摘要： An active matrix display comprises a select driver (SD) to drive select electrodes (SE), and a data driver (DD) to supply data (D) to data electrodes (DE). Pixels (10) are associated with intersections of the data electrodes (DE) and the select electrodes (SE). The pixels (10) comprise a light emitting element (L) and a pixel driving circuit (PD). The pixel driving circuit (PD) receives a power supply voltage (VB) via a power supply electrode (PE), and data (D) via a data electrode (DE) to control a brightness of the light emitting element (L). A power supply (PS) supplies the power supply voltage (VB). The power supply electrodes (PE) are arranged to supply the power supply voltage (VB) to the pixel driving circuits (PD) of lines of pixels (10) extending in the same direction as the select electrodes (SE) or in the same direction as the data electrodes (DE). The load (AL; MA; IL) on the power supply electrodes (PE) caused by the pixels (10) associated with the lines of pixels (10) is determined (LD), and the level of the power supply voltage (VB) is controlled (CO) dependent on the load (AL; MA; IL).

摘要： A matrix display device comprises a matrix of optically addressable pixels (Pij). The pixels (Pij) comprise a light sensitive element (LSij) and a pixel light generating element (LGij). The light generating element (LGij) of a particular pixel (Pij) produces light with a brightness which depends on the state of the light sensitive element (LSij). The state of the light sensitive element (LSij) depends on an amount of light impinging on it. The matrix display further comprises a laser (LAS) which generates laser beam (LB), and a laser scanner (SCA) which scans the laser beam (LB) along the pixels (Pij). At the instant the laser beam (LB) impinges on the light sensitive element (LSij), the brightness of the laser beam (LB) determines the state of the light sensitive element (LSij), and thus the state of the pixel light generating element (LGij).

摘要： In an active matrix electroluminescent display, a plurality of rows of pixels are illuminated, defining at least two bands (10) of rows separated by a non-illuminated band (12). The bands (10) of rows of pixels scroll in the column direction over time, and at most 75% of the rows are illuminated at any point in time. This method is in essence a double bar scrolling method. By scrolling two bars, the required peak brightness is reduced as the effective overall duty cycle is increased. However, the period of illumination can still remain short, so that motion perception remains improved. The scrolling speed can be halved for the same frame rate or else the frame rate can be increased to reduce flicker.
摘要翻译：在有源矩阵电致发光显示器中，照射多行像素，限定由非照明带（12）隔开的至少两行行（10）。行列的带（10）随着时间沿列方向滚动，并且至多75％的行在任何时间点被照亮。这种方法本质上是一个双杠滚动方法。通过滚动两个条，所需的峰值亮度随着有效总占空比的增加而减小。然而，照明时期仍然很短，所以运动感觉仍然有所改善。对于相同的帧速率，滚动速度可以减半，否则可以增加帧速率以减少闪烁。
