成果简介	NOVELTY - The module has tetrahedral prismatic element (2). A light source based on LEDs (1) is located on the front side face (4) of the prismatic element, a polarization-type beam-splitting element (7), and a microdisplay (8). The light source based on LEDs is designed in such a way that the LEDs are arranged symmetrically relative to the optical axis. The bases (3,5) of the prismatic element are made with a mirror coating completely. The rear side face (6) of the prismatic element is made transparent. The front side face of the prismatic element is made with a mirror coating in the zones which are not a projection of the LED surface. The rear side face of the prismatic element additionally contains a light-diffusing element. USE - Display backlight module for augmented reality system. ADVANTAGE - The improvement in the uniformity of illumination of microdisplays used in augmented reality systems is achieved. The number of LEDs, nomenclature and brightness parameters and location are selected based on the configuration of the prismatic element and the requirements for the uniformity coefficient of illumination. The polarized radiation flow is entered into the microdisplay, so that uniform illumination is ensured. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the display backlight module for augmented reality system. 1LED 2Tetrahedral prismatic element 3,5Bases of the prismatic element 4Front side face 6Rear side face of prismatic element 7Polarization-type beam-splitting element 8Microdisplay
