The method includes: (1) dividing a display zone of a curved panel display zone into a plurality of panel grid cells and sequentially marking the plurality of grid cells as panel grid cells 1-n, where n is a natural number; (2) dividing a light guide plate located exactly under the curved panel display zone into a plurality of corresponding light guide plate grid cells, each of the light guide plate grid cells having a dot density being indicated by Pn; (3) measuring transmittance of each of the panel grid cells, the transmittance of each of the panel grid cells being indicated by tn; and (4) taking the transmittance tc of the panel grid cell c that is located close to a center of the curved panel display zone as a reference, where c is a natural number less than n and the dot density of the light guide plate grid cell c corresponding to the panel grid cell c is indicated by Pc, wherein the dot density Pn of a light guide plate grid cell n is set between Pc×0.25×tc/tn to Pc×4×tc/tn. The present invention helps eliminate dark zones of a curved module and improves the luminance uniformity without increasing the product design expenditure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for improving luminance uniformity of side-edge curved module","description":"The present invention relates to a method for improving luminance uniformity of a side-edge curved module.
