Description
本發明係有關於一種顯示裝置及其控制方法，尤指一種利用磁力之顯示裝置及其控制方法。The present invention relates to a display device and a control method thereof, and more particularly to a display device using magnetic force and a control method thereof.
液晶顯示裝置已大量取代陰極射線管顯示裝置。由於液晶顯示裝置無法自行發光，需要利用獨立之光源方能顯示畫面；此外，有機電子發光(OLED)顯示裝置係利用將一電場施加於某一特定有機或聚合物時發生之發光現象，用以代替無法自發光的液晶顯示裝置。Liquid crystal display devices have largely replaced cathode ray tube display devices. Since the liquid crystal display device cannot emit light by itself, it is necessary to use a separate light source to display the image; in addition, the organic electronic light-emitting (OLED) display device utilizes a light-emitting phenomenon that occurs when an electric field is applied to a specific organic or polymer. Instead of a liquid crystal display device that cannot self-illuminate.
但不論是何種顯示裝置，其在使用狀態下均需持續地供應電能，如前述之有機電子發光顯示裝置，其中每一像素皆包含開關電晶體、電容器、驅動電晶體及有機發光二極體；電容器係連接於由外部傳送施加電力之電力線，並且經由資料信號而充電；當驅動電晶體經由該資料信號而開啟，該驅動電晶體傳送電流，在控制電流量之後使電流經過該電力線至有機發光二極體，藉以使有機發光二極體發光，而二極體之發光強度與傳送至有機發光二極體之電流量呈正比。換言之，有機電子發光顯示裝置之像素可經由資料信號之開啟，而該像素之驅動電晶體亦開啟，藉此可持續的將電流施加於有機發光二極體上，以形成顯示影像之效果。However, regardless of the display device, it is required to continuously supply electric energy in the state of use, such as the above-mentioned organic electroluminescent display device, wherein each pixel includes a switching transistor, a capacitor, a driving transistor, and an organic light emitting diode. The capacitor is connected to a power line that transmits power by external transmission, and is charged via a data signal; when the driving transistor is turned on via the data signal, the driving transistor transmits a current, and after controlling the amount of current, the current is passed through the power line to the organic The light emitting diode is configured to cause the organic light emitting diode to emit light, and the luminous intensity of the diode is proportional to the amount of current transmitted to the organic light emitting diode. In other words, the pixels of the organic electroluminescent display device can be turned on via the data signal, and the driving transistor of the pixel is also turned on, thereby continuously applying a current to the organic light emitting diode to form an effect of displaying an image.
又如液晶顯示裝置亦需提供能源至顯示裝置的獨立之光源，例如背光模組，藉由背光模組所發出的光線方可顯示畫面，因此，液晶顯示裝置在使用時同樣必須持續地供應電源，才可以進行畫面的呈現，此即造成高耗電之問題。For example, the liquid crystal display device also needs to provide an independent light source to the display device, such as a backlight module, and the light emitted by the backlight module can display the image. Therefore, the liquid crystal display device must also continuously supply power when used. Only when the picture is presented, this causes a problem of high power consumption.
再者，上述有機電子發光顯示裝置之驅動電晶體在長時間使用下可能出現性能退化的問題，而改變驅動電晶體之臨界電壓，臨界電壓之變化亦造成驅動電晶體之輸出電流的不穩定，以致有機發光二極體之發光均勻性降低，因此造成顯示影像之品質的下降。Furthermore, the driving transistor of the above organic electroluminescent display device may have a problem of performance degradation under long-term use, and changing the threshold voltage of the driving transistor, the variation of the threshold voltage also causes instability of the output current of the driving transistor. As a result, the uniformity of light emission of the organic light-emitting diode is lowered, thereby causing a decrease in the quality of the displayed image.

請參考圖1，本發明所提出之顯示裝置係由顯示單元11及控制單元12所組成，顯示單元11具有多個可轉動之永久磁極性板110，控制單元12具有多個對應於該些永久磁極性板110之可變磁極磁鐵模組12A及一具有導磁特性之磁吸件12B，控制單元12即可用於控制永久磁極性板110的轉向，使永久磁極性板110的某個特定表面朝向顯示單元11之顯示方向X。Referring to FIG. 1 , the display device of the present invention is composed of a display unit 11 and a control unit 12 . The display unit 11 has a plurality of rotatable permanent magnetic polarity plates 110 , and the control unit 12 has a plurality of corresponding permanent portions. The variable pole magnet module 12A of the magnetic polarity plate 110 and a magnetic member 12B having magnetic conductive characteristics, the control unit 12 can be used to control the steering of the permanent magnetic polarity plate 110 to make a certain surface of the permanent magnetic polarity plate 110. The display direction X of the display unit 11 is directed.
具體而言，永久磁極性板110為可轉動地設置於顯示裝置中，例如顯示裝置可包括一框體(圖未示)，而樞接軸13係固定於框體之內部，永久磁極性板110則樞設於樞接軸13，換言之，永久磁極性板110可利用樞接軸13，例如金屬棒、金屬桿或非金屬絲線等為轉軸而進行樞轉。值得說明的是，圖1僅繪製出兩個串設於樞接軸13之永久磁極性板110以進行說明。永久磁極性板110較佳地為永久磁鐵所製成，例如天然的永久磁鐵或是人造的永久磁鐵，如化學式為Nd2 Fe14 B之釹鐵硼磁鐵、釤鈷磁鐵或鐵氧磁鐵等等。再者，每一永久磁極性板110具有相對的一第一色彩面11A及一第二色彩面11B，第一色彩面11A具有第一磁極性，第二色彩面11B則具有第二磁極性；例如在本具體實施例中，永久磁極性板110之S磁極性的一面係為黑色(即第一色彩面11A)，而永久磁極性板110之N磁極性的一面係為白色(即第二色彩面11B)，但不以此為限，上述永久磁極性板110的兩面亦可為其他的顏色，比如紅、綠、茶色，青等，僅需要使永久磁極性板110的兩面具有不同色彩即可。Specifically, the permanent magnetic polarity plate 110 is rotatably disposed in the display device. For example, the display device may include a frame (not shown), and the pivot shaft 13 is fixed inside the frame, and the permanent magnetic polarity plate is 110 is pivotally disposed on the pivot shaft 13, in other words, the permanent magnetic polarity plate 110 can be pivoted by the pivot shaft 13, such as a metal bar, a metal rod or a non-metal wire. It should be noted that FIG. 1 only draws two permanent magnetic polarity plates 110 arranged in series on the pivot shaft 13 for illustration. The permanent magnetic polarity plate 110 is preferably made of a permanent magnet, such as a natural permanent magnet or an artificial permanent magnet, such as a neodymium iron boron magnet of the chemical formula Nd 2 Fe 14 B, a samarium cobalt magnet or a ferrite magnet, and the like. . Furthermore, each permanent magnetic polarity plate 110 has a first color surface 11A and a second color surface 11B, the first color surface 11A has a first magnetic polarity, and the second color surface 11B has a second magnetic polarity; For example, in the present embodiment, one side of the S magnetic polarity of the permanent magnetic polarity plate 110 is black (ie, the first color surface 11A), and one side of the N magnetic polarity of the permanent magnetic polarity plate 110 is white (ie, the second The color surface 11B), but not limited thereto, the two sides of the permanent magnetic polarity plate 110 may be other colors, such as red, green, brown, cyan, etc., and only need to have different colors on both sides of the permanent magnetic polarity plate 110. Just fine.
另外，在一變化實施例中，永久磁極性板110可為轉動地懸浮於一流體中而形成微膠囊的態樣。換言之，微膠囊之內部填充有分散流體，而永久磁極性板110係可控制地懸浮於分散流體中，其製作方法可利用凝聚法，其利用分散劑將在微膠囊之內部所包含的成分(如1~10wt%之增稠劑、抗沈澱劑等)均勻分散而形成分散流體，並使永久磁極性板110懸浮於分散流體中，其中增稠劑可為具有羥基之脂肪酸雙醯胺，分散劑可使用水、乙二醇類等極性分散劑或有機類、油類等非極性溶劑；亦即本發明並不限制永久磁極性板110的形式與態樣，其僅需具備可轉動的特性，以被控制單元12之可變磁極磁鐵模組12A所驅動而轉動其方向即可，較佳地，永久磁極性板110旋轉之軸心係大致垂直於顯示方向X。Additionally, in a variant embodiment, the permanent magnetic polarity plate 110 can be rotatably suspended in a fluid to form a microcapsule. In other words, the inside of the microcapsule is filled with a dispersion fluid, and the permanent magnetic polarity plate 110 is controllably suspended in the dispersion fluid, and the preparation method thereof can utilize a coacervation method in which the component contained in the inside of the microcapsule is utilized by the dispersant ( Such as 1~10wt% thickener, anti-precipitant, etc.) uniformly dispersed to form a dispersion fluid, and the permanent magnetic polar plate 110 is suspended in the dispersion fluid, wherein the thickener may be a fatty acid bis-amine having a hydroxyl group, dispersed The agent may use a polar dispersant such as water or ethylene glycol or a non-polar solvent such as an organic or oil; that is, the present invention does not limit the form and the form of the permanent magnetic polar plate 110, and only needs to have a rotatable property. It is sufficient that the variable magnetic pole magnet module 12A of the control unit 12 is driven to rotate its direction. Preferably, the axis of rotation of the permanent magnetic polarity plate 110 is substantially perpendicular to the display direction X.
控制單元12之可變磁極磁鐵模組12A係為一種可受控制而改變其磁極性的模組。具體而言，可變磁極磁鐵模組12A可為鐵芯121及繞設於鐵芯121上之線圈122所組成之電磁鐵模組，控制單元12更可包括一電性連接於可變磁極磁鐵模組12A的控制模組(圖未示)，控制模組可控制輸入可變磁極磁鐵模組12A的電流方向、大小等參數，當直流電通過線圈122時會產生類似棒狀磁鐵的磁場，使在線圈122的中心之鐵芯121被磁化而達到加強磁場的效果。The variable magnetic pole magnet module 12A of the control unit 12 is a module that can be controlled to change its magnetic polarity. Specifically, the variable magnetic pole magnet module 12A can be an electromagnet module composed of a core 121 and a coil 122 disposed on the core 121. The control unit 12 can further include an electrical connection to the variable pole magnet. The control module (not shown) of the module 12A controls the current direction and size of the input variable magnetic pole magnet module 12A. When the direct current passes through the coil 122, a magnetic field similar to a rod magnet is generated. The core 121 at the center of the coil 122 is magnetized to achieve the effect of reinforcing the magnetic field.
控制單元12之磁吸件12B係為一種可受磁力、磁場作用而產生磁化效果之材料所製成，例如磁吸件12B可為鐵、鈷、鎳其混合物等材質所製成的板件，其面積大約等同於顯示單元11的整體面積，更具體地說，磁吸件12B可為矽鋼板、純鐵板、坡莫合金板等等，其本身並不具有磁場，但可受到外來磁場而激發出相對應的磁極，而產生相互吸引的效果；但磁吸件12B亦可具有磁性，但其磁性不影響可變磁極磁鐵模組12A控制永久磁極性板110為佳。另外，前述之可變磁極磁鐵模組12A與磁吸件12B可利用各種組裝方式固定於框體之中。The magnetic material 12B of the control unit 12 is made of a material that can be magnetized by a magnetic field or a magnetic field. For example, the magnetic material 12B can be a plate made of a mixture of iron, cobalt, nickel, or the like. The area is approximately equal to the overall area of the display unit 11, and more specifically, the magnetic member 12B may be a samarium steel plate, a pure iron plate, a permalloy plate or the like, which does not have a magnetic field itself, but may be subjected to an external magnetic field. The magnetic poles are excited to generate mutual attraction effects; however, the magnetic material 12B may also have magnetic properties, but the magnetic properties thereof do not affect the variable magnetic pole magnet module 12A to control the permanent magnetic polarity plate 110. Further, the variable magnetic pole magnet module 12A and the magnetic member 12B described above can be fixed to the housing by various assembling methods.
值得說明的是，如圖2A所示，顯示單元11、該可變磁極磁鐵模組12A與磁吸件12B係在相反於該顯示方向X的方向上依序排列，換言之，觀賞者可在顯示方向X的方向上看到顯示單元11之永久磁極性板110的色彩顯示及排列等效果。It should be noted that, as shown in FIG. 2A, the display unit 11, the variable magnetic pole magnet module 12A and the magnetic member 12B are sequentially arranged in a direction opposite to the display direction X, in other words, the viewer can display The color display and arrangement of the permanent magnetic polarity plate 110 of the display unit 11 are seen in the direction of the direction X.
請配合圖3，本發明之顯示裝置的控制方法可至少包括以下步驟：S101：提供一顯示裝置，如前文所述，本發明之顯示裝置主要由顯示單元11及控制單元12所組成，而顯示單元11及控制單元12的具體實施態樣可參考前文，在此不予贅述。With reference to FIG. 3, the control method of the display device of the present invention may include at least the following steps: S101: providing a display device. As described above, the display device of the present invention is mainly composed of the display unit 11 and the control unit 12, and is displayed. For specific implementations of the unit 11 and the control unit 12, reference may be made to the foregoing, and details are not described herein.
S103：提供電流改變可變磁極磁鐵模組12A的磁極性，調整每一可變磁極磁鐵模組12A所對應之永久磁極性板110的該第一色彩面11A與該第二色彩面11B的其中之一朝向顯示裝置的一顯示方向X。具體而言，在本步驟中係改變可變磁極磁鐵模組12A的磁極性，藉以控制永久磁極性板110朝向顯示方向X的色彩面。S103: The magnetic polarity of the variable magnetic pole magnet module 12A is changed, and the first color surface 11A and the second color surface 11B of the permanent magnetic polarity plate 110 corresponding to each variable magnetic pole magnet module 12A are adjusted. One of them faces a display direction X of the display device. Specifically, in this step, the magnetic polarity of the variable magnetic pole magnet module 12A is changed, thereby controlling the color plane of the permanent magnetic polarity plate 110 toward the display direction X.
請參考圖1A，其顯示兩組可變磁極磁鐵模組12A與永久磁極性板110的控制態樣；如圖所示，本實施例可利用控制模組(圖未示)控制輸入可變磁極磁鐵模組12A的電流方向、大小等參數，使圖面上方的可變磁極磁鐵模組12A呈現左端為N磁極性，右端為S磁極性的磁場態樣，而圖面下方的可變磁極磁鐵模組12A則呈現左端為S磁極性，右端為N磁極性的磁場態樣；換言之，本步驟係利用控制模組控制輸入可變磁極磁鐵模組12A的電流，使可變磁極磁鐵模組12A呈現出S磁極性及N磁極性的其中之一。Please refer to FIG. 1A, which shows the control modes of the two sets of variable magnetic pole magnet modules 12A and the permanent magnetic polarity plates 110. As shown in the figure, the control module (not shown) can be used to control the input variable magnetic poles. The current direction, size and other parameters of the magnet module 12A are such that the variable magnetic pole magnet module 12A above the drawing surface has a magnetic polarity of the left end with an N magnetic polarity and a right end with a S magnetic polarity, and the variable magnetic pole magnet below the drawing surface. The module 12A has a magnetic field state in which the left end is S magnetic polarity and the right end is N magnetic polarity; in other words, this step controls the current input to the variable magnetic pole magnet module 12A by using the control module, so that the variable magnetic pole magnet module 12A One of the S magnetic polarity and the N magnetic polarity is exhibited.
而當可變磁極磁鐵模組12A的磁場態樣出現變化時，即可利用磁力之同性相斥、異性相吸的原理以磁性連動的方式調整永久磁極性板110的方向，如圖所示，圖面上方的可變磁極磁鐵模組12A之右端(即接近永久磁極性板110的一端)為S磁極性，故圖面上方的永久磁極性板110會沿著樞接軸13進行轉動，使N磁極性的第二色彩面11B被可變磁極磁鐵模組12A所吸引，藉以將圖面上方的永久磁極性板110之S磁極性的第一色彩面11A朝向顯示方向X。同理，圖面下方的可變磁極磁鐵模組12A之右端(即接近永久磁極性板110的一端)為N磁極性，故圖面下方的永久磁極性板110之S磁極性的第一色彩面11A則被可變磁極磁鐵模組12A所吸引，藉以將圖面上方的永久磁極性板110之N磁極性的第二色彩面11B朝向顯示方向X。藉此，觀賞者即可觀察到兩種不同的色彩面。When the magnetic field state of the variable magnetic pole magnet module 12A changes, the direction of the permanent magnetic polarity plate 110 can be adjusted in a magnetic linkage manner by using the principle of magnetic homogeneity and opposite phase attraction, as shown in the figure. The right end of the variable magnetic pole magnet module 12A above the drawing surface (ie, the end close to the permanent magnetic polarity plate 110) is S magnetic polarity, so the permanent magnetic polarity plate 110 above the drawing surface rotates along the pivot axis 13 The second color surface 11B of the N magnetic polarity is attracted by the variable magnetic pole magnet module 12A, whereby the first color surface 11A of the S magnetic polarity of the permanent magnetic polarity plate 110 above the drawing faces the display direction X. Similarly, the right end of the variable magnetic pole magnet module 12A below the drawing surface (ie, the end close to the permanent magnetic polarity plate 110) is N magnetic polarity, so the first color of the S magnetic polarity of the permanent magnetic polarity plate 110 below the drawing surface is the same. The surface 11A is attracted by the variable magnetic pole magnet module 12A, whereby the second color surface 11B of the N magnetic polarity of the permanent magnetic polarity plate 110 above the drawing faces the display direction X. In this way, the viewer can observe two different color surfaces.
接著，S105：切斷電流使可變磁極磁鐵模組12A不具磁性，此時，調整後之每一永久磁極性板110係吸附於該磁吸件12B而使該第一色彩面11A與該第二色彩面11B的其中之一固定地朝向該顯示方向X。在此步驟中，由於每一永久磁極性板110已被其所對應之可變磁極磁鐵模組12A控制而將特定的色彩面朝向該顯示方向X，而當控制模組切斷輸入可變磁極磁鐵模組12A的電流，可變磁極磁鐵模組12A即不再具有磁性，而已經呈現出圖樣之永久磁極性板110則會因磁力而吸附於磁吸件12B，進以使永久磁極性板110仍固定地保持其所呈現的圖樣。更具體地說，可變磁極磁鐵模組12A主要係用於控制、切換永久磁極性板110所呈現的色彩與圖樣，而當可變磁極磁鐵模組12A之電流切斷後，永久磁極性板110可被磁吸件12B所吸引而固定其位置。請參考圖2、圖2A，本具體實施例係以黑白兩色進行圖樣的呈現，如前文所述，永久磁極性板110之第一色彩面11A係為黑色，而第二色彩面11B係為白色，而觀賞者可觀察到一個大致呈現出笑臉圖樣(如圖2)或數字8(如圖2A)的顯示態樣，請注意圖2、圖2A之顯示方向X係為射出紙面的方向。Next, S105: cutting off the current so that the variable magnetic pole magnet module 12A is not magnetic. At this time, each of the adjusted permanent magnetic polar plates 110 is adsorbed to the magnetic member 12B to make the first color surface 11A and the first One of the two color faces 11B is fixedly oriented toward the display direction X. In this step, since each permanent magnetic polarity plate 110 has been controlled by its corresponding variable magnetic pole magnet module 12A to face a specific color plane toward the display direction X, when the control module cuts off the input variable magnetic pole The current of the magnet module 12A, the variable pole magnet module 12A is no longer magnetic, and the permanent magnetic polarity plate 110 that has been patterned is adsorbed to the magnetic member 12B by magnetic force, so that the permanent magnetic polarity plate is advanced. 110 still maintains the pattern it presents. More specifically, the variable magnetic pole magnet module 12A is mainly used for controlling and switching the color and pattern presented by the permanent magnetic polarity plate 110. When the current of the variable magnetic pole magnet module 12A is cut off, the permanent magnetic polarity plate 110 is used. It can be attracted by the magnetic member 12B to fix its position. Referring to FIG. 2 and FIG. 2A, the present embodiment presents the pattern in black and white. As described above, the first color surface 11A of the permanent magnetic polarity plate 110 is black, and the second color surface 11B is White, and the viewer can observe a display aspect that roughly presents a smiley pattern (as shown in Figure 2) or a number 8 (as shown in Figure 2A). Please note that the display direction X of Figure 2 and Figure 2A is the direction in which the paper is ejected.
而當本發明之顯示裝置欲顯示下一章畫面時，即可重複進行步驟S103，使永久磁極性板110因可變磁極磁鐵模組12A的磁場變化而對應地使第一色彩面11A或第二色彩面11B朝向顯示方向X；接著，關閉可變磁極磁鐵模組12A的磁場，使永久磁極性板110因本身與磁吸件12B之間的磁力吸附而固定其所呈現的圖樣或畫面。When the display device of the present invention is to display the next chapter screen, step S103 may be repeated to make the permanent magnetic polarity plate 110 correspondingly change the magnetic field of the variable magnetic pole magnet module 12A to correspondingly make the first color surface 11A or the first The two color surface 11B faces the display direction X. Next, the magnetic field of the variable magnetic pole magnet module 12A is closed, and the permanent magnetic polarity plate 110 is fixed by the magnetic force between itself and the magnetic member 12B to fix the pattern or screen presented.
值得說明的是，本發明並不限制於上述的僅能呈現黑白的灰階顯示裝置，例如可將四個永久磁極性板110組合成一組顯示陣列，其上分別具有CMYK的不同色彩面，並搭配人眼辨識度而將永久磁極性板110的尺寸微小化，即可讓人眼觀察到256階或以上的彩色畫面。It should be noted that the present invention is not limited to the above-described gray scale display device capable of only displaying black and white. For example, four permanent magnetic polarity plates 110 may be combined into a set of display arrays having CMYK different color planes thereon, and By minimizing the size of the permanent magnetic polarity plate 110 in accordance with the degree of human eye recognition, it is possible to visually observe a color picture of 256 steps or more.
因此，本發明係提出一種以磁力控制的顯示裝置，其可利用可變磁極磁鐵模組12A的磁場變化而調整出所欲顯示的圖樣、色彩或畫面，且永久磁極性板110之顯示態樣已確定後，更可將可變磁極磁鐵模組12A的磁場關閉，並藉由永久磁極性板110與磁吸件12B之間的磁吸附力而保持永久磁極性板110的顯示態樣，故亦達到減少能源耗損的效果。Therefore, the present invention provides a magnetically controlled display device that can adjust the pattern, color or picture to be displayed by the magnetic field change of the variable magnetic pole magnet module 12A, and the display pattern of the permanent magnetic polarity plate 110 has been After the determination, the magnetic field of the variable magnetic pole magnet module 12A can be turned off, and the display state of the permanent magnetic polarity plate 110 is maintained by the magnetic attraction force between the permanent magnetic polarity plate 110 and the magnetic member 12B.
