Problems solved by technology

[0004] Since the image display must involve the display of color images, the traditional display panel is realized by using a color film substrate. This display method cannot be selectively switched between color and black and white.

Embodiment 1

[0033] This embodiment provides a display panel, including: a display unit for displaying, preferably, the display unit is any one of a liquid crystal display unit, an organic light emitting diode display unit, and a plasma display unit. In this embodiment, the liquid crystal display unit is taken as an example for introduction, such as figure 1 As shown, the liquid crystal display unit (the liquid crystal display unit in the present invention mainly provides black and white display) includes a plurality of pixel units 13; the pixel unit 13 includes: a glass substrate 1, on the light emitting side of the glass substrate 1 ( The incident direction of light indicated by the three arrows in the figure) the common electrode 10 , the insulating layer 3 , the pixel electrode 9 , and the liquid crystal layer 8 are arranged in sequence. The liquid crystal layer 8 includes alignment layers 7 located on both sides of the liquid crystal layer 8 .

[0034] The display panel also includes...

Embodiment 2

[0066] This embodiment provides a display device, which includes the above-mentioned display panel.

[0067] Different from Embodiment 1, the angle of the two polarizers 14 is always 90°

Abstract

The invention provides a display panel and a display device, belonging to the field of display technology, which can realize selective switching between color transparent display and black and white transparent display. The display panel and the display device of the present invention include: a display unit for displaying, the display unit includes a plurality of pixel units; a color changing unit corresponding to the positions of the pixel units of the display unit, the The color changing unit is made of electrochromic material; the color control unit is used to control the color change of the color changing unit. The display panel and the display device of the present invention adopt a novel color-changing unit, which realizes the selective switching between color transparent display and black-and-white transparent display of the display panel and display device.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a display device including the display panel. Background technique [0002] With the increasing demand for information displays, in flat panel displays, liquid crystal displays that use the optical anisotropy of liquid crystal molecules to display images are widely used for their excellent resolution, color display and image quality. [0003] Since the display panel can not only realize image display, but also make objects on its back visible, so transparent display has become the focus of research. Such display panels can be applied to vehicle windshields and house glass to provide information required by users. [0004] Since image display inevitably involves the display of color images, traditional display panels are implemented using color filter substrates, which cannot be selectively switched between color and black and white. Therefore, i...
