Description
本發明係有關於OLED顯示器,尤指一種可極小化一OLED顯示器之顯示畫面的邊緣鋸齒現象的方案。The present invention relates to OLED displays, and in particular, to a solution that can minimize the jagged edge phenomenon of a display screen of an OLED display.
OLED(有機發光二極體)顯示器件具有自發光、可視角度廣、快速回應、發光效率高、發光性能受溫度影響小以及可實現柔性顯示等特點,因此,其已廣泛應用在手機和智慧穿戴等小尺寸顯示領域中。智慧穿戴OLED顯示模組的顯示幕大多為方形圓角屏或圓形屏。OLED顯示畫面係由像素組合而成,智慧穿戴OLED顯示幕上一般為real(真實) RGB像素排布,即每一個白點像素均由R、G、B三個子像素組成。請參照圖1,其為一現有顯示幕邊緣之像素排列示意圖。如圖1所示,由於顯示幕生產時像素係逐行、逐列排布,導致一顯示幕之一段圓弧邊緣10的像素交錯排列,使該段圓弧邊緣10之宏觀視效呈現邊緣鋸齒狀。另外,一般而言,各顯示器製造商對顯示幕之子像素的形狀和排布各自有獨特的設計,即使是相同尺寸的顯示幕,若是出自不同製造商的產線,顯示幕邊緣的鋸齒狀程度也會不同。OLED (organic light-emitting diode) display devices have the characteristics of self-illumination, wide viewing angle, fast response, high luminous efficiency, little influence on luminous performance by temperature, and flexible display. Therefore, it has been widely used in mobile phones and smart wearables. and other small size display areas. The displays of smart wearable OLED display modules are mostly square and rounded screens or circular screens. OLED display screens are composed of pixels. Smart wearable OLED displays generally have a real (real) RGB pixel arrangement, that is, each white point pixel is composed of three sub-pixels: R, G, and B. Please refer to Figure 1, which is a schematic diagram of the pixel arrangement at the edge of a conventional display screen. As shown in Figure 1, since the pixels are arranged row by row and column by column during the production of the display screen, the pixels on the arc edge 10 of a display screen are staggered, causing the macroscopic visual effect of the arc edge 10 to appear jagged edges. status. In addition, generally speaking, each display manufacturer has its own unique design for the shape and arrangement of sub-pixels on the display. Even displays of the same size, if they come from different manufacturers' production lines, will have different degrees of jaggedness at the edges of the display. It will also be different.
傳統的邊緣鋸齒補償演算法是以顯示幕中心為圓心,顯示幕半徑為圓半徑,畫一個完整的圓,然後調低圓周像素的亮度以弱化鋸齒顯示的目的。此種辦法僅適用於圓形屏且改善效果差。除基礎的圓形屏以外,市場對智慧穿戴顯示幕的需求還包括方形圓角屏、水滴屏、瀏海屏、上下非對稱異形屏和去中心小孔的圓形屏等多樣化設計。The traditional edge jaggedness compensation algorithm is to draw a complete circle with the center of the display screen as the center and the radius of the display screen as the radius of the circle, and then reduce the brightness of the circumferential pixels to weaken the jaggedness display. This method is only applicable to round screens and the improvement effect is poor. In addition to the basic round screen, the market demand for smart wearable displays also includes a variety of designs such as square rounded corner screens, water drop screens, sea-view screens, top and bottom asymmetric special-shaped screens, and round screens without center holes.

請參照圖3,其為本發明應用在一圓形顯示幕的示意圖。如圖3所示,本發明係在一圓形顯示幕20中設定一虛擬圓21,虛擬圓21之半徑為(Rx, Ry),且其圓心位置為(Ox, Oy),從而產生4段弧形邊界顯示區,各段弧形邊界顯示區的寬度為W,以W=2為例,表示寬度為2個像素。另外,較佳地,在各段弧形邊界顯示區中,其遞減分布的設置方式可為:設定較靠近圓心位置(Ox, Oy)的像素的灰階值為顯示區域像素的60%~80%,而離圓心位置(Ox, Oy)較遠的像素的灰階值為顯示區域像素的20%~40%。另外,本發明可根據該圓形顯示幕20的實際顯示效果調整該遞減分布的設置方式以極小化圓形顯示幕20的邊界鋸齒現象。依此方式,本發明亦可應用在Rx > Ry或Rx < Ry之橢圓顯示幕中。Please refer to FIG. 3 , which is a schematic diagram of the present invention applied to a circular display screen. As shown in Figure 3, the present invention sets a
另外,圓形顯示幕的拓展需求之一是使傳統錶盤指針與智慧穿戴顯示幕相結合,其係在圓形顯示幕的中心挖孔並且在整機結構上預留實體指針的位置。在此應用情境中,本發明會在該圓形顯示幕的中心設定第二個圓,依該第二個圓在一幀顯示資料中對應設置一圓形全黑區,並使該圓形全黑區內之顯示資料的灰階值均為0。另外,本發明亦可在緊接該圓形全黑區之外圍設置一環狀顯示區,並使該環狀顯示區內之顯示資料的灰階值均為一遞增分布,而該遞增分布的方向係由該環狀顯示區中鄰近該圓形全黑區的區域指向遠離該圓形全黑區的區域。In addition, one of the expansion needs of circular displays is to combine traditional dial pointers with smart wearable displays, which dig holes in the center of the circular display and reserve the position of physical pointers on the entire structure. In this application scenario, the present invention sets a second circle in the center of the circular display screen, sets a circular full black area corresponding to the second circle in one frame of display data, and makes the circle completely black. The gray scale value of the displayed data in the black area is 0. In addition, the present invention can also set up an annular display area immediately outside the circular black area, so that the grayscale values of the display data in the annular display area are all in an increasing distribution, and the increasing distribution The direction is from the area adjacent to the circular full black area in the annular display area to the area away from the circular full black area.

By configuring the center and radius of the second circle, make the second circle coincide with the camera position. In this application scenario, the present invention will set a circular full black area corresponding to the second circle in one frame of display data, and make the grayscale values of the display data in the circular full black area equal to 0. In addition, the present invention can also set up an annular display area immediately outside the circular black area, so that the grayscale values of the display data in the annular display area are all in an increasing distribution, and the increasing distribution The direction is from the area adjacent to the circular full black area in the annular display area to the area away from the circular full black area.
另外,針對方形圓角顯示幕而言,其在直邊的像素平整排列,但是由於其在四個R角位置的像素係成交錯排列,因此其在四個R角處的邊緣鋸齒現象會很明顯。請參照圖4,其為本發明應用在一方形圓角顯示幕的示意圖。如圖4所示,在一方形圓角顯示幕30中,其具有四段圓弧邊緣31及四個直邊32,依此,本發明會將一幀顯示資料分成一主要顯示區及四個邊緣全黑區,以及使四個邊緣全黑區內之顯示資料的灰階值均為0。另外,本發明亦可在該主要顯示區中鄰近四段圓弧邊緣31處各對應設置一段弧形邊界顯示區,並使各段所述弧形邊界顯示區內之顯示資料的灰階值均為一遞減分布,其中,各該遞減分布的方向係由各段所述弧形邊界顯示區中鄰近該主要顯示區的區域指向遠離該主要顯示區的區域。另外,對於顯示幕應用而言,可顯示區域應當越大越好,而各段所述弧形邊界顯示區應儘量縮小,因此,較佳地,各段所述弧形邊界顯示區的寬度為兩個像素。In addition, for a square display with rounded corners, the pixels on the straight edges are arranged evenly, but since the pixels at the four R corners are arranged in a staggered manner, the jagged edges at the four R corners will be very obvious. Please refer to FIG. 4, which is a schematic diagram of the application of the present invention to a square display with rounded corners. As shown in FIG. 4, in a square display with
