Description

[0001] The present invention relates to a video display device having a multi-layer display device,

The present invention is characterized in that a display device 1 including an electronic ink display device on one side of a fixed body and two kinds of display devices having different characteristics such as a transparent display device including a transparent OLED panel and a transparent LCD are mounted on one surface of a fixed body Layer display device that is stacked and performs a selective display function by a control unit. The image display device is electrically connected to the control unit to selectively intercept light from the display device 1 and light outflow from the display device 1, An optical shutter that performs a function of transmitting light is applied.

When the smartphone is turned off or inactive, the screen of all smartphones is black regardless of the manufacturer and the user.

OLED-enabled smart phones also maintain a black screen when turned off or inactive, and many transparent OLED-related patents have been proposed unlike conventional OLEDs that are opaque (Korea Patent: 10-2010-0117340 , 10-2015-0123118)

It is also possible to consider an image display device which replaces an opaque OLED with a transparent OLED only. In this case, in the off state or in a deactivated state, the adhesion state with the front surface of the fixed body is exposed, There is a problem that an image identification problem in which only the on-screen display image is displayed and the front supporting surfaces of the fixed body are overlapped can be caused.

Also, a so-called " Yoda phone ", in which an electronic ink display device is applied as a separate second display device on the back side opposite to the screen display surface of the smartphone, has been introduced and an electronic ink display device is applied as a separate second display device Patents have been proposed (Korean Patent Application No. 10-2016-0012369).

Since the above-mentioned " Yoda phone " is applied as an additional display device to the back side opposite to the screen display surface to which the OLED display device or the LCD display device is applied, the electronic ink is displayed only when the back side of the smart phone is exposed to the user When the OLED display device or the LCD display device is turned off or in an inactive state, a black screen that does not provide any information to the user is maintained through the OLED display device or the LCD display device Disadvantages are maintained.

In addition, in the case of "Yodafone", there is a problem that additional touch-related components and protective glass or protective film must be applied to the electronic ink for protecting the screen to which the electronic ink is applied and for applying the touch operation function, .

In the case of applying a patent to which electronic ink is applied as a separate second display device to a smartphone case, opaque electronic ink is applied on the display screen of the OLED display device or the LCD display device, It is inconvenient to turn the OLED display device or the LCD display device into the exposed state by rotating or sliding the case to which the electronic ink is applied in order to use the display through the case, and in the same way as in the case of the " Yoda phone " In order to apply the screen protection function and the touch operation function, there arises a cost increase problem in which an additional touch operation related component and a protective glass or a protective film are applied on the electronic ink of the case.

A patent for solving the problem of a black screen in a power off or in a deactivated state of the image display apparatus to which the opaque LCD and the opaque OLED are applied is filed by the present inventor (Korean Patent Application No. 10-2017-0099397).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The terminology used herein is for the purpose of illustrating embodiments and is not intended to be limiting of the present invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. In addition, reference signs presented in the order of description are not necessarily limited to the order.

1 is a conceptual diagram, a cross-sectional view, and a partial detail view of a screen display off state and a screen display on state of a conventional smartphone or tablet image display apparatus.

In FIG. 1, the polarizer plates are omitted. As shown in FIG. 1, in the case of a conventional smartphone or tablet, an LCD is applied between linear polarizer plates having different polarization angles. As a result, power of a smartphone or a tablet Is turned off or inactive after being turned on, it remains black, which does not give any useful information to the user, and can be released from the state only after the smartphone or tablet is turned on and then turned on.

The black state of the image display device, which is kept off or in an inactive state, causes the user to be unable to confirm important information that should be always known for a certain period of time from the image display device, After activating, you should run an app such as Notepad to check the information or use a case that can apply supplementary means such as Post-it.

In order to solve such a problem, a patent (Korean Patent Application No. 10-2017-0099397) is filed by the inventor of the present invention, and FIG. 2 shows a patent (Korean Patent Application No. 10-2017-0099397) A top view, a cross-sectional view, and a partial detail view as part of the drawings of FIG.
