Problems solved by technology

However, the pixel pitch of existing light-emitting devices can only be greater than or equal to the size (length or width) of the light-emitting element 9, and it is difficult to be smaller than the size of the light-emitting element 9; this is because one light-emitting element 9 can only constitute a single pixel P

Embodiment Construction

[0055] In order to make the above purpose, technical features and advantages more comprehensible, preferred embodiments are described below in detail with the accompanying drawings.

[0056] see Figure 2A Shown is a top view of the light emitting element according to the first preferred embodiment of the present invention. In the first embodiment of the present invention, a light emitting element 10 is proposed, and the light emitting element 10 may include a carrier 11 and an LED die group 12 .

[0057] The bearing base 11 can have a bearing surface 111, and the bearing surface 111 can have a plurality of separated electrodes 112 (or referred to as upper electrodes). The shape of the carrying surface 111 can be rectangular (such as a rectangle or a square), circular, elliptical, polygonal or irregular, etc., and in this embodiment, the carrying surface 111 is rectangular and also a square; in other words, the carrying surface The four sides of 111 are equal in length.

Abstract

The invention provides a light emitting element and a light emitting device. The light-emitting element includes a bearing seat and an LED crystal grain group, the bearing seat has a bearing surface, and the LED crystal grain group has at least four LED crystal grains. The LED chips are arranged on the carrying surface and arranged in a specific way. The light-emitting device includes a plurality of light-emitting elements mentioned above, and these light-emitting elements are arranged in a matrix. In this way, the LED dies of each light-emitting element can define a pixel by itself, and can also jointly define another pixel with the LED dies of adjacent light-emitting elements, so that the distance between pixels is reduced.

Description

technical field [0001] The invention relates to a light-emitting element and a light-emitting device, in particular to a light-emitting element and a light-emitting device including LED crystal grains. Background technique [0002] Among the existing light-emitting elements, more and more LED crystal grains are used as their light sources. For example, Figure 1A The light emitting element 9 shown uses three LED crystal grains 91 of different colors, so that the light emitting element 9 can emit light of three colors. [0003] like Figure 1B As shown, a plurality of such light-emitting elements 9 can be arranged to form a light-emitting device (such as electronic signage, display, etc.). Among the characteristics of the light emitting device, resolution is an important factor; when the resolution of the light emitting device is better, the picture or image displayed by the light emitting device will be more detailed, so that viewers have better visual experience.
