Display system and driving method

A display system comprising:

• a display panel having a plurality of display pixels arranged in display rows and display columns, each of the display pixels comprising two sub display pixels arranged along a row direction such that any consecutive three of the sub display pixels in either the row direction and a column direction display a combination of a first color, a second color and a third color;
• a driving device comprising:
• a mode detection circuit configured to receive a first image frame from a video source and to determine whether a predetermined condition of the first image frame is met;
• a one dimensional (1-D) sub-pixel rendering circuit configured to receive a second image frame having a plurality of data pixels arranged in data rows and data columns from the video source and to generate a plurality groups of first display pixel values each generated for one target data pixel based on the data pixels neighboring the target data pixel within a same one of the data rows when the predetermined condition is not met;
• and
• a two dimensional (2-D) sub-pixel rendering circuit configured to receive the second image frame from the video source and to generate a plurality groups of second display pixel values each generated for one target data pixel based on surrounding data pixels in the neighboring data rows and the neighboring data columns when the predetermined condition is met;
• wherein either the groups of the first display pixel values or the groups of the second display pixel values are generated to be outputted to the display panel and are displayed by the display pixels.
