CN203178580U - Screen-viewing glasses device for flat computer - Google Patents

Abstract

The utility model discloses screen-viewing glasses for a flat computer. The screen-viewing glasses are mainly used for watching side-by-side stereoscopic images displayed on the flat computer. Viewing lines of two eyes are stretched by two planar mirrors in the screen-viewing glasses. Eyepiece mirrors are positioned close to eyeballs as much as possible. An included angle between a center of the viewing lines and an eyepiece mirror is less than 45 degrees. A distance between an objective lens mirror and the eyepiece mirror is less than 28 mm. A distance between two centers of viewing lines of the two objective lens mirrors is less than 125mm, so that two viewing lines of the screen-viewing glasses face squarely to the left side and the right side images on the flat computer.

Description

The panel computer observation mirror

Technical field

The utility model relates to a kind of viewing apparatus of 3D image, especially a kind ofly watches the 3D film of left and right sides form or the viewing apparatus of 3D TV programme at the panel computer display screen.

Background technology

Gone out panel computer now, the panel computer screen is little, but pixel is not low, screen about 10 cun, the tool pixel has accomplished that 10 cun panel computer pixels of Google are up to 2560 * 1600, near the twice of full HD televisor than big televisor much higher pixel also, so on panel computer, appreciate the horizontal parallax stereopsis with observation mirror, also should equally can accomplish the stereopsis effect of seeing at big display or big televisor.But (patent No.: two sight lines of 200610062410.4,201120493103.8) finding out are wideer for observation mirror before, it is too many to surpass half width of panel computer screen, seeing particularly the small screen need closely be watched could obtain with the same visual field of giant-screen, so near the more difficult left and right sides two halves picture with sight line subtend the small screen of observation mirror of screen, so original observation mirror mode can't be seen stereopsis in the small screen.

Summary of the invention

In order on panel computer, also to enjoy stereopsis with observation mirror, observation mirror need shorten two object lens mirror pitch, because people's two eye pupils are apart from not dwindling, the spacing of observation mirror two eyepiece catoptrons is also little can dwindle, and the sight line that the two object lens catoptrons that spacing is dwindled are found out will be blocked by the eyepiece catoptron.In this case, at first need to reduce eyepiece catoptron area, for the area that reduces the eyepiece catoptron does not influence although the visual field that goes out, has only the eyepiece of allowing catoptron as far as possible near eyeball, also to reduce eyepiece catoptron and eyes simultaneously and find out angle (5) between the sight line, the object lens reflector position reach that sight line is turned to, after having dwindled eyeball and eyepiece catoptron distance, the fixing position of object lens catoptron has only reach, and object lens catoptron reach simultaneously also can reduce the scope of being blocked by the eyepiece catoptron.

The technical scheme that its technical matters that solves the utility model adopts is: the eyepiece catoptron is as far as possible near eyeball, the angle that eyepiece catoptron and eye center sight line form is less than 45 degree, the spacing at eyepiece catoptron and object lens catoptron central vision place is less than 28mm, and the central vision that two object lens catoptrons are found out goes out shell place spacing less than 125mm.

The beneficial effects of the utility model are: panel computer market is big, the use crowd is big, though screen is little, but pixel height, closely watch the visual field also to be equal to remote large display screen, appreciate stereopsis with observation mirror on such small display, add magnifier, visual effect can surpass large display screen.And panel computer is power-saving, appreciates more environmental protection of image at panel computer.

Description of drawings

The basic light path of Fig. 1 panel computer observation mirror;

1. eyepiece catoptrons among the figure, 2. object lens catoptron, 3. panel computer display screen, 4. the anti-other Jing Zhongxinshixianchu distance of eyeball and eyepiece, 5. eyepiece catoptron and eyes are found out the angle of central vision, 6. the eyepiece catoptron is to object lens catoptron central vision, and 7. observation mirror two is found out central vision spacing, 8. interpupillary distance.

Embodiment

1. the clear accompanying drawing in this Shen of light path designs at 10 cun panel computers, 10 cun wide about 220mm of screen; Near eyeball, less than 20mm (4), the accompanying drawing eyeball is apart from the eyepiece catoptron central vision about 13mm in place apart from eyepiece catoptron central vision place for its eyeball as far as possible for observation mirror eyepiece catoptron (1); The angle (5) that eyepiece catoptron and eye center sight line form is less than 45 degree, and accompanying drawing is 39 degree; The spacing (6) at eyepiece catoptron and object lens catoptron central vision place is less than 28mm, the about 23mm of accompanying drawing; The central vision that two object lens catoptrons are found out goes out shell place spacing less than 125mm (7), and accompanying drawing is 110mm, and sight line is over against the left and right sides two halves picture of screen.

2. put people's mirror because the panel computer screen is little, be to increase breadth, observation mirror can press close to screen 100-200 closely on watch owing to closely watch the normal range that has surpassed the eyes focal lengths, can add magnifier two light path.The picture element density height of panel computer (Google reaches 299ppi for 10 cun) can be watched with this magnifier that amplifies focal length fully.Magnifier can be added between eyeball and the eyepiece catoptron, also can be added in observation mirror and find out the window place.

3. symmetrical sight line is adjusted to and makes this device can adapt to the flat plates with different sizes computer, even compatible display, television screen, and this observation mirror has still used symmetrical governor motion, finds out that window also slightly widens to the observation mirror two ends.

Claims (2)

1. panel computer observation mirror of watching the small screen 3D left and right sides format image, comprise two groups of plane mirrors that eyepiece catoptron and object lens catoptron constitute, eyepiece catoptron central vision place apart from eyes less than 20mm, the angle that eyepiece catoptron and eye center sight line form is less than 45 degree, and symmetry is regulated the mechanism that finds out sight line, it is characterized in that the spacing at the eyepiece catoptron of this device and object lens catoptron central vision place less than 28mm, the central vision that two object lens catoptrons are found out goes out the spacing at shell place less than 125mm.

2. panel computer observation mirror according to claim 1 is characterized in that this observation mirror can add magnifier 100---200mm closely watches screen, and magnifier can be added between eyeball and the eyepiece catoptron, also can be added in observation mirror and find out the window place.
