Double-sided display panel and double-sided display device

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...

Problems solved by technology

like figure 2 As shown, the Chinese patent with the authorized announcement number CN202330951U discloses a double-sided display device formed by bonding two independent single-sided display devices, which uses two layers of colored substrates (the first colored substrate 10, the second colored substrate Two colored substrates 11), and two common electrode layers (the first common electrode layer 12, the second common electrode layer 13, generally ITO transparent electrode layer) as the inner layer, and then one layer is pasted on the outer side of the inner layer PDLC layer (first polymer dispersed liquid crystal layer 14, second polymer dispersed liquid crystal layer 15), and then set corresponding array substrates (first array substrate 16, second array substrate 17) to form a double-sided display device. Although the double-sided display device has eliminated the shortcomings of the conventional double-sided liquid crystal display device and double-sided OLED display device to a certain extent, because it is still formed by a simple lamination method, the manufacturing process is relatively complicated, and the gap between the layers It needs to be glued and fixed, and the flatness and alignment of each layer will affect the display effect

At the same time, from the perspective of the image forming mechanism, since the structures of the display devices on both sides are independent and have no common parts, it is not a double-sided display device in the true sense.
