Display device having memory in pixels

A memory circuit integrated in each pixel of a display device includes a switching circuit and a memory unit. A switching control signal is configured such that in a normal mode, a first transistor of the switching circuit is turned off, while a second transistor of the switching circuit is turned o...

Beschreibung
Zusammenfassung:	A memory circuit integrated in each pixel of a display device includes a switching circuit and a memory unit. A switching control signal is configured such that in a normal mode, a first transistor of the switching circuit is turned off, while a second transistor of the switching circuit is turned on, so that a storage capacitor is electrically coupled to a liquid crystal capacitor in parallel and the memory unit is bypassed. In a still mode, the first transistor of the switching circuit is turned on, while the second transistor of the switching circuit is turned off, so that the storage capacitor controls the memory unit to supply a stored data to the liquid crystal capacitor.
