The problem that the reflection reduction layer is arranged on the color resistance of only one color and the color resistance of two colors is reduced, and reflected light is less. In one embodiment, as shown in fig. 3, the antireflection layer 26 is disposed on the red color resists 252a, the green color resists 252b and the blue color resists 252c, and the antireflection layer 26 fills the gaps between the adjacent color resists. The antireflection layer is arranged on the red color resistor, the green color resistor and the blue color resistor, so that the antireflection layer can reduce or even eliminate the reflected light of the color resistors of various colors, and the reflected light of the OLED display panel is reduced; meanwhile, the antireflection layer is filled in the gap between the adjacent color resistors, so that the antireflection layer can be arranged on the black matrix layer, the reflection of the black matrix layer to light is reduced, the possibility of color halo of the OLED display panel is reduced, the screen effect of the OLED display panel is improved, and the screen effect of the OLED display panel is improved.
The problem that the OLED display panel generates color halo in a screen-on state due to the fact that external light is reflected by the color resistance and the black matrix is solved. In one embodiment, the antireflection layer includes a first antireflection layer disposed between the black matrix layer and the color resist layer, and a second antireflection layer disposed on a side of the color resist layer away from the first antireflection layer. Through set up first antireflection coating between black matrix layer and look hinder the layer, one side of keeping away from first antireflection coating at the look hinders the layer sets up the second antireflection coating, then first antireflection coating can reduce or even eliminate the reflection ray on black matrix layer, OLED display panel's reflection ray has been reduced, and simultaneously, the second antireflection coating can reduce or even eliminate the reflection ray of look hinder, OLED display panel's reflection ray has been reduced, the possibility that OLED display panel appears "gloomy" has been reduced, OLED display panel's information screen effect is improved, OLED display panel's information screen display effect is improved.

Specifically, the materials of the first antireflection layer and the second antireflection layer are the same, so that when light passes through the first antireflection layer and the second antireflection layer, the reflected light can be offset by two times of reflection, the reflected light of the OLED display panel is reduced, the possibility of color halo of the OLED display panel is reduced, the screen effect of the OLED display panel is improved, and the screen display effect of the OLED display panel is improved.
In one embodiment, the phase difference of the reflected light rays of the upper surface and the lower surface of the antireflection layer is 180 degrees. The phase difference of the reflected light rays of the upper surface and the lower surface of the antireflection layer is 180 degrees, so that the reflected light rays of the upper surface and the lower surface of the antireflection layer can be cancelled by interference, the reflected light rays are weakened or even eliminated, and the phenomenon that the display panel is colorful due to the reflection of the colorful film layer to the light rays is avoided.
Specifically, as shown in fig. 4 and 5, after the external light 31 irradiates the antireflection layer 26, a first reflected light 32 is reflected on the upper surface, and at the same time, the external light 31 enters the antireflection layer 26 to obtain a transmitted light 33, a second reflected light 34 is formed on the surface of the antireflection layer 26 contacting with other film layers, and the waveforms of the first reflected light 32 and the second reflected light 34 are as shown in fig. 5, and the phase difference between the two is 180 degrees, so that the synthesized waveforms of the first reflected light 32 and the second reflected light 34 are straight lines, the two interferences are cancelled, and no reflected light is emitted, thereby reducing the reflected light of the OLED display panel, reducing the possibility of occurrence of "color halo" of the OLED display panel, improving the information display effect of the OLED display panel, and improving the information display effect of the OLED display panel.
Specifically, the abscissa in fig. 5 is time, and the ordinate is a waveform or a synthesized waveform corresponding to each reflected light.
In one embodiment, the material of the anti-reflective layer comprises one of indium tin oxide, silicon nitride and silicon oxide. The antireflection layer is made of a material with high transmittance, so that when the antireflection layer is arranged in the OLED display panel, the influence on the transmittance of light is small, and the transmittance of light cannot be influenced. When the silicon oxide and the silicon nitride are used for forming the antireflection layer, the original photomask is directly adopted, so that the preparation of the antireflection layer is facilitated.
Specifically, although the foregoing embodiments have described that the antireflection layer can solve the problem that the OLED display panel appears "halo" in the screen-saving state, according to the characteristics of the antireflection layer, when the OLED display panel is in the display state, because the antireflection layer can cancel interference of external light, when the OLED display panel normally displays, reflected light of the OLED display panel can also be reduced, thereby preventing the reflected light from interfering with light emitted by the OLED display panel, and improving the display effect of the OLED display panel.
