Description
本揭露是關於一種無機發光二極體顯示器,特別是關於一種無機發光二極體顯示器之子像素排列結構。The present disclosure relates to an inorganic light emitting diode display, and more particularly to a sub-pixel arrangement structure of an inorganic light emitting diode display.
隨著顯示技術的蓬勃發展,目前市場對於顯示面板的性能要求是朝向高解析度、高亮度與低耗電等方向邁進。然而,隨著顯示面板的解析度增加,為了顯示高解析度,顯示面板的子像素的數目也會隨之增加,從而增加顯示面板的製作成本。為了降低顯示面板的製作成本,提升影像品質,可以藉由顯示裝置使用特殊的子像素排列,配合演算法,以提高顯示面板的色彩解析度。With the rapid development of display technology, the current market demand for display panel performance is moving towards high resolution, high brightness and low power consumption. However, as the resolution of display panels increases, in order to display high resolution, the number of sub-pixels of the display panel will also increase, thereby increasing the manufacturing cost of the display panel. In order to reduce the manufacturing cost of the display panel and improve the image quality, the display device can use a special sub-pixel arrangement and an algorithm to improve the color resolution of the display panel.
相較於傳統顯示器的RGB條狀(RGB Stripe)排列,菱形排列形式的子像素排列在有機發光二極體(OLED)顯示應用被廣泛地討論,透過增加紅色子像素以及藍色子像素的面積、降低電流密度,以延長紅藍兩色因材料特性的壽命問題,並延展紅藍兩色發光面積。然而由於發光面積限制了電流密度,導致無法以更高的電流補償紅藍兩色亮度,也降低了子像素排列的多樣性。此外由於傳統液晶顯示器(LCD)或有機發光二極體(OLED)具有較大的開口率,增加顯示器檢修的困難。因此,需要改進顯示裝置,以使顯示裝置具有更大的電流密度工作範圍、更大的子像素排列的多樣性、較低的開口率等性質,以進一步提高色彩解析度,提升影像品質,降低檢修的困難。Compared to the RGB stripe arrangement of traditional displays, the diamond arrangement of sub-pixels in the organic light-emitting diode (OLED) display application has been widely discussed. By increasing the area of red and blue sub-pixels and reducing the current density, the life of red and blue due to material characteristics can be extended, and the luminous area of red and blue can be extended. However, since the luminous area limits the current density, it is impossible to compensate for the brightness of red and blue with a higher current, and the diversity of sub-pixel arrangement is also reduced. In addition, since traditional liquid crystal displays (LCD) or organic light-emitting diodes (OLED) have a larger opening rate, it is more difficult to repair the display. Therefore, it is necessary to improve the display device so that the display device has properties such as a larger current density operating range, a greater diversity of sub-pixel arrangements, and a lower aperture ratio, so as to further improve color resolution, enhance image quality, and reduce the difficulty of maintenance.
根據本揭露的一些實施例,提供一種無機發光二極體(LED)顯示器,包括:第一子單元及第二子單元,第一子單元包括四個第一晶片,四個第一晶片排列成第一矩形,且位於第一矩形的四個角落,第二子單元包括四個第二晶片,四個第二晶片排列成第二矩形,且位於第二矩形的四個角落,其中,第一矩形與第二矩形彼此重交疊並形成一重疊區,且於水平方向、垂直方向或其二者中,四個第一晶片中任兩相鄰者之間不存在任何發光二極體晶片。According to some embodiments of the present disclosure, an inorganic light emitting diode (LED) display is provided, comprising: a first sub-unit and a second sub-unit, the first sub-unit comprising four first chips, the four first chips are arranged into a first rectangle and are located at the four corners of the first rectangle, the second sub-unit comprising four second chips, the four second chips are arranged into a second rectangle and are located at the four corners of the second rectangle, wherein the first rectangle and the second rectangle overlap each other and form an overlapping area, and in the horizontal direction, the vertical direction or both, there is no light emitting diode chip between any two adjacent ones of the four first chips.
以下說明本揭露實施例之發光裝置及其形成方法。然而,應能理解本揭露實施例提供許多合適的發明概念而可實施於廣泛的各種特定背景。所揭示的特定實施例僅用於說明以特定方法製作及使用本發明,而並非用以侷限本發明的範圍。再者,在本揭露實施例之圖式及說明內容中係使用相同的標號來表示相同或相似的部件。The following describes the light emitting device and its forming method of the disclosed embodiment. However, it should be understood that the disclosed embodiment provides many suitable inventive concepts and can be implemented in a wide variety of specific contexts. The disclosed specific embodiment is only used to illustrate the manufacture and use of the invention in a specific method, and is not used to limit the scope of the invention. Furthermore, the same reference numerals are used in the drawings and descriptions of the disclosed embodiment to represent the same or similar components.
說明書中所述及之「約」、「大約」、「大抵」等用語通常表示在一給定值或範圍的20%之內,較佳是10%之內,且更佳是5%之內,或3%之內,或2%之內,或1%之內,或0.5%之內。應注意的是,說明書中所提供的數量為大約的數量,亦即在沒有特定說明「約」、「大約」、「大抵」的情況下,仍可隱含「約」、「大約」、「大抵」之含義。The terms "about", "approximately", "generally" and the like mentioned in the specification generally mean within 20% of a given value or range, preferably within 10%, and more preferably within 5%, or within 3%, or within 2%, or within 1%, or within 0.5%. It should be noted that the quantities provided in the specification are approximate quantities, that is, in the absence of specific description of "about", "approximately", "generally", the meaning of "about", "approximately", "generally" can still be implied.
根據本揭露的一些實施例,無機發光二極體顯示器包括紅色無機發光二極體晶片(以下簡稱紅色晶片)、藍色無機發光二極體晶片(以下簡稱藍色晶片)、以及數量最多的綠色無機發光二極體晶片(以下簡稱綠色晶片)。本揭露實施例的特徵之一在於綠色晶片的數量分別大於紅色晶片的數量、藍色晶片的數量。現有顯示器所使用的子像素(子像素是指顯示影像的最小單位,例如綠色晶片)一般利用RGB條狀(RGB Stripe)排列,使用相同數量的RGB晶片,以構成一完整像素。然而,本揭露實施例所提供的顯示器中,透過增加綠色晶片的數量,並且調整不同顏色晶片間的最小間距,不但可以進一步提高解析度,也可以提升影像品質。According to some embodiments of the present disclosure, an inorganic light emitting diode display includes a red inorganic light emitting diode chip (hereinafter referred to as red chip), a blue inorganic light emitting diode chip (hereinafter referred to as blue chip), and a green inorganic light emitting diode chip (hereinafter referred to as green chip) with the largest number. One of the characteristics of the embodiments of the present disclosure is that the number of green chips is greater than the number of red chips and the number of blue chips, respectively. The sub-pixels used in existing displays (sub-pixels refer to the smallest unit for displaying an image, such as green chips) are generally arranged in RGB stripes, using the same number of RGB chips to form a complete pixel. However, in the display provided by the embodiments of the present disclosure, by increasing the number of green chips and adjusting the minimum distance between chips of different colors, not only the resolution can be further improved, but also the image quality can be improved.
第1圖繪示出本揭露實施例,無機發光二極體顯示器10的剖面示意圖。在第1圖中,無機發光二極體顯示器10包括基板100與多個發光二極體晶片102以二維陣列的形式間隔排佈在基板100上。為簡化圖式,圖中僅繪示出三個發光二極體晶片102,但本揭露不以此為限。每個發光二極體晶片102各自具有第一電極110a(例如正極)與第二電極110b(例如負極)。在一些實施例中,可以根據不同類型的發光二極體晶片102設置第一電極110a與第二電極110b的極性,舉例來說,在一些實施例中,第一電極110a可以為負極,第二電極110b可以為正極。第一電極110a與第二電極110b設置在發光二極體晶片102靠近基板100的同一側(可以稱為背側),舉例來說,在一些實施例中,發光二極體晶片102遠離基板100的一側為出光側(可以稱為前側),第一電極110a與第二電極110b設置在發光二極體晶片102出光側的相反側。在一些實施例中,基板100可以為印刷電路板(printed circuit board, PCB)、薄膜電晶體玻璃(thin film transistor glass, TFT glass) 、互補式金氧半導體(complementary metal oxide semiconductor, CMOS)基板或其他合適的材料,但不限於此。發光二極體晶片102包括綠色晶片102g、紅光晶片102r、以及藍色晶片102b。在一些實施例中,發光二極體晶片102的材料可以包括無機半導體材料,例如III-V族化合物、II-VI族化合物、或其他合適的材料,但不限於此。在一些實施例中,III-V族化合物可為氮化鎵基(GaN-based)材料、砷化鎵基(GaAs-based)材料、或磷化砷基(InP-based)材料,II-VI族化合物可為硫化鋅基(ZnS-based)材料或硒化鎘基(CdSe-based)材料。FIG. 1 shows a cross-sectional schematic diagram of an inorganic light
在一些實施例中,第一電極110a與第二電極110b的材料可以包括金屬或金屬合金。舉例而言,第一電極110a與第二電極110b金屬材料可以包括:銅(Cu)、鋁(Al)、銦(In)、錫(Sn)、金(Au)、鉑(Pt)、鋅(Zn)、銀(Ag)、鈦(Ti)、鎳(Ni)或其組合,但不限於此。In some embodiments, the material of the
第2圖是繪示出第1圖的無機發光二極體顯示器10的子像素排列結構示意圖。在第2圖中,在基板100上設置有周期性排列的綠色晶片102g、紅色晶片102r、以及藍色晶片102b。在一些實施例中,發光二極體晶片102沿著第一方向D1以及垂直於第一方向D1的第二方向D2延伸排列,如第2圖所示。因為人眼對於綠色波長較為敏感,縮小綠色間距能夠有效地使人眼看到更密集的子像素資訊,因此在第一方向D1上,設置相鄰兩綠色晶片102g的最小間距P
sub_g小於相鄰兩紅色晶片102r的最小間距P
sub_r,且相鄰兩綠色晶片102g的最小間距P
sub_g小於相鄰兩藍色晶片102b的最小間距P
sub_b。上述子像素的排列結構可以提高色彩解析度,以更少的晶片數量提供較佳的影像品質,降低成本。

由於人眼對於彩色影像的感受主要由借色機制與視覺極限機制所主導,因此可以藉由調整相鄰晶片的最小間距,達到借色與混光的效果。舉例來說,為了同時滿足借色機制:
與視覺極限機制:
的情況下,可以調整相鄰顏色晶片的最小間距滿足以下關係式:
以達到提高色彩解析度,以及較佳的影像品質。上述CPD(cycles per degree)為空間頻率的單位,空間頻率定義為人眼視野內能夠辨識出每度視角內的黑白條紋周期數,與條紋間距以及人眼與顯示器的距離有關,舉例來說,當條紋間距為P,人眼與顯示器的距離為D時,可以定義角度頻率f如下:
。
當角度頻率f(P)在15CPD~30CPD之間,可以達到借色機制,明確而言,為了使顯示器上的紅色晶片102r和藍色晶片102b可以分別借色給周圍的綠色晶片102g,可以調整相鄰兩紅色晶片102r的最小間距P
sub_r以及相鄰兩藍色晶片102b的最小間距P
sub_b在15CPD ~ 30CPD之間。在一些實施例中,只考慮紅色晶片102r和藍色晶片102b之中最小的角度頻率
在15CPD ~ 30CPD之間。當角度頻率f(P)在30CPD~60CPD之間,可以達到視覺極限機制,明確而言,為了使顯示器上的紅色晶片102r、藍色晶片102b、以及綠色晶片102g達到混光的效果,可以調整相鄰兩紅色晶片102r的最小間距P
sub_r、相鄰兩藍色晶片102b的最小間距P
sub_b、以及相鄰兩綠色晶片102g的最小間距P
sub_g在30CPD ~ 60CPD之間。在一些實施例中,由於在第一方向D1上,相鄰兩綠色晶片102g的最小間距P
sub_g最小,所以只考慮綠色晶片102g的角度頻率f(P
sub_g)在30CPD ~ 60CPD之間。
Since the human eye's perception of color images is mainly dominated by the color borrowing mechanism and the visual limit mechanism, the effects of color borrowing and light mixing can be achieved by adjusting the minimum distance between adjacent chips. For example, in order to satisfy the color borrowing mechanism at the same time: And the visual limit mechanism: In this case, the minimum spacing between adjacent color chips can be adjusted to satisfy the following relationship: In order to achieve improved color resolution and better image quality. The above CPD (cycles per degree) is the unit of spatial frequency. Spatial frequency is defined as the number of black and white stripe cycles that can be identified within the human eye field of vision per degree of viewing angle. It is related to the stripe spacing and the distance between the human eye and the display. For example, when the stripe spacing is P and the distance between the human eye and the display is D, the angular frequency f can be defined as follows: When the angular frequency f(P) is between 15CPD and 30CPD, the color borrowing mechanism can be achieved. Specifically, in order to allow the
繼續參照第2圖,在一些實施例中,多個綠色晶片102g、至少一個紅色晶片102r以及至少一個藍色晶片102b共同構成最小重複單元(one point unit)104。上述最小重複單元104為矩形,重複地二維排列構成無機發光二極體顯示器10。特別注意的是,在其他實施例中,最小重複單元104可以為矩形、三角形、多邊形、圓形等型態,但本揭露不以此為限。在每個最小重複單元104中,綠色晶片102g的數量最多,亦即綠色晶片102g的數量G大於紅色晶片102r的數量R,且綠色晶片102g的數量G大於藍色晶片102b的數量B。在一些實施例中,最小重複單元104中紅色晶片102r的數量R大於藍色晶片102b的數量B。在一些實施例中,最小重複單元104中紅色晶片102r的數量R與藍色晶片102b的數量B相同。由於最小重複單元104中發光二極體晶片102各種顏色晶片的比例不再是1:1:1(RGB),與傳統晶片排列的方式不同,因此在應用上,預先透過演算法,根據晶片比例進行影像重新計算,最後再根據計算完的結果,將影像資訊傳給最小重複單元104內的發光二極體晶片102,以顯示完整的影像。在一些實施例中,演算法可以採用常見的子像素渲染技術。Continuing to refer to FIG. 2, in some embodiments, a plurality of
繼續參照第2圖,在一些實施例中,最小重複單元104內的每個發光二極體晶片102具有大致上相同的尺寸,舉例來說,不同顏色的發光二極體晶片102具有大致上相同的俯視面積。在一些實施例中,最小重複單元104具有單元面積S
p,且每個綠色晶片102g、紅色晶片102r、藍色晶片102b分別具有發光面積S
g、S
r、S
b。在一些實施例中,不同顏色晶片的發光面積相同,舉例來說,S
g=S
r=S
b,因此,相較於傳統藉由不同子像素尺寸以達到顯示功能的OLED,毋須額外因應有機發光體發光效率不同而另外調整不同的電流密度,使得各色子像素壽命相當,降低設計困難。
Continuing with reference to FIG. 2 , in some embodiments, each
在一些實施例中,無機發光二極體顯示器10的開口率(aperture ratio)A<30%,如第2圖所示。開口率A定義為發光二極體晶片102的總發光面積於最小重複單元104內的占比,滿足以下關係式:
其中,G、R、B分別為最小重複單元104內的綠色晶片102g的數量、紅色晶片102r的數量、藍色晶片102b的數量。相較於傳統液晶顯示器(LCD)或是有機發光二極體(OLED)的開口率設計在30%至90%,本揭露能夠提供更低的開口率,利於無機發光二極體顯示器10中發光二極體晶片102的檢修。
In some embodiments, the aperture ratio A of the
第3A至3B圖是根據本揭露的各種實施例,繪示出最小重複單元104內的發光二極體晶片102的排列示意圖。參照第3A圖,在一些實施例中,最小重複單元104包括多個子單元106,舉例來說,第一子單元106a以及第二子單元106b。第一子單元106a(虛線方框)由部份的綠色晶片102g所構成,且第二子單元106b(點線方框)由剩餘的綠色晶片102g以及紅色晶片102r和藍色晶片102b所構成。特別注意的是,子單元106涵蓋最小重複單元104的俯視形狀幾何中心C1,如第3A圖所示。FIGS. 3A to 3B are schematic diagrams showing the arrangement of the
在一些實施例中,第一子單元106a(虛線)的俯視形狀幾何中心C2可以與第二子單元106b(點線)的晶片102錯位(意指不重疊),如第3A圖所示。在一些實施例中,第二子單元106b的俯視形狀幾何中心C3可以與第一子單元106a的晶片102錯位。在另一些實施例中,第一子單元106a的俯視形狀幾何中心C2可以與第二子單元106b的晶片102重疊,且第二子單元106b的俯視形狀幾何中心C3可以與第一子單元的晶片102重疊,如第3B圖所示。此時,6個綠色晶片102g構成五角形的第一子單元106a(虛線),1個紅色晶片以及1個藍色晶片構成長方形的第二子單元106 b(點線)。在這個情況下,,以整個顯示器而言,紅色晶片102r和藍色晶片102b均勻地分布在數量較多的綠色晶片102g的周圍。相對於第3A圖第一子單元106a的俯視形狀幾何中心C2與第二子單元106b的晶片102有錯位的情況,在第3B圖中,第一子單元106a的俯視形狀幾何中心C2與第二子單元106b中的晶片102重疊,且第二子單元106b的俯視形狀幾何中心C3與第一子單元106a中的晶片102重疊,,因此紅色晶片102r和藍色晶片102b能夠更均勻地借色給周圍的綠色晶片102g,進而提高影像解析度及品質。特別注意的是,第一子單元106a與第二子單元106b具有交疊的區域,上述交疊的區域包括第一子單元106a的俯視形狀幾何中心C2,因此除了可以提高解析度外,也可以提升影像品質。In some embodiments, the top-view shape geometric center C2 of the first sub-unit 106a (dashed line) may be misaligned (meaning not overlapped) with the
參照第4A-4B圖,根據本揭露的各種實施例,繪示出在最小重複單元104內,紅綠藍色晶片數量(RGB)的比例為1:2:1的實施例。首先參照第4A圖,在一些實施例中,最小重複單元104包括2個綠色晶片、1個紅色晶片和1個藍色晶片。2個綠色晶片排列構成矩形的第一子單元106a(虛線),1個紅色晶片和1個藍色晶片排列構成矩形的第二子單元106b(點線),第一子單元106a和第二子單元106b具有交疊的區域,交疊的區域包括第一子單元106a的俯視形狀幾何中心C1。如第4A圖所示,在此實施例中,由於每個紅色晶片與周圍相鄰的紅色晶片具有相同的距離(L1=L2),因此紅色晶片102r能夠均勻地借色給周圍的綠色晶片102g,除了提高色彩解析度外,同時等比例地增加第一方向上D1與第二方向上D2的影像品質。Referring to FIGS. 4A-4B , according to various embodiments of the present disclosure, an embodiment in which the ratio of the number of red, green and blue chips (RGB) is 1:2:1 in the
參照第4B圖,在一些實施例中,最小重複單元104包括4個綠色晶片、2個紅色晶片和2個藍色晶片。由於4個綠色晶片排列構成平行四邊形的第一子單元106a(虛線),2個紅色晶片和2個藍色晶片排列構成平行四邊形的第二子單元106b(點線),且每個紅色晶片與周圍相鄰的紅色晶片具有不同的距離(L1’≠L2’),由於在第一方向D1與第二方向上D2的距離落差,影像品質在兩方向的效果強弱不等比例,搭配演算法的計算,更能夠凸顯在單一方向的影像品質,同時也能提高色彩解析度。Referring to FIG. 4B , in some embodiments, the
參照第5圖,根據本揭露的各種實施例,繪示出在最小重複單元104內,紅綠藍色晶片數量(RGB)的比例為1:3:1的實施例。在一些實施例中,最小重複單元104包括3個綠色晶片、1個紅色晶片和1個藍色晶片。3個綠色晶片排列構成三角形的第一子單元106a(虛線),1個紅色晶片和1個藍色晶片排列構成長方形的第二子單元106b(點線)。如第5圖所示,第一子單元106a和第二子單元106b具有交疊的區域,由於交疊的區域包括第一子單元106a的俯視形狀幾何中心C2,使得第一子單元106a和第二子單元106b大致分布在最小重複單元104的俯視形狀幾何中心C1周圍,紅色晶片102r和藍色晶片102b能夠均勻地借色給周圍的綠色晶片102g,因此,能夠在提高色彩解析度的同時,增加影像品質。Referring to FIG. 5 , according to various embodiments of the present disclosure, an embodiment is shown in which the ratio of the number of red, green, and blue chips (RGB) in the
在一些實施例中,最小重複單元104彼此可以不緊鄰,以行列方式交錯設置在無機發光二極體顯示器10中。藉由調整最小重複單元104間的間距,使得相鄰綠色晶片102g於第一方向上的最小間距P
sub_g大致相同,可以提高色彩解析度,增加影像品質。
In some embodiments, the
參照第6A-6C圖,根據本揭露的各種實施例,繪示出在最小重複單元104內,紅綠藍色晶片數量(RGB)的比例為1:4:1的實施例。首先參照第6A圖,在一些實施例中,最小重複單元104為箏形,以行列方式交錯構成無機發光二極體顯示器10,最小重複單元104包括4個綠色晶片、1個紅色晶片和1個藍色晶片。4個綠色晶片排列構成菱形的第一子單元106a(虛線),1個紅色晶片和1個藍色晶片排列構成長方形的第二子單元106b(點線)。如第6A圖所示,第一子單元106a和第二子單元106b具有交疊的區域,由於交疊的區域包括第一子單元106a的俯視形狀幾何中心C2,使得第一子單元106a和第二子單元106b大致分布在最小重複單元104的俯視形狀幾何中心C1周圍,紅色晶片102r和藍色晶片102b能夠均勻地借色給周圍的綠色晶片102g,因此能夠同時改善色彩解析度及影像品質。Referring to FIGS. 6A-6C , according to various embodiments of the present disclosure, an embodiment in which the ratio of the number of red, green and blue chips (RGB) in the
參照第6B圖,在一些實施例中,最小重複單元104包括8個綠色晶片、2個紅色晶片和2個藍色晶片。4個綠色晶片排列構成矩形的第一子單元106a(虛線),2個紅色晶片和2個藍色晶片排列構成矩形的第二子單元106b(點線),剩餘4個綠色晶片排列構成矩形的第三子單元106c(點虛線),且上述子單元(106a,106b,106c)彼此局部交疊。6B , in some embodiments, the
參照第6C圖,在一些實施例中,最小重複單元104包括4個綠色晶片、1個紅色晶片和1個藍色晶片。4個綠色晶片排列構成矩形的第一子單元106a,1個紅色晶片和1個藍色晶片排列構成長方形的第二子單元106b,第一子單元106a和第二子單元106b大致分布在最小重複單元104的俯視形狀幾何中心C1周圍,如第6C圖所示。值得注意的是,最小重複單元104彼此緊鄰且以行列方式交錯設置在無機發光二極體顯示器10中。Referring to FIG. 6C , in some embodiments, the
參照第7A-7C圖,根據電腦模擬出本揭露的實施例與傳統顯示器因晶片排列方式不同所導致的影像品質差異。第7A和7C圖為電腦模擬子像素由傳統RGB條狀(RGB stripe)排列形成的影像,差異在於第7C圖的影像解析度為第7A圖的2倍,此差異來自於第7C圖使用的晶片(子像素)數量為第7A圖使用的晶片(子像素)數量的2倍。第7B圖為根據本揭露的一些實施例,以電腦模擬子像素由紅綠藍色晶片數量(RGB)的比例為1:2:1(如第4A圖的實施例)所形成的影像。從第7B圖與第7A圖比較,可明顯看出,第7B圖的解析度高於第7A圖。本揭露第7B圖的實施例藉由僅在最小重複單元104中多設置一個綠色晶片,就能夠將解析度提升至相當於需使用2倍數量晶片(子像素)的傳統RGB條狀(RGB stripe)排列的解析度(如第7C圖),並且更進一步地提升影像品質。Referring to Figures 7A-7C, the difference in image quality due to the different chip arrangements between the embodiments of the present disclosure and the traditional display is simulated by computer. Figures 7A and 7C are computer simulated images formed by sub-pixels arranged in a traditional RGB stripe. The difference is that the image resolution of Figure 7C is twice that of Figure 7A. This difference comes from the fact that the number of chips (sub-pixels) used in Figure 7C is twice the number of chips (sub-pixels) used in Figure 7A. Figure 7B is a computer simulated image formed by sub-pixels with a ratio of red, green, and blue chips (RGB) of 1:2:1 (such as the embodiment of Figure 4A) according to some embodiments of the present disclosure. Comparing Figure 7B with Figure 7A, it can be clearly seen that the resolution of Figure 7B is higher than that of Figure 7A. The embodiment of FIG. 7B of the present disclosure can increase the resolution to a level equivalent to that of a conventional RGB stripe arrangement (as shown in FIG. 7C ) that requires twice the number of chips (sub-pixels) by only providing one more green chip in the
應該注意的是,本揭露概括地描述無機發光二極體顯示器之子像素排列結構。可以使用其他子像素排列結構。舉例來說,可以使用不同類型的無機發光二極體晶片,可以使用不同發光面積的無機發光二極體晶片,可以使用更少或額外的綠色晶片、紅色晶片、藍色晶片,可以根據設計的需求,調整綠色晶片間的最小間距與紅色或藍色晶片間的最小間距的關係,形成無機發光二極體顯示器。It should be noted that the present disclosure generally describes the sub-pixel arrangement structure of the inorganic light emitting diode display. Other sub-pixel arrangement structures can be used. For example, different types of inorganic light emitting diode chips can be used, inorganic light emitting diode chips with different light emitting areas can be used, fewer or additional green chips, red chips, and blue chips can be used, and the relationship between the minimum spacing between green chips and the minimum spacing between red or blue chips can be adjusted according to design requirements to form an inorganic light emitting diode display.
應理解的是,本發明的範圍並不限於上述技術特徵的特定組合而成的技術方案,同時也應涵蓋由上述技術特徵或其等同特徵進行任意組合而形成的其它技術方案。上述各實施例可以任意組合形成新的實施例,所有組合形成的新實施例均在本發明的保護範圍內。It should be understood that the scope of the present invention is not limited to the technical solutions formed by the specific combination of the above technical features, but also covers other technical solutions formed by any combination of the above technical features or their equivalent features. The above embodiments can be combined arbitrarily to form new embodiments, and all new embodiments formed by the combination are within the protection scope of the present invention.
本揭露的顯示器子像素的排列可以根據顯示器的設計需求,利用人眼對於綠光波段更為敏感的特性,在顯示器中設置最多數量的綠色晶片,提高顯示器的影像解析度與影像品質。舉例來說,可以在顯示器上劃分以行列平行及/或交錯排列的最小重複單元,接著,在每個最小重複單元內設置紅色晶片、藍色晶片以及綠色晶片,綠色晶片的總數量分別大於紅色晶片的總數量及藍色晶片的總數量。最小重複單元內晶片的排列方式可以將數量最多的綠色晶片大致平均散佈在最小重複單元內,並將紅色晶片以及藍色晶片大致散佈在顯示器中綠色晶片的附近。舉例來說,最小重複單元可以包括多個子單元,子單元大致分為兩類,第一類子單元以及第二類子單元。第一類子單元至少包括兩個單一顏色晶片,例如兩個綠色晶片,或更多個綠色晶片,但不以此為限。在一些實施例中,第一類子單元可以有多個,例如兩個或兩個以上的第一類子單元。第二類子單元至少包括兩個異色晶片,例如一個紅色晶片和一個藍色晶片,在一些實施例中,第二類子單元可以包括綠色晶片,例如一個紅色晶片、一個藍色晶片、和兩個綠色晶片。藉由在顯示器設置數量最多的綠色晶片,並且調整綠色晶片間的最小間距,可以同時提高影像解析度及影像品質,此外還可以減少晶片使用,進而降低成本。The arrangement of the sub-pixels of the display disclosed in the present invention can be based on the design requirements of the display, using the characteristic that the human eye is more sensitive to the green light band, and the maximum number of green chips can be set in the display to improve the image resolution and image quality of the display. For example, the display can be divided into minimum repeating units arranged in parallel and/or staggered rows and columns, and then red chips, blue chips and green chips are set in each minimum repeating unit, and the total number of green chips is greater than the total number of red chips and the total number of blue chips. The arrangement of chips in the minimum repeating unit can distribute the largest number of green chips roughly evenly in the minimum repeating unit, and distribute the red chips and blue chips roughly near the green chips in the display. For example, the minimum repeating unit can include multiple sub-units, and the sub-units are roughly divided into two categories, first-category sub-units and second-category sub-units. The first type of sub-unit includes at least two single-color chips, such as two green chips, or more green chips, but not limited thereto. In some embodiments, there may be multiple first type of sub-units, such as two or more first type of sub-units. The second type of sub-unit includes at least two heterochromatic chips, such as one red chip and one blue chip. In some embodiments, the second type of sub-unit may include green chips, such as one red chip, one blue chip, and two green chips. By setting the largest number of green chips in the display and adjusting the minimum spacing between the green chips, the image resolution and image quality can be improved at the same time, and the use of chips can be reduced, thereby reducing costs.
