Problems solved by technology

Since the LCD itself does not emit light, the LCD needs to use the lighting system to convey the image to the human eye. This lighting method is backlight lighting; but in the TFT-PGU system, the LCD screen is often caused by the small divergence angle of the fly-eye lens. The center area is brighter and the edge area is less bright or cannot be illuminated

Abstract

The invention provides a fly's-eye lens, a backlight illumination system, a method of manufacturing a fly's-eye lens, and a method of forming a backlight illumination system. The fly-eye lens comprises a substrate made of a light-transmitting material, the substrate is provided with a front side face for receiving light and a back side face opposite to the front side face, and the fly eye lens is characterized in that micro-unit lens arrays are arranged on the front side face and the back side face to adjust the emergent angle of a light beam incident to the front side face so that the light beam can be emitted from the back side face, wherein each micro-unit lens array includes a plurality of first micro-unit lenses and a plurality of second micro-unit lenses, the first micro-unit lenses having a different structure from the second micro-unit lenses.

Description

technical field [0001] The present application relates to the fields of optical elements and optical lighting, and more specifically, to a fly-eye lens, a backlight lighting system, a method for manufacturing the fly-eye lens, and a method for forming a backlight lighting system. Background technique [0002] The fly-eye lens is formed by a series of small lenses. Applying the double-row fly-eye lens array to the backlighting system can obtain higher light energy utilization efficiency and uniform illumination of a larger area. However, the small lenses in the traditional fly-eye lens all adopt the same structure, which is not conducive to improving the utilization rate of illumination light. [0003] With the continuous development of safe driving technology, the vehicle-mounted HUD (Head up Display; head-up display system) has been widely used. The purpose of the HUD optical system is to present a virtual display for the driver at a viewing distance of several meters in f...
