Abstract
This paper presents a novel parallel addressingscheme for voltage-programmed active-matrix organic lightemittingdiode (OLED) displays which provides high precisionrecovery of the threshold voltage shift. As a result, the uniformityover the panel is significantly improved. In addition, a new pixelcircuit is presented that is capable of providing a predictablyhigher current as the pixel ages, so as to compensate for the OLEDluminance degradation.Index Terms—Active-matrix organic light-emitting diode(AMOLED), hydrogenated amorp ....etc

Scientific research in the area of semiconducting organic materials as the active substance in light emitting diodes (LEDs) has increased immensely during the last four decades. Organic semiconductors was first reported in the 60:s and then the materials where only considered to be merely a scientific curiosity. (They are named organic because they consist primarily of carbon, hydrogen and oxygen.).

ABSTRACT :-
Over the time there are many changes came into the field of output/display devices. In this field first came the small led displays which can show only the numeric contains. Then came the heavy jumbo CRTs (Cathode Ray Tubes) which are used till now. But the main problem with CRT is they are very heavy & we couldn’t carry them from one place to another the result of this CRT is very nice & clear but they are very heavy & bulky & also required quiet large area then anything else.
Then came the very compa ....etc

INTRODUCTION
Efficient control of D.C motor speed is very economical to any industries for that reason we are using full wave rectifier in which we are using triacs as switches because of bi-directional nature of triacs we are preferred instead of using thyrister as a switches. To obtain a four quadrant operation we need 8 switches if we use thyristers (this circuit called dual converter) and if we use triacs we need 4 switches only.

Abstract
This paper presents a novel pixel design for activematrix organic light emitting diode (AM-OLED) displays usingnanocrystalline silicon thin-film transistors (TFTs). The proposedpixel design can effectively reduce the variation of its storeddisplay data caused by the leakage current of nanocrystallinesilicon TFTs, which can in turn increase the contrast resolutionof AM-OLED displays. With a proper setting of its capacitors,the proposed pixel design can achieve a 5.55 reduction on itsdisplay-data variation while requiring only a ....etc

ABSTRACT
Organic light emitting diode (OLED) display technology has been grabbing headlines in recent years. Now one form of OLED displays, LIGHT EMITTING POLYMER (LEP) technology is rapidly emerging as a serious candidate for next generation flat panel displays. LEP technology promises thin, light weight emissive displays with low drive voltage, low power consumption, high contrast, wide viewing angle, and fast switching times.
One of the main attractions of thi ....etc
