    摘要: A system and method for compensating for non-uniform illumination from a light guide for a display in an electronics device is provided. The system comprises: a memory device storing a data representing a first compensation pattern for generation on the display to block light from a first portion of the light guide relative to light from a second portion of the light guide; a first module to incorporate the stored representation into an image to be displayed on the display; and a second module to generate the image with the stored representation for display on the display. In the system, when the first module generates the first compensation pattern on the display, the first compensation pattern aligns with the first and second portions to reduce an intensity of light from a light source passing through the first compensation pattern from the first portion relative to an intensity of light passing through the first compensation pattern from the second portion from the light source.

    摘要: A handheld communications device and method for transmitting an encryption key are provided. The method comprises: generating an encryption key via the data processor, the encryption key comprising a bit sequence; and varying an output of the display device over a period of time to transmit the encryption key from the handheld communications device by varying at least one of a sequence at least one of colour rendered on the display device or a sequence of brightness levels output by the display device.
