AI Technical Summary

Technical Problem

Existing electronic watches with capacitive or inductive pointing devices face interference issues due to the proximity of display needles, leading to increased electrical consumption and reduced autonomy.

Method used

A display system with a movable element, such as a needle, is positioned above the display device and partially overlaps it, creating an area where the user can interact without disturbing the capacitive or inductive field, thereby reducing energy consumption.

Benefits of technology

This arrangement minimizes interference with the pointing device's field, conserving energy and enhancing the watch's autonomy.

Description

Technical field

[0001] The present invention relates to the field of watchmaking, and more specifically to display systems for displaying information on a dial. Preferably, the present invention relates to the field of watch indicators and preferably connected watch indicators. Technological background

[0002] Recent years have seen the rise of electronic watches, particularly watches with a capacitive or inductive pointing device.

[0003] EP 3321748 A1 discloses a smart watch comprising a display module above which two side hands indicate the time, a haptic module being located on the watch glass. The hands are arranged below the haptic module 15c included in the display module 15a in a peripheral area.

[0004] The user can indicate a function they wish to activate by touching or stroking the screen, which causes a change in the capacitive or inductive field.

[0005] This change in the field is disturbed by the needles which are very close to the screen.

[0006] Existing solutions propose increasing the voltage or current in order to be less sensitive to disturbances, which inevitably leads to an increase in the consumption of electrical energy and therefore reduces the autonomy of the electronic watch. Summary of the invention

[0007] The present invention proposes to resolve all or part of the drawbacks mentioned above by means of a display system for a watch comprising at least: a display device; said at least one display device being configured to display information; a pointing device; said at least one pointing device, preferably capacitive or inductive, being arranged above said at least one display device; said at least one display device and said at least one pointing device defining an overlap area allowing the user to point said information from said at least one display device to said at least one pointing device; a movable element; said at least one movable element being arranged totally or partially above said at least one display device and at the periphery of said overlap area, said at least one movable element being configured to be movable around said overlap area.

[0008] According to the invention, said at least one mobile element is excluded from said overlap zone. Thanks to this arrangement, said at least one mobile element cannot interfere with the capacitive or inductive field of said at least one pointing device.

[0009] According to one embodiment, said overlapping area comprises at least 60%, preferably at least 85%, in particular 95% of said at least one display device.

[0010] By virtue of this arrangement, said overlapping area only partially covers said at least one display device, which leaves space for said at least one movable element.

[0011] According to one embodiment, said at least one movable element is an indicator, preferably a needle. Brief description of the figures

[0012] The invention will be described below in more detail with the aid of the appended drawings, given as non-limiting examples, in which: There figure 1 illustrates a watch comprising a display system according to one embodiment of the invention; The figure 2 shows a sectional view of the display system of the embodiment of the figure 1 . Detailed description of the invention

[0013] There figure 1 represents a watch 200 with a display system 100 according to the invention. Said display system 100 for the said watch 200 has at least one display device 110, preferably LCD or even OLED, configured to display information, from at least one pointing device 120, preferably capacitive or inductive depending on the embodiments, arranged above said at least one display device. Said at least one display device 110 and said at least one pointing device 120 define an overlap area 130,representing at least 60%, preferably at least 85%, in particular 95% of said at least one display device 110, allowing the user to point at said at least one pointing device 120 said information of said at least one display device 110, as shown on the figure 2 .

[0014] In fact, the said overlap area 130 defines a display 133 between said at least one display device 110 and said at least one pointing device 120 allowing the user to select one or more functions or information that would be displayed.

[0015] Added to this is at least one moving element 140, which may take the form of an indicator, preferably a needle 140, and being movable around said overlapping area 130. Said at least one movable element 140can be arranged totally or partially above said at least one display device 110 and on the periphery of said at least one pointing device 120 so as to be on the periphery of said overlap zone 130, as shown on the Figures 1 and 2 . Thus said at least one mobile element 140 cannot interfere with the capacitive or inductive field of said at least one pointing device 120.

[0016] Said at least one movable element 140 is excluded from the said recovery zone 130 so as to prevent said at least one moving element 140 does not interfere with the capacitive or inductive field of said at least one pointing device 120.

[0017] Thus, the user can indicate a function that he wishes to activate by making contact with said at least one pointing device. 120by touching or stroking, which causes little or no modification of the capacitive or inductive field.

[0018] Furthermore, the display system 100 according to the invention makes it possible to reduce the consumption of electrical energy and therefore increases the autonomy of the electronic watch.
