Description
本發明涉及一種顯示裝置，特別涉及一種液晶顯示裝置。The present invention relates to a display device, and more particularly to a liquid crystal display device.
目前，各種消費性電子產品如電腦已經走進了千家萬戶。隨著技術的進步，電腦無論功能還是性能上都有很大提高，而作為電腦重要組成部分的顯示器也有了很大改進。目前，由於液晶顯示器（LCD，Liquid Crystal Display）具有輻射低，畫面閃爍小等特點，已經逐漸代替傳統的CRT（cathode-ray tube，陰極射線管）顯示器而成為主流的顯示裝置。At present, various consumer electronic products such as computers have entered thousands of households. With the advancement of technology, the computer has greatly improved its functions and performance, and the display as an important part of the computer has also been greatly improved. At present, liquid crystal displays (LCDs) have become the mainstream display devices by replacing the conventional CRT (cathode-ray tube) displays because of their low radiation and small flickering.
然而，無論CRT顯示器還是液晶顯示器，在同一時刻均只能顯示一個視頻信號所對應的畫面內容，因此，有多少數目的電腦主機，就必須有相應數目的顯示器，這樣當有多台主機而只有一台顯示器時，只能輪流使用該顯示器，無顯示器的用戶因為無法看到操作介面而無法對該電腦主機進行輸入操作。However, regardless of the CRT display or the liquid crystal display, only one video signal corresponding to the video content can be displayed at the same time.

請參閱圖1，為本發明第一實施方式中液晶顯示面板的結構示意圖。該液晶顯示面板10包括一背光單元101、一導光單元102、一液晶陣列單元103。該背光單元101用於為該液晶顯示面板10提供光源，包括分別位於兩端的光源1011，在本實施方式中，該光源1011為一冷陰極管，該背光單元101還包括一反射板1012，用於將該光源1011發出的光進行反射後朝著該導光單元102發射。該導光單元102為一包括多個梯形體1021的玻璃面板。該液晶陣列單元103包括多個呈梯形凹面結構的液晶單元1031，每個液晶單元1031對應於該導光單元102的一梯形體1021，該液晶單元1031包括三個面，該三個面分別與該導光單元102的梯形體1021的三個面平行。1 is a schematic structural view of a liquid crystal display panel according to a first embodiment of the present invention. The liquid crystal display panel 10 includes a backlight unit 101, a light guiding unit 102, and a liquid crystal array unit 103. The backlight unit 101 is configured to provide a light source for the liquid crystal display panel 10, and includes a light source 1011 at each end. In the embodiment, the light source 1011 is a cold cathode tube, and the backlight unit 101 further includes a reflector 1012. After the light emitted from the light source 1011 is reflected, it is emitted toward the light guiding unit 102. The light guiding unit 102 is a glass panel including a plurality of trapezoidal bodies 1021. The liquid crystal array unit 103 includes a plurality of liquid crystal cells 1031 having a trapezoidal concave structure. Each liquid crystal cell 1031 corresponds to a trapezoidal body 1021 of the light guiding unit 102. The liquid crystal cell 1031 includes three faces, and the three faces respectively The three faces of the trapezoidal body 1021 of the light guiding unit 102 are parallel.
請一併參閱圖2，為液晶單元一表面的結構示意圖。設該液晶單元1031的三個面分別為第一表面S1、第二表面S2以及第三表面S3，其中該第一表面S1、第二表面S2以及第三表面S3均包括三個液晶分子以及位於該液晶分子前的紅色、綠色、藍色濾光片R、G、B，該三個液晶分子以RGB陣列排列組成一圖元點。當從該背光單元101發射的光傳輸到該導光單元102時，由於光的折射作用，該背光單元發射的光從該導光單元102的梯形底面射入後，分別從該梯形體1021的三個表面垂直射出。由於該液晶單元1031的三個面分別平行於該導光單元102的梯形體1021的三個面，從而該光線通過該導光單元102後分別發射至該液晶單元1031的三個面，分別為該液晶單元103的三個面提供光源。由於該液晶單元1031的每個面都有三個液晶分子組成的RGB陣列，當該液晶分子旋轉成與該光線平行時，則允許光線通過，從而由於相應的濾光片的作用而顯示相應的顏色，當該液晶分子旋轉成與該光線垂直時，則阻止光線通過，則通過液晶分子的旋轉而顯示不同的顏色。Please refer to FIG. 2 together for a schematic structural view of a surface of the liquid crystal cell. The three surfaces of the liquid crystal cell 1031 are respectively a first surface S1, a second surface S2, and a third surface S3, wherein the first surface S1, the second surface S2, and the third surface S3 each include three liquid crystal molecules and are located The red, green, and blue filters R, G, and B in front of the liquid crystal molecules, and the three liquid crystal molecules are arranged in an RGB array to form a pixel point. 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. Since each surface of the liquid crystal cell 1031 has an RGB array of three liquid crystal molecules, when the liquid crystal molecules are rotated in parallel with the light, the light is allowed to pass, thereby displaying the corresponding color due to the action of the corresponding filter. When the liquid crystal molecules are rotated perpendicular to the light, the light is prevented from passing, and different colors are displayed by the rotation of the liquid crystal molecules.
在本實施方式中，所有液晶單元1031的第一表面S1上的液晶分子組成了第一液晶分子陣列C1，所有液晶單元1031的第二表面S2上的液晶分子組成了第二液晶分子陣列C2，所有液晶單元1031的第三表面S3上的液晶分子組成了第三液晶分子陣列C3。該第一、第二、第三液晶分子陣列C3分別受控於不同的驅動模組（圖中未示）。In the present embodiment, the liquid crystal molecules on the first surface S1 of all the liquid crystal cells 1031 constitute the first liquid crystal molecule array C1, and the liquid crystal molecules on the second surface S2 of all the liquid crystal cells 1031 constitute the second liquid crystal molecule array C2. The liquid crystal molecules on the third surface S3 of all the liquid crystal cells 1031 constitute the third liquid crystal molecule array C3. The first, second, and third liquid crystal molecular arrays C3 are respectively controlled by different driving modules (not shown).
請一併參閱圖3，為液晶顯示面板觀看視角示意圖。如圖所示，由於所有第一表面S1上的液晶分子分別對應一圖元點，則所有第一表面S1上液晶分子所對應的圖元點構成了第一觀看視角顯示面，在本實施方式中，該第一觀看視角顯示面為正面，即從正面觀看所顯示的畫面。由於所有第二表面S2上的液晶分子同樣分別對應一圖元點，則該第二表面S2上的液晶分子對應的圖元點構成了第二觀看視角顯示面，在本實施方式中，該第二觀看視角顯示面為左斜面，即從左斜面觀看所顯示的畫面。同理，由於所有第三表面S3上的液晶分子同樣分別對應一圖元點，則該第三表面S3上的液晶分子對應的圖元點構成了第三觀看視角顯示面，在本實施方式中，該第三觀看視角顯示面為右斜面，即從右斜方觀看所顯示的畫面。在本實施方式中，該液晶單元1031以及該導光單元102中的梯形體的大小均為納米級，因此雖然所有第一表面S1之間、所有第二表面S2之間以及所有第三表面S3之間會有無液晶分子的空隙，但並不會影響該整個第一、第二、第三觀看視角顯示面所顯示畫面的完整性。Please refer to FIG. 3 together for a schematic view of the viewing angle of the liquid crystal display panel. As shown in the figure, since the liquid crystal molecules on all the first surfaces S1 respectively correspond to one pixel point, the pixel points corresponding to the liquid crystal molecules on all the first surfaces S1 constitute a first viewing angle display surface, in this embodiment. The first viewing angle display surface is front side, that is, the displayed picture is viewed from the front. Since the liquid crystal molecules on all the second surfaces S2 also respectively correspond to one pixel point, the pixel points corresponding to the liquid crystal molecules on the second surface S2 constitute a second viewing angle display surface. 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 gaps between the liquid crystal molecules, but it will not affect the integrity of the picture displayed by the entire first, second, and third viewing angle display surfaces.
當不同的驅動模組控制該第一、第二、第三液晶分子陣列C1、C2、C3中液晶分子的旋轉時，可在該第一、第二、第三觀看視角顯示面分別顯示不同的內容。When different driving modules control the rotation of the liquid crystal molecules in the first, second, and third liquid crystal molecular arrays C1, C2, and C3, the first, second, and third viewing angle display surfaces may respectively display different content.
