Description of the Invention: [Technical Field of the Invention] The present invention is a liquid crystal video device and device. In particular, it refers to a kind of liquid crystal video that can be displayed on both sides. [Prior Art] With the digitalized listening «, 啼 _, pM represented by Wei Lai has been widely popularized, the handheld device market is also used as IT f- Important and promising markets are valued by most 1T merchants. The emergence of more and more models in the market has provided consumers with a large selection of space, and at the same time put forward higher and higher requirements for market competition. It is well known that 'the current situation of the handheld device's peach touch _ in the performance of 'on the basis of this, on the basis of its appearance is also a big investment. Small and lightweight, the stylish equipment booth is more _ expensive. The double-fine series of fine-fine I's has attracted many consumers with its unique appearance and unique performance, but the conventional dual-display handheld device has the complexity of the (four) structure compared to the ordinary single. Screen machine, the corresponding cost increase in the thickness increase of the fuselage has also increased, which limits the sales market to a certain extent. Handheld and liquid 曰曰 display (Lcd) mainly has DSTN (dual-scan twisted matic double) Scan the father's wrong liquid crystal display) and (let in (1) 咐 『 、, the thin film transistor does not show the two-sided type 'but the structure of the two _, * To achieve the medullary display, it is necessary to double the structure of 1314657, also There is a corresponding circuit board, and the wire side has space, which increases the volume and increases the cost. [Summary of the Invention] I have a dance. This invention is a new item on the topic. It can be used for double-sided display. To replace the traditional dual-screen handheld dual-LCD structure 'to reduce the screen space and reduce production costs. Therefore, in order to achieve the above object, the present invention provides a liquid crystal display device capable of double-sided display, which is to remove a reflective film of a liquid crystal display having a reflective film to realize double-sided video display of a single LCD, and the device comprises: - a liquid crystal display device, For video display, it comprises a liquid crystal S formed by two upper and lower conductive glass plates H, and the box is full of liquid crystal; a detecting unit, the detecting unit is a rotating shaft angle sensor, which has a two-electrode sliding piece, The two-electrode slider is in an on state or a closed state for detecting a position state of the liquid crystal display device; and a driving control unit is configured to drive the money according to the position state of the liquid crystal display device detected by the detecting unit. The liquid crystal display device is controlled to perform display. The invention is proposed to solve the defect of the double-screen clamshell hand-held design, by simplifying its internal structure, reducing the cost, reducing the thickness of the fuselage, reducing the weight of the fuselage, and making the dual screen Mobile phones have a broader market. The details and the technology of the present invention are described below with reference to the drawings. [Embodiment] 1314657 The present invention is a liquid crystal video device capable of double-sided display 'by simple modification of the existing transmissive liquid crystal display device The sensing device and the corresponding software realize the function of intelligent single-sided LCD double-sided display, that is, the reflective film of the existing LCD is removed, and the LCD becomes a transparent body, so that the displayed image can be seen on both sides of the CD. Since the liquid crystal is a passive light-emitting display, it is necessary to have an external light source for the liquid crystal to be displayed. There are two main types of LCD displays: j) STN (dual-scan twisted nematic) and TFT (thin film transistor). Some parts of different types of liquid crystal display devices may be different. Taking TFT as an example, a finished TFT is not visible, and generally consists of a lost layer. Each layer constituting this interlayer is roughly composed of a polarizing plate' color light-emitting sheet. Between the layers is the liquid crystal layer. What is the difference between the material plate and the color filter?

The two layers guide the liquid crystal display device for display. Wherein, the light source is provided for the liquid crystal display. The two layers of 1314657 electric glass also have an alignment fiim on the side contacting the liquid crystal, so that the liquid crystals are arranged in a predetermined order. Please refer to "Figure 1". This figure is a schematic diagram of the structure of a conventional LCD. Conventional liquid crystal display devices each have a reflective film 12A. After the incident light ray 13 passes through the LCD 110, it is reflected by the reflective film 120 to form reflected light 14 〇 reflected back. The present invention removes the reflective film of the prior art (as shown in Fig. 2) so that the incident light 13〇 can penetrate the LCD 11() directly so that the pattern can be seen in both directions of LQ). The present invention will be described in detail below by taking a dual-screen mobile phone as an example. Please refer to FIG. 3, which is a schematic structural diagram of the mobile phone of the present invention. As shown in the figure, the basic structure of the flip phone includes a body 31〇 and a cover 32〇, and the LCD is embedded in the cover. The body 310 and the cover 320 are reduced by the rotating shaft 330. The LCD cover 520 rotating the shaft 330 is mounted on the cover 320 to make the cover 320 and the body 310 at an angle, thereby opening and closing the camp. The body 3i has a protruding button 34, which is a state sensor, and can sense the state of the cover 320. • See “Figure 4” for details. Off is the wire diagram for the operation of the present invention. The domain first judges the 'on state of the screen (step 41〇). When the user opens the cover, the screen is turned on, and the LCD displays the pattern in the normal state (step 42Q), and the user can view the pattern on the inner side of the cover; The curtain is closed. When the protrusion on the body is pressed by the red 304, the pattern is reversed, and the pattern is displayed in the opposite direction (step 43G), and the user can view the pattern on the outside of the cover. #See Fig. 5' This figure shows the flow axis of the interrupt processing. When the camp 1314657 is opened or closed (step 510), the system first generates an interrupt signal (step 52), enters the interrupt processing program (step 530), and starts checking the state of the sensor (step 54), when the screen When in the normal open state, the f-screen state is set to the on state (step 56Q), that is, the normal state is displayed; when the camp is in the closed state, the screen state is closed (step brush), that is, the pattern is reversed. display. The state sensor can also be an angle sensor. Please refer to FIG. 6 , which is a schematic structural view of the angle sensor of the present invention. In the present embodiment, a switch connected to the rotating shaft is used as the state ❹m, the rotating shaft 33G is divided into the sense region, and the portion is the conductive region 610' and the other portion is the insulating region 62A. When the LCD display screen is closed, the rotating shaft 33 is rotated, and the electrode 1 slider 630 and the electrode 2 slider 640 are in an on state or in a closed state, thereby causing the LCD to generate two non-display states. Since the La) can be displayed on both sides, the user can see the pattern in the LCD regardless of whether the cover is in the open state or the closed state. Although the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and therefore, those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of protection of the present invention is subject to the definition of patent scope in the appended claims.
