  • Patent number: 8482500
    Abstract: In a display apparatus, a text code input section outputs externally-supplied text code information to a font conversion section and a voice synthesizer section. The font conversion section converts the input text code into a corresponding font, and transmits the font to a display drive section via a video signal input section, and the display drive section causes a display section to display the font. Meanwhile, the voice synthesizer section converts the input text code into corresponding voice data, and transmits the voice data to a voice device where the voice data is outputted. With this structure, superior convenience is ensured for a display apparatus which serves only as an individual displaying apparatus and relies on an external device (server) for the major functions of the system.

  • Patent number: 8482544
    Abstract: Negative pixel compensation in a touch sensitive device is disclosed. The device can compensate for a negative pixel effect in touch signal outputs due to poor grounding of an object touching the device. To do so, the device can switch to a configuration to measure the grounding condition of the touching object and use the measurement to compensate the touch output values from the device accordingly. In the switched configuration, a first set of lines of the device can be switched between a coupling to a stimulation signal input to drive the device, a coupling to a capacitance signal output to output a signal indicative of the object's grounding condition, and a coupling to ground. A second set of lines of the device can be coupled to a touch signal output to output a signal indicative of the object's touch at the device. In addition or alternatively, in the switched configuration, the first set of lines of the device can be switched to function as the second set of lines and vice versa.
