If this moment, optical device 2 be half-wave plate, the half-wave plate translational vibration is to selection area 11 scopes, and selection area 11 self image forms linearly polarized light after selection area 11 outgoing and passes through half-wave plate with its polarization direction 90-degree rotation;
If this moment, optical device 2 be electro-optic crystal, electro-optic crystal applies voltage, and selection area 11 self image forms linearly polarized light after selection area 11 outgoing and passes through electro-optic crystal with its polarization direction 90-degree rotation; This moment, external electric field caused that electro-optic crystal produces electrooptical effect, makes the polarization direction 90-degree rotation of the linearly polarized light that is incident to electro-optic crystal because electro-optic crystal has applied voltage U;
(S05) from the non-display area 12 of optical device 2 outgoing should show and the linearly polarized light vertical incidence of the image that can not show to uniaxial crystal 3;
(S06) non-display area 12 should show and the linearly polarized light of the image that can not show through uniaxial crystal 3, deviations occurs, linearly polarized light after deviation is propagated along incident direction after outgoing from uniaxial crystal 3, non-display area 12 should be shown and the image generation translation that can not show is presented on position corresponding to the non-display area 12 adjacent with selection area 11.
Below in conjunction with specific embodiment, a kind of application process of eliminating the device of lcd screen piece in the present invention is further explained.
If selection area show the moment of one's respective area picture signal be t1 constantly, show that non-display area 12 should show and the moment of the picture signal that can not show be t2 constantly.
Embodiment 1
As Fig. 3, at t2 constantly, the selection area 11 at LCD panel 1 display area edge shows that non-display areas 12 should show and picture signal B2, the C2 picture signal that can not show, middle viewing area still shows the A picture signal, at this moment before half-wave plate is positioned at the selection area 11 of LCD panel 1, the fast axle of half-wave plate becomes 45 degree with the picture signal optical vibration direction of outgoing from LCD panel 1, picture signal light changes 90 degree through half-wave plate rear polarizer direction, then enters uniaxial crystal 3.Linearly polarized light direction of vibration after change of polarized direction is parallel to principal plane, is special ray concerning uniaxial crystal 3, so direction of propagation generation deviation, and image is presented on the position of non-display area 12 correspondences to the 1 edge translation of LCD panel.The picture signal light of middle viewing area is through transparency carrier 4, and in the middle of being presented at, on the correspondence position of viewing area, display effect as shown in Figure 4.Show complete after, according to the image switching frequency, before half-wave plate moves back to non-display area 12 before the selection area 11.
Because the image switching frequency is very fast, utilize the persistence of vision effect of human eye, will see the continuous demonstration image that there is no frame, effect is as shown in Figure 5.

When selection area (11) self image is presented at the selection area (11) of LCD panel (1) constantly at t1, with described half-wave plate translational vibration to non-display area (12) scope, the flashlight of selection area (11) self image form after selection area (11) outgoing linearly polarized light without the direct vertical incidence of half-wave plate to uniaxial crystal (3);
When constantly entering t2 constantly according to the image switching frequency from t1, non-display area (12) should show and the image that can not show when being presented at the selection area (11) of LCD panel (1), with the half-wave plate translational vibration to selection area (11) scope, non-display area (12) should show and the flashlight of the image that can not show form after selection area (11) outgoing linearly polarized light through after half-wave plate again vertical incidence to uniaxial crystal (3).
8. application process according to claim 6, it is characterized in that, described optical device (2) is front and cover the electro-optic crystal of selection area (11) fully for being arranged on the selection area (11) of LCD panel (1), when selection area (11) self image is presented at the selection area (11) of LCD panel (1) constantly at t1, electro-optic crystal does not apply voltage, and the flashlight of selection area (11) self image forms linearly polarized light after selection area (11) outgoing and keeps former polarization direction vertical incidence to uniaxial crystal (3) through electro-optic crystal;
When constantly entering t2 constantly according to the image switching frequency from t1, non-display area (12) should show and the image that can not show when being presented at the selection area (11) of LCD panel (1), electro-optic crystal applies voltage, non-display area (12) should show and the flashlight of the image that can not show forms linearly polarized light through electro-optic crystal rear polarizer direction rotation 90 degree after selection area (11) outgoing, then vertical incidence is to uniaxial crystal (3).
9. the described application process of according to claim 7 to 8 any one, it is characterized in that, the width of described uniaxial crystal (3) equals the summation of selection area (11) and non-display area (12) width, and its length equals the length of selection area (11) or non-display area (12).
