LIQUID CRYSTAL DISPLAY DEVICE

摘要

A liquid crystal display device includes: a display unit configured to pixels in a display region, a pixel drive circuit configured to apply voltage to liquid crystals, a memory configured to store therein a setting signal indicating whether to apply voltage to the liquid crystals in the display region, and two switch elements for switching coupling with the pixel drive circuit; and a controller configured to rewrite the setting signal stored in the memory when a mode in which the display unit is operated is switched, between a first mode causing the display unit to perform display output in accordance with a gradation signal generated based on image data, and a second mode causing the display unit to perform display output in accordance with the setting signal stored in the memory.

1. A liquid crystal display device comprising:
a display unit configured to pixels in a display region, a pixel drive circuit configured to apply voltage to liquid crystals, a memory configured to store therein a setting signal at least in one bit indicating whether to apply voltage to the liquid crystals in the display region, and two switch elements of a first switch and a second switch for switching coupling with the pixel drive circuit; and a controller configured to rewrite the setting signal stored in the memory when a mode in which the display unit is operated is switched, between a first mode causing the display unit to perform display output in accordance with a gradation signal generated based on image data in the case of turning on one of the two switch elements, and a second mode causing the display unit to perform display output in accordance with the setting signal stored in the memory in the case of turning on any one of the two switch elements.
