Description

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

technical field

The present invention relates to the field of display technology, in particular to a pixel array, a display including the pixel array and a method for presenting images on the display.

Background technique

Active Matrix Organic Light Emitting Diode (hereinafter referred to as AMOLED) is a new generation of display. 1( a ) to FIG. 1( e ) are schematic diagrams of various pixel arrays of an AMOLED display in the prior art.

A pixel unit of a traditional pixel array is composed of three sub-pixels of red, green and blue. However, the current AMOLED pixel array design tends to use an arrangement similar to PenTile technology. The individual pixels (or pixel units) of the PenTile pixel array are different, one is red and green, and the other is blue and green. We know that only three primary colors can make up all colors, and two colors cannot make up all colors, so when actually displaying an image, a pixel unit of PenTile will "borrow" another color from its adjacent pixel unit. colors to form the three primary colors. In the horizontal direction, each pixel unit shares the sub-pixel of the color it does not have with the adjacent pixel unit, and jointly achieves the effect of white display.

Because the current AMOLED has encountered a bottleneck in high-resolution products, because the current mainstream AMOLED evaporation technology is FMM (Fine Metal Mask), and its evaporation accuracy exceeds 200PPI in the normal pixel array method (stripe). The product is prone to the problem of color mixing (that is, the problem of low yield rate).

Therefore, the rendering pixel array method such as atypical PenTile pixel array is derived, which can save 1/3 of the number of sub-pixels, so as to solve the problem of insufficient precision of FMM evaporation. However, the PenTile arrangement is different from the real RGB sub-pixels after all. Due to the relationship of sharing sub-pixels, the boundaries of the discontinuous parts of the picture will appear blurred. However, the PenTile or the atypical PenTile pixel array method can also cause the problem of rough edges of the picture.

Accordingly, the present invention provides a new pixel array, a display comprising the pixel array, and a method of presenting an image on the display. The invention can not only save sub-pixels, but also overcome the defect of blurred picture edges existing in the pixel array in the prior art, and simultaneously improve evaporation precision, evaporation yield and image resolution.

The blue sub-pixels B, red sub-pixels R and green sub-pixels G are arranged vertically from top to bottom to form a first column, and the center points of the three sub-pixels are aligned in the vertical direction. Wherein, the shape of each sub-pixel is a rectangle, and its size is the same. The long side of each sub-pixel serves as the long axis, and the short side of each sub-pixel serves as the short axis. The distance between the centers of two adjacent sub-pixels is greater than or equal to the length of the projection of the short sides of the two sub-pixels in the horizontal direction, and is less than or equal to the length of the projection of the short sides of the three sub-pixels in the vertical direction. For example, the distance between the centers of the blue sub-pixel B and the red sub-pixel R in the first sub-pixel group 43 is greater than or equal to the length of the projection of the short sides of the two sub-pixels in the vertical direction (although the first sub-pixel is shown in the figure The distance between two adjacent sub-pixels of the pixel group 43 is equal to the length of the projection of the short sides of the two sub-pixels in the vertical direction). The long sides of the blue sub-pixel B, the red sub-pixel R, and the green sub-pixel G are respectively in directions rotated 45 degrees counterclockwise from the vertical direction.

The second subpixel group 44 is composed of a green subpixel G, a blue subpixel B, and a red subpixel R.
