Broad spectrum displayer covering visible light to infrared wave band

Abstract

The invention discloses a broad spectrum displayer covering visible light to an infrared band. The broadband spectrum displayer covering the visible light to the infrared band consists of an array of display units; the display unit comprises a second electrode (9), a hydrophobic insulating layer (8), a fluid chamber (2), a blocking layer (6), a medium layer (5), a first electrode (4), a substrate (3) and an illumination layer (14) which are successively arranged from the top to the bottom; and the two ends of a periphery driving circuit (13) are respectively connected to the first electrode (4) and the second electrode (9). The broad spectrum displayer covering the visible light to the infrared band uses a localized surface Plasmon resonance effect of Plasmon nanometer particles. When distance between nanometer particles changes, a spectral peak of a spectrum can move so as to change the color of a display unit and realize the dynamic tuning of the spectrum. The broadband spectrum displayer can fast respond, can be used as a micro-displayer to be applied to an anti-fake label and can realize flexible display, and is low in cost and simple in manufacture technology.

Description

technical field [0001] The invention belongs to the fields of display technology and metal nanomaterials, and relates to a wide-spectrum display covering visible light to infrared bands. Background technique [0002] At present, the electrowetting display is a new type of display based on the principle of electrowetting. Different from the existing LCD, it uses the electrowetting phenomenon and does not need to be equipped with polarizers to filter stray light. It has fast response speed and high light utilization efficiency. With the advantages of high height, wide viewing angle range and extremely low energy consumption, it can meet various display requirements and has a good application prospect. It has been widely used in mobile phones, cameras, watches, DVD players, computer monitors, GPS and other fields. In recent years, with the development of optical technology and electronic technology, people have higher and higher requirements for new display devices, especially ...
