摘要： The present disclosure generally relates to systems and techniques for calibrating displays to improve the white point uniformity between similar type devices. In one embodiment, a backlight includes multiple strings of LEDs, where each string is driven by a separate driver, or driver channel. Each string may be separately tested at a base current to determine its emitted chromaticity, and values indicative of the emitted chromaticities may be stored within the backlight as calibration values. The calibration values may then be used to determine the driving strength for each string that allows the display to produce the target white point when the light from the strings is mixed. Further, in certain embodiments, adjustments also may be made to the LCD panel based on the emitted chromaticities at the base current.

摘要翻译： 本公开通常涉及用于校准显示器以改善类似类型设备之间的白点均匀性的系统和技术。 在一个实施例中，背光源包括多个LED串，其中每个串由单独的驱动器或驱动器通道驱动。 每个串可以在基极电流下单独测试以确定其发射的色度，并且指示发射的色度的值可以作为校准值存储在背光中。 然后可以使用校准值来确定当来自弦的光被混合时允许显示器产生目标白点的每个串的驱动强度。 此外，在某些实施例中，也可以基于基极电流处的发射色度来调整LCD面板。

摘要： A liquid crystal display (LCD) is provided having a discontinuous electrode. In certain embodiments, different portions (such as finger- or slit-like extensions) of the discontinuous electrode may be at different depths relative to one another and/or may be of different widths relative to one another. Similarly, in other embodiments, the different portions of the discontinuous electrode may be spaced apart in a non-uniform manner.

摘要： Systems, methods, and devices for reducing the loss of transmittance caused by column inversion. To provide one example, an electronic display may include a display panel with columns of pixels and driver circuitry to drive the pixels using column inversion. Adjacent columns that are driven at like polarity are spaced more closely than adjacent columns driven at opposite polarities.

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： Systems, methods, and devices for performing column inversion using 2-column demultiplexers are provided. In one example, an electronic display may include a display panel with columns of pixels configured to be programmed with frames of image data and display driver circuitry. The display driver circuitry may include three demultiplexers, each respectively coupled to one pixel column of a first superpixel and one pixel column of a second superpixel. Each of the three demultiplexers may receive amplified image data of a single polarity per frame.

摘要： A liquid crystal display (LCD) is provided having transistors disposed within via holes having elongated (e.g., rectangular or oval) contact areas. The use of via holes having elongated contact areas allows an opaque mask defining an aperture for light transmission to be lengthened, thereby increasing the overall area of the aperture. The increase in the area of the aperture may increase the amount of light that can pass through the aperture.

摘要： Devices and methods related to high-contrast liquid crystal displays (LCDs) are provided. For example, such an electronic device may include an LCD with two liquid crystal alignment layers not symmetric to one another and upper and lower polarizing layers respectively above and below the alignment layers. Light transmittance through the plurality of pixels may increase monotonically with gray scale voltage. The display may operate using a gray scale level 0 voltage higher than a minimum gray scale level 0 voltage capability of the display. Additionally or alternatively, liquid crystal molecular alignment axes of the two alignment layers may be offset from one another by an angle other than a multiple of 180 degrees. Additionally or alternatively, a first polarizing axis of the upper polarizing layer or a second polarizing axis of the lower polarizing layer, or both, may be neither parallel nor perpendicular to one of the liquid crystal molecular alignment axes.
