Abstract: A display device may include pixels and source lines that provide data line signals to the pixels. The display device may also include gate lines that provide gate signals to switches associated with the pixels. The display device may also include vertical gate lines disposed generally parallel to the source lines and coupled to the gate lines at cross point nodes. The display device may also include compensation lines, such that each compensation line is proximate to a respective vertical gate line. The compensation lines may transmit compensation signals having an opposite polarity as compared to respective gate signals to reduce or eliminate a kickback voltage on at least one of the plurality of pixels.

Abstract: A display may have a thin-film transistor (TFT) layer and color filter layer. Light blocking structures in an inactive area of the display may prevent stray backlight from leaking out of the display. The thin-film transistor layer may have a first substrate, a first black masking layer, a planarization layer, and a layer of TFT circuitry on the planarization layer. The color filter layer may have a second substrate and a second black masking layer on the second substrate. Light-cured sealant may be formed between the TFT layer and the color filter layer. Gaps may be formed in the second black masking layer to allow light to cure the sealant. At least a portion of the TFT circuitry may serve to block stray backlight penetrating through the gaps in the second black masking layer during normal operation of the display.

Abstract: A display may have an array of pixels to display images. Gate line driver circuitry may have stages that supply gate line signals. A gate line may be located in each row of the pixels. Each stage may have an output block that produces a respective one of the gate line signals and may have a carry block that separately produces a carry signal that is provided to a later stage in the gate line driver circuitry. A memory may be provided in at least some of the stages to store signals produced by the output blocks during intraframe pausing operations. At the end of an intraframe pause, the stored signals may be used in restarting production of the gate line signals by output blocks in the gate line driver stages. Circuitry may be used to separately reset the output block and suppress carry signal production by the carry block.

Abstract: A display may have a liquid crystal layer sandwiched between a thin-film transistor layer and a color filter layer. An upper polarizer may be placed on top of the thin-film transistor layer. A lower polarizer may be placed under the color filter layer. Components may be bonded to bond pads on the inner surface of the thin-film transistor layer using anisotropic conductive film. Bond quality may be assessed by probing probe pads that are coupled to the bond pads or by visually inspecting the bond pads through the thin-film transistor layer. Opaque masking material in the inactive area may be provided with openings to accommodate the bond pads. Additional opaque masking material may be placed on the underside of the upper polarizer and on the upper surface of the thin-film transistor layer to block the openings from view following visual inspection.

Abstract: Systems and methods for programming an electronic display in a double-row manner are provided. A system may include processing circuitry that generates image data and an electronic display that programs multiple rows of display pixels with different pixel data of the image data at the same time. This may allow double-row interlaced driving to reduce or eliminate image artifacts due to intra-frame pauses.

Abstract: An electronic device may include a display. The display may include display driver circuitry that is configured to provide image data to columns of pixels and gate driver circuitry that is configured to provide control signals to rows of pixels. The display may be operable at a native refresh rate that is equal to the highest refresh rate at which the display has full resolution. The display may also be operable in a high refresh rate mode with a high refresh rate that is twice (or some other scaling factor greater than) the native refresh rate. To enable operation at the high refresh rate mode, vertical resolution of the display may be sacrificed. In other words, rows of pixels may be grouped together into effective rows that are then scanned in sequence. The gate driver circuitry may be formed as thin-film transistor circuitry or from gate driver integrated circuits.

Abstract: A display may have an array of pixels arranged in rows and columns. Display driver circuitry may be provided along an edge of the display. Data lines that are associated with columns of the pixels may be used to distribute data from the display driver circuitry to the pixels. Gate lines in the display may each have a horizontal straight portion that extends along a respective row of the pixels and may each have one or more non-horizontal segments such as zigzag segments. The non-horizontal portion of each gate line may be connected to the horizontal straight portion of the gate line by a via. The non-horizontal portions may each have portions that are overlapped by portions of the data lines. Dummy gate line structures may be provided on the display that are not coupled to any of the pixels in the display.

Abstract: A display may have an array of pixels. Rows of pixels may receive gate line signals over gate lines. Display driver circuitry may have an adjustable clock generator that generates a series of clock pulses with different respective fall times to help equalize kickback voltages in the pixels of different rows. Within each row, gate lines may be provided with multiple parallel lines shorted at a series of tap points to help equalize kickback voltages across the pixels of different columns. A clock path may be formed between the clock generator and gate driver circuits. The clock path may run along an edge of the array of pixels. To help equalize kickback voltages in the pixels of different rows, the clock path may have first and second parallel metal lines that are selectively shorted to each other at a series of tap point locations along the clock path.

Abstract: A display may have an active area surrounded by an inactive border area. The display may be a liquid crystal display having a liquid crystal layer sandwiched between a color filter layer and a thin-film transistor layer. An upper polarizer may have a polarized central region that overlaps the active area of the display. The upper polarizer may also have an unpolarized portion in the inactive border area overlapping the border structures. The border structures may include colored material such as a white layer on the inner surface of the thin-film transistor layer. Binary information may be embedded into an array of programmable resonant circuits. The binary information may be a display identifier or other information associated with a display. The programmable resonant circuits may be tank circuits with adjustable capacitors, fuses, or other programmable components.
