Definitions

  • Timepieces with hybrid display comprising an analog display of the hours and one or more liquid crystal displays, allowing, among other things, the display of calendar functions, moon phases, are well known and we find many different designs on the market.
  • the embodiment described in application CH-B-626 496 comprises a liquid crystal display cell visible through the dial, inside the surface delimited by the hour circle, the front plate of the liquid crystal display cell, the top glass and the polarizer, form the dial.
  • US-A-4,257,115 also mentions a watch, to which calculator functions have been added, provided with a liquid crystal display cell arranged inside the surface limited by the hour circle ; as before, the upper glass and the upper polarizer of the cell are part of the dial.
  • Japanese applications JP-A-59 211 885 and JP-A-58 111 781 each describe a rectangular watch provided with a liquid crystal display cell arranged outside an analog dial of square shape.
  • the top glass and the cell polarizer are part of the dial.
  • Application CH-A-6,974,170 also describes a watch provided with liquid crystal display cells arranged inside the surface limited by the hour circle, the upper glass and the polarizer forming part of the dial.
  • Another object of the invention is to allow modular manufacturing, various semi-products being assembled on demand. Finally, the display plane of the liquid crystal cells being very close to the reading plane of the movement with analog display, the simultaneous reading of the two displays will be facilitated.
  • a liquid crystal display cell 1 comprising successively, for one embodiment of said cell, a lower polarizer 10 ′, a lower glass 11 ′, liquid crystal 12, different electrodes 13 and 13 ′, oriented layers 14 and 14 ′, connections 15, upper glass 11 and an upper polarizer 10.
  • a sealed border 16 ensures the spacing between the electrodes of external connection 17, responsible for transmitting the control signals to the electrodes 13 and 13 ′.
  • control signals of the various liquid crystal display cells originating, in the case where the analog display movement is an electronic movement, from a circuit 4 consisting of an extension of the printed circuit of said movement, comprising the support 40 as well as the tracks 41 connected to the external connections 17 of the liquid crystal display cells 1, by connections flexible "ZEBRA" type 42.
  • the signal control circuit 4 is specific to the liquid crystal display elements.
  • the plate 2 common to the liquid crystal display cells 1 and forming a dial of the clockwork movement with analog display consists of the upper glass 11 as well as the upper polarizer 10 necessary the operation of said liquid crystal display cells.
  • the plate 2 common to the liquid crystal display cells 1 shown in a single copy, and forming the dial of the clockwork movement with analog display 3 is constituted only from the upper polarizer 10, the upper glass 11 being common only to the said liquid crystal display cells and being hollowed out so as to come and surround the part 30 of the clockwork movement with analog display.
  • the plate 2 common to the liquid crystal display cells 1 and forming a dial of the movement with analog display 3 consists only of the upper polarizer 10, the upper glass 11 being specific to each liquid crystal display cell, shown here in a single copy.
  • the polarizer in these two embodiments according to the invention where only the polarizer constitutes the entire dial, said polarizer will be chosen to be more resistant, respectively thicker than a usual type polarizer, in order to ensure sufficient mechanical rigidity for the dial.
  • the upper glass plate 11, common to the various liquid crystal display cells in the first embodiment according to the invention can be made of a material other than glass, according to the method of manufacturing said cells.
  • FIG. 4 shows another embodiment according to the state of the art where there is a superposition of the clockwork movement with analog display 3 and of a liquid crystal display cell 1, of large size and covering roughly the surface of the common plate 2 acting as a dial, except for a central hole intended to allow the moving points 31 to pass.
  • FIG. 5 represents a plan view according to any one of the embodiments according to the invention, with an analog display by hands 32 on a dial 33 and indications by liquid crystal display of the calendar according to a round display 34, of the day of the week according to a crown segment display 35 and of the name of the month according to a vertical right display 36.
  • timepieces with hybrid display whose movement with analog display can be a mechanical or electronic watch of small dimensions, and whose aesthetic effect is obtained by placing said analog display in the center of the dial. and by placing around one or more liquid crystal display elements which may be of any shape, or even be of shapes different from each other; depending on the effect aesthetic sought, the dial is not necessarily circular in shape.
  • Another advantage of an arrangement as proposed is that, the upper polarizer being common to the two types of display, an appreciable reduction in thickness of the assembly is obtained, the movement with analog display being somehow encrusted. among the lower layers of the liquid crystal display element (s).
  • Another advantage of the invention is to be able to constitute sets of finished products according to different variants, on request, from the stock of semi-finished products.
  • the upper polarizer 10 is considered as a first semi-manufactured product, which can be made according to multiple variants of decoration or shape.
  • the part of the plate 2 located under the hands 32 is intended to receive a time marking 33 corresponding to the analog display, this marking being able to be done in any manner known in the art and compatible with the materials used. for the manufacture of plate 2.
  • This plate may also have no marking, the time being read by appreciation of the relative position of the hands 32.
  • a second semi-finished product is made up of liquid crystal display cells arranged according to different variants on their upper glass plate 11, common to the different cells, or according to the other embodiment of the invention, each having its own upper glass plate 11.
  • a third semi-finished product is made up of the clockwork movement with analog display 3, which can also be chosen between different types. It can therefore be seen that, by combining, during assembly, a certain number of variants of the semi-finished products mentioned, it is possible to obtain finished products, on request, according to a relatively high number of variants.
  • the other components of the watch are designed and assembled using known techniques.
  • An additional advantage of an arrangement as presented here stems from the fact that the display plane of the liquid crystal cells is very close to the reading plane of the movement with analog display, thereby facilitating the simultaneous reading of the two displays.
