Abstract

The present application belongs to the technical field of display. Disclosed are a chip structure and a manufacturing method therefor, and a display substrate. The chip structure comprises a first substrate, a light-emitting unit, a color conversion unit and a dam. The dam can be arranged around the light-emitting unit, and the maximum distance between the first substrate and the face of the dam facing away from the color conversion unit is greater than or equal to the maximum distance between the first substrate and the face of a first semiconductor layer in the light-emitting unit facing away from the first substrate. Therefore, after an optical waveguide phenomenon is generated inside the first semiconductor layer, light rays transversely transmitted in the first semiconductor layer can all be shielded by the dam after being emitted from any position of an edge. In this way, even if the optical waveguide phenomenon has occurred in light rays entering inside a first semiconductor, the light rays emitted from an edge of the first semiconductor can be shielded by means of providing the dam, thus effectively reducing the probability of a light leakage phenomenon occurring in the chip structure.

Abstract

The embodiments of the present application belong to the technical field of display. Provided are a display substrate and a preparation method therefor, and a display screen. In the display substrate, a first over coat can be filled into a first interval area and a second interval area, and the refractive index of the first over coat can be less than a first refractive index of a first isolation layer and can be less than a second refractive index of a second isolation layer. In this way, when emergent light rays enter the side faces of the first isolation layer and the second isolation layer through the first over coat, due to an increase in the refractive index, light rays with relatively large incident angles on the side faces of the first isolation layer and the second isolation layer can be totally reflected. That is, for the display substrate, emergent light with relatively large angles is totally reflected on the side surfaces of the first isolation layer and the second isolation layer, such that the angle between the reflected emergent light and the display substrate in a vertical direction is decreased, thereby implementing small-angle emergent light of a second-type pixel area; in addition, because there is more small-angle emergent light, the brightness of the small-angle emergent light can be increased.
