Abstract: A portable electronic device with a touch illumination function and a touch illumination method thereof are provided. The portable electronic device with the touch illumination function includes an input module, a touch sensor, and an illumination module. The touch sensor is disposed around the input module, senses a touch motion of the input module, and generates a touch signal according to the touch motion. The illumination module is disposed around the input module, coupled with the touch sensor, and controls the illumination module to generate a light source to illuminate the input module according to the touch signal.

Abstract: To perform palm rejection, scan a plurality of areas on a touch panel to detect a plurality of triggered areas within the plurality of areas. Then detect which of the triggered areas are next to one another to determine a plurality of blocks. If the plurality of blocks contain a block with an overlarge area, then eliminate the block with the overlarge area, and generate a current coordinate according to a block with a smaller area which may be triggered by a finger or stylus.

Abstract: When a user moves an electromagnetic stylus to a capacitive touch panel, a transceiving winding will detect the frequency of the capacitive touch panel. A synchronizing winding will oscillate to generate a signal having a frequency similar to that of the capacitive touch panel. An oscillator will amplify the signal generated by the synchronizing winding. A circuit board will process the signal amplified by the oscillator. Finally the transceiving winding will emit a wireless signal with a frequency similar to that of the capacitive touch panel to interfere with the electric (magnetic) field of the capacitive touch panel so as to detect a triggered coordinate of the capacitive touch panel.

Abstract: A patterning method is provided. First, a substrate having an objective material layer thereon is provided. Thereafter, a mask layer is formed on the objective material layer. Afterwards, a patterned layer is formed over the mask layer, wherein a material of the patterned layer includes a metal-containing substance. Then, the mask layer is patterned to form a patterned mask layer. Further, the objective material layer is patterned, using the patterned mask layer as a mask.
