A system for improving the vertical viewing angle color cast of 3dled special-shaped splicing screen

Abstract

The invention discloses a color cast system for improving the vertical viewing angle of a 3D LED special-shaped splicing screen, belonging to the technical field of 3D-LED stereoscopic display, comprising a carrier, a contact point cathode pad and a contact point anode pad, an LED chip unit, an independently controlled A light-emitting point and an LED package; the positive and negative electrodes of the LED chip unit are connected to the contact point cathode pad and the contact point anode pad in an orderly manner through electrode leads; the LED chip unit includes independently controlled light-emitting points, the light-emitting Points A1, A2 and A3 represent a light-emitting unit of the LED display; the LED package body includes a first LED chip unit, a second LED chip unit and a third LED chip unit distributed in an array. The present invention adopts the way of array arrangement of LED chip units, and each light-emitting unit is distributed in a stepped shape. During the process of 3D LED display seaming, since there are red, green and blue light emitting points in the horizontal and vertical directions, the seam will not be Blue light or yellow light appears, which solves the color cast problem of 3D LED with large viewing angle.

Description

technical field [0001] The invention belongs to the technical field of 3D-LED stereoscopic display, and in particular relates to a system for improving the vertical viewing angle color cast of a 3D LED special-shaped splicing screen. Background technique [0002] LED display has the advantages of wide color gamut, high brightness, low power consumption and long life. The current mainstream polarized 3D display technology is introduced in 3D cinema, 3D smart education, 3D surgery live broadcast, VR / AR, science and technology exhibition halls, urban geography Information and other fields have a broad market space. With the continuous enrichment of 3DLED application scenarios, LEDs are developing in the direction of Micro-LED technology. The size of LED chips is getting smaller and even miniaturized, the pitch of 3D films is getting smaller and smaller, and the alignment accuracy is getting higher and higher. The technical difficulty of adapting to Micro-LED is also increasing...
