Novel OLED pixel structure and arrangement method

Abstract

The invention discloses a novel OLED pixel structure and an arrangement method, a blue sub-pixel, a red sub-pixel and two green sub-pixels form a pixel unit, the blue sub-pixel and the red sub-pixel are both of a hexagonal structure, the two green sub-pixels are both of a horn-shaped structure, RGB sub-pixels are designed to be different in shape and size, and the pixel structure of the novel OLED is improved. Compared with a traditional OLED panel adopting standard RGB arrangement which is the same as that of a traditional LCD, namely, R, G and B are consistent in size and shape, the service life of an OLED blue light-emitting element is effectively prolonged, the problem of panel color cast caused by long-time display is solved, and the display effect of the OLED panel is improved. By changing RGB three-primary color distribution in pixels, the granular sensation of the screen made of the material is effectively reduced, the number of the pixels is reduced through the color borrowing principle without changing the display effect, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a novel OLED pixel structure and an arrangement method. Background technique [0002] The organic material in the OLED panel is driven by a current to emit light, and the brightness of the RGB three sub-pixels is adjusted to mix and superimpose to display a color picture. Compared with the LCD panel, it has the advantages of simple structure, high contrast, and low power consumption. [0003] The R, G, and B sub-pixels of the OLED panel use different organic materials. Since the blue luminescent material has the shortest service life and the lowest luminous efficiency, if the same standard RGB arrangement as the traditional LCD is adopted—the size and shape of R, G, and B are the same, after a long time of use, the luminous brightness of the blue sub-pixel will decrease. The phenomenon of panel yellowish cast occurs. [0004] Therefore, starting from the pixel shap...
