Problems solved by technology

Although using a color film instead of a polarizer has many advantages above, it will lead to an increase in the overall reflectivity of the display panel, making the reflectivity reach more than 6%, which in turn reduces the display contrast of the display panel
[0004] Therefore, the current display panel based on non-polarizer technology has the technical problem of high reflectivity

Abstract

The invention provides a display panel and a display panel manufacturing method. The display panel comprises a light-emitting layer, a packaging layer arranged on the light-emitting layer, a color filter layer arranged on the packaging layer and a light-transmitting layer arranged on the color filter layer, wherein the color filter layer comprises color resistors and shading components located between the color resistors, and a specific relational expression exists between the thickness d of the color resistors and the refractive index n of the color resistors. The thickness of the color resistors is designed according to the refractive index of the color resistors, so when light penetrates through the color resistors, reflected light emitted from upper interfaces and lower interfaces of the color resistors has destructive interference; and thus, the amount of the reflected light emitted from the surfaces of the color resistors is reduced, the reflectivity of the display panel is reduced, and the display contrast ratio of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a method for manufacturing the display panel. Background technique [0002] The polarizer (POL) can effectively reduce the reflectivity of the panel under strong light, but loses nearly 58% of the light output, which greatly increases the light-emitting burden of the diode for the organic light-emitting diode (OLED) display panel, resulting in its The lifespan is reduced; on the other hand, the thickness of the polarizer is large and the material is brittle, which is not conducive to the development of dynamic bending products. Therefore, in order to develop dynamic bending products based on OLED display technology, new materials, new technologies and new processes must be introduced to replace polarizers. [0003] At present, the use of color filters to replace polarizers is classified as POL-less technology, which can not only reduce the thicknes...
