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.

Disclosed are devices and methods for a display of an electronic device, the display including a backlight and a conductive layer, wherein the backlight illuminates both a main display and morphable keys or indicators. The conductive layer includes two separate portions. One portion of the conductive layer is part of a main display. The second portion, the non-main display region of the conductive layer includes at least one shutter configured to allow light from the backlight to pass therethrough and configured to block light from the backlight from passing therethrough. Accordingly, the shutter in part forms a morphable or smart key, or indicator that is illuminated by the backlight that illuminates the main display. In this way, separate LEDs to illuminate a morphable or smart key or indicator are not utilized.

Disclosed herein are a plurality of displays for an electronic device including a display layer (102, 104), a light guide layer (108), and a damping material layer (110) coupled between the light guide layer and the display layer. The display layer in one embodiment is a liquid crystal display layer, but other types of display layers may be used. The light guide layer may serve as a back light for the display layer, and may be between approximately 0.05 mm and 2 mm in thickness. Devices described herein include at least one interposed layer of acoustic and/or mechanical energy absorbing material, also referred to herein as damping material, between the display layer susceptible to vibration, and a hard layer near the display layer. The damping material as described herein may reduce the audio noise. The energy absorbing layer may take the form of an audio energy absorbing sheet interposed between layers of the display.

In a method of controlling a lighting unit of a display, a maximum value of ambient light intensity is determined (156). Ambient light intensity is sensed (154) from a first direction relative to the display and from a second direction, different from the first direction, relative to the display. The lighting unit is driven so that light from the lighting unit has a low intensity (172) when the maximum value is less than a first intensity threshold and so that light from the lighting unit has a high intensity, greater than the low intensity, when the maximum value is greater than a second intensity threshold.
摘要:
An electronic device having a video circuit for driving a display (100), the video circuit comprising one or more working registers (240) and a reset circuit (220, 230). The working register or registers (240) store video parameters of the display (100) and, optionally, the video circuit may be associated with one or more video synchronization signal (210). The reset circuit (220, 230) receives a periodic signal, such as the video synchronization signal or signals (210), and provides predetermined video parameters to the working register or registers (240) of the video circuit in response to receiving the periodic signal.
