摘要： The present invention provides a lens (5) at least comprising a transparent liquid with quantum dots (6) suspended therein, wherein the quantum dots transmit visible light of a longer wavelength than they receive. A surface profile of the transparent liquid may be changed in shape using the principle of electrowetting by electrically connecting electrodes (7) to the lens, so that one or more optical properties of the lens may be dynamically altered during the transmission of light thereby. The quantum dots (6) suspended in the transparent liquid can be used to down-convert the wavelength of light transmitted through the lens, and any of the shape, size, composition and concentration of the quantum dots may be varied to modify the optical properties of the lens, and in particular to modify the colour gamut of light transmitted by the lens. Thus, for example, the liquid lens (5) can be combined with a blue LED (2) in a light emitting electronic device, and the quantum dots (6) can be chosen to have a size distribution comprising two peaks configured to transmit light at green and red wavelengths. The blue light (3) emitted by the LED (2) can therefore be down-converted by the quantum dots (6) within the lens to provide green and red light, which mix with the blue light (3) from the LED to provide white light (4) with a high colour gamut. The present invention also provides a method of manufacturing such a lens, a method of operating a light emitting electronic device comprising such a lens, as well as a backlight for a display screen comprising a plurality of such light emitting electronic devices, and a luminaire also comprising a plurality of such light emitting electronic devices. Both the backlight for a display screen and the luminaire may therefore have their optical properties dynamically altered during emission of light thereby.

摘要： The present invention provides a lens (5) at least comprising a solidified droplet of a transparent liquid doped with quantum dots (6), wherein the quantum dots transmit (4) visible light of a longer wavelength than they receive (3). The transparent liquid can be used to manufacture the lens in an inkjet material deposition process, whereby the lens can be provided with any shape as desired, and the design of the lens may also be quickly and easily changed during the manufacturing process with little cost or delay. The quantum dots with which the transparent liquid is doped can be used to down-convert the wavelength of light transmitted through the lens, and the shape, size, composition and concentration of the quantum dots may also be quickly and easily altered to modify the optical properties of the lens, and in particular to modify the colour gamut of light transmitted by the lens. The lens (5) may be a component part of a light emitting electronic device further comprising an LED (2), mounted on a substrate (1). The LED may, for example, be a blue LED and the quantum dots (6) may have a size distribution comprising two peaks configured to transmit light at green and red wavelengths, so that light (3) from the LED (2) is down-converted by the quantum dots (6) into light of longer wavelengths and mixes with the blue light (3) from the LED to provide white light (4) with a high colour gamut. Furthermore, a plurality of such LED devices may be incorporated into a backlight for a display, such as a video display screen. This has the advantages of providing the display with more even illumination and a wider colour gamut of light transmitted by the lens than previously. The present invention also provides a method of manufacturing a lens, wherein the method comprises doping a transparent liquid with quantum dots which transmit visible light of a longer wavelength than they receive, spraying the liquid as droplets from a nozzle of an inkjet printer onto a substrate, and curing the liquid to solidify the droplets.
