Embodiment Construction

[0036] This disclosure describes an embodiment that utilizes a pixel circuit having a light emitting device, such as an organic light emitting diode (OLED), and a plurality of transistors, such as thin film transistors ( thin filmtransistors, TFT) and the like, arranged in rows and columns to form an AMOLED display. The pixel circuitry may include a pixel driver for the OLED. However, a pixel may include any light emitting device other than an OLED, and a pixel may include any transistor other than a TFT. The transistors in the pixel circuit can be N-type transistors, P-type transistors or combinations thereof. The transistors in the pixels may utilize amorphous silicon, nano / microcrystalline silicon, poly silicon, organic semiconductor technology (eg organic TFT), NMOS / PMOS technology or CMOS technology (eg MOSFET). In the specification, "pixel circuit" and "pixel" are used interchangeably. A pixel circuit may be a current-programmed pixel or a voltage-programmed pixel, an...

Description

technical field [0001] The present invention relates to display technology, in particular to methods and systems for driving light emitting device displays. Background technique [0002] Active-matrix organic light-emitting diodes (AMOLEDs) utilizing amorphous silicon (a-Si), polysilicon, organic or other drive backplanes have recently been developed due to their advantages over active liquid crystal displays. become more attractive. AMOLED displays utilizing a-Si backplanes have, for example, advantages including low temperature fabrication that expands the utilization of different substrates and enables flexible displays, reducing manufacturing costs. In addition, OLEDs produce high-resolution displays with wide viewing angles. [0003] An AMOLED display includes an array of rows and columns of pixels, each with organic light emitting diodes (OLEDs) and backplane electronics arranged in the row and column array. Because OLED is a current-driven device, the pixel circuit...
