Watch bands described herein include electrochromic features that provide adjustable color control based on an applied voltage to offer a variety of colors and color combinations to be displayed by a single band. The user or a control system can control, select, and/or adjust one or more colors of the watch band for visual display. Accordingly, a variety of colors can be displayed at different times without requiring different watch bands for each color or color combination. The color changing features can be used as a visual output of information from the watch to the user.

A clock that runs along a path while lighting elements along the path. Each element along the path can be lit in a different color. One of the colors represents hours one represents minutes and the other represents seconds. Values which are lit continually change as times change, but this allows an artistic display of time.

In the case where a ticking timing of a clock unit changes, a CPU of an electronic timepiece outputs a synchronization request signal to a CPU of a display module at the next ticking timing after the change so as to request resynchronization. Each time a timer circuit counts a prescribed number of pulses in a clock signal generated by a clock generation circuit on the basis of the ticking timing, the CPU of the display module instructs a liquid crystal driver circuit to invert the polarity of an AC voltage to be applied to a liquid crystal panel. Moreover, upon receiving the synchronization request signal from the CPU of the electronic timepiece, the CPU of the display module sets the timer circuit to start a new count of the clock.

An electronic device includes: a TFT liquid crystal panel; a light source that emits light to be radiated onto a back face of the TFT liquid crystal panel; and a processor that generates a common signal to be input to a common electrode of the TFT liquid crystal panel. The processor generates the common signal so as to have a waveform that differs between when the light source is not lit and when the light source is lit.

This application relates to a wearable electronic device including a housing having an illumination region, where the housing can carry components that can include a processor capable of receiving an input signal and responding to the input signal by providing an illumination signal. The components can further include independently-controllable light-emitting units carried by the housing at the illumination region and in communication with the processor, the light-emitting units capable of (i) receiving the illumination signal from the processor, and (ii) presenting the notification by emitting an amount of light in accordance with the illumination signal.

An electronic apparatus comprising an electro-luminescent display device, an information display window defined on an outward facing surface of the display device to form a data display portion having a characteristic pixel density, a digital assembly to output data to the display device for display on the information display window, a viewing window through which information displayed on the information display window is viewable from outside of the apparatus, and a translucent plastic light filter disposed between the viewing window and the information display window; wherein the translucent plastic filter has a transmittance which is adapted to visually conceal the information display window or make the underlying information display window not visible when under sunlit ambient illuminations.

Disclosed are a display method, a wrist-worn device and a computer-readable storage medium. The display method is applied to the wrist-worn device. The display method includes: emitting, via a light source, a first detection light; receiving, via a light identification unit, the second detection light formed by the first detection light and identifying the light parameter of the second detection light, wherein the light parameter of the second detection light carries the style information of the wristband; reading, via the controller, the style information and generating a screen display control signal according to the style information; and controlling, via the controller, the display unit on the device body to display a corresponding display mode according to the screen display control signal.
