Abstract: Electronic devices may be provided with displays that have polarizers. A polarizer may have a polymer layer that has a portion covered with a dichroic dye to form a polarized region and a portion that is free of dichroic dye to form an unpolarized region. The unpolarized region may be formed by masking the polymer layer during a dye coating process. Masks may be formed from polymers. The shape of the mask may define the shape of the unpolarized region. The mask may be left in place within the polarizer or may be removed from the polarizer during fabrication. Unpolarized regions may also be formed by light bleaching, chemical bleaching, and material removal techniques. Bleached areas may be chemically stabilized. A moisture barrier layer may be incorporated into the polarizer to help prevent the unpolarized region from reverting to a polarized state.

Abstract: A display may have a layer of liquid crystal material between a color filter layer and a thin-film transistor layer. Column spacer structures may be formed between the color filter layer and the thin-film transistor layer to maintain a desired separation between the color filter and thin-film transistor layers. The column spacer structures may be formed from polymer structures such as photoresist pillars and may include metal pads. The metal pads may be formed on the upper surface of the thin-film transistor layer or the lower surface of the color filter layer. The photoresist pillars may be formed on a surface in the display such as the lower surface of the color filter layer. Column spacer structures may include main spacer structures, subspacer structures, and intermediate thickness spacer structures to enhance pooling mura and light leakage performance.

Abstract: A method is provided for calibrating a display having color channels. Each color channel is capable of adjusting settings for pixel values at gray level entries. The method includes selecting a gray level entry for calibration. The method also includes providing a target white point in chromaticity coordinates (x, y) and a target brightness at the selected gray level entry to the display. The method further includes adjusting the setting for the pixel values for the color channels at the selected gray level entry such that the display achieves the target white point and the target brightness at an adjusted pixel value.

Abstract: Displays such as liquid crystal displays may be provided with transparent substrates that minimize light leakage from the display. The transparent substrates may include a thin-film transistor substrate having thin-film transistors formed on a surface of the thin-film transistor substrate and a color filter substrate having color filter elements formed on a surface of the color filter substrate. The thin-film transistor substrate may be formed from a material having a relatively low photo-elastic constant. The color filter substrate may be formed from a material having a relatively low photo-elastic constant. Reduced birefringence effects in the thin-film transistor substrate and the color filter substrate may help minimize light leakage from the display when some or all of the display experiences internal or external stresses.
