Definitions

  • the invention relates to a display device for an electrical appliance with a cover, wherein the cover is colored or colored and has an inhomogeneous transmission profile for light. Furthermore, the invention relates to an electrical appliance with such a display device and a method for controlling such a display device.
  • the color of a visual display also depends significantly on the color or the transmission of the cover.
  • the color of a display can be colored or a desired color can be achieved only to a limited extent, depending on the transmission profile of the cover and the color of the light source.
  • WO 2012/076412 A1 From the WO 2012/076412 A1 is a display device is known in which with three LED primary color lights by appropriate mixing a larger color bandwidth can be created for a display, especially for a white display. On the one hand, however, this is considered to be relatively expensive. On the other hand, a combination of three cooperating LEDs can not be provided for each practically usable display. For example, in so-called seven-segment displays with a height of usually less than 2 cm, this is not practical.
  • the invention is based on the object to provide an aforementioned display device, an electrical device provided therewith and a method for operating such a display device, with which problems of the prior art can be avoided and in particular with differently translucent covers, preferably with reddish-brown Coloring, a white appearing display can be achieved.
  • the cover has an inhomogeneous transmission profile for light with high transmission in the range of wavelengths greater than 700 nm. In the range of wavelengths less than 700 nm, the transmission is lower and can decrease to a maximum of a few percent at significantly less than 700 nm
  • the display device has at least one light source with a defined output spectrum for transmission through the cover of the electrical appliance. In the case of an electrical appliance in the form of a said electric cooktop panel with cooktop panel, the display device or the light source just radiates through this cooktop panel as a cover.
  • the one light source emits white.
  • a further light source is provided.
  • This second light source has such a color or such a chromaticity that when passing through the cover of the electrical device with two light sources together with a coordinated intensity, a white light display is visible as a display or is perceived by a viewer for the sensation of the human eye.
  • the color location of this second light source is to the left of the color location of the first white light source, that is, has a lower value for (x). So can with something increased effort in the form of the second light source, a light in the display device are generated, which looks white after passing through the cover with the aforementioned transmission profile or perceived as white.
  • the first light source and the second light source should just as advantageously be arranged as close to each other as possible, for example, as close as possible their housing, which can be advantageously carried out in SMD technology, as well as their electrical wiring.
  • the color location of the second light source may advantageously have a similar y-coordinate as the color locus of the white first light source.
  • the second light source may have a slightly lower y-coordinate.

  • the combination of the light of this second light source, for example in turquoise, with the white light of the first light source causes a substantially turn turquoise to bluish light. After passing through a said reddish-brown cover, in particular a conventional hob plate of glass ceramic with reddish-brown color, the human eye perceives a white glowing display.
  • a second basic embodiment of the invention according to the preamble of claim 1, only the single light source per display is used, so there is no second light source provided directly next to it, whose light is mixed with the first light source becomes.
  • the color location of this single light source is shifted from white to the left or the x-coordinate of the CIE color locus is smaller.
  • This second light source can thus advantageously have a blue cast or turquoise sting.
  • the light of this single light source appears through an aforementioned cover, especially from reddish-brown glass ceramic, white again to the human eye.
  • the color location of this aforementioned single light source with respect to the y-coordinate is almost the same as that of white light, that is between 0.20 and 0.28, for example, slightly above 0.24.
  • the x-coordinate of its color locus is much further left than for white light, advantageously between 0.1 and 0.2, more preferably about 0.18.
  • the light appears bluish to the human eye.
  • the said single light source can be designed to have a broadband beam, in particular it radiates in the green and blue regions with appreciable intensity.
  • said single light source can have a light spectrum normalized to 1, which has a maximum normalized intensity of 1.0 at a wavelength of 450 nm to 470 nm. In particular, this maximum is about 460 nm. Before the maximum, there may be a steep rise from 0, for example from about 420 nm. Similarly, after the maximum, there may be a steep fall to a relative intermediate low whose normalized intensity is between 0.3 and 0 , 4 lies. It may be at a wavelength between 480 nm and 500 nm, for example at about 490 nm. After the relative intermediate depth, there is a relative intermediate high with a normalized intensity between 0.35 and 0.45, that at a wavelength between 500 nm and 520 nm may be present, in particular at about 510 nm.
  • the normalized intensity drops again, first steep and then flat again.
  • the normalized intensity can be less than 0.1, and at less than 0.01 at a wavelength above 700 nm. This means that this light source has a strong share in the blue area and an intermediate high in the green or turquoise-green area. Red light is barely present in the spectrum.
  • LEDs are generally used as light sources with a semiconductor crystal for the invention.
  • the semiconductor crystals are treated with phosphorus or doped to affect the color.
  • the light sources mentioned for the two basic embodiments of the invention may be formed.
  • the semiconductor crystals can thus be doped with phosphorus as well as treated or doped with other materials in order to produce the desired colors or color spectra.

  • an aforementioned light source which appears white after irradiating the cover, is combined with further light sources.
  • the white radiating light source and one green and one red so a total of three Light sources, so a display device or display with the colors white, green, yellow and red and mixed colors thereof can be created.
  • the bandwidth of these light sources should not be greater than 20 nm, if possible even less than 10 nm.
  • the resulting RGW color space also different mixed colors can be achieved. This will be explained in more detail below with reference to the corresponding figure.
  • the light sources can be controlled with a conventional control for a display, in particular with a hob control.
  • the control only has to be adjusted in its wiring to the changed flux voltage of the light sources.
  • wavelengths or spectra of the wavelength distribution of a single light source or two light sources must be adapted to a cover used. However, by relatively simple experimentation or calculation, these wavelengths can be accurately determined.
