  • Patent number: 9298309
    Abstract: Various embodiments enable driving one or more sub-pixels with a source voltage while concurrently modulating the voltage of one or more common electrodes coupled to the sub-pixels to perform input sensing with the common electrodes. The voltage driven onto the sub-pixel may be shifted while the common electrode is modulated by a value about equal to about the amplitude of the modulation applied to the common electrode. Thus, the potential difference between the source line and common electrode remains substantially unchanged so that display asperities are not introduced while input sensing while concurrently updating a sub-pixel with display information. Thus, the common electrode(s) may be modulated for input sensing without interfering with display updating of the one or more sub-pixels, greatly increasing the amount of time available for performing input sensing and/or display updating.

  • Patent number: 9122336
    Abstract: A conductive electrode structure includes a substrate layer; at least one adhesion layer formed on the substrate layer for forming a circuit pattern; a conductive electrode layer formed on the adhesion layer for forming a conducting circuit corresponding to the circuit pattern; a first blackened layer formed on the conductive electrode layer corresponding to the circuit pattern and manufactured with an easily etched material; and a weatherproof layer formed on the first blackened layer and manufactured with an etch-resistant material. The weatherproof layer has a thickness smaller than the first blackened layer. The first blackened layer has a dark color for absorbing and stopping light from entering into the conductive electrode layer, and accordingly forms a shielding surface that prevents the conductive electrode layer from being directly visually perceived by a user. The conductive electrode structure also avoids side etching of the conductive electrode layer to ensure increased yield rate.
