Accompanying drawing explanation
Fig. 1 is the structural representation of the 3D liquid crystal indicator that the embodiment of the present invention provides.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
For 3D liquid crystal indicator, realization of the present invention is described in detail below.
As shown in Figure 1, the polaroid 4 that the 3D liquid crystal indicator that the embodiment of the present invention provides comprises liquid crystal panel 1, multiple pointolite 2 and is arranged between liquid crystal panel 1 and pointolite 2.Described liquid crystal panel 1 comprises multiple sub-pixel (sign), above-mentioned pointolite 2 and sub-pixel one_to_one corresponding.Described 3D liquid crystal indicator comprises panel drive circuit (not shown) and light source driving circuit (not shown) further, and described light source driving circuit is used for the luminosity controlling every bit light source 2 according to the light intensity value of sub-pixel each in picture signal in real time.Described panel drive circuit is used for the windup-degree controlling the liquid crystal molecule of each sub-pixel according to the left eye of sub-pixel each in picture signal or the light intensity value of right eye picture in real time, make the light changing two kinds of polarity from the unipolarity light of above-mentioned polaroid outgoing after liquid crystal panel into, enter left eye and right eye respectively.The control of the windup-degree of the liquid crystal molecule of above-mentioned each sub-pixel can be realized by the data voltage controlling this sub-pixel.Change the intensity from each sub-pixel emergent light in real time by described light source driving circuit, thus realize dynamic 3D picture.
This 3D liquid crystal indicator comprises a polaroid glasses (not shown) worn for human eye further.Usually, light is transferred to the process of human eye from above-mentioned pointolite 2, need through elements such as polaroid, liquid crystal, polaroid glasses, and all there is certain light transmission rate in these elements, the luminosity of the pointolite of each sub-pixel light loss can be produced, so should equal the light loss in the light intensity value sum superposition light transmitting procedure of the images of left and right eyes picture of each sub-pixel of picture signal.Suppose, light is transferred to the process of human eye from above-mentioned pointolite 2, have passed through above-mentioned polaroid, liquid crystal, colored filter and above-mentioned polaroid glasses, then the light intensity value sum that the luminosity of the pointolite of each sub-pixel should equal the images of left and right eyes picture of each sub-pixel of picture signal superposes the light loss of the light loss of above-mentioned polaroid, the light loss of liquid crystal, the light loss of colored filter and polaroid glasses.
Above-mentioned sub-pixel is a repetitive with three (such as red, green, blues) or more than three (such as red, green, blue, white).Utilize sub-pixel to take red, green, blue as repetitive below, pointolite is corresponding red-light LED, green light LED, blue-ray LED be illustrated.Wherein, ruddiness sub-pixel, green glow sub-pixel and blue photons pixel respectively with red-light LED, green light LED and blue-ray LED one_to_one corresponding.Certainly, pointolite also can adopt respectively with ruddiness sub-pixel, green glow sub-pixel and blue photons pixel white light LEDs one to one, now each sub-pixel color by one colored filter filter after produce.
Such as, in picture signal, the left eye picture light intensity value of certain three sub-pixel is R50, G200, B30, and right eye picture light intensity value is R40, G150, B70.Suppose that the light transmission rate of polaroid glasses is 30%, then the light that the red-light LED corresponding to above-mentioned three sub-pixels, green light LED, blue-ray LED send should be R(50+40 by the light intensity value after liquid crystal)/0.3=300, G(200+150)/0.3=1166.7, B(30+70)/0.3=333.3.Suppose that the light transmission rate of other optical elements such as liquid crystal is 90%, then the light that the red-light LED corresponding to above-mentioned three sub-pixels, green light LED, blue-ray LED send should be R300/0.9=333.3, G1166.7/0.9=1296.3, B333.3/0.9=370.3 by the light intensity value after above-mentioned polaroid 4.Suppose that the light transmission rate of above-mentioned polaroid is 30%, the luminous intensity of the red-light LED then corresponding to above-mentioned three sub-pixels, green light LED, blue-ray LED should be R333.3/0.3=1111, G1296.3/0.3=4321, B370.3/0.3=1234.3, and the light intensity value (i.e. luminosity) that in each sub-pixel, red-light LED, green light LED, blue-ray LED send is controlled by described light source driving circuit.Wherein, the light that described red-light LED, green light LED, blue-ray LED send light transmission rate after other optical elements such as polaroid 4, liquid crystal and polaroid glasses is R(50+40)/1111=8.1%, G(200+150)/4321=8.1%, B(30+70)/1234.3=8.1%, namely the light transmission rate of this 3D LCD TV is 8.1%, is that the light transmission rate rate twice of existing 3D LCD TV 3.97% is had a surplus.
The light that red-light LED, green light LED, blue-ray LED send is by being converted to unipolarity light after described polaroid 4, suppose that the light after by described polaroid 4 is P light, and this P light is received by left eye, then need part P light to be converted into the S light that right eye receives, in this sub-pixel, the conversion ratio of three coloured light is respectively R40/(50+40)=44.4%, G150/(200+150)=42.8%, B70/100=70%.Can the windup-degree of liquid crystal molecule be controlled by the data voltage controlling each sub-pixel and realize herein.
Wherein, two polarity of P light and S light representations light, two eyeglasses of polaroid glasses there is opposite polarity light polarizing film, as left eyeglass lens can allow P light pass through, right eye eyeglass can allow S light pass through, such left eye sees that the light intensity value of this pixel is R50, G200, B30, and right eye sees that the light intensity value of this pixel is R40, G150, B70, thus makes people experience 3D effect.
Compared to prior art, 3D liquid crystal indicator of the present invention adopts pointolite and sub-pixel mode one to one, by while the luminous intensity of reference mark light source and the windup-degree of the liquid crystal molecule of sub-pixel, realize the outgoing of two kinds of polarity light.The present invention only needs one to be located at polaroid between liquid crystal panel and pointolite, eliminate two polaroids above traditional 3D liquid crystal indicator, improve light transmission rate greatly, and, 3D liquid crystal indicator of the present invention does not need interlacing to carry out polarisation, each sub-pixel has the light outgoing of two kinds of polarity, so resolution can not reduce.
The present invention also provides a kind of 3D LCD TV with above-mentioned 3D liquid crystal indicator.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, such as above-mentioned 3D liquid crystal indicator or 3D LCD TV also can not comprise above-mentioned polaroid, but directly utilize the pointolite can launching unipolarity light to replace above-mentioned polaroid and above-mentioned pointolite, so more save the use of polaroid.
