AI Technical Summary

Technical Problem

How to solve the assembly problems of Micro LED display panels and lenses, especially to achieve miniaturization and weight reduction of micro-projection optical engines in wearable electronic devices.

Method used

By electrically connecting the first microdisplay panel to at least two second microdisplay panels and arranging them around the light combining assembly, the distribution of electrical connection locations is achieved using a flexible circuit board. Combined with the design of the mounting frame and lens assembly, the space occupied by the electrical connections is reduced.

Benefits of technology

It effectively reduces the assembly volume of electronic devices and the size of micro-projection optical engines, improves the overall strength and durability of the equipment, and is suitable for miniaturized electronic devices.

Abstract

A display panel assembly structure, a micro-projector optical engine, and an electronic device. The display panel assembly structure comprises: a first micro-display panel (300), wherein the first micro-display panel (300) is provided with at least two first connector portions (3003), and different first connector portions (3003) are electrically connected by means of first electrical connection members (3002); and at least two second micro-display panels (400), wherein each second micro-display panel (400) is provided with a second connector portion (4003), and the at least two first connector portions (3003) of the first micro-display panel (300) can be electrically connected to corresponding second connector portions (4003) of the at least two second micro-display panels (400). At least two electrical connection positions formed by electrically connecting at least three micro-display panels (300, 400) can be distributed on different sides, so that the problem of occupying a large area by arranging multiple electrical connection positions on the same side can be avoided, thereby reducing the assembly volume of electronic devices and facilitating the miniaturization of electronic devices.
