Embodiment Construction

[0027] The invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] 1 to 5 show a glasses-type display in a preferred embodiment of the present invention.

[0029] As shown in Figures 1 to 2, the glasses-type display of the present invention is composed of a microdisplay chip 1, an optical prism 2, a focus adjustment mechanism 3, a display control circuit 4, a VGA interface 5, and a glasses mechanism 6. Micro-display chip 1 is a micro-display chip of OLED material, which belongs to an active light-emitting device. Its field of view is larger than that of a TFT micro-display chip, up to 120 degrees, which provides a larger virtual visual image for the design. offers the possibility. In addition, the frame refresh rate of the OLED microdisplay chip 1 can be as high as 120 Hz, so it provides convenience for realizing 3D visual images. Because the present invention adopts OLED microdisplay chip 1, and the viewing angle o...

Abstract

The present invention relates to a spectacle type display device which is composed of a micro-display device chip, an optical prism and a display device control circuit. The micro-display device chip is a made of OLED material, the image light emitted by the micro-display device is introduced to the optical prism through a transmission surface. The display device control circuit provides various required logic control signal for the micro-display device. The micro-display device of the invention is made of OLED material, its vision field angle can reach 120 degrees, the frame fresh rate can reach 120 Hz, and the display device can generate vision effect of big screen and can generate stereo vision effect. The invention adopts VGA interface compatible with VESA standard, and can be connected to any video apparatus having VGA interface. The invention also has focusing function and can be used by short sighted human. The second curved surface and the third curved surface of the optical prism of the invention are both ball surfaces, so the design and manufacturing method is simple and useful.

Description

technical field [0001] The invention 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 obtain stereoscopi...
