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.

摘要： When a clock signal pulse number and a compensation-target-line address indicating a compensation-target row match, the following control is carried out with a time point being a starting point of a current measurement period, the time point being one horizontal scanning period after a time point of the match. At a current measurement period starting point and ending point, only the potential of the one of the clock signals applied to a unit circuit corresponding to the compensation-target row is changed. Throughout the current measurement period, the clock operation of the clock signals is stopped. A monitor enable signal, that is applied to a control terminal of an output control transistor for controlling active signal output to a monitor control line, is only set to a high level during the current measurement period.

摘要： An organic light emitting display includes a plurality of pixel row groups, a scan driver, a data driver, and a data distributor. Each pixel group includes the same number of pixel rows, and the pixel row groups are sequentially driven. The data distributor demultiplexes data signals for input into the pixels. The data signals are input to the pixels after threshold voltage compensation is performed at substantially a same time for pixels in each of the pixel row groups. Data signals are to be input to pixels in one pixel row group while threshold voltage compensation is performed for pixels in another pixel row group adjacent to the one pixel row group.

A display region of the array substrate (30) comprises a plurality of sets of data lines (33) and a plurality of scan lines (36), the plurality of sets of data lines (33) and the plurality of scan lines (36) intersecting each other to divide the display region into a plurality of pixel regions, a pixel electrode (32) is disposed in each of the pixel regions and electrically connected to the data lines (33); the pixel electrode (32) comprises a central pixel electrode (32a) and a peripheral pixel electrode (32b) adjacent to and electrically isolated from the central pixel electrode (32a). When the pixel region is driven, the peripheral pixel electrode (32b) and the central pixel electrode (32a) are at opposite polarities, thereby making the electrochromic material flowing from the central pixel region (32a) corresponding to the central pixel electrode (32a) to the peripheral pixel electrode (32b) and having been changed in color to fade in color.
