摘要： Methods and systems to dynamically adjust a voltage supply of a display are provided. Systems are provided to receive a digital data input indicative of an amount of luminance to be emitted from the display, to determine a desired supply voltage to supply to the display based on the received digital data, and to adjust an adjustable voltage supply according to the determined desired supply voltage. Furthermore, the methods and systems disclosed herein provide for dynamically separately controlling supply voltages supplied to distinct subsections of the display. Systems and methods are also provided for operating a display device in an idle mode by turning off subsections of the display that would otherwise be shown dark and thereby save energy required to program the subsections with display information.

摘要： A system is provided for using raw grayscale image data, representing images to be displayed in successive frames, to drive a display having pixels that include a drive transistor and an organic light emitting device. The system determines whether the raw grayscale image data for each pixel falls within a high range or a low range. Raw grayscale image data that falls within the low range is converted to higher grayscale values, and the pixels are driven with currents corresponding to the higher grayscale values during time periods that are shorter than complete frame time periods. Raw grayscale image data that falls within the high range is converted to higher grayscale values, and the pixels are driven with currents corresponding to the higher grayscale values during time periods that are shorter than complete frame time periods and different from the time periods of the low range image data.

摘要： Raw grayscale image data, representing images to be displayed in successive frames, is used to drive a display having pixels that include a drive transistor and an organic light emitting device by dividing each frame into at least first and second-frames, and supplying each pixel with a drive current that is higher in the first sub-frame than in the second sub-frame for raw grayscale values in a first preselected range, and higher in the second sub-frame than in the first sub-frame for raw grayscale values in a second preselected range. The display may be an active matrix display, such as an AMOLED display.

摘要： Aspects of the present disclosure provide for manufacturing an organic light emitting diode (OLED) by forming two terminals of the OLED on two substrates of the display, and then depositing a plurality of layers of the OLED on one or both of the two terminals to form a first portion and a second portion of the OLED on each substrate. The two portions are joined together to form an assembled OLED. The deposition of the two portions can be stopped with each portion having approximately half of a common layer exposed. The two portions can then be aligned to be joined together and an annealing process can be employed to join together the two parts of the common layer and thereby form the OLED.

摘要： Circuits for programming a circuit with decreased programming time are provided. Such circuits include a storage device such as a capacitor for storing display information and for ensuring a driving device such as a driving transistor drives a light emitting device according to the display information. To increase programming time, the pixel circuits may be pre-charged or a biasing current may be applied to charge and/or discharge a data line and/or the driving device. Aspects of the present disclosure allow for the biasing current to drain partially through the storage device to allow the portion of the biasing current applied to the driving device to remain small while the data line discharges. Furthermore, the present disclosure provides display architectures and operation schemes for display arranged in segments each including a plurality of pixel circuits.0

摘要： A local priority-based scanning scheme that focuses scanning to areas of a display panel whose measured characteristics are under continuous change (e.g., aging or relaxation). The algorithm identifies areas or regions needing compensation, using a current measurement from a single pixel in an area as a candidate to determine whether the rest of the region needs further compensation. The algorithm thus detects newly changed areas quickly, focusing time-consuming measurements on those areas that need high attention. Optionally, neighboring pixels sharing the same state (e.g., aging or overcompensated) as the measured pixel can be adjusted automatically given the likelihood that the neighboring pixels will also require compensation if the measured pixel needs compensation.

摘要翻译： 本地基于优先级的扫描方案，其将扫描重点集中在其测量特征处于连续变化（例如，老化或松弛）的显示面板的区域。 该算法识别需要补偿的区域或区域，使用来自区域中的单个像素的当前测量作为候选来确定该区域的其余部分是否需要进一步的补偿。 因此，该算法可以快速检测新改变的区域，将需要高度关注的那些区域的耗时测量集中起来。 可选地，如果所测量的像素需要补偿，相邻像素也将需要补偿的可能性，可以自动调整共享与测量像素相同的状态（例如，老化或过补偿）的相邻像素。
