Abstract:

In order to solve a common problem of vision drop in teenagers, we design an intelligent instrument for improving vision, which is based on the Physiological characteristics of the eye. The instrument applies computer control technology and dual color LED (Light Emitting Diode) display technology, and uses stm32f103zet6 microprocessor to control LED display screen and man-machine system, and uses RLE(Run Length Encoding) image compression technology to make display flexible, rich and colorful. The tester uses the operating platform (voice prompts and liquid crystal display) to observe various types of training graphics, which can adjust the tension of the eye and relieve vision fatigue. After a period of treatment, the test results show that the students‘ eyesight is generally improved, and the effect is remarkable.

Key words: light emitting diode ( LED ) screen, computer control, image compression technology, improve eyesight
