Embodiment Construction

[0027] The invention will be described in detail below with reference to the drawings and embodiments: Fig. 1 to Fig. 4 show a glasses-type display module in a preferred embodiment of the present invention.

[0028] As shown in FIGS. 1 and 2 , the glasses-type display module of the present invention is composed of a microdisplay chip 1 , an optical prism 2 , a focus adjustment mechanism 3 , and a display control circuit 4 . Because the radius of curvature R2 of the curved surface 22 of the prism 2 of the present invention is larger than the radius of curvature R3 of the curved surface 23, the radius of curvature of R2 is 140-180 mm, and the radius of curvature of R3 is 60-80 mm. After the two curved surfaces intersect, the angle between the two tangent lines at this point is 24°~45°. Adjusting the angle can adjust the thickness of the prism and the size of the object scene. Adjust the ratio of R3 / R2, roughly adjust the magnification of the image, and produce a visual effect of...

Abstract

The present invention relates to a novel spectacles type display which comprises micro-display chips, optical prisms, a display control circuit, etc. Two identical micro-display chips are cooperated with two optical prisms to form a binocular spectacles type display; the micro-display chips and the optical prisms respectively form a left-eye display and a right-eye display; the left-eye display and the right-eye display have symmetrical spatial locations; the distance between centers of the left-eye display and the right-eye display is between 63 mm and 65 mm; the inverted extension lines of normals of image surfaces of two displays intersect in the two-meter-place. The optical prism has three surfaces: a plane, a spherical surface and a free curved surface. Three surfaces of the optical prism of the invention only have a non-standard curved surface in order that the design, adjustment and manufacturing methods are simple and feasible. The invention adopts an AV port and a VGA port compatible with VESA standard and can link to any video equipment with the AV port and the VGA port. The invention also has the function of focusing for myopes to use.

Description

technical field [0001] The present invention mainly relates to a display, in particular to a glasses-type display. Background technique [0002] Good glasses-like display with small, thin, light geometry, sharp image, wide field of view, large pupil and virtual image with depth of field. [0003] The eye-Treck product of OLYMPUS company adopts TFT microdisplay chip, but because TFT microdisplay chip makes device produce transmitted light by backlight, its field of view has only 20 degrees, so the patent US.6,522,474 (Cobb; Joshua M. et al,) believed that the eye-Treck product of OLYMPUS Company was not suitable for stereoscopic 3D image display due to the small viewing area, and proposed a large viewing area scheme using spherical light. However, this solution requires a large space and can only be used in a helmet-mounted display. [0004] For this reason, US.6,034,717 (Dentinger et al.) and US.4,021,846 (Roese) provide a kind of binocular electronic shutter method to obt...
