Transmission type glasses displayer

Abstract

The invention relates to displaying equipment, in particular to a transmission type glasses displayer. The shortcoming that a transmission type glasses displayer of an existing reflecting waveguide device is low in light energy using rate, waveguide thickness is too large, and wearing is not comfortable is overcome. Part of a reflecting film in which the optical wave band where incidence images are placed is high in reflectivity and other wave bands are low in reflectivity is used as a reflecting device, a structure composed of a light guiding plate, an incidence reflecting device arranged in the light guiding plate and at least one displaying reflecting device is formed, and the structure is used for the fact that the incidence images are reflected by the incidence reflecting device and then are transmitted in a total-reflection mode between two parallel faces on the inner side of the light guiding plate, and the incidence images are subjected to emergence displaying after being reflected at the at least one displaying reflecting device. The light energy using rate of the glasses displayer can be improved, optical performance is stable, meanwhile, the structure is compact, and the whole weight of a system is lowered.

Description

technical field [0001] The invention relates to a display device, in particular to a see-through glasses display. Background technique [0002] A head-mounted display is an image display device worn on the head, and is usually placed on the user's head with a hat, a helmet, or a spectacle frame as a support. It mainly consists of four parts: image information display source, circuit control system, optical imaging system, and fixed support structure. It uses an optical system to project the image emitted by the microdisplay in front of people's eyes, forming a magnified virtual image. Head-mounted displays are new products in modern portable mobile display devices, and are widely used in image display of augmented reality, virtual reality, and stereoscopic display. [0003] As the most portable new type of wearable display device among head-mounted displays, glasses displays can be used not only in military affairs, but also in industry, medical treatment and daily life, e...

Problems solved by technology

On the one hand, such a structure has a low light energy utilization rate due to the use of a semi-transparent and semi-reflective film. On the other hand, the size of the reflective device is proportional to the field of view and the moving frame of the eye, which will force the thickness of the waveguide to increase, making the entire device The quality and volume of the product are increased, and it is uncomfortable to wear
