Circuit for driving a multiple-element display |
摘要 |
A circuit for driving a display device having n display elements, where n is a positive integer greater than one, comprises a device for poviding a repetitive digital signal having a predetermined sequence of n digital values. The digital signal is converted to analog form in accordance with a predetermined transfer function and the resulting analog signal is compared with a second signal. A display enable signal is generated in the event that the magnitude of the analog signal bears a predetermined relationship to the magnitude of the second signal. A decoder circuit has a plurality of output terminals at which n distinct output signals, corresponding respectively to the n digital values, can be provided. The decoder circuit is responsive to the display enable signal for providing one of the n output signals when it receives the corresponding one of the n digital values.
