Abstract

The invention discloses a display panel, a display device and a driving method of the display panel. The display panel comprises a first liquid crystal module and a second liquid crystal module which are arranged in a stacked mode, wherein the first liquid crystal module comprises a first substrate, a first liquid crystal layer and a second substrate which are stacked in sequence; the first liquid crystal layer reflects or scatters light of different wavebands under the action of an electric field generated between the first substrate and the second substrate; the second liquid crystal module comprises a backlight module, a third substrate, a second liquid crystal layer and a fourth substrate which are sequentially stacked; the second liquid crystal layer controls the transmittance of emergent light of the backlight module under the action of an electric field generated between the third substrate and the fourth substrate; and the first liquid crystal module is located on the side, away from the backlight module, of the fourth substrate, and transmission display and reflection display are achieved.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a display panel, a display device and a driving method for the display panel. Background technique [0002] Currently, a Liquid Crystal Display (LCD) has become a mainstream display in the market. Along with the development of liquid crystal displays, people's requirements for liquid crystal displays are getting higher and higher. Traditional LCD panels have the advantages of good image quality, light weight, low power consumption, and small size. [0003] As technology matures, people's needs are also increasing. Ordinary e-books and blackboards can only display monochrome, and displays that cannot achieve mixed color or white display and have a single display function can no longer meet market demand. Contents of the invention [0004] Embodiments of the present invention provide a display panel, a display device, and a driving method for the display panel, s...
