Abstract

The invention discloses a wide-spectrum display covering visible light to infrared bands, which is composed of arrayed display units, and its positional relationship from top to bottom is a second electrode (9), a hydrophobic insulating layer (8), and a fluid chamber chamber (2), barrier layer (6), dielectric layer (5), first electrode (4), substrate (3), lighting layer (14), and the two ends of the peripheral drive circuit (13) are respectively connected to the first electrode ( 4) and the second electrode (9). Utilizing the localized plasmon resonance effect of plasmonic nanoparticles, when the distance between the nanoparticles changes, the peak of the spectral spectrum moves, thereby changing the color of the display unit and realizing the dynamic tunable spectrum. The display has fast response speed, can be used as a microdisplay, and can be applied to anti-counterfeit signs; it can also realize flexible display, and has the advantages of low cost, simple manufacturing process, and the like.

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 ...
