    Abstract: 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.

    Abstract: This relates to a force-sensitive touch screen including a metallization layer for force sensing. In some examples, the force-sensing metallization layer can be deposited between a color filter layer and a thin film transistor (TFT) layer (including an array of TFTs) of the touch screen. In some examples, the metallization layer can be electrically coupled to a patterned conductive layer. Together, a force-sensing metallization trace of the metallization layer and a patterned conductor of the patterned conductive layer can act as a force sensor. Additionally or alternatively, the device can include a force-sensing metallization layer and a conductive layer (patterned or not) located beneath the TFT layer (i.e., rather than between a color filter layer and the TFT layer).

    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.

    Abstract translation: 提供了一体化触摸屏显示器的视觉均匀性的改进。 触摸屏可以包括由Vcom层中的间隙分开的公共电极。 为了改善由间隙引起的显示器的视觉不均匀性，可以在间隙的位置处的第二层上形成第一组半透明虚拟特征（初级虚拟特征），并且第二组虚拟特征 （辅助虚拟特征）也可以形成在第二层或另一层上以减轻初级虚拟特征的低空间分辨率和/或主要虚拟特征的非均匀间隔。 在一些示例中，可以在Vcom层中在辅助虚拟特征的区域处形成孔或狭缝，以进一步改善视觉均匀性。

    Abstract: A touch screen having touch circuitry integrated into a display pixel stackup. The touch screen can include a transistor layer, an LED layer and a first layer. The first layer can operate as an LED cathode during a display phase and as touch circuitry during a touch sensing phase. The transistor layer can be at least partially utilized for transitioning between the display phase and the touch sensing phase. The touch screen can be fabricated to reduce or eliminate damage to the LED layer.
