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。

摘要： The present invention relates to the driving of optical displays, such as Dynamic Foil Displays, and provides dynamic adaptation of the number of subfields into which frame times of such displays are divided. The number of subfields can thus be selected (1202) depending on for example the ambient light conditions (1201) and image quality requirement. In particular, a smaller number of subfields facilitates brighter images, whereas a larger number of subfields facilitates an increased number of gray scales and/or motion artifact reduction.

摘要： A display device comprising a plurality of pixels (26), a light source (23), and addressing means (24, 25) for coupling a selected pixel to said light source to thereby emit light, wherein the addressing means (24, 25) are arranged to address each pixel using pulse-width modulation (PWM). Further, the display comprises means (20) for amplitude modulating the intensity of said light source (23). The combination of the two modulations generates an exponentially distributed emitted light intensity, enabling proper gray scale rendering for a limited resolution in the time domain.

摘要： The invention provides an illumination system comprising a light-emitting device which excites a first luminescent element, which forms part of the light-emitting device. The light emitted from the first luminescent element and/or the light emitted by the light-emitting device excite a second luminescent element, physically separated from the light-emitting device. By employing two luminescent elements, the first element in the light-emitting device, and the second element physically separated from the light-emitting device, such as on a cover plate, the conversion of light produced by the light-emitting device is performed at both a “local” and a “remote” location, respectively, and the amount of luminescent material required at the remote location may be reduced compared to the situation of the prior art where the light conversion was only performed at a remote location.

摘要： A driving circuit (10) for driving a plurality of light sources (1) arranged in a series configuration (2) is described. A controllable current source (20) is connected to said series arrangement of light sources. Each light source (1(i)) is bridged by a corresponding controllable switch (25(i)). A controller (30) controls the operation of the current source (20) to set a current level and controls the operative states of the respective switches (25(i)) in order to individually control the light output of the corresponding light sources. The controller (30) is capable of individually setting the switch control signals (SL(O) for the respective switches (25(i)). Especially, the controller (30) is capable of boosting the light output of one selected light source (1(x)) while maintaining the light output of other light sources in the series arrangement (2). To this end, the current level is increased while the other light sources are dimmed.
