Abstract

The present invention relates to a dual electrowetting liquid lens array panel which does not have a blind spot between side walls. In case of an existing a liquid lens array formed on a single board, a blind spot is formed by sidewalls for forming an adjacent liquid lens. The structure of the liquid lens array panel removes an invalid space formed by the sidewalls composed of dual boards having liquid lens array patterns arranged in two-dimensional.

Description

DUAL LIQUID LENS ARRAY PANEL OF ELECTROWETTING WITHOUT BLIND SPOT OF SIDEWALL}

The present invention relates to a liquid lens panel composed of a double substrate including liquid lens cells alternately formed to alternately form a gap formed by the cell partition walls constituting the lens in a liquid lens panel using a single substrate. A dual electrowetting liquid lens array panel which minimizes the gap created by the partition walls of adjacent liquid lens cells by forming a liquid lens array panel comprising an array of liquid lens cells formed of oil and water alternately across one another in a plane. It is about.

Liquid lens is a focal variable lens made by using electrowetting phenomenon to change the shape of droplets by changing the spreadability of droplets electrically by using electrodes coated with insulating film. Refers to a device that forms a lens according to a change in the angle between the water and the oil.

In the case of a panel consisting of a conventional electrowetting liquid lens cell, a partition wall for containing oil and water constituting each liquid lens is required, and a space is formed as much as a partition wall of the adjacent liquid lens cell. It passed through as it was and was an invalid space between the liquid lens cell and the cell.

Accordingly, there is a need for a design and structure of a liquid lens array panel that minimizes the size of the invalid area created by the partitions of adjacent liquid lens cells.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to alternately two-dimensionally with each other to remove the space of the partition wall for forming each liquid lens constituting the conventional liquid lens array. The present invention provides an array structure of a liquid lens panel formed by combining two liquid lens array panels in which a formed liquid lens cell is formed.

In order to achieve the object of the present invention,

The liquid lens substrate 106 is configured to include another substrate 206 formed with the liquid lens alternately formed in two dimensions opposite to each other to achieve the object of the present invention.

According to the present invention including the above-described configuration, the following effects can be obtained.

The dual electrowetting liquid lens panel without cell-cell partition pattern uses a liquid lens array panel having a liquid lens pattern formed two-dimensionally alternately with each other and another liquid lens array panel having a liquid lens formed in a pattern opposite to the above pattern. This eliminates blind spots created by the partition walls forming the respective liquid lens cells, thereby enabling a liquid lens array panel in which all incident light passes through the lens to form an image.
