Embodiment Construction
[0038] The present invention will be described in detail below in conjunction with examples, which are only preferred implementations of the present invention, and are not limitations of the present invention.
[0039] like figure 1 As shown, the present invention provides a PDLC display panel 1, which includes an upper substrate 11 and a lower substrate 12 arranged oppositely, a conductive layer 13 respectively arranged on the lower side of the upper substrate 11 and the upper side of the lower substrate 12, The polymer dispersed liquid crystal layer 15 interposed between the upper substrate 11 and the lower substrate 12 ; and an AR film 14 respectively disposed on the upper side of the upper substrate 11 and the lower side of the lower substrate 12 . Each of the AR films 14 includes at least one layer of optical film, which may be one or more layers of optical film, so that the substrate (upper substrate 11 or lower substrate 12) has a higher transmittance in the visible lig...

Abstract
The invention discloses a PDLC (polymer dispersed liquid crystal) display panel and a manufacture method thereof; the PDLC display panel comprises an upper substrate and a lower substrate arranged face to face, conductive layers arranged below the upper surface and above the lower surface respectively, and a polymer dispersed liquid crystal layer arranged between the upper substrate and the lower substrate; the PDLC display panel also comprises AR (antireflective) films arranged above the upper substrate and below the lower substrate respectively. The upper and lower high-transmittance substrates with the outer surfaces coated with high-performance AR films in the PDLC display panel help inhibit surface reflection, reduce light loss of the substrates, improve the transmittance thereof, and improve light availability, thereby improving on-state transmittance of a display; compared with those with AR film on single side, the PDLC display panel has the advantages that transmittance can be improved to greater extent and an object viewed through glass in transparent state is clearer.
Description
technical field [0001] The invention relates to the technical field of PDLC display, in particular to a PDLC display panel and a manufacturing method thereof. Background technique [0002] Compared with traditional LCD display devices, polymer-dispersed liquid crystal (PDLC) displays have many advantages, such as no need for polarizers, high brightness, wide viewing angle, and no need for liquid crystal alignment layers. Therefore, in the preparation of soft, high brightness, Large-area liquid crystal displays with wide viewing angles have broad application prospects. [0003] Generally, the improvement of the contrast of the PDLC display is mainly achieved by increasing the on-state transmittance and reducing the off-state transmittance. There are two main ways to reduce the off-state transmittance: first, reduce the dark-state transmittance by increasing the film thickness, but the driving voltage of PDLC also increases with the increase of thickness; 2. Improve the prep...
