  • Publication number: 20190148465
    Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

  • Publication number: 20190121183
    Abstract: A display may have contacts that mate with a flexible printed circuit. The contacts may be used in providing data and control signals to pixels. A metal layer may be patterned to form metal traces for signal lines that extend outwardly towards an edge of the display from the contacts. Delamination stopper structures may be formed along the periphery of the display to inhibit delamination between layers of material on the display. The delamination stopper structures may be formed from bent portions of the metal traces, a slot-shaped inorganic layer opening that runs perpendicular to the metal traces, and a segmented trench in an organic layer. A corrosion blocker structure may be formed by creating metal trace gaps in the metal traces that are each bridged by a pair of vias that are shorted together using transparent conductive material such as a pair of indium tin oxide layers.

  • Patent number: 10101853
    Abstract: Thin-film transistor circuitry for a display may include conductive layers such as transparent conductive layers and metal layers and may include dielectric layers. The dielectric layers may include buffer layers, interlayer dielectric, gate insulator, and organic planarization layers. The organic planarization layers may be patterned photolithographically to form vias, trenches, and other structures. Trenches may be formed by removing the planarization layer in a strip. When planarization material is removed for forming a trench or other structure, a step is formed in the planarization material. Metal lines such as data lines and other signal lines may cross steps in the planarization material. To prevent shorts between lines, a step may have protrusions that help eliminate metal etch residue. Vias may be reduced in depth by forming metal bumps and dielectric bumps under the vias and by forming other via structures.

  • Patent number: 10048788
    Abstract: Improvement of visual uniformity of an integrated touch screen display is provided. A touch screen can include common electrodes separated by gaps in a Vcom layer. To improve visual non-uniformity in the display resulting from the gaps, a first set of semi-transparent dummy features (primary-dummy features) can be formed on a second layer at the locations of the gaps, and a second set of dummy features (supplementary-dummy features) can also be formed on the second layer or another layer to mitigate low spatial resolution of the primary-dummy features and/or non-uniform spacing of the primary-dummy features. In some examples, holes or slits can be formed in the Vcom layer at areas of the supplementary-dummy features to further improve visual uniformity.

  • Patent number: 10019090
    Abstract: A display may have an array of pixels. A transparent conductive layer may serve as a common voltage electrode layer and may distribute a common voltage to each of the pixels. Metal layers may be used to form routing structures. One of the metal layers may be patterned to form gate lines that distribute control signals to thin-film transistors in the pixels. Touch sensor circuitry may be coupled to horizontal and vertical capacitive touch sensor electrodes formed from the transparent conductive layer. A touch sensor signal border routing path in an inactive area of the display may have openings that run parallel to the gate lines and that each overlap one of the gate lines to reduce capacitive coupling between the gate lines and the touch sensor signal border routing path.

  • Patent number: 9979527
    Abstract: A communications apparatus includes a radio transceiver and a processor. The radio transceiver receives a plurality of feedback messages from a peer device. The feedback messages are transmitted by the peer device to indicate a result of UL data transmission. The processor analyzes content of the feedback messages to determine a preferred retransmission type of the peer device and records the preferred retransmission type of the peer device in a memory device. When the radio transceiver receives a first UL grant message indicating transmission of a first UL data and the processor determines that a forthcoming first feedback message corresponding to the transmission of the first UL data is unable to be received, the processor determines whether to retransmit the first UL data according to the preferred retransmission type of the peer device.
