Embodiment Construction

[0056] The pixel unit and its driving method of the present invention are described in detail with reference to the diagrams, and preferred embodiments are given to illustrate the application of the pixel unit in flat-panel displays such as liquid crystal displays or organic electroluminescent displays.

[0057] Please refer to Figure 2A , is that the pixel unit of the present invention is applied to a liquid crystal display. The pixel unit 20 includes at least one data line 21 , at least one scan line 22 , at least one non-volatile memory 23 , at least one storage capacitor 24 and at least one liquid crystal capacitor 25 . The scan line 22 is electrically connected to the gate terminal G of the non-volatile memory 23 . The data line 21 is electrically connected to the source / drain terminal S of the non-volatile memory 23 . The other source / drain terminal D of the non-volatile memory 23 is electrically connected to the storage capacitor 24 and a liquid crystal layer (not sh...

Abstract

The disclosed pixel unit for panel display comprises at least: one non-volatile memory with grid, source and drain electrodes electric connected to a scan line, a data circuit, and a storage capacitor, respectively. Wherein, the opposite drive method comprises: providing a scan voltage and a data voltage to change the initial voltage of the said memory, and then redefining the storage potential of the capacitor.

Description

technical field [0001] The invention relates to a pixel unit of a flat panel display and a driving method thereof, in particular to a pixel unit using a non-volatile memory as an active component and a driving method thereof. Background technique [0002] When an existing display is playing the same static image, for example, when reading an article or an electronic letter, the driver chip must still transmit the same image information to each pixel unit multiple times. In other words, even if the picture is still, the driver chip is still constantly consuming power. However, for portable displays, it is necessary to use lower power consumption to display static images to reduce their charging times. [0003] In order to reduce the power consumption of the display, it is proposed in the prior art to add a memory unit, such as a static random access memory (SRAM), in the pixel unit to achieve the power saving effect when displaying a static image. [0004] Please refer to ...
