Embodiment Construction

[0011] exist figure 1 In the shown first embodiment, the first transparent substrate 7 is made of glass or transparent resin material, and the middle partition 9 is made on the first transparent substrate 7, and the middle partition 9 is made of conductive material, such as metal material indium steel, Or conductive polymer material, or silver electrode material etc., also can be made of the dielectric material that surface is coated with conductive layer, for example cover conductive polymer material etc. on the plexiglass, cover on the first transparent substrate 7 that is made with intermediate partition 9 Hydrophobic layer 5, hydrophobic layer 5 can adopt materials with stronger hydrophobicity such as Teflon, in order to prevent hydrophobic layer 5 from being broken down by applied voltage, can make a layer of insulating medium layer under hydrophobic layer 5 first, for example adopt polyimide The dielectric layer is simplified and not shown in the figure. The middle parti...

Abstract

The invention provides a slim liquid lens array which relates to a kind of slim type device with wide visual angle, which can freely convert two-dimension image and three-dimension stereo image display. The first transparent substrate (7) is produced on the middle compartmentation (9), the first transparent substrate (7) and the middle compartmentation (9) are covered with drainage blanket (5), the mesh of the middle compartmentation (9) is filled with the first liquid (10), the height of the first liquid (10) is equal to the middle compartmentation, the first conductive electrode (2) is produced below the second transparent substrate (1), the second liquid (8) is contacted with the first liquid, and is sealed between the middle compartmentation (9) and the second transparent substrate.

Description

technical field [0001] The invention relates to a liquid lens array, in particular to a wide viewing angle, thin and variable focal length liquid lens array. Background technique [0002] Image integrated stereoscopic display technology (integral imaging) is a true three-dimensional stereoscopic display technology, which can realize continuous motion parallax. Traditional image-integrated stereoscopic displays use a lens array with a fixed focal length. The applicant disclosed a variable-focus lens three-dimensional display in the Chinese patent application CN200710022982.4. This invention provides a liquid lens array with variable focal length, which has the characteristics of free conversion between two-dimensional display mode and three-dimensional display mode. However, in this invention, the middle partition located between the front and rear transparent substrates will affect the viewing angle range of the three-dimensional stereoscopic image. The thicker the partitio...
