Title:
Display device
Document Type and Number:
Japanese Patent JP6122053
Kind Code:
B2
Abstract:
The liquid crystal display device includes a pixel portion including a plurality of pixels to which image signals are supplied; a driver circuit including a signal line driver circuit which selectively controls a signal line and a gate line driver circuit which selectively controls a gate line; a memory circuit which stores the image signals; a comparison circuit which compares the image signals stored in the memory circuit in the pixels and detects a difference; and a display control circuit which controls the driver circuit and reads the image signal in accordance with the difference. The display control circuit supplies the image signal only to the pixel where the difference is detected. The pixel includes a thin film transistor including a semiconductor layer including an oxide semiconductor.
