CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority benefit of Taiwan application serial no. 109135129, filed on Oct. 12, 2020. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.

BACKGROUND

Technical Field

The disclosure relates to a circuit and a device, and particularly relates to a pixel circuit and a display device.

Description of Related Art

The conventional pixel circuits or display devices may only selectively operate in the static mode or the dynamic mode, and the users are unable to switch the operations of the pixel circuits or the display devices according to requirements. Therefore, when the pixel circuits or the display devices are only allowed to operate in the static mode, the pixel circuits or the display devices are unable to display images of a high quality. Comparatively, when the pixel circuits or the display devices are only allowed to operate in the dynamic mode, the pixel circuits or the display devices are unable to carry out power-saving operations.

SUMMARY

The disclosure provides a pixel circuit and a display device switchable to operate in a static mode and/or a dynamic mode.

The pixel circuit of the disclosure is configured to drive a light emitting diode. The pixel circuit includes a storage capacitor, a selector, a memory device and a write switch. The storage capacitor is coupled to the light emitting diode. The selector selects a first signal or a second signal to the storage capacitor according to a stored data. The memory device is coupled to the selector. The memory device stores a written data to obtain the stored data. The write switch is coupled to the memory device. The write switch writes in the written data to the memory device while the pixel circuit is in transition of operation modes.

The display device of the disclosure includes multiple data lines and multiple pixel circuits. The pixel circuits are respectively coupled to the corresponding data lines. Each of the pixel circuits is configured to drive a light emitting diode, and the each of the pixel circuits includes a storage capacitor, a selector, a memory device and a write switch. The storage capacitor is coupled to the light emitting diode. The selector selects a first signal or a second signal to the storage capacitor according to a stored data. The memory device is coupled to the selector. The memory device stores a written data to obtain the stored data. The write switch is coupled to the memory device, and the write switch writes in the written data to the memory device while the pixel circuits are in transition of operation modes.

Based on the above, the pixel circuit and the display device may be switched to operate in the static mode and/or the dynamic mode. In this way, the operations of the pixel circuit and the display device may be adaptively switched according to different usage requirements.

To make the aforementioned more comprehensible, several embodiments accompanied with drawings are described in detail as follows.
