AI Technical Summary
Technical Problem
Mini LED displays suffer from poor image quality and low brightness in the edge areas, resulting in a poor user experience.
Method used
By adjusting the position of the encapsulation lens so that its center is closer to the center of the light-emitting device, and the offset distance meets specific conditions, the encapsulation lens can be used to cover the light-emitting device and change the light distribution, thereby enhancing the light output ratio of the edge area.
Benefits of technology
It improves the edge brightness and peripheral light effect of the display device, enhances the uniformity and brightness of the displayed image, and improves the user's display experience.

Abstract
A light-emitting substrate, a backlight module and a display device. The light-emitting substrate comprises a substrate, a plurality of light-emitting devices and a plurality of packaging lenses, wherein the substrate comprises a light-emergent surface and a backlight surface; the plurality of light-emitting devices are arranged on one side of the light-emergent surface of the substrate, and the plurality of light-emitting devices are arrayed in a row direction and a column direction and spaced apart from each other; and each of the plurality of packaging lenses correspondingly covers one light-emitting device. The light-emitting substrate comprises a central region and an edge region surrounding the central region, and in the edge region, the center of each packaging lens is closer to the central region relative to the center of a corresponding light-emitting device.
