Driving method of passive display panel and display apparatus

A driving method of a passive display panel, wherein the passive display panel comprises a plurality of pixels arranged into an array, the driving method comprising:

• determining whether to display a first color frame or a second color frame on the passive display panel according to a display frame;
• after the second color frame is displayed on the passive display panel, determining whether to display a first color at each row of the pixels of the passive display panel according to the display frame, and determining whether to display the first color at each column of the pixels of the passive display panel according to the display frame;
• after the first color frame is displayed on the passive display panel, determining whether to display a second color at each row of the pixels of the passive display panel according to the display frame, and determining whether to display the second color at each column of the pixels of the passive display panel according to the display frame;
• displaying the first color column by column or row by row at the pixels of the passive display panel that are corresponding to the first color and do not display the first color;
• and
• displaying the second color column by column or row by row at the pixels of the passive display panel that are corresponding to the second color and do not display the second color,
• wherein the step of displaying the first color row by row or column by column at the pixels of the passive display panel that are corresponding to the first color and do not display the first color comprises:
• when a column number of the passive display panel is greater than a row number of the passive display panel, displaying the first color column by column at the pixels of the passive display panel that are corresponding to the first color and do not display the first color;
• when the column number of the passive display panel is smaller than the row number of the passive display panel, displaying the first color row by row at the pixels of the passive display panel that are corresponding to the first color and do not display the first color;
• and
• when the column number of the passive display panel is equal to the row number of the passive display panel, displaying the first color column by column or row by row at the pixels of the passive display panel that are corresponding to the first color and do not display the first color.
