摘要:
A magnetic field shielding layer that does not affect an operation of a geo-magnetic sensor in a pointing input device of a touch screen type using an electromagnetic pen is provided. A magnetic field shielding layer is composed of magnetic metal powder. The magnetic field shielding layer is formed directly on the pointing input device without a need for a separate adhesive layer.

Disclosed is an optical fiber illumination device including a light source for outputting light; a coupler for converging the light input from the light source through multiple reflection; and an optical fiber to which the converged light is input.
摘要:
A color electronic paper keypad device is provided that includes an electronic paper sheet having a plurality of electrode patterns. One or more of the plurality of electrode patterns displays a color depending on whether an electric field is applied. The device also includes a color display disposed over the electronic paper sheet. The color display changes the displayed color depending on whether a second electric field is applied. An illumination light reflects from or transmits through the color display to change the displayed color of the one or more electrode patterns. The device further includes a front light unit for illuminating said color display.
摘要:
A method and apparatus for driving an ElectroPhoretic Display (EPD) are provided, in which upon sensing a request for displaying data in a gradual graphic representation scheme, a plurality of segments for displaying the data are determined, a display changing order of the segments is determined, an inter-segment time interval is calculated, driving voltage pulses are applied to a first segment according to the display changing order, and driving voltage pulses are applied to each of the other segments at the inter-segment time interval after driving voltage pulses are applied to a previous segment according to the display changing order.
