Embodiment 1

[0029] In this embodiment, the LED lamp bead 12 in the LED display screen is in an achromatic state when the screen is off, that is, the LED lamp bead 12 is black, white or gray in the off-screen state as an example for illustration.

[0030] refer to Figure 1-Figure 5 , the LED lamp bead 2 includes a packaging holder 120 with a cup, an LED chip 121 solidly embedded in the cup of the packaging holder 120, and a transparent packaging glue 122 covering the LED chip 121, that is, the LED lamp bead in this embodiment It is an SMD type lamp bead. In order to realize that the LED lamp bead 12 can display at least two different colors in the off-screen state (that is, the LED chip 121 in the packaging bracket 120 is in a state of not emitting light), the method adopted in this embodiment is to make the packaging bracket 120 There are at least two colors on the top surface and the outer peripheral surface.

[0031] In this embodiment, the description will be made by taking the LED ...

Embodiment 2

[0039] In the embodiment, the LED lamp beads 22 in the LED display screen are colored when the screen is off, that is, the LED lamp beads 22 are red, yellow, green, blue and other colors when the screen is off.

[0040] refer to Figure 6-Figure 7 , the LED lamp bead 22 includes a flat packaging bracket 220, an LED chip 221 solidly mounted on the packaging bracket 220, and a transparent packaging glue 222 covering the LED chip 221, that is, the LED lamp bead in this embodiment is a chip type lamp bead, wherein the LED chips 221 on each packaging bracket 220 include R, G, and B chips respectively.

[0041] In order to realize that the LED lamp bead 22 can display at least two different colors in the off-screen state (that is, the LED chip 221 in the packaging bracket 220 is in a state of not emitting light), the method adopted in this embodiment is to use a transparent packaging glue The toner of corresponding color is mixed in 222.

[0042] like Figure 7 As shown, the LED ...

Abstract

The invention relates to an LED display screen, which comprises a base and a plurality of LED lamp beads distributed on the base in an array mode. In a screen-off state, the LED lamp beads at least comprise a plurality of first lamp beads with a first color and a plurality of second lamp beads with a second color, and the first lamp beads and the second lamp beads are arrayed on the base accordingto a specific rule to form a specific pattern. Therefore, the problem that an existing LED screen cannot display a pattern in a screen-off state is solved.

Description

technical field [0001] The invention relates to the field of display screens, in particular to an LED display screen. Background technique [0002] Due to the advantages of high-definition display, high brightness, low power consumption, and long service life, LED display screens are widely used in indoor and outdoor places. The existing LED display screen uses a certain number of LED lamp beads arranged in a matrix form to form a matrix display unit. Each individual LED lamp bead is used as a pixel point. When working, each LED lamp bead according to the design A certain program emits light with a certain frequency, color, and brightness to form a corresponding image. [0003] However, the existing LED display screens generally do not work around the clock, and the working time is limited every day, and they do not display images when the screen is off, which occupies a limited display space. Moreover, in the off-screen state, the screen is usually black or black-gray, wh...
