Abstract

The invention discloses an efficient chromatic aberration eliminating LED display module which relates to the field of LED display. The invention solves the problem of influence of the display effect of an LED screen caused by that the light-emitting range of the traditional LED chip can not reach the range of a target view field and the edge part of the target view field generates chromatic aberration. The efficient chromatic aberration eliminating LED display module comprises three-color LEDs and a reflector, wherein the three-color LEDs are in linear arrangement; and a reflecting film is plated on the surface of the reflector which is parallel to the linear arrangement direction of the three-color LEDs. The LED display module of the invention improves the utilization ratio of energy and does not plate the film on the surface of the reflector which is perpendicular to the LEDs, thereby eliminating chromatic aberration.

Description

technical field [0001] The invention relates to the field of LED display, in particular to an LED display module for eliminating color difference. Background technique [0002] At present, in the field of LED large-screen display, there are two main problems that limit the development of the industry in terms of optics: [0003] 1. Energy limitation, that is, the brightness limitation of a single LED pixel. The main problem is that the target field of view is smaller than the light emitting range of the LED chip, which leads to the energy outside the field of view not reaching the target field of view, which leads to the failure of the entire system. Energy utilization decreases and power consumption increases. [0004] Second, the appearance of chromatic aberration, that is, because the chip unit of the color LED is composed of three primary color crystal elements, there will be chromatic aberration at the edge of the target field of view, and the chromatic aberration phen...
