Adjustment system and method for display device in optical module

Abstract

The invention provides an adjustment system and method for a display device in an optical module; the system is provided with an alignment clamp on a reference position and used for clamping a lens ora lens assembly, an adjusting mechanism is used for adjusting the position of a display panel, and the image acquisition device is used for shooting an alignment image of the display panel. The center offset and the angle offset of the actual position and the target position corresponding to the alignment image of the display panel are obtained, the position of the display panel is adjusted through the adjusting mechanism, and therefore the display panel is fixed to the lens or the lens assembly according to the design requirement. By arranging the reference position for clamping the lens orthe lens assembly, the lens or the lens assembly does not need to be calibrated, a temporary fixing mechanism does not need to be assembled and disassembled, only the position of the display panel needs to be adjusted, operation steps are simplified, and assembling and adjusting efficiency is improved; the operating arm of the adjusting mechanism is of a telescopic structure and is provided with an elastic end, so that the production cost and the operation complexity of the tool are simplified, the adjustment precision is improved, and the mass production requirement is met.

Description

technical field [0001] The invention relates to a technology for installing and adjusting optical components in an optical module, in particular to a system and method for installing and adjusting a display device in an optical module. Background technique [0002] Modern computer technology, display technology, sensor technology and other scientific technologies have promoted the development of AR (Augmented Reality, referred to as Augmented Reality) and VR (Virtual Reality, referred to as Virtual Reality) experience systems. VR scenes create a multi-dimensional information space. The virtual information environment enables users to have an immersive sense of immersion and has a perfect interaction ability with the environment; the AR scene applies virtual information to the real world, and the real environment and the virtual environment are superimposed on the same screen or space in real time simultaneously exist. [0003] The principle of AR and VR display devices is t...

Problems solved by technology

[0005] At present, the assembly process and tools for display devices in optical modules in the AR and VR industries are not perfect. figure 1 As shown in the display device 03, the traditional assembly and adjustment process usually uses an alignment instrument to first align and debug the light-emitting surface of the opaque display panel 031, and the display panel 031 needs to be characterized on the surface, and the display panel 031 needs to be temporarily Fix; then align and debug the lens or lens assembly so that the optical axis of the lens or lens assembly coincides with the center of the display area of ​​the display panel 031. In this way, manual or other special mechanisms are required to adjust the position of the lens or lens assembly, which increases the production cost; moreover, this method of assembly and adjustment requires two alignment operations, and the temporary fixing mechanism needs to be disassembled, resulting in low work efficiency and increased time Cost, not suitable for assembly and production of mass display devices
