Description
本發明涉及顯示技術領域,尤其涉及一種像素陣列、包含該像素陣列的顯示器以及用於將圖像呈現在顯示器上的方法。 The present invention relates to the field of display technologies, and in particular, to a pixel array, a display including the pixel array, and a method for presenting an image on a display.
主動矩陣有機發光二極體(以下簡稱AMOLED)是新一代的顯示器。圖1(a)至圖1(e)為現有技術中AMOLED顯示器的各種像素陣列的示意圖。 The active matrix organic light emitting diode (hereinafter referred to as AMOLED) is a new generation of display. 1(a) to 1(e) are schematic views of various pixel arrays of an AMOLED display in the prior art.
傳統的像素陣列的像素單元是由紅綠藍三個子像素組成的。但現行AMOLED的像素陣列設計都趨向使用類似PenTile技術的排列方式。PenTile像素陣列的單個像素點(或稱像素單元)是不一樣的,一種是紅綠,一種是藍綠。我們知道只有三基色才能構成所有的顏色,而兩種顏色是不可以構成所有顏色的,所以在實際顯示圖像時,PenTile的一個像素單元會“借,’用與其相鄰的像素單元的另一種顏色來構成三基色。水平方向,每個像素單元和相鄰的像素單元共用自己所不具備的那種顏色的子像素,共同達到白色顯示的效果。 The pixel unit of a conventional pixel array is composed of three sub-pixels of red, green and blue. However, current AMOLED pixel array designs tend to use an arrangement similar to PenTile technology. The individual pixel points (or pixel units) of a PenTile pixel array are different, one is red-green and the other is blue-green. We know that only three primary colors can form all the colors, and the two colors cannot constitute all the colors, so when actually displaying the image, one pixel unit of PenTile will "borrow," use another pixel unit adjacent to it. One color constitutes three primary colors. In the horizontal direction, each pixel unit and adjacent pixel units share sub-pixels of a color that they do not have, and collectively achieve the effect of white display.
因為目前AMOLED在高解析度的產品上遇到了瓶頸,因為目前主流AMOLED蒸鍍技術為FMM(Fine Metal Mask),其蒸鍍精度在正常的像素陣列方式(帶狀排列,stripe)時超過200PPI的產品就容易有混色的問題(即良率低的問題)。 Because AMOLED currently encounters a bottleneck in high-resolution products, because the current mainstream AMOLED evaporation technology is FMM (Fine Metal Mask), its evaporation accuracy exceeds 200 PPI in the normal pixel array mode (stripe). The product is prone to mixed color problems (ie, low yield).
於是衍生出非典型PenTile像素陣列等的渲染(rendering)像素陣列方式,可以節省1/3的子像素數量,藉以解決FMM蒸鍍精度不足的問題。但是PenTile排列畢竟與真實RGB子像素不同,由於共用子像素的關係,會使畫面在不連續的地方的邊界顯得有些模糊感。然而,PenTile或是非典型PenTile的像素陣列方式也會導致畫面邊緣粗糙的問題。 Therefore, a rendering pixel array method such as an atypical PenTile pixel array is derived, which can save 1/3 of the number of sub-pixels, thereby solving the problem of insufficient FMM evaporation precision. However, the PenTile arrangement is different from the real RGB sub-pixels. Because of the shared sub-pixel relationship, the boundary of the picture in a discontinuous place is somewhat blurred. However, the pixel array method of PenTile or atypical PenTile also causes the problem of rough edges.
因此,本發明提供了一種新的像素陣列、包含該像素陣列的顯示器、以及將圖像呈現於顯示器上的方法。本發明既能節省子像素,又能克服現有技術的像素陣列存在的畫面邊緣模糊不清的缺陷,同時提高蒸鍍精度、蒸鍍良率以及圖像解析度。 Accordingly, the present invention provides a new pixel array, a display including the pixel array, and a method of presenting an image on a display. The invention can not only save the sub-pixels, but also overcome the defects of the blurred edges of the screens existing in the pixel array of the prior art, and at the same time improve the vapor deposition precision, the evaporation yield and the image resolution.

To display various styles in an image. Each of the first brightness value, the second brightness value, and the third brightness value is a ratio of a grayscale value (brightness) of a respective color to its maximum grayscale value, and is expressed as a percentage ranging from 0% to 100%. For example: for a color n-bit grayscale value, the grayscale uses a value from 0 representing no such color to (2 n -1) representing a full color. The former has a brightness value of 0% and the latter has a brightness value of 100% of this color. The luminance value may be based on an 8-color bit grayscale value, ie, the grayscale value takes values from 0, 1, 2, ..., 254 to 255.
