摘要： A watch includes a crystal oscillator, a controller including an oscillation circuit configured to cause the crystal oscillator to oscillate, wiring that couples the crystal oscillator with the controller, and the crystal oscillator, a storage container that stores the crystal oscillator, the wiring, and the controller, and an outer case that stores the storage container, in which the crystal oscillator and the controller are placed side by side inside the storage container in plan view.

摘要： An adjustment phase, a clearing phase, and a gray level control phase are used when changing the gray levels of pixels. A plurality of pixels are aligned to a predetermined gray level in the adjustment phase. In the adjustment phase, the gray level of a pixel is changed earlier the greater a gray level difference between the gray level of the pixel and the predetermined gray level is.

摘要： In a refresh period, a voltage for alternatingly inverting a memory display element between a first gray level and a second gray level is applied. The number of inversions in the refresh period when the temperature of the memory display element is low is lower than the number of inversions in the refresh period when the temperature of the memory display element is high.
