Abstract

The invention discloses a pixel structure, a manufacturing method of the pixel structure, and a display panel. The pixel structure is used for reducing low gray scale color deviation, and comprises afirst sub-pixel and a second sub-pixel, wherein the first sub-pixel and the second sub-pixel are adjacently arranged; the first sub-pixel comprises a first electrode, a first transmission layer, a first light-emitting layer and a second electrode electrically opposite to the first electrode which are arranged in a stacked mode in sequence; the first transmission layer is used for adjusting the length of an optical cavity of the first sub-pixel; the second sub-pixel comprises a third electrode, a second transmission layer, a second light-emitting layer and a fourth electrode electrically opposite to the third electrode which are arranged in a stacked mode in sequence; the second transmission layer is used for adjusting the length of the optical cavity of the second sub-pixel; and the firsttransmission layer and the second transmission layer are partially or completely isolated. The first transmission layer and the second transmission layer are partially or completely isolated, and thenumber of carriers which are subjected to transverse crosstalk in the transmission layers can be reduced, so that the transverse crosstalk current is reduced, and then the low gray scale color deviation of the pixel structure is further lowered.

Description

technical field [0001] The present invention relates to the technical field of semiconductors, in particular to a pixel structure, a manufacturing method thereof, and a display panel. Background technique [0002] At present, most common display panels adopt a red, green, blue (RGB) three-color light-emitting pixel structure, and a fine mask plate is used in the manufacturing process of this structure. With the colorization, high resolution and large area of ​​the display panel, the fine mask directly affects the image quality of the display panel, so more stringent requirements are put forward for the dimensional accuracy and positioning accuracy of the fine mask. [0003] However, when the aperture ratio of the fine mask used is too large and the pixel per inch (PPI) is too high, the distance between the sub-pixels will be too close, resulting in the gap between the manufactured sub-pixels. There is a phenomenon that the organic film layers overlap with each other, wherei...
