Description of the new type: [Technical field to which the new type belongs] This creation relates to a liquid crystal display device. [Previous technology] — At present, due to the advantages of low power consumption, light weight, short thickness, and low voltage driving of liquid crystal display devices, liquid crystal display devices have been widely used in display screens of mobile communication products such as handheld computers and mobile phones. However, with the advancement of the times, many products need to display images on the front and back of the display screen. To achieve the double-sided display function of the liquid crystal display device, two liquid crystal display modules are required, that is, two single-sided display sub-modules are juxtaposed together, one inward and one outward to realize front and back double-sided display. A prior art double-sided liquid crystal display device. As shown in the first figure, the double-sided liquid crystal display device 10 includes a double-sided light-emitting light guide plate 11, a light guide plate 12 provided on the light guide surface, a light source 13 and two light guide plates, respectively. The liquid crystal display panel groups 14 and 15 on the light emitting surfaces 16 and 17 sides. The light emitted from the light source 13 is incident on the light guide plate u through the light incident surface 12, is separated from the light guide plate 11, and exits from the two light emitting surfaces 16 and 17, and finally enters the two liquid crystal display modules 14 and 15. One two-sided liquid crystal display device 10 uses two liquid crystal display modules 14, 15 and two electronic driving devices must be used to drive the two liquid crystal display modules 14, 15. This structural cost consumes a lot of energy, and leads are complicated, which reduces reliability. At the same time, the use of two liquid crystal display modules increases the thickness of the product, which does not meet the trend of thin, light and short products. In view of this, it is necessary to provide a double-sided liquid crystal display device which is thin and light, has low energy consumption and high reliability. [New content] The purpose of this creation is to provide a double-sided liquid crystal display device that is thin, light, energy-saving, and highly reliable. For the purpose described, this creation provides a double-sided liquid crystal display device, which includes a first trial I, a light source disposed on the side of the light guide plate, and a transmissive and transflective liquid crystal display disposed under the light guide plate. Module. 6 M272110 Compared with the prior art, due to the creation of the double-sided liquid, L, r- A ______ night and day ..., you can use one to achieve a semi-integrated light into the light guide plate from the light guide From the liquid crystal display ^ "also called / from the daily display device, the light is incident on the liquid crystal display module through the liquid crystal through the semi-reflective liquid crystal display module, the light emitted from the light source or the natural display module. The light is transmitted through the liquid crystal display module, and the image seen from the second display panel is a positive image. From this light guide, 'Stupid Two: The image is inverted left and right to achieve double display. The image is used only for the liquid crystal display device. _ Liquid crystal display module = LCD display module's double-sided liquid crystal display device f. This double-sided liquid crystal display device is only used with-liquid crystal display module, and ~ 14¾ driver The connection of the device leads reduces the complexity and guilt of the circuit. At the same time, it can make this creative double-sided liquid crystal display device thinner and thinner. [Embodiment] Please refer to the first figure for this creative double-sided liquid crystal display device The plan view of the first embodiment.

The double-sided liquid crystal display device 20 is used In the semi-transmissive liquid crystal display panel 23, light or natural light emitted from the light source 22 is incident into the semi-transmissive liquid crystal display panel 23. Part of the light penetrates the liquid crystal display panel 23 and exits, and part of the light passes through the liquid crystal. After the display panel 23 is reflected, it enters the light guide plate 21 and exits from the light guide plate 21. The image viewed from the liquid crystal display panel 23 is a positive image, and the image viewed from the light guide plate 21 is a positive image. This positive image is inverted left and right to achieve double-sided display. The original double-sided liquid crystal display device 20 can realize the double-sided display function using only one liquid crystal display panel 23, and the double-sided liquid crystal display using the two liquid crystal display panels of the prior art Compared with the display device, the cost and power consumption are reduced. The original double-sided liquid crystal display device 20 uses only one liquid crystal display panel 23, which reduces the connection with the leads of the electronic driving device, reduces the complexity of the circuit, and increases the complexity. At the same time, the double-sided liquid crystal display device 20 can be made thinner and thinner. Please refer to the third figure, which is an exploded perspective view of the second embodiment of the double-sided liquid crystal display device. The difference between the two-sided liquid crystal display device 20M272110 in one embodiment is that a reflective film 35 with a display window 34 is also provided above the light guide plate 31. The area of the display® port 34 can be adjusted as needed to reach the main and auxiliary sides. The effect of the display screen area varies. The reflective film 35 can reflect a part of the light emitted from the upper surface of the light guide plate 31 and reuse it to improve the utilization of light and display brightness. Please refer to the fourth figure for the text Create a perspective view of the light guide plate of the third embodiment of the double-sided liquid crystal display device.

Because the light directed to the non-display window area of the reflective film is reflected back, and the light in the 44 area of the display window is directly emitted, there may be a shadow in the 44 area of the display window visually. The upper surface 46 of the light guide plate 41 has dots 47, 48, and the above-mentioned shadows can be prevented by the reflection and scattering of the dots 47, 48. Please refer to the fifth figure, which is a perspective view of a light guide plate of the fourth embodiment of the original double-sided liquid crystal display device. The difference between the double-sided liquid crystal display device and the double-sided liquid crystal display device 30 according to the second embodiment is that the upper surface 56 of the light guide plate 51 has dots 57, and the density of the dots 57 relative to the upper surface 56 of the display window 54 is greater than its surroundings. Dot 58 density. Please refer to the sixth figure, which is a perspective view of the light guide plate of the fifth embodiment of the original double-sided liquid crystal display device. The difference between the double-sided liquid crystal display device and the double-sided liquid crystal display device 30 of the second embodiment is that the lower surface 66 of the light guide plate 61 has V-shaped grooves 67 and 68, which are 66V-shaped grooves with respect to the lower surface of the display window 64. The depth of the groove 67 is greater than the depth of the v-shaped grooves 68 around it. The V-shaped grooves 67 and 68 can function as dots and prevent shadows. Please refer to the seventh figure 'is a perspective view of the light guide plate of the sixth embodiment of the original double-sided liquid crystal display device.
