Abstract
The utility model relates to a portable light-emitting diode graphics context display unit which comprises a set of light-emitting diodes (LED) (8) and a drive circuit (7). The utility model is characterized in that the utility model is also provided with a single-chip microcomputer (4) connected to the drive circuit (7); the LEDs (8) are arranged in a single row. The portable light-emitting diode graphics context display unit refers to a portable display unit by using hands to sway the LED luminarie to generate bit shifts and using a visual persistence phenomenon to form an image. An electromechanical transducer is used to apperceive the motion law of the hands to control the illuminated time of the LEDs, and meanwhile, the operation of the software is used to compensate the motion irregularity of the hands to display stable images. Because the hands are adopted to replace a motor to drive the LEDs, weight, cost and power expenditure are reduced, and consequently, a battery can be adopted to supply power. In addition, because the visual persistence phenomenon is used, the number of the LEDs is reduced to make the utility model very portable and cheap.
Description
Technical field
