摘要： In an active matrix electroluminescent display device, an overall brightness level of an image to be displayed in a frame period is determined. A drive transistor of each pixel is controlled in dependence on an input drive signal for the pixel and on the overall brightness level, for example using a signal processor (30) to vary the pixel drive signals. This arrangement can control the pixels to limit the maximum currents drawn by the pixels, thereby limiting the cross talk effects resulting from voltage drops along row or column conductors. If an image is bright, the pixel drive levels across the image (or at least a part of the image) can be reduced, so that the maximum brightness is reduced.

摘要： The present invention relates to a driver for a string (STi) of series arranged light emitting diodes (D1i, D2i, D3i) of which at least two emit light having different spectra. The driver comprises a main power supply (PAi) which has outputs coupled across the string (STi) to supply a main current (IAi) to the string (STi). A secondary power supply (PBi) is coupled to at least one of junctions (J1i) between successive light emitting diodes (D1i, D2i) in the string (STi) to supply or withdraw a delta current (IBi) from the junction (J1i). The delta current (IBi) is at least a factor 5 smaller than the main current (IAi). A controller (CO) controls the secondary power supply (PBi) to generate the delta current (IBi) to obtain a desired spectral composition of the mixed light emitted by the string (STi).

摘要： The present invention relates to a method and a system of reducing motion blur in a liquid crystal cell. A basic idea of the invention is to process, in an LCD system, a luminance component (Y) of a picture frame to provide motion blur reduction, wherein overdrive is applied to the luminance component only. First, a luminance component related to a first picture frame is stored. Thereafter, a luminance component of a subsequent picture frame is acquired. To reduce motion blur in the LCD, a modified luminance component (Y′) is created based on a difference between the value of the luminance component of the subsequent frame and the value of the luminance component related to the first frame. Hence, based on the value of the difference in the luminance components, and color components (U,V) of the subsequent picture frame, a drive voltage is applied to the LC cell.
摘要翻译：本发明涉及一种降低液晶单元中运动模糊的方法和系统。本发明的基本思想是在LCD系统中处理图像帧的亮度分量（Y）以提供运动模糊减少，其中过驱动被应用于亮度分量。首先，存储与第一画面相关的亮度分量。此后，获取后续图像帧的亮度分量。为了减少LCD中的运动模糊，基于后续帧的亮度分量的值和与第一帧相关的亮度分量的值之间的差异创建修改的亮度分量（Y'）。因此，基于亮度分量的差值和后续图像帧的颜色分量（U，V），向LC单元施加驱动电压。
