Embodiment 1

[0041] An embodiment of the present invention provides a digital window, the digital window includes at least three electrode layers and at least two PDLC film layers, and is used to display preset content.

[0042] Optionally, the digital window is set as a rectangle, such as figure 1 As shown, it includes: the first electrode layer A1, the first PDLC thin film layer B1, the second electrode layer C, the second PDLC thin film layer B2 and the third electrode layer A2 are sequentially arranged from bottom to top; wherein,

[0043] The first electrode layer A1 includes a first preset number of electrode sheets arranged in M ​​rows in the longitudinal direction; M is a positive integer; the first preset number is the number of each column;

[0044] The third electrode layer A2 includes a second preset number of electrode sheets in N columns arranged in the short side direction; N is a positive integer; the second preset number is the number of each row;

[0045] The sides of t...

Embodiment 2

[0052] The embodiment of the present invention provides a digital window, such as figure 2 As shown, the digital window is a 4*5 matrix display unit ( figure 2 As shown in figure c), the digital window includes the first electrode layer A1 ( figure 2 shown in figure a) and the third electrode layer A2 ( figure 2 shown in Figure b). The first PDLC film layer, the second PDLC film layer and the second electrode layer C ( figure 2 (not shown in ) refer to Embodiment 1, and will not be introduced here.

[0053] It should be noted that the digital window in the embodiment of the present invention is designed according to a commonly used rectangle, so the five layers of materials constituting the digital window are also rectangular. Wherein, the long side direction refers to the straight line where the long side of the rectangle is located, and the short side direction refers to the straight line where the wide side of the rectangle is located.

[0054] In the embodiment o...

Embodiment 3

[0070] The embodiment of the present invention also provides a digital window, such as Figure 5 As shown, the digital window is a 4*5 matrix display unit ( Figure 5 As shown in Figure c), this digital window has the same structure as the digital window provided in the embodiment, the difference is that: the first electrode layer A1 is etched 4 times in the long side direction to form 5 electrode sheets, and then from Divide each obtained electrode sheet into two equal electrode sheets in the direction of the broad side, and finally get the following Figure 5 For the 10 electrode sheets shown in the figure a, the first column is coded as 21-25, and the second column is coded as 26-30. The third electrode layer A2 is etched three times in the widthwise direction to form four electrode sheets, which are sequentially coded as 31-34. The common electrode 35 is connected to the second electrode layer C. Finally, the first electrode layer A1 is overlapped with the third electro...

Abstract

The invention relates to a digital window and a display device. The digital window comprises at least three electrode layers and at least two PDLC thin film layers for displaying a preset content in a matrix display manner when preset voltages of at least three electrode layers are input. The display device provided by the invention comprises the digital window. The digital window is a forward mode or a backward mode and can separately show full-on, full-off, digital, partial alphabet and prompt display under special logic.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a digital window and a display device. Background technique [0002] The device formed by polymer and liquid crystal droplet dispersion has a history of more than 50 years, and has developed into a professional technical field of the liquid crystal industry. Cholesteric liquid crystals are mixed for thermochromic displays or electrochromic displays. In the 1980s, Fergason invented the liquid crystal droplet dispersion system with polyvinyl alcohol aqueous solution and positive nematic liquid crystal. Adding dyes to liquid crystals) as the mechanism of light valves and displays. Kent State University invented the method of mixing polymer monomers or prepolymers with positive nematic liquid crystals to form a homogeneous solution. In the large process, it is gradually separated into a droplet dispersion system, and named PDLC (Polymer Dispersed Liquid Crystal) polymer dispersed...
