Embodiment Construction
[0035] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0036] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract
The invention relates to a light-emitting module and AR glasses. The light-emitting module comprises a substrate, a circuit layer, an insulating layer, light-emitting elements and an anti-oxidation layer; the substrate is used for providing support; the circuit layer is arranged on one side of the substrate; connecting pins are arranged on the circuit layer; the insulating layer covers the side, far away from the substrate, of the circuit layer; window areas are formed in the positions, corresponding to the connecting pins, of the insulating layer, so that the connecting pins are exposed outside the insulating layer; the light-emitting elements are electrically connected with the connecting pins; the anti-oxidation layer at least covers the connecting pins and the light-emitting elements in the window areas. According to the light-emitting module and AR glasses, the connecting pins of the window areas of the light-emitting module can be isolated from external air without dead angles; and therefore, the connecting pins, exposed at the insulating layer, of the window areas are prevented from being oxidized, the reliability of electrical connection between the light-emitting elementsand the connecting pins can be guaranteed, it is guaranteed that the light-emitting elements can emit light normally, and the reliability and accuracy of eyeball tracking of the camera of the AR glasses are improved.
Description
technical field [0001] The present invention relates to the technical field of light emitting modules, in particular to a light emitting module and AR glasses. Background technique [0002] Traditional light-emitting modules generally include a circuit layer, an insulating layer and a light-emitting element. The insulating layer covers the circuit layer to protect the circuit in the circuit layer. A window area is usually opened in the insulating layer, so that the circuit layer corresponding to the window area It is exposed outside the insulating layer to form a copper foot to be electrically connected with the light-emitting element. However, the copper feet exposed outside the insulating layer are easily oxidized by air, which leads to the failure of the electrical connection between the copper feet and the light-emitting element. Contents of the invention [0003] Based on this, it is necessary to provide a light-emitting module and AR glasses to solve the problem tha...
