Problems solved by technology

[0005] However, the light transmittance of the color dye filled in the dye layer of the existing color PDLC display panel is usually only 25-30%, and the color display that combines the dye layer with the PDLC layer will further reduce the transmittance.

Embodiment Construction

[0029] A display panel provided by an embodiment of the present invention, 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 between the two substrates;

[0030] as well as:

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

[0032] It is used to control the PDLC layer 3 to present different gray scales and the transparent electrode layer (that is, attached figure 1 Indicated by reference numerals 51, 52, 53).

[0033] The realization of the display panel provided by the embodiment of the present invention can effectively improve the light transmittance of the color PDLC display panel, thereby improving the display quality of the color PDLC display panel.

[0034] The working principle of the PDLC layer involved in the embodiment of t...

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...
