Abstract
A display device includes a plurality of pixels arranged in a matrix with columns and rows. A source driver provides either analogue or digital image data for the pixels. Each pixel includes a plurality of sub-pixels. Each sub-pixel includes a display components, a memory unit for memorizing gradation display data included in the digital image data provided by the source driver for the display component, and a data switching unit for switching data providing for the display component to either the gradation display data memorized in the memory unit or the analogue image data provided by the source driver.
Claims10
An active matrix display device, comprising:
- a plurality of pixels arranged in a matrix with columns and rows;
- and
- a source driver configured to provide either analogue image data or digital image data for the plurality of pixels, wherein
- each of the plurality of pixels comprises a demultiplexer configured to divide the digital image data provided by the source driver into a plurality of bits representing gradation display data, and
- each of the plurality of pixels comprises a plurality of sub-pixels, and each of the plurality of sub-pixels comprises:
- a display component;
- a memory unit configured to memorize the gradation display data provided by the demultiplexer for the display component;
- and
- a data switching unit directly connected to the memory unit and a source line of the source driver, the data switching unit configured to switch data provided for the display component to either:
- the memorized gradation display data in the memory unit, or
- the analogue image data provided by the source driver.
