Abstract
The present invention provides a polaroid sheet device. The structure of the polaroid sheet device based on the present invention matches with a polarized light with an electric field direction. In particular, the polaroid sheet device based on the present invention can ensure a polaroid sheet to be adjusted to a proper observing angle automatically.
Description
Technical field
The present invention is about a kind of polarizer device (Polarizer device), and its structure is the polarized light that cooperation one has a direction of an electric field.And more particularly, the present invention is about a kind of polarizer device that makes polaroid automatically be adjusted to appropriate viewing angle.
Background technology
Can be before the image of 3D screen is exported earlier by a slice polarization plates, the image that this polarization plates is gone into tendency to develop eyes in advance is divided into the polarized lightwave of two mutually orthogonals, that is if a polarization direction horizontal direction of image, then another polarization direction is vertical direction.Relatively, the polarising glass that the user wore also is to be divided into the image that left and right sides picture frame receives the different polarization direction separately.If the left picture frame of polarising glass is horizontal mating plate, then only allows the horizontal polarization image pass through, and the vertical polarization image is kept off.Similarly, if the right picture frame of polarising glass is the vertical polarization sheet, then only allows the vertical polarization image pass through, and cover the horizontal polarization image, human eye is exactly to see different images by left eye and right eye, and then produces parallax effect and form the 3D picture in brain.In theory, the start situation of polaroid as mentioned above.In fact, in use then can be and cause the deviation of each polaroid angle with respect to the polarization image because of the action of people's posture or head, cause the light leak and the colour cast situation that cause in various degree.In other words, the polaroid of screen and glasses is collocation mutually.When the polarized light of screen output was vertical direction and horizontal direction, the polaroid angle of eyeglass is matching polarized light direction relatively just.
Yet, be used for watching the polarizer device of 3D image all can't automatically adjust the angle of polaroid now.That is to say,, cause to produce the phenomenon that right and left eyes information interferes with each other if when the employed polarizer device of user tilts an angle to the left or to the right, then can't correctly receive horizontal or vertical image.
Therefore, a category of the present invention provides a kind of polarizer device, can make polaroid automatically be adjusted to appropriate viewing angle under its structure.
Summary of the invention
According to a preferred specific embodiment, the structure of polarizer device of the present invention is the polarized light that cooperation one has a direction of an electric field.Polarizer device comprises first framework, second framework and polaroid.First framework is assembled to be connected object or to be worn on the people on the face.Second framework is connected first framework rotationally, and second framework definition horizontal center line itself and vertical center line.Polaroid is fixed on second framework, and polaroid has a smooth direction of passage, wherein second framework has a center of gravity, the position of center of gravity is positioned at vertical center line and off-set from horizontal centerline, and the relative position of this position and horizontal center line and vertical center line is for fixing, make the horizontal center line and the surface level keeping parallelism of second framework, when even first framework tilts, the horizontal center line of second framework and surface level still can be by the effects of this center of gravity and keeping parallelism, that is, but the light direction of passage of the polaroid direction of an electric field of parallel polarized light still.
Can be further understood by following embodiment and accompanying drawing about the advantages and spirit of the present invention.

Embodiment
The invention provides a kind of polarizer device, and especially, under its structure, can make polaroid automatically be adjusted to appropriate viewing angle.Preferred specific embodiment of the present invention below will be described in detail in detail, so as to the simplicity in abundant explanation feature of the present invention, spirit, advantage and the enforcement.
See also Fig. 1, Fig. 1 is the synoptic diagram of expression polarizer device 1 and the polarized light 2 that cooperates its structure.As shown in Figure 1, the structure of polarizer device 1 is to cooperate the polarized light 2 with direction of an electric field 22.See also Fig. 2, Fig. 2 is the synoptic diagram of expression according to the foundation structure of the polarizer device 1 of of the present invention one preferred specific embodiment.As shown in Figure 2, polarizer device 1 comprises first framework 12, second framework 14 and polaroid 16.First framework 12 is assembled to be connected an object (for example, measuring the camera lens of the instrument of 3D display device) or to be worn on people (that is watch 3D image in order to be performed to wear) on the face.Second framework 14 is connected first framework 12 rotationally, and second framework 14 itself defines horizontal center line 142 and vertical center line 144.Polaroid 16 is fixed on second framework 14, and polaroid 16 has light direction of passage 162.
See also Fig. 3, Fig. 3 is the heeling condition synoptic diagram of expression according to the polarizer device 1 of of the present invention one preferred specific embodiment.As shown in Figure 3, wherein second framework 14 has center of gravity G, the position of center of gravity G is positioned on the vertical center line 144 and off-set from horizontal centerline 142, and the relative position of this position and horizontal center line 142 and vertical center line 144 is for fixing, make the horizontal center line 142 and surface level 3 keeping parallelisms of second framework 14, when even first framework 12 tilts, the horizontal center line 142 of second framework 14 and surface level 3 still can be by the effects of this center of gravity G and keeping parallelism, that is, but the light direction of passage 162 of polaroid 16 direction of an electric field 22 of parallel polarized light 2 still.
As shown in Figure 2, in order to make the smooth-going ground of second framework 14 and to be connected rotationally that 12, the second frameworks 14 can connect with first framework rank 12 rotationally by bearing 13 (Bearing) on first framework.In this embodiment, bearing 13 is a ball bearing.
In addition, in another preferred specific embodiment, bearing 13 also can be rolling bearing, fluid bearing or other similar assembly.
