For further specifying the course of work of the present invention, be exemplified below:
The first bipolarity light 101 that described light source 10 sends is by after described first polaroid 205, the light of its P1 and two kinds of polarity of S1 only has a kind ofly can enter described first control panel 20, described first polaroid 205 of light transmission of supposing P1 polarity enters described first control panel 20, at this moment, in sub-pixel piece position corresponding to described each first control panel 20, the voltage of controlling the electric capacity of the relative up and down TFT formation in this position changes, thereby change the rotation amount of liquid crystal molecule in each sub-pixel piece, make behind the postrotational liquid crystal molecule of described first liquid crystal layer 204 of light in seeing through each sub-pixel piece of described P1 polarity, being converted into the 3rd bipolarity light (is two kinds of polarity of P2 and S2, figure does not show), and, the light of described S2 polarity can not see through described second polaroid 206, therefore, the light that described P2 polarity is only arranged also is the described first unipolarity light 201, sees through described second polaroid 206 and enters in described second control panel 30.The described first unipolarity light 201 enters in described second control panel 30, at this moment, in sub-pixel piece position corresponding to described each second control panel 20, the voltage of controlling the electric capacity of the relative up and down TFT formation in this position changes, thereby change the rotation amount of liquid crystal molecule in each sub-pixel piece, make the described first unipolarity light 201 behind the postrotational liquid crystal molecule through described second liquid crystal layer 304 in each sub-pixel piece, being converted into the second bipolarity light 301(is P3 and two kinds of polarity of S3).
In this process, described driving circuit can determine the liquid crystal molecule rotation amount of each sub-pixel piece according to the brightness needs of TV signal, thereby transform the intensity and the polarity of light, in described first control panel 20, the described first unipolarity light 201, also be the light of described P2 polarity, control the light of its intensity level for needs, the intensity level of the described first unipolarity light 201 equals two kinds of polarity through the second bipolarity light 301 behind described second control panel 30, also is the light intensity value sum (ignoring the liquid crystal loss in the present embodiment computation process) of P3 and S3 polarity.For example to see through the first unipolarity light 201 behind first control panel 20 be P2(R126 to certain sub-pixel piece, G210, B67), and when being converted into P3(R46 through after second control panel 30, G150, B37) and S3(R80, G60, B30).Because the 3D LCD TV is allotted special polaroid glasses 60 are arranged, the left and right polarity difference of described polaroid glasses 60 is so the light of this P3 and two kinds of polarity of S3 will enter the people's who wears polaroid glasses 60 images of left and right eyes respectively, suppose that left eye is P, right eye is S, and then people's left eye sees that light is P3(R46, G150, B37), that right eye is seen is S3(R80, G60, B30), thereby the images of left and right eyes that reaches the people is seen different pictures respectively, produces three-dimensional sensation.
Owing to comprise the intensity level data of the RGB of the images of left and right eyes picture in each sub-pixel piece in the TV signal, such as, the RGB intensity level of certain sub-pixel piece images of left and right eyes picture is respectively: left eye R50, G200, B30, right eye R40, G150, B70, at this moment, suppose that polaroid glasses 60 have 70% light loss, the intensity level that then needs to satisfy the first unipolarity light 201 that sees through described first control panel 20 is: R (50+40)/0.7=R128.6, G (200+150)/0.7=G500, B (30+70)=B142.8, also promptly: P2(R128.6, G500, B142.8).At this moment, need the described first unipolarity light 201 be converted into the second bipolarity light 301 that polarity is respectively P3 and S3 by second control panel 30, also be, then liquid crystal panel need be R40/0.7=57 with intensity level wherein, G150/0.7=214.3, the light of B70/0.7=100 transfers the light of S3 polarity to, at this moment, can draw the conversion ratio that the described first unipolarity light 201 is converted into the second bipolarity light 301 is R:44.4%, G:42.8%, B:70% because liquid crystal molecule is a disdiaclast, injects the angle of liquid crystal molecule by control light, can control the polarity that penetrates two kinds of light behind the liquid crystal molecule, that is to say the conversion ratio of the corresponding a kind of light of every kind of incident angle, and by described driving circuit, the voltage of the electric capacity that can form by the TFT that controls each sub-pixel piece correspondence is controlled the rotation amount of liquid crystal molecule.After the rotation amount of adjusting liquid crystal molecule and the liquid crystal molecule that makes light transmission have birefringence are finished the conversion of light, the original first unipolarity light 201, also be P2(R128.6, G500, B142.8), transfer the second bipolarity light 301 to, also be P3(R71.4, G285.7, B42.8) and S3(R57, G214.3, B100).At this moment, owing on two eyeglasses of polaroid glasses 60 opposite polarity light polarizing film is arranged, can allow the light of P3 polarity pass through as left eye, right eye can allow the light of S3 polarity pass through, so just can precisely control the picture that enters left eye and right eye, thereby reach the effect of 3D solid.
After the embodiment of the invention is passed through described first control panel 20 and described second control panel 30, the first bipolarity light 101 is converted into the second bipolarity light 301 that satisfies the demands, simultaneously, the light of two kinds of polarity of the described second bipolarity light 301 forms different pictures respectively and enters into people's images of left and right eyes by polaroid glasses 60, thereby produce three-dimensional sensation, the present invention is simple in structure, and it can not reduce the resolution of described 3D liquid crystal panel.
The above only is the preferred embodiments of the present invention; be not so limit its claim; every equivalent structure or equivalent flow process conversion that utilizes instructions of the present invention and accompanying drawing content to be done; directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
