The concept of 'negative capacitance', which consists of a differentiation circuit, an inverting voltage amplifier and a voltage-to-current converter, was introduced to the driving of PMOLED to shorten the current setting time even at a small current level. This new driving circuit enabled to show an accurate gray scale with both PWM and PAM methods, and is also applicable to a current-programmed AMOLED.
