Description

COMBINED STACKABLE MULTIPLE-DISPLAY Technical Field
The present invention relates to a combined stackable multiple-display which combines different display technologies such as LCD (Liquid-crystal Display) and e-paper (electronic paper).
Background of the Invention
Today, display technologies have also entered into the process of continuous change and development because of advancing technology and electronic devices increasing in number each passing day and responding the need of different requirements today.
Display technologies sometimes stand out because of their performance shown in subjects such as colour quality, resolution and they sometimes are preferred due to power consumption at very low levels. In the state of the art, however, it is required to buy devices wherein each display technology is used separately in order to use these advantages provided by different display technologies. Particularly, a multiple-display solution wherein display technologies combining both high quality image and advantage of power consumption at very low levels within the same structure cannot be achieved today.
Today, LCD display technology gives high performance in terms of resolution and colour and also provides great advantages in terms of power consumption in images that do not change often by means of e-paper technology which is also known as e-ink (electronic ink) because an image can be maintained on the display without needing to send any electric signal to the display until next change after an image is created in displays having e-paper technology. Besides, transparent LCD display technology in the state of the art offers an advantage and plenty of opportunity in terms of transparency in addition to features provided by normal LCD displays.
Using these two different display technologies together may be able to provide a solution of enabling a high-quality image and very low power consumption when necessary.
The Chinese patent document no. CN202217116, an application in the state of the art, discloses an electronic colour-changing panel device which is obtained through an electrophoresis principle. The said device comprises a back panel, an electronic ink layer and a transparent electric conducting layer from the bottom to the top.
The Korean patent document no. KR20090110174, another application in the state of the art, discloses a display device and a method thereof which are provided to reduce the power consumption of a hybrid display device.
The International patent document no. WO2012044201, a further application in the state of the art, discloses a display device comprising front and back major faces wherein the front major face presents a first display screen and the back major face presents a second display screen different to the first display screen.
Summary of the Invention
An objective of the present invention is to realize a combined stackable multiple- display wherein a screen having a transparent LCD display and a display with e- paper technology under thereof is used. Detailed Description of the Invention
The "combined stackable multiple-display" realized to fulfil the objectives of the present invention is shown in the figure attached, in which:
Figure 1 is a representation of the inventive combined stackable multiple- display layers.
The components illustrated in the figure are individually numbered, where the numbers refer to the following:
1. Combined stackable multiple-display
2. E-paper display
3. Transparent LCD display
4. Glass bottom layer
5. Protective cover
The combined stackable multiple-display (1) comprises:
at least one e-paper display (2) which has very low power consumption in images that do not change often and which will display images such as clock, date, wallpaper;
at least one transparent LCD display (3) which is positioned on the e- paper display (2) and configured such that it will not prevent being able to see the e-paper display (2) when it is switched off; - at least one glass bottom layer (4) which is positioned on the transparent LCD display (3) and comprises driving and sensing lines for touch-display function;
at least one glass protective cover (5) which is positioned on the glass bottom layer (4) (Figure 1). The e-paper display (2) is a display which consumes very low energy in images that do not change often and which will display images such as clock, date, wallpaper, read page that will not change often. The transparent LCD display (3) is a display which is positioned on the e-paper display (2) whereas under the glass bottom layer (4), exhibits transparent characteristics when it is switched off; therefore, it is configured such that it will not prevent being able to see the e-paper display (2) when it is switched off. The transparent LCD display (3) is a display which is used for images change often and/or has high resolution and high colour quality.
The glass bottom layer (4) is a layer which is positioned on the transparent LCD display (3) and comprises driving and sensing lines for touch-display function.
The glass protective cover (5) is a layer which is positioned on the glass bottom layer (4) and configured such that it will not prevent being able to see the transparent LCD display (3) and the e-paper display (2). The glass protective cover (5) can be made of a transparent plastic in one embodiment of the invention whereas it can be made of a glass material resistant to scratch and crack in another embodiment of the invention.
The e-paper display (2) and the transparent LCD display (3) can be controlled by the same GPU (Graphical Processing Unit) in one embodiment of the invention whereas they are configured such that they can controlled by different GPU's in a different embodiment of the invention. A processor controlling operating status of GPU's can be used in use of two different GPU's.
With the inventive combined stackable multiple-display (1), it is enabled to use the e-paper display (2) for displaying images that do not change often, display the e-paper display (2) easily by the advantages provided via transparency of the transparent LCD display (3) to be switched off in displaying images that do not change often, thus provide power save. With the inventive combined stackable multiple-display (1), it is enabled to use the transparent LCD display (3) for displaying images that change often and require high resolution and colour quality, thus no compromises is made on image quality. In an exemplary embodiment, the inventive combined stackable multiple-display (1) will use the e-paper display (2) for displaying images such as clock, date, wallpaper, e-book page on a smart phone display when it is used in a smart phone display and the transparent LCD display (3) will be used when it is required to display a webpage, a video, a high resolution picture on a smart phone display. Thereby, it will be ensured to provide power save and high image quality when needed. In addition, the combined stackable multiple-display (1) can also be used as a touch-screen display due to the glass bottom layer (4) comprising driving and sensing lines. In an exemplary embodiment, when it is used on a TV display, the inventive combined stackable multiple-display (1) will ensure displaying a fixed image, for example a table, on the e-paper display (2) while TV is switched off whereas it will be continued to display the image on the transparent LCD display (3) in a V is switched on.
It is possible to develop a great variety of embodiments of the inventive combined stackable multiple-display (1); it cannot be limited to the examples disclosed herein and it is essentially according to the claims.
