Abstract: A driving system and method for electroluminescence displays having a matrix of electroluminescence elements arrayed in rows and columns with a control circuit for discharging each anode line to a column equalization bus (CEB), includes connecting the charged anode line to the CEB at the end of activation of each anode line. Discharging and subsequent de-activation of the anode line are allowed by charge-sharing with un-activated anode lines that are to be activated for the next row. This is accomplished by connecting the charged anode line to the CEB. In displaying images, anode lines are activated for a number of time periods according to gray scale or color data. Anode lines are consequently de-activated accordingly at different times during a lighting phase for each row display time. When anode lines are discharged through charge sharing on the CEB, a control circuit maintains the voltage on the CEB below a level that may cause inadvertent activation of the de-activated elements.

Abstract: An automatic clock phase selector for applying input pulses of selected phases to a counter to enable an AGC gate generator and a burst-gate generator during selected time intervals is described. The automatic clock phase selector includes a generator for generating a train of true clock pulses and a train of complementary clock pulses. A pulse train selector receives these clock pulse trains and a flyback pulse. The pulse train selector is responsive to the time coincidence between a selected edge of the flyback pulse and the positive or negative portion of a true clock pulse for coupling a selected train of clock pulses to the counter. In this manner, the intervals during which the AGC gate generator and the burst-gate generator are enabled track with the occurrence of the selected edge of the flyback pulse.

The phasing circuit outputs a signal indicative of the test. The system includes means responsive to the phasing circuit for adjusting the phase of the locally generated vertical sync pulses, and a mode recognition circuit for determining whether the received television signal includes equalizing pulses in a vertical interval.
