    Abstract: An electronic device may be provided with a display. An optical component window may be formed in the inactive area of the display. The optical component window may transmit infrared light from an infrared light source. The infrared light source may include a diffuser (52) to allow the light source to operate in a flood illumination mode and a structured light mode. The diffuser (52) may include liquid crystal material (64) between first and second substrates (58, 60). A sealant (62) may surround the liquid crystal layer (64), and one or more spacer walls (65-1, 65-2) may be located between the sealant (62) and the liquid crystal layer (64). An additional spacer wall may be used outside of the sealant to prevent metal from creating an electrical short between electrodes in the diffuser. Conductive material in the sealant may be used to couple a top electrode to a metal pad on a bottom substrate.

    Abstract: A layer of liquid crystal material may be interposed between display layers. The display layers may include thin-film transistor circuitry having subpixel electrodes for applying electric fields to subpixel portions of the layer of liquid crystal material. Subpixels of different colors may have different shapes and may have different liquid crystal layer thicknesses. These subpixel differences may be configured to slow the switching speed of subpixels of a certain color relative to other subpixels to reduce color motion blur when an object is moved across a black or colored background. The subpixels may have chevron shapes. Subpixels of a first color may have chevron shapes that are less bent than subpixels of second and third colors. In configurations with varying liquid crystal layer thicknesses, the subpixels of the first color may have thicker liquid crystal layers than the subpixels of the second and third colors.

    Abstract: Pre-charging display screen sub-pixels, such as aggressor sub-pixels, prior to the application of a target data voltage to the aggressor sub-pixels is provided. In some examples, a target voltage of a sub-pixel in a previous row in the scanning order of the display can be used to pre-charge sub-pixels. The row of sub-pixels to be pre- charged can be switched on during the updating of another row of sub-pixels. In this way, for example, target voltages applied to data lines while an update row is connected to the data lines, e.g., to update the update row, can be applied to the row to be pre-charged as well.

    Abstract: With respect to liquid crystal display inversion schemes, a large change in voltage on a data line can affect the voltages on adjacent data lines due to capacitive coupling between data lines. The resulting change in voltage on these adjacent data lines can give rise to visual artifacts in the data lines' corresponding sub-pixels. Various embodiments of the present disclosure serve to prevent or reduce persisting visual artifacts by offsetting their effects or by distributing their presence among different colored sub-pixels. In some embodiments, this may be accomplished by using different write sequences during the update of a row of pixels.

    Abstract translation: 对于液晶显示反转方案，由于数据线之间的电容耦合，数据线上的电压大的变化可能影响相邻数据线上的电压。 由此产生的这些相邻数据线上的电压变化可能引起数据线对应子像素中的视觉伪像。 本公开的各种实施例用于通过抵消其效果或通过在不同的彩色子像素之间分布它们的存在来防止或减少持久的视觉伪影。 在一些实施例中，这可以通过在更新一行像素期间使用不同的写入顺序来实现。

    Abstract: A liquid crystal display may have upper and lower polarizers (22, 24). A color filter layer (12) and a thin film transistor layer (14) may be located between the upper and lower polarizers. A liquid crystal layer (16) may be interposed between the color filter layer and the thin film transistor layer. A first optical film layer (18) that includes a birefringent compensating layer (62) may be located between the upper polarizer and the color filter layer. A second optical film layer (20) that may be devoid of birefringent compensating layers may be located between the thin film transistor layer and the lower polarizer. A grid of metal signal lines (66) may be used to distribute signals to thin film transistors on the thin film transistor layer. A black mask (68) may be interposed between the grid of signal lines and the thin film transistor layer.

    Abstract: Common electrodes (Vcom) of integrated touch screens can be segmented into electrically isolated Vcom portions that can be operated as drive lines and/or sense lines of a touch sensing system. The touch screen can include high-resistivity connections between Vcom portions. The resistivity of the high-resistivity connections can be high enough so that touch sensing and image display can be performed by the touch screen, and the high-resistivity connections can provide an added functionality by allowing a charge build up on one of the Vcom portions to be spread to other Vcom portions and/or discharged from system by allowing charge to leak through the high-resistivity connections. In this way, for example, visual artifacts that result from charge build up on a Vcom portion can be reduced or eliminated.
