200928445 IX. Description of the Invention: [Technical Field] The present invention relates to a special liquid crystal lens design which has the function of switching between electrodes and applying voltage to change the refractive index of liquid crystal. In order to switch the focusing characteristics of the lens, one or more beam deflection behaviors are generated. In particular, it refers to a component that can be applied to a camera optical lens with autofocus (aut〇f〇cus) to change the focal length of the lens to produce a variety of different focus positions. Therefore, the technical fields to which it belongs are mainly related technologies such as liquid crystal optical elements, optical lenses, and camera lenses.

[Prior Art] Conventional cameras using photoreceptors have gradually been replaced by digital cameras with built-in image sensing elements, and are oriented toward sorghum, autofocus.

In addition to replacing traditional cameras, digital camera applications have expanded into other areas of innovation, one of which is the use of mobile phones. Since the launch of the first additional camera-enabled mobile phone in Japan in 2000, the camera mobile phone has become the hottest product in the mobile communications industry, and has recently developed into one of the world's best-selling products.

Before the development of the camera, lying on the camera phone lens group, the practice is roughly = voice coil m〇t〇r , VCM), ink electricity (piez〇dectric) actuation = with micro stepping motor. There is also a liquid ens system that can change the curvature of the lens by electromoping to change the curvature of the lens to achieve a change in focusing characteristics. The use of these methods to achieve the purpose of autonomy has its own lack of actuators that use mechanical dynamics. The material cost and the antikhoek characteristics are all _; while using a static liquid lens, Two-way technology and optical imaging quality are also challenges. Therefore, it is a better technique to study the autofocus of the two modules of the handcuffs and ❹ 2 modules.斟Describe, simple, stable, anti-fall, easy to produce auto focus 4 set to develop an important goal of mobile phone camera module. To achieve this goal, non-mechanical, by applying voltage control to change the optical properties of the lens - the feasible direction. Over the years, there have been many literature materials (liqUidCiyStal, LC) optical component technology, to explore the use of liquid crystal applied voltage to modulate the special optical characteristics of the refractive index, to change the focal length of the transparent, and used in various product fields. The earliest concept of using liquid crystals and refractive optical elements was revealed in USP 4〇66334 US Patent 2, 'Please refer to the "i-th picture", which uses the modulation of the applied voltage to change the refractive index of the liquid crystal. The beam of the human beam is biased in the liquid crystal (4). The characteristics of the liquid crystal can be used for the creation of liquid crystal components. For example, please refer to "2nd picture", which is disclosed in (4) into the US patent publication, and the crane liquid crystal The electrode is designed to be a zoneplate diffraction pattern, which is a diffractive liquid crystal with 4 objective lenses to produce two different positions of focused light, applied to multiple layers of optical pickup heads.

Its optical stern. For example, in the application of J = (Vol. 43, No. 35, ρ. 6407, December, 2004), the electrode is designed on the other side of the glass thicker than the liquid crystal dielectric layer. The effect of high voltage, = potential distribution after penetrating through the glass, the formation of a continuous curved surface distribution in the liquid crystal dielectric layer ^ and thus the continuous distribution of the refractive index of the liquid crystal, like a continuous phase distribution, the characteristics of the remarks / defocus, the component structure It is also simple; however, its driving voltage should be as much as 100 volts. It is much driven by less than about 5 volts of the general liquid crystal element. Same as <previously = conventional liquid crystal optical components such as USP6577376 and USP6690500 using strip or Fresnel Lens The design of the element is limited by the diffraction order, which reduces the overall utilization efficiency of the beam. The usp6864951 adopts the structure of the polymer-dispersed liquid crystal and the exposure process of the ultraviolet light is strict, and the transmittance of the medium due to scattering Low voltage and high component driving voltage have many limitations. The most important factor is the birefringence characteristic of liquid crystal, so its optical variability 有 has an effect on a specific polarized incident beam, thus limiting ^ The scope of application. The above-mentioned prior art can only be used in optical systems such as lasers, which include polarizers and analyzers, and is not used in 200928445. The imaging system of the light source is thus disclosed in the liquid crystal lens design of the U.S. Patent No. 9333, which adopts a two-layer liquid helium structure to solve the problem of polarization of the liquid crystal element to polarization (the problem of polarization, but this creation) The spherical electrode substrate is used, and the liquid crystal layer of the hook is used to drive the liquid crystal to compensate the curvature of the spherical electrode to be variable. The purpose of the focal length; the production of the spherical electrode is also the main difficulty for this creation.

Only the liquid crystal lens formed by the concentric annular electrode group has a phase modulation effect, so that two identical liquid crystals can be combined. By making the alignment of the two liquid crystal layers perpendicular to each other, the two liquid and two layers respectively have a phase modulation effect corresponding to the two polarized lights which are perpendicular to each other, and the two liquid crystal lenses are stacked. Combined, it can have a complete phase and modulation effect on the generally non-polarized incident light, and The imaging system can be applied to a general non-polarized light source. In particular, the camera module can be matched with a conventional fixed focal length, and the incident beam can be corrected according to the distance of the object, so that the defocused spot concentrated on the imaging surface is compensated, and the image is reduced. 11 200928445 妙妙实1 Non-automatic autofocus effect.

A total of three #transparent substrates (10) are separated by spacers 15G, and a liquid crystal medium (10) is filled therebetween, and the thickness of the liquid crystal layer is determined by the diameter of the gaps 150. The implementation is performed on the first and lower surfaces of the plate 112, the second and the first electrode groups and the first annular electrode group, and the two common electrodes a are divided into the first transparent substrate 111.

The two sets of annular electrode sets m are made in different designs to achieve optimal focus hiding. In addition, in order to consider the influence of the area occupied by the electrode wires 123 on the annular electrode group 122, the electrode wires 123 of the first ring-shaped electrode group 122a and the second ring-shaped electrode group 122b are staggered as far as possible in different regions.
