Description of the invention: [Technical field to which the invention pertains] The present invention relates to a display device. [Prior Art] • Thinner display devices such as LCD display have become increasingly popular and are replacing cathode ray tube displays in various fields. LCD monitors have become the most common form of computer monitors that are supplied with the novel desktop-type electric fines, and of course the #laptop computer. These displays offer significant space savings and portability compared to crt displays. Fortunately, large LCD displays and larger plasma display panels have also become cheaper and have improved performance, making them now competitive with larger CRT displays in the home sector. The door hangs and these displays hang over the wall, eliminating the need for floor space and providing flexibility for optimal positioning. However, larger LCD displays can be considered unsightly, and have been built (eg, by using a semi-transparent mirror on the surface of the LCD to hide the self-visible range when the screen does not provide a round-up . SUMMARY OF THE INVENTION According to the present invention, there is provided a display device comprising: 'a first illuminating display panel; a second bistable display panel provided on the first display portion; It can be operated in the second mode and the second mode. In the -first mode, the second display panel is in a transparent mode to allow viewing from the underside = two 122945.doc 200813913: the display output of the panel 'and in one In the second mode, the second:::: board is in a reflective display mode to provide a reflective display wheel and the display panel is closed. This = therefore provides a display that can act as a normal display or can be used to provide a reflection in a low power bistable mode of operation. In this manner, the device can provide an output such that the display device can present the appearance of a framed picture, although the selected image can be altered to accommodate the room, illumination, and the like. This situation is particularly advantageous for home entertainment, where the mid-rail is not considered to be an eye-catching thing. There are also commercial applications. In an example, the apparatus can be operated in a third mode wherein the first display panel acts as a backlight for the transmissive mode of operation of the second panel. This situation can be provided in a slower, video-like manner (in a transmit rather than a reflective mode) with lower power consumption. Using the first derivative as a back, 曰/f hitting the Chu-two" ^ and making the ❹-panel provided-image can eliminate the power consumption associated with the address period of the display, because the bistable display w(four) μsheng image 'And the first-display (eg '-lcd) operates only as a continuous light source. The device is operable in a four-four mode, wherein the second display panel provides a frame image to complement the output of the first display panel. The two display panels can thus be raised (4) to provide the desired output. In another example, slowly changing image data (such as an on-screen menu) may be displayed by the second display, and the more rapidly changing video material may be displayed by the first display panel. The first display panel preferably includes a color video display panel such as an LCD panel or an electroluminescent display panel.

A display panel 12 The second display panel 14 is bistable' and this means that it has zero power consumption to retain an image. The board 14 operates as a reflective display device when a shadow 2 is displayed. However, 14 also has a transparent mode that allows viewing of images from underlying. Has a slower response time. By independently controlling the two display panels 12, "many modes are operated. <,, the member is not set to 10, a normal video output mode can be accessed, and the first display panel 14 is in a transparent mode. The middle buddy is used to allow viewing from the display output of the lower 1 2 . This mode is schematically illustrated in Figure 2, which shows that the static image output mode can be considered to be a basin. : indicates the _ in-reflection display mode to provide - two = the first display panel 12 (package, bracket, north, ", the staff does not output (including the moonlight 16) is turned off. This mode is schematically illustrated Drag and drop. Image of 122945.doc 200813913. Also shown in Figure 3, the portion of the display area of Figure 2 has been used to provide an image of a picture frame. # These two basic modes of operation enable the display device to act as a The normal display device' is used to provide a reflection in the low-power bistable operation mode. 2. In this way, the device can provide - output, so that the display device can "appear the appearance of the picture", although of course The selected image can be changed Match h main brother, room attire, lighting, etc. This situation is especially beneficial for home entertainment (where the larger display is considered to be an eye-catching thing). In low-power bistable mode, the image is only It needs to be written to the second display panel at one time. The clothing can include the automatic control setting 'Whenever the first display panel is closed, the desired image is reloaded to the second display panel before the device is powered off. The still image 'and even downloaded from the external source into the device. The device is described as having two displays, panels, , but these panels may not be discrete individual components and may be integrated into a single device. The reference to the I-T panel is intended to be functional #, of course, the device of the present invention can be implemented only by physically superimposing and installing two independent panel devices and appropriately controlling them. The display panel 12 can be a conventional LCD panel. However, alternatively, a /, electroluminescent (LED) display device, or a plasma display. In essence, the first display panel can include a supply Any desired illuminating display technology of image quality and frame rate. The first alpha non-panel may comprise an electrophoretic display device. The electrophoretic display device is an example of a bistable display technology, which uses charged particles in an electric field 122945.doc -10· 200813913 Move to provide selective light scattering, subtractive or absorptive functions. It has been recognized that electrophoretic display devices enable low power/short consumption due to their bistable results (an image is retained without voltage applied) And it can enable the formation of thinner display devices, which are not required for backlights or polarizers, but can also be made of plastic materials, and there are also low-cost reel processing in the manufacture of such displays. Possibility. If the cost is kept as low as possible, a passive addressing mechanism is used. The simplest configuration of the display device is a segmented reflective display, and there are many applications in which this type of display is sufficient. The segmented reflectance electrophoretic display device has low power consumption, good brightness, and is also bistable during operation, and thus is capable of displaying information even when the display is turned off. However, the use of matrix addressing mechanisms provides improved performance and versatility. When required - a bright full-color display day temple with a resolution gray scale, an active matrix addressing mechanism is usually required. These devices are being developed for use in signage and billboard display applications, and in (pixel) light sources in electronic windows and ambient lighting applications. The color shirt can be implemented using a color filter and the display pixels can only be used as a gray scale or a subtractive particle (CMYK). This invention is particularly advantageous in that it uses the so-called "coplanar switching." This type of device uses particles to select I* hairy, selective movement in the display material layer. As the particles move toward the lateral electrodes, an opening I is present between the electrodes through which the underlying surface is visible. This situation provides the transmissive mode of operation required for the functionality of the device explained above. On a substrate, or, the two substrates can be equipped with electrodes, and the cost is increased due to the need for alignment. 122945.doc 200813913 Look; when the child is randomly/knife is 'blocking' The light reaches the channel of the underlying surface and the particle color is visible. The particles can be colored and the underlying surface is colored: white, or the particles are black or white: colored. In this implementation, the underlying surface will, for example, contain a closed coffee panel and the h-shape will typically take the form of a black screen. The coplanar switching device can be operated by the Shi ▲ reflection. In detail, in the transmission operation , or transmission subtractive The sub-movement establishing light path reflection and transmissive operation can be implemented via the material. This situation means that the device can also be operated in backlight. The open 1 re-reflection operation thus gives an additional mode of operation, first When used as a backlight for the transmissive mode of operation of the second panel 14. This situation can provide = power consumption using the transmit mode instead of the reflective mode to display an image: ...: the above-mentioned two display panel 14 can have a lower renewed The rate is such that the image is slowly changed. This case provides a lower power side for displaying the image in the illumination mode compared to using only: 22 avoids the power associated with the renewed display of the first display panel 12. Because the first I display panel 12 is only used as the _backlight, the two display outputs can be combined to define the total output image: therefore, the first display panel 12 can be used for the moving part of the image, and the:: Shadow: Static part. For example, the second display defines the shadow of the image displayed by the panel of the younger brother. Alternatively, the second display image has a static portion (such as a menu on the screen), and the content is displayed by the first display handle 12 +, , ι — , and the unloading 1A shoulder. In these examples, the second display panel is driven to the transparent mode in an area that is not used to provide the #% image. As described above, the first display panel 12 may include an electroluminescence display device. This type of functionality can provide all of the functions outlined above, as a full color high speed light emitting display can use this technique to form a 'scratch, which can be made transparent' which provides additional for the device of the present invention. Window mode of operation. In this mode, both displays are set to be transparent, and the device acts as a window with built-in display capabilities. This situation can be beneficial to store facades, offices, shops, vehicles, and the like. Two different types of display panels required to implement the display device of the present invention are readily available for this reason 'the actual display description is not given. A controller is required to synchronize the operation of the two display panels (including the backlight). This controller is shown schematically as 18 in Figure i. Control (4) implementation will be used by those skilled in the art. In the simplest implementation, whenever the first display panel is in use, the second display panel is only driven to the transmissive state, and whenever the first display panel is not in use, the second display panel is driven. To display a still image. The slightly more complex mode of operation described above requires two (four) different parts of the output: synchronized to provide the desired combined effect, but the implementation of this situation is cooked; commonly used by the skilled artisan. For this reason, the controllers required to monitor the operation of the two display panels are not described in detail. The present invention is applicable not only to LCD TV screens and LCD monitors, but also to small screens such as mobile phone screens. In all cases, 杳 122945.doc 200813913 When the screen is closed, the 纟 appearance shows the image selected by the user. The present invention is also applicable to kanban applications, and enables single-label designs to have the ability to display full or bistable static images and maintain the individual benefits of each display mode as desired. Transparent embodiments also enable the use of Windows applications
