A radio-controlled wristwatch limits week information reception to reduce power consumption.
A color-coded analog clock visualizes daily light conditions to support interactive activity scheduling.
A liquid crystal control circuit manages enable signal output periods to prevent interference with VCOM inversion signals.
An electronic timepiece applies daylight saving rules based on current position using pre-stored area data and radio wave reception.
A segmented storage system manages additional city data within an electronic timepiece.
An electronic timepiece calculates local times for main and sub clocks using current position data.
A timing controller inserts black display periods before mode transitions, allowing the power supply unit to gradually adjust voltage and prevent flashing.
Adjusting signal generator drive capability by wire length compensates for resistance-induced voltage blunting, ensuring uniform brightness and chromaticity.
