Embodiment 1

[0024] An embodiment of the present invention provides a display panel, which includes a plurality of pixel regions, and each pixel region has two working states of display and light transmission. In the display working state, the pixel area displays the required color, and in the light transmission working state, the light transmittance of the pixel area is greater than a preset threshold (eg: 90%), realizing transparent display.

[0025] Each pixel area includes a plurality of sub-pixel areas, and in a display working state, the plurality of sub-pixel areas display different colors to combine and display required colors. For example: each pixel area includes a red sub-pixel area, a green sub-pixel area and a blue sub-pixel area, and a required color is displayed by combining three primary colors. Of course, the combination of colors for realizing color display is not limited to the three primary colors of RGB, and may also be other combinations. In the light-transmissive wo...

Embodiment 2

[0075] An embodiment of the present invention provides a display device, which includes the display panel in Embodiment 1, and also includes a plurality of monochromatic light sources emitting light of different colors, and the monochromatic light sources are arranged on one side of the sub-display panel correspondingly. It is used to provide light of a specific color to the corresponding sub-display panel, and the monochromatic light source is arranged close to the side of the optical film layer of the corresponding sub-display panel, so that the sub-pixel regions of different sub-display panels are scattered toward the display side Scattering light of different colors, the area other than the sub-pixel area is in a light-transmitting state, and the sub-pixel area that does not display graphics can also be controlled to be in a light-transmitting state, realizing a transparent color display technology.

[0076] An embodiment of the present invention also provides a method for ...

Abstract

The invention relates to the technical field of display and discloses a display panel and a manufacturing method thereof, a display device and a driving method thereof. The display panel comprises a plurality of sub-pixel areas, each sub-pixel area comprises a plurality of laminated display sub-panels, and each display sub-panel comprises an optical film layer having a light transmitting working state and a light scattering working state. By adopting the display device with the display panel, a transparent state can be achieved during no display by switching the working state of the optical film layer; in the display process, the sub-pixel areas without displaying graphs can also be controlled to be of a transparent state, and a transparent display technology is achieved. Colors of light scattered to the display side by the sub-pixel areas of the different display sub-panels are set, so that color display can be achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof, a display device and a driving method thereof. Background technique [0002] With the continuous increase of market demand, liquid crystal display technology, reflective display technology, and self-luminous display technology have emerged. However, a technology capable of realizing transparent display is lacking. Contents of the invention [0003] The invention provides a display panel and its manufacturing method, a display device and its driving method, which are used to provide a transparent display technology. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a display panel, the display panel includes a plurality of pixel regions, and the display panel includes a plurality of stacked sub-display panels; [0005] Each sub-display panel includes a first base...
