Electric wetting lens and forming method thereof

Abstract

The invention discloses an electric wetting lens and a forming method thereof. The forming method comprises the following steps of: providing a first substrate and forming a first transparent electrode on the first substrate; providing a second substrate and forming a second transparent electrode on the second substrate; forming a dielectric layer on the second transparent electrode; oppositely assembling the first substrate and the second substrate; clamping a polar liquid with photopolymerisable matters and a non-polar liquid with photopolymerisable matters between the first substrate and the second substrate; and irradiating the first substrate and the second substrate which are assembled to solidify the photopolymerisable matters in the polar liquid and the non-polar liquid so as to form a retaining wall structure between the first substrate and the second substrate. The electric wetting lens has the advantages of simplicity in preparation process and high product yield.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for forming an electrowetting lens and the electrowetting lens. Background technique [0002] Electrowetting (Electrowetting) is a microfluidic phenomenon. Using electrowetting or electrocapillary (Electrocapillary) phenomenon, when a polar fluid is subjected to an electric field, the surface shape of the fluid is changed, making the surface distribution of the polar fluid changes happened. Electrowetting technology has begun to be widely used as a driving mechanism for various fluidic and electro-optic devices. The liquid lens using the electrowetting phenomenon, like the human eye, can automatically adapt to the object it is aiming at without the assistance of a mechanical device. It only needs to change the voltage of the two poles to modify the shape of the liquid to achieve the purpose of focusing and zooming. . Compared with traditional lenses, electrowetting l...

Problems solved by technology

In the existing process of forming the retaining wall structure 28 first and then assembling the first substrate 30 and the second substrate 22, instilling the polar liquid 40 and the non-polar liquid 45 requires parameters such as instillation position and instillation volume in the process. Moreover, in the process of forming the retaining wall structure 28, the position deviation of the retaining wall structure 28 or the defect of damaging the retaining wall structure 28 caused by the problem of assembly and alignment are prone to occur.
