Partition lighting method and device, equipment and computer storage medium

The invention is suitable for the technical field of display, and provides a partition lighting method and device, equipment and a computer storage medium, which are applied to a passive lighting system. The passive lighting system comprises a light source array and a display chip, and the method comprises the steps: acquiring a target light taper angle corresponding to a target imaging range; and according to the target light taper angle, determining a light source area corresponding to the pixel subarea on the display chip on the light source array, wherein when the pixel subareas work and the light source area emits light, the light taper angle generated by the pixel subareas is consistent with the target light taper angle. According to the invention, when the pixel subarea works and the light source area emits light, the light cone angle generated by the pixel subarea is consistent with the target light cone angle corresponding to the target imaging range, the problem that stray light is generated due to
