Embodiment Construction
[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0029] First of all, it should be noted that one of the reasons for the ripples in the photos or videos captured by the existing flexible display devices using the under-screen camera is the backplane ( figure 1 The material shown is polyethylene terephthalate, the first backplane 2001) has a high birefringence and has a high degree of dispersion to the light entering the camera. In view of this, embodiments of the present invention provide a new display device.

Abstract
An embodiment of the present invention provides a display device, the display device includes: a display panel, including a display area and a binding area, the display area includes a display surface and a non-display surface arranged oppositely, and the binding area includes a binding surface arranged oppositely and a non-binding surface; a first backplane, the first backplane is located on the non-display surface of the display area; a second backplane, the second backplane is located in the non-binding area of the binding area surface; the birefringence of the first backplane is lower than the birefringence of the second backplane. In the embodiment of the present invention, by disposing the first backplane and the second backplane respectively in the display area and the binding area of the display panel, on the one hand, the bendable flexible display panel can be supported and protected; The birefringence of the backplane is lower than the birefringence of the second backplane. Therefore, compared with a display device using the second backplane on the entire surface, the embodiments of the present invention can improve the photos or videos captured by the under-screen camera. the moiré phenomenon, thereby improving the shooting effect.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display device and a manufacturing method thereof. Background technique [0002] At present, the frameless design of the screen of a display device such as an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device has gradually become a popular design trend. A frameless screen refers to a screen with a very narrow frame, which integrates the screen and the frame. At the same time, the frame cannot be seen visually. One of its advantages is its outstanding appearance. Compared with the screen with thick frame in the past, the frameless screen can not only be more fashionable in appearance, but also the display device using the frameless screen. The splicing of display devices can be well realized, so as to achieve better display effect of double screens, triple screens and even multiple screens. In addition, the borderless s...
