Embodiment Construction

[0035] In order for those skilled in the art to better understand the technical solutions of the present invention, the OLED display panel, its manufacturing method, and OLED display device provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Figure 1a A schematic structural diagram of the OLED display panel provided by the first embodiment of the present invention. see Figure 1a , the OLED display panel provided in this embodiment includes a light-emitting layer ER and a color filter CF. Wherein, the light-emitting layer ER includes a white sub-pixel W and a color sub-pixel, the size of the white sub-pixel W is equal to the sum of the sizes of at least two color sub-pixels, and the number of color sub-pixels is less than the number of primary colors forming a color. In this embodiment In the example, the number of primary colors forming a color is single, which are red, green and blue respectively; the col...

Abstract

The invention provides an OLED display panel and a manufacturing method thereof, and an OLED display apparatus. The OLED display panel comprises a light-emitting layer containing white sub pixels and colorful sub pixels; and the dimension of one white sub pixel is equal to the sum of dimensions of at least two colorful sub pixels and the number of the colorful sub pixels is less than the number of primary colors forming colors. Besides, the OLED display panel also includes a color membrane containing colorful stop blocks matching the colorful sub pixels; and the colorful stop blocks are arranged at one side, facing the display side, of the light-emitting layer and are located at positions corresponding to the location of the white sub pixels. With the OLED display panel, the qualities of the OLED display panel and the display apparatus can be improved; and one mask and evaporation process can be reduced, thereby improving the production efficiency. Therefore, the economic benefits are increased.

Description

technical field [0001] The invention belongs to the field of OLED display technology, and in particular relates to an OLED display panel, a manufacturing method thereof, and an OLED display device. Background technique [0002] Organic light-emitting diodes, also known as Organic Light-Emitting Diode (OLED) panels, have attracted widespread attention from academia and industry due to their high brightness, low power consumption, high contrast, and fast response time. It is considered to be a new display technology that can replace LCD in the next generation. [0003] The OLED display panel includes a front substrate, a rear substrate, and an anode layer, a light-emitting layer, and a cathode layer sequentially arranged between the front substrate and the rear substrate, wherein the light-emitting layer includes red sub-pixels (R), green sub-pixels (G) and The blue sub-pixel (B) controls the voltage between the anode layer and the cathode layer corresponding to R, G, and B a...
