- Display devices can have functions and characteristics of various kinds to display information of all kinds.
- mobile display devices comprising at least a first mobile body, which moves on a dial, so as to be able to indicate information displayed, for example on the dial.
- Such display devices are used to display the time, on watches or clocks. Thanks to mobile rotating hands on a dial presenting, for example, indexes for the hours, the minutes, even the seconds, one can read the time.
- the object of the invention is to remedy the aforementioned drawbacks, and aims to provide a display device which improves readability and aesthetic appearance.
- the invention relates to a mobile display device, in particular for watchmaking, the display device comprising at least a first mobile body and a dial, the first mobile body being configured to move relative to the dial, so as to indicate a plurality of positions on the dial.
- the display device is remarkable in that it comprises a light source arranged to emit light radiation through the dial, and in that the first mobile body comprises a color filter making it possible to modify the color of part of the light radiation passing through the first moving body, so that the first moving body has a color different from the dial.
- the part of the radiation passing through the filter of the first mobile body has a different color from the rest of the light radiation passing through the dial.
- the position of the first mobile body is more readable on the dial, in particular in order to read the time with precision.
- the aesthetics of the display is more attractive for the wearer of the watch, and visible in the dark.
- the color filter is a “notch” type notch filter.
- the light source comprises a discrete spectrum of at least two different colors, preferably three different colors, or even more.
- the discrete spectrum is of the RGB type.
- the source comprises at least two lines of the RGB type, preferably at least three lines.
- the filter has a transmission spectrum configured to block a color of the discrete spectrum of the light source.
- the appearance of the first moving body is variable depending on its position relative to the dial.
- the first moving body moves, it changes color depending on its position, especially because of the discrete spectrum.
- the dial is semi-transparent.
- the display device comprises a protective glass.
- the color of the first movable body is variable depending on its position relative to the dial.
- the display device comprises a color filter arranged on the light source
- the display device comprises means for activating the light source.
- the display device comprises a second mobile body, for example a second needle, the second mobile body comprising a second color filter.
- the invention also relates to a timepiece comprising such a mobile display device.
- FIG. 1 is a schematic representation of a luminous mobile display device according to a first embodiment of the invention
- FIG. 2 is a schematic representation of a luminous mobile display device according to a second embodiment of the invention.
- the invention relates to a luminous mobile display device 1, 10, in particular for watchmaking.
- the luminous mobile display device 1, 10 is that of a timepiece, for example a show.
- the display device 1, 10 comprises in particular a dial 3, 13 and a first movable body 2, 12 which can move relative to the dial 3, 13 to indicate information, for example the time shown by means of a needle arranged above the dial 3, 13.
- the needle is mounted on a rotation shaft 11, which is actuated by a movement 5, 15 of the timepiece 1, 10.
- the movement 5, 10 can for example be a mechanical movement or a quartz movement.
- the display device further comprises a mirror 4, 14 to protect the other parts of the display device 1, 10.
- the mobile display device 1, 10 comprises a dial 3, 13 arranged above the movement 5, 15.
- the display device 1 comprises a light source 8, 18 arranged under the dial 3, 13, the light source 8, 18 being configured to emit light radiation 6, 16.
- the light source 8 is for example a light guide illuminated by an LED-type light-emitting diode 9.
- the light source 8 can be a series of light-emitting diodes, or even a surface OLED, or even an electroluminescent sheet.
- An OLED surface is for example obtained by printing, while an electroluminescent sheet can be produced by evaporation.
- the light source 8 emits the light radiation through the dial 3.
- the dial 3 has a specific color corresponding to that of the light radiation 6 emitted by the light source 8.
- the dial 3 is preferably semi-transparent to allow at least part of the light radiation emitted by the source 8 to pass.
- the peripheral part 6 of the dial 13 is opaque, because the first moving body 12 does not pass over it.
- dial 3 is entirely illuminated by light source 8. [0037] Part of the light radiation 7 passing through the dial 3 through the first moving body 2.
- the first mobile body 2 of the mobile display device 1 comprises a color filter 20.
- the color filter 20 is preferably a “notch” type notch filter. With such a filter 20, it is easy to select the wavelengths to be blocked.
- a first part of the light radiation 7 passes through the dial 3, then the color filter 20 of the first mobile body 2, and finally the crystal 4 to come out of a first particular color.
- the part of the light radiation 7 passing through the dial 3 does not include the color blocked by the filter 20.
- each moving body comprises a color filter, in order to be more visible with respect to dial 3.
- the body filters are different from each other to obtain a different color for each mobile body.
- a second part of the light radiation only passes through the dial 3 before leaving the crystal 4.
- the second part of the light radiation has a second color.
- the second color is different from the first color 7 because it includes the color blocked by the color filter 20.
- the dial 3 transmits the light radiation in the initial color of the light source 8, while the first moving body 2 appears in another color thanks to the color filter 20.
- the part of the light radiation 7 passing through the first mobile body 2 has a modified color compared to that of the dial 3, because the first mobile body 2 includes the color filter 20. Consequently, the contrast between the first mobile body 2 and the dial 13 is greater, and further promotes easy reading of the display. Thus, the visibility of the time is accentuated.
- the display device 1 is preferably provided with means 23 for actuating the light source 8. This prevents the light source 8 from remaining on continuously. Thus, the colors of the first mobile body 2 and of the dial are visible when the actuating means 23 are actuated.
- the actuating means 23 comprise for example a button arranged on the case of the timepiece.
- the light source 18 comprises a discrete spectrum of at least two different colors, preferably three different colors, or even more.
- the discrete spectrum is of the RGB type (for Red, Green, Blue in English).
- the light source 18 comprises several small sources of different colors.
- the light source 18 comprises for example at least two lines of RGB type, preferably at least three lines, which emit multicolored light radiation 16. For example, these lines form a square matrix or concentric circles.
- the first movable body 12 includes a color filter 21 for changing the color of a portion of radiation 17 which passes through the first movable body 12.
- the color filter 21 is preferably a “notch” type notch filter.
- the color filter 21 has a transmit spectrum configured to block a color from the discrete spectrum.
- the color of the first mobile body 17 is different from that of the dial 13. Thanks to the display device according to the invention, the first mobile body 17 has a particular color compared to dial 13. [0052] In addition, when the first mobile body 17 moves, it changes color depending on its position on the dial 13. Thanks to the color filter 21 and the light source 18 with a discrete spectrum, the color of the first movable body 17 is not the same for different positions.
- the part of the radiation 17 which crosses it is variable on the dial 13, so that the first mobile body 12 has a color which changes according to its position on the dial 13. So the color of the part of the radiation 17 which crosses the first mobile body 12 changes according to its position relative to the source 18.
- the body has a particular color different from dial 13, but the color of the first mobile body 12 varies according to its position on dial 13.
- the light 16 emitted by the source is different depending on the position of the dial, because the first body is more or less close to a discrete source of the source light 18.
- the first moving body 12 receives more light of the closest color of the RGB spectrum.
- the display device 20 is preferably also provided with means 24 for actuating the light source 18.
- the display device comprises a second mobile body.
- the moving bodies are for example an hour hand and a minute hand.
