DISPLAY DEVICE WITH SYSTEMATIC SMART PIXEL

摘要

PROBLEM TO BE SOLVED: To reduce or eliminate at least some of nonidealities by providing a driving/compensating circuit which is so selected as to at least reduce >=1 nonideality and arranging at least part of the driving/compensating circuit in a 2nd substrate area. SOLUTION: The systematic LED 11 of the driving/compensating circuit is controlled by a systematic FET p1. The gate voltage Vc of the FET P1 determines the current of the LED 11. A transistor P2 resets Vc to Vdd with a short active low pulse on RST. This driving/compensating circuit is operated by the systematic FET P1 selected as an arbitrary choice and the FET P1 is arranged in the 2nd substrate area nearby the LED 11. Then this driving/ compesating circuit relates to systematic smart pixels of the display device and performs compensation for nonidealities each time a given pixel is addressed or reset.
