The gate driver circuitry has gate drivers that apply a control pulse to each of a number of gate lines in sequence, from a previous gate line to a current gate line, during a frame interval in which the array of display elements is filled with pixel values. Each gate driver has a latch stage followed by an output stage. The output stage is coupled to drive a current gate line, and the latch stage is coupled to drive a) a first hold circuit that holds the current gate line at a predetermined voltage, and b) a second hold circuit that holds a previous gate line at a predetermined voltage. Other embodiments are also described and claimed.

摘要： Methods and devices employing charge removal circuitry are provided to reduce or eliminate artifacts due to a bias voltage remaining on an electronic display after the display is turned off. In one example, a method may include connecting a pixel electrode of a display to ground through charge removal circuitry while the display is off (e.g., using depletion-mode transistors that are active when gates of the depletion-mode transistors are provided a ground voltage). When a corresponding common electrode is also connected to ground, a voltage difference between the pixel electrode and common electrode may be reduced or eliminated, preventing a bias voltage from causing display artifacts in the pixel.

摘要： A self-capacitive touch sensor panel configured to have a portion of both the touch and display functionality integrated into a common layer is provided. The touch sensor panel includes a layer with circuit elements that can switchably operate as both touch circuitry and display circuitry such that during a touch mode of the device the circuit elements operate as touch circuitry and during a display mode of the device the circuit elements operate as display circuitry. The touch mode and display mode can be time multiplexed. By integrating the touch hardware and display hardware into common layers, savings in power, weight and thickness of the device can be realized.

摘要： A touch screen is disclosed that includes conductive elements in a display area and connecting traces for routing the conductive elements to other locations. The connecting traces can be routed underneath or over existing opaque structures in the display area, instead of in border areas adjacent to the display area, to minimize the effect of the connecting traces on the display aperture ratio. The lengths and/or widths of these connecting traces as well as the number of parallel connecting traces used to connect to a particular element can be selected to balance the load on the drive and/or sense circuitry and on display pixels caused by the connecting traces.

摘要： 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.

摘要： A touch screen to reduce touch pixel coupling. In some examples, the touch screen can include a first display pixel and a second display pixel in a row of display pixels, where the first display pixel can be configurable to be decoupled from the second display pixel during at least a touch sensing phase of the touch screen. In some examples, the touch screen can include a display pixel having a first and a second transistor, where the second transistor can be electrically connected to a gate terminal of the first transistor, and can be diode-connected. In some examples, the touch screen can include two display pixels, each display pixel having two transistors, where two of the transistors can be electrically connected to a first gate line, and the remaining two transistors can be individually electrically connected to a second and third gate line, respectively.
