When the light emitted from the backlight unit 101 is transmitted to the light guiding unit 102, the light emitted by the backlight unit is incident from the trapezoidal bottom surface of the light guiding unit 102, respectively, from the trapezoidal body 1021 due to the refraction of light. The three surfaces are shot perpendicularly. Since the three faces of the liquid crystal cell 1031 are respectively parallel to the three faces of the trapezoidal body 1021 of the light guiding unit 102, the light passes through the light guiding unit 102 and is respectively emitted to the three faces of the liquid crystal cell 1031, respectively The three faces of the liquid crystal cell 103 provide a light source.

In this embodiment, the first The viewing angle of the viewing view is the left bevel, that is, the displayed image is viewed from the left bevel. Similarly, since all the liquid crystal molecules on the third surface S3 also correspond to one pixel point, the pixel points corresponding to the liquid crystal molecules on the third surface S3 constitute a third viewing angle display surface, in this embodiment. The third viewing angle display surface is a right slope, that is, the displayed image is viewed from the right oblique side. In the present embodiment, the sizes of the liquid crystal cell 1031 and the trapezoidal body in the light guiding unit 102 are all on the order of nanometers, so although all the first surfaces S1, all the second surfaces S2, and all the third surfaces S3 There will be no voids between the liquid crystal molecules, but it will not affect the integrity of the kneading surface displayed by the entire first, second, and third viewing angle display surfaces.

The control signals of the third signal modules 20, 30, and 40, and respectively control the rotation of the liquid crystal molecules in the first, second, and third liquid crystal molecular arrays C1, C2, and C3. [0017] When the first display interface D1 is connected to the first computer host and receives the video signal of the first computer host, the video signal received through the first display interface!) is transmitted to the first signal. a conversion module 2, the first signal conversion module 20 receives the video signal and converts the video signal into a control signal. The first driving module 5 controls the liquid crystal in the first liquid crystal molecular array C1 according to the control signal. The rotation of the molecules, so that the first viewing angle display surface of the liquid crystal display panel 20, that is, the image corresponding to the video signal is displayed on the front side. When the second display interface D2 is connected to a second computer host to receive a video signal, the video signal received through the second display interface D2 is transmitted to the second signal conversion module 30, and the second signal conversion module 3 098130857 Form No. A0101 Page 10 of 22 0982052956-0 201109789 ❹ [0018] After receiving the video signal, the video signal is converted into a control signal, and the second driving module 60 controls the second liquid crystal according to the control signal The rotation of the liquid crystal molecules in the molecular array C2 causes the second viewing angle display surface of the liquid crystal display panel 10 to display an image corresponding to the display signal. When the third display interface D3 is connected to a third computer host to receive the video signal, the video signal received through the third display interface D3 is transmitted to the third signal conversion module 40, and the third signal conversion module 40 receives the video signal. The video signal is converted into a control signal, and the third driving module 70 controls the rotation of the liquid crystal molecules in the third liquid crystal molecular array C 3 according to the control signal, so that the third viewing angle of the liquid crystal display panel 10 is displayed. The image corresponding to the display signal is displayed on the right side. The first, second, and third driving modules 50, 60, and 70 are specifically driving electrodes, and the control manner of the liquid crystal molecular array is the same as that in the prior art, and thus will not be further described herein. The first, second, and third display interfaces D1, D2, and D3 may be a VGA (Video Graphics Array) interface, a DVI (Digital ta 1 Visua 1 Interface), or a USB (Universal Ser) The ia 1 Bus, the universal serial bus interface, the first, second, and third display interfaces D1, D2, and D3 may be located at any position of the liquid crystal display. [0019] In another embodiment, the liquid crystal display 1 may not include the first signal conversion module 20, the second signal conversion module 30, and the third signal conversion module 40, but only includes a processing unit. The unit performs the functions of the first signal conversion module 20, the second signal conversion module 30, and the third signal conversion module 40 in a time-sharing manner. That is, the processing unit is connected to the first display interface D1, the second display interface D2, and the third display interface D3, respectively, for the first display, and the first display interface D1, the second display interface D2, and the third display interface D3 are respectively connected to the 098130857 form number A0101 page/total page 220982052956-0 201109789. The video signals received by the interface D1, the second display interface D2, and the third display interface D3 are converted into control signals, and sequentially transmitted to the first, second, and third driving modules 50, 60, 70. [0020] The liquid crystal display 1 can be connected to three different computer mainframes and respectively display different images at different viewing angles, and can respectively receive video signals of the three computer mainframes on the front side and the left side of the liquid crystal display panel 10, and The different display images corresponding to the video signal are respectively displayed on the right side.
