Example Embodiment

[0029] An embodiment of the present invention provides a display panel, as attached figure 1 As shown, it may specifically include an upper substrate 1, a lower substrate 2, and a polymer dispersed liquid crystal (PDLC) layer 3 located between the two substrates;

[0030] as well as:

[0031] A color film layer 4 for presenting primary colors between the upper substrate 1 and the PDLC layer 3, and the color film layer 4 is filled with electrochromic materials;

[0032] The transparent electrode layer used to control the PDLC layer 3 to present different gray levels and to control the color film layer 4 to present primary colors by applying voltage (ie attached figure 1 Reference numerals 51, 52, 53 in the middle).

[0033] The implementation of the display panel provided by the embodiment of the present invention can effectively increase the light transmittance of the color PDLC display panel, and improve the display quality of the color PDLC display panel.

[0034] The working principl...

Abstract

The invention provides a display panel and a display device. The display panel is provided with an upper substrate, a lower substrate, a polymer dispersed liquid crystal (PDLC) layer between the upper substrate and the lower substrate, and a colorful film for displaying primary color; the colorful film layer is arranged between the upper substrate and the PDLC layer; and an electrochromatic material is filled in the colorful film layer. By applying voltage, the PDLC layer is controlled to display different gray levels and a transparent electrode layer controls the color film layer to display the primary color, so as to effectively improve the light transmittance of the PDLC display panel and further improve the display quality of the colorful PDLC display panel.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and in particular may relate to a display panel and a display device. Background technique [0002] Polymer dispersed liquid crystal (PDLC) display panels have good application prospects in the field of transparent and flexible displays because they do not require polarizers and alignment layers, are easy to manufacture, and can realize flexible displays. [0003] The PDLC layer is a mixture of small-molecule liquid crystals and prepolymers, and undergoes a polymerization reaction under certain conditions to form micron-sized liquid crystal droplets that are evenly dispersed in the polymer network, and then use the dielectric anisotropy of liquid crystal molecules to obtain A material with electro-optic response characteristics, it mainly works between the scattering state and the transparent state and has a certain gray scale. [0004] In the existing color PDLC display p...
