After the light source 10 emits the first bipolar light 101, only one of the two polarities of P1 and S1 of the first bipolar light 101 can enter due to the barrier of the first polarizer 205. For the first control panel 20, at this time, it is assumed that the light of the P1 polarity enters the first control panel 20 through the first polarizer 205; The position of the sub-pixel block controls the change of the voltage of the capacitance formed by the TFT facing up and down at this position, thereby changing the rotation amount of the liquid crystal molecules in each sub-pixel block, so that the light of the P1 polarity passes through all the sub-pixel blocks.

For further illustrating the course of work of the present invention, give an example as follows:

After the first bipolar light 101 emitted by the light source 10 passes through the first polarizer 205, only one of the two polarities of P1 and S1 can enter the first control panel 20, assuming the P1 polarity The light entering the first control panel 20 through the first polarizer 205, at this time, at the sub-pixel block position corresponding to each first control panel 20, control the capacitance formed by the TFT facing up and down at this position The voltage changes, thereby changing the amount of rotation of the liquid crystal molecules in each sub-pixel block, so that the light of the P1 polarity is converted after passing through the rotated liquid crystal molecules of the first liquid crystal layer 204 in each sub-pixel block. It is the third bipolar light (that is, two polarities of P2 and S2, not shown in the figure), and the light of the S2 polarity cannot pass through the second polarizer 206, so only the P2 polarity The polarized light, that is, the first unipolar light 201 enters the second control panel 30 through the second polarizer 206 . The first unipolar light 201 enters the second control panel 30, at this time, at the position of the sub-pixel block corresponding to each second control panel 20, the capacitance formed by the TFT facing up and down at this position is controlled. The voltage changes, thereby changing the amount of rotation of the liquid crystal molecules in each sub-pixel block, so that the first unipolar light 201 passes through the rotated liquid crystal molecules of the second liquid crystal layer 304 in each sub-pixel block, converted into the second bipolar light 301 (that is, two polarities of P3 and S3).

In this process, the driving circuit will determine the amount of rotation of the liquid crystal molecules of each sub-pixel block according to the brightness of the TV signal, thereby converting the intensity and polarity of the light. In the first control panel 20, the first The unipolar light 201, that is, the light of the P2 polarity, is a light whose intensity value needs to be controlled, and the intensity value of the first unipolar light 201 is equal to the first unipolar light 201 after passing through the second control panel 30. The two polarities of the bipolar light 301 , that is, the sum of the light intensity values of the P3 and S3 polarities (the liquid crystal loss is ignored in the calculation process of this embodiment). For example, the first unipolar light 201 of a certain sub-pixel block after passing through the first control panel 20 is P2 (R126, G210, B67), and after passing through the second control panel 30, it is transformed into P3 (R46, G150, B37) and S3 (R80, G60, B30). Since the 3D LCD TV is equipped with special polarized glasses 60, the left and right polarities of the polarized glasses 60 are different, so the light of the two polarities of P3 and S3 will enter the left and right sides of the person wearing the polarized glasses 60 respectively. Right eye, assuming that the left eye is P and the right eye is S, then the left eye sees light as P3 (R46, G150, B37), and the right eye sees light as S3 (R80, G60, B30), so as to achieve the human left, The right eye sees different pictures respectively, which produces a three-dimensional feeling.

Since the TV signal contains the RGB intensity value data of the left and right eye pictures in each sub-pixel block, for example, the RGB intensity values of the left and right eye pictures of a certain sub-pixel block are respectively: left eye R50, G200, B30, right Eyes R40, G150, B70. At this time, assuming that the polarized glasses 60 have a light loss of 70%, the intensity value of the first unipolar light 201 passing through the first control panel 20 needs to be satisfied: R(50+ 40)/0.7=R128.6, G(200+150)/0.7=G500, B(30+70)=B142.8, namely: P2 (R128.6, G500, B142.8). At this time, the first unipolar light 201 needs to be converted into the second bipolar light 301 whose polarities are respectively P3 and S3 through the second control panel 30, that is, the liquid crystal panel needs to set the intensity value of The light of R40/0.7=57, G150/0.7=214.3, B70/0.7=100 is converted into the light of S3 polarity, at this time, it can be concluded that the first unipolar light 201 is converted into the second bipolar light The conversion rate of 301 is R: 44.4%, G: 42.8%, and B: 70%. Since liquid crystal molecules are birefringent substances, by controlling the angle at which light enters liquid crystal molecules, the polarity of the two kinds of light after exiting liquid crystal molecules can be controlled. In other words, each incident angle corresponds to a light conversion rate, and through the drive circuit, the rotation amount of liquid crystal molecules can be controlled by controlling the voltage of the capacitor formed by the TFT corresponding to each sub-pixel block. After adjusting the amount of rotation of the liquid crystal molecules and making the light pass through the liquid crystal molecules with birefringence properties to complete the light conversion, the original first unipolar light 201, that is, P2 (R128.6, G500, B142.8), turns to It is the second bipolar light 301 , that is, P3 (R71.4, G285.7, B42.8) and S3 (R57, G214.3, B100). At this time, since the two lenses of the polarizing glasses 60 have polarized films with opposite polarities, for example, the left eye can let the light of the P3 polarity pass through, and the right eye can let the light of the S3 polarity pass through, so that the light entering the left side can be precisely controlled. Eye and right eye images, so as to achieve a 3D effect.

In the embodiment of the present invention, after the first control panel 20 and the second control panel 30 are used, the first bipolar light 101 is converted into the second bipolar light 301 that meets the requirements, and at the same time, the second bipolar light The two polarities of the polar light 301 form different pictures respectively and enter the left and right eyes of the person through the polarized glasses 60, thereby producing a three-dimensional feeling. The structure of the present invention is simple, and it will not reduce the 3D liquid crystal The resolution of the panel.
