A sequential displaying method is provided. The method includes providing a display device which includes a first display area. The first display area has N first sub-areas that are arranged in sequence, wherein N is positive integer. Then, displayed images in the N first sub-areas are sequentially updated, wherein a time interval of updating the displayed images in two adjacent first sub-areas is 60/N seconds and a frequency for updating a displayed image in each of the first sub-areas is once every 60 seconds. Thus, a method for displaying time information could be improved.

A smart watch, which simultaneously provides the two functions of a physical watch and a mobile terminal, and a method for controlling the same are disclosed. The present invention provides a smart watch and a method for controlling the smart watch, the smart watch comprising; a case; at least one hand for displaying current time, the at least one hand being arranged to be adjacent to the inner periphery of the case; a movement for moving the hand along the inner periphery of the case, the movement being located inside the case; and a display unit configured to display various types of information, the display unit being located in the case, wherein the hand and a screen of the display unit are simultaneously shown to a user.

Aspects of the technology provide a symbiotic graphical display on a client device such as a smartwatch. The system includes at least one emissive display element and at least one non-emissive display element. The display elements are arrayed in layers or other configurations such that content or other information is concurrently aligned across the respective display surfaces of the different elements. A first set of content is rendered using the non-emissive display element while a second set of content is rendered using the emissive display element. Depending on characteristics or features of a given content item, that item may be rendered by one or both of the display elements. Certain content may be transitioned from the emissive display element to the non-emissive display element according to a time threshold or other criteria.

Light guide into which is injected the light produced by a light source optically coupled to the light guide, wherein the light guide includes a first central portion made of a transparent material in which are structured light extractors, via which the light produced by the light source is extracted from the light guide, and a second peripheral portion made of a light absorbing material and surrounding the central portion, wherein the peripheral portion is integral with the central portion.

A display device including a liquid crystal cell (2) formed from two transparent plates (4, 6) defining a useful zone (12), designed to define the visible zone of the cell in a timepiece, and incorporating electrodes forming a switchable display of an item of information and/or a decoration in the useful zone. The liquid crystal cell (LCD cell) includes, in the useful zone, a plurality of polarisers (16, 18) which are arranged on the outer surface (5) of one of the two transparent plates respectively in a plurality of separate zones (17, 19) and which each partially form the switchable display. At least two polarisers in the plurality of polarisers have a different optical property or a different polarisation direction between them. The device generates visually a variation between respective parts of the two polarisers and/or respective parts of the switchable display in the respective separate zones.
