Description

Pixel array, display, and method of presenting an image on a display

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.

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.

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 colors, and two colors cannot constitute all colors, so when actually displaying an image, one pixel unit of PenTile will "borrow" another one of its adjacent pixel units. The colors form the three primary colors. In the horizontal direction, each pixel unit and an adjacent pixel unit share sub-pixels of a color that they do not have, and collectively achieve the effect of white display.

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).

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.

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.
