Description

technical field [0001] The invention belongs to the field of display devices, and in particular relates to a display panel and an electrowetting display device. Background technique [0002] The phenomenon of electrowetting (Electrowetting) is to use the inherent natural force of the interface between oil and water, using a highly hydrophobic material that can remove water from the surface and use the oil film as the medium to form a method of separating the oil phase and the water phase . Among them, the wetting effect of the water-resistant surface can change the interface properties by changing the voltage, making the original water-resistant surface more hydrophilic (or wet), hence the name electrowetting. Electrowetting Display (Electrowetting Display) is the use of electrowetting phenomenon or electrocapillary (Electrocapillary) phenomenon, when the liquid is subjected to an electric field to change the surface free energy (Free Surface Energy) of the liquid, so that ...

Problems solved by technology

[0004] In existing electrowetting display devices, non-polar dyeing liquid 6 is prepared by adding oil-soluble dyes or pigments of corresponding colors to non-polar liquids such as oil. The oil-soluble dyes or pigments themselves do not emit light, and The brightness is very dark, which makes the existing electrowetting display devices have a small color gamut, low brightness, and poor display picture quality

[0005] The Chinese patent with the application number 201220063851.7 discloses an "electrowetting display device", which uses the property of quantum dots to emit visible light when excited by external energy, and dissolves oil-soluble quantum dots in non-polar liquids such as toluene In the process, the brightness of the device can be increased to 50-80%, but the ability of oil-soluble quantum dots to dissolve in non-polar solvents is poor, so the advantages of stimulated light emission of quantum dots cannot be fully utilized; at the same time, when realizing the dark state mode , the device needs to set a UV blocking film under the non-polar liquid to absorb UV light, so as to prevent the quantum dots cohesively above it from being excited to produce visible light

The setting of the ultraviolet light blocking film makes the structure of the device complicated, increases the manufacturing process steps, and correspondingly increases the cost
