以上所述僅係用以闡述本創作所欲解決的問題、解決問題的技術手段、及其產生的功效等等，本創作之具體細節將在下文的實施方式及相關圖式中詳細介紹。The above description is only used to explain the problem to be solved by this creation, the technical means to solve the problem, and the effects produced by it, etc. The specific details of this creation will be introduced in detail in the following embodiments and related drawings.

以下將以圖式揭露本創作之複數實施方式，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，熟悉本領域之技術人員應當瞭解到，在本創作部分實施方式中，這些實務上的細節並非必要的，因此不應用以限制本創作。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。另外，為了便於讀者觀看，圖式中各元件的尺寸並非依實際比例繪示。The plural implementations of this creation will be disclosed in the following diagrams. For the sake of clarity, many practical details will be explained in the following description. However, those skilled in the art should understand that in the implementation of this creation part, these practical details are not necessary, and therefore should not be used to limit this creation. In addition, in order to simplify the drawings, some conventionally used structures and elements will be shown in a simple schematic manner in the drawings. In addition, for the convenience of readers, the size of each element in the drawings is not drawn according to the actual scale.

第1圖係本創作一實施方式之顯示螢幕10的正視圖。第2圖係第1圖之顯示螢幕10的層疊結構200的剖視圖。在本實施方式中，如第1圖與第2圖所示，顯示螢幕10包括一外框100與一層疊結構200。外框100為口字型，並圍繞出一顯示區域110。外框100將層疊結構200固定於顯示區域110內，以保護層疊結構200。上述層疊結構200是透過一封膠結構(圖中未示)固定在一起，使得封膠結構圍繞上述層疊結構200之所有側邊。然而，本創作不限於此。Fig. 1 is a front view of the display screen 10 of an embodiment of the present invention. FIG. 2 is a cross-sectional view of the laminated structure 200 of the display screen 10 of FIG. 1. FIG. In this embodiment, as shown in FIG. 1 and FIG. 2, the display screen 10 includes an outer frame 100 and a laminated structure 200. The outer frame 100 has a mouth shape and surrounds a display area 110. The outer frame 100 fixes the laminated structure 200 in the display area 110 to protect the laminated structure 200. The above-mentioned laminated structure 200 is fixed together through an adhesive sealing structure (not shown in the figure), so that the sealing structure surrounds all sides of the above-mentioned laminated structure 200. However, this creation is not limited to this.

層疊結構200包含一智慧調光層210、一光穿透反射層220與一顯示模組230。光穿透反射層220為層疊於顯示模組230與智慧調光層210之間。顯示模組230能夠透過智慧調光層210及光穿透反射層220對外提供顯示影像。智慧調光層210用以依據接受供電與否，分別呈現出不同之第一態樣與第二態樣，換句話說，當智慧調光層210接受供電而成為第一態樣時，智慧調光層210被改變為透明，以外露出顯示模組230。當智慧調光層210停止接受供電而成為第二態樣時，智慧調光層210的顏色被改變以遮蔽顯示模組230。The laminated structure 200 includes a smart dimming layer 210, a light-transmitting reflective layer 220, and a display module 230. The light penetrating reflective layer 220 is laminated between the display module 230 and the smart dimming layer 210. The display module 230 can provide external display images through the smart dimming layer 210 and the light penetrating reflective layer 220. The smart dimming layer 210 is used to present different first and second states according to whether it receives power or not. In other words, when the smart dimming layer 210 receives power and becomes the first state, the smart dimming The optical layer 210 is changed to be transparent, and the display module 230 is exposed outside. When the smart dimming layer 210 stops receiving power and becomes the second state, the color of the smart dimming layer 210 is changed to cover the display module 230.

如此，由於停止運作之顯示螢幕10的顯示區域110為暗黑色，故，只要在第二態樣下之智慧調光層210能夠遮蔽顯示模組230以降低顯示螢幕10正面之突兀感，本創作能夠改善停止運作之顯示螢幕10的顯示區域110與其外框100在整體搭配下的視覺協調性，以達到使用滿意度與喜好度之目的。In this way, since the display area 110 of the display screen 10 that is not in operation is dark and black, as long as the smart dimming layer 210 in the second mode can shield the display module 230 to reduce the awkwardness on the front of the display screen 10, this creation It is possible to improve the visual coordination between the display area 110 of the display screen 10 that is not in operation and its outer frame 100 in the overall combination, so as to achieve the purpose of satisfaction and preference.

舉例來說，智慧調光層210包含一聚合物分散液晶單元(Polymer Dispersed Liquid Crystal，PDLC)，然而，本創作不限智慧調光層210的種類。具體來說，當聚合物分散液晶單元(PDLC)受到供電(即第一態樣)時，聚合物分散液晶單元(PDLC)成為透明；反之，當聚合物分散液晶單元被停止供電(即第二態樣)時，聚合物分散液晶單元之顏色皆為白色或灰白色，至少為不透明。For example, the smart dimming layer 210 includes a polymer dispersed liquid crystal cell (Polymer Dispersed Liquid Crystal, PDLC). However, the present invention is not limited to the type of the smart dimming layer 210. Specifically, when the polymer dispersed liquid crystal cell (PDLC) is supplied with power (that is, the first mode), the polymer dispersed liquid crystal cell (PDLC) becomes transparent; on the contrary, when the polymer dispersed liquid crystal cell is powered off (that is, the second mode) Aspect), the color of the polymer dispersed liquid crystal cell is white or off-white, at least opaque.

如此，更佳地，當外框100之顏色也設計為白色或灰白色時，由於外框100的顏色與智慧調光層210的顏色相同或大致相同，停止運作之顯示螢幕10的正面將呈現整體同色的效果，不致因顯示區域110為暗黑色而導致視覺突兀的狀況發生。In this way, more preferably, when the color of the outer frame 100 is also designed to be white or off-white, since the color of the outer frame 100 is the same or approximately the same as the color of the smart dimming layer 210, the front of the display screen 10 that is not functioning will appear as a whole The effect of the same color will not cause visual abruptness due to the dark black display area 110.

在本實施例中，光穿透反射層220為智慧調光層210上之鍍膜。舉例來說，鍍膜透過電鍍程序一體成形於智慧調光層210面向顯示模組230之一面。In this embodiment, the light penetrating reflective layer 220 is a coating on the smart dimming layer 210. For example, the plating film is integrally formed on the side of the smart dimming layer 210 facing the display module 230 through an electroplating process.

再者，在本實施例中，上述鍍膜為多層膜，且由複數個(如6層)彼此疊合之膜層所組成。更具體地，每個膜層例如為五氧化二鈮膜(Nb2O5)。然而，本創作不限於膜層之材料種類，其他實施例中，光穿透反射層220也可能只為一單層膜。更具體地，單層膜為一金屬單層膜，舉例來說，單層膜包含一鋁金屬透膜。然而，本創作不限於單層膜膜層之材料種類。Furthermore, in this embodiment, the above-mentioned plating film is a multi-layer film, and is composed of a plurality of (for example, 6 layers) laminated film layers. More specifically, each film layer is, for example, a niobium pentoxide film (Nb2O5). However, the present invention is not limited to the material type of the film layer. In other embodiments, the light penetrating reflective layer 220 may also be a single-layer film. More specifically, the single-layer film is a metal single-layer film, for example, the single-layer film includes an aluminum metal permeable film. However, this creation is not limited to the types of materials for single-layer films.

第3圖係第1圖之顯示螢幕10的方塊圖。如第2圖與第3圖所示，顯示螢幕10更包括一控制單元300與一電源單元400。控制單元300電連接智慧調光層210、顯示模組230與電源單元400。控制單元300用以指示電源分別對智慧調光層210與顯示模組230供電。當顯示模組230在顯示模組230停止運作時，同步對智慧調光層210停止供電，以致智慧調光層210呈現出第二態樣。此外，上述控制單元300不限為任意形式之硬體(例如CPU或GPU等控制電路)、軟體或韌體等。Figure 3 is a block diagram of the display screen 10 of Figure 1. As shown in FIGS. 2 and 3, the display screen 10 further includes a control unit 300 and a power supply unit 400. The control unit 300 is electrically connected to the smart dimming layer 210, the display module 230, and the power supply unit 400. The control unit 300 is used to instruct the power source to supply power to the smart dimming layer 210 and the display module 230 respectively. When the display module 230 stops operating when the display module 230 stops, the power supply to the smart dimming layer 210 is synchronously stopped, so that the smart dimming layer 210 assumes the second state. In addition, the above-mentioned control unit 300 is not limited to any form of hardware (for example, CPU or GPU control circuits), software or firmware.

更具體地，顯示模組230包含一顯示面板231與一背光模組232。例如，顯示面板231透過光學膠或水膠固定於光穿透反射層220上。背光模組232用以對顯示面板231提供顯示光線，顯示光線依序穿過光穿透反射層220與智慧調光層210。More specifically, the display module 230 includes a display panel 231 and a backlight module 232. For example, the display panel 231 is fixed on the light-transmitting reflective layer 220 through optical glue or water glue. The backlight module 232 is used to provide display light to the display panel 231, and the display light sequentially passes through the light penetrating reflective layer 220 and the smart dimming layer 210.

舉例來說，顯示面板231包含陣列基板、對向基板與液晶層(圖中未示)。液晶層介於陣列基板與對向基板之間。故透過施加電壓並產生電場於液晶層上，藉以決定液晶層之液晶分子的取向和入射光的偏振，從而顯示影像。此外，背光模組232例如為背光模組232或前光模組。舉例來說，背光模組232例如包含發光單元與導光模組。發光單元例如為發光二極體、微型發光二極體以及有機發光二極體等類似元件。導光模組例如為導光板或勻光板等。For example, the display panel 231 includes an array substrate, an opposite substrate, and a liquid crystal layer (not shown in the figure). The liquid crystal layer is interposed between the array substrate and the opposite substrate. Therefore, by applying a voltage and generating an electric field on the liquid crystal layer, the orientation of the liquid crystal molecules of the liquid crystal layer and the polarization of incident light are determined to display images. In addition, the backlight module 232 is, for example, a backlight module 232 or a front light module. For example, the backlight module 232 includes a light emitting unit and a light guide module. The light-emitting unit is, for example, a light-emitting diode, a miniature light-emitting diode, an organic light-emitting diode, and the like. The light guide module is, for example, a light guide plate or a light homogenizing plate.

此外，於第一模式時，即背光模組232開啟時，背光模組232所產生的光穿透光穿透反射層220之穿透率為40%~50%。於第二模式時，即背光模組232關閉時，外部的光被光穿透反射層220所反射之反射率為50%~60%。然而，本創作不限於此。其他實施例中，於第一模式時，光穿透反射層220之穿透率也可以為30%~70%或40%~60%等範圍。於第二模式時，光穿透反射層220之反射率也可以為50%~70%。In addition, in the first mode, that is, when the backlight module 232 is turned on, the transmittance of the light generated by the backlight module 232 through the reflective layer 220 is 40%-50%. In the second mode, that is, when the backlight module 232 is turned off, the reflectance of external light reflected by the light penetrating reflective layer 220 is 50%-60%. However, this creation is not limited to this. In other embodiments, in the first mode, the transmittance of light through the reflective layer 220 may also be in the range of 30% to 70% or 40% to 60%. In the second mode, the reflectance of the light penetrating the reflective layer 220 can also be 50% to 70%.

第4A圖與第4B圖分別係本實施方式之顯示螢幕10在智慧調光層210為第一態樣與第二態樣的使用示意圖。如第4A圖所示，當顯示模組230開始運作時，控制單元300指示電源對智慧調光層210供電，使得智慧調光層210被電致變色而成為清晰透明狀(第一態樣)，進而露出智慧調光層210下方之顯示模組230。如此，顯示模組230能夠透過智慧調光層210及光穿透反射層220對外提供顯示影像。故，由於顯示模組230之顯示光線L1能夠穿過光穿透反射層220與智慧調光層210，使用者能夠觀看到智慧調光層210下方之顯示模組230。FIG. 4A and FIG. 4B are respectively schematic diagrams of using the display screen 10 of the present embodiment in the first mode and the second mode on the smart dimming layer 210. As shown in FIG. 4A, when the display module 230 starts to operate, the control unit 300 instructs the power supply to supply power to the smart dimming layer 210, so that the smart dimming layer 210 is electrochromic and becomes clear and transparent (first aspect) , Thereby exposing the display module 230 under the smart dimming layer 210. In this way, the display module 230 can provide external display images through the smart dimming layer 210 and the light penetrating reflective layer 220. Therefore, since the display light L1 of the display module 230 can pass through the light penetrating reflective layer 220 and the smart dimming layer 210, the user can see the display module 230 under the smart dimming layer 210.

如第4B圖所示，當顯示模組230停止運作時，控制單元300指示電源停止對智慧調光層210供電，使得智慧調光層210的顏色被改變以遮蔽智慧調光層210下方之顯示模組230(第二態樣)。故，由於一部分之外界環境光L2被智慧調光層210所反射，另一部分之外界環境光L3被光穿透反射層220所反射層，故，智慧調光層210遮蔽了顯示模組230，進而讓使用者無法觀看到智慧調光層210下方之顯示模組230。更佳地，由於外框100之顏色與智慧調光層210之顏色皆為同色，停止運作之顯示螢幕10的正面將呈現整體同色的效果，不致因顯示區域110為暗黑色而導致視覺突兀的狀況發生。As shown in Figure 4B, when the display module 230 stops operating, the control unit 300 instructs the power supply to stop supplying power to the smart dimming layer 210, so that the color of the smart dimming layer 210 is changed to cover the display under the smart dimming layer 210 Module 230 (second aspect). Therefore, since a part of the outer boundary ambient light L2 is reflected by the smart dimming layer 210, and another part of the outer boundary ambient light L3 is reflected by the light penetrating reflective layer 220, the smart dimming layer 210 shields the display module 230. In turn, the user cannot see the display module 230 under the smart dimming layer 210. More preferably, since the color of the outer frame 100 and the color of the smart dimming layer 210 are both the same color, the front of the display screen 10 that is not operating will have the same color as a whole, so that the display area 110 is dark and black, which may cause visual abruptness. The situation occurs.

最後，上述所揭露之各實施例中，並非用以限定本創作，任何熟習此技藝者，在不脫離本創作之精神和範圍內，當可作各種之更動與潤飾，皆可被保護於本創作中。因此本創作之保護範圍當視後附之申請專利範圍所界定者為準。Finally, the various embodiments disclosed above are not intended to limit the creation. Anyone who is familiar with this technique can make various changes and modifications without departing from the spirit and scope of the creation, and they can all be protected in this creation.
