Claim 1
Independent Claim
189 words
In a display system, the combination of: a. a plurality of switching transistors arranged in columns and rows with each column comprising one transistor from each row and each row comprising one transistor from each column; b. row lines or column lines commonly connecting the bases of all transistors in a row or column; c. the other of said row lines or column lines electrically connecting the emitters of all transistors in a row or column; d. row select means coupled to the row lines for selecting a specific row for actuation; e. column select means coupled to the column lines for selecting specific columns for actuation; f. means for sequentially actuating one of said row select means and said column select means to obtain sequential actuation of the corresponding row lines or column lines; and g. means for selectively actuating the other of said row select means and said column select means, in accordance with the image to be displayed, in synchronization with said sequential actuation of said one thereof, such that each coincidental actuation of a row line and a column line turns on a corresponding transistor.

In a display system, the combination of: a. a plurality of switching transistors arranged in columns and rows with each column comprising one transistor from each row and each row comprising one transistor from each column; b. row lines or column lines commonly connecting the bases of all transistors in a row or column; c. the other of said row lines or column lines electrically connecting the emitters of all transistors in a row or column; d. row select means coupled to the row lines for selecting a specific row for actuation; e. column select means coupled to the column lines for selecting specific columns for actuation; f. means for sequentially actuating one of said row select means and said column select means to obtain sequential actuation of the corresponding row lines or column lines; and g. means for selectively actuating the other of said row select means and said column select means, in accordance with the image to be displayed, in synchronization with said sequential actuation of said one thereof, such that each coincidental actuation of a row line and a column line turns on a corresponding transistor.
Claim 3
Dependent Claim
37 words
The display system according to claim 1 and further including a matrix of load elements for generating visible character images when energized in predetermined combinations, said load elements respectively connected to a collector of a switching transistor.
Claim 4
Dependent Claim
31 words
The display system according to claim 1 wherein the row select means includes means for discharging the previous row line in response to actuation of the row line next in sequence.
Claim 5
Dependent Claim
24 words
The display system according to claim 1 further including means for deactuating all the column lines after all row lines have been sequentially actuated.
Claim 6
Dependent Claim
24 words
The display system according to claim 1 wherein said load elements comprise heat dissipating devices, and said display system constitutes a thermal printing system.
Claim 7
Dependent Claim
83 words
The display system of claim 1 wherein said means for selectively actuating the other of said row select means and said column select means includes a driver circuit for selectively connecting each corresponding row line or column line to a supply voltage in response to logic control signals; and logic means coupled to said driver circuit for selectively operating said driver circuit to connect the corresponding row lines or column lines to the voltage supply in accordance with the image to be displayed.
