezoelectric layers and said electrode layers are laminated; a fixed portion for holding said laminated actuator; means, connected to said actuator, for transmitting a displacement of said actuator; and a plate for transmitting light, disposed closely to said displacement-transmitting means; wherein a voltage is applied into said laminated actuator through said electrode layers so as to control a rest position and a displacement of said laminated actuator as well as controlling a contact and a separation between said displacement-transmitting means and said plate so that a light emission at a predetermined position in said plate is controlled.
Claim 6
Dependent Claim
32 words
A display apparatus of claim 3, wherein a number of said display elements for displaying black and white is substantially the same as the number of said display elements for displaying color.
Claim 7
Dependent Claim
32 words
A display apparatus of claim 5, wherein a number of said display elements for displaying black and white is substantially the same as the number of said display elements for displaying color.
Claim 8
Dependent Claim
57 words
A display element having at least one assembly of a piezoelectric actuator carried by a flexible element which is flexed by operation of the actuator, and a light-transmitting element whose light emission is controlled by flexing of the flexible element or elements, whereby light emission from said light-transmitting element is controlled by operation of said piezoelectric actuator.
