在附圖中,為了清楚起見,放大了層、膜、面板、區域 等的厚度。在整個說明書中,相同的附圖標記表示相同的元件。應當理解,當諸如層、膜、區域或基板的元件被稱為在另一元件”上”或”連接到”另一元件時,其可以直接在另一元件上或與另一元件連接,或者中間元件可以也存在。相反,當元件被稱為”直接在另一元件上”或”直接連接到”另一元件時,不存在中間元件。如本文所使用的,”連接”可以指物理及/或電性連接。再者,”電性連接”或”耦合”係可為二元件間存在其它元件。 In the drawings, the thickness of layers, films, panels, regions, etc., is exaggerated for clarity. Throughout the specification, the same figure reference numerals represent the same elements. It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to another element, or an intermediate element may also exist. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intermediate elements. As used herein, "connected" may refer to physical and/or electrical connections. Furthermore, "electrical connection" or "coupling" may be the presence of other elements between two elements.
這裡使用的術語僅僅是為了描述特定實施例的目的,而不是限制性的。如本文所使用的,除非內容清楚地指示,否則單數形式”一”、”一個”和”該”旨在包括複數形式,包括”至少一個”。”或”表示”及/或”。如本文所使用的,術語”及/或”包括一個或多個相關所列項目的任何和所有組合。還應當理解,當在本說明書中使用時,術語”包括”及/或”包括”指定所述特徵、區域、整體、步驟、操作、元件的存在及/或部件,但不排除一個或多個其它特徵、區域整體、步驟、操作、元件、部件及/或其組合的存在或添加。 The terms used herein are for the purpose of describing specific embodiments only and are not limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms, including "at least one". " or "means" and/or". As used herein, the term "and/or" includes any and all combinations of one or more of the relevant listed items. It should also be understood that when used in this specification, the term "includes" and/or "includes" specifies the presence of the features, regions, wholes, steps, operations, elements, and/or parts, but does not exclude the presence or addition of one or more other features, regions, wholes, steps, operations, elements, parts, and/or combinations thereof.
此外,諸如”下”或”底部”和”上”或”頂部”的相對術語可在本文中用於描述一個元件與另一元件的關係,如圖所示。應當理解,相對術語旨在包括除了圖中所示的方位之外的裝置的不同方位。例如,如果一個附圖中的裝置翻轉,則被描述為在其他元件的”下”側的元件將被定向在其他元件的”上”側。因此,示例性術語”下”可以包括”下”和”上”的取向,取決於附圖的特定取向。類似地,如果一個附圖中的裝置翻轉,則被描述為在其它元件”下方”或”下方”的元件將被定向為 在其它元件”上方”。因此,示例性術語”下面”或”下面”可以包括上方和下方的取向。 Additionally, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe the relationship of one element to another element, as shown in the figures. It should be understood that relative terms are intended to include different orientations of the device in addition to the orientation shown in the figures. For example, if the device in one figure is flipped, then the elements described as being on the "lower" side of other elements will be oriented on the "upper" side of the other elements. Thus, the exemplary term "lower" can include both "lower" and "upper" orientations, depending on the particular orientation of the figure. Similarly, if the device in one figure is flipped, then the elements described as being "below" or "beneath" other elements will be oriented as being "above" other elements. Thus, the exemplary term "below" or "beneath" can include both "upper" and "lower" orientations.
本文使用的”約”、”近似”、或”實質上”包括所述值和在本領域普通技術人員確定的特定值的可接受的偏差範圍內的平均值,考慮到所討論的測量和與測量相關的誤差的特定數量(即,測量系統的限制)。例如,”約”可以表示在所述值的一個或多個標準偏差內,或±30%、±20%、±10%、±5%內。再者,本文使用的“約”、”近似”或“實質上”可依光學性質、蝕刻性質或其它性質,來選擇較可接受的偏差範圍或標準偏差,而可不用一個標準偏差適用全部性質。 As used herein, "approximately", "approximately", or "substantially" includes the stated value and the average value within an acceptable deviation range of a particular value determined by a person of ordinary skill in the art, taking into account the measurement in question and the specific amount of error associated with the measurement (i.e., the limitations of the measurement system). For example, "approximately" can mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5%. Furthermore, "approximately", "approximately", or "substantially" as used herein can select a more acceptable deviation range or standard deviation based on the optical properties, etching properties, or other properties, and can apply to all properties without using one standard deviation.
除非另有定義,本文使用的所有術語(包括技術和科學術語)具有與本發明所屬領域的普通技術人員通常理解的相同的含義。將進一步理解的是,諸如在通常使用的字典中定義的那些術語應當被解釋為具有與它們在相關技術和本發明的上下文中的含義一致的含義,並且將不被解釋為理想化的或過度正式的意義,除非本文中明確地這樣定義。 Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by ordinary technicians in the field to which the present invention belongs. It will be further understood that those terms as defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and the present invention, and will not be interpreted as an idealized or overly formal meaning unless expressly defined as such in this document.
請參照第1~2B圖,第1圖繪示依照本揭露一實施例之顯示裝置100的示意圖,第2A圖繪示於第一時點第1圖之顯示裝置100所顯示之畫面F的局部示意圖,第2B圖繪示於第二時點第2A圖之畫面F的示意圖。顯示裝置100例如是可應用於筆記型電腦、平板電腦、桌上型電腦、家電等各種有顯示需求的產品。 Please refer to Figures 1 to 2B. Figure 1 is a schematic diagram of a display device 100 according to an embodiment of the present disclosure. Figure 2A is a partial schematic diagram of a screen F displayed by the display device 100 of Figure 1 at a first time point. Figure 2B is a schematic diagram of the screen F of Figure 2A at a second time point. The display device 100 can be applied to various products with display requirements, such as laptops, tablet computers, desktop computers, and home appliances.
如第1圖所示,顯示裝置100包括顯示面板110及控制器120。如第2A圖所示,顯示面板110用以顯示畫面F,畫面F包括 第一區M1(例如是第2A圖所示之圍繞圖案區F1的環形粗框區域)、第二區N1(例如是第2A圖所示之被圖案區F1環繞的區域)及至少一圖案區F1(例如是第2A圖所示之無剖面區域,位於第一區M1與第二區N1之間的區域)、。第一區M1鄰接圖案區F1。第一區M1包括數個第一區塊M11。控制器120用以:在第一時點,如第2A圖所示,控制此些第一區塊M11中相鄰之第一者M11a與及第二者M11b分別顯示相異的第一灰階亮度(灰階值)G11及第二灰階亮度G12;以及,在第二時點,如第2B圖所示,控制第一者M11a及第二者M11b分別顯示相異的第三灰階亮度G13與第四灰階亮度G14。第一灰階亮度G11與第三灰階亮度G13相異,第一灰階亮度G11與第三灰階亮度G13的平均值大致上等於背景灰階亮度GB,且第二灰階亮度G12與第四灰階亮度G14的平均值大致上等於背景灰階亮度GB。透過第一區M1之灰階變化設計,能增加第一區M1與圖案區F1的對比度(灰階差),使攝像器(未繪示)能清楚辨識畫面F在二時點的灰階度變化,而能拍攝到清楚的圖案區F1。 As shown in FIG. 1, the display device 100 includes a display panel 110 and a controller 120. As shown in FIG. 2A, the display panel 110 is used to display a screen F, and the screen F includes a first area M1 (e.g., the annular thick frame area surrounding the pattern area F1 shown in FIG. 2A), a second area N1 (e.g., the area surrounded by the pattern area F1 shown in FIG. 2A) and at least one pattern area F1 (e.g., the non-section area shown in FIG. 2A, the area between the first area M1 and the second area N1). The first area M1 is adjacent to the pattern area F1. The first area M1 includes a plurality of first blocks M11. The controller 120 is used to: at a first time point, as shown in FIG. 2A, control the adjacent first M11a and second M11b in the first blocks M11 to respectively display different first grayscale brightness (grayscale value) G11 and second grayscale brightness G12; and at a second time point, as shown in FIG. 2B, control the first M11a and second M11b to respectively display different third grayscale brightness G13 and fourth grayscale brightness G14. The first grayscale brightness G11 is different from the third grayscale brightness G13, and the average value of the first grayscale brightness G11 and the third grayscale brightness G13 is substantially equal to the background grayscale brightness GB, and the average value of the second grayscale brightness G12 and the fourth grayscale brightness G14 is substantially equal to the background grayscale brightness GB. Through the grayscale change design of the first area M1, the contrast (grayscale difference) between the first area M1 and the pattern area F1 can be increased, so that the camera (not shown) can clearly identify the grayscale changes of the picture F at two points in time and can capture a clear pattern area F1.
如第2A圖所示,背景灰階亮度GB例如是鄰接第一區M1之數個畫素(pixel)之一者(例如,第2A圖之畫素P1)的顯示灰階亮度。畫面F中不同區域的背景灰階亮度GB可相異。 As shown in FIG. 2A , the background grayscale brightness GB is, for example, the display grayscale brightness of one of the pixels adjacent to the first region M1 (for example, the pixel P1 in FIG. 2A ). The background grayscale brightness GB of different regions in the frame F may be different.
雖然第1圖有繪示出圖案區F1及第一區M1的外觀,然畫面的掃描頻率可大於人眼所能辨識的頻閃頻率(Flicker Frequency),使人眼難以或無法辨識在二時點的圖案區F1及第一區M1的閃爍變化。 Although Figure 1 shows the appearance of the pattern area F1 and the first area M1, the scanning frequency of the screen may be greater than the flicker frequency that the human eye can discern, making it difficult or impossible for the human eye to discern the flicker changes of the pattern area F1 and the first area M1 at two points in time.
前述第一者M11a及第二者M11b分別是數個或所有第一區塊M11中任相鄰二者。在實施例中,在一時點,第一區M1的數個或所有第一區塊M11中任相鄰二者的灰階亮度相異,使第一區M1為馬賽克圖案區。馬賽克圖案區能降低人眼對圖案區F1的辨識度。此外,一個第一區塊M11可對應顯示面板110的數個畫素之一者或一些。另外,本文之第一時點及第二時點分別表示畫面F顯示過程的數個時點的任相鄰二者,其中相鄰二時點的時間間隔可視畫面掃描頻率而定,本發明實施例不加以限定。 The aforementioned first M11a and second M11b are any two adjacent ones in several or all first blocks M11. In the embodiment, at a time point, the grayscale brightness of any two adjacent ones in several or all first blocks M11 of the first area M1 is different, so that the first area M1 is a mosaic pattern area. The mosaic pattern area can reduce the recognition of the pattern area F1 by the human eye. In addition, a first block M11 can correspond to one or some of the several pixels of the display panel 110. In addition, the first time point and the second time point in this article respectively represent any two adjacent ones of several time points in the display process of the screen F, wherein the time interval between the two adjacent time points can be determined according to the screen scanning frequency, and the embodiment of the present invention is not limited.
此外,馬賽克圖案區之一區塊(例如,第一者M11a)在二時點的二灰階亮度分別為較高灰階亮度(例如,第三灰階亮度G13)及較低灰階亮度(例如,第一灰階亮度G11),其中較高灰階亮度及較低灰階亮度依據背景灰階亮度GB而定。例如,透過查表、曲線或方程式,可取得對應背景灰階亮度GB之一組較高灰階亮度及較低灰階亮度。 In addition, the two grayscale brightnesses of a block of the mosaic pattern area (e.g., the first one M11a) at two time points are respectively a higher grayscale brightness (e.g., the third grayscale brightness G13) and a lower grayscale brightness (e.g., the first grayscale brightness G11), wherein the higher grayscale brightness and the lower grayscale brightness are determined according to the background grayscale brightness GB. For example, a set of higher grayscale brightness and lower grayscale brightness corresponding to the background grayscale brightness GB can be obtained by looking up a table, a curve or an equation.
在本實施例中,圖案區F1例如是文字、字母、符號、數字或其它由直線、曲線或其組合之圖案等。圖案區F1也可稱為浮水印。第一區M1鄰接圖案區F1之外邊緣,其形狀可順應圖案區F1之外邊緣之形狀。在一實施例中,第一區M1可鄰接圖案區F1之整個外輪廓之至少一部分。在另一實施例中,第一區M1可鄰接圖案區F1之內邊緣,其形狀可順應圖案區F1之內邊緣之形狀,且第一區M1可鄰接圖案區F1之整個內輪廓之至少一部分。 In this embodiment, the pattern area F1 is, for example, text, letters, symbols, numbers, or other patterns consisting of straight lines, curves, or a combination thereof. The pattern area F1 can also be called a watermark. The first area M1 is adjacent to the outer edge of the pattern area F1, and its shape can conform to the shape of the outer edge of the pattern area F1. In one embodiment, the first area M1 can be adjacent to at least a portion of the entire outer contour of the pattern area F1. In another embodiment, the first area M1 can be adjacent to the inner edge of the pattern area F1, and its shape can conform to the shape of the inner edge of the pattern area F1, and the first area M1 can be adjacent to at least a portion of the entire inner contour of the pattern area F1.
在一實施例中,第一灰階亮度G11與第三灰階亮度G13 的平均值大致上等於背景灰階亮度GB,因此,在視覺上,第一區M1在二時點的顯示灰階與背景灰階亮度GB大致相等,使人眼難以辨識第一區M1在二時點的灰階變化。在一實施例中,第一灰階亮度G11與第三灰階亮度G13可實質上相等,例如,第一灰階亮度G11及第三灰階亮度G13皆等於背景灰階亮度GB。在另一實施例中,第一灰階亮度G11與第三灰階亮度G13可相異,而第一灰階亮度G11與第三灰階亮度G13的平均值大致上等於背景灰階亮度GB。綜上可知,只要第一灰階亮度G11與第三灰階亮度G13的平均值大致上等於背景灰階亮度GB即可,第三灰階亮度G13可大於、小於或等於第一灰階亮度G11。 In one embodiment, the average value of the first grayscale brightness G11 and the third grayscale brightness G13 is substantially equal to the background grayscale brightness GB. Therefore, visually, the displayed grayscale of the first area M1 at two points in time is substantially equal to the background grayscale brightness GB, making it difficult for the human eye to discern the grayscale change of the first area M1 at two points in time. In one embodiment, the first grayscale brightness G11 and the third grayscale brightness G13 may be substantially equal, for example, the first grayscale brightness G11 and the third grayscale brightness G13 are both equal to the background grayscale brightness GB. In another embodiment, the first grayscale brightness G11 and the third grayscale brightness G13 may be different, and the average value of the first grayscale brightness G11 and the third grayscale brightness G13 is substantially equal to the background grayscale brightness GB. In summary, as long as the average value of the first grayscale brightness G11 and the third grayscale brightness G13 is roughly equal to the background grayscale brightness GB, the third grayscale brightness G13 can be greater than, less than or equal to the first grayscale brightness G11.
在一實施例中,第二灰階亮度G12與第四灰階亮度G14的平均值大致上等於背景灰階亮度GB,如此,在視覺上,第一區M1在二時點的顯示灰階與背景灰階亮度GB大致相等,使人眼難以辨識第一區M1在二時點的灰階變化。在一實施例中,第二灰階亮度G12及第四灰階亮度G14可實質上相等,例如,第二灰階亮度G12及第四灰階亮度G14皆等於背景灰階亮度GB。在另一實施例中,第二灰階亮度G12與第四灰階亮度G14可相異,而第二灰階亮度G12與第四灰階亮度G14的平均值大致上等於背景灰階亮度GB。綜上可知,只要第二灰階亮度G12與第四灰階亮度G14的平均值大致上等於背景灰階亮度GB即可,第二灰階亮度G12可大於、小於或等於第四灰階亮度G14。 In one embodiment, the average value of the second grayscale brightness G12 and the fourth grayscale brightness G14 is substantially equal to the background grayscale brightness GB. Thus, visually, the display grayscale of the first area M1 at two points in time is substantially equal to the background grayscale brightness GB, making it difficult for the human eye to discern the grayscale change of the first area M1 at two points in time. In one embodiment, the second grayscale brightness G12 and the fourth grayscale brightness G14 may be substantially equal, for example, the second grayscale brightness G12 and the fourth grayscale brightness G14 are both equal to the background grayscale brightness GB. In another embodiment, the second grayscale brightness G12 and the fourth grayscale brightness G14 may be different, and the average value of the second grayscale brightness G12 and the fourth grayscale brightness G14 is substantially equal to the background grayscale brightness GB. In summary, as long as the average value of the second grayscale brightness G12 and the fourth grayscale brightness G14 is roughly equal to the background grayscale brightness GB, the second grayscale brightness G12 can be greater than, less than or equal to the fourth grayscale brightness G14.
如第2A及2B圖所示,圖案區F1包括數個圖案區塊 F11。控制器120更用以:在第一時點,如第2A圖所示,控制各圖案區塊F11顯示第一圖案灰階亮度GF11,以及,在第二時點,如第2B圖所示,控制各圖案區塊F11顯示第三圖案灰階亮度GF13,其中第一圖案灰階亮度GF11與第三圖案灰階亮度GF13相異。在一實施例中,第一圖案灰階亮度GF11與第三圖案灰階亮度GF13的平均值大致上等於背景灰階亮度GB。如此,在視覺上,圖案區F1在二時點的顯示灰階與背景灰階亮度GB大致相等,使人眼難以辨識圖案區F1在二時點的灰階變化。 As shown in Figures 2A and 2B, the pattern area F1 includes several pattern blocks F11. The controller 120 is further used to: at a first time point, as shown in Figure 2A, control each pattern block F11 to display a first pattern grayscale brightness GF11, and at a second time point, as shown in Figure 2B, control each pattern block F11 to display a third pattern grayscale brightness GF13, wherein the first pattern grayscale brightness GF11 is different from the third pattern grayscale brightness GF13. In one embodiment, the average value of the first pattern grayscale brightness GF11 and the third pattern grayscale brightness GF13 is substantially equal to the background grayscale brightness GB. In this way, visually, the display grayscale of the pattern area F1 at two time points is substantially equal to the background grayscale brightness GB, making it difficult for the human eye to recognize the grayscale change of the pattern area F1 at two time points.
如第2A及2B圖所示,第二區N1鄰接圖案區F1,例如鄰接圖案區F1之內邊緣,其形狀可順應圖案區F1之內邊緣之形狀。在一實施例中,第二區N1鄰接圖案區F1之整個內輪廓之至少一部分。前述圖案區F1位於第二區N1與第一區M1之間。在另一實施例中,第二區N1可鄰接圖案區F1之外邊緣,其形狀可順應圖案區F1之外邊緣之形狀,且第二區M2可鄰接圖案區F1之整個外輪廓之至少一部分。 As shown in Figures 2A and 2B, the second area N1 is adjacent to the pattern area F1, for example, adjacent to the inner edge of the pattern area F1, and its shape can conform to the shape of the inner edge of the pattern area F1. In one embodiment, the second area N1 is adjacent to at least a portion of the entire inner contour of the pattern area F1. The aforementioned pattern area F1 is located between the second area N1 and the first area M1. In another embodiment, the second area N1 can be adjacent to the outer edge of the pattern area F1, and its shape can conform to the shape of the outer edge of the pattern area F1, and the second area M2 can be adjacent to at least a portion of the entire outer contour of the pattern area F1.
如第2A及2B圖所示,第二區N1包括數個第二區塊N11。控制器120用以:在第一時點,如第2A圖所示,控制此些第二區塊N11中相鄰之第一者N11a與及第二者N11b分別顯示相異的第五灰階亮度G15與第六灰階亮度G16;以及,在第二時點,如第2B圖所示,控制第一者N11a及第二者N11b分別顯示相異的第七灰階亮度G17與第八灰階亮度G18。第五灰階亮度G15與第七灰階亮度G17相異,第五灰階亮度G15與第七灰階亮度G17的平均值大致上等於背 景灰階亮度GB,且第六灰階亮度G16與第八灰階亮度G18的平均值大致上等於背景灰階亮度GB。透過第二區N1及圖案區F1之灰階變化設計,能增加第二區N1與圖案區F1的對比度,使攝像器(未繪示)能清楚辨識畫面F在二時點的灰階度變化,而能拍攝到清楚的圖案區F1。 As shown in FIGS. 2A and 2B , the second area N1 includes a plurality of second blocks N11. The controller 120 is used to: at a first time point, as shown in FIG. 2A , control the adjacent first N11a and second N11b in the second blocks N11 to respectively display the fifth grayscale brightness G15 and the sixth grayscale brightness G16; and at a second time point, as shown in FIG. 2B , control the first N11a and the second N11b to respectively display the seventh grayscale brightness G17 and the eighth grayscale brightness G18. The fifth grayscale brightness G15 is different from the seventh grayscale brightness G17. The average value of the fifth grayscale brightness G15 and the seventh grayscale brightness G17 is substantially equal to the background grayscale brightness GB, and the average value of the sixth grayscale brightness G16 and the eighth grayscale brightness G18 is substantially equal to the background grayscale brightness GB. Through the grayscale change design of the second area N1 and the pattern area F1, the contrast between the second area N1 and the pattern area F1 can be increased, so that the camera (not shown) can clearly identify the grayscale change of the picture F at two points in time, and can capture a clear pattern area F1.
第五灰階亮度G15、第六灰階亮度G16、第七灰階亮度G17及第八灰階亮度G18的關係可類似或同於前述第一灰階亮度與G11、第二灰階亮度G12、第三灰階亮度G13及第四灰階亮度G14的關係,於此不再贅述。 The relationship between the fifth grayscale brightness G15, the sixth grayscale brightness G16, the seventh grayscale brightness G17 and the eighth grayscale brightness G18 can be similar or the same as the relationship between the first grayscale brightness G11, the second grayscale brightness G12, the third grayscale brightness G13 and the fourth grayscale brightness G14, which will not be elaborated here.
在實施例中,在任一時點,第二區N1的數個或所有第二區塊N11中任相鄰二者的灰階亮度相異,使第二區N1為馬賽克圖案區。此外,一個第二區塊N11可對應顯示面板110的數畫素之一者或一些。 In an embodiment, at any time point, the grayscale brightness of any two adjacent ones of several or all second blocks N11 of the second area N1 is different, so that the second area N1 is a mosaic pattern area. In addition, a second block N11 may correspond to one or some of the digital pixels of the display panel 110.
透過第一區M1、圖案區F1及第二區N1的灰階度設計,能增加圖案區F1相較於第一區M1及與第二區N1的對比度,使攝像器(未繪示)能清楚辨識畫面F在二時點的灰階度變化,而能拍攝到更清楚的圖案區F1。 Through the grayscale design of the first area M1, the pattern area F1 and the second area N1, the contrast of the pattern area F1 compared to the first area M1 and the second area N1 can be increased, so that the camera (not shown) can clearly identify the grayscale changes of the picture F at two points in time and can capture a clearer pattern area F1.
請參照第3A~3B圖,第3A圖繪示於依照本發明另一實施例之於第一時點顯示裝置所顯示畫面F的的局部示意圖,而第3B圖繪示於第二時點第3A圖之畫面F的示意圖。 Please refer to Figures 3A-3B. Figure 3A is a partial schematic diagram of a screen F displayed by a display device at a first time point according to another embodiment of the present invention, and Figure 3B is a schematic diagram of screen F of Figure 3A at a second time point.
與第2A圖之圖案區F1不同的是,本實施例之圖案區F2為馬賽克圖案區。 Different from the pattern area F1 in FIG. 2A, the pattern area F2 in this embodiment is a mosaic pattern area.
如第3A圖所示,本實施例之畫面F包括第一區M2(例如是第3A圖所示之圍繞圖案區F2的環形粗框區域)、第二區N2(例如是第3A圖所示之被圖案區F2環繞的區域)及至少一圖案區F2(例如是第3A圖所示之無剖面區域,位於第一區M2與第二區N2之間的區域)。圖案區F2包括數個圖案區塊F21。本實施例中,控制器120用以:在第一時點,如第3A圖所示,控制此些圖案區塊F21中相鄰之第三者F21a與第四者F21b分別顯示相異的第一圖案灰階亮度GF21與第二圖案灰階亮度GF22;以及,在第二時點,如第3B圖所示,第三者F21a及第四者F21b分別顯示相異的第三圖案灰階亮度GF23及第四圖案灰階亮度GF24。在本實施例中,第一圖案灰階亮度GF21與第三圖案灰階亮度GF23相異,第一圖案灰階亮度GF21與第三圖案灰階亮度GF23的平均值等於背景灰階亮度GB,且第二圖案灰階亮度GF22與第四圖案灰階亮度GF24的平均值等於背景灰階亮度GB。如此,透過圖案區F1之灰階變化設計,能增加第一區M1與圖案區F1的對比度,使攝像器(未繪示)能清楚辨識畫面F在二時點的灰階度變化,而能拍攝到清楚的圖案區F2。 As shown in FIG. 3A , the screen F of this embodiment includes a first area M2 (e.g., the thick-framed annular area surrounding the pattern area F2 shown in FIG. 3A ), a second area N2 (e.g., the area surrounded by the pattern area F2 shown in FIG. 3A ) and at least one pattern area F2 (e.g., the non-section area shown in FIG. 3A , the area between the first area M2 and the second area N2 ). The pattern area F2 includes a plurality of pattern blocks F21 . In this embodiment, the controller 120 is used to: at a first time point, as shown in FIG. 3A , control the adjacent third party F21a and fourth party F21b in these pattern blocks F21 to respectively display different first pattern grayscale brightness GF21 and second pattern grayscale brightness GF22; and, at a second time point, as shown in FIG. 3B , the third party F21a and fourth party F21b to respectively display different third pattern grayscale brightness GF23 and fourth pattern grayscale brightness GF24. In this embodiment, the first pattern grayscale brightness GF21 is different from the third pattern grayscale brightness GF23, and the average value of the first pattern grayscale brightness GF21 and the third pattern grayscale brightness GF23 is equal to the background grayscale brightness GB, and the average value of the second pattern grayscale brightness GF22 and the fourth pattern grayscale brightness GF24 is equal to the background grayscale brightness GB. In this way, through the grayscale change design of the pattern area F1, the contrast between the first area M1 and the pattern area F1 can be increased, so that the camera (not shown) can clearly identify the grayscale change of the picture F at two points in time, and can capture a clear pattern area F2.
在本實施例中,第二圖案灰階亮度GF22與第四圖案灰階亮度GF24大致上相等。在另一實施例中,第二圖案灰階亮度GF22與第四圖案灰階亮度GF24可相異。然,只要第二圖案灰階亮度GF22與第四圖案灰階亮度GF24的平均值等於背景灰階亮度GB,第二圖案灰階亮度GF22可大於、等於或小於第二圖案灰階亮度GF22。 In this embodiment, the second pattern grayscale brightness GF22 and the fourth pattern grayscale brightness GF24 are substantially equal. In another embodiment, the second pattern grayscale brightness GF22 and the fourth pattern grayscale brightness GF24 may be different. However, as long as the average value of the second pattern grayscale brightness GF22 and the fourth pattern grayscale brightness GF24 is equal to the background grayscale brightness GB, the second pattern grayscale brightness GF22 may be greater than, equal to, or less than the second pattern grayscale brightness GF22.
此外,第一圖案灰階亮度GF21與第二圖案灰階亮度 GF22的平均值不等於背景灰階亮度GB,且第三圖案灰階亮度GF23與第四圖案灰階亮度GF24的平均值不等於背景灰階亮度GB。 In addition, the average values of the first pattern grayscale brightness GF21 and the second pattern grayscale brightness GF22 are not equal to the background grayscale brightness GB, and the average values of the third pattern grayscale brightness GF23 and the fourth pattern grayscale brightness GF24 are not equal to the background grayscale brightness GB.
第二圖案灰階亮度GF22與第四圖案灰階亮度GF24的平均值等於背景灰階亮度GB。如此,在視覺上,圖案區F2在二時點的顯示灰階與背景灰階亮度GB大致相等,使人眼難以辨識圖案區F2在二時點的灰階變化。 The average value of the second pattern grayscale brightness GF22 and the fourth pattern grayscale brightness GF24 is equal to the background grayscale brightness GB. Thus, visually, the displayed grayscale of the pattern area F2 at two points in time is roughly equal to the background grayscale brightness GB, making it difficult for the human eye to discern the grayscale changes of the pattern area F2 at two points in time.
如第3A圖所示,第一區M2包括數個第一區塊M21。在本實施例中,控制器120用以:在第一時點,如第3A圖所示,控制各第一區塊M21顯示第一灰階亮度與G21;以及,在第二時點,如第3B圖所示,控制各第一區塊M21顯示第三灰階亮度與G23。在一實施例中,第一灰階亮度與G21與第三灰階亮度與G23相異,然亦可大致上相等。只要第一灰階亮度與G21與第三灰階亮度與G23的平均值大致上等於背景灰階亮度GB即可,第一灰階亮度與G21可大於、等於或小於第三灰階亮度與G23。 As shown in FIG. 3A, the first area M2 includes a plurality of first blocks M21. In this embodiment, the controller 120 is used to: at a first time point, as shown in FIG. 3A, control each first block M21 to display the first grayscale brightness G21; and at a second time point, as shown in FIG. 3B, control each first block M21 to display the third grayscale brightness G23. In one embodiment, the first grayscale brightness G21 and the third grayscale brightness G23 are different, but can also be substantially equal. As long as the average value of the first grayscale brightness G21 and the third grayscale brightness G23 is substantially equal to the background grayscale brightness GB, the first grayscale brightness G21 can be greater than, equal to, or less than the third grayscale brightness G23.
如第3A圖所示,第二區N2包括數個第二區塊N21。在本實施例中,控制器120用以:在第一時點,如第3A圖所示,控制各第二區塊N21顯示第五灰階亮度G25;以及,在第二時點,如第3B圖所示,控制各第二區塊N21顯示第七灰階亮度與G27。在一實施例中,第五灰階亮度G25與第七灰階亮度與G27大致上相等,然亦可大致上相異。只要第五灰階亮度G25與第七灰階亮度G27的平均值大致上等於背景灰階亮度GB即可,第一灰階亮度G21可大於、等於或小於第三灰階亮度G23。 As shown in FIG. 3A, the second area N2 includes a plurality of second blocks N21. In this embodiment, the controller 120 is used to: at a first time point, as shown in FIG. 3A, control each second block N21 to display the fifth grayscale brightness G25; and at a second time point, as shown in FIG. 3B, control each second block N21 to display the seventh grayscale brightness G27. In one embodiment, the fifth grayscale brightness G25 and the seventh grayscale brightness G27 are substantially equal, but may also be substantially different. As long as the average value of the fifth grayscale brightness G25 and the seventh grayscale brightness G27 is substantially equal to the background grayscale brightness GB, the first grayscale brightness G21 may be greater than, equal to, or less than the third grayscale brightness G23.
請參照第4A~4B圖,第4A圖繪示於依照本發明另一實施例之於第一時點顯示裝置所顯示畫面F的局部示意圖,而第4B圖繪示於第二時點第4A圖之畫面F的示意圖。 Please refer to Figures 4A-4B. Figure 4A is a partial schematic diagram of a screen F displayed by a display device at a first time point according to another embodiment of the present invention, and Figure 4B is a schematic diagram of screen F of Figure 4A at a second time point.
如第4A圖所示,本實施例之畫面F包括第一區M3(例如是第4A圖所示之圍繞圖案區F2的環形粗框區域)、第二區N2(例如是第4A圖所示之被圖案區F2環繞的區域)及至少一圖案區F2(例如是第4A圖所示之無剖面區域,位於第一區M3與第二區N2之間的區域)。本實施例之畫面F之具有與第3A圖之畫面F相同或相似特徵,不同處之一例如是,本實施例之第一區M3為馬賽克圖案區。如第4A圖所示,第一區M3具有類似或同於第2A圖之第一區M1的灰階設計,於此不再贅述。 As shown in FIG. 4A, the screen F of this embodiment includes a first area M3 (e.g., the thick annular frame area surrounding the pattern area F2 shown in FIG. 4A), a second area N2 (e.g., the area surrounded by the pattern area F2 shown in FIG. 4A) and at least one pattern area F2 (e.g., the non-section area shown in FIG. 4A, the area between the first area M3 and the second area N2). The screen F of this embodiment has the same or similar features as the screen F of FIG. 3A, and one of the differences is that the first area M3 of this embodiment is a mosaic pattern area. As shown in FIG. 4A, the first area M3 has a grayscale design similar to or the same as the first area M1 of FIG. 2A, which will not be repeated here.
請參照第5A~5C及6A~6B圖,第5A圖繪示依照本發明另一實施例之於第一時點顯示裝置100所顯示畫面F之局部示意圖,第5B圖繪示於第二時點第5A圖之畫面F之示意圖,第5C圖繪示於第三時點第5A圖之畫面F之示意圖,第6A圖繪示圖案區塊於第5A~5C圖之不同時點之灰階亮度變化示意圖,而第6B圖繪示第5A~5C圖之圖案區塊於不同時點之灰階亮度的平均示意圖。 Please refer to Figures 5A-5C and 6A-6B.

如第5A圖所示,畫面F包括至少一圖案區F4及第一區(或稱「背景區」)M4,其中圖案區F4包括數個圖案區塊F41。 As shown in Figure 5A, the frame F includes at least one pattern area F4 and a first area (or "background area") M4, wherein the pattern area F4 includes a plurality of pattern blocks F41.
控制器120用以:如第5A圖所示,在第一時點T1,控制此些圖案區塊F41之第一者F41a、第二者F41b及第三者F41c分別顯示相異的第一圖案灰階亮度GF41、第二圖案灰階亮度GF42與 第三圖案灰階亮度GF43;如第5B圖所示,在第二時點T2,控制第一者F41a、第二者F41b及第三者F41c分別顯示相異的第四圖案灰階亮度GF44、第五圖案灰階亮度GF45與第六圖案灰階亮度GF46;以及,如第5C圖所示,在第三時點T3,控制第一者F41a、第二者F41b及第三者F41c分別顯示相異的第七圖案灰階亮度GF47、第八圖案灰階亮度GF48與第九圖案灰階亮度GF49。 The controller 120 is used to: as shown in FIG. 5A, at a first time point T1, control the first F41a, the second F41b and the third F41c of the pattern blocks F41 to display different first pattern grayscale brightness GF41, second pattern grayscale brightness GF42 and third pattern grayscale brightness GF43 respectively; as shown in FIG. 5B, at a second time point T2, control the first F41a, the second F41b and the third F41c to display different first pattern grayscale brightness GF41, second pattern grayscale brightness GF42 and third pattern grayscale brightness GF43 respectively; The three F41cs respectively display the fourth pattern grayscale brightness GF44, the fifth pattern grayscale brightness GF45 and the sixth pattern grayscale brightness GF46; and, as shown in Figure 5C, at the third time point T3, the first F41a, the second F41b and the third F41c are controlled to respectively display the seventh pattern grayscale brightness GF47, the eighth pattern grayscale brightness GF48 and the ninth pattern grayscale brightness GF49.
如第5A~5C圖所示,第一者F41a環繞第二者F41b及第三者F41c,而第二者F41b環繞第三者F41c。在其它實施例中,第一者F41a、第二者F41b與第三者F41c之一者環繞第一者F41a、第二者F41b與第三者F41c之其餘二者。 As shown in Figures 5A to 5C, the first F41a surrounds the second F41b and the third F41c, and the second F41b surrounds the third F41c. In other embodiments, one of the first F41a, the second F41b, and the third F41c surrounds the other two of the first F41a, the second F41b, and the third F41c.
如第5A~5C圖所示,第一圖案灰階亮度GF41、第二圖案灰階亮度GF42與第三圖案灰階亮度GF43相異,第一圖案灰階亮度GF41、第二圖案灰階亮度GF42與第三圖案灰階亮度GF43的平均值等於背景灰階亮度GB,第四圖案灰階亮度GF44、第五圖案灰階亮度GF45與第六圖案灰階亮度GF46相異,第四圖案灰階亮度GF44、第五圖案灰階亮度GF45與第六圖案灰階亮度GF46的平均值等於背景灰階亮度GB,第七圖案灰階亮度GF47、第八圖案灰階亮度GF48與第九圖案灰階亮度GF49相異,且第七圖案灰階亮度GF47、第八圖案灰階亮度GF48與第九圖案灰階亮度GF49的平均值等於背景灰階亮度GB。 As shown in FIGS. 5A to 5C, the first pattern grayscale brightness GF41, the second pattern grayscale brightness GF42 and the third pattern grayscale brightness GF43 are different, and the average value of the first pattern grayscale brightness GF41, the second pattern grayscale brightness GF42 and the third pattern grayscale brightness GF43 is equal to the background grayscale brightness GB, the fourth pattern grayscale brightness GF44, the fifth pattern grayscale brightness GF45 and the sixth pattern grayscale brightness GF46 are different, and the The average value of the fourth pattern grayscale brightness GF44, the fifth pattern grayscale brightness GF45 and the sixth pattern grayscale brightness GF46 is equal to the background grayscale brightness GB, the seventh pattern grayscale brightness GF47, the eighth pattern grayscale brightness GF48 and the ninth pattern grayscale brightness GF49 are different, and the average value of the seventh pattern grayscale brightness GF47, the eighth pattern grayscale brightness GF48 and the ninth pattern grayscale brightness GF49 is equal to the background grayscale brightness GB.
如第5A~5C圖所示,相鄰二時點之二圖案區塊F41的灰階亮度相異。 As shown in Figures 5A to 5C, the grayscale brightness of two pattern blocks F41 at two adjacent time points is different.
如第6A圖所示,第5A圖之畫面F持續第一時間區間△T1,第5B圖之畫面F持續第二時間區間△T2,而第5C圖之畫面F持續第三時間區間△T3。第一時間區間△T1,第二時間區間△T2及第三時間區間△T3例如是1/360秒,然亦可更長或更短。第一時間區間△T1,第二時間區間△T2與第三時間區間△T3之總和為一個週期,如1/120秒。 As shown in Figure 6A, the frame F of Figure 5A lasts for the first time interval △T1, the frame F of Figure 5B lasts for the second time interval △T2, and the frame F of Figure 5C lasts for the third time interval △T3. The first time interval △T1, the second time interval △T2, and the third time interval △T3 are, for example, 1/360 seconds, but may also be longer or shorter. The sum of the first time interval △T1, the second time interval △T2, and the third time interval △T3 is a cycle, such as 1/120 seconds.
第6A圖之虛線表示習知畫面之灰階亮度,而第6A圖之粗線表示顯示裝置100所顯示之畫面的灰階亮度。以同一個圖案區塊F41c舉例來說,相較於習知畫面之灰階亮度變化,第5A圖之第三圖案灰階亮度GF43、第5B圖之第六圖案灰階亮度GF46與第5C圖之第九圖案灰階亮度GF49任二者之間的差異較小,因此閃爍值較小。 The dotted line in FIG. 6A represents the grayscale brightness of the known screen, and the bold line in FIG. 6A represents the grayscale brightness of the screen displayed by the display device 100. Taking the same pattern block F41c as an example, compared with the grayscale brightness change of the known screen, the difference between the third pattern grayscale brightness GF43 in FIG. 5A, the sixth pattern grayscale brightness GF46 in FIG. 5B, and the ninth pattern grayscale brightness GF49 in FIG. 5C is smaller, so the flicker value is smaller.
如第6B圖所示,以同一個圖案區塊來說,第5A~5C圖之數個灰階亮度的平均值同樣等於背景灰階亮度GB。如此,在視覺上,圖案區在二時點的顯示灰階與背景灰階亮度GB大致相等,使人眼難以辨識圖案區在二時點的灰階變化。 As shown in Figure 6B, for the same pattern block, the average value of the grayscale brightness of Figures 5A to 5C is also equal to the background grayscale brightness GB. In this way, visually, the displayed grayscale of the pattern area at two points in time is roughly equal to the background grayscale brightness GB, making it difficult for the human eye to discern the grayscale changes of the pattern area at two points in time.
如第5A~5C圖所示,第一圖案灰階亮度GF41、第四圖案灰階亮度GF44與第七圖案灰階亮度GF47相異,第二圖案灰階亮度GF42、第五圖案灰階亮度GF45與第八圖案灰階亮度GF48相異,而第三圖案灰階亮度GF43、第六圖案灰階亮度GF46與第九圖案灰階亮度GF49相異。 As shown in Figures 5A to 5C, the grayscale brightness of the first pattern GF41, the grayscale brightness of the fourth pattern GF44 and the grayscale brightness of the seventh pattern GF47 are different, the grayscale brightness of the second pattern GF42, the grayscale brightness of the fifth pattern GF45 and the grayscale brightness of the eighth pattern GF48 are different, and the grayscale brightness of the third pattern GF43, the grayscale brightness of the sixth pattern GF46 and the grayscale brightness of the ninth pattern GF49 are different.
如第5A~5C圖所示,第一圖案灰階亮度GF41、第五圖案灰階亮度GF45與第九圖案灰階亮度GF49大致上相等,第二圖案灰 階亮度GF42、第六圖案灰階亮度GF46與第七圖案灰階亮度GF47大致上相等,而第三圖案灰階亮度GF43、第四圖案灰階亮度GF44與第八圖案灰階亮度GF48大致上相等。 As shown in Figures 5A to 5C, the first pattern grayscale brightness GF41, the fifth pattern grayscale brightness GF45 and the ninth pattern grayscale brightness GF49 are substantially equal, the second pattern grayscale brightness GF42, the sixth pattern grayscale brightness GF46 and the seventh pattern grayscale brightness GF47 are substantially equal, and the third pattern grayscale brightness GF43, the fourth pattern grayscale brightness GF44 and the eighth pattern grayscale brightness GF48 are substantially equal.
如第5A~5C圖所示,第一區M4與圖案區F4互補。第一區M4具有與圖案區F4類似或相同特徵。例如,第一區M4包括多個第一區塊M41。如第5A圖所示,於第一時點,此些第一區塊M41之第一者M41a、第二者M41b與第三者M41c分別是第一灰階亮度G41、第二灰階亮度G42及第三灰階亮度G43;如第5B圖所示,於第二時點,此些第一區塊M41之第一者M41a、第二者M41b與第三者M41c分別是第四灰階亮度G44、第五灰階亮度G45及第六灰階亮度G46;如第5C圖所示,於第三時點,此些第一區塊M41之第一者M41a、第二者M41b與第三者M41c分別是第七灰階亮度G47、第八灰階亮度G48及第九灰階亮度G49。在一實施例中,第一灰階亮度G41、第二灰階亮度G42與第三灰階亮度G43相異,第一灰階亮度G41、第二灰階亮度G42與第三灰階亮度G43的平均值等於背景灰階亮度GB,第四灰階亮度G44、第五灰階亮度G45與第六灰階亮度G46相異,第四灰階亮度G44、第五灰階亮度G45與第六灰階亮度G46的平均值等於背景灰階亮度GB,第七灰階亮度G47、第八灰階亮度G48與第九灰階亮度G49相異,且第七灰階亮度G47、第八灰階亮度G48與第九灰階亮度G49的平均值等於背景灰階亮度GB。 As shown in FIGS. 5A to 5C , the first region M4 complements the pattern region F4. The first region M4 has similar or identical features to the pattern region F4. For example, the first region M4 includes a plurality of first blocks M41. As shown in FIG. 5A , at a first time point, the first M41a, the second M41b and the third M41c of these first blocks M41 are respectively the first grayscale brightness G41, the second grayscale brightness G42 and the third grayscale brightness G43; as shown in FIG. 5B , at a second time point, the first M41a, the second M41b and the third M41c of these first blocks M41 are respectively the fourth grayscale brightness G44, the fifth grayscale brightness G45 and the sixth grayscale brightness G46; as shown in FIG. 5C , at a third time point, the first M41a, the second M41b and the third M41c of these first blocks M41 are respectively the seventh grayscale brightness G47, the eighth grayscale brightness G48 and the ninth grayscale brightness G49. In one embodiment, the first grayscale brightness G41, the second grayscale brightness G42 and the third grayscale brightness G43 are different, and the average value of the first grayscale brightness G41, the second grayscale brightness G42 and the third grayscale brightness G43 is equal to the background grayscale brightness GB, the fourth grayscale brightness G44, the fifth grayscale brightness G45 and the sixth grayscale brightness G46 are different, and the average value of the fourth grayscale brightness G44, the fifth grayscale brightness G45 and the sixth grayscale brightness G46 is equal to the background grayscale brightness GB, the seventh grayscale brightness G47, the eighth grayscale brightness G48 and the ninth grayscale brightness G49 are different, and the average value of the seventh grayscale brightness G47, the eighth grayscale brightness G48 and the ninth grayscale brightness G49 is equal to the background grayscale brightness GB.
如第5A~5C圖所示,第一灰階亮度G41、第四灰階亮度G44與第七灰階亮度G47相異,第二灰階亮度G42、第五灰階亮度 G45與第八灰階亮度G48相異,而第三灰階亮度G43、第六灰階亮度G46與第九灰階亮度G49相異。在另一實施例中,第一灰階亮度G41、第五灰階亮度G45與第九灰階亮度G49大致上相等,第二灰階亮度G42、第六灰階亮度G46與第七灰階亮度G47大致上相等,而第三灰階亮度G43、第四灰階亮度G44與第八灰階亮度G48大致上相等。 As shown in Figures 5A to 5C, the first grayscale brightness G41, the fourth grayscale brightness G44 and the seventh grayscale brightness G47 are different, the second grayscale brightness G42, the fifth grayscale brightness G45 and the eighth grayscale brightness G48 are different, and the third grayscale brightness G43, the sixth grayscale brightness G46 and the ninth grayscale brightness G49 are different. In another embodiment, the first grayscale brightness G41, the fifth grayscale brightness G45 and the ninth grayscale brightness G49 are substantially equal, the second grayscale brightness G42, the sixth grayscale brightness G46 and the seventh grayscale brightness G47 are substantially equal, and the third grayscale brightness G43, the fourth grayscale brightness G44 and the eighth grayscale brightness G48 are substantially equal.
如第5A~5C圖所示,沿水平方向,任相鄰二第一區塊的灰階亮度相異。相似地,沿垂直方向,任相鄰二第一區塊的灰階亮度相異。 As shown in Figures 5A to 5C, along the horizontal direction, the grayscale brightness of any two adjacent first blocks is different. Similarly, along the vertical direction, the grayscale brightness of any two adjacent first blocks is different.
如下表1所示,第5A圖之各第一區塊M41包含的像素數。表1中,「O」表示拍攝效果佳,「X」表示拍攝效果不佳,而「△」表示拍攝效果尚可接受,像素數以矩陣表示。各第一區塊M41之像素數愈多,拍攝效果愈好(拍攝到愈清楚的圖案區畫面),但閃爍值愈高。若閃爍值等於或小於19是可接受的,拍攝效果佳的像素數為10×10及20×20。 As shown in Table 1 below, the number of pixels contained in each first block M41 of Figure 5A. In Table 1, "O" indicates good shooting effect, "X" indicates poor shooting effect, and "△" indicates acceptable shooting effect. The number of pixels is represented by a matrix. The more pixels each first block M41 has, the better the shooting effect (the clearer the pattern area is captured), but the higher the flicker value. If the flicker value is equal to or less than 19, it is acceptable. The number of pixels for good shooting effect is 10×10 and 20×20.
綜上,本發明實施例提出一種顯示裝置,其可顯示一畫面,畫面包含至少一圖案區、至少一第一區及至少一第二區,其中各圖案區位於對應之第一區與第二區之間。在另一實施例中,畫面可省 略第二區。圖案區、第一區與第二區中至少一者可以是馬賽克圖案區。馬賽克圖案區包含數個區塊,其中相鄰二區塊的二灰階亮度相異,且一區塊在二時點的二灰階亮度的平均值大致上等於背景灰階亮度。如此,在視覺上,圖案區在二時點的顯示灰階與背景灰階亮度大致相等,使人眼難以辨識圖案區在二時點的灰階變化。此外,馬賽克圖案區也能降低人眼對圖案區的辨識度。 In summary, the embodiment of the present invention provides a display device, which can display a picture, the picture includes at least one pattern area, at least one first area and at least one second area, wherein each pattern area is located between the corresponding first area and second area. In another embodiment, the picture can omit the second area. At least one of the pattern area, the first area and the second area can be a mosaic pattern area. The mosaic pattern area includes a plurality of blocks, wherein the two grayscale brightness of two adjacent blocks is different, and the average value of the two grayscale brightness of a block at two time points is substantially equal to the background grayscale brightness. In this way, visually, the display grayscale of the pattern area at two time points is substantially equal to the background grayscale brightness, making it difficult for human eyes to recognize the grayscale change of the pattern area at two time points. In addition, the mosaic pattern area can also reduce the human eye's recognition of the pattern area.
依據Flicker測試(例如,Flicker@L128),本發明實施例之顯示裝置所顯示畫面的閃爍值為2.3,低於習知顯示裝置(無馬賽克設計且無內外灰階度差之設計)所顯示畫面的閃爍值4.8,也低於習知顯示裝置(無馬賽克設計)所顯示畫面的閃爍值4.7。閃爍值愈低,人眼對於圖案區(閃爍)的辨識度愈低;反之,人眼對於圖案區的辨識度愈高,人眼感受也愈不舒服。 According to the Flicker test (e.g., Flicker@L128), the flicker value of the screen displayed by the display device of the embodiment of the present invention is 2.3, which is lower than the flicker value of 4.8 of the screen displayed by the conventional display device (without mosaic design and without internal and external grayscale difference), and also lower than the flicker value of 4.7 of the screen displayed by the conventional display device (without mosaic design). The lower the flicker value, the lower the recognition of the pattern area (flicker) by the human eye; conversely, the higher the recognition of the pattern area by the human eye, the more uncomfortable the human eye feels.
由於馬賽克圖案區增加與周邊區域的對比度(灰階差),因此在攝像上,攝像器能拍攝到更清楚的圖案區外觀。在一實施例中,馬賽克圖案區之一區塊在二時點的二灰階亮度分別為較高灰階亮度及較低灰階亮,其中較高灰階亮度及較低灰階亮度依據背景灰階亮度而定。例如,透過查表、曲線或方程式,取得對應背景灰階亮度之較高灰階亮度及較低灰階亮度。 Since the mosaic pattern area increases the contrast (grayscale difference) with the surrounding area, the camera can capture a clearer appearance of the pattern area. In one embodiment, the two grayscale brightnesses of a block of the mosaic pattern area at two points in time are respectively a higher grayscale brightness and a lower grayscale brightness, wherein the higher grayscale brightness and the lower grayscale brightness are determined according to the background grayscale brightness. For example, by looking up a table, a curve or an equation, the higher grayscale brightness and the lower grayscale brightness corresponding to the background grayscale brightness are obtained.
綜上所述,雖然本揭露已以實施例揭露如上,然其並非用以限定本揭露。本揭露所屬技術領域中具有通常知識者,在不脫離本揭露之精神和範圍內,當可作各種之更動與潤飾。因此,本揭露之保護範圍當視後附之申請專利範圍所界定者為準。 In summary, although the present disclosure has been disclosed as above by the embodiments, it is not intended to limit the present disclosure. Those with ordinary knowledge in the technical field to which the present disclosure belongs can make various changes and modifications without departing from the spirit and scope of the present disclosure.
