Compensating for parasitic voltage drops in circuit arrays
| DWPI Title: System for compensating for parasitic voltage drops in circuit arrays used in displays and memory circuits, has resistive components which differ in resistance and are connected to array circuit |
| Abstract: Various technologies for improving uniformity of operation of elements in an array circuit are described herein. In an exemplary embodiment, a plurality of resistive elements are incorporated into an array circuit such that voltages developed across any two elements is substantially the same when an equal voltage is applied to energize the elements. In a crossbar array circuit that comprises a plurality of elements arranged in rows and columns, the resistance of each of the resistive elements is based upon a row or column to which the resistive element is connected. |
| Use: System for compensating for parasitic voltage drops in circuit arrays (claimed) used in displays and memory circuits. |
| Advantage: A tiled configuration of elements in an array circuit may be arranged such that parasitic voltage drops caused by parasitic resistances are substantially equalized among energizing current paths in the array circuit, without requiring the use of balancing resistors. |
| Novelty: The system has an array circuit (202) comprising four elements (E2) arranged in a regular pattern such that the array circuit comprises a first group of terminals that comprises first and second terminals (T2-R1,T2-R2), and a second group of terminals that comprises third and fourth terminals (T2-C1,T2-C2). Each of the elements is energized by way of a respective pair of terminals, each pair of terminals comprising a terminal in the first group of terminals and a terminal in the second group of terminals. Resistive components are connected to the array circuit. The resistive components includes a first resistive component connected to the first terminal and a second resistive component connected to the second terminal. The first resistive component has a higher resistance than the second resistive component. |
