摘要： A display has a light source layer having control inputs for controlling the light source layer to emit light such that the light output varies smoothly with position in a manner determined by the control inputs. An LCD panel or other spatial light modulator modulates light from the light source layer. The light source layer may be thin.

摘要： Methods and apparatus according to various aspects take as input image data in a lower-dynamic-range (LDR) format and produce as output enhanced image data having a dynamic range greater than that of the input image data (i.e. higher-dynamic range (HDR) image data). In some embodiments, the methods are applied to video data and are performed in real-time (i.e. processing of video frames to enhance the dynamic range of the video frames is completed at least on average at the frame rate of the video signal).

摘要： A process for reducing noise and temporal artifacts (e.g. walking LEDs) on a dual modulation display system by applying temporal filtering to rear modulation signals of a sequence of video frames. Flare and dimming rates are calculated for a current frame in the video. If a flare rate threshold is exceeded, an intensity of the backlight is limited to a predetermined flare rate. If a dimming rate threshold is exceeded, the backlight intensity is limited to a predetermined dimming rate. The limitations are applied, for example, on an element-by-element basis. In the event of a scene change, the limitations do not need to be applied. A forward modulation signal is calculated by taking into account any applied backlight limitations.
摘要翻译： 一种通过对视频帧序列的后调制信号应用时间滤波来减少双调制显示系统上的噪声和时间假象（例如步行LED）的过程。 为视频中的当前帧计算耀斑和调光率。 如果超过光斑速率阈值，则将背光的强度限制在预定的扩张率。 如果超过了调光率阈值，则将背光强度限制在预定的调光速率。 这些限制例如在逐个元素的基础上被应用。 在场景变化的情况下，不需要应用限制。 通过考虑任何应用的背光限制来计算正向调制信号。
