Embodiment Construction
[0037] Combine below Figure 1 to Figure 8 This embodiment will be described.
[0038] see figure 1 , figure 1 The schematic diagram of the coplanar electrode blue phase liquid crystal lens ( figure 1 Only one lens unit is drawn). The coplanar electrode blue phase liquid crystal lens includes an upper substrate 101, a lower substrate 102, m groups of coplanar electrodes, an insulating barrier strip 105 and a blue phase liquid crystal layer 106; the insulating barrier strip 105 has the effect of electric field insulation barrier; the blue phase The liquid crystal is located between the strip electrode 104 and the common electrode 103 in the same coplanar electrode combination unit, and is driven to deform by the electric field formed between the strip electrode 104 and the common electrode 103 .
[0039] The working mechanism of the blue-phase liquid crystal is based on the Kerr effect. It is isotropic when no power is applied. The molecules of the blue-phase liquid crystal...

The invention relates to a coplanar-electrode blue phase liquid crystal lens and preparation methods thereof, relating to the technical field of 3D display with the view of solving problems of a nematic phase liquid crystal lens such as blur dynamic image induced by low response speed, high requirements for voltage and response time induced by thickness changes of a liquid crystal box as well as 3D image crosstalk.The coplanar-electrode blue phase liquid crystal lens comprises an upper substrate, a lower substrate, m groups of coplanar-electrodes, insulation barrier strips and blue phase liquid crystal layers. The upper substrate and lower substrate run in parallel. The m groups of coplanar-electrodes are arranged between the upper substrate and lower substrate from the left to the right at equal intervals. An insulation barrier strip is arranged between every two adjacent groups of coplanar-electrodes. The coplanar-electrodes are composed of stripped electrodes and public electrodes in parallel. The stripped electrodes and the public electrodes are vertical to the upper substrate. The blue phase liquid crystal layers are filed between the stripped electrodes and the public electrodes. Two preparation methods are designed to prepare the coplanar-electrode blue phase liquid crystal lens.
Description
technical field [0001] The invention belongs to the technical field of 3D display. Background technique [0002] The early stereoscopic display technology mainly used additional devices such as glasses and stereoscopic helmets to watch stereoscopic images, while the current mainstream naked-eye 3D display mainly uses a light-splitting device such as a slit grating or a cylindrical lens grating bound in front of the flat-panel display. The main function of the device is to perform spatial light modulation on the passing light, that is, to modulate the light of different viewpoint images differently according to the design requirements, so that it can reach the corresponding viewing area, and obtain stereoscopic perception after brain fusion. The slit grating uses the principle of light occlusion to split light, so that the odd and even sub-pixels display left and right parallax images respectively; the cylindrical lens grating uses the principle of light refraction to split l...
