Description

Transparent display scheme using controllable color changing device

Technical Field

The invention relates to the technical field of transparent display, in particular to a transparent display scheme using a controllable color-changing device.

Background

Research has shown that visual information accounts for 60% of information obtained from the outside by various human sense organs, and display technology is popular in earnest because it delivers visual information to users. Display technology has replaced printing technology and has been the main way for knowledge and information transmission for over 100 years.

With the emergence and development of self-luminous display technologies such as OLED and Micro-LED, transparent display technologies are gradually entering the public field of vision and are expected. The transparent display technology has wide application prospect, can be used for show window display, outdoor advertising boards and flat panel display, and even can be used as a glass window, thereby having scientific and unreal feeling. The attention of the related products released in the current market also represents the great interest of the public in the transparent display technology.

The existing transparent display schemes mainly include ambient light backlight type, self-luminous type, projection type and the like, but the problems of insufficient display brightness, poor content expression, content coverage by a background and the like which influence user experience are caused by the fact that the contrast ratio of background content and display content cannot be controlled.

Disclosure of Invention

To solve the above problems, the present invention provides a transparent display scheme using a controllable color changing device.

The invention adopts the following technical scheme:

a transparent display scheme using a controllable color changing device is used to achieve control over the contrast of background content to display content.

Wherein:

the controllable color changing device can control one or more optical properties (e.g., transparency, chromaticity, diffuse reflectance, etc.) of each display region.

A transparent display scheme using a controllable color-changing device, which is used for realizing the control of the contrast ratio of background content and display content, comprises the following specific steps:

for self-emissive transparent display systems: the transparency of each display area is controlled by the controllable color-changing device to limit the passing rate of background light, so that the aim of controlling the contrast ratio of background content and display content is fulfilled.

For a projection-type transparent display system: the transparency of each display area is controlled by the controllable color-changing device to limit the passing rate of the background light, and the diffuse reflection rate of each display area is controlled by the controllable color-changing device to control the diffuse reflection intensity of the projection light, so that the aim of controlling the contrast ratio of the background content and the display content is fulfilled.

The invention has the beneficial effects that: compared with the existing transparent display scheme, the scheme realizes the control of the contrast ratio of the background content and the display content by using the controllable color changing device, and solves the problems of insufficient display brightness, poor content expression, content coverage by the background and the like in the existing transparent display scheme. Simultaneously, this scheme still has application cost low, the technological threshold is low, advantage such as production and processing technology is mature.

Detailed Description

The present invention will be described in further detail with reference to fig. 1.

A transparent display scheme using a controllable color changing device, when used in a self-emissive transparent display system:

when only the single-sided display effect needs to be realized, the self-luminous display device is arranged on one side of the controllable color changing device (such as the position relation of 1 and 3 in fig. 1), and if the double-sided display effect needs to be realized, the self-luminous display device is arranged on two sides of the controllable color changing device (such as the position relation of 1, 2 and 3 in fig. 1). When the transparent display system is in operation, the controllable color changing device is controlled to reduce the transparency of the display content area (such as 4 area in fig. 1) to block the light from passing through (such as 6 and 7 in fig. 1), and to increase the transparency of the background content area (such as the area beyond 4 on 3 in fig. 1) to allow the light to pass through (such as 5 in fig. 1); it is also possible to increase the diffuse reflectance of the display content area (e.g., 4 in fig. 1) to increase the diffuse reflectance intensity of the projection light, and decrease the diffuse reflectance of the background content area (e.g., other than 4 on 3 in fig. 1) to decrease the diffuse reflectance intensity of the projection light.

The invention is described in further detail below with reference to fig. 2.

A transparent display scheme using a controllable color changing device, when used in a projection transparent display system:

the controllable color changing device is used as a light screen. When the transparent display system is in operation, the controllable color changing device is controlled to decrease the transparency of the display content area (e.g., area 2 in fig. 2) to block light from passing (e.g., 4 and 5 in fig. 2), and to increase the transparency of the background content area (e.g., area other than area 1 and area 2 in fig. 2) to allow light to pass (e.g., area 3 in fig. 2).

The present invention is described in further detail below with reference to fig. 3.

A transparent display scheme using a controllable color-changing device is used for realizing the control of the contrast ratio of background content and display content, and the specific control method comprises the following steps:

controlling the controllable color-changing device to improve the transparency of a non-display content area (shown as 2 in fig. 3) on the display surface, reduce the transparency of a display content area (shown as 3 in fig. 3) on the display surface, and adjust the transparency of a corresponding area to an appropriate value if the display content is semitransparent while the display system displays images; if the scheme is used for a projection type transparent display system, the diffuse reflectance of a display content-free area (shown as 2 in fig. 3) on the display surface can be reduced, the diffuse reflectance of a display content area (shown as 3 in fig. 3) on the display surface can be improved, and if the scheme is used for the projection type transparent display system, the diffuse reflectance of the corresponding area is adjusted to an appropriate value.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be considered as the protection scope of the present invention.
