摘要： Systems, methods, and devices for performing column inversion using reordered image data are provided. In one example, an electronic display may include a display panel with columns of pixels and driver circuitry to drive the pixels using column inversion. The driver circuitry may drive pixels of a first superpixel in a first color order and drive pixels of an adjacent second superpixel in a second color order, such that more pixels are driven sequentially at a common polarity than would have been driven sequentially at the common polarity were the pixels of the first superpixel driven at the same color order as the pixels of the second superpixel.

摘要： Present techniques involve methods and systems of inversion patterns for pixels in a display. Inversion techniques involve driving image signals having a first polarity to data lines of a pixel matrix during a first time period and driving image signals having an opposite polarity to the data lines during a second time period. In some embodiments, the pixels may be configured to have electrodes having only two finger electrodes, thus widening the distance between electrodes and decreasing the susceptibility for crosstalk between pixels. In some embodiments, horizontal cross-talk of electromagnetic fields between pixels may be further reduced by configuring the data line driving scheme such that voltage polarity is flipped for the pixels along every two, three, or more data line columns. Furthermore, a Z inversion pattern may be employed to reduce the occurrence of undesirable display artifacts.

摘要： Methods and devices for improving image quality in a display having multiple common voltage layers (VCOMs) are provided. In one example, a method may include maintaining a deactivation signal on pixels of the display after programming a frame of data onto the pixels of the display, but before a touch sequence. The method may also include supplying a first data signal to each pixel of a first set of pixels coupled to a first VCOM while maintaining the deactivation signal. The method may include supplying a second data signal to each pixel of a second set of pixels coupled to a second VCOM while supplying the first data signal. The first data signal is supplied to each pixel of the first set of pixels and the second data signal is supplied to each pixel of the second set of pixels to inhibit image distortion during the touch sequence.

摘要： Embodiments of a system that includes one or more integrated circuits are described. During operation, the system may determine an intensity setting of the light source based on at least a portion of a video image, such as the portion of the transformed video image that includes spatially varying visual information in the video image. Moreover, the system may modify the video image so that a product of the intensity setting and a transmittance associated with the modified video image approximately equals a product of a previous intensity setting and a transmittance associated with the video image. For example, the modification may include scaling brightness values in the transformed video image. Next, the system may identify a region in the video image in which the scaling of the brightness values results in a visual artifact associated with reduced contrast. For example, the region may include a bright region surrounded by a darker region. Then, the system may reduce the scaling of the brightness values in the region to, at least partially, restore the contrast, thereby reducing the visual artifact. Additionally, the system may spatially filter the brightness values in the video image to reduce a spatial discontinuity between the brightness values of pixels within the region and the brightness values in a remainder of the video image.

摘要： Better performance can be provided for a display system that has semiconductor microelectronic components such as demultiplexors, gate line and data line drivers, and pixel switches formed on the display substrate, e.g., a glass substrate that constitutes part of an active matrix display panel. A gate source capacitance of a constituent transistor of one of these microelectronic components, e.g., a pixel thin film transistor (TFT) that is part of a particular display element, may be measured using a replica component that emulates the behavior of the component.

摘要： Embodiments of a system that includes one or more integrated circuits are described. During operation, the system receives a video image, that when displayed, includes a picture portion, a non-picture portion, and a subtitle which is superimposed on at least a subset of the non-picture portion, where the non-picture portion has an initial brightness value. Then, the system scales the brightness of pixels corresponding to a remainder of the non-picture portion of the video image to have a new brightness value that is greater than the initial brightness value to reduce user-perceived changes in the video image associated with backlighting of a display that displays the video image, where the remainder of the non-picture portion excludes the subset of the non-picture portion.
