17‐3: An 8.3‐inch 1058‐ppi OLED Display with Side‐by‐Side Pixel Structure Fully Fabricated by Photolithography

A simple pixel circuitry for OLED display

Active OLED are good challenger for becoming the new commonality technology for large displays. Current-controlled pixels that are used in several prototypes are very complex and do not correct all the problems of the use of OLED pixels. This paper presents a different approach to solve these problems. It suggests keeping the pixel circuitry as simple as possible and to put a correction mechani...

Static active-matrix OLED display without pixel refresh enabled by amorphous-silicon non-volatile memory

Yifei Huang Bahman Hekmatshoar (SID Student Member) Sigurd Wagner James C. Sturm Abstract — An active-matrix organic light-emitting-diode (AMOLED) display which does not require pixel refresh is demonstrated. This was achieved by replacing the thin-film transistor (TFT) that drives the OLED with a non-volatile memory TFT, in a 2-transistor pixel circuit. The threshold voltage of the non-volatil...

Quantum Dot Display Technology and Comparison with OLED Display Technology

QLED TV is a new television technology that is taking many of its cues from OLED TV technology. It consists of extremely small light-emitting crystals called quantum dots. Most TVs today including all of those made by companies and just about every other TV brand are based on decades-old LCD, or liquid crystal display, technology. In the past few years’ Better technology and more advanced manuf...

3-TFT OLED Pixel Circuit for High Stability with In-pixel Current Source

A new 3-TFT voltage-programmed pixel circuit with an in-pixel current source is presented, which can be largely insensitive to the TFT threshold voltage shift. The fabricated pixel circuit provides OLED current ranging from 25nA to 2.9μA, an on/off ratio of 116 at typical QVGA display timing. Author
