Patent number: 11889719Abstract: A display panel is provided. The display panel includes at least two first pixels, at least two second pixels, and at least two third pixels. An area of the first pixel, an area of the second pixel, and an area of the third pixel are inversely proportional to a luminous efficiency of a luminescent material of the first pixel, a luminous efficiency of a luminescent material of the second pixel, and a luminous efficiency of a luminescent material of the third pixel, respectively. The disclosure can avoid the drawback of color shift of the display panel.Type: GrantFiled: July 30, 2020Date of Patent: January 30, 2024Assignee: WUHAN CHINA STAR OPTOELECTRONICS SEMICONDUCTOR DISPLAY TECHNOLOGY CO., LTD.Inventors: Yong Zhao, Liang Sun, Haokai Li

Patent number: 11522019Abstract: A display panel includes at least two pixel repeating units arranged in an array. Each of the pixel repeating units at least includes a first pixel, a second pixel, and a third pixel. A shape of the first pixel includes a convex arc, and each of shapes of the second pixel and the third pixel includes a convex arc and a concave arc. Shapes of edges of two of the first pixel, the second pixel, and the third pixel are complementary in at least one of a first direction, a second direction, a third direction, and a fourth direction, the first direction is perpendicular to the second direction, the third direction is a direction having an angle of less than 90 degrees with the first direction, and the fourth direction is perpendicular to the third direction.Type: GrantFiled: July 30, 2020Date of Patent: December 6, 2022Assignee: WUHAN CHINA STAR OPTOELECTRONICS SEMICONDUCTOR DISPLAY TECHNOLOGY CO., LTD.Inventors: Yong Zhao, Liang Sun, Haokai Li

Patent number: 11355556Abstract: A display panel includes a pixel arrangement structure. The pixel arrangement structure includes a plurality of first pixel rows and a plurality of second pixel rows arranged alternately. Each of the first pixel rows comprises a plurality of first pixels arranged at intervals, and each of the second pixel rows comprises a plurality of second pixels and a plurality of third pixels arranged alternately and at intervals. A shape of the first pixel comprises a shape formed by an arc. Each of the second pixel and the third pixel comprises a plurality of concave arcs and a plurality of convex arcs, the plurality of concave arcs and the plurality of convex arcs of the second pixel are alternately connected and form a closed figure, and the plurality of concave arcs and the plurality of convex arcs of the third pixel are alternately connected and form a closed figure.Type: GrantFiled: July 29, 2020Date of Patent: June 7, 2022Assignee: WUHAN CHINA STAR OPTOELECTRONICS SEMICONDUCTOR DISPLAY TECHNOLOGY CO., LTD.Inventors: Yong Zhao, Liang Sun, Haokai Li

Patent number: 10971054Abstract: A display panel has a ratio y1 of an aperture ratio of the red pixel to an aperture ratio of the green pixel being in the range of 0.78e{circumflex over (?)}(?1.98r)?y1?2.297e{circumflex over (?)}(?1.85r), and 0.1?y1?3, where r is a ratio of a luminous efficiency of the red pixel to a luminous efficiency of the green pixel. A ratio y2 of an aperture ratio of the blue pixel to the aperture ratio of the green pixel is in a range of 1.32e{circumflex over (?)}(?10.7b)?y2?5.95e{circumflex over (?)}(?14.1b), and 0.3?y2?4, where b is a ratio of a luminous efficiency of the blue pixel to the luminous efficiency of the green pixel.Type: GrantFiled: July 29, 2020Date of Patent: April 6, 2021Assignee: WUHAN CHINA STAR OPTOELECTRONICS SEMICONDUCTOR DISPLAY TECHNOLOGY CO., LTD.Inventors: Yong Zhao, Liang Sun, Haokai Li
