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

Various examples of a lighting component and lighting device are described. In one aspect, a lighting component includes a supporting base and a LED die set. The supporting base includes a supporting surface and the LED die set includes at least four LED dies disposed on the supporting surface in a predefined arrangement. In another aspect, a lighting device includes a plurality of lighting components as described above that are arranged in a matrix. Therefore, each LED die of each lighting component defines a pixel, and can jointly define another pixel with one or more neighboring LED dies of one or more neighboring lighting components. Pixel pitch between pixels can thus be 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] Such as 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.
