目前市場上主流的面板顯示技術，可分成液晶顯示(LCD)和發光二極體(LED)兩大類。隨著製程技術的不斷進步，發光二極體的尺寸逐漸從毫米等級邁向了微米等級。尺寸在50~100μm(微米)之間的發光二極體，被稱為次毫米發光二極體。尺寸在30μm以下的發光二極體，則稱為微發光二極體。由次毫米發光二極體或微發光二極體構成的顯示器架構，一般稱為微型顯示器架構。
The mainstream panel display technologies in the current market can be divided into two categories: liquid crystal display (LCD) and light-emitting diode (LED). With the continuous advancement of process technology, the size of LEDs has gradually moved from the millimeter level to the micrometer level. LEDs with a size between 50 and 100μm (micrometers) are called sub-millimeter LEDs. LEDs with a size below 30μm are called micro-LEDs. The display architecture composed of sub-millimeter LEDs or micro-LEDs is generally called a micro-display architecture.

FIG3 shows another conventional micro-display structure 10' applied to a smart keyboard. FIG4 shows a cross-sectional view of the middle plane line BB' of FIG3. Compared with the micro-display structure 10 of FIG1, the micro-display structure 10' of FIG3 also has a plurality of screens 11, 12, 13 and 14 and a plurality of driving integrated circuits 15, 16, 17 and 18. The difference is that the micro display structure 10' of FIG3 has a plurality of driver integrated circuits 15, 16, 17 and 18 disposed on the back of a plurality of screens 11, 12, 13 and 14, respectively, and the plurality of driver integrated circuits 15, 16, 17 and 18 are connected to microcontrollers 23, 24, 25 and 26 through a plurality of flexible printed circuit boards 19', 20', 21' and 22', respectively. FIG4 shows a cross-sectional view of the circuit composed of the screen 13, the driver integrated circuit 17 and the microcontroller 25 in FIG3, and the cross-sectional views of the circuit composed of the remaining screens 11, 12 and 14, the driver integrated circuits 15, 16 and 18 and the microcontrollers 23, 24 and 26 can be inferred from FIG4. As shown in FIG4 , the multiple sub-millimeter light-emitting diodes or micro-light-emitting diodes 131 of the screen 13 are arranged on the upper surface of the circuit board 132, and the driving integrated circuit 17 is arranged on the back side of the circuit board 132 relative to the multiple sub-millimeter light-emitting diodes or micro-light-emitting diodes 131. The driving integrated circuit 17 is connected to the multiple sub-millimeter light-emitting diodes or micro-light-emitting diodes 131 through the metal wires of the circuit board 132. The microcontroller 25 controls the driving integrated circuit 17 to drive the multiple screens 13 through the flexible printed circuit board 21'.
在圖1及圖3中，多個屏幕11、12、13及14分別對應智慧鍵盤上的多個按鍵(圖中未示)。使用者可以透過屏幕11、12、13及14所顯示的文字或圖像知道屏幕11、12、13及14所對應的按鍵的功能。例如，多個驅動積體電路15、16、17及18可以控制多個屏幕11、12、13及14分別顯示文字「A」、「B」、「C」及「D」，使用者可以按壓屏幕11、12、13或14以使智慧鍵盤輸入對應的文字「A」、「B」、「C」或「D」。
In FIG. 1 and FIG. 3, multiple screens 11, 12, 13, and 14 correspond to multiple keys on the smart keyboard (not shown in the figure). The user can know the functions of the keys corresponding to the screens 11, 12, 13, and 14 through the text or images displayed on the screens 11, 12, 13, and 14. For example, multiple driver integrated circuits 15, 16, 17, and 18 can control the multiple screens 11, 12, 13, and 14 to display the text "A", "B", "C", and "D", respectively, and the user can press the screen 11, 12, 13, or 14 to make the smart keyboard input the corresponding text "A", "B", "C", or "D".
然而，在智慧鍵盤中，每一個屏幕11、12、13及14只對應一個按鍵，而且每一個屏幕11、12、13及14都需要一顆獨立的驅動積體電路15、16、17及18來驅動，因此，當智慧鍵盤上的按鍵數越多時，所需要的驅動積體電路也越多，導致成本提高。
However, in the smart keyboard, each screen 11, 12, 13 and 14 corresponds to only one key, and each screen 11, 12, 13 and 14 requires an independent driving integrated circuit 15, 16, 17 and 18 to drive. Therefore, when the number of keys on the smart keyboard is more, more driving integrated circuits are required, resulting in higher costs.

從圖8可知，軟性印刷電路板34、35、36、37、42、43、52及53的多條走線341、351、361、371、421、431、521及531的數量是對應於屏幕31、32、41及51的解析度。以圖8的屏幕31為例，屏幕31的解析度為3×3，即屏幕31的水平方向解析度及垂直方向解析度皆為3，因此在水平方向上連接屏幕31的軟性印刷電路板34及52的多條走線341及351的數量為3，在垂直方向上連接屏幕31的軟性印刷電路板36的多條走線361的數量為3。隨著屏幕31的解析度不同，軟性印刷電路板34、36及52的走線數量也會不同。例如當屏幕31的解析度為1024×768時(即屏幕31的水平方向解析度為1024，而垂直方向解析度為768)，軟性印刷電路板34及52的多條走線341及351的數量將為1024，而軟性印刷電路板36的多條走線361的數量將為768。由於軟性印刷電路板34、35、36、37、42、43、52及53的多條走線341、351、361、371、421、431、521及531的數量是對應於屏幕31、32、41及51的解析度，因此軟性印刷電路板34、35、36、37、42、
43、52及53上的信號都可以直接驅動屏幕31、32、41及51，無需再透過解碼器對軟性印刷電路板34、35、36、37、42、43、52及53上的信號解碼。換言之，屏幕31、32、41及51無需設置積體電路(IC)來進行解碼，因而可以省略積體電路，進而降低成本。
As can be seen from FIG8 , the number of multiple traces 341, 351, 361, 371, 421, 431, 521, and 531 of the flexible printed circuit boards 34, 35, 36, 37, 42, 43, 52, and 53 corresponds to the resolution of the screens 31, 32, 41, and 51. Taking the screen 31 of FIG8 as an example, the resolution of the screen 31 is 3×3, that is, the horizontal resolution and the vertical resolution of the screen 31 are both 3, so the number of multiple traces 341 and 351 connecting the flexible printed circuit boards 34 and 52 of the screen 31 in the horizontal direction is 3, and the number of multiple traces 361 connecting the flexible printed circuit board 36 of the screen 31 in the vertical direction is 3. As the resolution of the screen 31 is different, the number of traces of the flexible printed circuit boards 34, 36, and 52 will also be different. For example, when the resolution of the screen 31 is 1024×768 (i.e., the horizontal resolution of the screen 31 is 1024, and the vertical resolution is 768), the number of the multiple traces 341 and 351 of the flexible printed circuit boards 34 and 52 will be 1024, and the number of the multiple traces 361 of the flexible printed circuit board 36 will be 768. Since the number of multiple traces 341, 351, 361, 371, 421, 431, 521 and 531 of the flexible printed circuit boards 34, 35, 36, 37, 42, 43, 52 and 53 corresponds to the resolution of the screens 31, 32, 41 and 51, the signals on the flexible printed circuit boards 34, 35, 36, 37, 42, 43, 52 and 53 can directly drive the screens 31, 32, 41 and 51, and there is no need to decode the signals on the flexible printed circuit boards 34, 35, 36, 37, 42, 43, 52 and 53 through a decoder. In other words, the screens 31, 32, 41 and 51 do not need to be equipped with an integrated circuit (IC) for decoding, so the integrated circuit can be omitted, thereby reducing costs.

本發明的微型顯示器架構30、40、50、60、70及80只需要一個驅動積體電路33及73即可驅動多個屏幕，因此本發明的微型顯示器架構能夠大大
的降低成本。以圖1的傳統微型顯示器架構10以及圖7的本發明微型顯示器架構50為例，傳統微型顯示器架構10與本發明微型顯示器架構50皆使用四個屏幕，但本發明微型顯示器架構50只需要一個驅動積體電路33來驅動四個屏幕，因此相較於傳統的微型顯示器架構10，本發明微型顯示器架構50的成本約可降低20~30%。
The micro-display architecture 30, 40, 50, 60, 70 and 80 of the present invention only need one driving integrated circuit 33 and 73 to drive multiple screens, so the micro-display architecture of the present invention can greatly reduce the cost. Taking the traditional micro-display architecture 10 of FIG. 1 and the micro-display architecture 50 of the present invention of FIG. 7 as examples, the traditional micro-display architecture 10 and the micro-display architecture 50 of the present invention both use four screens, but the micro-display architecture 50 of the present invention only needs one driving integrated circuit 33 to drive four screens, so compared with the traditional micro-display architecture 10, the cost of the micro-display architecture 50 of the present invention can be reduced by about 20~30%.
