Invisible light is emitted from a screen of a display portion. The invisible light reflected from a target object which comes in contact with or close to the screen is received on the screen. On the basis of the received invisible light, the target object is detected. Thus, the target object can be reliably detected without influence of the display state of the display portion, and influence of use conditions such as surrounding circumstances (the case where it is bright or dark). Moreover, for example, it is not necessary to separately arrange a component such as a touch panel, so the image display unit can be achieved with a simple structure.

Particular implementations of the subject matter described in this specification can be implemented so as to realize one or more of the following optional advantages. The sharing of the drive lines may allow for a screen sized or otherwise configured to have more measurement nodes than would be produced by the sum of the nodes that could be measured by the individual devices. For a screen that requires multiple measurement devices, the drive line sharing thus may allow use of a smaller number of measuring devices.

  • Patent number: 8860696
    Abstract: An integrated touch-sensing display is operated to detect the location of one or more objects on a touch surface. The integrated touch-sensing display defines a display area. A light guide (14) is arranged over the display area to define the touch surface (16). The light guide (14) is illuminated internally such that an object (20) contacting the touch surface (16) causes part of the illuminating light to be scattered towards the display area. An array of light sensors (6) is integrated within the display area to detect the scattered light. Based on output signals from the light sensors (6), a processing element obtains image data that represents the light that impinges on the display area excluding ambient light, and determines the location of the object (20) on the touch surface (16). Ambient light may be suppressed by a spectral passband filter in front of each light sensor (6), and/or by electronic filtering of the output signals from the sensors (6).

  • Patent number: 8836665
    Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user is likely to have intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The learning function is disabled, however, when the relevant words are found to be in a special category for which frequency learning, i.e., frequency revision, is not employed.

    Abstract: A touch apparatus includes a touch panel, voltage storage elements, a voltage supply unit, and a processing unit. The touch panel has electrodes respectively coupled to the voltage storage elements. When the voltage supply unit does not provide the voltage to the voltage storage element, the voltage storage element achieves a voltage balance within an energy storage time and stores a voltage of the corresponding electrode. The energy storage times of a part of the voltage storage elements at least partially overlap. The energy storage times of two the voltage storage elements respectively coupled to two adjacent electrodes do not overlap with each other. The processing unit is coupled to the electrodes and the voltage storage elements and adopts voltages stored in the voltage storage elements when the voltage balance is achieved.
