发明名称 TWINKLE EFFECT DISPLAY SYSTEM IN WHICH INFORMATION IS MODULATED AT A RATE WITHIN THE FLICKER FREQUENCY OF THE HUMAN EYE
摘要 A twinkle effect display system comprises a display device, the intensity input of which is amplitude modulated at a rate within the usable flicker frequency band of the human eye. The modulation may be either symmetrical or asymmetrical and may be either continuous or in steps; and the index of modulation may range from one hundred percent to appreciably lower values which still provide a readily observable twinkling.
