Description

Subpixel rendering method, display device and mobile electronic device using the same

The invention relates to the technical field of displays, in particular to a sub-pixel rendering method, a display device and a mobile electronic device using the same.

Electronic engineers who are familiar with display design and production must understand that LCD and OLED display devices include a strip-shaped RGB pixel structure (also known as a Real pixel structure). The stripe RGB pixel structure includes a plurality of pixel units, and each pixel unit is composed of sub-pixels of three colors of R, G, and B. Generally speaking, the resolution of the display device can be improved by increasing the number of pixels per inch (PPI) in the pixel structure, and to achieve the final effect of increasing the PPI, it is necessary to reduce the The size and the distance between them. However, due to the limitations of the manufacturing process, the size of the sub-pixels cannot be reduced infinitely. Therefore, Sub Pixel Rendering (SPR) is proposed. Specifically, the SPR technology is to make the low-PPI pixel structure have the display effect of the high-PPI pixel structure by reasonably arranging the sub-pixels and combining certain methods (methodology).

FIG. 1 shows a conventional G2in1 pixel structure, and FIG. 2 shows a conventional G2in1 pixel structure and a plurality of data lines. As can be seen from FIG. 1, each column of the G2in1 pixel structure includes a plurality of first pixel units P1a and a plurality of second pixel units P2a, and the first pixel units P1a are interspersed with the second pixel units P2a Settings. It is worth noting that each of the first pixel units P1a includes a red subpixel Ra and a green subpixel Ga, and each of the second pixel units P2a includes a blue subpixel Ba and a green subpixel Ga . Therefore, observing each column of the G2in1 pixel structure, it can be found that one first pixel unit P1a and one second pixel unit P2a include one red subpixel Ra, two green subpixels Ga, and one blue subpixel Ba. With this arrangement, compared to the conventional Real pixel structure, the single-point brightness of the first pixel unit P1a and the second pixel unit P2a is R=B=1/2, G=1. That is, when driving the first pixel unit P1a and/or the second pixel unit P2a for display, the luminance values of the red sub-pixel Ra and the blue sub-pixel Ba are half of the luminance values of the green sub-pixel Ga .

Please continue to refer to FIG. 3 and FIG. 3, wherein FIG. 3 shows an architecture diagram of a conventional Delta pixel structure, and FIG. 4 shows an architecture diagram of the conventional Delta pixel structure and a plurality of data lines. As can be seen from FIG. 3, each column of the Delta pixel structure includes a plurality of first pixel units P1b, a plurality of second pixel units P2b, and a plurality of third pixel units P3b, and the first pixel units P1b are The second pixel unit P2b and the third pixel unit P3b are sequentially arranged repeatedly. Each of the first pixel units P1b includes a red subpixel Rb and a green subpixel Gb, and each of the second pixel units P2b includes a blue subpixel Bb and a red subpixel Rb, and each Each of the third pixel units P3b includes a green sub-pixel Gb and a blue sub-pixel Bb.

Observing the columns of the Delta pixel structure, it can be found that a first pixel unit P1b, a second pixel unit P2b and a third pixel unit P3a include a total of two red sub-pixels Rb, two green sub-pixels Gb and two Blue sub-pixel Bb. In this way, compared to the conventional Real pixel structure, the single-point brightness of the first pixel unit P1b, the second pixel unit P2b, and the third pixel unit P1b is R=B=G=2/3. That is, when driving the first pixel unit P1b, the second pixel unit P2b, and/or the third pixel unit P1b for display, the luminance values of the red sub-pixel Rb, the green sub-pixel Gb, and the blue sub-pixel Bb are all conventional Real Two thirds of the luminance values of the red, green and blue sub-pixels of the pixel structure.

The aforementioned two pixel structures achieve the improvement of the sensory resolution by sharing a part of sub-pixels between adjacent pixels, so that the display can achieve a higher sensory resolution under the same sub-pixel arrangement density; or, the same Without changing the sensory resolution, the requirement for the arrangement density of the display sub-pixels is reduced. As for the pixel structure of the display panel currently used in mobile electronic devices, for example, the G2in1 pixel structure or the Delta pixel structure, its sub-pixel rendering algorithm (Rendering methodology) can handle the continuous color transition well. However, when the color of the boundary area of the image changes rapidly (such as text, lines and other edge images), the subpixel rendering method cannot accurately display the original contrast of the image boundary area, resulting in the display of the image boundary Area distortion.
