摘要： Apparatuses and methods are provided for housing electrical components (312) of an electronic device in an enclosure (300) with an integrated backlight for a liquid crystal display (LCD) of the electronic device. An enclosure comprises a back plate (306), with a plurality of light sources (308) coupled to the back plate. The light sources provide back light for the LCD. The enclosure also comprises a plurality of spacers (310) which are coupled to a diffuser (304) of the LCD. Each spacer is adapted to optically couple to a corresponding light source to transmit light from the light source to the diffuser. The spacers are also adapted to secure electrical components in place between multiple spacers. Thus, non-display electrical components (1202) and display components may be housed within a single enclosure, which results in a significantly thinner device than prior art devices utilizing compartmentalized LCD displays.

摘要： Apparatuses and methods are provided for determining coordinates of simultaneous touches on a touch sensor pad. A touch sensor pad includes a first plurality of resistive sensor strips on a first resistive sheet and a second plurality of resistive sensor strips on a second resistive sheet. A user touches the touch sensor pad at multiple locations simultaneously. A controller of the touch sensor pad determines coordinates of each of the multiple locations of touch independently of other touches. To determine coordinates for a touch, the controller identifies a first strip of the first plurality of resistive sensor strips of the first resistive sheet making contact with a second strip of the second plurality of resistive sensor strips of the second resistive sheet in response to the touch. The controller measures voltages of the strips to determine coordinates of the touch and measures resistance shifts in the strips due to touches to determine contact area of the touch which correlates to the types of objects causing the touch and the pressure of the touch.
