    Portable liquid crystal display device with flexible liquid crystal display device
    BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a portable liquid crystal display device having a flexible liquid crystal display device, and more particularly to a liquid crystal display device in which a size of a screen size is increased by being collapsible with a flexible liquid crystal display device.
    A liquid crystal display is a display that displays a desired image using a liquid crystal capable of electrically controlling light transmittance while a light source is secured. A digital wrist watch and a pager can be manufactured with low voltage driving, low power consumption, and thin and light. In recent years, various researches have been conducted to realize light and thin components of electronic devices, such as ultra high density of digital integrated circuits, high capacity of batteries, and thin display.
    In particular, in the portable device, as described above, the light and simple aspect is further emphasized, and the display using the CRT is replaced by a flat panel display such as LCD or EL, but the thickness of the product is also applied to the flat panel display. Can be reduced, but the panel area of the display can not reduce the overall product area, making the user's portability uncomfortable.
    In order to alleviate this inconvenience, conventionally, as disclosed in Korean Patent Application No. 96-41375, a flat panel display having a structure that allows the middle part to be folded and the seam of the folded part is not visible has been proposed. Proposed Korean Patent Application No. 97-58554 provided a flat panel display in which a liquid crystal display device can be divided into a border.
    The present invention provides an improved technology for reducing the mobile size and increasing the screen size of a product applied in the flat panel display described above, and providing a liquid crystal display device in which a compact structure and a seam are removed by integrating the main body and the display by sliding. Purpose.
    In order to achieve the above object, the liquid crystal display device of the present invention is provided with a reinforcement plate which is divided on the back side of a flexible liquid crystal display device including a driving driver, a plurality of circuit boards and a liquid crystal cell, and a plastic film on the outside of the reinforcement plate. In addition, the circuit boards are connected to each other by a flexible circuit board so that the liquid crystal display device can be folded in at least two stages.
    In particular, the main body and the liquid crystal display device may be slidably coupled.

    Explanation of symbols on the main parts of the drawings
    2: body 8: display
    10: slide groove 12: guide support
    14 support shaft 16: frame
    30: flexible circuit board
    Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    1 shows a liquid crystal display device related to the present invention.
    In the drawings, reference numeral 2 denotes a main body. One side of the main body 2 is characterized by being rounded, the upper portion exposed is possible to install the keyboard 4 or the display using the liquid crystal, in the description of the present invention will be described using the keyboard 4 as an example do. The liquid crystal display device is coupled to the main body so as to be slidably accommodated, a display 8 described later attached with a digitizer 6 shown by a dotted line in the figure.
    In order to enable this, guide guides 12 having slide grooves 10 are formed on opposite side surfaces of the main body 2, and support shafts 14 are formed at the lower edges of the display 8. By being inserted into the slide groove 10 can be implemented a screen size that is further enlarged.
    In addition, a frame 16 having a length corresponding to the guide support 12 may be closely installed at an opposite edge portion of the display 8 to prevent distortion of the display 8 during sliding storage or to be easily accommodated. Do it.
    In particular, the slits 18 are placed below the guide support 12 on the upper surface of the main body 2 as shown in FIG. 2 because the display 8 must be electrically connected to the data signal devices stored in the main body 2. It forms and ends one end of the connector 20 integrated therein and connects it with the display 8 side.
    3 and 4, the display 8 includes a liquid crystal cell 24 injecting a liquid crystal between the flexible substrates 22 arranged in parallel, whereby the circuit board 25 is tab mounted. The drive driver 26 is connected to the circuit board 25 by the tab IC 28 to drive the liquid crystal.
    In more detail, the circuit board 25 connected to the liquid crystal cell 24 is connected to a flexible printed circuit board 30 (hereinafter referred to as FPC), which is a kind of connector, to exchange data with each other. Even if the curve is bent, data can be moved without loss.
    The display 8 may be bent in the middle portion of the curved portion 32, but is bent in a round shape corresponding to one side of the main body (2). To this end, a reinforcing plate 34, which is a rigid panel that forms an exterior of the flexible substrate 22 of the curved portion 32, is disposed, and they are divided to form the space portion 36, and again to the outside of the flexible film ( 38) so that it bends smoothly and maintains its shape. In particular, at least two curved portions 32 may be provided in the display, and for this purpose, the reinforcing plate 34, the flexible film 38, and the FPC 30 are formed at portions corresponding to the curved portions 32.
    5A to 5D illustrate the operation of a liquid crystal display device having a flexible liquid crystal display device according to the present invention having such a structure.
    5A shows a state when using the liquid crystal display device according to the present invention, which is a state in which the frame part, which is not shown, of the display 8 is slid into the aforementioned guide support 12 and faced. In this case, since the keyboard 4 of the main body 2 is not exposed, data is input using the digitizer 6 capable of pen input.
    On the other hand, when using the keyboard 4, as shown in Figure 5b, by pulling the display 8, the support shaft 14 is moved in the slide groove 10 so that the frame 16 in the guide support 12 Removing the part allows the keyboard 4 to be exposed.
    Subsequently, the used liquid crystal display device rotates 90 degrees while bending the display 8 to bend the display portion 8 as shown in FIG. 5C, and the support shaft 14 slides the slide groove 10 of the guide support 16. The display 8 is faced to the main body 2 by an orbital rotation at an inner end of the.
    At this time, according to the characteristics of the present invention adopts the FPC connecting the drive driver to the bent portion of the display, the rigid panel is divided into the outside of the flexible substrate is installed and at the same time it is possible to bend the display flexibly with a flexible film.
    As described above, the LCD according to the present invention takes a more improved form.
    That is, the support shaft is formed on the display, the guide support with the slide groove formed on the main body can be formed and slidable, and it can be bent without a seam on the image portion of the display, thereby increasing the screen size and making the display compact. Get the device.
