Description

透明顯示器transparent display

本創作係有關於一種透明顯示器，尤其是關於一種利用單層透明基板同時兼具基板與保護層作用的透明顯示器，具有節省材料的優點。This creation is related to a transparent display, especially a transparent display that utilizes a single-layer transparent substrate to simultaneously function as a substrate and a protective layer, which has the advantage of saving materials.

隨著顯示技術的進步，除了一般的顯示器之外，業界也開始研發將發光元件製作於透明的基板(例如玻璃)上的顯示器，又可稱為透明顯示器，其同時具有透光以及顯示器的功能。當發光元件不啟動時，可以當作普通的透光玻璃使用，而當發光元件啟動時，則能在透明的玻璃上產生圖案，以顯示例如商標或是廣告等。With the advancement of display technology, in addition to general displays, the industry has also begun to develop displays in which light-emitting elements are fabricated on transparent substrates (such as glass), also known as transparent displays, which have both light transmission and display functions. . When the light-emitting element is not activated, it can be used as an ordinary light-transmitting glass, and when the light-emitting element is activated, a pattern can be produced on the transparent glass to display trademarks or advertisements, for example.

第1圖繪示一種現有的透明顯示器的剖面結構圖，如第1圖所示，積體控制電路11作為控制器連接發光元件10(例如發光二極體)，兩者之間藉由多條導線12相連。其中上述元件位於一不透明載板14(例如為印刷電路板)上，然後不透明載板14位於一透明基板16(例如玻璃)上。此外，還包含有另一保護板18(例如另一片透明玻璃)覆蓋於上述發光元件10以及不透明載板14上方，用於保護上述元件。上述結構中，增加發光元件10的數量時，不透明載板14的面積也會隨之變大以容納更多個發光元件10。但不透明載板14的面積增大，由於透明基板16(例如玻璃或窗戶)的面積不變，將會導致透明基板16的透光面積變少，進而影響到總透光率(也就是透明基板可透光的面積/透明基板的總面積)。除此之外，上述結構必須要包含有保護板18用於保護較為脆弱的發光元件10，如此也增加了成本。FIG. 1 shows a cross-sectional structure diagram of a conventional transparent display. As shown in FIG. 1, the integrated control circuit 11 is used as a controller to connect the light-emitting element 10 (such as a light-emitting diode), and a plurality of LEDs are connected between the two. Wires 12 are connected. The above-mentioned components are located on an opaque carrier 14 (eg, a printed circuit board), and then the opaque carrier 14 is located on a transparent substrate 16 (eg, glass). In addition, another protective plate 18 (eg, another piece of transparent glass) is also included to cover the above-mentioned light-emitting element 10 and the opaque carrier plate 14 for protecting the above-mentioned elements. In the above structure, when the number of light-emitting elements 10 is increased, the area of the opaque carrier plate 14 will also increase accordingly to accommodate more light-emitting elements 10 . However, the area of the opaque carrier plate 14 increases. Since the area of the transparent substrate 16 (such as glass or window) remains unchanged, the light transmission area of the transparent substrate 16 will decrease, thereby affecting the total light transmittance (that is, the transparent substrate). area that can transmit light/total area of transparent substrate). Besides, the above structure must include a protection plate 18 to protect the relatively fragile light-emitting element 10, which also increases the cost.

因此，需要一種新的結構，在提高透明顯示器的發光效率的同時，也能維持良好的透光率並且降低製作成本。Therefore, there is a need for a new structure that can maintain good light transmittance and reduce manufacturing costs while improving the luminous efficiency of the transparent display.

As shown in FIG. 2 , an integrated control circuit 20 is provided first. The integrated control circuit 20 has two surfaces, which are respectively defined as a first surface 20A and an opposite second surface 20B. It should be noted that the internal structure of the integrated control circuit 20 in this embodiment is substantially similar to the conventional integrated control circuit, including many logic elements such as switching elements, which can be used as a controller. However, in this embodiment, the pins of the IC 20 are not located on both sides as in the conventional IC, but are located on one of the surfaces of the IC 20 , the first surface 20A is taken as an example. That is, by design, the pins of the integrated control circuit 20 are extended on the first surface 20A, leaving a plurality of conductive electrodes 22A and 22B on the first surface 20A for connecting to other electronic components (eg, used to connect light-emitting elements, etc.). The electrodes 22A and 22B mentioned here both belong to the electrodes on the integrated control circuit 20 , but since the components connected subsequently are different, they are distinguished by different component numbers.

接著，在積體控制電路20上形成發光元件24以及焊接元件26，其中發光元件24以及焊接元件26均位於積體控制電路20上的第一表面20A，且其中發光元件24電性連接電極22A，而焊接結構26電性連接電極22B。也就是說，與習知技術不同的是，本創作中發光元件24以及焊接元件26位於積體控制電路20同一側的表面上，並且分別連接不同的電極。其中焊接元件26例如為表面黏著元件(Surface mount device，SMD)，用於連接後續提供的透明基板。而本創作的發光元件24則例如是發光二極體，或進一步包含有機發光二極體(organic light emitting diode，OLED)、次毫米發光二極體(mini LED)、微發光二極體(micro LED)或量子點發光二極體(quantum dot LED)，但不以此為限。其中發光元件24可發出單色或是多色混合光，例如紅光、藍光、綠光或是其他由多種顏色的組合的混合光(白光等)，本創作並不以此為限。Next, the light-emitting element 24 and the soldering element 26 are formed on the integrated control circuit 20, wherein the light-emitting element 24 and the soldering element 26 are both located on the first surface 20A of the integrated control circuit 20, and the light-emitting element 24 is electrically connected to the electrode 22A , and the welding structure 26 is electrically connected to the electrode 22B. That is to say, different from the prior art, in the present invention, the light-emitting element 24 and the soldering element 26 are located on the same surface of the integrated control circuit 20, and are respectively connected to different electrodes. The soldering element 26 is, for example, a surface mount device (SMD), which is used to connect the transparent substrate provided subsequently. The light-emitting element 24 of the present invention is, for example, a light-emitting diode, or further includes an organic light-emitting diode (OLED), a sub-millimeter light-emitting diode (mini LED), and a micro light-emitting diode (micro light-emitting diode). LED) or quantum dot light-emitting diode (quantum dot LED), but not limited thereto.

The transparent substrate 30 is, for example, glass, such as the transparent glass used to produce a light-emitting display effect on a window, but the present invention is not limited to this.

The transparent wire 32 is electrically connected to the above-mentioned welding element 26, and a power source (not shown in the figure) can be provided externally. Electric power is supplied to the light-emitting element 24 to emit light. It is worth noting that the light L emitted by the light-emitting element 24 in this embodiment penetrates through the transparent substrate 30 and can be observed by the user, that is, the transparent substrate 30 in this embodiment not only has the integrated control circuit 20 . In addition to the functions of other elements (eg, the light-emitting element 24 ), it can also be used as a protective plate. Therefore, only one layer of the transparent substrate 30 is required to have both the substrate and the protective plate in the prior art, and it is not necessary to separately manufacture the substrate and the protective plate, which can reduce the manufacturing cost, and can effectively improve the manufacturing process because the manufacturing process steps are also reduced. efficiency.
