New description: ., [New technical field] This creation is about one type and has LCD reading in / T .. , and the show is only available in the Liquid Crystal Lens. It is about a two-layer (10) plane image and three-dimensional (3D) with a two-layer liquid crystal lens: a stereoscopic display device and a different electrode pattern in a double-layer liquid crystal lens. Stereoscopic image. [Prior Art] ^ With the advancement of liquid crystal displays, the display technology of three-dimensional (3D) stereoscopic images has developed rapidly and has gradually penetrated into consumer lifestyle towels. In general, three-dimensional (3d) stereoscopic image display technology is implemented through the eyes of the user and in accordance with the principles of stereoscopic vision. Conventionally, a 3D stereoscopic image display device is designed based on the basis of binocular parallax, so that the user's left eye only views the image to the left eye and the right eye only views the image to the right eye. Since human eyes are about 5 to 7 cm apart from each other, binocular parallax is called, that is, the images seen by the two eyes are different images with slight differences due to the difference in position between the left and right eyes. The difference between the images viewed by the left and right eyes caused by such eye position difference is called binocular parallax. The use of binocular parallax to create a three-dimensional display is often achieved by wearing special tools. Common methods include using polarized glasses, red and blue (green) glasses, shutter glasses, and a head-mounted display. However, the display method described above requires the user to wear a special device to view a stereoscopic image regardless of the cost, and thus it is inconvenient for the user. 4 M398632 In order to increase the diversification of applications and obtain more natural π vertical images, in recent years, it has been focused on development without the need to wear any special devices;; naked-eye 3D stereoscopic display devices to stereoscopic images, eye-type buckles are not visible The optical technology used in the device mainly includes "columnar lens parallax barrier or slit parallax (Par. x Barrier)". "column (four) mirror" technology
理主W運用凸透鏡折射原理，同時分割將影像 又向左右眼’以達立體效果。而「視差屏障』運用光的 直線傳播的性質，將多視角影像透過一整排細微的狹縫所 組成的視差屏障’再入射至雙眼以產生立體視覺。 由於3D立體影像應用逐漸普遍，因此市面上之顯示 ，置，逐漸開發可切換3D立體影像顯示與扣影像顯;之 裝置’以滿足同一顯示裝置具有兩種顯示類型之需求。然 而上立述之各種裸眼式3D立體顯示裝置，不論是使用「柱 狀透二」产4見差屏障」之技術原理，皆需於顯示器中設 =式的光予元件，例如柱狀透鏡或黑色間隙屏障，而 增加沒些額外的3D光學元件，亦造成無法顯示2d影像的 結果。 爲了能有效顯示3D影像且可顯示2D影像品質，某些 ^ .切換裝置開始應用液晶透鏡，藉由轉換光學元件來 造成光傳播相位改變’達到2D與3D影像間高自由度的切 、匕種方式稱為「液晶透鏡（Liquid Crystal lens，ELC lens)」’其技術原理係藉由液晶受電場驅動後，造成液晶 有同自t焦透鏡（Grin Lens)的折射率變化。 叫參考第1A、1B圖所示之「電場驅動液晶透鏡」技 5 M398632 術原理之示意圖。如第1A圖所示，當未施加電壓於液晶 胞（LC cell)時，液晶長軸依照配向膜（Alignment layer)配向 傾倒’此時光波之傳播方向（propagation direction)將不受 影響；如第1B圖所示’當施加電壓於液晶胞時，上下電 極層因電位勢不同’而形成由上向下之電場分佈，而透鏡 邊緣之電場強度小於透鏡中心之電場強度，此種電場分佈 不一致造成液晶傾斜角度不同的情況，此時光波之傳播方 向將隨液晶折射率的變化而改變。因此，當利用「電場驅 動液晶透鏡」應用於2D/3D切換顯示之裝置時，當不施加 電壓於液晶胞時，面板所發之光波的傳播方向不受液晶胞 影響’故^ 2D顯示；當施加電壓於液晶胞時，面板所發 之光波的傳播方向受到液晶胞之影響，因此可達到3d顯 示之目的。 然而’此種方式仍面臨許多製程上需要克服的問題。 由於液晶透鏡之焦距斑液a馬认府—The master W uses the principle of convex lens refraction, and at the same time divides the image to the left and right eyes to achieve a three-dimensional effect. The "parallax barrier" uses the nature of the linear propagation of light, and the multi-view image is transmitted through a whole row of fine slits to the parallax barrier to re-enter the eyes to produce stereoscopic vision. Since 3D stereoscopic image applications are becoming more common, On the market, the display has gradually developed a switchable 3D stereoscopic image display and button image display; the device 'satisfy the need for the same display device to have two display types. However, the various naked-eye 3D stereoscopic display devices described above, regardless of It is the technical principle of using the "column 2" barrier, which requires a light-emitting component such as a lenticular lens or a black gap barrier in the display, and adds no additional 3D optical components. It also results in the inability to display 2d images. In order to effectively display 3D images and display 2D image quality, some switching devices start to apply liquid crystal lenses, and the optical propagation phase is changed by converting optical elements to achieve high degrees of freedom between 2D and 3D images. The method is called "Liquid Crystal Lens (ELC lens)". The technical principle is that after the liquid crystal is driven by the electric field, the liquid crystal has the same refractive index change from the t-focus lens (Grin Lens). Refer to the schematic diagram of the principle of "Electrical Field Driven Liquid Crystal Lens" 5 M398632 shown in Figures 1A and 1B. As shown in FIG. 1A, when no voltage is applied to the LC cell, the long axis of the liquid crystal is tilted according to the alignment of the alignment layer. At this time, the propagation direction of the light wave will not be affected; 1B shows that when the voltage is applied to the liquid crystal cell, the upper and lower electrode layers are different in potential potential to form an electric field distribution from top to bottom, and the electric field intensity at the edge of the lens is smaller than the electric field strength at the center of the lens. When the tilt angle of the liquid crystal is different, the direction of propagation of the light wave will change with the change of the refractive index of the liquid crystal. Therefore, when the "electric field-driven liquid crystal lens" is applied to a device for 2D/3D switching display, when no voltage is applied to the liquid crystal cell, the direction of propagation of the light wave emitted by the panel is not affected by the liquid crystal cell, so 2D is displayed; When a voltage is applied to the liquid crystal cell, the direction of propagation of the light wave emitted by the panel is affected by the liquid crystal cell, so that the display can be achieved for 3d. However, this approach still faces many problems that need to be overcome in the process. Because the focal length of the liquid crystal lens is a spotted liquid

One of the advantages of this creation is that the user can use the 2D plane image or the 3D stereoscopic image according to the desired image when the image is captured or shot by the naked eye stereoscopic display device with the double liquid crystal lens. The image can be easily switched by applying a bias to the double-layer liquid crystal lens. 8 Another advantage of the present invention is that the image quality of the conventional stereo display device can be improved due to the lens principle. The focal length of the liquid crystal lens is limited by the thickness of the liquid crystal lens, and the process of the white knowing process cannot achieve the desired focal length.
