摘要:
Techniques are disclosed for lighting displays such as those associated with electrophoretic display (EPD) devices such as e-readers or any other display technologies or applications. In an embodiment, an EPD device is provided with a number of internal LEDs or other suitable light source generally disposed along at least a portion of the display perimeter. The light can be activated in situations where the available ambient light is inadequate for viewing the display. Light from the light source is distributed across the display, and in some embodiments can be adjusted to provide a desired degree of brightness. The light can be turned on or off via an existing single press-button or otherwise tactile, physical user interface that serves multiple functions. This user interface can be readily found and engaged by the user without the benefit of sight.
