Example Embodiment

[0028] Example 1:

[0029] A double-sided display panel includes a first display subunit and a second display subunit that are arranged opposite to each other. A dye base layer is also arranged between the first display subunit and the second display subunit. The dye base layer can make the first display subunit and the second display subunit display colors at the same time.

[0030] Such as image 3 As shown, the first display subunit includes a first common electrode layer 12, a first polymer dispersed liquid crystal layer 14 and a first array substrate 16 which are arranged in sequence, and the second display subunit includes a second common electrode layer 12 which is arranged in sequence. The electrode layer 13, the second polymer dispersed liquid crystal layer 15 and the second array substrate 17 are provided with a dye base layer 18 between the first common electrode layer 12 and the second common electrode layer 13.

[0031] Among them, such as image 3 As shown in B, the dy...

Example Embodiment

[0048] Example 2:

[0049] The difference between this embodiment and Embodiment 1 lies in that the liquid crystals in the first polymer dispersed liquid crystal layer and the second polymer dispersed liquid crystal layer of the double-sided display panel in this embodiment are both positive liquid crystals.

[0050] In this embodiment, the positive PDLC layer is in a transparent state when there is an electric field, and is in a scattering state when there is no electric field. Specifically, when an electric field is applied, the liquid crystal molecules are regularly arranged parallel to the electric field, and the refractive index of each liquid crystal molecule is matched. At this time, the PDLC layer is in a transparent state and displays a bright state; when there is no electric field, the liquid crystal molecules are arranged irregularly. The refractive index of the liquid crystal molecules is anisotropic. At this time, the PDLC layer is in a scattering state, showing a dark...

Example Embodiment

[0053] Example 3:

[0054] The difference between this embodiment and Embodiments 1 and 2 lies in the fact that one of the liquid crystals in the first polymer dispersed liquid crystal layer and the second polymer dispersed liquid crystal layer of the double-sided display panel in this embodiment is negative liquid crystal and the other is Positive liquid crystal.

[0055] In this embodiment, the working state analysis of the negative PDLC layer and the positive PDLC layer under the action of an electric field and without an electric field respectively refer to Embodiments 1 and 2, which will not be repeated here.

[0056] A double-sided display device including the above-mentioned double-sided display panel.

[0057] The other structures of the double-sided display panel and the double-sided display device in this embodiment are the same as those of the first embodiment, and will not be repeated here.

[0058] Embodiments 1-3 provide a double-sided display panel and a double-sided dis...

Abstract

The invention belongs to the technical field of display and particularly relates to a double-sided display panel and a double-sided display device comprising the double-sided display panel. The double-sided display panel comprises a first display subunit and a second display subunit which are arranged back to each other, and a coloring substrate is further arranged between the first display subunit and the second display subunit and is capable of enabling the first display subunit and the second display subunit to display colors simultaneously. The double-sided display panel has the advantages that preparation technology difficulty and production difficulty of the double-sided display panel are lowered greatly, and cost of the preparation process and the technical process of the double-sided display panel is reduced. Besides, the double-sided display panel has fewer layers so that the double-sided display device is thinned correspondingly. Accordingly, product quality is guaranteed, and the double-sided display panel conforms to the trend that electronic products become thinner and lighter.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a double-sided display panel and a double-sided display device including the double-sided display panel. Background technique [0002] Following the trend of diversification of display functions, double-sided display devices have emerged. Double-sided display has many advantages. For example, when a double-sided display device is used as a TV signal receiving device at home, it can be embedded in the door frame or partition wall of an adjacent room, so that people in different rooms can get the same TV signal at the same time. information or different information. [0003] The double-sided display devices currently produced are usually two single-sided display panels, such as a single-sided liquid crystal (LC) panel and / or OLED (Organic Light-Emitting Diode: organic light-emitting diode) display panel. And formed, some are even formed by using two single-sided disp...
