[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] It is obvious to those skilled in the art that various modifications and changes can be made in the present application without departing from the spirit or scope of the present application. Therefore, the present application is intended to cover modifications and changes of the present application that fall within the scope of the corresponding claims (technical solutions for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present application can be combined with each other without contradiction.

[0040] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] As described in the background technology section, transparent display devices based on technologies such as LED and OLED have great limitations in terms of resolution.

[0042] This is because in transparent display devices based on technologies such as LED and OLED, the light-emitting areas of LED and OLED are non-transparent areas regardless of whether they are in a light-emitting state. As the resolution of the display device increases, the light-emitting areas in the display device will increase, thereby increasing the proportion of non-transparent areas in the display device, thereby reducing the proportion of transparent areas in the display device, affecting the transparent display effect of the display device.

[0043] In view of this, an embodiment of the present application provides a display device, such as Figure 1 and Figure 2 As shown, including:

[0044] A flexible display component 10, wherein the flexible display component 10 comprises at least one layer of an electrochromic structure, wherein the electrochromic structure comprises a plurality of light adjustment regions, and optionally, the electrochromic structure is a flexible transparent film layer;

[0045] A control circuit (not shown in the figure), which provides a control signal to the flexible display assembly 10 to control the light modulation capability of each light modulation area in the electrochromic structure;

[0046] A support base 20 , wherein the support base 20 fixes the flexible display assembly 10 and the control circuit. Optionally, the support base 20 is used to support the flexible display assembly and to store and arrange the control circuit.

[0047] Optionally, in this embodiment, a light adjustment area corresponds to a pixel point of the display device, and a plurality of pixel points located on the same plane constitute a pixel plane, which is distributed on the X-axis and Y-axis in the plane where the display surface of the flexible display component is located. During specific operation, the control circuit adjusts the display effect of the display screen by adjusting the color and depth of each pixel point, and the non-pixel point area remains transparent. It should be noted that a pixel point is the smallest controllable light point on a display device such as an electronic display or a digital camera, and is the basic component element of the smallest unit in the picture. Usually, a pixel point can only display one color or brightness, and its size depends on parameters such as the resolution and size of the screen of the display device.

[0048] In this embodiment, the flexible display component realizes the display of the display image by modulating the external ambient light through the light adjustment areas in the electrochromic structure, so that the light adjustment areas in the display device can realize transparent display when the image is not displayed, so as to make full use of the space in the flexible display component, increase the area of ​​the display device that can be used to realize transparent display, and help improve the resolution of the display device.

[0049] Moreover, in this embodiment, since the flexible display component is a flexible transparent display component, that is, each light adjustment area in the flexible display component can achieve transparent display when not displaying an image, so that the display image of the display device can be integrated with the environment on the non-display side of the display device, providing a more realistic performance effect.

[0050] In addition, in the display device provided in the embodiment of the present application, the flexible display component has the characteristics of being flexible and bendable, and therefore, the display device can be applied to the fields of curved display, wearable devices, etc.

[0051] It should be noted that, in this embodiment, the electrochromic structure includes an electrochromic material. It should be noted that the electrochromic material can realize different colors by applying a voltage, and can also maintain the original state after the voltage is removed, so the electrochromic material can be applied to display. This display device does not require background light, can solve the damage to the reader's eyes caused by the emitted light of the current display device, and can also save energy.

[0052] It should also be noted that, in terms of application, electrochromic display technology can be widely used in electronic equipment, instrumentation, smart home and other fields. For example, the application of electrochromic display technology on a smart phone can adaptively adjust the screen brightness, thereby reducing energy consumption and extending battery life. Therefore, the display device provided in the embodiment of the present application can be a display device in any device with a display function, and the present application does not limit this, depending on the specific circumstances.

[0053] In addition, in the display device provided in the embodiment of the present application, the flexible display component realizes the display of the display screen by modulating the external ambient light through the light adjustment areas in the electrochromic structure, without the need for a light source to generate light, which is beneficial for reducing the thickness of the display device, reducing the cost of the display device, and reducing the energy consumption of the display device.

[0054] In addition, in the embodiment of the present application, the display component in the display device is a flexible display component, so that the display device can be applied to display fields with requirements such as bending and folding, and during the bending or folding process of the display device, different layers in the flexible display component are not easily peeled off.

The first conductive layer 14 and the second conductive layer 15 are used to provide a control voltage to the electrochromic layer 13 to control the light modulation capability of each light modulation area. The first flexible substrate 11 and the second flexible substrate 12 are transparent flexible substrates.

[0056] During specific operation, the first conductive layer and the second conductive layer apply voltage to the electrochromic layer, and the electrochromic material in the electrochromic layer undergoes physical changes, thereby changing the transmission and reflection characteristics of light, so that the control circuit can achieve optical responses of different parts of the electrochromic layer by controlling the voltage on the first conductive layer and the second conductive layer, thereby presenting different display images.
