Problems solved by technology

[0004] The main purpose of the present invention is to provide a light-emitting element, a lamp bead, a display device, and a packaging method for the light-emitting element, aiming to solve the problem of any one of the two-color chips due to the horizontal placement of the two-color B&G chips in the prior art. The lack of color phenomenon occurs on one side, resulting in technical problems of uneven color mixing and uneven color cast of the display device

Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative relationship between the components in a certain posture (as shown in the accompanying drawings). When the positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

Abstract

The invention discloses a light-emitting element, a lamp bead, a display device and a light-emitting element packaging method, and belongs to the technical field of LED chips. The light-emitting element comprises a circuit board; the first light-emitting chip is provided with a first surface and a second surface which are opposite to each other, the second surface is connected with the circuit board, and the second surface is provided with a first anode and a first cathode; and the second light-emitting chip is arranged below the first surface, and a second anode and a second cathode are arranged on the surface of one side, deviating from the first surface, of the second light-emitting chip. According to the invention, the double-color chip is arranged in a stacked manner instead of a horizontal manner, so that the problem of uneven color mixing and color cast of the double-color chip in the prior art is solved, the brightness of the double-color chip is ensured, the color mixing and color cast effects of the double-color chip are improved, and the color gamut is improved.

Description

technical field [0001] The invention relates to the technical field of LED chips, in particular to a light emitting element, a lamp bead, a display device and a packaging method for the light emitting element. Background technique [0002] In related technologies, LED manufacturers have introduced NTSC1931, a new type of two-color chip B&Gchips+R powder (blue-green light chip+red phosphor powder), whose color gamut value can reach 100-105%. [0003] However, the traditional two-color chip LED lamp beads have the problem of poor color mixing effect. Due to the difference in the position of the two-color B&G chip, the two-color chip B&G is generally placed horizontally, and then covered with phosphor powder. The light is decomposed into two parts after directional transmission through the optical lens. , green and magenta, and uniform white light cannot be obtained. Contents of the invention [0004] The main purpose of the present invention is to provide a light-emitting e...
