Abstract

The invention relates to an LED lamp bead capable of improving a display effect and an LED display screen. The lamp bead comprises a lamp body, a primary color light-emitting device, an ultraviolet LED chip, pins and a packaging layer, wherein the primary color light-emitting device and the ultraviolet LED chip are arranged on the lamp body, and the packaging layer packages the primary color light-emitting device and the ultraviolet LED chip on the lamp body; the primary color light-emitting device and the ultraviolet LED chip are electrically connected with the pins; the packaging layer comprises a photochromic material, and when the ultraviolet LED chip does not emit light, the packaging layer is transparent; when the ultraviolet LED chip emits ultraviolet light, the photochromic material absorbs the ultraviolet light and becomes black, and the packaging layer becomes black gradually. The photochromic material is transparent, the packaging layer has good light emitting efficiency, the light emitting brightness can be improved without increasing the size and current of the light emitting device, the power consumption is low, and the problem of temperature rise does not exist; thelight emitting intensity of the ultraviolet LED chip is controlled, the blackening degree of the packaging layer can be controlled, the contrast ratio is controlled, and the display effect is improved.

Description

technical field [0001] The invention relates to the field of LED display, in particular to an LED lamp bead and an LED display screen for improving the display effect. Background technique [0002] LED has the characteristics of low energy consumption, high brightness, and high refresh rate, and is widely used in display, lighting, backlight and other fields. Among them, LED displays are more and more widely used, including command centers, video conference rooms, studios, shopping malls and other indoor places, as well as outdoor large-screen displays. The requirements for display effects, such as contrast, brightness, and resolution, are also increasing. higher. There are many factors that affect the display effect, but LED lamp beads are the basic factors that determine the display effect. [0003] At present, LED displays generally use LED lamp beads with SMD package structure. Generally, LED chips are fixed on the substrate, and then the entire surface of the substrat...
