The present invention concerns a watch (200) or a smart watch (200) having a low power consuming and a bright and enhanced low energy display (100) by using a low energy display (100) configured to display at least one piece of information and to convert at least one primary light (410) into at least one second light (420).

An electronic display device includes measurement sensors that measure respective items, a digital display that displays the items, and a processor. The processor determines a main image related to a measurement of at least one of the items and updates a screen at first timing. Upon displaying the main image related to a measurement of an item other than the first item on the digital display, the processor determines that a sub image is related to measurement of the first item, synchronizes the first timing with update timing that is related to the main image, and simultaneously updates the main image and the sub image.

A method for manufacturing a reflective or transflective liquid crystal display device including a liquid crystal cell whose liquid crystal molecules are aligned in a planar or vertical manner, this liquid crystal cell being formed of a transparent front substrate located on the side of an observer, and a rear substrate, also transparent, which extends under the front substrate, parallel to and at a distance from the latter, these two front and rear substrates being joined together with a sealing frame which delimits a sealed enclosure in which a liquid crystal composition is confined, the front and rear substrates being coated on the opposite faces thereof with electrically conductive transparent electrodes and counter-electrodes, the optical properties of the liquid crystal composition being changed by applying an electric field at the crossing point between an electrode and a corresponding counter-electrode.
