Display panel display device including the display panel and method for driving the display panel

摘要

The embodiment of the present invention discloses a display panel, a method for driving the display panel and a display device provided with the display panel, which belong to the field of display technology and solve the technical problems that the existing AMOLED has relatively high power consumption and thus has difficulty in meeting current energy-saving requirements on the display panel. The display panel includes a plurality of pixel units arranged in an array and each pixel unit includes at least one OLED sub-pixel and at least one EPD sub-pixel. The present invention can be applied in scenes such as a transparent window and a refrigerator door.

主权项

1. A display panel comprising:
a plurality of pixel units arranged in an array; means for determining a color to be displayed by a pixel unit, wherein each pixel unit consists of three OLED sub-pixels and one EPD sub-pixel, wherein if the color to be displayed by the pixel unit is the same as that of the EPD sub-pixel, driving the EPD sub-pixel to display; otherwise, driving the three OLED sub-pixels to display, wherein in the case that each pixel unit of the display panel includes three OLED sub-pixels and one EPD sub-pixel, and the three OLED sub-pixels are a red OLED sub-pixel, a green OLED sub-pixel and a blue OLED sub-pixel, respectively, and the one EPD sub-pixel is a black-and-white EPD sub-pixel, said means for determining a color to be displayed by the pixel unit further includes means for acquiring three gray values of respective red, green and blue components of the color to be displayed by the pixel unit, wherein if two of the three gray values are different, determining that the color to be displayed by the pixel unit is a color other than black and white, and wherein if all of the three gray values are identical, determining that the color to be displayed by the pixel unit is black-and-white.
