Abstract: A method of directing a viewer's attention in an image display to enhance the perceived image quality and thus the viewer's preference of the image is disclosed. An image with an area of interest (AOI) is provided. The AOI is briefly displayed for a first time period. Subsequently, the image is normally displayed in its entirety for a second time period that is longer than the first time period. As a result, the viewer's attention is involuntarily directed to the AOI in a subliminal manner.

Abstract: An illuminant electric fan mainly comprises a base frame, a fan blade assembly and a plurality of LED lamps, in which the fan blade of the fan blade assembly is mounted and rotates in the tunnel bracket of the base frame to achieve air convection and heat dissipation. The fan blade is made of the luminous material to affect the luminance. Around the rim of the fan tunnel is decorated with a plurality of insert holes to be filled with the LED lamps too. The LED lamps are linked in series to a PCB, which serves the power supply and control over the rotation of the electric fan blade and the lighting of the LED lamps. The light beam emitted from the LED lamp will refract and radiate to produce a wonderful vision.
