Organic electroluminescent display panel. [Previous technology] In recent years, flat-panel displays have been trending toward the south in terms of brightness, flatness, thinness, and energy saving. In view of this, organic electroluminescent (OEL) display devices have become one of the most desirable development directions in the optoelectronic industry. Because it has the advantages of self-emission, no viewing angle limitation, power saving, simple manufacturing process, low cost, wide operating temperature range, high response speed, and full color, etc., it has great potential and is expected to become a new generation of flat display Mainstream. Organic electroluminescent display panels use the self-luminous properties of organic functional materials to achieve significant effects. 'According to the molecular weight of organic materials, organic electroluminescent display panels can be divided into small molecular organic electroluminescent display panels ( Small molecule OLED (SM-OLED) and polymer organic light-emitting display (PLED) two categories. At present, the full-color technology used in organic electroluminescent display panels can be divided into three types. The first one is the "three primary color luminescence method" which uses three primary colors of R, G, and B as independent light-emitting elements. The second one uses The blue material is combined with red and green organic phosphors or white light is combined with red, green, and blue organic phosphors to produce a variety of "color conversion methods"; the third is a white light emitting layer 1244878 with a color filter " "Color filter method", the "color conversion method" will be described below. As shown in FIG. 1, the full-color display panel 3 includes an organic electroluminescent region 31, a flat layer 32, a color conversion layer 33, and a substrate 34; the color conversion layer 33 is disposed on the substrate 34, and the flat layer 32 is It is provided on the color conversion layer 33, and the organic electro-excitation light region 31 is provided on the flat layer 32. Among them, the organic electroluminescence region 31 series includes at least one pixel, and the day element series φ includes a first electrode 311, an organic functional layer 312, and a second electrode 313 sequentially disposed on the flat layer 32.

Here, the white light emitted by the organic electro-optical excitation light region 31 is converted into blue light, green light, and red light by the blue conversion film 331 ', the green conversion film 332', and the red conversion film 333 ', respectively, and then the blue light, The green light and the red light pass through the blue filter 331, the green filter 332, and the red filter 333, respectively, so as to improve the individual color contrast values of the three primary colors of blue, green and red, and finally use the driving circuit to generate them. The three primary colors of R, G, and B are combined to form the required full-color daylight surface. However, in the conventional full-color display panel 3, due to the need for three mask processes up to 1244878, the blue filter 331, the green filter 332, and the red filter 333 are respectively formed into blue, The green and red color conversion films 331 ', 332', and 333 'have complicated manufacturing processes and high costs. At the same time, since the full-color display panel 3 must use a flat layer 32 to flatten the entire panel, the entire panel's Thickness does not conform to the trend of light, thin, short, and small. Because of this, the present invention is eager to consider a "optical modulation layer, an optical modulation substrate, and an organic electro-excitation light display panel" that can solve the above-mentioned problem.
