Abstract

The invention discloses an electrowetting device and a display device, comprising: a first substrate and a second substrate facing each other, and a support structure arranged between the first substrate and the second substrate; wherein, the support structure and the second substrate A substrate and a second substrate form at least one sealed cavity; a conductive medium, an insulating medium, a grating layer, a hydrophobic layer and an electrode pair are arranged in the sealed cavity; the hydrophobic layer is configured to control the conductive medium to cover the second substrate and pass the insulating medium and The first substrates are in droplet shape isolated from each other; the electrode pairs are configured to control the radius of the droplet-shaped conductive medium to be continuously adjustable; the grating layer and the conductive medium jointly control the light output angle of the electrowetting device. The radius of the droplet-shaped conductive medium is controlled by the electrode pair to be continuously adjustable, so that the light incident on the sealed cavity becomes a light with a dynamically adjustable exit angle after being diffracted by the grating layer and refracted by the conductive medium. The display device of the electrowetting device continuously changes the light emitting angle.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an electrowetting device and a display device. Background technique [0002] With the development of Internet technology and the abundance of material conditions, a wide variety of electronic devices such as mobile phones, computers, televisions, personal digital assistants, and digital cameras are more and more closely integrated with people's life and work. The demand for products is getting bigger and bigger, and the requirements are getting higher and higher. However, in the prior art, the viewing angle of the displayed product is usually fixed, and the flexibility is poor. Contents of the invention [0003] In view of this, an embodiment of the present invention provides an electrowetting device and a display device, which are used to realize the continuous change of the light output angle of the display device. [0004] Therefore, an electrowetting device provi...
