以下將以圖式揭露本發明之複數個實施例，為明確說明起見，許多實務上的細節將在以下敘述中一併說明。然而，應瞭解到，這些實務上的細節不應用以限制本發明。也就是說，在本發明實施例中，這些實務上的細節是非必要的。此外，為簡化圖式起見，一些習知慣用的結構與元件在圖式中將以簡單示意的方式繪示之。Hereinafter, a plurality of embodiments of the present invention will be disclosed in the form of drawings. For clear description, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is to say, in the embodiment of the present invention, these practical details are unnecessary. In addition, in order to simplify the drawings, some conventionally used structures and elements are shown in the drawings in a simple and schematic manner.

將被理解的是，雖然文中使用特定的詞彙，如「第一」、「第二」等用以描述不同元件、空間、或區，但是這些元件、空間、或區並不應限於這些詞彙。這些詞彙用以將一個元件、空間、或區與另一個元件、空間、或區區別。如此，下文敘述的一第一元件、空間、或區可被稱為一第二元件、空間、或區，而不脫離本發明的精神及範疇。It will be understood that although specific words such as "first", "second", etc. are used in the text to describe different elements, spaces, or areas, these elements, spaces, or areas should not be limited to these words. These terms are used to distinguish one element, space, or region from another element, space, or region. In this way, a first element, space, or area described below can be referred to as a second element, space, or area without departing from the spirit and scope of the present invention.

空間的相對詞彙，例如文中使用的「在…內」、「在…之間」、「在…的左右」、「在…上」、等，是為了容易描述圖中所繪示的一元件或特徵與另一元件或特徵之間的關係。由此可理解，除了圖中所描繪的方位外，空間的相對詞彙意指囊括該裝置使用時或操作時的不同方位。舉例來說，假如圖中的裝置被翻轉，則被描寫為「在」其他元件或特徵「上」的元件將被定向為「在」其他元件或特徵「下」。因此，這些示範的詞彙「在…上」可包含上面和下面的方位。裝置可被另外定方位(例如被旋轉90度或在其他的方位)，並且文中使用的空間相對詞彙應相應地被詮釋。The relative terms of space, such as "in", "between", "on the left and right of", "on", etc. used in the text, are used to easily describe an element shown in the figure or The relationship between a feature and another element or feature. It can be understood that, in addition to the orientation depicted in the figure, the relative vocabulary of space means to encompass the different orientations of the device when it is used or operated. For example, if the device in the figure is turned over, elements described as "above" other elements or features will be oriented "below" other elements or features. Therefore, these exemplary words "on" can include directions above and below. The device can be oriented separately (for example, rotated by 90 degrees or in another orientation), and the spatial relative vocabulary used in the text should be interpreted accordingly.

由此可理解，當一元件被稱為在另一元件「上」，或「連接」另一元件時，它可以是直接在另一元件上、或連結另一元件，或可存在一或更多的中間元件或中間層。另外，由此可理解，當一元件被稱為在二元件「之間」時，它可以是該二元件之間唯一的元件或層，或也可存在一或更多的中間元件或中間層。It can be understood from this that when an element is referred to as being "on" or "connected" to another element, it can be directly on or connected to another element, or one or more elements may be present. Many intermediate elements or intermediate layers. In addition, it can be understood from this that when an element is referred to as being "between" two elements, it can be the only element or layer between the two elements, or one or more intermediate elements or intermediate layers may also be present. .

文中使用的術語只是為了描寫特定實施例的目的，並不是用以限制本發明。文中使用的單數形式「一」和「該」也包括複數形式，除非上下文另有清楚的指示。由此更可理解當說明書中使用這些詞「包括」等詞彙時，是明確地說明指定的特徵、整體、步驟、操作、元件及/或構件的存在，但是不排除一或更多的特徵、整體、步驟、操作、元件、構件及/及/或其群組的存在或附加。文中使用的「及/或」包括一或更多相關已列詞彙的任何以及全部組合。當元件列表前面加上，例如「…的至少一個」的修辭，是修飾整個元件列表，而非修飾該表列的個別元件。The terms used in the text are only for the purpose of describing specific embodiments, and are not used to limit the present invention. The singular forms "一" and "the" used in the text also include the plural forms, unless the context clearly indicates otherwise. Therefore, it is more understandable that when these words "include" and other words are used in the specification, they clearly describe the existence of specified features, wholes, steps, operations, elements and/or components, but do not exclude one or more features, The existence or addition of wholes, steps, operations, elements, components and/and/or groups thereof. The term "and/or" used in the text includes any and all combinations of one or more related listed words. When the element list is preceded by rhetoric such as "at least one of", it modifies the entire element list, not the individual elements in the list.

Please refer to FIG. 4, the signal receiving and displaying system 106 of FIG. 1 may further include a piezoelectric crystal (Piezoelectric Crystal) 10 and an organic light emitting diode display 20 electrically connected to the piezoelectric crystal 10. An organic light emitting diode display (Organic Light Emitting Diode display; OLED display) 20 may include a first electrode 22, a second electrode 26, and an organic thin film layer 24 located on the first electrode 22 and the second electrode Between 26. The piezoelectric crystal 10 may have a polished surface 10a. The surface 10a may face the human tissue 40 (Figure 1).

請參閱圖1，由於訊號接收與顯像系統106厚度為奈米級，其機械性質對於顯像的正確性，不會有影響。另一方面，壓電晶體10可以位在該有機發光二極體顯示器20和該超音波發射器30之間。該有機發光二極體顯示器20可以是例如，但不限於具有可塑性的有機發光二極體顯示器(Polymer light-emitting diodes；p-OLED)。具有可塑性的有機發光二極體顯示器，可以使所顯示的影像呈弧面，有助於提高人體內部的各種情況判讀的正確性。Please refer to FIG. 1.

圖3繪示兩種超音波檢測機操作步驟流程的比較示意圖。本創作的操作步驟流程，可以如圖3右方，包括訊號發射步驟102、訊號反射步驟104、以及訊號接收與顯像步驟106a。另一種常見超音波檢測機的操作步驟流程，可以如圖3左方，包括訊號發射步驟202、訊號反射步驟204、訊號轉換步驟205a、訊號處理步驟205b、以及顯像步驟206。常見超音波檢測機，至少比本創作多了訊號轉換步驟205a以及訊號處理步驟205b。其中，在訊號轉換步驟205a，是要將超音波訊號，轉換為電訊號。此外，在訊號處理步驟205b，是要將該電訊號，處理成數位訊號，以進行大量的電腦運算，進行後續的顯像步驟206。Figure 3 shows a schematic diagram of the comparison of the operating steps of the two ultrasonic detectors. The flow of the operation steps of this creation may be shown on the right in Figure 3, including a signal transmission step 102, a signal reflection step 104, and a signal reception and display step 106a. The flow of the operation steps of another common ultrasonic detector can be shown on the left side of FIG. 3, including a signal transmission step 202, a signal reflection step 204, a signal conversion step 205a, a signal processing step 205b, and a display step 206. Common ultrasonic detectors at least have more signal conversion steps 205a and signal processing steps 205b than the original creation. Among them, in the signal conversion step 205a, the ultrasonic signal is converted into an electrical signal. In addition, in the signal processing step 205b, the electrical signal is processed into a digital signal to perform a large number of computer operations and perform the subsequent visualization step 206.

由圖3左右比較可知，圖3右本創作的訊號接收與顯像系統(圖4)不需要將超音波訊號轉換為一電訊號(不需要訊號轉換步驟205a)，也不需要將該電訊號轉換為一數位訊號(不需要訊號處理步驟205b)。意即，本創作的系統106(圖1)同時具有訊號接收與顯像的功能，可以避免多餘的訊號轉換與處理成本。因此，本創作的超音波檢測機價格可以降低，達到使用普及的效果。From the comparison between the left and right of Figure 3, it can be seen that the signal receiving and display system created on the right of Figure 3 (Figure 4) does not need to convert the ultrasonic signal into an electrical signal (signal conversion step 205a is not required), nor does the electrical signal Converted to a digital signal (signal processing step 205b is not required). This means that the system 106 (FIG. 1) of the present invention has the functions of signal reception and display at the same time, which can avoid unnecessary signal conversion and processing costs. Therefore, the price of the ultrasonic detection machine created by this invention can be reduced to achieve the effect of popularization.
