A method for manufacturing the array substrate comprises forming a transparent conductive layer and a first metallic layer on the substrate, forming patterned common electrode and light shielding layer by multiple steps of etching so that a process of photomask can be saved, and forming holes connecting with the common electrode and the gate by a photomask etching process, then manufacturing a medium layer and a source drain. The method adopts seven processes of photomask so that the process is simplified, and the cost is lowered."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low temperature poly-silicon (LTPS) thin film transistor based liquid crystal display","description":"An array substrate comprises a substrate, a common electrode formed on the substrate, a light shielding layer disposed on the common electrode, an insulating layer disposed on the light shielding laye","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9704884","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
