    摘要： A capacitive sensor (200) for a touch sensitive electronic device (800) includes at least one graphic (401) visible to a user. The graphic (401) is configured so as to be non-electrically interfering with the electrode array of the capacitive sensor (200). A substrate (101), configured to transmit light, has a layer of capacitive sensor material (201) deposited thereon. The layer of capacitive sensor material (201) is electrically conductive and pellucid. A layer of selectively disposed electrically conductive material (202) is then electrically coupled to the layer of capacitive sensor material (201). The layer of selectively disposed electrically conductive material (202) is arranged as a graphic, which may be a logo, brand, or other mark. The layer of selectively disposed electrically conductive material (202) has a reflectivity that is greater than the layer of capacitive sensor material (201) so as to make the graphic (401) visible to a user.

    摘要： A touchscreen display system (418) is provided which includes a touchscreen (420), a touchscreen input detector (422), a capacitive sensor driver (423), and a display driver (424). The touchscreen input detector (422) is coupled to a first layer (504) of the touchscreen (420) and determines a touchscreen (420) input in response to sensing tactile inputs during a sensing time interval (610). The display driver (424) is coupled to a second layer (506) of the touchscreen (420) and provides a drive voltage (606, 608) at a first voltage level to the plurality of optical shutter segments (508) during a first portion (620) of the sensing time interval (610) and maintains the drive voltage (606, 608) at substantially zero volts during a second portion (622) of the sensing time interval (610), the second portion (622) being greater than half of the sensing time interval (610).

    摘要： An electronic device is operable to determine a touch input applied to a capacitive touch panel system thereof so as to account for time-varying noise affecting the touch panel system. The electronic device includes the touch panel system, an analog-to-digital conversion (ADC) unit, and a processing unit. The processing unit is operable to: receive digital signal values from the ADC unit representing capacitances detected by sensing points of the touch panel system; adjust at least one of the digital signal values based at least on a time-varying noise to produce at least one noise-adjusted value; and determine the touch input based on the at least one noise-adjusted value. In one embodiment, the electronic device determines the time-varying noise prior to adjusting the digital signal values. In another embodiment, the time-varying noise is produced by a display panel of a touchscreen display that also includes the touch panel system.

    摘要： Disclosed are devices and methods for intradevice communication in a mobile communication device having a display. A method includes providing a supply signal and superimposing a data signal onto the supply signal. The method further includes driving a light source with the supply signal and the superimposed data signal to produce light to illuminate the display. Also included is sensing the light illuminating the display with an optical sensor, which is coupled to a receiver circuit, and then distinguishing the data signal from the sensed light with the receiver circuit. An image is formed on the display using the data signal distinguished with the receiver circuit.

The dielectric layer is formed as a thick layer from a ceramic material to provide:a dielectric strength greater than about 1.0.times.10.sup.6 V/m;a dielectric constant such that the ratio of the dielectric constant of the dielectric material to that of the phosphor layer is greater than about 50:1;a thickness such that the ratio of the thickness of the dielectric layer to that of the phosphor layer is in the range of about 20:1 to 500:1; anda surface adjacent the phosphor layer which is compatible with the phosphor layer and sufficiently smooth that the phosphor layer illuminates generally uniformly at a given excitation voltage.The invention also provides for electrical connection of an electroluminescent laminate to voltage driving circuity with through-hole technology. The invention also extends to laser scribing the transparent conductor lines of an electroluminescent laminate.
