Description

Sub-pixel rendering method, display device and mobile electronic device using the same

The present invention relates to the technical field of displays, and particularly refers to a sub-pixel rendering method and a display device and a mobile electronic device using the sub-pixel rendering method.

Electronic engineers familiar with display design and production must understand that LCD and OLED display devices include a bar-shaped RGB pixel structure (also known as a Real pixel structure). The strip-shaped RGB pixel structure includes a plurality of pixel units, and each pixel unit is composed of sub-pixels of R, G, and B colors. 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 in order to achieve the final effect of increasing the PPI, it is necessary to reduce the size of each sub-pixel as much as possible. Dimensions and their spacing between each other. However, due to the limitations of the manufacturing process, the size of the sub-pixels cannot be reduced indefinitely. Therefore, Sub Pixel Rendering (SPR) technology is proposed. Specifically, the SPR technology uses a reasonable arrangement of sub-pixels, combined with a certain algorithm (methodology), so that the low-PPI pixel structure has the display effect of the high-PPI pixel structure.

FIG. 1 shows a structure diagram of a conventional G2in1 pixel structure, and FIG. 2 shows a structure diagram of a conventional G2in1 pixel structure and a plurality of data lines. It can be seen from FIG. 1 that 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 unit P1a and the second pixel unit P2a are alternately interspersed Set up. It is worth noting that each of the first pixel units P1a includes a red sub-pixel Ra and a green sub-pixel Ga, and each of the second pixel units P2a includes a blue sub-pixel Ba and a green sub-pixel Ga. . Therefore, observing each column of the G2in1 pixel structure, it can be found that a first pixel unit P1a and a second pixel unit P2a include a red sub-pixel Ra, two green sub-pixels Ga, and a blue sub-pixel Ba. With this arrangement, compared with the traditional 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 to display, the luminance value of the red sub-pixel Ra and the blue sub-pixel Ba is half of the luminance value of the green sub-pixel Ga .

Please continue to refer to FIG. 3 and FIG. 3, where FIG. 3 shows a structure diagram of a conventional Delta pixel structure, and FIG. 4 shows a structure diagram of a conventional Delta pixel structure and a plurality of data lines. It can be seen from FIG. 3 that 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 unit P1b is connected to The second pixel unit P2b and the third pixel unit P3b are sequentially and repeatedly arranged. Wherein, each of the first pixel units P1b includes a red sub-pixel Rb and a green sub-pixel Gb, and each of the second pixel units P2b includes a blue sub-pixel Bb and a red sub-pixel Rb, and each of the second pixel units P2b includes a blue sub-pixel Bb and a red sub-pixel Rb. The third pixel unit P3b includes one green sub-pixel Gb and one 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 two red sub-pixels Rb, two green sub-pixels Gb, and two Blue sub-pixel Bb. With this arrangement, compared to the traditional 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 the first pixel unit P1b, the second pixel unit P2b, and/or the third pixel unit P1b are driven to display, the brightness values of the red sub-pixel Rb, the green sub-pixel Gb, and the blue sub-pixel Bb are all traditional Real Two-thirds of the brightness value of the red sub-pixel, green sub-pixel and blue sub-pixel of the pixel structure.

The aforementioned two pixel structures achieve the improvement of sensory resolution by sharing some sub-pixels between adjacent pixels, so that the display can achieve higher sensory resolution with the same sub-pixel arrangement density; or, keeping the same The requirement for the arrangement density of the display sub-pixels is reduced while the sensory resolution remains unchanged. As far as the pixel structure of the display panel currently used in mobile electronic devices is concerned, such as the G2in1 pixel structure or the Delta pixel structure, it can be used with the sub-pixel rendering algorithm (Rendering methodology) to deal with the situation of continuous color transition. However, when the color of the border area of the image changes rapidly (such as text, line and other border images), the sub-pixel rendering method used cannot accurately display the original contrast of the border area of the image, resulting in the border of the displayed image Regional distortion.
