DIGITAL LIGHT VALVE ADDRESSING METHODS AND APPARATUS AND LIGHT VALVES INCORPORATING SAME

摘要

Display systems (200) include display drivers (202) that receive digital video data and retain digital pixel values corresponding to a row of pixels of a display panel (212). The retained digital pixel values are digitally compared with a digital count produced by a digital counter (335) and at a transition time determined by the comparison of the digital pixel value and the digital count, a data ramp is applied to the signal. The data ramp signal is configured to be time varying so that the transition time at which the data ramp is applied to the pixel can be used to establish a pixel voltage corresponding to a desired image value. In an example, digital pixel values corresponding to a first row of pixels are processed so that the data ramp signal is applied to each pixel of the first row at transition times determined by the digital image associated with each pixel.
